摘要： Methods of enabling late entry into an on-going spread spectrum call are described. A late join frame replaces, and has the same size as, a traffic frame. A late join slot in the late join frame contains sufficient information in preamble and sync subframes to permit a target to join the call. The traffic slots in the late join frame replicate data such that call quality of the call is substantially unaffected if one of the remaining traffic frames is not received. The preamble and sync subframes frequencies may be the same as, or different from, preamble and sync frames frequencies during a call establishment phase of the call. If different, the preamble and sync subframes frequencies are selected from one or more frequencies. Use of the preamble and sync subframes frequencies is compensated for when selecting the traffic slot frequencies to obtain uniform utilization of the spectrum.

摘要： A digital radio communication system (200) uses a repeater (216) to relay calls which can not be completed in a direct talk-around mode between two radios. The repeater (216) establishes early synchronization in advance of a pending call by listening to an originator radio (204) attempt to make a direct talk-around call to a target radio (210). Asynchronous digital two-way radio communication systems can benefit from the reduction in voice call connect time.
摘要翻译： 数字无线电通信系统（200）使用中继器（216）来中继在两个无线电之间的直接通话模式中不能完成的呼叫。 中继器（216）通过收听发起者无线电（204）尝试对目标无线电（210）进行直接通话呼叫，在未决呼叫之前建立早期同步。 异步数字双向无线电通信系统可以从语音呼叫连接时间的减少中获益。

摘要： A communication device (105,200) includes a cordless telephone (205) and a two way radio (210). The communication device (105,200) is adapted to place an active cordless telephone call in a low frequency mode in response to receiving an incoming two way radio communication. The communication device (105,200) is adapted to then establish communication within the two way radio communication. The communication device (105,200) periodically re-establishes the cordless telephone call to maintain communication with a cordless base station (120) until the two way radio communication is completed.
