Description

Method and device for processing temporary mobile group identity (tmgi)

A kind of interim mobile group identification TMGI processing method and equipment technical field

The present invention relates to wireless communication technology field, the more particularly to a kind of processing method and equipment of interim mobile group identification (Temporary Mobile Group Identity, TMGI).Background technology

Trunked communication system is that there is provided unidirectional delivery value for a kind of specific communication system with dispatching, it is allowed to which user equipment (User Equipment, UE) is communicated with one or more other users equipment.As mobile service becomes increasingly abundant, text, picture, video etc. all turns into the content of cluster communication, and traditional trunked communication system can not meet the demand of communication.Also, with Long Term Evolution（Long Term Evolution, LTE) technology development, realize that abundant group service is possibly realized in public LTE network, LTE group system Organization Charts are as shown in Figure 1.

Cluster communication can carry out the transmission of downlink data by unicast and multicast, determine to be communicated using unicast or multicast by the cluster communication service application moon good business device (Group Communication Service Application Server, GCS AS).Such as bright GCS AS determine the transmission using multicast progress downlink data, then broadcast-multicast service center（Broadcast-Multicast Service Centre, BM-SC) it can be used for recognizing the multicast carrying service of group for each one TMGI of group allocation.According to present third generation partner program（The 3^rdGeneration Partnership, 3GPP) standard agreement description, GCS AS can first to BM-SC initiate TMGI allocation flow, request BM-SC predistribution TMGI.When some group has downlink data to need to transmit by way of multicast, GCS AS will initiate multimedia broadcast multi-broadcasting business（Multimedia Broadcast Multicast Service, MBMS) bearing activation flow, activates the corresponding TMGI of the group, and set up multicast transmission carrying for the group.

The TMGI allocation flows that GCS AS are initiated are as shown in Fig. 2 comprise the following steps：

Step 1：GCS AS send distribution TMGI requests to BM-SC（Allocation TMGI request) message, the parameter in the message includes number of requested TMGIs (request TMGIs quantity）With list of TMGIs for allocation extension (the TMGIs lists of distribution of application for adjournment）. In the step, number of requested TMGIs marks GCS AS need to ask the TMGI of BM-SC predistribution quantity.If number of requested TMGIs value is 0, then the flow is all TMGIs application extension expiration time (effective times in the TMGI to have pre-allocated, i.e. list of TMGIs for allocation extension lists）；

Step 2:BM-SC confirms whether GCS AS are authorized to the TMGIs for receiving distribution, and TMGIs or the TMGIs of extended requests expiration time for its distribution request;

Step 3:BM-SC returns to distribution TMGI responses to GCS AS（Allocation TMGI response) message, the message include distribution TMGI list, TMGI expiration.The TMGI lists of TMGI list mark distribution, the corresponding expiration time of TMGI that TMGI expiration marks are each distributed.

In above-mentioned flow, while BM-SC is group allocation TMGI, one TMGI expiration time can be set for each TMGI.If within the time as defined in TMGI expiration time, corresponding TMGI is activated, then the TMGI expiration time just cease to be in force automatically；If TMGI expiration time are overtime, corresponding TMGI is not activated also, then the TMGI is just released.In above-mentioned flow, if the value of the parameter number of requested TMGIs in step 1 is 0, the function of the flow is that GCS AS are the TMGI application extension TMGI expiration time pre-allocated.

At present, if GCS AS will discharge the TMGI (s) pre-allocated, it can go allocation flow to discharge TMGI by TMGI as shown in Figure 3, specifically include following steps：

Step 1:GCS AS are sent to BM-SC goes distribution TMGI requests（Deallocation TMGI request) message, the parameter carried in the message includes list of TMGIs, and the parameter identification needs to go the TMGI lists of distribution.If not carrying the parameter in request message, then it represents that all TMGIs pre-allocated of distribution are removed in GCS AS requests;

Step 2:BM-SC confirms whether GCS AS are authorized to request and remove the TMGIs of distribution, and goes to distribute the TMGIs, while discharging the corresponding MBMS resources of the TMGIs；

Step 3:BM-SC returns to distribution TMGI responses to GCS AS（Deallocation TMGI response) message.

At present, GCS AS can pass through the MBMS load bearing deactivation flows (Deactivate shown in Fig. 4 MBMS Bearer Procedure), corresponding MBMS resources are carried to discharge MBMS, following steps are specifically included：

Step 1：MBMS bearer are just broadcasted in MBMS internal systems；

Step 2:GCS AS are sent to BM-SC deactivates MBMS carrying requests（Deactivate MBMS bearer request) message, the parameter carried in the message includes TMGI and traffic identifier（Flow ID), wherein, the specific MBMS carryings of TMGI and Flow ID common IDs one；Discharging corresponding MBMS is carried on the MBMS resources taken in MBMS systems simultaneously；

Step 4:BM-SC is returned to GCS AS deactivates MBMS carrying responses（Deactivate MBMS bearer response) message, the parameter carried in the message includes TMGI and Flow ID.

Allocation flow is gone to can be seen that from the TMGI shown in Fig. 3, BM-SC can also deactivate MBMS bearing resources corresponding with the TMGI while TMGI is discharged, that is to say, that, gone in TMGI in allocation flow, TMGI and MBMS bearing resources are always released together.And can be seen that from the MBMS load bearing deactivation flows shown in Fig. 4, BM-SC is received after GCS AS deactivation request message, corresponding MBMS bearing resources are only deactivated, carry how corresponding TMGI is handled for the MBMS of deactivation, specific solution is not provided in the prior art.If the corresponding all MBMS carryings of TMGI are all released, and still retain the TMGI, then the waste of resource can be caused；Further, since the quantity for the TMGI that BM-SC is distributed is limited, if discharge not in time without using TMGI, it is other group allocations TMGI that can influence BM-SC.

In summary, due in existing MBMS load bearing deactivations flow, only having deactivated corresponding MBMS bearing resources, having easily caused the waste of TMGI resources.The content of the invention
