Description

Method for managing multicast broadcast service flow and base station

technical field

The present invention relates to the communication field, in particular, to a management method and a base station for a multicast broadcast service flow in a Worldwide Interoperability for Microwave Access (WiMAX) network.

Background technique

Broadband wireless access WiMAX technology is a broadband wireless technology based on the IEEE 802.16 standard for wireless metropolitan area networks. At present, there are advanced base stations (Advanced Base Station, referred to as ABS), advanced base stations can be compatible with traditional terminals (Yardstick MobileStation, referred to as YMS), similarly, advanced terminals (Advanced Mobile Station, referred to as AMS) should also be able to access traditional Base Station (Yardstick Base Station, referred to as YBS). The time zone (Time Zone) of advanced base stations can be divided into two zones, namely the first zone (also known as the advanced zone, 16m Zone, referred to as MZone) and the second zone (also known as the traditional zone, Legacy Zone, referred to as LZone ). The advanced terminal can work in the first area, or it can be converted to the working mode of the traditional terminal to work in the second area.

Advanced terminals supporting multi-carriers can be divided into two types: single radio terminals and multiple radio terminals. A channel corresponds to a radio frequency module (Radio Frequency, referred to as RF) of the physical layer, and a channel can work on a carrier frequency point of the system.

The carriers of the advanced base station supporting multiple carriers can be divided into fully configured carriers and partially configured carriers. A fully configured carrier refers to a carrier configured with all control channels, including synchronization channels, broadcast channels, multicast channels, and unicast channels, as well as channels related to multi-carrier operation and information and parameters of other carriers. A partially configured carrier refers to a carrier configured with only basic control channels used to support service interaction in multi-carrier operation. A fully configured carrier can be used as a main carrier or a secondary carrier for a terminal supporting multiple carriers, and a partially configured carrier can only be used as a secondary carrier for the above-mentioned terminal. Each terminal supporting multiple carriers can only have one primary carrier, and may have one or more secondary carriers, or may have no secondary carrier. If a terminal supporting multiple carriers uses a secondary carrier, the base station needs to allocate a secondary carrier for it, and then activate the secondary carrier according to its service conditions.

For terminals supporting multiple carriers, the following two operating modes are specified: carrier aggregation and carrier switching. Carrier aggregation means that the above-mentioned terminal always maintains a physical connection with the main carrier and monitors the control information transmitted on it. Carrier switching means that the terminal switches its physical connection from the main carrier to the auxiliary carrier through the instruction information of the base station. After the carrier is connected, the terminal does not need to maintain a physical connection with its main carrier, and only needs to return to the main carrier according to a preset period or trigger condition.

Multicast Broadcast Service (MBS) is a point-to-multipoint service that provides a data source to transmit data to multiple users in a mobile network. It can realize network resource sharing and improve the utilization of network resources, especially air interface resources. Rate. The WiMAX-based MBS service supports two access modes: single base station access and multiple base station access. In the multi-base station access mode, there is the concept of MBS zone (MBS zone), that is, a set of base stations. Each MBS zone corresponds to an MBS zone ID (MBS zone ID). A base station can belong to multiple MBS zones at the same time. Each MBS zone can provide multiple MBS services (MBS service). In the latest WiMAX advanced system, a multicast connection is indicated by a multicast connection identifier (Multicast Station ID, MSTID for short).

Advanced base stations need to support enhanced multicast broadcast services (Enhanced MBS, referred to as E-MBS), that is, the system needs to realize multicast broadcast of high-speed multimedia services, and at the same time, it needs to reduce the power consumption of terminals. Therefore, multi-carriers and E-MBS can be combined to meet the requirements of high throughput and high speed. There are two ways to carry E-MBS services on multiple carriers: one is dedicated carrier mode, that is, E-MBS service monopolizes all time-frequency resources on a certain carrier; the other is mixed carrier mode, that is, E-MBS The service and the unicast service share time-frequency resources on the carrier. Multiple E-MBS services in multiple E-MBS domains can be allocated arbitrarily on multiple carriers supported by the system. Therefore, how to complete the establishment and modification of multicast broadcast service flows according to the characteristics of the multi-carrier system, and reasonably distribute Sending E-MBS-related control information on multiple carriers not only ensures the power saving requirements of terminals, but also reduces signaling overhead, which is an urgent problem to be solved when sending multicast broadcast services under multiple carriers.

