System and method for updating a sleep id of a mobile station in a bwa communication system

A system for updating a sleep identifier (SLPID) in a broadband wireless access (BWA) communication system, the system comprising:

• a mobile station (MS) in sleep mode operation;
• and
• a base station (BS) for transmitting a message including SLPID update information to the MS when there is no traffic directed to the MS,
• wherein the SLPID update information includes information on an old SLPID allocated to the MS and a new SLPID allocated to the MS for updating the old SLPID, and an SLPID is uniquely assigned by the BS whenever an MS is instructed to enter a sleep mode.

A method for updating a sleep identifier (SLPID), by a mobile station (MS) in sleep mode operation, in a broadband wireless access (BWA) communication system, the method comprising the steps of:

• receiving, from a base station (BS), a message including SLPID update information including information on an old SLPID allocated to the MS and a new SLPID allocated to the MS for updating the old SLPID;
• and
• updating the old SLPID to the new SLPID,
• wherein the message is transmitted when there is no traffic directed to the MS, and an SLPID is uniquely assigned by the BS whenever an MS is instructed to enter a sleep mode.
