摘要： A method and apparatus for reliable wireless voice, data and location communication for deployment in underground, industrial and other hazardous environments using a wireless mesh network. The network includes protocol for dispatch operation, emergency operation, remote supervision, remote status, asset control, machine state of health and operational management. The architecture is based on localized clusters of autonomous nodes capable of ad hoc interconnection with nearby nodes and connection to gateway nodes. The resulting network is an ad hoc mesh topology comprised of fixed mesh nodes with approximately 50% coverage overlap between nodes. This provides a reliable communication network for mobile nodes carried by personnel and sensor nodes that are fixed or mobile that supports voice, data and tracking/situation awareness. Each cluster of nodes transfers digital voice and data to gateway nodes either directly or through multi-hop transactions.

摘要： A method for forming a protocol structure for use in an ad hoc, distributed, scaleable wireless sensor node network which enables nodes to join the network autonomously without there being a designated, permanent central time reference and for enabling such nodes to synchronize timing with each other and with other nodes in the network. The method involves discovering the active channel changing sequence used by the network, synchronizing communications of a new node with the remainder of the nodes in the network and scanning communications channels to detect merging clusters of nodes.

摘要： A group call server supplies communications terminals of a certain type with an indication of call type, and optionally other information, for group calls so as to distinguish such calls from other types of calls. The group call server in charge of the group call may selectively augment the calling party number field of the outgoing paging message with one or more indicator flags when the targeted communications terminal is adapted to receive and act upon such information. The indicator flags indicate one or more characteristics of the group call, such as call type, call subtype, or priority level. One flag may indicate priority level and another may indicate the call subtype of the group call. The communications terminals receiving the augmented paging message will base their response, such as to auto-answer or not, on the group call characteristics indicated in the paging message. The group call server may rely on already built-in flexibility in existing signaling and air interface protocols so that the method disclosed herein may be implemented without the need to change the air interface or the BMI.

摘要： A communications terminal, such as a wireless mobile terminal, is supplied with an indication of group call characteristics for incoming group calls so as to distinguish such calls from other types of incoming calls. A Group Call Server in charge of the group call may selectively augment the calling party number field of the paging message with one or more indicator “flag characters,” indicating one or more characteristics of the group call, such as call type, call subtype, or priority level. The communications terminal receives the group call paging message and selects the appropriate response to the paging message based on the flag characters. The communications terminal preferably examines the calling party field of the paging message and notes the presence of the flag characters. When the flag characters are present, the communications terminal parses out the flag characters and calling party ID. Based on the flag characters, the communications terminal determines the proper response to the paging message. This response may include, for instance, controlling the man-machine interface of the communications terminal and determining whether or not to automatically answer the call. For instance, the communications terminal may automatically answer group calls of certain kind(s) and require manual intervention of the user prior to answering the paging call for other kind(s). Thus, the communications terminals receiving the augmented paging message will base their response, such as whether to auto-answer or not, on the group call characteristics indicated in the paging message.
摘要翻译： 诸如无线移动终端的通信终端被提供有用于进入组呼叫的组呼叫特性的指示，以便将这种呼叫与其他类型的呼入区分开来。 负责群组呼叫的群呼服务器可以利用一个或多个指示符“标志字符”来选择性地增加寻呼消息的呼叫方号码字段，该指示符指示该群组呼叫的一个或多个特征，诸如呼叫类型，呼叫子类型， 或优先级。 通信终端接收组呼叫寻呼消息，并根据标志字符选择对寻呼消息的适当响应。 通信终端优选地检查寻呼消息的呼叫方字段并注意标志字符的存在。 当标志字符存在时，通信终端解析出标志字符和主叫方ID。 基于标志字符，通信终端确定对寻呼消息的适当响应。 该响应可以包括例如控制通信终端的人机界面并确定是否自动应答呼叫。 例如，通信终端可以在应答其他类型的寻呼呼叫之前自动应答某些种类的组呼，并且需要用户的手动干预。 因此，接收增强寻呼消息的通信终端将基于在寻呼消息中指示的组呼叫特性的响应，例如是否自动应答。

摘要： A simplified method of assigning a call address to a PTT key for speed dialing in radio mode. The existing call addresses stored in memory are reviewed by the user and one of the call addresses is chosen as the default call address. This default call address is associated with a particular hot key, such as the PTT key. Thereafter, when the hot key is pressed to initiate a call without another call address currently pending, the default call address is used to initiate the call in radio mode. In preferred embodiments, the user may assign the call address to be the default without having to move the call address information from one memory location to another. Likewise, the user may change the call address assigned to be the default without having to move the call address information from one memory location to another. Thus, the present invention provides a simpler and less error prone procedure.
摘要翻译： 将无线电模式中的快速拨号的呼叫地址分配给PTT密钥的简化方法。 存储在存储器中的现有呼叫地址由用户审查，并且其中一个呼叫地址被选择为默认呼叫地址。 此默认呼叫地址与特定热键（如PTT键）相关联。 此后，当热键被按下以发起没有另一呼叫地址正在等待的呼叫时，默认呼叫地址用于以无线电模式发起呼叫。 在优选实施例中，用户可以将呼叫地址分配为默认，而不必将呼叫地址信息从一个存储器位置移动到另一个存储器位置。 同样地，用户可以改变被分配为默认的呼叫地址，而不必将呼叫地址信息从一个存储器位置移动到另一个存储器位置。 因此，本发明提供了一种更简单且更容易出错的过程。

摘要： A simplified method of controlling the operating mode of a wireless communications device, particularly the speaker mode, includes operating a wireless communications device according to a selected default mode. The method of audio output, such as through a loud speaker or through a quieter speaker, is determined, at least in part by the default mode setting. The device includes at least a first key and a second key. Pressing the first key causes the device to automatically initiate a call session in radio mode and stay in radio mode until the end of the call session. On the other hand, pressing the second key causes the device to automatically initiate a call session in phone mode and stay in phone mode until the end of the call session. In either case, the wireless communications device reverts to the default mode when the call session ends. By doing so, the user is provided with a simple method for temporarily switching to the desired mode of operation, without the necessity of first determining the current mode of the wireless communications device and through the simple press of a single key. This method is particularly adapted for use with wireless communications devices having two separate speakers, a quiet one for phone mode and a louder one for radio mode.

摘要： The invention includes a method for processing group calls. A group list is created having a plurality of group members and preferably includes for each group member whether the group member requires an affirmative response when contacted, and an identifier. A request is received from an originator to contact the group members. At least one of the group members is contacted, and an affirmative response is requested. After receiving the affirmative response, the originator and group member are connected. If no affirmative response is received, the group member is not connected with the originator.
