摘要： A method and apparatus are provided for a gateway which interconnects public safety wireless networks and commercial wireless networks that support push-to-talk group calls. The gateway translates Real Time Protocol (RTP), Session Invitation Protocol (SIP), and Talk Burst Control Protocol (TBCP)/Real Time Control Protocol (RTCP) messages received from the commercial wireless network and RTP and SIP messages received from the public safety wireless network into a format of the receiving network. The gateway has a call control component operable to set up and tear down RTP connections between the networks, a push-to-talk control component operable to arbitrate calls between wireless communications handsets of both networks, and a transmission control component operable to transfer media packets between the networks. The gateway reduces the number of call set ups required when a caller wants to speak because connections may remain active until the talk group participants leave the push-to-talk group call.

摘要： An exemplary gateway apparatus provides push-to-talk (PTT) communications between users in one network with users in another network where the networks utilize different communication protocols. It includes two protocol modules that interface with the two networks, respectively. The protocol modules are capable of receiving and transmitting messages compatible with the communication protocols used by the associated networks. An interoperability module, connected between the two modules, converts PTT control messages received from one of the networks into PTT control messages compatible with and transmitted to the other network. The PTT control messages received from the one network have a protocol that differs from the protocol of the PTT control messages transmitted to the other network.

摘要： A method and apparatus are provided for a set of procedures that a push-to-talk (PTT) server can use to control multiple simultaneous media streams within a talk group. The present invention provides floor control messages and protocols for identifying, transmitting, and distributing the simultaneous media streams. The invention may be used with any real-time protocol (RTP) payload format as long as the encoding allows a receiver of the packets means to distinguish between the transmitting clients. Although the present invention provides server-based control of multiple transmissions, end-point-based transmission control procedures are supported.

摘要： Various embodiments provide a method and apparatus of providing a non-overlapping ring-mesh network topology which reduces costs (e.g., the number of network links) while providing resiliency to failure and meeting QoS requirements (e.g., network delay attributed to traversing the network architecture). In particular, a set of target nodes belonging to a cluster are connected through N rings. Each node is member of all N rings and no link between nodes in a ring is duplicated in another ring.

摘要： An example method includes receiving at a scheduling server status information concerning at least one transmit queue for a plurality of optical pass-through switches (OptSws). A schedule for transmissions to take place is determined based on the status information for the OptSws. A control message is forwarded to the plurality of OptSws in order that the schedule may be implemented. In an embodiment, a schedule is determined for a wavelength available to transmit a transmission by removing unsupportable transmissions from a candidate transmission list, determining a first transmission that is the one of the transmissions of the candidate transmission list which most preferably satisfies a given parameter, updating a usage list to reflect determination of the first transmission; and replacing the candidate transmission list with the residue set of the first transmission. The usage list reflects transmissions determined by the scheduler.

摘要： For voice traffic over-the-air in LTE, persistent schedule (PS) or semi-persistent (SPS) scheduling would be the preferred method as they minimize signaling messages. In PS or SPS, resources are pre-allocated to the UE 402 at regular intervals (e.g., every 20 milliseconds). At each time slot, the UE will generally transmit an IMBE frames which are encoded in ISSI packet. In ISSI, other data streams are multiplexed with the IMBE frame and thus the packet size varies depending on its position within a super-frame. For PS or SPS, eNodeB must allocated sufficient resources to support the largest packet that. Therefore, there is spare capacity when the packet is not of the largest size. The exemplary embodiments specify ways to use spare capacity to transfer data.
摘要翻译：对于LTE中的语音流量，持续调度（PS）或半永久（SPS）调度将是最小化信令消息的首选方法。在PS或SPS中，资源以规则的间隔（例如，每20毫秒）预先分配给UE 402。在每个时隙，UE将通常发送以ISSI分组编码的IMBE帧。在ISSI中，其他数据流与IMBE帧复用，因此分组大小根据其在超帧内的位置而变化。对于PS或SPS，eNodeB必须分配足够的资源来支持最大的数据包。因此，当数据包不是最大的大小时，有空余的容量。示例性实施例指定使用备用容量来传送数据的方式。

摘要： A method and system for group call control in a broadband wireless network. A group call (push-to-talk) server initiates and regulates group call communication sessions. A wireless base station communicates with one or more group call participants. When a request to participate in a group call is received, it is examined to see if it contains a group call ID or other group call indicator. If not, regular call resources are allocated, if available. If so, it is determined whether another group member is attached to the base station. Group call resources are then reserved, if available, based on this determination. The resources allocated for the group call may also depend on whether the system supports multicast on the downlink to group members, or whether losing audio is supported. In some embodiments, network resources may be reallocated to support the group call.
