Abstract
The present invention relates to a method for providing third-party positioning for a GSM mobile user who enters a CDMA network by the CDMA network. The method comprises the following steps: CDMA MPC considers a GC gateway as CDMA MSC visited by a user; a triggering positioning text message MT is transmitted to the corresponding GC gateway; the GC gateway judges that the triggering positioning text message MT is a text message MT used for positioning service, and the text message MT is transmitted to a GSM user through CDMA MSC; after the GC gateway receives a response message returned from CDMA MSC, the GC gateway returns a response message to CDMA MPC; the GSM user who roams in the CDMA network transmits a text message MO about positioning agreement to CDMA MPC through CDMA MSC. The present invention only needs to modify processing procedures of the GC gateway and CDMA MPC, and the present invention provides third-party positioning service of the CDMA network for the GSM user who roams in the CDMA network.
Description
Technical field
The present invention relates to field of mobile communication, relate in particular to the GSM mobile subscriber who enters cdma network is positioned professional technology.
Background technology
In order to realize the mutual roaming of GSM network and cdma network, need between cdma network and GSM network, increase an equipment and be responsible for two network signals, parameter and professional conversion.This equipment is at 3GPP2 (Third Generation Partnership Project 2, the standardized partnership projects 2 of 3G (Third Generation) Moblie) is called IIF (Interworking and Interoperation Function in the standard, interconnected interoperability function), in the technical specification of CHINAUNICOM, be called G﹠amp; C gateway (GSM﹠amp; The CDMA gateway), easy for what narrate, the unified G﹠amp that is called among the present invention; The C gateway.G﹠amp; The C gateway is a kind of prior art, and detail can be with reference to the N.S0028 agreement of 3GPP2.
In the cdma network, the triggering mode of positioning service comprises that mobile node triggers (positioning oneself) and network-triggered (third party location) dual mode.Easy in order to narrate, the present invention claims these two kinds of different triggering modes to be respectively to position oneself the positioning service with the third party.Positioning oneself is the positioning service that is triggered by mobile node, mainly comprises self-position inquiry, electronic chart etc.; The third party location is the positioning service by network-triggered, mainly comprise other people position enquiring, vehicle tracking etc., in the implementation procedure of this class business, network need be confirmed at present by the service area at ISSUER place by certain mechanism, thereby set up certain connection (signaling connection, TCP/IP connection etc.), and need to judge whether retrieval side has the right the people that is retrieved is carried out position enquiring.According to prior art, when GSM user roams to cdma network, can equally use with this network users of CDMA and position oneself professional, but can not use third party's positioning service.Reason is as follows:
1) third party's positioning service flow process comprises: CDMA MPC (CDMA Mobile PosittonCenter, the CDMA mobile positioning center) need send a triggered location short message MT (Mobile Station Termination to the user that is positioned, travelling carriage is exhaled eventually), the user that is positioned returns a short message MO (Mobile Station Origination who is used for positioning service to CDMA MPC, mobile originated), whether expression is agreed to be positioned.
2) GSM user comprises in cdma network sending and receiving short messages flow process: must pass through G﹠amp by the GSM short message service center of its ownership during the GSM receiving short-message of user; The C gateway is sent to the CDMAMSC (CDMA mobile switching centre) that the user visits; In like manner, when GSM user sends SMS message, also must pass through G﹠amp; The C gateway is sent to its GSM short message service center that belongs to.
Therefore according to present technology, CDMA MPC can't send the short message MT that this is used to locate to the GSM user who roams to cdma network.
Summary of the invention
Technical problem to be solved by this invention is the transmission that solves the short message MT that is used to locate, thereby provides the third party positioning service to the GSM user who roams to cdma network.
Easy for what narrate, do following agreement:
Mobile Station Termination: travelling carriage is exhaled eventually, the unified MT that is called among the present invention;
Mobile Station Origination: mobile originated, the unified MO that is called among the present invention;
CDMA Mobile Position Center:CDMA mobile positioning center, the unified CDMA MPC that is called among the present invention.
Technical scheme of the present invention is:
1.1 when CDMA MPC need be when the GSM user who roams to cdma network sends the triggered location short message MT, with G﹠amp; The C gateway is regarded the CDMA MSC that the user visits as, to corresponding G﹠amp; The C gateway sends the triggered location short message MT; CDMA MPC can obtain corresponding G﹠amp according to GSM Subscriber Number or number section; The address of C gateway;
1.2G﹠amp; It is a short message MT that is used for positioning service that the C gateway is judged this, and the CDMA MSC that then sends it to GSM user and visited is sent to GSM user by CDMA MSC again;
1.3G﹠amp; The C gateway returns response message to CDMA MPC after receiving the response message that CDMA MSC returns;
To agree that positioning short message MO is sent to CDMA MPC by CDMAMSC 1.4 roam to the GSM user of cdma network; Perhaps be sent to G﹠amp by CDMA MSC; The C gateway is if be sent to G﹠amp; The C gateway, then carry out one of following two kinds of steps again:
1) G﹠amp; The C gateway will agree that positioning short message MO exhales short message to be sent to the GSM short message service center that GSM user belongs to as the common beginning; GSM short message service center will agree that the short message MO of location is sent to CDMA MPC by CDMA short message service center, or directly be sent to CDMA MPC.
2) G﹠amp; The C gateway receives when agreeing positioning short message MO, and judging this is a short message MO that is used for positioning service, just sends it to CDMA MPC.
The solution of utilizing the present invention to propose only needs to revise G﹠amp; The handling process of C gateway and CDMA MPC, just can be (if directly send the agreement positioning short message to MPC under the condition of the main switching equipment in not changing or seldom change cdma network and GSM network by CDMA MSC, existing C DMA MSC need judge that this short message is the short message that is used to locate so, and the MSC of existing network does not do this judgement, so need to change.In reality operation, generally can this thing happens.) third party's positioning service of cdma network is provided to the GSM user who roams to cdma network.
