Description

Method and device for processing temporary mobile group identification TMGI

The present invention relates to the field of wireless communication technologies, and in particular, to a method and a device for processing Temporary Mobile Group Identity (TMGI). Background technique

The trunking communication system is a special communication system with scheduling capability, which provides one-way communication capability and allows user equipment (UE) to communicate with one or more other user equipments. With the increasing enrichment of mobile services, text, pictures, and video have become the content of cluster communication. Traditional trunking communication systems have been unable to meet the needs of communication. Moreover, with the development of the Long Term Evolution (LTE) technology, it is possible to implement rich cluster services on the public LTE network. The architecture diagram of the LTE cluster system is shown in FIG.

The cluster communication can transmit downlink data through unicast and multicast, and the group communication service application server (GCS AS) decides whether to use unicast or multicast for communication. If the GCS AS decides to use multicast for downlink data transmission, the Broadcast-Multicast Service Centre (BM-SC) assigns each group a TMGI to identify the multicast bearer of the group. service. According to current Third Generation Partnership Project Description ^{(The 3 rd Generation Partnership, 3GPP} ) standard protocol, GCS AS will first launch BM-SC TMGI allocation process, the request BM-SC pre-assigned TMGI. When a group has downlink data to be transmitted by multicast, the GCS AS initiates a multimedia broadcast multicast service (MBMS) bearer activation process, activates the TMGI corresponding to the group, and The group establishes a multicast transmission bearer.

The TMGI distribution process initiated by GCS AS is shown in Figure 2 and includes the following steps:

Step 1: The GCS AS sends an Allocation TMGI Request message to the BM-SC, and the parameters in the message include number of requested TMGIs and the list of TMGIs for allocation extension (application for deferred allocated TMGIs) List). In this step, the number of requested TMGIs identifies the number of TMGIs that the GCS AS needs to request for BM-SC pre-allocation. If the value of number of requested TMGIs is 0, the flow is used to extend the expiration time (valid time) for all TMGIs in the list of TMGIs for allocation extensions that have been pre-allocated;

Step 2: The BM-SC confirms whether the GCS AS is authorized to receive the assigned TMGIs and assign it the requested TMGIs or the expiration time of the TMGIs of the extended request;

Step 3: The BM-SC returns an Allocation TMGI response message to the GCS AS, where the message includes the assigned TMGI list, TMGI expiration. The TMGI list identifies the assigned TMGI list, and the TMGI expiration identifies the expiration time for each assigned TMGI.

In the above process, the BM-SC assigns a TMGI to the group and sets a TMGI expiration time for each TMGI. If the corresponding TMGI is activated within the time specified by TMGI expiration time, the TMGI expiration time is automatically invalidated; if the corresponding TMGI has not been activated when the TMGI expiration time expires, the TMGI is released. In the above process, if the value of the parameter number of requested TMGIs in step 1 is 0, the function of the flow is that the GCS AS extends the TMGI expiration time for the pre-allocated TMGI request.

Currently, if the GCS AS wants to release the pre-allocated TMGI(s), the TMGI can be released by the TMGI de-allocation process as shown in Figure 3, including the following steps:

Step 1: The GCS AS sends a Deallocation TMGI request message to the BM-SC, and the parameters carried in the message include a list of TMGIs, which identifies the TMGI list to be allocated. If the parameter is not carried in the request message, it indicates that the GCS AS requests to allocate all pre-allocated TMGIs;

Step 2: The BM-SC confirms whether the GCS AS is authorized to request the allocated TMGIs, and allocates the TMGIs, and releases the MBMS resources corresponding to the TMGIs;

Step 3: The BM-SC returns a Deallocation TMGI response message to the GCS AS.

