1. A method for executing on a mobile device a protocol session with a location server using a protocol with mechanisms that allow for transport of protocol messages over a non-reliable link, the method comprising:

  • sending a first protocol session message associated with a first protocol session to the location server;

    entering a wait-for-acknowledgement state in which uplink transmissions from the mobile device to the location server are suspended while waiting for an acknowledgement from the location server in response to the first protocol session message;

    receiving a second protocol session message associated with a second protocol session, the second protocol session message not being the acknowledgement from the location server in response to the first protocol session message, the second protocol session message including information requested in the first protocol session message;

    exiting the wait-for-acknowledgement state responsive to receiving the second protocol session message; and

    performing an action using the information received in the second protocol session message.
