It is definite that the terminal can support that which carrier frequency communicates when dispatching from the factory; Communication protocol version according to terminal communication is supported is different; Then the carrier frequency of terminal support is different, generally supports the communication protocol of more recent version communication protocol compatibility than legacy version, therefore supports also to support usually than the employed carrier frequency of legacy version communication protocol than the terminal of new traffic agreement; Therefore OMC can confirm the probability size that each carrier frequency is used by the terminal according to the operating position of each carrier frequency at the different communication protocol version.
Step S102, BTS be according to said basic carrier frequency tabulation and expansion carrier frequency list configuration Overhead Message, the information that makes the Overhead Message after the configuration carry the carrier frequency in basic carrier frequency tabulation and the tabulation of expansion carrier frequency;
According to current mechanism; Sector parameters in the Overhead Message can carry the carrier frequency information in the carrier frequency tabulation; Then the embodiment of the invention preferably adopts sector parameters to carry the carrier frequency in basic carrier frequency tabulation and the tabulation of expansion carrier frequency; Different is that the carrier frequency in basic carrier frequency tabulation and the tabulation of expansion carrier frequency is distinguished in sector parameters, promptly utilizes parameters different in the sector parameters to carry the information of the carrier frequency in basic carrier frequency tabulation and the tabulation of expansion carrier frequency respectively.
Step S103, the Overhead Message after BTS will dispose are broadcast to the terminal of sub-district in the BTS, so that carrier frequency and the successful access network that use when confirming access network according to said Overhead Message at the Idle state terminal.

After the AT start searches network, can monitor overhead channel.If confirm that according to Sector Parameters message the primary channel tabulation does not comprise any carrier frequency, then AT monitors current carrier frequency.Comprise carrier frequency if confirm the primary channel tabulation, then AT uses the Hash hash algorithm in the primary channel tabulation, to select a carrier frequency, and uses the carrier frequency access network of selecting.
2) for the AT that supports EIDP and QIDP
After the AT start searches network, can monitor overhead channel.If confirm that according to Sector Parameters message primary channel tabulation and extended channel list all do not comprise any carrier frequency, then AT monitors the current carrier frequency that is using; If primary channel tabulation or extended channel list comprise carrier frequency, AT at first constructs the carrier frequency S set that is used for carrying out hash algorithm:
1) S1 is the intersection of primary channel tabulation and extended channel list;
2) based on the negotiation attribute SupportedCDMAChannels of routing update Route Update agreement; Definite negotiation carrier frequency that obtains with the BTS negotiation; It is the frequency that comprises among the SupportedCDMAChannels; From S1, remove the frequency that is not included among the SupportedCDMAChannels, obtain S;
3) obtain S after, AT uses hash algorithm to select a carrier frequency, and uses the carrier frequency access network of selecting.