Currently, GCS AS can deactivate the process through the MBMS bearer shown in Figure 4. (Deactivate The MBMS Bearer Procedure is used to release the MBMS resource corresponding to the MBMS bearer, including the following steps:

Step 1: The MBMS bearer is being broadcasted inside the MBMS system;

Step 2: The GCS AS sends a Deactivate MBMS bearer request message to the BM-SC. The parameters carried in the message include a TMGI and a Flow ID. The TMGI and the Flow ID jointly identify a specific MBMS bearer; simultaneously release the corresponding MBMS bearer MBMS resources occupied in the MBMS system;

Step 4: The BM-SC returns a Deactivate MBMS bearer response message to the GCS AS, and the parameters carried in the message include TMGI and Flow ID.

It can be seen from the TMGI de-allocation process shown in Figure 3 that the BM-SC will also activate the MBMS bearer resources corresponding to the TMGI while releasing the TMGI, that is, in the TMGI de-allocation process, TMGI and MBMS. Bearer resources are always released together. It can be seen from the MBMS bearer deactivation process shown in FIG. 4 that after receiving the deactivation request message of the GCS AS, the BM-SC only activates the corresponding MBMS bearer resource, and how does the TMGI corresponding to the deactivated MBMS bearer Processing, no specific solution is given in the prior art. If all the MBMS bearers corresponding to the TMGI are released and the TMGI is still retained, the resource will be wasted. In addition, since the number of TMGIs allocated by the BM-SC is limited, if the unused TMGI is not released in time, Will affect the BM-SC to assign TMGI to other groups.

In summary, due to the existing MBMS bearer deactivation process, only the corresponding MBMS bearer resources are deactivated, which is likely to cause waste of TMGI resources. Summary of the invention

In the processing method and device of the TMGI provided by the present invention, after the GCS AS initiates the deactivation process of the last MBMS bearer corresponding to the same TMGI or all MBMS bearers of the same TMGI, the TMGI is released; the BM-SC completes the same TMGI After the corresponding last MBMS bearer or the deactivation process of all MBMS bearers of the same TMGI, the TMGI is released, thereby saving TMGI resources and improving the utilization of TMGI resources.

The invention is further described in detail below with reference to the accompanying drawings. It is to be understood that the embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to FIG. 5, a method for processing TMGI on the GCS AS side provided by the present invention is provided. Methods include:

Step 51: The GCS AS sends a first request message to the BM-SC, where the first request message is used to request to deactivate the last MBMS bearer of the TMGI or all MBMS resources corresponding to the MBMS bearer of the TMGI;

The same TMGI may correspond to multiple Flow IDs, and the TMGI and the different Flow IDs respectively identify different MBMS bearers. In this step, if the GCS AS requests to release the last MBMS bearer of the TMGI, the first request message carries the TMGI and the flow identifier Flow ID, where the Flow ID is used to identify the last MBMS bearer of the TMGI; if the GCS AS requests If all the MBMS bearers of the TMGI are released, the first request message carries the TMGI but does not carry the Flow ID, so that the first request message is used to request to release the MBMS resources corresponding to all the MBMS bearers of the TMGI.

Step 52: The GCS AS releases the TMGI.

In the embodiment of the present invention, the GCS AS sends a first request message to the BM-SC, where the first request message is used to request to deactivate the last MBMS bearer of the TMGI or the MBMS resource corresponding to all MBMS bearers of the TMGI; and the GCS The AS releases the TMGI. Since the GCS AS releases the TMGI after initiating the deactivation process of the last MBMS bearer corresponding to the same TMGI or all MBMS bearers of the same TMGI, the TMGI resource is saved, and the utilization of the TMGI resource is also improved.

In an implementation, in step 52, the GCS AS releases the TMGI, including the following two implementation methods:

1. When the last MBMS bearer of the TMGI or all the MBMS bearers of the TMGI are deactivated, the GCS AS does not release the TMGI immediately, and the TMGI is released when the set time condition is met;

2. The GCS AS immediately releases the TMGI when the last MBMS bearer of the TMGI or all MBMS bearers of the TMGI are deactivated.

