  • Patent number: 8972582
    Abstract: A method (and corresponding equipment) for use in reauthentication—after a first, full authentication by a first authentication server (23a)—of a communication session involving the exchange of information between a terminal (21) and a server (24), the method including: a step (11) in which the first authentication server (23a) and other authentication servers (23b) are each assigned a respective unique realm name; and a step (13) in which during authentication between the terminal and the first authentication server (23a), the first authentication server (23a) transmits to the terminal (21) a reauthentication identity including the unique realm name assigned to the first authentication server. Then, later, during reauthentication, to make possible that the reauthentication is performed by the same authentication server (23a) as performed the full authentication—i.e. by the first authentication server (23a)—the reauthentication identity is included in a request for reauthentication.

  • Patent number: 8855138
    Abstract: Systems and methodologies are described that facilitate providing relay nodes in wireless networks. In particular, cluster nodes, which can be regular eNBs, can provide wireless network access to the relay nodes over a backhaul link, and the relay nodes can offer access to devices or other relay nodes to expand network coverage and/or provide increased throughput. User equipment (UE) relays can function as UEs according to a cluster node such that UE relays receive network addressing and can tunnel communications through the cluster node using the backhaul link. Cell relays can function as a cell of the cluster node, such that transport layer communications terminate at the cluster node. In this regard, cell relays can define transport layers to use in communicating with the cluster nodes over the backhaul and with other devices over a provided access link.

  • Patent number: 8582480
    Abstract: Policy and charging control (PCC) is a framework within a Third or Fourth Generation (3G/4G) network that allows operators to authorize and enforce policy, Quality of Service (QoS), and charging control over communication sessions by mobile devices. PCC mechanism is used to determine the type QoS based on a request received from a User Equipment (UE) or network. PCC is one important element within System Architecture Evolution (SAE) architecture to allow the network to perform policy and charging control. A mechanism is provided so that PCC can allow packet flow optimization. Thereby, the network can detect Internet Protocol (IP) flows based on operator defined criteria and can perform policy and QoS control.

  • Patent number: 8374631
    Abstract: The invention relates to a mechanism for providing location information regarding mobile terminals, especially regarding WLAN terminals. In order that the known mechanism for locating users of a mobile cellular network could be utilized for locating WLAN terminals, a location service request concerning a WLAN terminal is received and routed by the same network elements that receive and route location service requests concerning users of a mobile cellular network. However, in the case of a WLAN terminal the location service request is diverted to a predetermined network element, where the access point currently serving the WLAN terminal is identified. The location information corresponding to the said access point is then determined, and the location information is returned as the location of the terminal. The location of the serving WLAN access point thus represents the location of the WLAN terminal.

  • Patent number: 8194551
    Abstract: Methods and apparatus for network controlled mobile IP flow movement. An infrastructure node, such as a home agent, signals a mapping between care-of-addresses (CoAs) and flows to be transmitted from a mobile device in uplink communications. The CoA associated with each flow is determined from network, device, and/or flow information. A mobile node or mobile gateway receives the mapping and updates its local policy information. When a selected flow is to be transmitted in an uplink transmission, the local policy information is used to determine the CoA associated with the selected flow. The CoA is then used to determine an access network (or access path) on which the uplink transmission of the selected flow is to occur.

  • Patent number: 8144728
    Abstract: The present invention relates to a method and system for providing access to a cellular network (8), wherein a terminal device (1) is connected to an access device (2) according to access specifications of a broadband access network (12) which is not specifically designed to be used as a part of cellular network (8). The terminal device (1) indicates to the access device (2) that it wishes to be connected to the cellular network (8), and a session or call and a radio bearer is setup between the terminal device (1) and the cellular network (8). To achieve this, a service node (5) provided in the cellular network (8) requests a suitable access bearer from the access network (12) and the access device (2) sets up a corresponding access channel towards the terminal device (1). The terminal device (1) then associates the access channel to the correct radio bearer by using a corresponding identification. Thereby, service functions of the cellular network, e.g.

  • Patent number: 8031644
    Abstract: A method and device of sending and receiving encoded media over a CDMA channel. A plurality of speech frames are output by a media codec, and the plurality of encoded media frames are encapsulated into a packet of a first type. The packet of the first type is encapsulated into a datagram of a second type. The datagram of the second type is encapsulated into a datagram of a third type. The datagram of the third type is divided into a plurality of equal-sized pieces, such that each of the equal-sized pieces fits to a specific CDMA channel frame. Each of the CDMA channel frames is sent over a CDMA air interface, and received at a receive end over the CDMA air interface.

  • Patent number: RE43180
    Abstract: In connection-oriented switching of packet data in known mobile communications systems, resources of the transmission path between the serving node (SGSN) and the radio network subsystem (RNS) and memory resources of the radio network subsystem are reserved unnecessarily due to the burst-like nature of packet data. Thus the transmission network's limited address space and the radio network subsystem's management resources are consumed. The invention concerns such connection management in a mobile communications system, which is suitable for packet-switched data transmission. The method according to the invention is characterized in that the logical connection between the serving node (SGSN) and the radio network subsystem (RNS) is released, so that the logical connection between the serving node (SGSN) and the mobile station (MS) remains, and the released logical connection is reconnected, when relaying of user data starts.

  • Patent number: RE44089
    Abstract: A method for duplex telecommunication connection in radio connections is based on a frame-structured interactive communication and a radio system where the frame-structured interactive communication is performed in the radio connections. A means is provided for improving the use of channel resources in implementation of interactive telecommunication connection by providing an FDD connection with one or more TDD dimensions. A full-duplex frequency band is time-duplexed into two or more sub-bands in which interactive communication takes place substantially independently. Transmissions in different transmission directions in each sub-band occur at different times, but simultaneous transmission can occur in different sub-bands in different transmission directions. The message is received entirely in one transmission direction before it needs to be responded to in another transmission direction in a particular sub-band.
