  • Patent number: 9674219
    Abstract: There is provided a method of authenticating a public land mobile network (PLMN) to a mobile station (MS). The PLMN provides a circuit switched access network to the MS, and the MS and a trusted service, TS, have established a security context. The initiation of a voice call or initiation of sending or receiving of a pushed message by the MS (S10.1) is detected, and the TS generates a response authentication token using a session identifier and the security context (S10.7). The TS sends a response comprising the response authentication token to the MS such that the response is delivered to the MS over a signalling channel of the PLMN using a mobile subscriber integrated services digital network-number (MSISDN) associated with the subscriber or subscription to direct the message (S10.9). The MS authenticates the response using the response authentication token, the security context, and the session identifier (S10.12) in order to authenticate the PLMN.

  • Patent number: 9596698
    Abstract: The disclosure relates to a method and radio base station for sharing resources in a wireless communication system. The radio base station stores an identity of a first entity to which a first plurality of UEs is associated. The first plurality of UEs has full access to resources provided by the radio base station. The radio base station also stores an identity of a second entity to which a second plurality of UEs is associated. The second plurality of UEs has partial access to the resources provided by the radio base station. When the radio base station receives a request for accessing resources from a UE, it determines whether the UE is associated with the second entity, i.e. if the UE is to be handled in support mode. If the UE is associated with the second entity it means that the UE only should have partial access to the resources.

  • Patent number: 9532283
    Abstract: A telecommunications system comprises a serving radio base station and a candidate radio base station which are different with respect to at least one of frequency and radio access technology. The serving radio base station comprises a radio base station to which a wireless mobile station provides measurement reports. A method comprises the serving radio base station allowing the mobile station to obtain information broadcasted by the candidate radio base station. The information is either information for locating Cell Global Identity (CGI) of the candidate radio base station or the Cell Global Identity (CGI) itself of the radio base station. The mobile station obtains the information from the candidate radio base station during at least one reading gap. The reading gap is a time period in which the mobile station does not receive information from the serving radio base station.