Preferably, as a preferred implementation manner of the foregoing first implementation method, before the step 52, the method further includes: the GCS AS starting a first timer; Then, in step 52, the GCS AS releases the TMGI, including: after the first timer expires, the GCS AS releases the TMGI.

Preferably, the implementation of the first timer includes the following five manners:

Manner 1, the running time of the first timer is not greater than the running time of the second timer configured by the BM-SC for the TMGI.

In this manner, after the GCS AS sends the first request message, the method further includes: receiving, by the GCS AS, a first response message that is sent by the BM-SC to the first request message, and And determining, according to the running time of the second timer configured by the BM-SC in the first response message, the running time of the first timer.

In this manner, after completing the deactivation process of the last MBMS bearer of the TMGI or all MBMS bearers of the TMGI, the BM-SC configures a first timer (timer) for the TMGI, and the BM-SC and the GCS AS are configured according to the BM-SC and the GCS AS. The running time of the first timer determines whether to release the corresponding TMGI.

The following describes a method 1 for the interaction process between the GCS AS and the BM-SC in conjunction with a specific embodiment. Embodiment 1: In this embodiment, in the MBMS bearer deactivation process, if the deactivated MBMS bearer is the last MBMS bearer of the same TMGI or all bearers of the same TMGI, that is, the Flow ID identifier carried in the MBMS request message is deactivated. If the bearer is the last MBMS bearer corresponding to the same TMGI, or the deactivated MBMS request message does not carry the Flow ID, when the BM-SC receives the deactivated MBMS bearer request message (ie, the first request message) of the GCS AS, the BM- The SC releases the MBMS resource corresponding to the MBMS bearer, but does not release the TMGI, and the BM-SC configures the timer_1 for the TMGI corresponding to the deactivated MBMS bearer, and the timer is deactivated in the MBMS bearer response message (ie, the first response message). The running time of 1 is returned to the GCS AS, and the GCS AS locally starts the timer_2 for the TMGI. If the respective timers of the GCS AS and the BM-SC time out, the GCS AS and the BM-SC each release the TMGI locally.

The specific process is shown in Figure 6, which includes the following steps:

Step 1: The MBMS bearer is being broadcasted inside the MBMS system;

Step 2: The GCS AS sends a deactivated MBMS bearer request to the BM-SC (Deactivate MBMS) Bearer request ) message, which includes parameters TMGI and Flow ID;

Step 3: The BM-SC releases the corresponding MBMS to carry the MBMS resources occupied in the MBMS system. If the deactivated MBMS bearer of the Flow ID identifier carried in the MBMS request message is the last MBMS bearer or the deactivated MBMS request message of the same TMGI does not carry the Flow ID, the BM-SC starts the timer 1 for the corresponding TMGI; If timer-1 times out, the BM-SC releases the corresponding TMGI.

Step 4: The BM-SC returns a Deactivate MBMS bearer response message to the GCS AS, where the message carries the parameters TMGI, Flow ID, and timer information (that is, the running time of the timer 1). The timer information is an optional parameter. If the deactivated MBMS bearer identified by the Flow ID identifier carried in the MBMS request message is the last MBMS bearer of the same TMGI or the deactivated MBMS request message does not carry the Flow ID, the MBMS response is deactivated. The message includes the timer information.

Further, the GCS AS starts timer_2. If timer_2 times out, the GCS AS releases the TMGI locally. The running time of timer_2 is greater than the running time of timer-1 to ensure that the BM-SC and the GCS AS can simultaneously release the TMGI.

Mode 2. The running time of the first timer is configured by the GCS AS for the TMGI.

In this manner, before the sending, by the GCS AS, the first request message to the BM-SC, the method further includes:

If the GCS AS determines that the MBMS bearer requested to be deactivated by the first request message is the last MBMS bearer of the TMGI or all MBMS bearers of the TMGI, the GCS AS configures the first for the TMGI a timer, and carrying the running time of the first timer in the first request message.

