Embodiment Construction

[0037] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0038] The present invention solves the problem of radio frequency interference by dynamically changing the capability information of the terminal when initiating a service. When a dual-mode dual-standby terminal conducts business in a certain mode, it will record the current working frequency band information; then when initiating business in another mode, it will query the working frequency band of the mode that already has business in progress, if there is interference in the frequency band If possible, the terminal will prohibit the frequency band that is about to initiat...

Abstract

The present invention provides a method and system for avoiding terminal radio frequency interference. The terminal supports a first mode and a second mode; a first frequency band in the first mode and a second frequency band in the second mode interfere with each other. The method comprises: when the terminal initiates a first service, if the first service is initiated at the first frequency band, querying whether an ongoing second service works in the second frequency band; if the second service works in the second frequency band, setting the first frequency band to a disabled state, and sending to a network side information of the first frequency band set to the disabled state. The above method and system for avoiding terminal radio frequency interference do not require any change on the network side or addition of signaling between the network and the terminal. The radio frequency interference can be avoided by just using related messages in the existing network, and frequency band resources can be saved, thereby improving the utilization rate of the high-frequency band resources.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method and system for avoiding terminal radio frequency interference. Background technique [0002] There are many modes in the current mobile communication system, including those represented by Global System for Mobile Communications (GSM) / General Packet Radio Service (GPRS) / Enhanced Data Rates for GSM Evolution (EDGE) / Code Division Multiple Access (CDMA) The second generation mobile communication system (2G) technology and the third generation mobile communication system (3G) technology represented by Time Division Synchronous Code Division Multiple Access (TD-SCDMA) / Wideband Code Division Multiple Access (WCDMA). In comparison, the third-generation mobile communication system technology has the advantages of advanced technology, strong data service capabilities, and large user capacity, but the disadvantages are also obvious incomplete coverage and relatively high ...
