Abstract: A basestation in a cellular communications network is operable to send a message to a Mobility Management Entity, relating to a suspension or resumption of a connection of a UE, wherein the message contains key renewal information. The Mobility Management Entity receives the message, and determines whether a key renewal condition is met. If the key renewal condition is met, the MME forwards a new NH, NCC pair to the base station. If a message received from the MME includes a NH, NCC pair, the basestation derives keying information using the NH, NCC pair for future use in deriving keys.

Abstract: A device receives a privacy template from a network node. The device forms a temporary privacy mask using a time-varying value and the privacy template; and encrypts a code value using the temporary privacy mask. The device transmits the encrypted code value. A receiving device receives an encrypted code value, and forms a temporary privacy mask using a time-varying value and a privacy template that it has also received from a network node. The receiving device is then able to decrypt the code value using the temporary privacy mask. The code may identify an individual or a group, and may be protected using a privacy template that is specific to the individual or to the group.

Abstract: A terminal device, for example a 3GPP Proximity Services (ProSe) -enabled user equipment, obtains imprecise location information relating to a location of the terminal device, and transmits a proximity service discovery message, wherein the discovery message includes the imprecise location information. A second terminal device, again for example a 3GPP Proximity Services (ProSe) -enabled user equipment, receives a proximity service discovery message containing location information. The second terminal device obtains location information relating to its location, and calculates a distance from the location indicated by the location information in the received discovery message to its location. The second terminal device acts on the received discovery message only if the calculated distance is less than a predetermined distance.

Abstract: Methods for cryptographic synchronization of data packets. A roll-over counter (ROC) value is periodically appended to and transmitted with a data packet when a function of the packet sequence number equals a predetermined value. The ROC effectively synchronizes the cryptographic transformation of the data packets. Although the disclosed methods are generally applicable to many transmission protocols, they are particularly adaptable for use in systems wherein the data packets are transmitted to a receiver using the Secure Real-Time Transport Protocol (SRTP) as defined in Internet Engineering Task Force (IETF) Request for Comments (RFC) 3711.

Abstract: Plural communication connections are established between an external network and subscriber units by way of a an access network. The subscriber unit connection is supported by plural nodes. When a failure is detected in a node, those subscriber unit connections affected by that failure are identified. A message identifying those subscriber unit connections affected by the failure is sent to one or more other nodes. Affected subscriber unit connections identified in the message are released. Those unaffected connections not included in the message are maintained.
