摘要： In a wireless code-division multiple access (CDMA) system (100), a talkgroup (101) of subscriber units is provided. A sub-talkgroup (102) of subscriber units, forming a part of the talkgroup is assigned at least one inbound channel (416-417). The talkgroup is assigned outbond channels (415). Members of the sub-talkgroup may simultaneously transmit voice information (410-411) using the at least one inbound channel, which voice information is summed (412) and re-transmitted to the talkgroup using the outbound channels. Voice information is summed so that an individual talker receives summed voice information without the individual subscriber's voice content. Subscriber units in the sub-listengroup are allowed to transmit voice information only after requesting, and receiving, an additional inbound channel.
摘要翻译：在无线码分多址（CDMA）系统（100）中，提供了用户单元的谈话组（101）。构成通话组的一部分的用户单元的分通话组（102）被分配至少一个入站信道（416-417）。谈话组被分配outbond频道（415）。分通话组的成员可以使用至少一个入站信道同时发送语音信息（410-411），该语音信息被求和（412）并且使用出站信道重发到谈话组。对语音信息进行求和，以便个人讲话者在没有个人用户的语音内容的情况下接收总和的语音信息。允许子收听群中的用户单元仅在请求和接收额外的入站信道之后才传送语音信息。

摘要： A method and apparatus for synchronized hand off from a cellular network (138) to a wireless network (100) includes an antenna (110) capable of receiving a synchronization channel and a pilot channel (112). Within the wireless network (100) is an access point (104) and a cellular timing recovery receiver (106) coupled to the antenna (110). The cellular timing recovery receiver (106) receives the synchronization channel and the pilot channel (112), which are provided to the access point (104) from a cellular base station (114). The cellular timing recovery receiver (106) thereupon generates a clock pulse (120) and a clock setting signal (122) which are provided to the access point (104), which are utilized to synchronize an internal clock with respect to the timing of the cellular base station (114). Thereupon, the wireless area network (100) may be synchronized with a cellular network (138) message information (150c).
摘要翻译：一种用于从蜂窝网络（138）到无线网络（100）的同步切换的方法和装置包括能够接收同步信道和导频信道（112）的天线（110）。在无线网络（100）内是与天线（110）耦合的接入点（104）和蜂窝定时恢复接收机（106）。蜂窝定时恢复接收机（106）从蜂窝基站（114）接收提供给接入点（104）的同步信道和导频信道（112）。蜂窝定时恢复接收机（106）随后产生提供给接入点（104）的时钟脉冲（120）和时钟设置信号（122），其用于使内部时钟相对于蜂窝基站（114）。因此，无线区域网络（100）可以与蜂窝网络（138）消息信息（150c）同步。
