Abstract: A GPRS controller interface communicates commands, events and data between two communication devices using a GPRS transport layer (GTL). In one embodiment, communication devices may include a host and a baseband controller of a modem that communicate over a serial link. Command event and data packets may be framed and multiplexed for transmission over the link. The framing includes, among other things, adding a flag to identify command and event packets from data packets, and a sequence number to help ensure synchronization. A first logical channel may be utilized for command packets including AT modem commands. A second logical channel may be utilized for outbound data packets. A third logical channel may be utilized for event packets, and a fourth logical channel may be utilized for inbound data packets. GTL commands may initiate an initialization or resynchronization of the GCI layer and may be generated, for example, in response to sequence number errors of check-byte errors.

Abstract translation: GPRS控制器接口使用GPRS传输层（GTL）在两个通信设备之间传送命令，事件和数据。 在一个实施例中，通信设备可以包括通过串行链路通信的调制解调器的主机和基带控制器。 命令事件和数据分组可以被成帧和多路复用以在链路上传输。 框架包括添加标识来识别来自数据分组的命令和事件分组以及用于确保同步的序列号。 第一逻辑信道可以用于包括AT调制解调器命令的命令分组。 第二逻辑信道可以用于出站数据分组。 可以将第三逻辑信道用于事件分组，并且第四逻辑信道可用于入站数据分组。 GTL命令可以启动GCI层的初始化或重新同步，并且可以例如响应于校验字节错误的序列号错误而产生。