This mode is similar to mode 1, except that the timer is started by the GCS AS for the TMGI. In the following, a mode 2 will be described from the interaction process between the GCS AS and the BM-SC in conjunction with a specific embodiment. Embodiment 2: In this embodiment, in the MBMS bearer deactivation process, if the deactivated MBMS bearer is the last MBMS bearer corresponding to the same TMGI or all MBMSs of the same TMGI The bearer, the GCS AS configures and starts timer_3 for the TMGI, and includes the timer information (that is, the runtime of the timer-3) in the deactivated MBMS bearer request message sent to the BM-SC; the BM-SC receives the deactivated MBMS bearer. After the message is requested, the MBMS resource corresponding to the corresponding MBMS bearer is released, and the timer-4 is configured and started for the corresponding TMGI. When timer-4 times out, the BM-SC releases the TMGI. The running time of timer_4 is less than the running time of timer_3.

The specific process is shown in Figure 7, which includes the following steps:

Step 1: The MBMS bearer is being broadcasted inside the MBMS system;

Step 2: The GCS AS sends a deactivated MBMS bearer request message to the BM-SC, where the message carries the parameters TMGI, Flow ID and timer information (that is, the running time of the timer-3).

The timer information is an optional parameter. When the MBMS bearer that is requested to be deactivated is the last MBMS bearer of the same TMGI or all the MBMS bearers of the same TMGI, the GCS AS configures the TMGI corresponding to the deactivated MBMS bearer and starts timer_3. .

In this embodiment, the deactivated MBMS bearer request is initiated for the last MBMS bearer of the same TMGI, and the GCS AS processes the TMGI corresponding to the timer-3 according to the set duration of the timer-3. Specifically: if timer_3 times out, the GCS AS releases the corresponding TMGI;

Step 3: After the BM-SC receives the deactivated MBMS bearer request message, the BM-SC releases the MBMS resource that the MBMS bears in the MBMS system, saves the timer-3 information, and starts the timer_4.

When timer-4 times out, the BM-SC releases the corresponding TMGI. The running time of the timer-3 is greater than the running time of the timer-4 to ensure that the BM-SC and the GCS AS can release the TMGL at the same time.

In the implementation, if the timer information is not included in the step 2, the BM-SC starts a default timer for the corresponding TMGI, that is, the technical solution of the first embodiment.

Step 4: After releasing the MBMS resource occupied by the corresponding MBMS in the MBMS system, the BM-SC returns a deactivated MBMS bearer response to the GCS AS.

Manner 3: The running time of the first timer is a duration of time that the BM-SC is a new valid time determined by the TMGI. In this manner, after the GCS AS sends the first request message, the method further includes: receiving, by the GCS AS, a first response message that is sent by the BM-SC to the first request message, where The first response message includes a new valid time determined by the BM-SC for the TMGI, and the duration of the new valid time is determined as the running duration of the first timer.

Mode 3: Decide whether to release the TMGI by determining a new expiration time for the TMGI.

In this manner, after step 51, the method further includes:

Receiving, by the GCS AS, a first response message to the first request message returned by the BM-SC, if the first response message includes a new valid time determined by the BM-SC for the TMGI, the GCS AS starts the new response message. Effective time.

The following describes a method 3 for the interaction process between the GCS AS and the BM-SC in conjunction with a specific embodiment. Embodiment 3: In this embodiment, in the MBMS bearer deactivation process, if the deactivated MBMS bearer is the last MBMS bearer corresponding to the same TMGI or all MBMS bearers of the same TMGI, then the BM-SC receives the GCS AS. After the MBMS bearer request message is activated, the BM-SC releases the MBMS resource corresponding to the corresponding MBMS bearer, but does not release the TMGI, and determines a new expiration time for the TMGI corresponding to the MBMS bearer, and includes the new expiration time information in the deactivation. The MBMS bearer response message is returned to the GCS AS. The specific process is shown in Figure 8, which includes the following steps:

