Problems solved by technology

The existing way of using non-MBMS carrier frequency to send MBMS services makes MBMS occupy a large amount of existing wireless resources, so that on the one hand, it greatly affects the transmission of other existing services; on the other hand, it also greatly limits The types of services that MBMS can provide at the same time

Embodiment 1

[0077] Embodiment 1, the access network dynamically selects the carrier frequency mode according to the service attribute of the MBMS service.

[0078] The core network sends an instruction to start the MBMS service to the access network. According to the service attribute of the MBMS service carried in the instruction, if the duration of the service is very short, the access network selects the current MBMS service according to the preset selection strategy. The MBMS service is sent on the non-MBMS carrier frequency; otherwise, the MBMS service is sent on the MBMS carrier frequency.

[0079] If the MBMS service is selected to be sent on a non-MBMS carrier frequency, the non-MBMS carrier frequency can further be selected to be sent. The implementation method belongs to the prior art and will not be described in detail here.

Embodiment 2

[0080] In the second embodiment, the core network dynamically selects the carrier frequency mode according to the service attribute of the MBMS service.

[0081] According to the service type of the MBMS service and the amount of data transmitted by the service, if the MBMS service lasts for a long time but the amount of data transmitted each time is small, the core network will select the current non-MBMS carrier according to the preset selection strategy. Otherwise, send the MBMS service on the MBMS carrier frequency; the core network will carry the carrier frequency information of the MBMS service in the MBMS service start instruction and send it to the access network, and the access network will send the MBMS service to the access network through the received The carrier frequency corresponding to the carrier frequency information transmits the current MBMS service.

[0082] In addition, after receiving the carrier frequency information from the core network, the access ne...

Embodiment 3

[0083] Embodiment 3, the access network dynamically selects a carrier frequency mode according to its own current resource situation.

[0084] The access network receives the instruction to start the MBMS service from the core network, and according to the use of its own current frequency resources, if there is no MBMS carrier frequency resource, it chooses to send the current MBMS service on the current non-MBMS carrier frequency; otherwise, Send the current MBMS service on the MBMS carrier frequency.

[0085] The method of this embodiment may also be a method further included after the core network or the access network selects the carrier frequency mode according to the service attribute of the current MBMS service.

Abstract

The invention discloses a method of sending the multimedia broadcast or multicast service (MBMS) operation, comprising: an MBMS carrier frequency used for distributing and bearing the MBMS operation; that the network side based on the operation attribute of the MBMS operation chooses to send the MBMS operation on the MBMS carrier frequency or non-MBMS carrier frequency according to the choosing strategy that is set beforehand. The invention at the same time also discloses a device used for sending the MBMS operation. The technic proposal provided by the invention, sufficiently utilizes the existing wireless resources, increases the using efficiency of the system resources, decreases the switching frequency of UE between the MBMS carrier frequency and the non-MBMS carrier frequency because of using the individual MBMS carrier frequency to send the MBMS operation, and at the same time satisfies the demand of the system of providing a plurality of MBMS operations.

Description

technical field [0001] The invention relates to multimedia broadcast / multicast service (MBMS) technology, especially a method and device for sending multimedia broadcast / multicast service. 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 conferencin...
