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

摘要

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.

主权项

1. A core network node for use in a wireless communication system, the core network node comprising:
one or more network interfaces for receiving 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) signaling message targeted to the core network node; and a data processing system for (i) determining, based on information contained in the first message, a priority level of the received NAS signaling message; and (ii) selecting responsive information to include in a response NAS signaling message in response to receiving the 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; wherein the one or more network interfaces are further for transmitting to the wireless communication device the response NAS signaling message containing the selected responsive information.
