Abstract: Alternative messages are transmitted in a time slot (e.g.3) of a frame of a time division multiple access communications system during periods of silence or when no speech data is present. When an absence of voice is detected, an abbreviated message (60) is substituted for a longer message in the time slot (31). In subsequent frames, the shorter message (60) is also substituted for the longer message until voice is detected.

Abstract translation: 在静默期间或当没有语音数据存在时，在时分多址通信系统的帧的时隙（例如3）中发送替代消息。 当检测到不存在语音时，在时隙（31）中代替较短的消息（60）。 在随后的帧中，更短的消息（60）也替代较长的消息，直到检测到语音。

Abstract: Sharing the existing sector antennas at the base station each of which corresponds to one sector of the outer communication coverage area to create an omnidirectional inner communication coverage area. When transmitting or receiving data from a mobile in one sector of the outer communication coverage area only one antenna is used, and when transmitting or receiving data from a mobile in the inner communication coverage area all the antennas are used. This allows an increase in capacity of the hybrid inner/outer sectored cell without the additional cost of adding further antennas.

Abstract translation: 共享基站处的现有扇区天线，每个天线对应于外部通信覆盖区域的一个扇区，以创建全向内部通信覆盖区域。 当从外部通信覆盖区域的一个扇区中的移动站发送或接收数据时，仅使用一个天线，并且当在内部通信覆盖区域中的移动站发送或接收数据时，使用所有天线。 这允许混合内部/外部扇区的容量的增加，而不增加额外的天线的额外成本。

Abstract: In a cellular system, channels are assigned for new calls using a flexible channel allocation algorithm that is a hybrid of a measurement-based dynamic channel assignment (MBDCA) algorithm and a reuse-distance criterion algorithm, such as a cost-function-based DCA (CFBDCA). In one embodiment, the MBDCA algorithm is implemented at each cell site in the cellular system and generates a list of candidate channels for each new call. The list is transmitted to the mobile switching center (MSC), which implements the CFBDCA algorithm to select a particular channel from the list of candidate channels for the new call.
