The present invention discloses a third party registration processing method based on the IMS network, which comprises that a UE completes the registration on a S-CSCF entity; the S-CSCF entity starts a waiting timer; the UE and a P-CSCF entity initiate and complete a registration status subscribing respectively to the S-CSCF entity; the S-CSCF entity initiate a third party registration to an AS when the waiting time of the waiting timer is enough. Through the present invention, the S-CSCF entity performs a waiting after the UE is successfully registered, to make the subscribing success of the registration status of the P-CSCF and the UE take precedence over the third party registration and avoid the situation of conflicting data of the UE, the P-CSCF, the S-CSCF and an HSS, to make the UE, the P-CSCF and the S-CSCF effectively process the abnormal circumstance occurred when the third party registration fails.

The invention discloses a downlink message control method of a star topology network and a server for executing the control method. The star topology network comprises a server, a plurality of gateways and a plurality of nodes. The nodes communicate with the server through the gateway, and the server allocates a timer for each of the gateways. The control method comprises the following steps: 1, judging whether a node is newly accessed to the star topology network; if so, entering the step 2; Step 2, establish a node-gateway topology relationship to determine a coverage area of each gateway and a coverage area of each node; 3, allocating one of a plurality of downlink frequency points to a newly access node; 4, requesting the gateway to send the message request when the frequency requiredfor the message request to be sent by the gateway is not used by the gateway in the coverage area of the destination node of the message request. The invention can more efficiently solve the problem of co-frequency interference of downlink communication of star topology network.