Embodiment one

As shown in FIG. 1 , in this embodiment, the terminal is a terminal supporting carrier aggregation. The terminal sends a service flow establishment request message (AAI-DSA-REQ) to the base station on the main carrier, requesting to establish a multicast broadcast service flow. After receiving the AAI-DSA-REQ message sent by the terminal, the base station sends a service flow establishment response message (AAI-DSA-RSP), and the message carries multicast broadcast service flow parameters, including at least one of the following: the multicast broadcast The connection identification information of the service flow, the service identification information of the multicast broadcast service flow, the MBS Zone identification information to which the multicast broadcast service flow belongs, the indication information of the area where the multicast broadcast service flow is located, and the corresponding One or more carrier identification information. The carrier identification information is the physical frequency point information of the carrier, the physical carrier number or the logical carrier number. In particular, for a terminal that does not support multi-carrier capabilities, it is necessary to use the carrier's physical frequency point information in the service flow establishment message. If the service flow establishment message does not include the carrier identification information, it indicates that the carrier carrying the multicast broadcast service flow is the current carrier. In this example, the carrier identification information is the physical carrier number of the carrier.

If the carrier is not the carrier that the base station has allocated for the terminal, the base station uses an AAI-DSA-RSP message to allocate and activate the carrier for the terminal, and the service flow establishment message may carry the allocation and/or activation carrier action execution time, if the The carrier is a carrier that the base station has allocated to the terminal but has not been activated. The base station uses an AAI-DSA-RSP message to activate the carrier, and the service flow establishment message may carry an action time for activating the carrier. The terminal may or may not send a response to assigning or activating a carrier. Specifically, the terminal may respond to activation of the secondary carrier through an AAI-DSA-ACK message.

After the terminal obtains the carrier where the established multicast broadcast service flow is located, it receives the system configuration description message (AAI-SCD message) broadcast by the base station on the carrier, and the message carries the multicast broadcast of the multicast broadcast service carried by the carrier Service parameters, including at least one of the following: Zone ID information of the MBS Zone to which the base station belongs; MBS area information of the MBS Zone to which the base station belongs; E-MBSMAP information of the MBS Zone to which the base station belongs, for example, E-MBS MAP Location information, indication information of whether the E-MBS MAP has changed, the modulation and coding method of the E-MBS MAP; the MBS subframe frequency partition configuration and resource division information of the MBSZone to which the base station belongs.

A specific example of the multicast broadcast service parameters carried in the AAI-SCD message is shown in Table 1:

Another example of the multicast broadcast service parameters carried in the AAI-SCD message is shown in Table 2:

The terminal parses the AAI-SCD message on the carrier, and receives the E-MBS service on the carrier according to its content.

When the area indication information is carried in the service flow establishment message, the terminal reads the value of the area indication information. Specifically, the area indication information can be identified by 1 bit. When the area indication information value is 0, it indicates that the multicast broadcast service flow Located in MZone, when the value of the area indication information is 1, it indicates that the multicast broadcast service flow is located in LZone, and vice versa, if it is indicated that the multicast broadcast service flow is located in LZone, the terminal will switch to the traditional terminal working mode, and the carrier identification information The multicast broadcast service flow is received on the LZone of the indicated carrier.

Embodiment two

The base station sends a service flow establishment request message (AAI-DSA-REQ) to the terminal on the main carrier of the terminal to establish multiple multicast broadcast service flows for it, and carries multicast broadcast service flow parameters in the message, including at least the following One: the connection identification information of the multicast broadcast service flow, the service identification information of the multicast broadcast service flow, the MBS Zone identification information to which the multicast broadcast service flow belongs, the indication information of the area where the multicast broadcast service flow is located, and the multicast broadcast service flow One or more carrier identification information corresponding to the flow.

Specifically, when multiple multicast broadcast service flows are established, each multicast broadcast service flow uses a multicast broadcast service flow connection identifier and a flow identifier to identify, or multiple multicast broadcast service flows use a multicast broadcast service flow The service flow connection identifier is identified with multiple flow identifiers. The above multiple multicast broadcast service streams may be located on one or more carriers. In this example, the established multicast broadcast service flows are located on the same carrier.

Specifically, the above-mentioned carrier identification information is physical frequency point information of the carrier, a physical carrier number or a logical carrier number. In particular, for a terminal that does not support multi-carrier capabilities, it is necessary to use the carrier's physical frequency point information in the service flow establishment message. If the service flow establishment message does not include the carrier identification information, it indicates that the carrier carrying the multicast broadcast service flow is the current carrier. In this example, the carrier identification information is the physical carrier number of the carrier.

