Embodiment Construction

[0065] For the purposes of the present invention, MT call processing in the GMSC can be divided into two logical parts:

[0066] (1) called processing;

[0067] (2) Roaming branch processing.

[0068] The called process includes obtaining the T-CSI from the HLR and invoking the first CAMEL service. The first CAMEL service may impose call restrictions or may impose call forwarding. In general, the first CAMEL service can also be used to terminate billing for the case of roaming of the called subscriber. HLR can also return other IN trigger elements together with T-CSI.

[0069] Roaming leg processing includes acquiring the MSRN from the HLR and routing the call from the GMSC to the terminating MSC where the called party is registered at that moment. Note that "roaming leg" applies equally to the case where the subscriber is in the visited public land mobile network (VPLMN) and the subscriber is in the home public land mobile network (HPLMN). That is, "roaming" is not assoc...

Abstract

A method and control node (110) and computer program are disclosed for handling Intelligent Network services associated with a call to a subscriber of a mobile telecommunications network, the network comprising said c ontrol node (110), a HLR 5 (111) and one or more SCPs (121, 122, 123). Said control node (110) a) sends (101) to said HLR (111) one or more requests for routing information associated with said call; b) receives (102) from said HLR (111) service trigger elements associated with said services; c) uses said trigger elements for invoking (103) said services in said one ore more SCPs (121, 122, 123); and d) receives (104) from said one or more 10 SCPs (121, 122, 123) information related to said services associated with said trigger elements.

Description

technical field [0001] The invention relates to a method and a control node for handling intelligent network services related to calls to subscribers of a mobile telecommunication network. Background technique [0002] Intelligent network services are well known in current telecommunication network technologies such as GSM (Global System for Mobile Communications). [0003] The central component of the core network subsystem of the GSM network is the Mobile Services Switching Center (MSC). It functions as a switching node similar to PSTN or ISDN and additionally provides all functions required for handling mobile subscribers, such as registration, authentication, location update, handover and call routing to roaming subscribers. These services are provided along with several functional entities, which together constitute the core network subsystem. A Gateway MSC (GMSC) provides connectivity to fixed networks such as PSTN or ISDN. Signaling between functional entities in t...
