摘要： For a push-to-talk function in a mobile communication system (30), an indication is received (35) by a user (50) that the talking floor is available. Next, an uplink temporary block flow is established (36). Prior to release of the uplink temporary block flow by the mobile communication system, a refresh message is sent (39) to hold the uplink temporary block flow. Downlink temporary block flows may also be refreshed by this method, or by the mobile communication system. Then the requesting user may enable the push-to-talk function. These techniques can improve talker arbitration and call setup delays for push-to-talk.

摘要： A method for providing dynamic group call among a group of users both wireless (10-30) and wireline (40) places the selectability of the call in the hands of an originating user (10). An originating user (10) may make a fixed number of entries (80). The originating user (10) can create a dynamic group call, add a group call list for later execution, add a member to the group call list, or create a dynamic group call list and immediately execute a group call (92). The method for dynamic group call also provides for selecting a time to live for each group call entry (81) in database (60). This parameter time to live is directly selectable by the originating user (167) or the server. In addition, any member to a previous or existing group call may rejoin or reestablish the dynamic group call (220).

摘要： The present invention encompasses a method of facilitating a talkgroup call throughout a communication network (100). A typical multi-system network (100) includes a plurality of communication units (122), a plurality of communication location areas (117-119), and a plurality of system controllers (110, 116). A communication unit (122) sends a request for a talkgroup call involving members of a first talkgroup to a system controller (116). The system controller (116), after receiving the talkgroup call request, determines which other communication systems in the multi-system network (100) contain members of the requested talkgroup. The system controller (116) sends a talkgroup call command to all communication systems that presently contain members of the first talkgroup, thereby facilitating the talkgroup call throughout the communications network.

摘要： Processing of dispatch calls in a multi-site communication system begins when a source communication unit initiates a request for a dispatch call. The request is routed to a controller which assigns a controlled device to support the request. In addition, the controller identifies the destination communication units, which site each of the destination units are in, and what controlled devices are needed to support the dispatch call. Having identified the controlled devices, the controller assigns all of the controlled devices needed the same temporary network address. With all the controlled devices having the same temporary network address, the controlled device assigned to support the request can transmit the messages generated by the source communication unit to other controlled devices using the temporary network address. Thus only one representation of a message produced by the source communication unit is transmitted from the assigned controlled device.
摘要翻译： 当源通信单元启动对调度呼叫的请求时，多站点通信系统中的调度呼叫的处理开始。 请求被路由到控制器，该控制器分配受控设备来支持请求。 此外，控制器识别目的地通信单元，每个目的地单元所在的站点以及支持调度呼叫所需的受控设备。 在识别出受控设备后，控制器分配所有受控设备所需的相同临时网络地址。 在所有受控设备具有相同的临时网络地址的情况下，分配用于支持请求的受控设备可以使用临时网络地址将由源通信单元生成的消息发送到其他受控设备。 因此，从分配的受控设备仅发送由源通信单元产生的消息的一个表示。

摘要： A wireless communication system 200 comprises a connectionless packet network 201 coupled to a plurality of sites 203–208. Upon a first communication unit (213) initiating a call request for a 2-party call with a second communication unit (215), a call server 235 identifies respective multicast IP addresses (MC1, MC2) associated with the source and target. If the first communication unit 213, or its associated site (205) desires to send payload to the second communication unit 215, it addresses the payload to the multicast IP address (MC2) of the second communication unit, and the second communication unit 215, or its associated site 206 joins the multicast address MC2 to receive the payload. Conversely, if the second communication unit 215, or its associated site (206) desires to send payload to the first communication unit 213, it addresses the payload to the multicast IP address (MC1) of the first communication unit, and the first communication unit 213, or its associated site 205 joins the multicast address MC1 to receive the payload.

摘要： A wireless communication system 200 comprises a connectionless packet network 201 coupled to a plurality of sites 203-208 that are in wireless communication with a plurality of subscriber units 210-217 logically arranged into a plurality of talk groups having corresponding talk group identifications. In one embodiment, each site maintains mappings 220-225 of at least one multicast address to at least one talk group identification. In another embodiment, individual subscriber units maintain such mappings 320. When a subscriber unit affiliates with a given site and talk group (501, 601), the site identifies a multicast address corresponding to the talk group. Based on the multicast address, the site can participate in traffic targeted for the multicast address and, consequently, for the talk group. In this manner, mobility Processing is decentralized, system calability is improved and call setup delays are minimized.

摘要： A determination is made whether a service provider (28, 40) is capable of supporting at least one service for one of a plurality of subscriber units (30–36, 42–46). The determination is based on whether the service provider has sufficient processing capabilities and memory to receive the service processing software from the subscriber unit and/or whether the service provider is authorized, based on communication system policies to process the particular service request for this subscriber. If the service provider is capable, the subscriber unit provides service processing logic (e.g., the service processing application and/or user customization software) to the service provider. Upon receiving the service processing logic, the service provider stores it and eventually executes it to process the requested service for the subscriber units.

摘要： The present invention encompasses a method of facilitating talkgroup communications across a multiple-system communication network (100). A typical multi-system network (100) includes a plurality of communication units (122), a plurality of communication location areas (117-119), and a plurality of system controllers (100, 116). Upon migration of a communication unit (122) from one communication system to another, the communication unit (122) sends a registration request to the system controller (116) at the new communication system (102). The system controller (116) determines whether the talkgroup of the migrating communication unit (122) is registered with the new communication system (102). If the talkgroup is not registered with the new system (102), a database (120) is updated with the new talkgroup information, thereby facilitating talkgroup communication involving, members of the talkgroup.
