  • Patent number: 9723523
    Abstract: Methods and systems for managing Multimedia Broadcast Multicast Service (MBMS) service continuity include, with a source node in a communication system, providing an MBMS, processing an event that indicates that a User Equipment (UE) being serviced by the source node is to be transferred to one of a number of candidate nodes, receiving a congestion bit from each of the candidate nodes, and providing data to the UE that causes the UE to be serviced by a target node selected from the candidate nodes based at least in part on values of the congestion bits from each of the candidate nodes.

  • Patent number: 8750181
    Abstract: Systems, apparatuses, and computer implemented methods may be directed to identifying that a UE is near a cell edge of the source base station, the UE receiving or requesting a multimedia broadcast multicast service (MBMS). A target base station can be identified based, at least in part, on the MBMS received at or requested by the UE. The target base station can be provided to the UE, for example, by providing an indication to the UE of a target base station from which to receive services. The target base station may be acquired through a handover procedure (RRC connected), or through a cell selection procedure (RRC idle). The target base station can be identified based on a multimedia broadcast single frequency network area identifier (MBSFN AreaID) for a synchronized MBMS continuity across network cells or by a temporary multicast group identity (TMGI) for asynchronous MBMS continuity across network cells.

  • Patent number: 7991397
    Abstract: Provided are systems and methods for generating a blacklist for femtocells. According to an embodiment of the application, a mobile device generates and maintains a femtocell blacklist including an identification of at least one femtocell to be avoided by the mobile device. Upon detecting a femtocell, the mobile device determines whether the femtocell is identified in the femtocell blacklist. If the femtocell is identified in the femtocell blacklist, then the mobile device avoids any attempt to use the femtocell. This might allow the mobile device to conserve battery power and reduce wireless communication resources. Since the femtocell blacklist is generated and maintained by the mobile device, the network infrastructure does not need to generate and manage the femtocell blacklist. Also, there is no need for the mobile device to download a femtocell blacklist or updates thereof from the network infrastructure.

  • Patent number: 7725600
    Abstract: This invention provides an improved address management scheme in a mobile router (MR) that connects a mobile network into the Internet via an access network. The MR performs neighbor advertisement on behalf of mobile network nodes (MNNs) within the mobile network so that packets directed towards the MNNs are routed correctly to the MR, and then to the corresponding MNN, while maintaining standard address management procedures, such as IPv6 address management procedures, in the access network and in the mobile network.

  • Patent number: 7668145
    Abstract: The invention proposes a method for controlling a connection between a first network node and a second network node, wherein the connection is controlled by a packet filtering function filtering packets such that a packet is discarded in case a source address and/or a destination address do not comply with a filtering rule, wherein the packet filtering function is configured at a connection set up, and at least one of the first or second network node is adapted to change its address, the method comprising the steps of informing, the packet filtering function about the new address of the network node having changed its address, and updating the packet filter of the packet filtering function by using the new address of the network node having changed its address. The invention also proposes a corresponding network system comprising at least a network node and a packet filtering network element. Furthermore, the invention proposes a corresponding packet filtering network device.

  • Patent number: 7599345
    Abstract: A method, network elements, a terminal, and a system of triggering events in a protocol layer stack of a communication system comprising at least one terminal and a network infrastructure including at least a first network element and a second network element, the method comprising the steps of detecting a terminal-related event of a lower protocol layer at the first network element; initiating a network-related event of a higher protocol layer to be rendered effective at the terminal, wherein the step of initiating further comprises a step of determining a necessity for the higher layer event on the basis of the detected lower layer event, and the step of initiating is effected in case the step of determining yields a necessity for the higher layer event to be triggered.

  • Patent number: 7307955
    Abstract: A “loose ACK” method by which a radio access network of a cellular network monitors wireless transmission of packets according to a layered protocol including a radio layer (near the physical layer) and an upper layer, the method including: a step (23) of slow release—in what is called normal buffer management—in which the upper layer removes from a buffer maintained by the upper layer the oldest packet in the buffer when the buffer is full and a new packet arrives, and does so independently of whether the packet being removed has been acknowledged by the radio layer of the terminal; and a step (24) of local acknowledgement in which the radio layer sends an acknowledgement to the upper layer on the occurrence of a predetermined event. The local acknowledgement can trigger either special mode buffer management or release of the buffer to a target (entity or layer).
