MULTIPLE NETWORK CONNECTION METHOD AND COMMUNICATION DEVICE THEREOF

摘要

A multiple network connecting method and its communication device are provided to allow an ME(Mobile Equipment) not to perform a service by way of a UE(User Equipment) so that the ME is not dependent to a communication environment of the UE. A UE#1(100) requests a service from an ME#1(201)(1). The ME#1(201) performs service control in response to the request(2), and then transmits a response message to the UE#1(100)(3). The UE#1(100) performs service control(4). The UE#1(100) requests a service from a PNM(Personal Network Management) AS(Application Server)(520)(5). The PNM AS(520) performs service control in response to the request(6), and then transmits an OK response message to the UE#1(100)(7). The PNM AS(520) transfers a service request to an S-CSCF(Serving-Call State Control Function)(540)(8). The S-CSCF(540) routes the service request to an external service providing entity or UE#2(530)(9). The external service providing entity or UE#2(530) transfers an OK or NO response message to the S-CSCF(540)(10). The S-CSCF(540) transfers the OK or NO response message to the PNM AS(520)(11). The external service providing entity or UE#2(530) generates a connection path(610) with the ME#1(201)(12). The external service providing entity or UE#2(530) transfers service data to the ME#1(201) through the connection path(610)(13)(14).
