Embodiment Construction

[0029] In the prior art, when a user uses a mobile terminal to use MBMS services, and the signal strength of the current cell is lower than the signal quality of other adjacent serving cells, the network side will instruct the mobile terminal to switch to a serving cell with better signal quality, and switch to The serving cell of the cell may not provide MBMS service.

[0030] In order to solve the above-mentioned problems existing in the prior art, the technical solution adopted in the embodiment of the present invention arranges the cell providing MBMS service in the front row of the measurement sequence and generates a corresponding measurement report, so that the network side can instruct the mobile station according to the measurement report. The terminal camps or switches to the cell that provides the MBMS service, which can improve the quality of the MBMS service and user experience.

[0031] In order to make the above objects, features and advantages of the present in...

Abstract

A mobile terminal and a method for switching a serving cell thereof, the method comprising: measuring the signal quality of a current cell and an adjacent cell; sorting the current cell and the adjacent cell in descending order of signal strength to obtain a first cell measurement sequence; When it is detected that the mobile terminal is using the MBMS service, and the cell providing the MBMS service is not the cell with the first rank in the first cell measurement sequence, set the signal strength value in the first cell measurement sequence to be greater than the threshold And the cells that provide the MBMS service are rearranged in the order of decreasing signal strength to obtain a second cell measurement sequence before the cell in the first order; generate a measurement report according to the second cell measurement sequence and send it to the network side ; receiving cell switching instruction information generated by the network side according to the measurement report, and switching to a corresponding serving cell according to the cell switching instruction information. The above solution can improve the quality of the MBMS service.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a mobile terminal and a method for switching a serving cell thereof. Background technique [0002] Mobile terminals refer to computer devices that can be used on the move, broadly speaking, they include mobile phones, notebooks, tablet computers, POS machines, and vehicle-mounted computers. With the rapid development of integrated circuit technology, the processing capability of mobile terminals has already possessed powerful processing capabilities, and mobile terminals are changing from a simple communication tool to a comprehensive information processing platform, which also adds a broader development space to mobile terminals . [0003] Multimedia Broadcast Multicast Service (MBMS) is a multimedia broadcast multicast function defined in 3GPPR6, and is the cornerstone for mobile terminals to develop television services. MBMS supports two modes of multimedia broadcasti...
