Embodiment 1

[0135] The network element with redirection query function is GMSC, as shown in Figure 4, including:

[0136] 401. The terminal of the CS domain user is called, and the GMSC of the called terminal receives an IAM request carrying the number of the called user;

[0137] 402. According to the IAM request, the GSMC sends an SRI routing query message to the HSS of the called user;

[0138] 403. Optionally, before returning the route query response message SRI_ACK, the HSS also needs to judge whether the called user has subscribed to a service with a higher priority than the PNM service according to the called user ID and the setting of the service priority. Other supplementary services (Call Barring call blocking, OperatorDetermining Call Barring operator-determined call blocking), when the priority of the other supplementary services is lower than the PNM service or other services have higher priority than the PNM service and are not activated, the HSS sends The GMSC returns the...

Embodiment 2

[0145] When the network element with redirection query function is HSS, as shown in Figure 5, it includes:

[0146] 501. A CS domain user who subscribes to the PNM service is called, and the GMSC of the user receives an IAM request carrying the number information of the called user;

[0147] 502. The GMSC sends an SRI route query message to the HSS;

[0148] 503. The HSS judges whether the user has signed up for the PNM service. If the user has signed up for the PNM service, step 504 is executed.

[0149] Optionally, in the step 503, the HSS also needs to determine whether the user has signed up for other services with higher priority than the PNM service while signing up for the PNM service. If the called user has signed up for the PNM service, the called party When the user has signed other services with a set priority lower than the PNM service, or has not signed other services, or signed a set priority higher than the PNM service and has not been activated, perform step 5...

Embodiment 3

[0194] Referring to Fig. 8, when the network element with redirection query function is the signaling transfer point STP, when the STP and the PNM server are set up together, it includes:

[0195] 801. A CS domain user who has subscribed to the PNM service is called, and its GMSC receives an IAM request carrying the number information of the called user;

[0196] 802. The GMSC sends an SRI routing query message to the HLR / HSS, and the routing query message is intercepted by the STP;

[0197] 803. The STP sends a redirection information query request to the upper-layer PNM server according to the intercepted routing query message, and the PNM server executes the redirection business logic to obtain the redirection information;

[0198] Optionally, the STP also includes before sending the redirection information query message: the STP judges whether the called user has signed up for the PNM service, and if the user has not signed up for the PNM service, the STP will directly for...

Abstract

This invention discloses a method for realizing redirectional service of PNM in circuit domain including the following steps: a NE with RIQF function in a network sends an inquiry message of redirectional information to AS according to a service request it gets, said AS receives the message and generates a redirectinal information based on the set of the user and feeds back it to the NE with said RIQF function, which controls the routes and finally controls the route to the UE determined in the redirectional information. This invention also puts forward a system for realizing PNM service in circuit domain and NE with the RIQF function.

Description

technical field [0001] The invention relates to a communication field, in particular to a technology for realizing PNM redirection services in a circuit domain. Background technique [0002] With the development of communication technology, the UMTS core network is divided into three subsystems: CS, PS, and IMS. Among them, the CS domain (Circuit Switched Domain, circuit switched domain) is used to provide circuit-type services to users. The CS domain includes : MSC (MSC Server / CS-MGW, Mobile Service Switch Center; mobile service switching center server) that completes the switching and signaling control functions of circuit-switched services; GMSC (Gateway MobileSwitching Center, gateway mobile switching center), the GMSC can be set up together with MSC or separately; the circuit domain also includes IWF (Interworking Function; interconnection server), which is closely related to MSC, and completes the PLMN network and ISDN, PSTN, PDN network The intercommunication between...
