20130303235 | METHOD FOR REDUCING FREQUENCY BAND INTERFERENCE FOR MULTI-MODE TERMINAL, MULTI-MODE TERMINAL, AND NETWORK DEVICE - A method for reducing frequency band interference for a multi-mode terminal, including: using a first frequency band to establish a first service in a first network standard; using a second frequency band to establish a second service in a second network standard; when determining that the first frequency band and the second frequency band interfere with each other, updating a frequency band capability support state or reporting an interference collision event to a network corresponding to a low-priority service, so that the network corresponding to the low-priority service updates a frequency band used by the low-priority service to a frequency band that has less interference with a frequency band used by a high-priority service, and establishing the low-priority service according to the updated frequency band. According to the embodiments of the present invention, interference between frequency bands of the multi-mode terminal may be reduced. | 11-14-2013 |
