    Abstract: To address the need for dispatch in a CDMA communication system, each mobile unit (309, 319) and CBSC (301, 311) involved in a call are allowed to establish an independent RLP session between them. Each session contains its own unique RLP sequence numbers that are not shared. Reverse link sequence numbers are passed from the source CBSC (301, 311) (serving the "talking" mobile) to the target CBSC(s) (301, 311) (serving the "listening" mobiles). However, instead of being directly used by the target CBSC(s) (301, 311) for its forward link RLP sequence number, the sequence numbers passed to the CBSC (301, 311) is translated to the existing target CBSCs (301, 311) current RLP sequence numbers.

    Abstract translation: 为了解决CDMA通信系统中的调度需求,允许呼叫中涉及的每个移动单元(309,319)和CBSC(301,311)在它们之间建立独立的RLP会话。 每个会话都包含不共享的唯一RLP序列号。 反向链路序列号从源CBSC(301,311)(服务于“通话”移动台)传送到目标CBSC(301,311)(服务于“收听”移动台)。 然而,不是由目标CBSC(301,311)直接使用其前向链路RLP序列号,而是将传递给CBSC(301,311)的序列号转换成现有目标CBSC(301,311) )当前RLP序列号。

    Abstract: A method and apparatus for packet alignment in a simulcast system includes a communications controller (310) having a vocoder and an input/output (I/O) processor (313) controlling the vocoder (311), the I/O processor having a timing alignment control (315) and a packet counter (314) for inserting timing alignment tags in voice/data packets and adjusting packet numbering and timing based on alignment requests from a master radio communication unit. The communications controller is coupled to radio communication units (330, 340, 350), each having a packet buffer (331) and an alignment processor (332) which includes a packet number detector (333) for detecting the transmission timing tag and sending a request for a packet numbering adjustment to the communications controller and a timing alignment detector (334) for comparing a receive time of the first information packet and a predetermined preferential receive time and for sending a timing alignment request to the communications controller.

    Abstract: A method and system for time aligning a frame (60) in a communication network (10) involves the steps of; i) determining if a frame needs to be advanced at a BTS (14), and ii) sending a shortened synchronization pattern from the BSC (12). The BTS (14) then determines if a short or long synchronization pattern has been sent by determining (256) if the received data stream matches a long synchronization pattern and setting a first flag when they do match. If the received data stream does not match the long synchronization pattern and the first flag is set (264), the data stream is compared (266) to the short synchronization pattern. When they match a second flag is set (268).
