Description

The method (two) of incoming call prompting business is provided for GSM1X user

Technical field

The present invention relates to field of mobile communication, relate in particular to the data service that the GSM1X mobile subscriber uses cdma network.

Background technology

In order to solve GSM user's data business demand, operator has proposed the solution of GSM1X, promptly utilizes the data network of CDMA 1X to provide data service for GSM user.An equipment be need between cdma network and GSM network, increase for this reason and two network signals, parameter and professional conversion are responsible for.This equipment is at 3GPP2 (Third Generation Partnership Project 2,3-G (Generation Three mobile communication system) project team 2) is called IIF (Interworking and Interoperation Function in the standard, interconnected interoperability), QualCom company and CHINAUNICOM become GGG (GSM 1XGlobal Gateway, GSM 1X universal gateway) in the technical specification of oneself.And can be referred to as FLR (Foreignsubscriber Location Register, external user location register) from functional perspective.This functional entity is undertaken by the different entities in signaling link and two networks alternately.In order to simplify description of the invention, here we to unitedly call this equipment be FLR.The detail of FLR can be with reference to the N.S0028 agreement of 3GPP2.

Because CDMA 1X network only provides data service for GSM 1X user, and voice service is still provided by original GSM network, therefore as GSM 1X user during at CDMA 1X network, all incoming traffics all can not receive normally, Carrier Requirements can be notified the user by the mode of short message---incoming call prompting, in order to avoid the user omits important phone.

CHINAUNICOM's description to the incoming call prompting business in " GSM1X technical scheme " is: when the user when called, regulation FLR should the indication user hurry in the message Provide_Roaming_Number_Ack that returns to GSM net HLR (obtaining the roaming number response), and FLR should send a short message prompt by certain number call to this user simultaneously.At such business description, some main equipments in the GSM network all need to do bigger change.This be because:

1, in the GSM MAP, HLR does not carry rear subscriber number in Provide_Roaming_Number_Req (the obtaining the roaming number request) message that VLR sends, therefore FLR equipment does not know whom the calling subscriber is, thereby can't descend short-message sending to come advise called subscriber.

2, in the GSM MAP, the state that VLR does not have parameter to indicate the called subscriber in the Provide_Roaming_Number_Ack message that HLR returns hurries, so HLR can't be known called subscriber's busy condition.

In order to solve the requirement of operator to the incoming call prompting business, the solution below we have proposed.

Summary of the invention

Technical problem to be solved by this invention is to send incoming call prompting to the GSM1X user who uses the CDMA1X data service.

Technical scheme of the present invention is:

A kind of method that provides the incoming call prompting business for GSM1X user comprises:

Exhale the routing iinformation of MSC 1.1 rise to user's HLR inquiry user;

1.2 user's HLR sends the roaming number request of obtaining to FLR;

1.3 FLR returns to HLR with the access code of coming telephone number displaying center, HLR has returned to and has exhaled MSC (Mobile Switching Center, mobile switching centre);

1.4 work the MSC that exhales calling is sent to coming telephone number displaying center;

1.5 coming telephone number displaying center is according to access code or by obtaining called subscriber's number alternately with FLR, structure incoming call prompting short message;

1.6 coming telephone number displaying center is issued user's ownership short message service center with short message, short message service center sends to the user through FLR with short message; Or

1.7 coming telephone number displaying center is directly issued the user through FLR with short message.

In such scheme:

Described FLR returns to the access code of the coming telephone number displaying center of HLR, is special service number+Subscriber Number, or the roaming number of coming telephone number displaying center management.

Through FLR short message is sent to the user in the described step 1.6 or 1.7, comprising:

3.1 FLR becomes the CDMA short message format with the GSM short message conversion, sends to the MSC that the user inserts;

3.2 the MSC that the user inserts issues the user with short message;

3.3 the MSC that the user inserts returns the response that sends SMS message to FLR;

3.4 FLR returns the response that sends SMS message to called subscriber's short message service center.

Coming telephone number displaying center in the described step 1.6 is issued user's ownership short message service center with short message, comprising:

4.1 the short message service center at user place is to called subscriber's HLR inquiry called subscriber's short message routing address;

4.2 user's HLR returns called subscriber's short message routing address to short message service center;

4.3 user's short message service center sends to FLR according to called subscriber's short message routing address with short message.

The solution of utilizing the present invention to propose, only need do corresponding modification to the processing procedure at FLR and call-missing prompt center, just can under the condition of the main switching equipment in not changing CDMA net and GSM net, make operator to provide the incoming call prompting business to the GSM 1X user who uses the CDMA data service.GSM 1X user can be when using CDMA 1X data service, and still can know has incoming call, and whether the user can own decision interrupt data service, to reply some important phones.
