Problems solved by technology

[0017] The first technical solution, for service continuity, only provides power-saving support when the terminal moves within the multicast broadcast service area, but once the terminal moves to other multicast broadcast service areas, there is no corresponding power-saving support, and the terminal may Network re-entry is required to restore the receiving service. The service interruption time is too long, and it is not conducive to the power saving of the terminal, which will seriously affect the user experience; and the second technical solution, for the case where the terminal moves to a new multicast broadcast service area, Only the air interface solution is provided, and there is no corresponding solution on the network side at present, which does not constitute a complete technical solution and cannot be applied

Embodiment 1

[0182] Embodiment 1 (corresponding operation selection 1):

[0183] The terminal that subscribes to the MCBCS service moves to a new MBS Zone (the anchor paging controller has not changed), and the location update operation is as follows: figure 1 shown.

[0184] 1. The terminal sends an RNG request, including corresponding multicast broadcast service information.

[0185] 2. The serving access network sends a location update request message, and forwards the corresponding multicast broadcast service information to the anchor paging controller. Note: This message may reach the access network where the anchor paging controller is located via several intermediate access networks.

[0186] 3. The anchor paging controller will initiate an MBS area update request to the current serving MBS agent to obtain a new multicast connection ID and multicast broadcast area ID, and if possible, a new serving MBS agent and a new anchor MBS data channel function body and other related inform...

Embodiment 2

[0192] Embodiment 2 (corresponding to operation selection 2)

[0193] Such as Figure 4 shown, including:

[0194] 1. The terminal sends a RNG_REQ message to initiate a location update process, which includes an MBS update indication, indicating that the terminal detects that the MBS area it is in has changed;

[0195] 2. The current serving base station sends a location update request message to the current access gateway. According to the present invention, the message should include the MBS update instruction and the MBS area related information supported by the current base station (MBS area identification, corresponding MBS service identification and multicast connection identification);

[0196] 3. The current access gateway sends a location update request message to the anchor paging controller access network corresponding to the terminal. According to the present invention, the message should include the MBS update instruction and the MBS area related information su...

Embodiment 3

[0203] Embodiment three (corresponding operation selection three)

[0204] Refer to the accompanying drawings of the second embodiment above, including:

[0205] 1. The terminal sends a RNG_REQ message to initiate a location update process, which includes an MBS update indication, indicating that the terminal detects that the MBS area it is in has changed;

[0206] 2. The current serving base station sends a location update request message to the current access gateway. According to the present invention, the message should contain an MBS update indication;

[0207] 3. The current access gateway sends a location update request message to the anchor paging controller access network corresponding to the terminal. According to the present invention, the message should contain an MBS update indication;

[0208] 4. The anchor paging controller access network acquires authentication context information;

[0209] 5. The anchor paging controller access network sends a location upd...

Abstract

The invention discloses a method for a terminal to maintain service continuity between multicast broadcast service areas. When moving to a novel multicast broadcast service area, the terminal still maintains the continuity of a multicast broadcast service. The method comprises the following steps: determining multicast broadcast service information corresponding to the terminal in the process that the terminal initiates position updating or exits an idle mode according to prestored context information of a multicast broadcast service of the terminal and multicast broadcast service information of the current multicast broadcast service area of the terminal, wherein the multicast broadcast service information corresponding to the terminal at least comprises a multicast connection identifier and a multicast broadcast service area identifier; and transmitting the multicast broadcast service information to the terminal.

Description

technical field [0001] The invention relates to the field of multicast and broadcast services, in particular to a method for a terminal to maintain service continuity between multicast and broadcast service areas. Background technique [0002] In the multicast broadcast service, according to the existing IEEE 802.16 protocol, the terminal can continuously receive the downlink transmission content of the multicast broadcast service (MCBCS or MBS) in the multicast broadcast area, and can continue to receive in sleep or idle mode. No matter what operation mode the terminal is in (i.e. active state, sleep mode or idle mode), or what kind of multicast broadcast service type (i.e. broadcast or multicast), the network will continue to send the current multicast broadcast service Downstream content. [0003] In order to support the MCBCS operation of the multicast broadcast service in the access service network (ASN), the multicast broadcast service synchronization controller will ...
