Abstract:
A method and apparatus for providing an efficient dormant mode for push-to-talk communication devices in a group communication network provides for determining whether the communication device has been inactive for a predetermined first time period and, if so, causing the communication device to enter a control-hold mode, wherein the communication device maintains its dedicated traffic channel. The method further includes the steps of determining whether the communication device has been in the control-hold mode for a predetermined second time period and, if so, causing the communication device to enter a dormant mode, wherein the communication device releases its dedicated traffic channel. The method and apparatus further provides for causing the communication device to cache its service configuration state before entering the dormant mode.
Abstract:
A method and apparatus for automatically reconfiguring a wireless communication network (200) provides for determining availability of a resource based on information received at a first node (208) from a second node (204, 206, 208) operating in the network. The first node is capable of functioning as a base station controller, mobile switching center, and/or a base transceiver station. Based on the determined availability of the resource based on the received information, the first node is reconfigured by disabling one or more of the capabilities of the first node.
Abstract:
A wireless dispatch service in a full duplex wireless telephone system includes forward and reverse link pairs assigned to each voice communication device in a dispatch system. Depending on whether a device is talking or listening, one of the links for that device can be idled to conserve system energy, thereby approximating a half duplex system.
Abstract:
A push-to-talk communication device to participate in a group communication net (100) is claimed. The group communication net (100) comprises a controller (104) to manage the group communication net (100) and interface with the push-to-talk communication devices (108, 112 and 116). A processor converts information signals into packet data suitable for transmission over a distributed network. The processor may also have identification information, and updates its identification information when its current identification information has or is about to change. The processor then transmits its new identification information to the controller (104). The push-to-talk devices (108, 112 and 116) also comprise a transmitter to transmit packet data through a first channel to the controller. A receiver receives packet data through a second channel from the controller. The push-to-talk devices (108, 112 and 116) also comprise a user activated mechanism to activate the transmitter when a user of the communication device wishes to transmit packet data to the controller.
Abstract:
In an embodiment, a server registers a client application installed on a user equipment (UE), and evaluates one or more paging cycle criteria for the registered client application. The server determines to establish a target paging cycle used for downlink paging of the UE by a network component (e.g., an access network component or a core network component) of a serving network based on the evaluation, and the server transmits, to the network component, a request for the network component to transition the given UE to the target paging cycle based on the determination. The network component receives the request and assigns the target paging cycle to the UE as requested.
Abstract:
The disclosure is related to dynamically applying quality of service (QoS) to a call. An aspect determines a packet transmission state of a subscriber on the call, determines whether or not the QoS is allocated to the subscriber, and allocates the QoS to the subscriber based on the QoS not being allocated to the subscriber and the packet transmission state indicating that the subscriber is sending packets. Dynamic QoS allocation to a push-to-talk PTT over cellular PoC.
Abstract:
In an embodiment, a network device obtains a plurality of data packets that are each associated with one of a plurality of different streams, wherein each of the plurality of obtained data packets includes a header portion with stream-specific routing information. The network device strips the stream-specific routing information from the plurality of obtained data packets to produce a plurality of stream-specific payload portions, which are merged into a shared payload portion of a stream-multiplexed data packet that includes common routing information for the plurality of streams in a common header portion. The network device transmits the stream-multiplexed packet to a target device, and the target device determines whether any of the plurality of different streams are relevant to the target UE based on stream-mapping information contained in the stream-multiplexed packet, and selectively decodes and processes the stream-specific payload portions corresponding based on the determination.
Abstract:
In an embodiment, an application server determines to transmit a first data stream in a first multicasting area, a second data stream in a second multicasting area and both data streams in a third multicasting area that overlaps with the second multicasting area (e.g., at a border region between the first and second multicasting areas). The application server sends the first data stream to a multicast network management node for transmission in the first and third multicasting areas. The application server sends the first and second data streams to a multiplex stream multiplexer that multiplexes the two data streams into a single higher-rate multiplexed multicast stream with packets that include payloads data for both the first and second data streams. The multiplexed multicast stream is delivered to the third multicasting area for transmission to at least one target UE.
Abstract:
The disclosure is directed to prioritizing call announce response in a broadcast / multicast communication system. An embodiment establishes a first priority (810; 910) for response based on assigning each user equipment (UE) (120; 520; 522; 1000) a first random delay for response to a first call announce (740), responds to the first call announce using the first random delay, and determines a second priority (820; 920; 930; 940) for response to a subsequent call announce based on an elapsed time that each UE is present in a multicast area.
Abstract:
Embodiments are directed to managing a prepaid server-arbitrated group communication session within a wireless communications system. A server receives, from a session originator, a request to setup a prepaid group communication session with at least one session target, the prepaid group communication session requiring each session participant to have an available prepaid account balance above a threshold level. The server sends a query to an online charging system to determine whether at least the session originator has a prepaid account with an available balance at least equal to the threshold level. The server initiates setup of the requested prepaid group communication session without waiting to receive a response to the query, thereby reducing latency associated with set-up of the prepaid group communication session.
