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.

Abstract: Key identification techniques for determination of appropriate keys for processing messages in communication systems are provided. In one or more methods, an indicator is assigned to each key pair provisioned in a communication system. The indicator is then sent to one or more network elements or functions in the communication system with a message encrypted with a first part of the key pair corresponding to the indicator. A network element or function receiving the encrypted message determines, based on the indicator, a corresponding second part of the key pair to use to process the encrypted message.

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: The invention relates to a method for recording charges in a communications network with a network node (account node 4) for managing at least one account of a communications subscriber (1) conducted as a credit account and with a network node (recording node 3) for recording the accrued charges. According to the invention, a portion of the account balance is specified as a charge limit. The recording node (3) compares the amount of the charges accrued during the communications connection with the charge limit, and an attainment message (ACR) is sent to the account node when the charges reach the charge limit. In order to also be able to record charges of considerably different amounts, exceed data is generated when the charges are based on an individual request that exceeds the amount of the charge limit, and an increased charge limit is established based on this exceed data.
