The embodiment part of the present invention takes the Bluetooth GSM dual-mode phone as an example. The "Bluetooth GSM dual-mode phone" in the embodiment can not only access the GSM switching network through the GSM wireless network, but also has the ability to connect to the AP device (AP) through the Bluetooth protocol interface. Able to access to PSTN network) function.

Below in conjunction with accompanying drawing, the implementation of technical scheme is described in further detail:

In order to illustrate the function of the AP in the present invention and the business process in the present invention, dual-mode telephone is explained: in the following description and accompanying drawing, AP is also called HOMEBOX, cordless telephone landline, landline, in PHS network It is especially called the PHS cordless telephone landline, and the dual-mode telephone is also called the sub-machine and sub-machine of the AP.

A local telephone number uniquely represents an AP, which is a device used to provide dual-mode telephone access. Features of AP devices include:

(a) It can establish a connection with the dual-mode phone through the Bluetooth protocol or WLAN, PHS and other protocols, and the AP and the dual-mode phone can exchange signals in the communication link through this connection to realize functions such as short message transmission.

(b) After the dual-mode phone is successfully registered on the AP, the AP assigns a serial number to the dual-mode phone, and the number is stored in the AP and also in the SCP.

(c) The AP has the short message function, and can send and receive short messages through the short message center it belongs to, and send and receive short messages through FSK or DTMF signals.

Fig. 1 is a system network diagram of the dual-mode phone of the present invention sending and receiving short messages, pointing out the equipment and connection of the present invention. The system of the present invention includes: intelligent network service control point equipment SCP, dual-mode telephone, dual-mode telephone home network short message center SC, dual-mode telephone access point device AP, dual-mode telephone access point equipment home network short message center APSC, Short message gateway SMGW and public telephone network, etc.

Connections are established between the SCP and the SC, and between the SCP and the APSC for exchanging authentication messages. Connections are established between the SMGW and the SC, and between the SMGW and the APSC for forwarding short messages. The connection between AP and APSC is a PSTN voice channel, which is used for AP to send short messages to APSC through FSK or DTMF signals, and for APSC to send short messages to AP through FSK or DTMF signals. The AP and the dual-mode phone are connected through protocols such as the Bluetooth protocol, the WLAN protocol, or the PHS protocol, and this connection can transmit short message content. Dual-mode phones and ordinary phones can still send and receive short messages through the home network—as long as the signal between the phone and the home network is normal.

In the present invention, an intelligent network service module is loaded on the SCP of the service control point device, and the service module receives the authentication request from the outside and provides the authentication result to the outside; Registration data, etc.

In the present invention, when APSC sends a short message to an AP type terminal, it first goes to the service control point device for authentication, and forwards the short message according to the authentication result so that the short message reaches the real called terminal and generates a correct bill. Before sending the short message to the dual-mode phone, the SC first goes to the service control point device for authentication, and forwards the short message to the AP according to the authentication result, and finally the AP sends it to the dual-mode phone.

In this embodiment, the wireless side network in FIG. 1 is a GSM network, the dual-mode phone is a bluetooth GSM network mobile phone, and the connection between the short message center SC and the SCP of its home network is based on TCP/IP. In this embodiment, an authentication message and an authentication message response of "checking dual-mode phone registration" are added between the SC and the SCP. The AP is also a telephone set in the fixed telephone network PSTN, and the data transmission between the AP and its home network short message center APSC is based on DTMF or FSK signals. The connection between the APSC and the SCP is based on TCP/IP. In this embodiment, an authentication message and an authentication message response of "checking dual-mode phone registration" are added between the APSC and the SCP. The protocol between SC and SMGW, and between APSC and SMGW is "Short Message Gateway Protocol". This protocol supports short message content forwarding between SC and APSC and short Message routing setup and analysis.

The SMGW forwards the short message to the short message center to which the called terminal belongs;

The short message center to which the called terminal belongs sends a short message to the called terminal, and the called terminal displays the content of the short message.

As shown in Figure 5, the following describes the processing flow of the dual-mode phone receiving short messages:

The calling terminal sends a short message, and the short message is sent to the short message center of the called terminal through the short message center to which the calling terminal belongs, that is, the short message center to which the dual-mode phone belongs;

The short message center belonging to the dual-mode phone initiates an inquiry to the SCP to inquire about the destination terminal number;

The SCP returns the new destination terminal number to the SC;

The SC uses the new destination terminal number provided by the SCP to send a short message to the SMGW;
