Embodiment 1

[0162] Fig. 6 is the flow chart of the specific embodiment 1 of multicast service activation provided by the present invention, as shown in Fig. 6, its specific steps are as follows:

[0163]Step 601: An MBMS service tunnel is established between the UE and the PDG through a tunnel establishment request / response message, and the UE and the PDG store the established tunnel identifier.

[0164] The tunnel may be a dedicated tunnel that only supports MBMS service transmission, or a general tunnel that supports both MBMS service transmission and other service transmissions.

[0165] Step 602: The UE initiates a multicast service joining message carrying its own identity to the PDG.

[0166] The multicast service join message may be an IGMP message defined by IPv4, or an MLD protocol message defined by IPv6, or a message carried by SIP, HTTP, WAP, or a custom protocol.

[0167] The multicast service joining message may or may not carry the multicast service identifier. Multicast ...

Embodiment 2

[0189] Fig. 7 is the flow chart of the specific embodiment 2 of multicast service activation provided by the present invention, as shown in Fig. 7, the flow shown in this figure is compared with the flow shown in Fig. 6:

[0190] Steps 701-702 are the same as steps 601-602.

[0191] The difference between step 703 and step 603 is that after receiving the multicast service join message, the PDG first sends the MBMS authorization request message to the AAA server, and then the AAA server forwards the MBMS authorization request message to the BM-SC.

[0192] The Wm interface defined in 3GPP TS 23.234 can be enhanced such as: make the interface support the transmission of authorization request / response messages and corresponding parameters, etc., and use the enhanced Wm interface as the interface between the PDG and the AAA server. The interface protocol can be Adopt the Diameter protocol.

[0193] The difference between step 704 and step 604 is: after receiving the MBMS authoriz...

Embodiment 3

[0202] Fig. 8 is a flow chart of the third embodiment of multicast service activation provided by the present invention. As shown in Fig. 8, the flow shown in this figure is compared with the flow shown in Fig. 6:

[0203] Steps 801-603 are the same as steps 601-603.

[0204] The difference between step 804 and step 604 is that: the authorization response message returned by the BM-SC to the PDG indicating that the authorization is successful further carries a W-APN, and the W-APN points to PDG2; and in step 804, the BM-SC does not create an MBMS UE context .

[0205] When the BM-SC receives MBMS authorization request messages for the same multicast service from multiple PDGs at the same time, for convenience, the BM-SC will designate one of the multiple PDGs to perform the subsequent service activation process, and send the The W-APN corresponding to the designated PDG is returned to other PDGs except the designated PDG.

[0206] The difference between step 805 and step 605 i...

Abstract

The method comprises: adding communication interface between PDG and BM-SC, and sending the request of enabling the multicast service to PDG in order to inform that the PDG itself wants to participate the multicast service; the PDG sends MBMS authorization request to BM-SC; after BM-SC receives the MBMS authorization request, it put the success or failure message of authorization into the MBMS authorization response message that is returned to the PDG; after PDG receives the MBMS authorization response message, if detecting the success authorization indication from the MBMS authorization response message, it sends the multicast service enable acceptance message; otherwise, it send the multicast service reject enable message to UE. The invention implements the enable of IWLAM-based multicast service.

Description

technical field [0001] The invention relates to the technical field of service activation, in particular to a method for activating multicast services under the framework of an interworking wireless local area network. Background technique [0002] With the development of mobile communication technology, the third-generation mobile communication can provide higher-speed data services than the second-generation mobile communication, thereby supporting various business forms, such as providing video calls, picture downloads, high-speed Internet browsing and other services. , and one of them is characterized by the fact that this type of service can be sent to all users who have subscribed to this type of service in the wireless network at the same time, such as: weather forecast, news clips, sports game highlights, etc. Taking advantage of the fact that this type of service can be sent at the same time, the third generation mobile communication system introduced the concept of...
