Embodiment Construction

[0040] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.

[0041] The present invention explains how to carry the enhanced MBMS technology in a multi-frequency point cell, that is, how to realize the function of the enhanced MBMS technology in the multi-frequency point cell of the TD-SCDMA system.

[0042] The present invention implements enhanced MBMS services in multi-frequency cells on the basis of the existing multi-frequency point line standard, such as: mobile TV service (a kind of MBMS service, which is characterized in that multiple cells all send the same TV channel). Specifically as figure 2 As shown, firstly, because the TD-SCDMA system can perform time division multiplexing on one carrier, the downlink time slot carrying the MBMS service channel can be further divided into MBSFN time slot and Non-MBSFN time slot; then in UTRAN (Universal Terrestrial Radio Configure the MBSFN tim...

Abstract

The invention relates to a method for realizing the enhancement of MBMS service in a multi-carrier cell. The method comprises the steps that a downlink time slot is divided into an MBSFN time slot and a Non-MBSFN time slot in the multi-carrier cell; the same MBMS service of each cell is configured on the MBSFN time slot while the specific MBMS service of each cell is configured on the Non-MBSFN time slot; configuration information is sent to a user terminal in the entire multi-carrier cell and the user terminal receives the MBMS service according to the configuration information. By adopting the method of the invention, the same MBMS service of each cell can improve the receiving gain of the user terminal by multi-path combination.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to an enhanced multimedia broadcast and multicast service implemented in a multi-frequency point cell in a Time Division Code Synchronization Division Multiple Access (TD-SCDMA) system (MBMS, Multimedia Broadcast Multicast Service) method. Background technique [0002] With the popularization of large-screen multi-functional mobile phones, the application of mobile data services is becoming more and more extensive. The demand for mobile communications is no longer satisfied with phone calls, messaging and mobile Internet browsing services. In order to effectively use mobile network resources, 3GPP proposed Multimedia broadcast and multicast service (MBMS, MultimediaBroadcast Multicast Service), provides a point-to-multipoint service in which a data source sends data to multiple users in a mobile network, realizes network resource sharing, and improves the utilization of...
