Description
Technical field
The present invention relates to field of mobile communication, relate in particular to the data service that GSM 1X mobile subscriber uses cdma network.
Background technology
In order to solve GSM user's data business demand, operator has proposed the solution of GSM 1X, 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 function), in the technical specification of QualCom and CHINAUNICOM, be called GGG (GSM 1X GlobalGateway, GSM 1X universal gateway).Can be referred to as FLR (Foreignsubscriber Location Register, external user location register) from view of function.This functional entity is undertaken alternately by the different entities in signaling link and two networks, and is easy for what narrate, the unified FLR that is called among the present invention.FLR is a kind of prior art, and detail 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 " GSM 1X technical scheme " is: when the user when called, regulation FLR should net HLR (Home Location Register to GSM, attaching position register) the indication user is busy in the message of returning (Provide_Roaming_Number_Ack), 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 is to VLR (Visited Location Register, VLR Visitor Location Register) do not carry rear subscriber number in the Provide_Roaming_Number_Req of Fa Songing (the obtaining the roaming number request) message, 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 Provide_Roaming_Number_Ack (the obtaining the roaming number response) 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.
