Abstract
An implementation of packet data control protocol (PDCP) parameter negotiation in a universal mobile telephone communications service (UMTS) which can also be used to improve GSM/GPRS XID negotiation methods, where the timing for exactly when the new parameters are to take effect must be known includes either a GPRS-type reset solution or a PDCP-header based change indicator solution. In the GPRS-type reset solution, PDCP negotiations are made and then connections are reset to put into effect the new PDCP parameters for use. The second solution is to add a change indicator, e.g., a bit (C-bit) to the PDCP-PDU's header part. The originator informs using this bit that new parameter values are to take effect for use.
