Abstract
Official abstract text for this publication.
A method for allowing distribution of congestion-related information between a cellular communication system supporting circuit-switched services and a cellular communication system supporting packet-switched services. A message destined for the packet-switched communication system is identified at the circuit-switched communication system, and congestion-related information, indicating the present congestion status of the circuit-switched communication network is included into the message. The message is then forwarded to a network node of the packet-switched communication system, where either a user equipment or the network node of the first cellular communication system can control Circuit-switched Fallback (CSFB) attempts towards the second communication system on the basis of the congestion-related information prior to having to initiate any access signaling associated with the CSFB attempts.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method in a network node of a first cellular communication system supporting packet-switched services for handling signaling transported between the first cellular communication system and a second cellular communication system supporting circuit-switched services, the method comprising: receiving a message transmitted from the second cellular communication system and recognizing that the message comprises congestion-related information that is indic…