Step 1: The MBMS bearer is being broadcasted inside the MBMS system;

Step 2: The GCS AS sends a deactivated MBMS bearer request message to the BM-SC, where the message carries the parameter TMGI and Flow ID;

Step 3: The BM-SC releases the MBMS resource occupied by the corresponding MBMS in the MBMS system. If the deactivated MBMS carried by the Flow ID identifier carried in the deactivated MBMS request message is the last MBMS of the same TMGI, it is deactivated or deactivated. The MBMS request message does not carry the Flow ID, and the BM-SC does not release the TMGI, and determines a new expiration time for the TMGI;

Step 4: The BM-SC returns a deactivated MBMS bearer response message to the GCS AS, where the message is Includes parameters TMGI, Flow ID and new TMGI expiration. The new TMGI expiration identifies the new expiration time determined by the BM-SC for the TMGI.

Further, after receiving the deactivated MBMS bearer response message, the GCS AS saves the new expiration time. TMGI is valid during the new expiration time, and the specific mechanism is the same as the prior art, and will not be described here.

Mode 4: The running time of the first timer is a duration of the validity time determined by the BM-SC in the TMGI allocation process.

In this manner, after the GCS AS sends the first request message, the method further includes: receiving, by the GCS AS, a first response message that is sent by the BM-SC to the first request message, if Determining, by the GCS AS, that the MBMS bearer requested to be deactivated by the first request message is the last MBMS bearer of the TMGI or all MBMS bearers of the TMGI, and the GCS AS allocates the BM in the TMGI allocation process The duration of the effective time determined by the SC for the TMGI is determined as the running time of the first timer.

In this manner, whether to release the TMGI is determined by restarting the expiration time determined by the BM-SC in the TMGI allocation process for the TMGI.

Manner 5: The running time of the first timer is a duration of time when the BM-SC is extended by the TMGI.

In this manner, after the GCS AS sends the first request message, the method further includes: receiving, by the GCS AS, a first response message that is sent by the BM-SC to the first request message, if Determining, by the GCS AS, that the MBMS bearer requested to be deactivated by the first request message is the last MBMS bearer of the TMGI or all MBMS bearers of the TMGI, and the GCS AS initiates the set number of times to the BM-SC a request for extending the validity time of the TMGI, wherein a running time of the first timer is a sum of valid times of the TMGI extended by the set number of requests;

Sending, by the GCS AS, a second request for requesting to allocate the TMGI to the BM-SC a message; and receiving a second response message to the second request message returned by the BM-SC. This method applies to extend the validity time of TMGI by initiating the TMGI distribution process. Specifically: the GCS AS receives the first response message that is returned by the BM-SC to the first request message, and if the GCS AS determines that the MBMS bearer requested to be deactivated is the last MBMS bearer of the TMGI or the TMGI All the MBMS bearers, the GCS AS sends a second request message for requesting to extend the validity time of the TMGI to the BM-SC; the GCS AS receives the second response message returned by the BM-SC to the second request message, The second response message carries the extended effective time determined by the BM-SC for the TMGI; if the GCS AS does not use the TMGI within the effective time after the extension, it is valid after exceeding the extension. At the time, the GCS AS re-initiates the process of extending the validity of the TMGI. If the number of times the GCS AS initiates the process of extending the validity time of the TMGI exceeds the set number of repetitions, and the GCS AS does not use the TMGI within any valid time after the extension, the validity is exceeded after the last extension. After the time, the GCS AS sends a third request message for requesting to allocate the TMGI to the BM-SC, and after receiving the third response message to the third request message returned by the BM-SC, releasing the TMGI.

In this manner, the number of repetitions of the repeated initiation of the TMGI allocation process may be configured by the GCS AS, or may be configured by the BM-SC and notified to the GCS AS, and may also be determined by the GCS AS and the BM-SC, and the present invention does not implement the implementation manner. limited.

