摘要： The system requires the use of the permanent ID of the requesting unit in every channel request made on a control channel before every transmission. The channel grant will include the ID along with the channel number and these may be recorded for possible later reference. A channel assignment is retained for a brief period after each transmission, allowing a conversation to be continued on the same channel without a break. Units can access the control channel with a channel request and be assigned a channel even while the dispatcher is using the voice channel. In the case of a need for communication with a larger group, a dispatcher can form a temporary "patch" group of all involved units, with a temporary ID assigned to that group. A channel request from a member of the larger group must then include, not only the permanent ID of the requesting unit, but the temporary ID of the "patch" group.

摘要翻译： 在每个传输之前，系统需要在控制信道上进行的每个信道请求中使用请求单元的永久ID。 频道授权将包括ID以及频道号，并且可以记录这些ID以供将来参考。 频道分配在每次传输后的短时间内保留，允许在同一频道上继续进行会话，而不会中断。 单元可以使用通道请求访问控制通道，即使在调度程序使用语音通道时也可以分配通道。 在需要与较大组通信的情况下，调度员可以形成所有相关单元的临时“补丁”组，并将临时ID分配给该组。 来自较大组的成员的信道请求必须不仅包括请求单元的永久ID，而且还包括“补丁”组的临时ID。
