A gateway and method for SMS intercommunication between the CDMA and GSM

Abstract

The disclosed method to interact SMS between CDMA and GSM comprises: a. the first network user sends SMS to a user in a second network; b. the first network SMS center converses the stop-calling message signaling of SMS into the route request message recognized by the second network to send to the attribution position register in the second network for route; c. recognizing the returned route response message from said register, and sending the stop-calling message to the second network when the response is success; and d. auto-recognizing the stop-calling message to converse into the response message for the first network to let the latter print dialogue menu. This invention reduces hardware cost greatly, and improves the communication stability and charge accuracy.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a gateway and a method for realizing intercommunication of CDMA and GSM short messages. Background technique [0002] At present, the short message service volume is increasing day by day, and the short message service volume between the CDMA network and the GSM network has also increased to a large extent. Each operator pays more and more attention to the short message service between the CDMA network and the GSM network, and hopes to use The lowest cost ensures that the short message service between the CDMA network and the GSM network is safer and more stable, and the billing is also more accurate. [0003] There are two methods for realizing CDMA and GSM short message intercommunication in the existing technology: [0004] The first kind: as patent CN200610046411 discloses a kind of method that realizes CDMA and GSM short message intercommunication, utilizes S...

AI Technical Summary

Problems solved by technology

Not very flexible in practice

[0007] 2. The security and stability of the message is relatively poor. The SMPP protocol is for the intercommunication of CDMA and GSM short messages in the public network.

Messages are more likely to be lost

And there are security risks

[0008] 3. The billing for user messages is inaccurate, because the intercommunication of CDMA and GSM short messages realized by using the SMPP protocol, for messages sent from the CDMA network to the GSM network, or from the GSM network to the CDMA network, the short message that initiates the call The message center cannot accurately know whether the message is correctly received by the target user

[0012] b. For the CDMA short message center and the GSM short message center, the billing is more complicated. It is necessary to fetch the corresponding bills from the transfer equipment and check them to complete the billing

This billing process is complex and error-prone

[0013] c. Since the intercommunication of short messages needs to be completed through the relay equipment, after passing through the intermediate environment, the stability and security of the entire system will not be very high
