Abstract

A method and apparatus for optimizing the use of CPNS entities are discussed. According to an embodiment, a method includes receiving, by a CPNS server, a low battery level indication for an operation from a certain one of CPNS entities; requesting, by the CPNS server, battery level information from at least some of the CPNS entities in response to the low battery level indication; determining, by the CPNS server, life expectancy information for each of the at least some of the CPNS entities based on the battery level information; and transmitting, by the CPNS server, a message to at least one CPNS gateway to use one of the at least some of the CPNS entities instead of the certain one of the CPNS entities to perform the operation, based on the life expectancy information.

Claims

1. A method for optimizing resources of a Converged Personal Network Service (CPNS) enabler, the CPNS enabler including a CPNS server and a plurality of CPNS entities, the plurality of CPNS entities including a CPNS gateway and a plurality of Personal Network Elements (PNEs) including first, second, third and fourth PNEs, the method comprising:

transmitting, by the CPNS gateway to the CPNS server, battery level information of the plurality of PNEs when the first PNE is currently performing a specific service in an active mode with the third PNE;

selecting, among the second PNE and the fourth PNE, a switching PNE to be switched in the first PNE based on the battery level information of the plurality of PNEs or user preference information,

wherein if the CPSN server does not include the user preference information, the switching PNE is selected as the PNE having the higher battery level among the second PNE and the fourth PNE,

wherein if the CPSN server includes the user preference information, the switching PNE is selected based on the user preference information without reference to the battery level information, and

wherein if the CPSN server includes user selection information, the switching PNE is selected based on the user selection information without reference to the battery level information and the user preference information;

receiving, by the CPNS gateway from the CPNS server, an instruction message to switch from the first PNE to the switching PNE for performing the specific service;

transmitting, by the CPNS gateway, a message to wake up to the switching PNE from an idle mode to an active mode;

receiving, by the CPNS gateway, a response message in response to the message to wake up from the switching PNE;

requesting, by the CPNS gateway, data for the specific service from the switching PNE;

in response to the requesting, receiving, by the CPNS gateway, data for the specific service from the switching PNE; and

transmitting, by the CPNS gateway, the received data for the specific service to the third PNE.

2. The method of claim 1, further comprising:

establishing a communication path between the switching PNE and the third PNE through the CPNS gateway; and

allowing the specific service of the switching PNE to be performed at the third PNE through the communication path.

3. The method of claim 1, further comprising:

after receiving the instruction message, transmitting a message to the third PNE prior to transmitting the message to wake up the switching PNE.

4. The method of claim 1, wherein the specific service includes a global positioning system (GPS) service, a multimedia service, or a mobile terminal service.

5. The method of claim 1, wherein the CPNS gateway is a mobile terminal.

6. A Converged Personal Network Service (CPNS) gateway for optimizing resources of a CPNS enabler including a CPNS server and a plurality of CPNS entities, the plurality of CPNS entities including the CPNS gateway and a plurality of Personal Network Elements (PNEs) including first, second, third and fourth PNEs, the CPNS gateway comprising:

a transceiver; and

a processor, cooperating with the transceiver and configured to;

transmit, to the CPNS server, battery level information of the plurality of PNEs when the first PNE is currently performing a specific service in an active mode with the third PNE,

select, among the second PNE and the fourth PNE, a switching PNE to be switched in the first PNE based on the battery level information of the plurality of PNEs or user preference information,

wherein if the CPSN server does not include the user preference information, the switching PNE is selected as the PNE having the higher battery level among the second PNE and the fourth PNE,

wherein if the CPSN server includes the user preference information, the switching PNE is selected based on the user preference information without reference to the battery level information, and

wherein if the CPSN server includes user selection information, the switching PNE is selected based on the user selection information without reference to the battery level information and the user preference information,

receive, from the CPNS server, an instruction message to switch from the first PNE to the switching PNE for performing the specific service,

transmit a message to wake up to the switching PNE from an idle mode to an active mode;

receive a response message in response to the message to wake up from the switching PNE;

request data for the specific service from the switching PNE;

in response to the request, receive data for the specific service from the switching PNE; and

transmit the received data for the specific service to the third PNE.

7. The CPNS gateway of claim 6, wherein the processor is further configured to:

establish a communication path between the switching PNE and the third PNE through the CPNS gateway; and

allow the specific service of the switching PNE to be performed at the third PNE through the communication path.

8. The CPNS gateway of claim 6, wherein the processor is further configured to:

after receiving the instruction message, transmit a message to the third PNE prior to transmit the message to wake up the switching PNE.

9. The CPNS gateway of claim 6, wherein the specific service includes a global positioning system (GPS) service, a multimedia service, and a mobile terminal service.

10. The CPNS gateway of claim 6, wherein the CPNS gateway is a mobile terminal.
