Abstract

The invention provides method for infinity registration using a Session Initiation Protocol, SIP, based communication in a Session Initiation Protocol based network, wherein the network comprises at least two or more SIP user agents and wherein each SIP user agent can act as a user agent client, UAC, when requesting a service function and as a user agent server, UAS, when responding to a request service function, the method comprising the steps of: initiating a registration, from the UAC to the UAS, wherein the registration comprises a field for indicating infinity registration capability and a field for indicating management communication capability, sending, from the UAS to the UAC, a registration expiry timer with a value equal to infinity and a management header including a onetime unique token; storing, at the UAC, the onetime unique token in combination with the registered UAC; detecting, at the UAS or UAC, whether loss of a connection between the UAS and the UAC has occurred, if a loss of the connection is detected by the UAC, the UAC initiates a new registration without any indication from the UAS, if a loss of the connection is detected by the UAS, sending, by the UAS to the UAC, a SIP message asking the UAC to initiate a new registration; sending, by the UAS to the UAC, the onetime unique token to refer to the no longer valid registration as indicated during the registration;