Preferably, as a preferred implementation of the foregoing second implementation method, the following two manners are provided: Method 6. Determine whether to release the TMGI by carrying the indication information in the first request message. In this manner, before the GCS AS releases the TMGI, the GCS AS further includes:

If the GCS AS determines that the MBMS bearer requested to be deactivated by the first request message is the last MBMS bearer of the TMGI or all MBMS bearers of the TMGI, the GCS AS carries in the first request message Instructing the BM-SC to release the indication information of the TMGI when completing the last MBMS bearer of the TMGI or deactivating all MBMS bearers of the TMGI;

The GCS AS receives a first response message to the first request message returned by the BM-SC. Of course, the present invention is not limited to including indication information in the deactivated MBMS bearer request initiated for the last MBMS bearer of the TMGI or all MBMS bearers of the TMGI, and may also be in the first MBMS bearer for the TMGI. The indication information is included in the initiated deactivated MBMS bearer request. Specifically:

When the first request message is sent to the BM-SC for the first MBMS bearer of the TMGI, the GCS AS carries the first MBMS bearer or the BM-SC to indicate the completion of the TMGI in the first request message. Whether the indication information of the TMGI is released when all MBMS bearers of the TMGI are deactivated.

In this mode, the GCS AS immediately releases the TMGI after receiving the first response message returned by the BM-SC.

The manner of interaction between the GCS AS and the BM-SC will be described below in conjunction with a specific embodiment. Embodiment 4: In this embodiment, in the MBMS bearer deactivation process, if the deactivated MBMS bearer is the last MBMS bearer corresponding to the same TMGI or all MBMS bearers of the same TMGI, the GCS AS adds the deactivated MBMS bearer request message. A new indicator is used to indicate whether the BM-SC releases the corresponding TMGI when deactivating the last MBMS bearer or all MBMS bearers of the same TMGI. After receiving the MBMS bearer request message from the GCS AS, the BM-SC processes the corresponding TMGI according to the indication of the Indicator. The specific process is shown in Figure 9, which includes the following steps:

Step 1: The MBMS bearer is being broadcasted inside the MBMS system;

Step 2: The GCS AS sends a deactivated MBMS bearer request message to the BM-SC, where the message carries the parameters TMGI, Flow ID and Indicator.

The indicator is an optional parameter. If the GCS AS determines that the MBMS bearer requested to be deactivated is the last MBMS bearer of the same TMGI or all MBMS bearers of the same TMGI, the GCS AS includes an Indicator parameter in the message, which is used to Indicates whether the BM-SC releases the corresponding TMGI immediately.

Step 3: The BM-SC releases the MBMS resource occupied by the corresponding MBMS in the MBMS system, and according to the received Indicator indication, determines that the MBMS corresponding to the MBMS bearer is released. Whether the corresponding TMGI is released immediately at the same time as the resource;

Preferably, the value of the above indicator may be 0 or 1, where 0 means deactivating the last MBMS bearer of the same TMGI or deactivating all MBMS bearers of the same TMGI, and immediately releasing the corresponding TMGI; 1 means deactivating the same TMGI After the last MBMS bears or deactivates all MBMS bearers of the same TMGI, the corresponding TMGI is retained.

Step 4: The BM-SC returns a deactivated MBMS bearer response message to the GCS AS, where the message carries the parameters TMGI and Flow ID.

Method 7: Release the corresponding TMGI by initiating the allocation of the TMGI process.

In this manner, after step 51, and before step 52, the method further includes:

Receiving, by the GCS AS, the first response message to the first request message returned by the BM-SC, if the GCS AS determines that the MBMS bearer requested to be deactivated by the first request message is the last of the TMGI An MBMS bearer or all MBMS bearers of the TMGI, the GCS AS sending a second request message to the BM-SC for requesting to allocate the TMGI;
