Embodiment Construction

[0040] The dual-mode / multi-mode mobile terminal call transfer method and device of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] Referring to FIG. 1, FIG. 1 is a schematic diagram of the interaction relationship between the terminal, the GMSC and the HLR in the process of implementing the call transfer function. The processing process of the system is as follows: first, the terminal establishes a connection with the GMSC, and then the GMSC goes to the HLR to request the user's information. If the required information is not obtained, it goes to the HLR data storage area of ​​the mode 2 number to query the call transfer information to realize the call transfer. A more detailed description is given below in conjunction with specific embodiments.

[0042] With reference to Fig. 2, illustrate according to the dual-mode / multi-mode terminal call transfer method of the present invention; The method comprises the followin...

Abstract

The method comprises: 202) sending the user's registration message comprising the correlated number to the user's home location register in order to register a call transfer function; 204) enabling the call transfer function of the correlated number, and setting the correlated number as the user's number at current mode; 206) if finding the user is busy during calling, then enquiring the call transfer information of the called number to make a calling; if not capable of realizing the calling, then enquiring the call transfer information of its correlated number to make the calling. The invention also provides a call transfer device used in dual-mode / multi-mode terminal.

Description

technical field [0001] The invention relates to a method and device for call transfer in the field of mobile communication, in particular to a method and device for call transfer of a dual-mode or multi-mode mobile terminal. Background technique [0002] With the development of third-generation mobile communication technology, third-generation mobile technologies such as TD-SCDMA (Time Division Synchronous Code Division Multiple Access), CDMA (Code Division Multiple Access), and WCDMA (Wideband Code Division Multiple Access) have gradually entered the practical stage. . However, due to the unavoidable network coverage and other problems at the beginning of the construction of the third-generation mobile technology network, there is a need to support the second-generation mobile communication technology on the third-generation communication terminal. At the same time, with the development of technologies such as wireless local area networks, it is urgently required for termi...
