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 invention provides a method and a system for avoiding the radio-frequency interference of a terminal. The terminal supports a first mode and a second mode, and further, a first frequency range in the first mode and a second frequency range in the second mode are mutual interference frequency ranges. The method comprises the following steps of: inquiring whether a second service which is carried out works in the second frequency range or not when the terminal initiates a first service and if the first service is initiated in the first frequency range; and if the second service works in the second frequency range, setting the first frequency range in a disabled state, and sending the information of the first frequency range set in the disabled state to a network side. By using the method and the system for avoiding the radio-frequency interference of the terminal, any modification is not necessary to carry out on the network side; the signaling between a network and the terminal is also not necessary to additionally add; the radio-frequency interference can be avoided by only utilizing a relevant message in a conventional network necessarily; and the resources of the frequency ranges can be saved, so as to improve the utilization rate of the resources of the frequency ranges.

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 ...
