  • Patent number: 10182053
    Abstract: 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is available to the 3GPP node from a subscriber database or if the available trusted 3GPP network location information is obsolete.

  • Patent number: 9648019
    Abstract: The embodiments herein relate to a method performed by an AAA server (113) for enabling a non-SIM device (101b) to access a first network (100a) via a second network (100b). Based on a request for authorization to the first network (100a) from the non-SIM device (101b), the AAA server (113) obtains an identity associated with the non-SIM device (101b). The AAA server (113) transmits a request for a user profile associated with a user of the non-SIM device (101b) to the subscriber database (110). The request comprises the obtained identity for the non-SIM device (101b). The AAA server (113) receives, from the subscriber database (110), the requested user profile for the non-SIM device (101b). Based on the received user profile, the AAA server (113) authorizes the non-SIM device (101b) to access the first network (100a) via the second network (100b).

  • Patent number: 9344923
    Abstract: The present invention is aimed to carry out an effective handover between a first and a second serving call control servers in order to fit suitable server capabilities for servicing a user, as well as to provide a mechanism whereby a subscriber server may upgrade the selection criteria for assigning the second serving call control server. Therefore, the present invention provides a new method and enhanced servers for re-assigning the second serving call control server, whereby the still ongoing sessions for the user in the first serving call control server are kept alive, and where a serving call control server is arranged to report towards the subscriber server what portions of a user profile are not understood or not supported at said serving call control server.

  • Patent number: 7027582
    Abstract: The present invention provides an efficient way of resolving telephone numbers and other entity/device identifiers into Internet addresses as well as accommodating portability of those telephone numbers and other entity/device identifiers without having to substantially modify or rework the domain naming system (DNS) infrastructure or established number portability schemes. Self-contained, additional functionality is implemented on a DNS server which allows smooth IP address resolution of telephone numbers or other entity/device identifiers by taking advantage of existing portability databases without impacting the existing networks that create and maintain such portability databases.

  • Patent number: 6839421
    Abstract: An efficient interface for service exchange is provided between a circuit-switched communications network and a domain naming system (DNS) in a packet-switched communications network. A node in the circuit-switched communications network receives from a first entity a request for a first service involving a second entity associated with a second entity identifier. A message is sent from the circuit-switched network node to a DNS server in the packet-switched network requesting a second service related to the second entity identifier. The result of the second service from the DNS server is used in providing the first service.

  • Patent number: 6611584
    Abstract: In a telecommunication network a subscriber connected to an originating local exchange requests activation of a supplementary service. The supplementary service establishes an end-to-end TC-dialogue with a corresponding supplementary service of a destination local exchange. The TC-dialogue terminates the request on an interfering telecommunication service in an intermediate node. For preventing service operation failure in case of interaction between the supplementary service and the interfering telecommunication service, a relay link is established between an incoming TC-dialogue and an outgoing TC-dialogue at the intermediate node to realize a chain of end-to-end TC-dialogues between the originating exchange and the destination exchange, while using a transparent relay functionality independent of utilizing TCAP based supplementary service ASEs as intermediate nodes.

  • Patent number: 5742673
    Abstract: A generic service coordination mechanism solves feasible service interaction problems taking into account real-time processing constraints within telecommunication networks. The coordination mechanism limits service interaction complexity within an active basic call by preventing interactive service accessibility as early as possible following the request of a new service. Data defined on the basis of a general allocation, an individual subscriber allocation, and a service allocation is manipulated during provision and withdrawal, activation and deactivation, and invocation and operation of service procedures. Requests to initiate, read, change, or erase subscription and interaction data are processed internally according to a coordinator state machine. Requests are terminated by a response which includes a decision to continue basic call processing and service processing based on allocated services and encountered service interaction criteria such as restriction or dependency criteria.
