SYSTEM AND METHOD FOR PROVIDING INFORMATION INDICATING THE PRIORITY LEVEL OF A NON ACCESS STRATUM SIGNALING MESSAGE AND FOR USING THE PRIORITY LEVEL INFORMATION TO SELECT A RESPONSE
First Claim
1. A core network node for use in a wireless communication system, wherein the core network node is operable to:
- receive from a base station a first message comprising a second message that was transmitted by a wireless communication device and received at the base station, wherein the second message comprises a particular type of non access stratum (NAS) message targeted to the core network node;
determine, based on information contained in the first message, a priority level of the received NAS signaling message;
in response to receiving the NAS signaling message, select responsive information to include in a response NAS signaling message, wherein the selection of the responsive information is based at least in part on the determined priority level of the received NAS signaling message; and
transmit to the wireless communication device the response NAS signaling message containing the selected responsive information.

Abstract
A system and method for providing an indication of a priority level of a non access stratum (NAS) message. In one aspect, a wireless communication device transmits a NAS signaling message together with a Packet Flow Identifier (PFI) information element that includes information indicating a priority level of the NAS signaling message. If the NAS signaling message has a low priority, the wireless communication device may receive a response message indicating that the ongoing NAS signaling message scenario can be performed less frequently in the future, thereby mitigating network congestion and radio interference.

8. A method for processing non-access stratum (NAS) messages transmitted by a wireless communication device, comprising:
-
receiving, at a core network node, a first message transmitted from a base station, the first message comprising a second message that was transmitted by the wireless communication device and received at the base station, wherein the second message comprises a particular type of NAS signaling message targeted to the core network node; determining, based on information contained in the first message, a priority level of the received NAS signaling message; in response to receiving the NAS signaling message, selecting responsive information to include in a response NAS signaling message, wherein the selection of the responsive information is based at least in part on the determined priority level of the received NAS signaling message; and transmitting from the core network node to the wireless communication device the response NAS signaling message containing the selected responsive information. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A wireless communication device for use in a wireless communication system, wherein the wireless communication device is operable to:
-
transmit a message comprising a particular type of non access stratum (NAS) message targeted to a core network node and information identifying a priority level of the transmitted NAS signaling message; and receive a response NAS signaling message from the core network node, the response message containing information which is responsive to the transmitted priority information, wherein the wireless communication device is configured such that, prior to receiving the response NAS signaling message, the wireless communication device is configured to transmit the particular type of NAS signaling message at least once every X minutes, and the wireless communication device is configured such that, in response to receiving the response NAS signaling message, the wireless communication device transmits the particular type of NAS signaling message less frequently than once every X minutes. - View Dependent Claims (16, 17)
