摘要： A method for implementing an IP Multimedia Subsystem (IMS) registration, includes: a Home Subscriber Server (HSS) recording a current registration state of a User Equipment (UE) in response to receiving a Multimedia Authentication Request (MAR) initiated by a Service Call Session Control Function (S-CSCF) selected for the UE when a first Register request is sent by the UE; in response to receiving a second Register request initiated by an Interrogating Call Session Control Function (I-CSCF), the HSS sends the S-CSCF Name to the I-CSCF when the current registration state of the UE is an assigned S-CSCF state. By the scheme, a same S-CSCF is ensured to be used in the two User Authentication Request/User Authentication Answer (UAR/UAA) procedures of the initial IMS registration procedure, and the initial IMS registration of the UE is implemented successfully.

摘要： A method, an apparatus, a device, and a system for generating a Dynamic Host Configuration Protocol snooping (DHCP) Snooping binding table. The method includes: constructing a request packet for obtaining information about a DHCP client, and sending the request packet to a DHCP server; receiving a response packet corresponding to the request packet, and extracting the information about the client from the response packet, where the information about the client includes the client's Internet Protocol (IP) address and Media Access Control (MAC) address; and obtaining the client's virtual local area network (VLAN) number and ingress port number through the MAC address, and generating the DHCP Snooping binding table. The technical solutions solve the problem that traffic of some clients is lost due to a lack of a DHCP Snooping binding table of these clients in a process of enabling DHCP Snooping.

摘要： A method for authenticating an IP phone and negotiating a voice domain includes receiving an authentication request packet sent by an IP Phone, encapsulating a user name and password of the IP Phone in a RADIUS request packet, and sending the RADIUS packet encapsulating the user name and password of the IP Phone to a RADIUS server. If a result of the authentication performed by the RADIUS server on the IP Phone is that the authentication succeeds, sending a Voice VLAN value to the IP Phone through an extensible authentication protocol EAP extension packet. In the present application, dynamic security authentication and negotiation functions between a client and a server, and rapid deployment of an internal network of an enterprise may be implemented.