If the carrier is not the carrier that the base station has allocated for the terminal, the base station uses an AAI-DSA-REQ message to allocate and activate the carrier for the terminal, and the service flow establishment message may carry the allocation and/or activation carrier action execution time, if the The carrier is a carrier allocated by the base station for the terminal but not activated. The base station uses an AAI-DSA-REQ message to activate the carrier, and the service flow establishment message may carry an action time for activating the carrier. The terminal may or may not send a response to assigning or activating a carrier. Specifically, the terminal may respond to activation of the secondary carrier through an AAI-DSA-RSP or AAI-DSA-ACK message.

After obtaining the carrier where the established multicast broadcast service stream is located, the terminal receives the system configuration description message (AAI-SCD message) broadcast by the base station on the carrier, and the message carries the multicast broadcast of the multicast broadcast service carried by the carrier Service parameters, including at least one of the following: Zone ID information of the MBS Zone to which the base station belongs; MBS area information of the MBS Zone to which the base station belongs; E-MBSMAP information of the MBS Zone to which the base station belongs, for example, E-MBS MAP Location information, indication information of whether the E-MBS MAP has changed, the modulation and coding method of the E-MBS MAP; the MBS subframe frequency partition configuration and resource division information of the MBSZone to which the base station belongs.

The terminal parses the AAI-SCD message on the carrier, and receives the E-MBS service on the carrier according to its content.

When the zone indication information is carried in the service flow establishment message, the terminal reads the value of the zone indication information. Specifically, 1 bit can be used for identification. When the value of the zone indication information is zero, it indicates that the multicast broadcast service flow is located in MZone. When the value of the area indication information is 1, it indicates that the multicast broadcast service flow is located in LZone, and vice versa. If it is indicated that the multicast broadcast service flow is located in LZone, the terminal switches to the traditional terminal working mode on the carrier indicated by the carrier identification information The multicast broadcast service flow is received on the LZone.

Embodiment Three

In this embodiment, the terminal is a terminal supporting carrier aggregation. The terminal sends a service flow establishment request message (AAI-DSA-REQ) to the base station on the main carrier, requesting to establish a multicast broadcast service flow. After receiving the AAI-DSA-REQ message sent by the terminal, the base station sends a service flow establishment response message (AAI-DSA-RSP), and the message carries multicast broadcast service flow parameters, including at least one of the following: the multicast The connection identification information of the broadcast service flow, the flow identification information of the multicast broadcast service flow, the MBS Zone identification information to which the multicast broadcast service flow belongs, the indication information of the area where the multicast broadcast service flow is located, the multicast broadcast service flow Corresponding to one or more carrier identification information, the carrier identification information is the physical frequency point information of the carrier, the physical carrier number or the logical carrier number. In particular, for a terminal that does not support multi-carrier capabilities, it is necessary to use the carrier's physical frequency point information in the service flow establishment message. If the service flow establishment message does not include the carrier identification information, it indicates that the carrier carrying the multicast broadcast service flow is the current carrier. In this example, the carrier where the multicast broadcast service is located is the carrier that has been allocated to the terminal, so the carrier identification information adopts the logical carrier number of the carrier.

If the carrier is not yet activated, the base station uses an AAI-DSA-RSP message to activate the carrier for the terminal, and the service flow establishment message may carry an action time for activating the carrier. The terminal may or may not send a response to the activated carrier. Specifically, the terminal may respond to activation of the secondary carrier through an AAI-DSA-ACK message.

After the terminal obtains the carrier where the established multicast broadcast service flow is located, it receives the system configuration description message (AAI-SCD message) broadcast by the base station on the carrier, and the message carries the multicast broadcast of the multicast broadcast service carried by the carrier Service parameters, including at least one of the following: Zone ID information of the MBS Zone to which the base station belongs; MBS area information of the MBS Zone to which the base station belongs; E-MBSMAP information of the MBS Zone to which the base station belongs, for example, E-MBS MAP Location information, indication information of whether the E-MBS MAP has changed, the modulation and coding method of the E-MBS MAP; the MBS subframe frequency partition configuration and resource division information of the MBSZone to which the base station belongs.

The terminal parses the AAI-SCD message on the carrier, and receives the E-MBS service on the carrier according to its content.

