Abstract
In some mobile telecommunications systems reception of calls outside the home network may be very expensive for the called subscriber. For this reason, subscribers are given the possibility to bar incoming calls when roaming outside the home network. On the other hand, when using optimised routing, reception of calls even far from the home network may be very advantageous or even free. Hereby there are no longer any grounds for barring incoming calls. A method is presented in this invention where those network elements can be defined for the subscriber on a location information basis from which incoming calls will be relayed to the subscriber.
Claims16
Method of control of calls in a mobile telecommunications network comprising at least a mobile subscriber, mobile stations and mobile services switching centres (MSC) and wherein
- connections can be set up between mobile stations (MS) and mobile services switching centres,
- mobile services switching centres (MSC) may set up connections with network elements (GMSCA) outside the mobile telecommunications network,
- information is maintained on the subscriber's location,
- characterized in that
- at least one piece of subscriber location information is defined to correspond with a set of allowed network elements (GMSC), and
- when a call is set up:
- the calling subscriber's network element (GMSCA) is compared with the set of allowed network elements (GMSC) relating to the called subscriber's current location, and
- the call is relayed to the called subscriber if the comparison shows that the calling subscriber's network element (GMSCA) belongs to the set of allowed network elements (GMSC).
Mobile telecommunications network comprising at least a mobile subscriber, mobile stations (MS), mobile services switching centres (MSC) and the subscriber's home location register (HLR) comprising storing equipment for storing location information of the mobile subscriber,
- characterized in that the network comprises
- storing equipment for storing at least one piece of information on a set of allowed network elements (GMSC) corresponding with the subscriber's location information,
- comparing equipment for comparing the calling subscriber's network element (GMSCA) with a set of allowed network elements (GMSC) relating to the called subscriber's current location, and
- for the comparing equipment corresponding relaying equipment for relaying the call to the called subscriber, if the comparison shows that the calling subscriber's network element (GMSCA) belongs to the set of allowed network elements (GMSC).
Home location register (HLR) of a mobile telecommunications network where information is stored on the location of the mobile subscriber, characterized in that it comprises
- storing equipment for storing at least one piece of information on a set of allowed network elements (GMSC) corresponding with the subscriber's location information,
- comparing equipment for comparing the calling subscriber's network element (GMSCA) with a set of allowed network elements (GMSC) relating to the called subscriber's current location, and
- for the comparing equipment corresponding control equipment for controlling the call to be relayed to the called subscriber, if the comparison shows that the network element (GMSCA) of the calling subscriber belongs to the set of allowed network elements (GMSC).
Network management system (NMS) of a mobile telecommunications network allowing supply of information to network elements (GMSC) of a mobile telecommunications system,
- characterized in that
- the system is adapted to set up and forward to the network elements such information corresponding with the subscriber's location information, which concerns a set of allowed network elements (GMSC) from which incoming calls are relayed to the called subscriber.
