  • Patent number: 8811978
    Abstract: Apparatus and a method for sending measurement report messages from a wireless telecommunications device to a wireless telecommunications network are disclosed. The method comprises at the wireless telecommunications device: generating a measurement report in respect of a first event; transmitting a first message including the measurement report in respect of the first event to the network; generating a subsequent measurement report for another event; determining whether conditions for the first event are still satisfied and, if so, including in a subsequent message the measurement report for the first event as well as the measurement report for the other event; and transmitting the subsequent message to the network.

  • Publication number: 20140051415
    Abstract: Examples of reducing data transfer latency caused by state transitions in mobile networks are disclosed. A first disclosed example method comprises, while operating in a first state having fewer available radio resources than would be available in a second state, setting a traffic volume indicator if a wireless device determines that a radio link control (RLC) buffer occupancy is larger than a traffic volume measurement threshold, and sending the traffic volume indicator to a network in a transmitted message other than a CELL UPDATE message having uplink data transmission as an update cause. A second disclosed example method comprises, while operating in a first state, receiving a message that is to cause a wireless device to transition to a second state having fewer available radio resources than are available in the first state, and rejecting the message if the wireless device has pending uplink data to send to a network.

  • Publication number: 20140040547
    Abstract: A technique is disclosed for non-disruptive migration of data between storage on hosts that do not share storage with each other. Aggregate relocation is enabled to operate between the hosts in the absence of shared storage connectivity. The technique includes mirroring an aggregate from storage of a first host to storage of a second host by using a sub-RAID level proxy in each of the first and second hosts to proxy data communications between the hosts. The proxy is used in lieu of the mirroring application in the first host having direct access to the storage devices of the second host. The technique further includes relocating the aggregate from the first host to the second host.

  • Publication number: 20130232181
    Abstract: A technique is disclosed for providing high availability (HA) capability with a plurality of storage servers, which may be virtual storage servers (VSSs), in a shared-nothing storage environment. The technique uses a proxy mechanism to route requests originating at one storage server to an HA partner storage server, where the proxy is implemented inside a VSS logically below the RAID layer. The technique also involves distributing non-shared storage devices “owned” by a storage server so that existing storage device-based heartbeat and fencing mechanisms can function unmodified for HA VSSs in shared-nothing environments. For example, a third, external host can be used to provide and export its non-shared storage to first and second storage servers, where the first and second storage servers do not own the non-shared storage on their local physical host machine.

  • Publication number: 20130189992
    Abstract: A method at a user equipment for establishing a circuit switched call, the user equipment being in a Cell Forward Access CHannel (CELL_FACH) state, a Cell Paging CHannel (CELL_PCH) state or a UTRAN Registration Area Paging CHannel (URA_PCH) state, the method receiving an indication that a circuit switched call is pending; sending to a network element a message to facilitate the user equipment to transition to a Cell Dedicated CHannel (CELL_DCH) state, the message being one of a cell update message having a traffic volume indicator information element indicating that pending uplink data exceeds a threshold or an RRCConnectionRequest message; and establishing the circuit switched call.

  • Publication number: 20130003523
    Abstract: A system and method for addressing RLC unrecoverable errors experienced by User Equipment (UE) in a wireless network help the network to resolve the errors without shifting the UE into an Idle mode and dropping voice calls. A measurement event provides the buffer occupancy and identifies the affected radio bearer to the network. If the state of the bearer is not changed, the UE provides a Signaling Connection Release Indication message or a Radio Bearer Release Indication message to the network, the latter message identifying the radio bearer to be released without taking down the entire signaling connection for the domain.
