First Claim
1. A communications service management method in a communications system comprising a communications network, a first communicating unit and a second communicating unit, said method comprising, during an ongoing communication between said first communicating unit and said second communicating unit using a first communications service, said network initiating a service change from said first communications service to a second communications service based on an estimated communications quality for at least one of said first and second communications service.

Abstract
The invention provides management of alternative services in a communications system (1). A user equipment (300) requests a primary service at the communications network (10) during the setup of a communications session. In addition, at least one possible alternative service to use if the primary service is unavailable is suggested. Radio performance and signaling quality of the bearers of the primary and alternative service(s) are monitored. If the quality deteriorates, the network (10) issues a service change to a less quality demanding alternative service. If the quality subsequently improves, the network (10) can issue a fallback reversion, thus, changing service to a more preferred service, typically the requested primary service.

- 15. A communications service management system in a communications system comprising a first communicating unit and a second communicating unit conducting communication using a first communications service, said management system comprising means for initiating, during said ongoing communication, a service change from said first communications service to a second communications service based on an estimated communications quality for at least one of said first and second communications service.

27. A communications service management system in a communications system comprising a first communicating unit conducting communication with a second communicating unit using a first communications service, said management system comprising:
-
means for storing identifiers of a primary communications service selected by said first communicating unit and of at least one alternative communications service, said first communications service being selected from said primary and said at least one alternative communications service;
means for receiving an estimated communications quality for a communications service selected from said primary and said at least one alternative communications service; and
means for initiating, during said ongoing communication, a service change from said first communications service to a second communications service, selected from said primary and said at least one alternative communications service, based on said received communications quality.
