Specifically, the utlity model has following advantage:

Under the metastable situation of cellphone subscriber's quantity, the TD-SCDMA network can strive for that by this and GSM network sharing mode part GSM user forwards the TD-SCDMA network to, to satisfy basic operation needs.GSM user is when TD-SCDMA user moves, and owing to multiple reason generally is not eager to abandon its GSM number, but more hope can be answered GSM and TD-SCDMA number simultaneously, can select GSM or TD-SCDMA to make a call as caller as required simultaneously.

The TD-SCDMA network has to be equivalent to mend net for the TD-SCDMA network by this sharing mode in the face of the comprehensive inadequately problem of the network coverage at first stage of construction, can make full use of the comprehensive advantage of the GSM network coverage.

Use the user of TD-SCDMA and GSM network can on a mobile phone, realize TD-SCDMA and gsm communication function simultaneously, and do not need to carry the mobile phone of two single systems, user-friendly, carry.

TD-SCDMA module in the utility model and gsm module are shared cell phone apparatus, and the overall system cost is low.
