Embodiment 1

[0047] The present invention also provides a multimedia broadcast / multicast service data transmission method, such as Figure 7 Shown, be embodiment 1 of the present invention, specifically comprise the following steps:

[0048] Obtain the UE type information fed back;

[0049] Count the number of UEs that match the types of existing media resources to be transmitted, and determine whether the number of UEs is greater than a predetermined threshold, and if it is greater than the predetermined threshold, then use the PtM bearer method to send the existing media resources to be transmitted If the media resource is not greater than the predetermined threshold, the existing media resource to be transmitted is sent in a PtP bearer manner.

[0050] Before obtaining the feedback user terminal type information, a step of sending query UE type information may also be included, which may be sending query UE type information to MBMS service UEs that have been initially counted.

Abstract

The invention relates to a system, a method and a terminal for transmitting multimedia broadcasting / multicasting service data. The system comprises: a wireless network controller, a service general packet radio service supporting node, a gateway general packet radio service supporting node, a broadcasting / multicasting service center, a user terminal type inquiry module, a database and a processing module; the method includes the following steps: obtaining the feedback user terminal type information; counting the amount of user terminals matched with the type of the existing media resource to be transmitted, and judging whether the amount of user terminals is more than the predetermined threshold value; if so, a point-to-multipoint load mode is adopted to send the exiting media resource to be transmitted; if not, a point-to-point load mode is adopted to send the existing media resource to be transmitted; the terminal comprises a mobile communication terminal and a user terminal type feedback module. The waste of network resource can be avoided by the invention, thereby guaranteeing the validity of resource transmission.

Description

technical field [0001] The invention relates to a multimedia broadcast / multicast service data transmission system, method and terminal, belonging to the field of network communication. Background technique [0002] With the improvement of people's living standards and the development of communication technology, users not only need traditional mobile communication services such as telephone and messaging, but also have further requirements for mobile multimedia services. Since the existing IP multicast technology is not suitable for mobile communication networks to carry out mobile multimedia services, the 3rd Generation Partnership Project (3GPP) proposed Multimedia Broadcast / Multicast Services (MultimediaBroadcast / Multicast Services, hereinafter referred to as: MBMS) services, in A data source is provided in the mobile communication network, which is used to send data point-to-multipoint services to multiple user terminals, so as to realize network resource sharing and imp...
