Problems solved by technology

[0005] 1) Each user must give feedback or make a request, reflecting that he cannot receive BCMCS services;
[0006] 2) Network administrators must perform manual operations for each user each time;
[0007] 3) Clearing existing sessions causes the user to disconnect and reconnect from the EVDO data network with a noticeable time lag

no. 1 approach

[0022] In this embodiment, the access terminal AT supporting broadcast and multicast services accesses the base station BS1 under the jurisdiction of the radio network controller RNC supporting broadcast and multicast services, but the accessed base station BS1 or the accessed The sectors of base station BS1 do not support broadcast multicast services. For example, the access terminal AT is just powered on, and first performs session setting and UATI (Unicast Access Terminal Identifier, single-channel access terminal identifier) ​​allocation with the radio network controller RNC, and the access terminal AT is uniquely identified by the UATI.

[0023] Afterwards, preferably, regardless of whether the access terminal AT and the base station BS1 currently accessed by the input terminal AT support broadcast and multicast services, such as figure 1 As shown, in step S10, the radio network controller RNC forcibly sends a configuration request for the broadcast protocol to the access...

no. 2 approach

[0035] In this embodiment, the access terminal AT is handed over from another radio network controller RNC' to the management of the radio network controller RNC. The RNC' may or may not have the BCMCS function.

[0036] like figure 2 As shown, firstly, the access terminal AT needs to complete operations required for roaming handover, such as routing update and UATI allocation, with the radio network controller RNC. For example, the access terminal AT sends routing updates and UATI requests to the RNC.

[0037] Next, in step S20, the radio network controller RNC acquires the session information corresponding to the access terminal AT from the other radio network controller RNC' through, for example, the A13 radio interface. For example, RNC sends A13 session information request to RNC '; RNC ' feeds back A13 session information response with session information to RNC; RNC sends A13 session information confirmation to RNC '. The session information records the currently ne...

Abstract

The invention provides a method for supporting a broadcast multicast service of an access terminal in base station control equipment, and aims at the shortcoming that an access network cannot normally provide the broadcast multicast service for the conventional access terminal in the intra-radio network controller (RNC) and inter-RNC switching of the access terminal. For the intra-RNC switching, when a sector carrier of a base station currently accessed by the access terminal does not support the broadcast multicast service, an RNC still negotiates with the access terminal about the configuration attribute of the broadcast multicast service; and for the inter-RNC switching, the RNC determines that negotiation with the access terminal about a broadcast multicast service protocol and the configuration attribute or about the configuration attribute is required according to the previous session information of the access terminal. Therefore, the RNC can provide the service for the access terminal in regions with broadcast multicast service provision capability within a range administrated by the RNC.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to wireless broadcast multicast service. Background technique [0002] Among the EVDO (Evolution-Data Optimized, or Evolution-Data only) technologies adopted by many operators worldwide, Broadcast Multicast Service (BCMCS) is a It is an important service that can provide broadcast and multicast service data to access terminals such as mobile phones or EVDO modems. But at present, not all service areas support the provision of broadcast and multicast services. In addition, each service area may be governed by base station control equipment (such as a radio network controller, Radio Network Controller, RNC for short) provided by different manufacturers, and these equipments have not yet unified the way of providing broadcast and multicast services. Therefore, according to the current actual network test, when a user roams or switches from an area that does not support BCM...
