摘要： An apparatus and method for displaying identity information of a last speaker in a push-to-talk (PTT) system. A wireless communication device receives PTT communications and identification information of PTT speakers from a remote server. The wireless communication device displays the identification information of at least the last speaker while playing the PTT communication from a current speaker.

摘要： A method and apparatus for providing privacy of user identity and characteristics in a communication system. A public key and a private key is generated, corresponding to a transceiver. The public key is transmitted to a wireless communication device. The wireless communication device encrypts one or more an initial messages using the public key and transmits the one or more encrypted initial messages to the transceiver. The transceiver receives the one or more encrypted initial messages and decrypts it using the private key. The transceiver may then allocate resources to initiate a desired communication between said wireless communication device and a second communication device.

摘要： A method and apparatus for joining a user to a call in a group communication network provides for receiving an indication from a user who wishes to initiate a group call and sending a request to a server to add the user to the group call if the group call is in progress. The method and apparatus also provides for receiving a response from the server indicating that the group call is in progress, alerting the user of being added to the group call, and receiving media from the server after a traffic channel is re-established. The method and apparatus also provides for a significant reduction in the actual total dormancy wakeup time and latency by exchanging group call signaling even when mobiles are dormant and no traffic channel is active.

摘要： A method and apparatus for providing fair access to members of a group communication system in which the members experience differing signaling delays. Members of the communication system send a transmission request to an arbitration device when they wish to communicate with other members. The transmission requests are ultimately received by the arbitration device. A time window is opened by a processor located at the arbitration device at the time an initial transmission request is received. The time window is used to treat all transmission requests that are received within the time window as having been received at the same time. Any transmission requests that are received within the time window are included in determining which member should be granted an exclusive transmission privilege.

摘要： A method and apparatus for providing fair access in a group communication system. Permission to transmit is based on a variable-level priority scheme. The variable priority level of each member in the system is based upon the number of event occurrences that have occurred in the past. In a first embodiment, the number of event occurrences is defined as the number of times that a member has been denied permission to transmit. The more denials that a member accumulates, the higher an corresponding priority level becomes. In a second embodiment, the priority level is based on the amount of time which has elapsed from when a net member was last granted the transmission privilege. The greater the time differential between when a member has last been granted the transmission privilege and a present access request, the greater the variable priority level becomes.

摘要翻译： 一种用于在组通信系统中提供公平接入的方法和装置。 发送权限是基于可变级优先级方案。 系统中每个成员的可变优先级基于过去发生的事件发生次数。 在第一实施例中，事件发生的次数被定义为成员被拒绝发送的次数。 成员累积的否认越多，相应的优先级越高。 在第二实施例中，优先级基于从最后一个网络成员授予传输权限起经过的时间量。 成员最后被授予传输权限和当前访问请求之间的时间差越大，变量优先级越高。
