Description

Method, system, base station and equipment for coordinating service resources

technical field

The present invention relates to the field of communication technology, in particular to a method, system, base station and equipment for coordinating service resources.

Background technique

MBMS (Multimedia Broadcast/Multicast Service, multicast/broadcast service) service refers to sending multimedia data to mobile terminals through broadcast or multicast by sharing a transmission link.

In MBMS, in order to enable the UE (User Equipment) to receive services better, the technology of air interface combination is used at the UE receiving end; on the network side, in order to support air interface combination, one MBMS service will be simultaneously transmitted in multiple cells , the transmission of multiple cells uses the same coding method, so the receiving end of the UE can receive signals of the same service with different power levels from adjacent cells, and the UE regards the signals of these different cells as different multipath components of a signal , by combining at the RAKE receiver and treating the combined signal as a signal input to the decoder, the signal-to-noise ratio (SNR) of the input decoder signal has a larger value than when only considering the signal of this cell gain. Such multiple cells that send the same MBMS service at the same time are called synchronous MBMS cells. For example, the composition of a synchronous MBMS cell is shown in Figure 1. In Figure 1, it includes 11 cells (cells), among which cell 1, cell 2, and cell 6 are synchronous MBMS cells that simultaneously send MBMS service 1; cell 4, cell 5 , cell 7, cell 8, cell9, cell 10 and cell 11 are synchronous MBMS cells, and send MBMS service 2 at the same time.

In the existing technology, there are multiple e-NodeBs (base stations) in a synchronous MBMS cell, including a master e-NodeB and multiple slave e-NodeBs. The master e-NodeB is responsible for assigning resources used by MBMS services, and establishing and processing MBMS The user plane entity of the service; the slave e-NodeB configures the physical layer according to the resource configuration requirements of the master e-NodeB, and then sends the processed data packets of the master e-NodeB to the physical layer.

At present, in MBMS, resource preemption is adopted for the coordination of MBMS service resources. Specifically, in a fixed physical area, multiple MBMS services will be sent at the same time, that is, one cell will send multiple MBMS services at the same time. , an MBMS service will also be sent simultaneously in multiple cells. Therefore, it will appear that one e-NodeB will belong to multiple synchronous MBMS cells at the same time. This requires that the resources used by each synchronous MBMS cell to transmit cannot be the same, that is, there is a one-to-one correspondence between resources and synchronous MBMS cells. After a synchronous MBMS cell uses a certain resource, it should notify other synchronous MBMS cells, and other synchronous MBMS cells will use the remaining resources to send the services of this synchronous MBMS cell. This method is called resource preemption. For example, as shown in Figure 2, in Figure 2, e-NodeB 3 belongs to synchronous MBMS cell A, synchronous MBMS cell B, and synchronous MBMS cell D, and e-NodeB 4 simultaneously belongs to synchronous MBMS cell B, synchronous MBMS cell C, and synchronous MBMS cell D, e-NodeB 3 and e-NodeB 4 notify each other of the resources they occupy, and adjust when a conflict is found.

The resource preemption method is effective when the number of master e-NodeBs is very small (less than 3). But when the number of primary e-NodeBs is greater than 3, the following problems will occur:

The interaction between the main e-NodeBs is very complicated. Every two main e-NodeBs must notify each other of the resources they occupy. If conflicts are found, adjustments will be made, which will lead to another notification. This process may cycle for a long time. The resource allocation process is relatively long; and resource conflicts often occur, requiring frequent adjustment of resource allocation.

Detailed ways

The method, system, base station, and equipment described in the embodiments of the present invention will be described in detail below with reference to FIG. 3 to FIG. 8 .

Firstly, the method described in the embodiment of the present invention will be described.

The method described in the embodiment of the present invention can set a main control entity in the specific implementation process, and the main control entity collects the resource usage conditions of a plurality of synchronous MBMS service cells through the primary base station and the secondary base station of the synchronous service cell, Coordinate the MBMS service resources of the MBMS service cell.

The specific process of resource coordination by the main control entity is shown in Figure 3, including the following steps:

Step 31: When the network sends an MBMS service, the master e-NodeB of each synchronous MBMS cell sends a report request to its subordinate slave e-NodeB, requesting the slave e-NodeB to send its resource usage status to the master e-NodeB ;

Step 32: After receiving the reporting request from the e-NodeB, send its own resource usage status to the master e-NodeB; here, the resource usage status can be divided according to the service type or service priority;

Step 33: The master e-NodeB receives all the resource usage status of the slave e-NodeB, and obtains its own resource usage status, and then processes these resource usage status, makes a resource status list of the synchronous MBMS cell, and points out the recommended MBMS The business resources that can be used by the business, that is, the preferred business resources;

Step 34, the main e-NodeB sends the resource status list and preferred service resources to the main control entity;

Step 35, after the main control entity obtains the resource status list and preferred service resources of all synchronous MBMS cells, selects service resources among the preferred service resources, and configures the service resources for use by multiple synchronous MBMS cells; if preferred If the service resource cannot be used (for example, the preferred service resource is occupied by other services), other resources can be selected. The principle of selecting other resources can be service priority or load size, etc.; then the main control entity sends the resource configuration status to all synchronous Primary e-NodeB of the MBMS cell.

Step 36: After the master e-NodeB receives the resource configuration information, it distributes it to multiple slave e-NodeBs under it respectively, and each slave e-NodeB of the synchronous MBMS cell performs resource configuration respectively.

The following example is used for illustration, as shown in FIG. 4 .

