    Abstract: A system network and method improving handovers, particularly for reducing the amount of inter-cellular transfer information stored in base station controllers or radio network controllers, is disclosed. Instead of storing routing information for every possible inter-cellular handover at each control node, signaling network technology is employed to effectuate communication of all relevant inter-cellular handover information between all of the control nodes, thereby coordinating routing information transference across a distributed system.

    Abstract: User Equipment (UE) receiving non-voice packet switched service in an Evolved Universal Mobile Telecommunications System Terrestial Radio Access Network (eUTRAN) cell undergoes handover to a circuit switched GSM/Edge Radio Access Network (GERAN)/UTRAN cell in response to a requirement for voice service. The voice service is established in the circuit switched domain of a GERAN/UTRAN cell to ensure service continuity regardless of UE mobility that would otherwise not be possible if the voice service was established in the eUTRAN cell. A Gs-like interface between a Mobile Switching Center (MSC) of the CS Core Network and the Mobility Management Entity (MME) of the Evolved Packet Core provides an interface for page requests and location update procedures to be performed.

    Abstract: In the context of a radio communications system that includes a core network coupled to a radio access network (RAN) and a plurality of mobile terminals, a connection may be established between the core network and one of the plurality of mobile terminals through the radio access network. A temporary RAN identifier is associated with the mobile terminal for the established connection. The temporary RAN identifier is used to assist in the transfer of information pertaining to the established connection or to the establishment of that connection through the radio access network. The radio access network includes a first RAN node associated with a first geographical coverage area and a second RAN node associated with a second geographical coverage area. When the mobile terminal moves from the first coverage area to the second coverage area, the connection is re-established through the RAN by way of the first and second RAN nodes using the temporary RAN identifier. The temporary RAN identifier in packets corresponding to the established connection is used to direct those packets to and from the first and second RAN nodes. The first and second RAN nodes analyze packets corresponding to the established connection including the temporary RAN identifier included in each packet. From analysis of the temporary RAN identifier, the first and second RAN nodes determine where packets are to be routed. The temporary RAN identifier is also advantageously employed to facilitate mobile terminal registration and paging operations.

    Abstract: A method for synchronizing measurements in a mobile communication apparatus having a first active radio access means (100) adapted to communicate according to a first radio access technology (RAT) and at least a second passive radio access means (200) adapted to communicate according to a second RAT. A time reference common to the first and the second access means (100) is generated. At least one time schedule is obtained, said schedule indicating at least one time gap wherein the second access means (200) is allowed to be active. The activation time of the schedule is based on the common time reference. An arrangement adapted to generate the common time reference and the time schedule is also disclosed.

    Abstract: Un método para proteger la seguridad de una comu- nicación entre una radio móvil y una red de acceso de ra- dio (RAN) incluyendo establecer una conexión a través de la RAN para soportar una comunicación con la radio móvil, caracterizado por: configurar la conexión con una primera configuración de seguridad; enviar uno o más mensajes por la conexión usando la primera conexión de seguridad, teniendo cada mensaje un número de secuencia de mensaje; determinar la necesidad de reconfigurar la conexión a una segunda configuración de seguridad; poner un número de secuencia de mensaje de activa- ción relacionado con la reconfiguración; y cuando la segunda configuración de seguridad ha de ser activada, enviar un mensaje siguiente con el número de secuencia de mensaje de activación.
