Title:
AN ARRANGEMENT AND A METHOD FOR OPERATOR ASSIGNMENT IN A SHARED NETWORK ENVIRONMENT
Document Type and Number:
WIPO Patent Application WO/2005/109936
Kind Code:
A1
Abstract:
The present invention relates to an arrangement for assigning core network operator to a mobile user station (UE), e.g. a roaming mobile user station not supporting a functionality of extended broadcast information for shared networks, in a shared network environment wherein different core network operators share a radio network. Each core network comprises a number of core network nodes and supports a redirection functionality for redirecting mobile user stations to find the appropriate core network operator. it comprises a caching arrangement in or associated with a node. In said caching arrangement identification information, e.g. IMSI or MSISDN or IMEI, of a mobile user station, requesting to be registered, is stored. Further information is stored about to which operators an attach request has been sent, such that for subsequent attach requests from the same mobile user station during a mobile user station retry period, said information about identification information and operators is used at subsequent selections of operators during the mobile user station retry period to prevent unnecessary reselection of an already tried operator or core network node.
