Embodiment Construction

[0018] Below according to accompanying drawing and embodiment the present invention will be described in further detail:

[0019] The present invention solves the DTMF / FSK compatible problem by combining the two systems when sending out the caller ID, and the hardware circuit of the wireless access box needs to support the generation of DTMF and FSK signals at the same time. The method is that the wireless base station transmits the incoming call number to the wireless access box. After receiving the incoming call number from the network, the wireless access box first sends DTMF and then FSK, that is, performs DTMF / FSK fusion according to the incoming call number, and finally passes The user interface circuit (such as RJ11) generates a caller ID signal, which is sent to an external phone to generate a caller ID. The present invention is unique, novel, simple and easy in terms of the fully automatic compatible external telephone caller display method.

Abstract

Through user interface circuit, wireless access box is connected to telephone. The method includes following steps: (1) wireless access box receives number of incoming call from network; (2) after receiving number of incoming call, wireless access box sends out DTMF display data of incoming call according to DTMF protocol first, then sends out first ringing sound; after first ringing sound, sends out FSK display data of incoming call according to FSK protocol and subsequent ringing. The invention solves issue that incoming call display cannot be recognized caused by different telephone systems. Using full automatic recognition mode, the invention realizes compatible of DTMF / FSK systems. Wireless access box is not restricted by external phone sets.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to a DTMF / FSK compatible method for a wireless access box to realize caller display Background technique [0002] The wireless access box is a wireless access terminal, which is connected to the telephone through the user interface circuit (such as RJ-11 interface), and can adopt wireless access methods such as GSM, CDMA, WCDMA, etc. Receive and make local, domestic and international calls. The wireless access box itself usually does not have an operation interface (including display and keyboard), and all operations on it are completed through the telephone set connected to it. From the user's point of view, this operation is almost the same as that of PSTN. The access box is equivalent to a small switch function, so the wireless access box is an effective supplement to PSTN, especially in sparsely populated countries and cities, it has broad application prospects f...
