Embodiments herein relate to a 3rd Generation Partnership Project, 3GPP, infrastructure node, a method in the 3GPP infrastructure node, 3GPP Access, Authorization, and Accounting, AAA server, a method in the 3GPP AAA server, a Home Subscriber Server, HSS and a method in the HSS. More particularly the embodiments herein relate to handling a UE requesting access to a service via an untrusted non-3GPP network. According to a first aspect, a method performed by a 3GPP node for handling a UE, requesting access to a service via an untrusted non-3GPP network is provided. The method comprises checking if trusted 3GPP network location information associated with the UE is available to the 3GPP node from a subscriber database or if the available trusted 3GPP network location information is obsolete. If the trusted 3GPP network location information is unavailable or obsolete, the method comprises determining to use untrusted non-3GPP network location information previously received from the 3GPP AAA server or to derive the untrusted non-3GPP network location information at the 3GPP node. Still further, the method comprises determining if the UE is allowed or barred to access the service via the untrusted non-3GPP network based on the received or derived untrusted non-3GPP network location information. The embodiments herein, relate also to corresponding methods performed in an 3GPP Access, Authorization, and Accounting, AAA server, and a Home Subscriber Server, HSS, respectively. Further, the embodiments herein relate also to corresponding 3GPP infrastructure node, 3GPP AAA server, and HSS.

Methods and nodes for handling access to a service via an untrusted non-3GPP network

A method of managing subscriber mobility within a telecommunications system having at least first and second access domains supporting respective different access technologies. Each of the access domains comprises one or more mobility management gateways responsible for mobility management within the access domain. The method comprises receiving at a first subscriber server within said system, an update location request from a mobility management gateway within said first access domain, the first subscriber server being responsible for said first access domain. A common user database is then updated to update a profile of a subscriber to which said update location request relates in order to record said mobility management gateway within said first access domain as a current location of the subscriber. At said common user database, a notification rule set is applied to the subscriber profile to determine whether or not a notification to cancel a location for said subscriber must be sent to a mobility management gateway within said second access domain. If so, then a notification is sent from said common user database to a second subscriber server within said system, the second subscriber server being responsible for said second access domain. The notification is received at said second subscriber server, and a cancel location request sent to said mobility management gateway within said second access domain. A further update of said subscriber profile in the common user database is performed to remove said mobility management gateway within said second access domain as a current location of the subscriber.

Mobility management in a communications system

Network signalling apparatus and methods use at least an SCCP protocol layer of Signalling System number 7 (SS7) and other protocol layers. The SCCP protocol layer supports connectionless and connection-oriented protocol services, and network management procedures are carried out on a per protocol service basis, that is, network management procedures at SCCP are independently treated for connectionless and for connection-oriented protocol services.
