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.