There are 4 synchronous MBMS cells in this area shown in Figure 4, and each synchronous MBMS cell has a primary e-NodeB, that is, the primary e-NodeB of synchronous MBMS service cell 1 is e-NodeB 1; synchronous MBMS service cell 2 The primary e-NodeB of the synchronous MBMS service cell 3 is e-NodeB 4; the primary e-NodeB of the synchronous MBMS service cell 4 is e-NodeB 10. Wherein, the master control entity is located on the e-nodeb 10.

When the four synchronous MBMS cells are to start transmitting MBMS services at the same time, the steps for the master control entity to coordinate service resources are as follows:

The master base station e-NodeB 10 of the synchronous MBMS cell 4 sends a request to allow the slave base station e-NodeB 8 and the slave base station e-NodeB 9 to send their service resource usage status;

The resource status of the e-NodeB 8 of the synchronous MBMS cell 4 sending itself is: the business of priority 1 occupies 5% of the resources, and the service of the priority 2 occupies 20% of the resources; the e-NodeB 9 of the synchronous MBMS cell 4 reports The own resource status is: business with priority 1 occupies 5% of resources, business with priority 2 occupies 20% of resources; business with priority 3 occupies 10% of resources. The e-NodeB 10 also obtains its own resource usage status: Priority 1 occupies 5% of resources, Priority 2 services occupy 19%; Priority 3 services occupy 10%. Priority 4 took up 14%;

The e-NodeB 10 makes a resource list according to the usage status of all resources, and points out the recommended idle resources, that is, the preferred resources, and sends this result to the main control entity on the main e-NodeB 10; similarly, other The three synchronous MNMS cells also send the resource list and preferred resources of the cell to the main control entity;

After the main control entity collects the resource list from e-NodeB 1, e-NodeB 4, e-NodeB 7 and e-NodeB 10, according to these resource lists and the requirements of each synchronous MBMS cell for MBMS priority, through an appropriate algorithm Processing, resource coordination is performed, that is, resources are allocated to the four synchronous MBMS cells. Those skilled in the art can easily perform the calculation of the above-mentioned algorithm, which will not be repeated here. The specific configuration can be as follows: synchronous MBMS cell 1 uses resource b, synchronous MBMS cell 2 uses resource m, synchronous MBMS cell 3 uses resource k, and synchronous MBMS cell 4 uses resource a, where b, m, k, a represent the main control entity Resources configured for each synchronous service cell according to the MBMS priority;

The master control entity notifies the master e-NodeB of the corresponding synchronous MBMS cell of the resource configuration situation respectively, after e-NodeB 1, e-NodeB 4, e-NodeB 7 and e-NodeB 10 receive the resource configuration information, they send the resource configuration information Send it to each slave e-NodeB;

If the master e-NodeB finds that the resource configured by the master control entity is being occupied by other services in the cell, it will re-adjust the resource-occupied service to other idle resources;

Send the MBMS service resource configuration from the e-NodeB to its own cell, and configure the bearer and transport channels and the corresponding physical layer.

The master control entity in the embodiment of the present invention may be a master e-NodeB in the given area, or may be a physical entity added to the network, which will be described in detail below.

The specific location of the main control entity is shown in Figure 5, Figure 6 and Figure 7. Among them, in Fig. 5, the master control entity is located on e-NodeB1, and e-NodeB1 is the master e-NodeB of synchronous MBMS cell 1; e-NodeB6 is the master e-NodeB of synchronous MBMS cell 2; in Fig. 6, the master control entity Located on the SGSN (Serving GPRS Support Node), e-NodeB1 is the primary e-NodeB of the synchronous MBMS cell 1, and e-NodeB6 is the primary e-NodeB of the synchronous MBMS cell 2. In Fig. 7, the master control entity is a single entity in the network, e-NodeB1 is the master e-NodeB of synchronous MBMS cell 1, and e-NodeB6 is the master e-NodeB of synchronous MBMS cell 2.

In addition, since the division principle of the synchronous MBMS cell is the MBMS service, if there is no UE receiving the MBMS service in all the cells under a primary e-NodeB, the primary e-NodeB will exit the synchronous MBMS cell. When the master e-NodeB exits the MBMS cell, a slave NodeB must be reselected as the new master e-NodeB. After the new master e-NodeB is selected, the new master e-NodeB establishes a connection with the slave NodeB. Then start the context migration process of the master e-NodeB.

The migration process of the master e-NodeB is shown in Figure 8, which may specifically include the following steps:

The new master e-NodeB establishes a connection with the slave e-NodeB, which is used for transferring MBMS service data after the migration process is completed;

The original master e-NodeB sends a master e-NodeB relocation request to the SGSN, and the request message carries the network identifier of the new master e-NodeB, the original master e-NodeB network identifier, and the MBMS service identifier;

After receiving the migration request, the SGSN sends the migration request to the new master e-NodeB;

The new primary e-NodeB receives the migration request and sends a response to the SGSN;

The SGSN sends a relocation confirmation to notify the original master e-NodeB that relocation can be performed. After receiving the migration confirmation, the original master e-NodeB notifies the master control entity that the master e-NodeB has been replaced, and the message includes the identity of the new master e-NodeB. The main control entity establishes a connection with the new main e-NodeB through the main base station replacement confirmation message;

The original master e-NodeB sends all context data to the new master e-NodeB, and the new master e-NodeB reports that the SGSN has started migration. After receiving the context packet, the new master e-NodeB reports that the SGSN migration is complete;

SGSN releases the IU connection established between the original master e-NodeB and SGSN;

SGSN continues to send MBMS service data to the new master e-Nodeb.
