  • the Session Initiation Protocol is a protocol defined by IETF RFC3261 for establishing a multimedia session.
  • SIP Session Initiation Protocol
  • the SIP protocol is widely used in packet networks including Internet networks and IMS networks.
  • the IMS network is a service network in which 3GPP R5 and R6 use SIP architecture as a variety of access technologies such as 3G/2G GPRS and WLAN.
  • SIP creates a binding relationship for the location service of the specific domain through the registration service, and the registration service binds the contact address of the Contact header field and the record address in the To header field.
  • a record address can be bound to one or more contact addresses.
  • the proxy server in the domain receives a SIP request, it finds the contact address registered by the user according to the record matching between the Request-U I and the record address in the request, wherein the Request-URI is used to indicate which one to subscribe to.

  • the registration server returns a response message, accepts the subscription request, and at this point, the subscription session is established. 3. After the subscription session is established, the registration server sends a notification message to the application server to notify the registration status of the currently subscribed user terminal.

  • the subscription network element such as the P-CSCF and the AS needs to periodically send a subscription request during the registration lifetime of the user to maintain the validity of the subscription, thereby increasing the overhead of the network device. For example, if a device supports 100,000 users, and each user has three ASs providing services, then each user needs 5 subscription instances, the subscription period is 30 minutes, and the entire device requires 500,000 subscription instances, which need to be processed every second. 28 subscription transactions. This has very high requirements on the memory and performance of communication devices.
