ABSTRACT:
The present invention supports a protection path in a radio access network in order to continue communication between terminating nodes of the radio access network if a failure occurs with a communications path between the terminating nodes. A node may assume the functionality of a router, a base transceiver station, or a base station gateway. The establishment of the protection path utilizes the redundancy of connectivity in the radio access network when routing the protection path in accordance with a service protection model. The protection path may be configured with a service protection model that is based on a quality of service model or on a separate protection model. With a quality of service being associated with a traffic class, the service profile indicates the quality of service for different types of services for a user as well as the quality of service that is provided by the protection path if a failure occurs with the communications path.
