  • Publication number: 20180255485
    Abstract: The present disclosure relates to a method in a mobile station for base station change from a source base station to a target base station in a cellular radio network. The base station transfers packet switched communications between the mobile station and the network, and the method comprises receiving a handover command message from the source base station at the mobile station. The method further comprises transmitting in a target cell a message to the network providing a downlink sequence number status for a packet flow subject to lossless packet switched handover implicitly acknowledging downlink packets received by the mobile station.

  • Patent number: 9998958
    Abstract: A mobile station (MS) and method for base station handover from a source cell of a source base station to a target cell of a target base station in a packet-switched cellular radio network. While the MS is still in the source cell, the MS receives from the network, a handover command message and information regarding a next expected uplink packet for a packet flow subject to lossless packet-switched handover. Upon arrival of the MS in the target cell, the MS transmits an uplink sequence number status message to the target base station providing a downlink sequence number status for the packet flow, and starts uplink data transmission to the target base station beginning with the next expected uplink packet.

  • Patent number: 9629019
    Abstract: A method and apparatus for interrupting the lower priority packet transmission/reception for higher priority packet transmission/reception within the context of a common RLC entity is provided herein. The transmission/reception of lower priority data blocks containing data segments of a first higher layer packet is interrupted to transmit/receive higher priority data blocks containing data segments of a second higher layer packet. After the transmission/reception of a final segment of the second higher layer packet, the transmission/reception of the first higher layer packet is resumed. In some embodiments, a final segment of the second higher layer packet is encapsulated in a final higher priority data block with a remaining data segment of the first higher layer packet. The final higher priority data block further includes a transition indicator to indicate a transition from the second higher layer packet back to the first higher layer packet.

  • Patent number: 9532372
    Abstract: In one aspect, the invention provides apparatuses and methods for wirelessly transmitting application data utilizing priority information for each radio link control (RLC) data block transmitted. Advantageously, the application data with a relatively high transmission priority is not substantially delayed by the transmission of application data with substantially lower transmission priorities.

  • Patent number: 9445215
    Abstract: A machine type device for deployment in a wireless network includes a processing circuit operable to generate an application layer message and a request including information identifying the machine type device as capable of using a particular protocol stack. After radio resources are setup between the machine type device and the base station controller, the processing circuit is further operable to transmit the application layer message and a local wireless network alias to a base station controller, the local wireless network alias indicating the machine type device is capable of using the particular protocol stack.

  • Patent number: 9357452
    Abstract: A telecommunications node (e.g., base station subsystem) and method are described herein that broadcasts a set of system information messages (e.g., SI2quater messages or pairs of SI2ter messages and SI2quater messages) for use by a legacy mobile station which enhances the overall probability (over time) that the legacy mobile station (non-supporting mobile station) in a network sharing scenario will find frequency, cell information or a combination of both within the broadcasted system information messages to be used for the legacy mobile station's cell reselection process to provide continuity with the legacy mobile station's registered PLMN (i.e. the Common PLMN of a shared radio access network). In addition, the telecommunications node (e.g., base station subsystem) and method can also broadcast a different type of system information message for used by a supporting mobile station.

  • Patent number: 9277460
    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.

  • Patent number: 9264975
    Abstract: When a wireless terminal attaches to the network, the wireless terminal is assigned a temporary identifier. Different sets of access restrictions are associated with different blocks of temporary identifiers. When a message and a corresponding temporary identifier is received by the network from a requesting wireless terminal, an access controller identifies the block to which the assigned temporary identifier belongs and determines the access restrictions associated with that block.

  • Patent number: 9198011
    Abstract: The transmission of a warning message to a mobile terminal in a mobile communication network is triggered by an emergency event. The mobile terminal is first made aware of the need to receive a warning message by reception of an emergency event notification. The warning message is divided into a plurality of message segments. Each segment is transmitted in a separate paging message over a paging channel to mobile terminals in an idle mode. Information is added to each message segment to enable the mobile terminal to discriminate between segments belonging to different warning messages.

  • Patent number: 9137709
    Abstract: User Equipment (UE) receiving non-voice packet switched services 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 voice service page. An eNodeB of the active eUTRAN cell uses a measurement report history for the UE to select an available circuit switched cell for handover. 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.

  • Patent number: 9015319
    Abstract: A layered approach to access control is used where each access control layer implements a set of access control rules. The access control rules in each layer are applied in order beginning with the first access control layer. To gain access to the network, the access attempt must not be barred by any access control layer.

  • Patent number: 8995467
    Abstract: A system and method for providing an indication of a priority level of a non access stratum (NAS) message. In one aspect, a wireless communication device transmits a NAS signaling message together with a Packet Flow Identifier (PFI) information element that includes information indicating a priority level of the NAS signaling message. If the NAS signaling message has a low priority, the wireless communication device may receive a response message indicating that the ongoing NAS signaling message scenario can be performed less frequently in the future, thereby mitigating network congestion and radio interference.

  • Patent number: 8995336
    Abstract: An MTC device activates an MTC service by first performing an MTC device attachment procedure to attach to a mobile communication network. After the MTC device is attached to the mobile communication network, the MTC device activates a packet data protocol context for the MTC device with the mobile communication network. After the packet data protocol context is activated, the MTC device activates an MTC service with an MTC server.
