Abstract
The present invention relates to a method for locating a wireless terminal device in a cellular network in response to a location request, wherein a quality information is added to the location request in order to define a requested quality of service. Based on the quality of service, a suitable place or network element for determining the location is selected. Thereby, a load sharing model can be provided such that the calculation capacity can be distributed and the signaling load reduced.
Claims20
A method for locating a wireless terminal device in a cellular network in response to a location request, said method comprising the steps of:
- adding a quality information to said location request, said quality information defining a requested quality of service;
- checking said quality information on the transmission path of said location request in said cellular network;
- selecting based on said quality information a network element at which the location of said wireless terminal device is calculated, said network element being selected from network elements of a core network and a radio access network of said cellular network.
A network element, comprising:
- routing means for routing a location request to a determination network element where the location request where the location of a wireless terminal is calculated in response to the location request;
- checking means for checking a quality information added to said location request, said quality information defining a requested quality of service;
- and
- selecting means for selecting said determination network element based on said quality information, said determination network element being selected from network elements of a core network and a radio access network of said cellular network.
A system for locating a wireless terminal device in cellular network in response to a location request, said system comprising:
- a service function for adding a quality information to said location request;
- a network element for selecting based on said quality information a network element where the location of said wireless terminal device is to be calculated and for routing said location request to said selected network element, said selected network element being selected from network elements of a core network and a radio access network of said cellular network;
- and
- wherein said selected network element is configured to receive said location request and to calculate said location in response to said location request.
A network element, comprising:
- a router configured to route a location request to a determination network element where the location request of a wireless terminal is calculated;
- a checking unit configured to check a quality information added to said location request, said quality information defining a requested quality of service;
- and
- a selecting unit configured to select said determination network element based on said quality information, said determination network element being selected from network elements of a core network and a radio access network of said cellular network.
