specific Embodiment approach

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] The invention proposes a method for recovering and rebuilding the abnormally released MBMS service on RNC or BSC. Such as image 3 As shown in , when the RNC or BSC releases the corresponding MBMS resources abnormally due to the internal failure of the RNC or BSC, or the transmission failure between the RNC or BSC and the SGSN, and the SGSN releases the MBMS resources related to the RNC or BSC abnormally, the SGSN The released MBMS service on the RNC or BSC is recovered by reinitiating the MBMS session start procedure to the RNC or BSC that has released the MBMS resources abnormally.

Embodiment 1

[0037] Embodiment one: (reference figure 2 and Figure 4 )

[0038] The MBMS sessions of MBMS services A and B have been established between RNC1 and SGSN1. After RNC1 releases the MBMS session of service A abnormally, a resource reset process is triggered. Specific steps are as follows:

[0039] Step 410, RNC1 detects that the MBMS Iu signaling connection corresponding to MBMS service A is interrupted, locally releases the MBMS resources of service A, including MBMS Iu signaling connection and Iu signaling connection identifier, or also includes MBMS RAB, and sends a reset resource to SGSN1 Message (RESETRESOURCE), which contains the Iu signaling connection identifier corresponding to the released MBMS Iu signaling connection, which is allocated by SGSN1 when the MBMS service A session is established and passed through the MBMS session start request message (MBMS Session Start Request) Bring to RNC1;

[0040] Step 420, after receiving the reset resource message of RNC1,...

Embodiment 2

[0044] Embodiment two: (reference figure 2 and Figure 5 )

[0045] BSC1 and SGSN1 establish MBMS sessions of MBMS services A, B, and C, and BSC1 initiates a reset process to SGSN1 after power-off and restart. Specific steps are as follows:

[0046] Step 510, BSC1 sends a reset message RESET to SGSN1 after power-off and restart, so that the resources of BSC and SGSN are consistent;

[0047] Step 520, after receiving the reset message from BSC1, SGSN1 releases all MBMS resources related to BSC1, that is, the MBMS resources of MBMS services A, B, and C, and returns a reset confirmation message (RESET ACKNOWLEDGE) to BSC1;

[0048] In step 530, SGSN1 initiates the session initiation procedures of MBMS services A, B and C respectively to BSC1.

[0049] Re-establish the MBMS session bearers of services A, B, and C between SGSN1 and BSC1, and each corresponding MBMS session start request message includes the Iu signaling connection identifier redistributed by SGSN1; BSC1 recei...

Abstract

The invention discloses a recovery method of a multimedia broadcasting multicast service, which rebuilds a released MBMS service between an SGSN and an RNC / BSC, ensures that a UE under the RNC / BSC receives the corresponding MBMS service, ensures normal MBMS service control between the SGSN and RNC or BSC. A network element includes the SGSN, the RNC or BSC, when the RNC or BSC abnormally releasesMBMS sources and triggers SGSN to release MBMS sources related to the RNC or BSC, alternatively, after the SGSN abnormally releases the MBMS sources related to the RNC or BSC and triggers the RNC or BSC to release the related MBMS sources, the SGSN initiates an MBMS conversation start process again to the RNC or BSC.

Description

technical field [0001] The invention relates to MBMS in a mobile communication system, in particular to a recovery method for abnormally released MBMS services on RNC or BSC. Background technique [0002] With the popularization of large-screen multifunctional mobile phones, the application of mobile data services is becoming more and more extensive. The demand for mobile communications is no longer satisfied with phone calls, messaging and mobile Internet browsing services. The Generation Partnership Project, the third generation partner project) proposed MBMS (Multimedia Broadcast / Multicast Service, Multimedia Broadcast Multicast Service), which provides a point-to-multipoint service in which a data source sends data to multiple users in a mobile network, and realizes Network resource sharing improves the utilization of network resources, especially the precious air interface resources. MBMS service is a technology that shares network resources to transmit data from one d...
