- FIG. 2 is a diagram showing a correspondence relationship between a radio communication system to which an embodiment of the present invention is applied and a bearer service.
- FIG. 3 is a block diagram of an upper station according to an embodiment of the present invention.
- FIG. 4 is a diagram showing an example of a quality information management table of a higher station according to an embodiment of the present invention.
- FIG. 5 is a configuration example in which various data are multiplexed.
- FIG. 6 is a data flow according to a packet transmission method according to an embodiment of the present invention.
- FIG. 7 Diagram showing an example of the correspondence between bearer service and Diffserv
- FIG. 1 is a diagram showing a wireless communication system 10 to which an embodiment of the present invention is applied.
- the wireless communication system 10 includes an upper station 101, a base station 103, and a mobile station 105.
- the upper station 101 is a control device that receives data from another network and transmits the received data to the mobile station via the base station, like an access gateway (aGW).
- aGW access gateway
- packets having the same QoS requirement are multiplexed in an upper layer of the protocol layer.
- the upper station 101 has a multiplexing control device MUX, which identifies packet quality information and multiplexes packets for each QoS requirement.
- the upper station 101 can transmit the packet to the mobile station 105 via the base station 103 in accordance with the QoS requirement.
- Bearer service is a physical or logical service for transferring packets in a wireless network.
- Each bearer service has attributes that characterize the bearer service (capacity, loss rate, delay, etc.). ) And its value.
- the bearer service may be set as a default at the time of initial connection, like a signaling information bearer service or a best-effort type bearer service. Also, it can be set at the time of call connection like VoIP service or IP-TV service!
- the bearer service defined by 3GPP includes an access bearer provided between the upper station 101 and the base station 103. Services and radio bearer services provided between the base station 103 and the mobile station 105 are included.
- the upper station 101 When the bearer service defined as described above is used, the upper station 101 multiplexes packets for each QoS requirement and transmits the multiplexed packets to the base station 103. At this time, the frame protocol (FP) header is transmitted including the bearer ID which is the identifier of the (wireless) bearer service.
- the base station 103 executes scheduling and HARQ processing along with ARQ (Automatic Repeat request) processing provided by the radio bearer service, and transmits the multiplexed packet to the mobile station 105.
- FP frame protocol
- various QoS data can be efficiently wirelessly transmitted.
- FIG. 3 is a configuration diagram of the upper station 101 according to the embodiment of the present invention, and particularly shows the multiplexing control device MUX of FIG. 1 in detail.
- the upper station 101 includes a packet reception unit 111, a quality information extraction unit 113, and a multiplexing unit 115.
- the packet receiving unit 111 also receives a packet with the connected network power.
- the quality information extraction unit 113 extracts quality information from the packet received by the packet reception unit 111.
- the quality information may be any information that characterizes the bearer service that includes only the QoS class information. For example, the source (src) and destination (dest) included in the IP packet header are the same (or within the same range), and either the protocol or the port number is the same (or within the same range) If this is the case, such packets are likely to be using the same service and are considered to have the same QoS requirements. In this way, IP bucket header information may be treated as quality information. Also, if there is a delay requirement in the packet, treat this delay condition as quality information.
- the multiplexing unit 115 multiplexes the packet received by the packet receiving unit 111 by mapping to the bearer service for each quality information extracted by the quality information extracting unit 113.
- the bearer service may be set at the time of initial connection or may be set at the time of call connection.
- Multiplexing section 115 may assign an identifier called bearer ID to the packet and map it to each bearer service. Specifically, mapping may be performed by including the bearer ID in the header of the frame protocol (FP) and using the IP header used for transport between the upper station and the base station.
- FP frame protocol
- the upper station 101 may further include a quality information management table 117 for multiplexing the packets, and the multiplexing unit 115 refers to the quality information management table 117 and transfers the packet for each quality information. You can map it to ibis.
- a quality information management table Figure 4 shows an example.
- the quality information management table 117 is a table for managing the header information of the IP packet and the bearer service to be assigned in association with each mobile station.
- the quality information management table 117 manages a table for each mobile station, and manages a transmission source IP address, a destination address, a transport layer protocol, a port number, and an assigned bearer ID for each mobile station.
- the source IP address is an arbitrary address of the source network
- the destination IP address is an address that identifies the destination mobile station.
- the service is specified by the transport layer protocol and the port number. As mentioned above, the address, protocol and port number may be specified within a certain range.
- Fig. 5 shows a configuration example in which various data are multiplexed.
- the upper station multiplexes packets for different QoS requirements according to the data, and maps packets with the same QoS requirements to the same bearer service.
- the mapped bearer service is mapped to a class corresponding to Diffserv in the transport channel between the upper station and the base station, for example.
- FIG. 6 is a data flow according to the packet transmission method according to the embodiment of the present invention
- FIG. 7 is a diagram illustrating an example of a correspondence relationship between a bearer service and Diffserv.
- the packet (D01) When the upper station receives the packet (D01), the packet (D01) is header-compressed (D03) and ciphered (D05) according to the header compression and secrecy provided by the bearer service.
- the packet (D07) to which the bearer ID is assigned is based on the bearer ID! / (D09).
- a plurality of bearer IDs may be associated with Si Diffdiff classes.
- This packet (D09) is transmitted to the base station in the lower layer (Dll) o
- the base station also restores the packet with the received packet (Dl 1) power (D13).
- the base station performs ARQ processing provided by the radio bearer service and adds an ARQ header (D15).
