Abstract: A measurement report is sent from user equipment in a communication system to a serving base station in a serving cell of the communication system, wherein the measurement report comprises one or more signal measurements obtained by the user equipment for one or more other base stations in the communication system. A base station removal list is received at the user equipment from the serving base station which lists any base stations from the measurement report that failed a set-up procedure and are thus potentially false base stations. Any base stations in the base station removal list are removed from consideration by the user equipment as a target base station for a handover procedure.

Abstract: Privacy management techniques for communication systems are provided. In one or more methods, one or more cryptographic key pairs are provisioned in a home network of a communication system for utilization by subscribers of the home network to conceal subscriber identifiers provided to access points in the communication system. The cryptographic key pairs are managed utilizing an element or function in the home network of the communication system. In one or more other methods, one or more public keys associated with one or more cryptographic key pairs are stored in user equipment, the cryptographic key pairs being provisioned by a home network of a communication system for use by subscribers of the home network to conceal subscriber identifiers provided to access points in the communication network. An element or function of the home network of the communication system is interfaced for management of the public keys stored in the user equipment.

Abstract: One or more application programs are invoked at user equipment. At least one of the one or more application programs is configured with application layer security between the user equipment and a data network. A data session request is sent from the user equipment to a communication network. The communication network is configured to connect the user equipment to the data network in association with the at least one application program. The data session request comprises an indication that application layer security between the user equipment and the data network is active for the at least one application program. In one example, in response to the request, the user equipment receives a configuration message indicating that no communication network level security applies for data associated with the at least one application program.

Abstract: In a communication system comprising a first network operatively coupled to a second network, wherein the first network comprises a first security edge protection proxy element operatively coupled to a second security edge protection proxy element of the second network, a method comprises provisioning at least a given one of the first and second security edge protection proxy elements with configuration information that enables the given security edge protection proxy element to identify at least one security operation to be applied to at least one information element in a received message before sending the message to the other one of the first and second security edge protection proxy elements.

Abstract: Techniques for providing privacy features in communication systems are provided. For example, a message may be provided from user equipment to an element or function in a communication network that comprises one or more privacy indicators, where privacy features for processing the message are determined based on the privacy indicators. The message may comprise an attach request comprising a subscription identifier for a subscriber associated with the user equipment, with the privacy indicators comprising a flag indicating whether the subscription identifier in the attach request is privacy-protected. As another example, the element of function in the communication network may determine privacy features supported by the communication network and generate and send a message to user equipment comprising one or more privacy indicators selected based on the determined privacy features. The privacy indicators may comprise an indication of whether the communication network is configured for handling privacy-protected subscription identifiers.
