A system for implementing a redirection service, characterized by comprising User Equipments, UEs, a Serving Call Session Control Function, S-CSCF, in an Internet Protocol Multimedia Core Network Subsystem, IMS, and a Personal Network Management Application Server. PNM AS, connected to a Personal Network, PN, and connected to the S-CSCF, wherein, the S-CSCF comprises: a redirection trigger unit, used to invoke a terminating call service control logic to process an initial request message of a terminating call of a UE in the Personal Network, PN, to match with initial filter criteria, and to route the initial request message to the PNM AS; and a redirection processing unit, used to uniquely locate a configured UE, showing same Public User Identity, PUI, with a couple of UEs in the PN, according to an identity or both the identity and the PUI in a redirected initial request message, as a terminating call message for the configured UE, after receiving the redirected initial request message, and to invoke the terminating call service control logic to process the redirected initial request message for the teminating call of the configured UE; the PNM AS comprises: a storage unit, used to store a Private User Identity, PVI, the PUI, the identity and registration state information of UEs, comprising the configured UE, in the PN, as well as indication information of configured UEs in the PN; and a redirection control unit, used to add an identity of the configured UE into the initial request message, routed by the S-CSCF, to generate the redirected initial request message and send the redirected initial request message to the S-CSCF when determining to further route the initial request message, routed by the S-CSCF, to the configured UE according to a configuration of the PN; thereby redirecting the initial request message to the configured UE a redirection trigger unit, used to invoke a terminating call service control logic to process an initial request message of a terminating call of a UE in the Personal Network, PN, to match with initial filter criteria, and to route the initial request message to the PNM AS; and a redirection processing unit, used to uniquely locate a configured UE, showing same Public User Identity, PUI, with a couple of UEs in the PN, according to an identity or both the identity and the PUI in a redirected initial request message, as a terminating call message for the configured UE, after receiving the redirected initial request message, and to invoke the terminating call service control logic to process the redirected initial request message for the teminating call of the configured UE; the PNM AS comprises: a storage unit, used to store a Private User Identity, PVI, the PUI, the identity and registration state information of UEs, comprising the configured UE, in the PN, as well as indication information of configured UEs in the PN; and a redirection control unit, used to add an identity of the configured UE into the initial request message, routed by the S-CSCF, to generate the redirected initial request message and send the redirected initial request message to the S-CSCF when determining to further route the initial request message, routed by the S-CSCF, to the configured UE according to a configuration of the PN; thereby redirecting the initial request message to the configured UE a storage unit, used to store a Private User Identity, PVI, the PUI, the identity and registration state information of UEs, comprising the configured UE, in the PN, as well as indication information of configured UEs in the PN; and a redirection control unit, used to add an identity of the configured UE into the initial request message, routed by the S-CSCF, to generate the redirected initial request message and send the redirected initial request message to the S-CSCF when determining to further route the initial request message, routed by the S-CSCF, to the configured UE according to a configuration of the PN; thereby redirecting the initial request message to the configured UE
