Abstract
The present invention provides a method for obtaining the number of an integrated service digital network of a mobile subscriber. An SGSN judges whether the number of the integrated service digital network of the mobile subscriber (MSISDN) exists locally after interface signaling connection between a radio network controller (RNC) and a serving GPRS support node (SGSN) is completed. If the number of the integrated service digital network of the mobile subscriber (MSISDN) exists locally, processing is not performed, and otherwise, the MSISDN number of the mobile subscriber is obtained by the SGSN from a home location register (HLR). The MSISDN number of the mobile subscriber is sent to the RNC by the SGSN, wherein three kinds of methods can be adopted for sending the MSISDN number of the mobile subscriber to the RNC by the SGSN, that is to say, a method which is provided with a pair of request/response messages for obtaining the MSISDN number of the mobile subscriber, a method which utilizes an added public ID message for recording the MSISDN number, or a method which utilizes that the MSISDN is directly recorded in a subscriber identity cell of the permanent non-access layer of the public ID message. The RNC can realize the purpose of obtaining the MSISDN number of the mobile subscriber by applying the proposal of the present invention.
Description
Technical field
The present invention relates to mobile communication technology, particularly relate to a kind of method of obtaining mobile user comprehensive service digital net number.
Background technology
Along with development of internet technology, universal mobile telecommunications system (UMTS) no longer has been confined to common voice service, and can provide more and more abundanter class of business for people, and such as: multimedia short message service, PS domain video stream business, visual telephone service or the like.
Fig. 1 is a typical UMTS communication system architecture figure.As shown in Figure 1, UMTS generally comprises:
Subscriber equipment (UE, User Equipment) is used for making a call and receipt of call by air interface.
Land radio access web (UTRAN, UMTS Terrestrial Radio Access Network) is used to handle all and the business of wireless relevant function.Land radio access web generally comprises again: and radio network controller (Radio Network Controller, RNC) and base-station node (NodeB).Wherein, RNC is used for being responsible for distributing with control being attached thereto or relevant NodeB resource, mainly finishes functions such as connecting foundation, disconnection, switching, the merging of grand diversity, RRM; NodeB is used to be responsible for finishing the conversion of the data flow between the interface.
Core net (CN, Core Network) is used for be responsible for handling that all voice calls are connected with data in the UMTS system, and the exchange of realization and external network and routing function.CN can be divided into circuit commutative field (CS, Circuit Switched) and packet-switched domain (PS, Packet Switched) again from logic.Wherein, the CS territory provides Circuit Service, connects public switch telephone network circuit-switched networks such as (PSTN); And the PS territory provides Packet data service, connects outer public data networks (PDN, Public DataNetwork) such as Internet.The PS territory of core net comprises service universal grouping wireless business supporting node (SGSN, ServingGPRS Support Node) and ggsn (GGSN, Gateway GPRSSupport Node).SGSN is responsible for functions such as completing place management, mobile model management and tunnel management.GGSN provides route and the encapsulation of packet between UMTS net and external data network, mainly finishes subscription authentication, IP address assignment, UMTS session management etc.
In general, UMTS roughly may further comprise the steps for the business service that the user provides: the user connects by UTRAN and CN; CN carries out authentication or authentication to the user, and when authentication or authentication success, CN sends to the user with the business datum that the user needs by UTRAN, realizes business service; Otherwise CN returns the message that can't provide professional by UTRAN to the user.
Certainly, each business service all has self concrete realization flow, and is more more complex than above-mentioned processing procedure.But no matter be which kind of business, CN generally can obtain international mobile subscriber identity (IMSI) or the mobile user comprehensive service digital net number (MSISDN) of UE, utilizes IMSI or MSISDN that the user is carried out authentication process then.Certainly, CN also may use IMSI or MSISDN in other handling process, such as: the user experience business service is chargeed etc.
In actual applications, the business that UMTS provides for the user also may not be to be that core is handled with CN, but is core with RNC, such as: cell multimedia broadcast (CMB) business.The basic thought of CMB business is: increase a multimedia administration center (MMC) in the UMTS system, be mainly used in storage CMB business datum, and this CMB business datum sends to SGSN by MMC, send to RNC by SGSN again.When the user needs UMTS that the CMB business service is provided, the CMB that RNC detects UE inserts request, finish RAB (RAB) again, the connection of CMB user's face transmission control protocol (TCP) and real time streaming protocol (rtsp) is set up, RNC sends to UE with the CMB business datum then, realizes the CMB business service.
Wherein, CN need not to discern CMB user, and promptly for CN, the CMB business is conductively-closed, has only RNC just CMB user to be discerned.In this case, utilize MSISDN that certain CMB user is carried out authentication, charges and handle if desired, just need RNC that this CMB user's Mobile Subscriber International ISDN Number is provided to CMB authentication and charging center.
But, there is not user's Mobile Subscriber International ISDN Number in RNC itself, the 3GPP agreement does not provide RNC how to obtain the effective ways of mobile subscriber's Mobile Subscriber International ISDN Number yet, thereby mobile subscriber's Mobile Subscriber International ISDN Number can't directly be provided by RNC, also just can't in the business that with RNC is core, utilize MSISDN to realize processes such as subscription authentication, charging.
This shows in the prior art, when needs provide Mobile Subscriber International ISDN Number by RNC, also do not have a kind of effective ways that obtain MSISDN by RNC.
