US07983232B2 Wireless LANs and neighborhood capture
Overlapped wireless LAN cells in a medium have an equal chance at establishing a session on the medium. A first member station in the first cell transmits a timing packet containing a timestamp value, which is received at a second member station in the second cell. This synchronizes member stations in the first and second cells to interrupt transmissions at a global channel release instant corresponding to the timestamp value. The member stations in the first and second cells then have the opportunity to contend for access to the medium following the global channel release instant, using a slotted CSMA/CA access method. Each of the member stations in the first and second cells has a superframe clock that is synchronized based on the timestamp value, thereby establishing a periodic global channel release instant during each of a plurality of periodic superframes. The member stations can then periodically interrupt transmissions at the periodic global channel release instant to contend for the medium. The periodic global channel release instant occurs at intervals that are sufficiently close to meet delay and jitter restrictions for time-critical voice and video applications.
US07983227B2 Communication terminal apparatus, communication connection apparatus, and communication method using them
In the conventional network using the PPP stipulated by RFC1661, the LCP phase to establish an LCP link, the authentication phase, and the NCP phase such as address assignment processing of the NCP are sequentially conducted each time the line connection is performed, and hence the connection takes a certain period of time. Particular, in the case of the mobile communication, there is often performed operation in which connection and disconnection are frequently conducted in a short period of time, and hence when the operation up to the connection takes a long period of time, the usability is deteriorated. Therefore, a need exists for a configuration of an apparatus and a communication method to reduce the connection time. In the configuration, control information such as authentication policy and protocols for use beforehand determined in the communication system are set to each apparatus to conduct communication such that the respective processing phases of the LCP, authentication, and NCP processing phases are executed in parallel according to the values set as above.

US07983221B2 Method and apparatus for radio link failure recovery in a wireless communications network
In a method for radio link failure (RLF) recovery in a wireless communications network, a timer T sets a predetermined time period from a command to a mobile terminal UE to hand over to a new eNB. Resources are reserved at a target eNB 2. If the time period expires without the UE attaching to the target eNB 2, the source eNB requests other candidate eNBs 3 and 4 to reserve resources. Once the UE associates with the target eNB 2, the resources reserved at candidate eNBs 3 and 4 are released. If the UE associates with the target eNB 2 prior to expiry of the time period T, resources are not unnecessarily reserved at the candidate eNBs 3 and 4. If the UE associates with one of the candidate eNB 3 instead of the target eNB 2, resources have already been reserved, enabling RLF recovery to be implemented without the UE going via LTE_IDLE, in an LTE arrangement.