When the zone indication information is carried in the service flow establishment message, the terminal reads the value of the zone indication information. Specifically, 1 bit can be used for identification. When the value of the zone indication information is zero, it indicates that the multicast broadcast service flow is located in MZone. When the value of the area indication information is 1, it indicates that the multicast broadcast service flow is located in LZone, and vice versa. If it is indicated that the multicast broadcast service flow is located in LZone, the terminal switches to the traditional terminal working mode on the carrier indicated by the carrier identification information The multicast broadcast service flow is received on the LZone.

Embodiment Four

As shown in FIG. 3 , in this embodiment, the terminal is a terminal that supports carrier switching. The base station sends a service flow establishment response message (AAI-DSA-RSP) on the main carrier of the terminal to establish a multicast broadcast service flow for the terminal, and carries multicast broadcast service flow parameters in the message, including at least one of the following: The connection identification information of the multicast broadcast service flow, the service identification information of the multicast broadcast service flow, the MBS Zone identification information to which the multicast broadcast service flow belongs, the indication information of the area where the multicast broadcast service flow is located, the multicast broadcast service flow One or more carrier identification information corresponding to the service flow, where the carrier identification information is the carrier's physical frequency point information, physical carrier number or logical carrier number. In particular, for a terminal that does not support multi-carrier capabilities, it is necessary to use the carrier's physical frequency point information in the service flow establishment message. If the service flow establishment message does not include the carrier identification information, it indicates that the carrier carrying the multicast broadcast service flow is the current carrier. In this example, the carrier identification information is the physical carrier number of the carrier.

If the carrier indicated in the carrier identification information is a fully-configured carrier that only supports advanced protocols or a fully-configured carrier that supports both advanced and traditional protocols, the base station uses the service flow establishment message to perform primary carrier switching for the terminal, if the The carrier indicated in the carrier identification information is a carrier that only supports traditional protocols. The base station uses the service flow establishment message to perform area switching for the terminal. If the carrier is a partially configured carrier, the base station uses the AAI-DSA-RSP message as The terminal performs auxiliary carrier allocation or re-allocation, that is, allocates the part of configured carriers for the terminal. When the service flow establishment message is used to perform primary carrier switching or area switching for the terminal, the service flow establishment message also needs to carry the action execution time, and the service flow establishment message is used to perform secondary carrier allocation/relocation for the terminal When allocating, the service flow establishment message needs to carry parameters of action execution time and/or carrier switching period. In this example, the carrier carrying the multicast broadcast service is a carrier that only supports advanced protocols.

After obtaining the carrier where the established multicast broadcast service flow is located, the terminal performs primary carrier switching according to the action execution time, and then receives the system configuration description message (AAI-SCD message) broadcast by the base station on the carrier, which carries the carrier The multicast broadcast service parameters of the carried multicast broadcast service include at least one of the following: Zone ID information of the MBS Zone to which the base station belongs; MBS area information of the MBS Zone to which the base station belongs; E-ID information of the MBS Zone to which the base station belongs. MBS MAP information, for example, the location information of E-MBSMAP, the indication information of whether E-MBS MAP has changed, the modulation and coding method of E-MBS MAP; the MBS subframe frequency partition configuration and resource division information of the MBS Zone to which the base station belongs.

The terminal parses the AAI-SCD message on the carrier, and receives the E-MBS service on the carrier according to its content.

When the zone indication information is carried in the service flow establishment message, the terminal reads the value of the zone indication information. Specifically, 1 bit can be used for identification. When the value of the zone indication information is zero, it indicates that the multicast broadcast service flow is located in MZone. When the value of the area indication information is 1, it indicates that the multicast broadcast service flow is located in LZone, and vice versa. If it is indicated that the multicast broadcast service flow is located in LZone, the terminal switches to the traditional terminal working mode on the carrier indicated by the carrier identification information The multicast broadcast service flow is received on the LZone.

Embodiment five

As shown in Fig. 4, the base station sends a service flow change message (AAI-DSC-REQ) on the main carrier of the terminal to change the parameters of the current multicast broadcast service flow for the terminal. The AAI-DSC-REQ message can be used to change the parameters of one or more service flows for the terminal.

The base station carries the updated multicast broadcast service flow parameters in the AAI-DSC-REQ message, including at least one of the following: the updated connection identification information of the multicast broadcast service flow, the updated service identification information of the multicast broadcast service flow, the updated The MBS Zone identification information to which the multicast broadcast service flow belongs, the area indication information where the multicast broadcast service flow is located, and the updated identification information of one or more carriers corresponding to the multicast broadcast service flow, specifically, the above carrier identification The information may be physical frequency point information, physical carrier number, and logical carrier number of the carrier.
