Abstract:
1. In a data communication system including a plurality of network devices, wherein the plurality of network devices includes first and second network devices, and wherein during initialization, communication system resources for carrying out sessions based services are registered with and allocated by the second network device, a method for providing dynamic services comprising the steps of: receiving during initialization at the second network device a registration message from the first network device containing parameters associated with a plurality of capabilities of the first network device used for carrying out at least one deferred session-based service between at least one service device associated with the first network device and a service server associated with the second network device, wherein each of the at least one deferred-session-based service comprises a service for which communication system resources are registered with, but not allocated by the second network device until the at least one deferred session-based service is later activated, and activation of the at least one deferred-session-based service is operable to occur after a session is established between the first and second devices; configuring the second network device and the service server for the at least one deferred-session-based service; associating a deferred-inactive-service identifier with the at least one deferred-session-based service, wherein the deferred-inactive-service identifier is used to activate the at least one deferred-session-based service at the later time; sending the deferred-inactive-service identifier to the first network device, wherein when the at least one deferred-session-based service is later activated, a communication link utilizing the parameters is established between the first and second network devices receiving at the second network device from the first network device the deferred-inactive-service identifier; responsive to the deferred-inactive-service identifier, activating the at least one deferred-session-based service between the session server and the service device; and changing the deferred-inactive-service identifier to a deferred-active-service identifier.
