Embodiment 1
[0036] The following takes a dual-card dual-mode mobile phone as an example to describe in detail. In this embodiment, the first network is a GSM network, and the second network is a TD-SCDMA network.
[0037] The terminal card 1 of the dual-card dual-mode mobile phone currently resides in cell 1 (GSM network cell), and the terminal card 2 currently resides in cell 2 (GSM network cell). When terminal card 1 complies with the protocol (3GPP TS 45.008 protocol) When the cell reselection condition of the different system is met, the terminal card 1 and the terminal card 2 are triggered to perform the reselection of the adjacent cell of the different system (TD-SCDMA network adjacent cell), wherein the terminal card 1 is set as the master card.
[0038] First, measure the signal strength of the TD-SCDMA network adjacent cell of cell 1 and the TD-SCDMA network adjacent cell of cell 2 (corresponding figure 1 Step S1).
[0039] Specifically, please refer to figure 2 , execute step...
Embodiment 2
[0055] In this embodiment, the first network is a TD-SCDMA network, and the second network is a GSM network.
[0056] The terminal card 1 of the dual-card dual-mode mobile phone currently resides in cell A (TD-SCDMA network cell), and the terminal card 2 currently resides in cell C (TD-SCDMA network cell). When the terminal card 2 conforms to the protocol (3GPP TS25. 304) When the specified conditions for cell reselection of different systems are triggered, terminal card 2 and terminal card 1 are triggered to perform reselection of neighboring cells of different systems (GSM network neighboring cells), wherein terminal card 2 is set as the main card.
[0057] First, measure the signal strength of the GSM network neighbors of cell A and the GSM network neighbors of cell C (corresponding figure 1 Step S1).
[0058] Specifically, please refer to image 3 , execute step S31, obtain the GSM network neighbor list of the TD-SCDMA network cell where each terminal card resides, that ...
Embodiment 3
[0082] Terminal card 1 of the four-card dual-mode mobile phone currently resides in cell 1 (GSM network cell), terminal card 2 currently resides in cell 2 (GSM network cell), and terminal card 3 currently resides in cell A (TD-SCDMA network cell). cell), the terminal card 4 currently resides in cell C (TD-SCDMA network cell).
[0083] When terminal card 1 meets the conditions for different-system cell reselection stipulated in the protocol, terminal card 1 and terminal card 2 are triggered to perform reselection of different-system adjacent cells (TD-SCDMA network adjacent cells), while terminal card 3 continues to reside in cell A , the terminal card 4 continues to reside in cell C.
[0084] Among them, the process of terminal card 1 and terminal card 2 performing TD-SCDMA network neighbor reselection can refer to figure 2 , terminal card 1 is the main card.
