Method and system for acquiring frequency point where mobile terminal resides

Abstract

The invention discloses a method and system for acquiring a resident frequency point of a mobile terminal. The method comprises the steps that the mobile terminal determines channel serial numbers corresponding to frequency points capable of being used by the mobile terminal according to network side configuration; the mobile terminal determines channel serial numbers corresponding to frequency points capable of being allowed by the mobile terminal according to the frequency capacity of the mobile terminal; a network side determines channel serial numbers corresponding to frequency points capable of being allowed by the mobile terminal according to the frequency capacity reported by the mobile terminal and determines channel serial numbers corresponding to frequency points capable of being used by the mobile terminal according to the configuration of the network side; the network side and the mobile terminal respectively determine a sequence number corresponding to a channel serial number corresponding to a frequency point where the mobile terminal finally resides through a Hash algorithm according to the channel serial numbers corresponding to the frequency points capable of being used by the mobile terminal and the channel serial numbers corresponding to the frequency points capable of being allowed by the mobile terminal, wherein the channel serial numbers corresponding to the frequency points capable of being used by the mobile terminal and the channel serial numbers corresponding to the frequency points capable of being allowed by the mobile terminal are respectively calculated by the network side and the mobile terminal. Due to the fact that the uniqueness of a channel serial number corresponding to a newly-increased expansion frequency point in a frequency band level is guaranteed, the regular work of a roaming service can be effectively guaranteed.

Description

technical field [0001] The present invention relates to the field of communication, in particular, to a method and system for acquiring a frequency point where a mobile terminal resides. Background technique [0002] Frequency is the most important and precious resource of mobile communication. With the continuous improvement of CDMA network and the rapid growth of CDMA smart users, more frequency resources are urgently needed to support the expansion and development of CDMA network. The frequency resource must also be within the range of the frequency band that the mobile terminal can support. [0003] Assuming that a CDMA network has already used the Subclass (X) (ie, sub-level (X)) frequency band of BandClass (A) (ie, frequency band level (A)), according to the demand for frequency resources, it is necessary to add some frequency bands for network expansion , these newly available frequency resources may neither be within the Subclass(X) of the BandClass(A) nor completel...

Problems solved by technology

[0004] If the EV-DO or CDMA system is deployed on the newly increased available frequency and the existing 3GPP2 frequency band definition method is adopted, DOB terminals may appear (in order to use 1~3 DOA (support one carrier, downlink rate: 3.1M , Uplink rate: 1.8M) Carrier terminals can bundle carriers, downlink rate: number of carriers × 3.1M, uplink rate: number of carriers × 1.8MHz) Carrier bundling and roaming paging cannot be performed across frequency bands
