Abstract
A method of performing actions related to handover by a mobile station (MS) in a wireless mobile communication system is disclosed. More specifically, the MS receives information from a base station (BS), wherein the information includes at least one action for performing handover and at least one condition corresponding to the at least one action. Furthermore, the MS transmits a request message to perform the at least one action based on the received information from the BS and receives a response message in response to the request message. Lastly, the MS performs the at least one action according to the received response message.

A method for supporting a sleep mode action of a mobile station (MS) in a wireless mobile communication system, the method comprising:
- receiving, in the MS, a first message from a serving base station (SBS) comprising trigger information, wherein the trigger information includes at least one trigger condition and at least one event action comprising a handover action which is performed upon reaching the at least one trigger condition;
- transmitting, from the MS, a sleep request message to the SBS comprising a first enabled triggered parameter, wherein the first enabled triggered parameter includes a first bitmap comprising a first bit which is set to indicate the handover action is enabled;
- receiving, in the MS, a sleep response message from the SBS comprising a second enabled triggered parameter, wherein the second enabled triggered parameter includes a second bitmap comprising a second bit which is set to indicate the handover action is enabled;
- entering, by the MS, a sleep mode after receiving the sleep response message;
- transmitting, from the MS, a handover request message to the SBS when the at least one trigger condition corresponding to the handover action is reached in the sleep mode;
- and
- receiving, in the MS, a handover response message from the SBS in response to the handover request message.
A method for supporting a sleep mode action at a base station (BS) in a wireless mobile communication system, the method comprising:
- transmitting, from the BS, a first message to a mobile station (MS) comprising trigger information, wherein the trigger information includes at least one trigger condition and at least one event action comprising a handover action which is performed upon reaching the at least one trigger condition;
- receiving, in the BS, a sleep request message from the MS comprising a first enabled triggered parameter, wherein the first enabled triggered parameter includes a first bitmap comprising a first bit which is set to indicate the handover action is enabled;
- transmitting, from the BS, a sleep response message to the MS comprising a second enabled triggered parameter, wherein the second enabled triggered parameter includes a second bitmap comprising a second bit which is set to indicate the handover action is enabled;
- receiving, in the BS, a handover request message from the MS when a trigger condition corresponding to the handover action is reached in a sleep mode;
- and
- transmitting, from the BS, a handover respond message to the MS in response to the handover request message.
A mobile station performing a sleep mode action in a wireless mobile communication system, wherein the mobile station is configured for:
- receiving a first message comprising trigger information from a base station (BS), wherein the trigger information includes at least one trigger condition and at least one event action comprising a handover action which is performed upon reaching the at least one trigger condition;
- transmitting a sleep request message to the BS comprising a first enabled triggered parameter, wherein the first enabled triggered parameter includes a first bitmap comprising a first bit which is set to indicate the handover action is enabled;
- receiving a sleep response message from the BS comprising a second enabled triggered parameter, wherein the second enabled triggered parameter includes a second bitmap comprising a second bit which is set to indicate the handover action is enabled;
- entering a sleep mode after receiving the sleep response message;
- transmitting a handover request message to the BS when the at least one trigger condition corresponding to the handover action is reached in the sleep mode;
- and
- receiving a handover response message from the BS in response to the handover request message.
A base station (BS) supporting a sleep mode action of a mobile station (MS) in a wireless mobile communication system, wherein the base station is configured for:
- transmitting a first message to the MS comprising trigger information, wherein the trigger information includes at least one trigger condition and at least one event action comprising a handover action which is performed upon reaching the at least one trigger condition;
- receiving a sleep request message from the MS comprising a first enabled triggered parameter, wherein the first enabled triggered parameter indicates a handover action;
- transmitting a sleep response message to the MS comprising a second enabled triggered parameter, wherein the second enabled triggered parameter indicates the handover action;
- receiving a handover request message from the MS when a trigger condition corresponding to the handover action is reached in a sleep mode;
- and
- transmitting a handover response message to the MS in response to the handover request message.
