Method for implementing a call connection between a non-local calling subscriber and a local called subscriber who is an intelligent network subscriber
First Claim
1. A method for implementing a call connection between a non-local calling subscriber and a local called subscriber who is an intelligent network subscriber, comprising:
- a non-local Gateway Mobile Switching Center (GMSC) initiating a Send Routing Information (SRI) operation to a local Home Location Register (HLR) to request a roaming number of the called subscriber;
the HLR returning a virtual roaming number allocated by the HLR to the non-local GMSC, the virtual roaming number being allocated according to the address of a Service Switch mci Point (SSP) of an intelligent platform;
the non-local GMSC connecting the call to the SSP with the virtual roaming number;
the SSP initiating a SRI operation to the HLR with the virtual roaming number;
after finding a number contained in the SRI operation is a virtual roaming number allocated before, the HLR returning the actual subscriber number (MSISDN) of the called subscriber corresponding to the virtual roaming number and CAMEL Subscription Information (CSI) data of the called subscriber to said SSP; and
the SSP triggering service logic based on said CSI data.

Abstract
The present invention discloses a method for implementing a call connection between a non-local calling subscriber and a local called subscriber who is an intelligent network subscriber. The method comprises the following steps: a. a non-local Gateway Mobile Switching Center (GMSC) initiating a Send Routing Information (SRI) operation to a Home Location Register (HLR) to request the roaming number of the called subscriber; b. the HLR returning a virtual roaming number to the non-local GMSC, and the non-local GMSC connecting the call to a Service Switching Point (SSP) of an intelligent platform according to the virtual roaming number; c. the SSP initiating a SRI operation to the HLR with the virtual roaming number in an Initialize Address Information (IAI) message; d. after finding the number in the SRI operation is a virtual roaming number allocated before, the HLR returning the actual subscriber number corresponding to the roaming number and CAMEL Subscription Information (CSI) data of the intelligent network subscriber corresponding to the actual subscriber number to said SSP; and e. the SSP triggering service logic based on said CSI data, and connecting the call to a Visited Mobile Switching Center (VMSC) corresponding to the called subscriber. With this method, the billing system of mobile intelligent network can be improved.
