Method of operating a gateway with a location information system

A method of operating a gateway with a location information system, comprising the steps of:

• a) receiving a plurality of location request messages from a plurality of client terminals for location information of a mobile terminal, and storing the location request messages in a memory;
• and
• b) making a search through said memory at periodic intervals for detecting at least one location request message, requesting the location information of said mobile terminal from said location information system if there is at least one location request message is detected in said memory, and transmitting a reply message to the client terminal from which said detected message is received and deleting the detected message from the memory.

A gateway for a location information system, comprising:

• a memory;
• and
• a processor for receiving a location request message from a client terminal for location information of a mobile terminal, storing the request message in said memory, acquiring the location information from said system, receiving and storing a further location request message from other client terminal in said memory if the further location request message is requesting location information of said mobile terminal, transmitting the acquired message to said client terminals in response to receipt of the location information from said system, and deleting the stored request messages from said memory.
