Systems and Methods For a Location Server to Efficiently Obtain Location Information From a Location Management Entity

摘要

In one aspect there is provided a method performed by a first location management entity, LME (e.g., an MME or an SGSN), for providing location information to a location server (e.g., a GMLC). The method includes the first LME receiving from the location server a first request for location information pertaining to a terminal. The method also includes the first LME determining whether the terminal is in a connected state. The method further includes the first LME, in response to determining that the terminal is in a connected state, performing a method comprising: i) transmitting a stop paging message to a second LME; ii) obtaining the requested location information pertaining to the terminal; and iii) transmitting the obtained location information to the location server.

主权项

1. A first location management entity (LME) apparatus, the LME apparatus comprising:
a receiver; a transmitter, and a processing unit, comprising a processor, coupled to the transmitter and receiver, wherein the processing unit is configured such that, in response to the LME apparatus receiving from a location server a request for location information pertaining to a terminal, the processing unit determines whether the terminal is in a connected state in a first RAN to which the LME apparatus is connected, and the processing unit is further configured such that, in response to determining that the terminal is not in a connected state in the first RAN, the processing unit employs the transmitter to transmit to a second LME apparatus connected to a second RAN a location request for causing the second LME apparatus to transmit to the first LME apparatus a response message comprising state information identifying a state of the terminal in the second RAN.
