A method improves mobility and service recovery for a user in a wireless communication network. Service information concerning the user is stored in a registrar. A subscription message is sent from a user terminal to the registrar. A header in the subscription message contains a unique indication. In response to the subscription message containing a unique indication in a header, the registrar returns a notification message to the user terminal. The payload of the notification message includes service information for the user to be used by the user terminal for communication services.

The present invention provides a system and method of calculating a service disruption in a communication network comprising network elements, including nodes connected via links and at least one originating node. Each node is able to detect a failure in an adjacent network element. Upon detection of a failure, a first timestamp is generated. The detecting node generates a release signal which is transmitted, together with the first timestamp, to an originating node which releases the affected connection. The originating node establishes a new connection and initiates a new call. Upon establishing a new connection, a node affected by the failure, which forms a part of the new connection, records a second timestamp. The second timestamp is chosen to reflect, as closely as possible, the actual time of restoration of service in the network. Service disruption is measured as a difference between the first and second timestamps.

A methodology is provided for fault detection and service restoration in a multiservice switch on a per flow basis. An ingress source transmits the same data over each of two redundant cores. An egress receiver selects on a per flow bass which core to utilize. Bi-directional flows are not necessarily grouped together. The basic approach to fault detection is to assume that the two cores are not in lock step, but that the shelves are continually monitoring link flows for control path data as well as user data. The path monitoring is accomplished using a combination of arbiter and aggregator functions found in the service shelves and core interface cards, respectively. The arbiter transmits link test cells to both cores on a per flow basis, wherein the link test cells traverse and are monitored by respective aggregators to and from each core. When an egress arbiter determines that a flow is bad, it initiates a switch to the alternative source core, from which the flow would continue.

Techniques described herein relate to automatic upstream service resumption after downstream system failure. An automatic resumption module may be configured to monitor a downstream endpoint (of a problematic downstream service provider) and determine when it again successfully can process requests by periodically processing inbound requests (e.g., from suspended upstream service providers) and automatically re-enabling upstream endpoints for the suspended upstream service providers in the case of success. The automatic resumption module may start a trickle feed timer for each upstream endpoint to allow messages to be processed at a configured retry rate while the upstream endpoint remains suspended. The trickle feed timer may be configured to start upon the triggering of a circuit breaker for the involved downstream service. When downstream endpoint invocation succeeds, the automatic resumption module can resume all upstream endpoints associated with the downstream endpoint.
