Abstract

A method of communicating data in a wireless communication system is disclosed. More specifically, a method discloses transmitting a request by a mobile subscriber station (MSS) to a network entity via a de-registration request message requesting the network entity to retain a preferred session information, and receiving a selected session information via a de-registration command response from the network entity.

Claims

1-86. -86. (canceled)

87. A method of communicating data for performing network re-entry of a mobile station (MS) in a wireless communication system, the method comprising:

transmitting, from the MS to a first network entity, a deregistration request message comprising first idle-mode retain information to request for a paging controller to retain MS service and operation information to expedite a future network re-entry from an idle mode;

receiving, from the first network entity at the MS, a deregistration command message comprising second idle-mode retain information to notify the paging controller'"'"'s retention of the MS service and operation information;

deregistering from the first network entity and entering the idle mode; and

performing a network re-entry with a second network entity based on the MS service and operation information retained by the paging controller.

88. The method of claim 87, wherein the first network entity is a serving base station.

89. The method of claim 87, wherein the second network entity obtains the second idle-mode retain information via a backbone network.

90. The method of claim 87, wherein the deregistration request message includes a request to initiate the idle-mode.

91. The method of claim 87, wherein the first idle-mode retain information and the second idle-mode retain information relate to at least one of security, network address, MS capability, management connection identification, and network service maintenance.

92. The method of claim 91, wherein each of the first and the second idle-mode retain information is associated with a capability of the MS which is indicated by Bit#0, with security information which is indicated by Bit#1, with registration information which is indicated by Bit#2, and with network address which is indicated by Bit#3.

93. The method of claim 92, wherein Bit#0 relates to retaining of service and operational information associated with SBC-REQ/RSP messages, Bit#1 relates to retaining of service and operational information associated with PKM-REQ/RSP messages, Bit#2 relates to retaining of service and operational information associated with REG-REQ/RSP messages, and Bit#3 relates to retaining of service and operational information associated with network address.

94. A method of communicating data for expediting a network re-entry of a mobile station (MS) in a wireless communication system, the method comprising:

receiving, from the MS at a first network entity, a deregistration request message comprising first idle-mode retain information to request for a paging controller to retain MS service and operation information to expedite a future network re-entry from an idle mode;

transmitting, from the first network entity to the MS, a deregistration command message comprising second idle-mode retain information to notify the paging controller'"'"'s retention of the MS service and operation information; and

deregistering with the MS such that the MS enters the idle mode,

wherein the MS service and operation information retained by the paging controller is used for the MS to perform the network re-entry with a second network entity.

95. The method of claim 94, wherein the first network entity is a serving base station.

96. The method of claim 94, wherein the second network entity obtains the second idle-mode retain information via a backbone network.

97. The method of claim 94, wherein the first idle-mode retain information and the second idle-mode retain information relate to at least one of security, network address, MS capability, management connection identification, and network service maintenance.

98. The method of claim 94, wherein each of the first and the second idle-mode retain information is associated with a capability of the MS which is indicated by Bit#0, with security information which is indicated by Bit#1, with registration information which is indicated by Bit#2, and with network address which is indicated by Bit#3.

99. The method of claim 98, wherein Bit#0 relates to retaining of service and operational information associated with SBC-REQ/RSP messages, Bit#1 relates to retaining of service and operational information associated with PKM-REQ/RSP messages, Bit#2 relates to retaining of service and operational information associated with REG-REQ/RSP messages, and Bit#3 relates to retaining of service and operational information associated with network address.
