Problems solved by technology

Such a situation occurs in multiple terminals, which will inevitably lead to an increase in the load of the above-mentioned fully configured carrier
If according to the signaling instruction, the multicast broadcast service that the terminal is interested in configures the carrier in another part, the base station needs to update the secondary carrier for the terminal first, which increases the signaling overhead between the base station and the terminal

Embodiment 1

[0065] This embodiment is described by taking the action start time carried in the service flow establishment message as an example.

[0066] A terminal A first transmits data on carrier 1, then performs carrier conversion, and then receives data on carrier 2, where carrier 1 is the fully configured carrier and the main carrier of the terminal A, and carrier 2 is the partially configured carrier for the terminal A the auxiliary carrier. Such as figure 1 As shown, the method includes:

[0067] Step 101, the base station sends a service flow establishment response message (AAI-DSA-RSP) to terminal A on carrier 1, and establishes a multicast broadcast service flow for terminal A;

[0068] The base station learns in advance the multicast broadcast service that the terminal is interested in through the upper layer signaling interaction with the terminal, so as to initiate the process of establishing the multicast broadcast service flow.

[0069]In other embodiments, the base sta...

Embodiment 2

[0085] This embodiment is described by taking the action start time carried in the service flow establishment message as an example.

[0086] A terminal A first transmits data on carrier 1, and then performs carrier switching to carrier 2 for data reception. Carrier 1 is the fully configured carrier and the main carrier of the terminal A, and carrier 2 is the partially configured carrier for the terminal A. secondary carrier. Such as figure 2 As shown, the method includes:

[0087] Step 201, the base station sends an AAI-DSA-RSP message (or AAI-DSA-REQ message) to terminal A on carrier 1, and establishes a multicast broadcast service flow for terminal A;

[0088] The AAI-DSA-RSP message (or AAI-DSA-REQ message) carries the carrier identification information carrying the multicast broadcast service flow, but if the established service flow is located on the current carrier, the AAI-DSA-RSP message (or The AAI-DSA-REQ message) may also not carry carrier identification inform...

Embodiment 3

[0107] This embodiment is described by taking the action start time carried in the service flow establishment message as an example.

[0108] A terminal A first transmits data on carrier 1, and then performs carrier switching to carrier 2 for data reception. Carrier 1 is the fully configured carrier and the main carrier of the terminal A, and carrier 2 is the partially configured carrier for the terminal A. secondary carrier. Such as image 3 As shown, the method includes:

[0109] Step 301, the base station sends an AAI-DSA-RSP message (or AAI-DSA-REQ message) to terminal A on carrier 1, and establishes a multicast broadcast service flow for terminal A;

[0110] The AAI-DSA-RSP message (or AAI-DSA-REQ message) carries the carrier identification information carrying the multicast broadcast service flow, but if the established service flow is located on the current carrier, the AAI-DSA-RSP message (or The AAI-DSA-REQ message) may not carry carrier identification information....

Abstract

The invention discloses a method, a terminal and a system for receiving a multicast broadcasting service, which solve the problem that the load of part of carriers is increased, and reduce complexity of terminal operation and signaling expenditure of the system. The method for receiving the multicast broadcasting service comprises the following step that: the terminal is switched to a carrier M bearing the multicast broadcasting service actively or according to command information sent by a base station to receive a multicast broadcasting service stream in the process of receiving the multicast broadcasting service.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method, terminal and system for receiving multicast broadcast services. Background technique [0002] A wireless communication system provides wireless coverage within a certain geographical range through a base station (Base Station, BS for short) using a designated wireless communication channel, and this geographical range is called a cell. Due to the rapid development of communication technology, an advanced base station (Advanced BS, referred to as ABS) appears. The advanced base station can support traditional terminals compatiblely. Similarly, the traditional base station can also support advanced terminals (Advanced Mobile Station, referred to as AMS). For example, an advanced base station supporting the Institute for Electrical and Electronic Engineers (Institute for Electrical and Electronic Engineers, IEEE) 802.16m protocol can be compatible with a terminal support...
