Abstract: Disclosed is a method and system to help manage latency and reduce unnecessary signaling in setup of fallback communications, such as circuit switched fallback calls for instance, by taking into account the load in various fallback coverage areas. When the load of a fallback coverage area is threshold high, signaling may pass to a serving network to cause that fallback coverage area to be filtered out of a list of fallback coverage areas that a base station of the serving network would provide to a served device, so as to help avoid having the device scan for coverage of that fallback coverage area.

Abstract: The present invention relates to a physical layer signalling in a digital broadcast network. In particular, for a digital broadcast network supporting a configuration with a plurality of physical layer pipes, a type indicator is signalled on physical layer for a pipe, the type indicator indicates the format of the input stream which may specify a transport stream, a generic stream or an IP stream. In addition, per physical layer pipe application of header and/or content compression to the user packet headers of the input stream is signalled. Another physical layer parameters are advantageously provided or extended in order to increase the flexibility and efficiency of the layer 1 signalling.

Abstract: Techniques for energy efficient notification services are described. A telecommunications device may acquire multimedia/notification service data from various upstream units, e.g., one or more multimedia/notification service servers, at least one push notification service server and/or a storage system. The telecommunications device may select a communication channel between the telecommunications device and the various upstream units for acquiring multimedia/notification service data. The telecommunications device may select the communications channel based at least in part on efficiencies, e.g., it may select the most energy efficient communications channel. The telecommunications device may, in some instances, acquire the multimedia/notification service data as pushes from one or more upstream units (e.g., a push notification service server), and may, in some instances, acquire the multimedia/notification service data as pulls from one or more upstream units (e.g.

Abstract: Provided is an initiator apparatus that, when issuing access requests for remote access via wireless communication to a storage section that processes only one access request at a time, can easily detect timeouts with one timer irrespective of the number of access requests issued via wireless communication. In this apparatus, an access-request processor (102) sends one or more access requests to a target apparatus (110) provided with a storage section that processes only one access request at a time and receives access acknowledgments for the access requests from the target apparatus (110). Until all the access requests are completed, a timeout detector (103) resets the timer operation and starts it again each time an access request is sent or an access acknowledgment is received, and detects a timeout when the timer operation exceeds a timeout period.

Abstract: A method in a communication terminal includes receiving a signal that carries a data channel and at least a control-channel message, which has a first part that is masked with a terminal-specific code. A second part of the control-channel message that is not masked with the terminal-specific code is decoded to produce a decoded second part. The validity of decoded second part is checked. In response to deciding that the decoded second part is valid, a noise level for the data channel is estimated based on the decoded second part.

A configurable clock tree includes a delay matrix that may be configured such that each the timing of clocks for each of a plurality of data lanes can be optimized for minimum skew. Selections between different versions of a base clock signal and different paths available to the selected version may provide a root clock used for transmitting data on a communications link. The versions of the one or more clock signals may include three versions of a first clock signal. Each version of the first clock signal may be subject to a different delay with respect to the clock signal.

Abstract: Methods for transporting a media call between an IMS server and a User Equipment (UE) and of handing over the media call between a cellular network and a WLAN are provided. In an embodiment, the media call data and signaling are split such that the data is transported over the WLAN and the signaling is transported over the cellular network. In another embodiment, handover latency is reduced by using a dual registration process that registers the UE with an IMS server using both a WLAN-based contact and a cellular network-based contact. The media call can then be carried over the WLAN and/or the cellular network and can be handed over seamlessly from one to the other within minimal signaling.

The apparatus further comprises an arbitration circuit communicatively coupled between the half-duplex translation layer circuit and the full-duplex link layer circuit, the arbitration circuit to control data flow between the half-duplex translation layer circuit and the full-duplex link layer circuit. The arbitration circuit provides interface and signaling rules for transmitting packets from the half-duplex translation layer circuit to the full-duplex link layer circuit, receiving packets via the full-duplex link layer circuit at the half-duplex translation layer circuit, and resolving conflict arising due to bidirectional data flow at the arbitration logic.

Abstract: A method is disclosed for increasing the communication capacity of a shared ad-hoc wireless channel by using multiuser detection (MUD) to distinguish overlapping information transmitted simultaneously by a plurality of nodes. The transmitting nodes simultaneously provide parameter-estimating signals over separate, unshared, low-rate parameter channels generated using orthogonal frequencies, spread spectrum technology, or time multiplexing. Receiving nodes use these separate, non-overlapping parameter-estimating signals to estimate MUD-required signal parameters such as amplitude, phase, and frequency offset, thereby enabling use of lower complexity MUD receivers, because the parameters are not estimated in the presence of other interference. Node ID, spreading code type, and/or other information can also be transmitted over the parameter channels. Limiting the number of parameter channels can limit the maximum number of transmitting nodes.

Abstract: A method enabling symmetric routing between a first host within a first AS and a second host within a second AS is disclosed. The method includes detecting that a first routing message was received at an edge router of the first AS from an edge router of the second AS. The first message identifies the second host as a source and the first host as a destination of a forward route. The method further includes determining that the first message further comprises an indication to implement symmetric routing between the first and second hosts and generating a second routing message for propagating to router(s) within the first AS. The second message identifies the first host as a source and the second host as a destination of a return route, and indicates that data is to be sent via the edge router of the first AS that received the first message.
