Problems solved by technology

According to normal processing, if the MBMS UE context of the corresponding UE is updated in the GGSN, then the UE can be charged. However, if the current SGSN of the corresponding UE has not registered in the corresponding GGSN at this time, the UE will The corresponding MBMS multicast data cannot be obtained, which will lead to billing errors for the user, resulting in a decline in user satisfaction and affecting the reputation of the operator

Embodiment 1

[0065] In this embodiment, the registration of the new SGSN on the corresponding GGSN is placed between step 306 and step 307 in the processing flow of routing area update in the prior art. In this embodiment, the processing procedure of the routing area update in the MBMS service is as shown in Figure 4, including the following steps:

[0066] Step 401: After a certain UE activates the MBMS bearer service, it sends a routing area update request message Routing Area Update Request to the new SGSN via the radio access network (RAN);

[0067] Step 402: After the new SGSN receives the routing area update request, it sends the SGSN context request message SGSN Context Request to the original SGSN to obtain the MM context, PDP context and MBMS UE context of the UE; after the original SGSN receives the SGSN context request, Return the SGSN Context Response message carrying the corresponding context of the specified UE to the new SGSN; here, the original SGSN may return the MBMS UE c...

Embodiment 2

[0083] In this embodiment, the registration of the new SGSN on the corresponding GGSN is placed between step 304 and step 306 in the processing flow of routing area update in the prior art. In this embodiment, the processing procedure of the routing area update in the MBMS service is as shown in Figure 5, including the following steps:

[0084] Steps 501-504: are identical to all descriptions of steps 401-404 in Embodiment 1.

[0085] Step 505: The new SGSN verifies whether each received MBMS UE context has a corresponding MBMS bearer context; if the new SGSN does not have a corresponding MBMS bearer context, then the new SGSN creates an MBMS bearer context, and sets the created MBMS bearer context to Stand by, and send the MBMS Registration Request to the corresponding GGSN; the GGSN returns the MBMS Registration Response to the new SGSN; if the new SGSN has a corresponding MBMS bearer context, this step is not performed;

[0086] Steps 506-507: are exactly the same as all d...

Embodiment 3

[0090] In this embodiment, the registration of the new SGSN on the corresponding GGSN is placed between step 306 and step 307 in the prior art routing area update processing flow; and, while the original SGSN deletes the MM context and PDP context of the current UE , delete the MBMS UE context. Specifically, in this embodiment, step 410 in Embodiment 1 is changed to step 410'.

[0091] Step 410': HLR sends a location cancellation message Cancel Location to the original SGSN, and the original SGSN deletes the MM context, PDP context and all MBMS UE contexts of the UE after receiving it, and the original SGSN returns the location cancellation confirmation message Cancel Location Ack to the HLR. Specifically, how the original SGSN deletes the relevant context is the same as that of the prior art.

Abstract

The method includes steps: (1) after current UE sends request for updating routing area to new SGSN, new SGSN obtains relevant context information of current UE from former SGSN; new SGSN determines whether self registers MBMS bearer service corresponding to context of current obtained MBMS UE on relevant GGSN already; if yes, executing step (2); otherwise, new SGSN carries out registration on relevant GGSN first, then executes step (2); (2) New SGSN and corresponding GGSN update MBMS UE context of current UE in interaction, and accomplish updating data information relevant to current UE in HLR. The method prevents improper charging from occurring effectively, providing better service for users.

Description

technical field [0001] The invention relates to routing updating technology, especially a method for updating routing area in Multimedia Broadcast / Multicast Service (MBMS) service. Background technique [0002] With the development of the third-generation mobile communication technology, the third-generation mobile communication can provide services with a higher data rate than the second-generation mobile communication, thereby supporting various business forms. Services such as video calls, picture downloads, and high-speed Internet browsing. One of the characteristics of one type of service is that the service can be sent to users who have subscribed to the service in the wireless network at the same time. For example, weather forecasts, news clips, sports highlights and so on. Taking advantage of the simultaneous transmission of these services, the third-generation mobile communication introduces the concept of broadcast / multicast. [0003] As shown in Figure 1, for a...
