Abstract
A method and control node 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 control node, a HLR and one or more SCPs. Said control node a) sends to said HLR one or more requests for routing information associated with said call; b) receives from said HLR service trigger elements associated with said services; c) uses said trigger elements for invoking said services in said one ore more SCPs; and d) receives from said one or more SCPs information related to said services associated with said trigger elements.
Claims21
A method for handling a call to a subscriber's mobile station of a mobile telecommunications network, the network comprising a control node and a Home Location Register (HLR), the method comprising the steps of the control node:
- sending a Mobile Application Part—Send Routing Information (MAP SRI) to the HLR, the MAP SRI including a Suppress T-CSI flag,
- receive in return a Mobile Application Part—Send Routing Information response (MAP SRI Res) including a Mobile Station Roaming Number (MSRN) and a roaming leg IN category key (RICK) from the HLR;
- and
- using said RICK, together with said Mobile Station Roaming Number in said response, for further handling of a roaming leg of the call.
A control node for handling a call to a subscriber's mobile station of a mobile telecommunications network, the network comprising said control node and a Home Location Register (HLR), the control node comprising:
- a processor, and
- a memory storing instructions that, when executed, cause the control node to:
- send a Mobile Application Part—Send Routing Information (MAP SRI) to said HLR, the MAP SRI including a Suppress T-CSI flag and an indication for support of a roaming leg IN category key (RICK),
- receive in return a Mobile Application Part—Send Routing Information response (MAP SRI Res) including a Mobile Station Roaming Number (MSRN) and a roaming leg IN category key (RICK) from the HLR;
- and
- using said RICK, together with said Mobile Station Roaming Number in said response, for further handling of a roaming leg of the call.
A method for handling a call to a subscriber's mobile station in a mobile telecommunications network, the network comprising a control node and a Home Location Register, the method comprising the steps of the Home Location Register;
- receiving from said control node, one or more Mobile Application Part—Send Routing Information (MAP SRI) requests for routing information associated with said call,
- checking if a Suppress T-CSI parameter is set in said request, and in the affirmative;
- sending a Mobile Application Part—Send Routing Information response (MAP-SRI Res) to said control node including a Mobile Station Roaming Number (MSRN) and a roaming leg IN category key (RICK).
A Home Location Register, for handling a call to a subscriber's mobile station of a mobile telecommunications network, the network comprising said Home Location Register (HLR) and a control node, the control node comprising:
- a processor, and
- a memory storing instructions that, when executed, cause the Home Location Register to
- receive from said control node, one or more Mobile Application Part—Send Routing Information (MAP SRI) requests for routing information associated with said call,
- check if a Suppress T-CSI parameter is set in said request, and in the affirmative;
- send a Mobile Application Part—Send Routing Information response (MAP-SRI Res) to said control node including a Mobile Station Roaming Number (MSRN) and a roaming leg IN category key (RICK).
