摘要： A radio frequency communications system (100) includes wireless terminals (102) and base sites (104). The wireless terminals communicate with the base sites over a radio frequency channel (106). The base sites are interconnected to each other and other network elements via a packet network. The communication system has a radio frequency channel (400) with time slots (406, 408) for transmission of both delay-sensitive data, such as streaming audio and video, and non-delay-sensitive data. A method and apparatus are provided for determining whether a time slot in the radio frequency channel is to be allocated to delay-sensitive data or non-delay-sensitive data (704, 706, 708). Each packet of data transmitted over the wireless channel has a type of service field (900). The type of service field has a precedence or priority value (902) and a service type (904). The priority values are used to determine which packet should be transmitted across the radio frequency channel next and the service type determines the transmission protocol.

摘要： A method for synchronizing audio reproduction in collocated end devices is presented. Each of the devices auto-correlates using noise to determine a threshold prior to the antenna receiving an audio signal. When the devices receive a common audio signal, they provide audio outputs. Each device cross-correlates its audio output with the audio outputs of the other devices. The timing of the audio output of each device is then adjusted such that the audio outputs of all of the devices align temporally with the lagging or leading device.

摘要： Some embodiments are directed to methods and apparatuses for enabling voice discussions about a same data content being independently and simultaneously accessed on at least two devices. A server detects when a first device of the at least two devices accesses the data content. The server identifies and reserves an available voice communication group resource. Responsive to detecting that the at least two devices are independently and simultaneously accessing the data content, the server identifies and reserves an available voice communication group resource, and sends a voice group identifier for a reserved voice communication group resource to the at least two devices to allow access to the reserved voice communication group resource.

摘要： Methods for enabling floor control are performed in an endpoint terminal (140, 142, 146) and a session controller (106). The session controller: receives (410) a message requesting a session that includes an SDP packet with a requested floor control profile having a requested set of floor control parameters or a requested list of potential floor owners; accepts (410) the session; determines (420) a final floor control profile having a final set of floor control parameters and a final list of potential floor owners; and communicates at least a portion of the floor control profile within a system (100). The endpoint terminal: communicates a message requesting a session that includes an SDP packet with a requested floor control profile; and receives a message having an SDP packet with a final floor control parameter. The final floor control profile may be the same as or different from the requested floor control profile.

摘要： A radio frequency communications system (100) includes wireless terminals (102) and base sites (104). The wireless terminals communicate with the base sites over a radio frequency channel (106). The base sites are interconnected to each other and other network elements via a packet network. A method and apparatus determine for a particular delay-sensitive application on the wireless terminal, for example, an audio or video transmission, the requirements for bandwidth for transmission over the radio frequency channel (500, 502). After the requirements on the radio frequency channel are determined, the necessary channel bandwidth, if available, is reserved or allocated to guarantee performance to the application (510). The reserved bandwidth is utilized by selectively granting access to the radio frequency channel on the basis of the bandwidth allocated to the device.

摘要： A method and system for establishing floor control in a communication session enables remote control of devices in a network and provides a status update concerning floor ownership. The method includes processing at a floor controller a floor request message received from a first endpoint, where the floor request message requests that floor ownership be provided to a second endpoint (step 305). A floor control announcement message is then transmitted from the floor controller to at least both the first endpoint and the second endpoint, where the floor control announcement message indicates that the second endpoint has floor ownership (step 315).

摘要： A method for providing a mobile device in a packet data network access to a channelized network is disclosed. At a gateway between the two networks, a first channelized network message that is encapsulated in a first IP data packet from the packet data network is received. The first channelized network message is retrieved and reformatted for sending over the channelized network. The gateway then receives a second channelized network message from the channelized network. An identifier of a mobile device associated with the second channelized network message is retrieved and an IP address for the identified mobile device is determined. Then, the gateway encapsulates the second channelized network message into a second IP data packet and sends the encapsulated second channelized network message to the identified mobile device in the packet data network.

摘要： Communication units are provided access to a communication system (100) in the following manner. A base station (202) receives, from a requesting communication unit, a request, via a shared inbound communication resource (209), for an available message path (207). When a dual-mode outbound communication resource is operating in a control mode (205), the message path (207), having a first inbound communication resource (204) and the dual-mode outbound communication resource operating in a partial control mode (206), is assigned to the requesting communication unit. Thus, the shared inbound communication resource is consistently available, providing access to the communication system.
