Problems solved by technology

[0029] from image 3 It can be seen from the shown session start procedure in the existing MBMS that the existing session start procedure is designed for the GPRS / UMTS system and is aimed at figure 1 The shown GERAN / UTRAN and SGSN-GGSN architecture is carried out, the considered access network is GERAN or UTRAN, and WLAN is not considered as the access network. Therefore, the MBMS session start process has not yet been provided under the I-WLAN framework

Embodiment 1

[0088] Figure 7 It is a flow chart of the first embodiment of session initiation in the present invention, such as Figure 7 As shown, in this embodiment, there are four pairs of nodes that are upstream nodes and downstream nodes: BM-SC and AAA server, AAA server and PDG, AAA server and WAG, and AAA server and WLAN AN. In this embodiment, the upstream node sends the session attribute to the downstream node through the session start request message, and the BM-SC initiates the session start request message through the AAA server, specifically including the following steps:

[0089] Step 701 - Step 702: BM-SC sends a session start request (Session Start Request) message to its downstream node AAA server, indicating the upcoming data transmission and providing the first session attribute. The session start request message is sent to all AAA servers in the "downstream node list" parameter in the MBMS bearer context. The AAA server stores the received first session attribute loc...

Embodiment 2

[0102] Figure 8 It is the flow chart of the second embodiment of session initiation in the present invention, such as Figure 8 As shown, in this embodiment, there are three pairs of nodes that are upstream nodes and downstream nodes: BM-SC and PDG, PDG and WAG through AAA server, PDG and WAG through AAA server, and PDG and WLANAN through AAA server. In this embodiment, the upstream node sends the session attribute to the downstream node through the session start request message, the BM-SC initiates the session start request message through the PDG and the PDG sends the session start request message to the WAG and the WLAN AN through the AAA server, specifically including the following steps :

[0103] Steps 801 to 802: the BM-SC sends a session start request message to its own downstream node PDG, indicating the upcoming data transmission and providing the first session attribute. The session start request message is sent to all PDGs in the "downstream node list" parameter...

Embodiment 3

[0112] Figure 9 It is the flow chart of the third embodiment of the session start of the present invention, such as Figure 9 As shown, in this embodiment, there are four pairs of nodes that are upstream nodes and downstream nodes: BM-SC and AAA server, AAA server and PDG, PDG and WAG, and WAG and WLAN AN. In this embodiment, the upstream node sends the session attribute to the downstream node through the session start request message, and the BM-SC sends the session start request message step by step through the AAA server, specifically including the following steps:

[0113] Steps 901 to 902: BM-SC sends a session start request message to its own downstream node AAA server, indicating upcoming data transmission and providing session attributes. The session start request message is sent to all AAA servers in the "downstream node list" parameter in the MBMS bearer context. The AAA server stores the received first session attribute locally, and returns a session start respon...

Abstract

This invention discloses a method for starting dialogs in MBMS, in which, in the I-WLAN, the upper reach node processing the MBMS service sends a dialog attribute to the lower reach node in the relationship of mutual upper and lower reach nodes, the lower reach node stores the received attribute to control the session in the process. This invention provides a dialog start flow in the MBMS in the I-WLAN and provides multiple modes.

Description

technical field [0001] The present invention relates to multimedia broadcasting / broadcasting technology, especially a kind of method based on interworking wireless local area network (I-WLAN, Interworking Wireless Local Area Network), realizes the session start in multimedia broadcasting / multicasting service (MBMS, Multimedia Broadcast / Multicast 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, such as video calls, picture downloads, and high-speed Internet browsing. Serve. 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, such as weather forecast, news clips, sports game highlights and so on. Taking advantage of ...
