Problems solved by technology
The existing technology is to reduce interference by using filters in the transmission and reception directions of the radio frequency, but even so, the uplink transmission on the PS side will cause strong co-channel interference to the downlink reception on the CS side

Embodiment Construction
[0053] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0054] Aiming at the problem that co-channel interference occurs when existing wireless communication terminals process services of two communication systems, the present invention provides a service processing method, device and wireless communication terminal applied to wireless communication. The wireless communication terminal can simultaneously process the first type of service based on the first communication standard, and process the second type of service based on the second communication standard. Among them, such as figure 1 As shown, the business processing method includes:
[0055] Step 11, when the second type of service needs to be processed, judge whether the wireless communication terminal is currently processing the first type of servic...

A method, system and wireless communication terminal for service processing are provided in the embodiments of the present invention. The embodiments are applied to a wireless communication terminal. The wireless communication terminal can process a first type of service on the basis of a first communication mode simultaneously. The method includes: before processing a second type of service in a selected frequency band, judging whether the wireless communication terminal is processing the first type of service, and generating a judging result; if the judging result indicates that the wireless communication terminal is processing the first type of service, acquiring the resident frequency band of the wireless communication terminal under the first communication mode; and selecting. from the frequency bands of a second communication mode searched by the wireless communication terminal, only the frequency band which does not overlap the resident frequency band to be used for processing the second type of service.
Description
technical field [0001] The invention relates to the communication field, in particular to a service processing method, device and wireless communication terminal. Background technique [0002] A single-card dual-standby terminal means that a UE can camp in two modes at the same time, a typical example: the CS side camps on 2G, and the PS side camps on LTE / 3G. [0003] A single-card dual-standby terminal can simultaneously perform PS services in the LTE system (supplemented by TD-SCDMA) and CS services in the 2G system through two communication subsystems. Since the two communication subsystems (LTE / 3G system and 2G system) of the single-card dual-standby multi-mode terminal are both in the working state when the CS service and the PS service are concurrent, the radio frequencies of the two communication subsystems will send and receive wireless signals at the same time. Therefore, there is mutual interference, that is, a transmitter in one mode will affect the sensitivity o...
