Embodiment Construction

[0044] The core idea of ​​the present invention is to improve the receiving effect of TD-SCDMA dual-receiver terminals on multimedia broadcast and multicast services by introducing dual receivers with power-saving mode within the protocol framework of TD-SCDMA terminals, and can also reduce TD-SCDMA Device power consumption for a dual receiver terminal. Such as figure 1 As shown, the power-saving mode means that the dual-receiver terminal only turns on the main receiver and the auxiliary receiver is turned off, which can reduce the power consumption of the device at this time; the non-power-saving mode means that the dual-receiver terminal turns on the main The receiver can improve the receiving gain of the terminal at this time. In the power-saving mode, the TD-SCDMA dual-receiver terminal receives MBMS signals in the cell through the main receiver; while in the non-power-saving mode, the TD-SCDMA dual-receiver terminal Receive the MBMS signal of the cell where it resides. ...

Abstract

The invention discloses a method and device for realizing a multimedia broadcast multicast service (MBMS). The method comprises the following steps of: (1) receiving the MBMS and judging whether the ordered MBMS is released in a resident cell or not; (2) judging whether the ordered MBMS is a broadcast service or not; (3) receiving a multipath signal of the MBMS, performing a step (4) if a main receiver is switched on and an auxiliary receiver switched off, and performing a step (5) if both the main receiver and the auxiliary receiver are switched on; (4) if primary common control physical channel received signal code power (PCCPCH RSCP) is lower than a first threshold value, switching the auxiliary receiver on and performing the step (3), otherwise, directly the performing step (3); and (5) if the PCCPCH RSCP is higher than a second threshold value, switching the auxiliary receiver off and performing the step (3), and if the PCCPCH RSCP is lower than the second threshold value and notlower than a third threshold value, directly performing the step (3). In the method, the switch-on or switch-off of the auxiliary receiver of a double-receiver terminal is controlled according to thevalue of the PCCPCH RSCP, so that terminal receiving gain is increased, and the consumption of terminal equipment is lowered.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method and device for realizing multimedia broadcast and multicast services. Background technique [0002] With the popularization and application of 3G technology, mobile communication users no longer simply use mobile terminals (mobile phones) as basic communication tools. Mobile terminals have been endowed with more and more multimedia functions. Time Division Synchronization Code Division Multiple Access (TD-SCDMA) technology has developed Multimedia Broadcast Multicast Service (MBMS) within the framework of TD-SCDMA technology. Mobile multimedia services provide a very good platform. MBMS business can be used to transmit low-speed text, and can also be used to transmit high-speed multimedia services. The MBMS service has two modes: broadcast and multicast. The MBMS service of time division synchronous code division multiple access is divided into two phases ...
