Problems solved by technology

However, at present, MBMS uses existing WCDMA resources, that is, existing transmission channels and physical channels, which result in occupying a large amount of existing wireless resources
In this way, there are two impacts: on the one hand, other existing services will be greatly affected; on the other hand, the types of services that MBMS services can provide at the same time are greatly limited

Embodiment 1

[0086] In this embodiment, only MBMS carriers are used to transmit MBMS services, and other interactive operations are completed on non-MBMS carriers.

[0087] The method of the present invention adopting a separate carrier to carry MBMS services actually includes two parallel processes: the MBMS service sending process on the UTRAN side and the MBMS service receiving process on the UE side.

[0088] From the perspective of UTRAN, the sending process of MBMS service is as follows: Figure 11 The following steps are shown:

[0089] Steps 1101-1102: The network selects a dedicated frequency segment as an MBMS carrier for transmitting MBMS services, and notifies the UE of the selected MBMS carrier information.

[0090] Here, the network generally selects appropriate frequency bands to allocate to MBMS services individually according to the needs of operators; it can be selected at any time before the start of MBMS services, or can be selected during network planning according to...

Embodiment 2

[0120] In this embodiment, the UTRAN uses the MBMS carrier to send counting related indication information, and performs counting on the MBMS service on the MBMS carrier, then step 1104 becomes step 1104':

[0121] Step 1104': UTRAN decides whether to count the current MBMS service on the MBMS carrier according to needs, so as to determine the bearing mode of the MBMS service. Specifically, if the current MBMS service needs to be counted, the UTRAN sends MBMS access information on the MBMS carrier, and the MBMS access information carries indication information that needs to be counted.

[0122] The counting process between UTRAN and UE can be completed on the MBMS carrier, or it can be completed on the MBMS carrier and the non-MBMS carrier respectively. For example, the counting instruction is provided on the non-MBMS carrier, and the counting operation is specifically completed on the MBMS carrier. .

Embodiment 3

[0124] In this embodiment, the UTRAN uses the MBMS carrier to send the indication information of the MBMS service change to the UE through the MICH channel, and correspondingly, the UE receives the service change information indicated by the network on the MBMS carrier. Then, step 1105 becomes step 1105':

[0125] Step 1105': UTRAN uses the MBMS carrier to send the indication information of the MBMS service to the UE through the MICH channel, and uses the non-MBMS carrier to send the service control information of the MBMS service to the UE through the MCCH channel.

[0126] Correspondingly, step 1203 becomes step 1203':

[0127] Step 1203': UE monitors MICH channel and / or MCCH channel, and obtains service change indication information on MBMS carrier.

Abstract

The invention discloses a method for sending multimedia broadcast / multicast service (MBMS), which includes: a1. Network informs UE about the single-distributed carrier information of MBMS. a2. Network determines the carrier style of the current MBMS when it receives the instruction for starting the conversation. a3. Network sends controlling information and instruction to UE, and establishes the carriers according to the determined style, then transmits the current MBMS service to UE via carrier of MBMS.

Description

technical field [0001] The invention relates to multimedia broadcast / multicast service (MBMS) technology, in particular to a method for sending and receiving an MBMS service based on a single carrier. Background technique [0002] Multicasting and broadcasting are techniques for delivering data from one source to multiple destinations. In a traditional mobile communication network, a cell multicast service or a cell broadcast service (CBS, Cell Broadcast Service) allows low bit rate data to be sent to all users through a cell shared broadcast channel, and this service belongs to a message service. [0003] Now, people's demand for mobile communication is no longer satisfied with telephone and message services. With the rapid development of the Internet (Internet), a large number of mobile multimedia services have emerged. Some of these mobile multimedia services require multiple users to receive the same data at the same time, such as video on demand, TV broadcasting, video...
