1. In a CDMA communication system, a method for supporting handoff of a terminal between base stations of different protocol revisions, comprising:
performing a handoff of the terminal from a first base station to a second base station, wherein the handoff is performed while the terminal is in an active call using a first service configuration with the first base station, and wherein the first base station supports a first protocol revision and the second base station supports a second protocol revision that is later than the first protocol revision; sending a first message indicative of a change in packet zone; receiving a request to originate a new call with a second service configuration and a proposed service reference identifier, wherein a prior call was established at the terminal with the second service configuration that became dormant before the handoff, the prior call being associated with a service reference identifier different from the proposed service reference identifier; and maintaining the new call with the second service configuration and the proposed service reference identifier between the terminal and the second base station. |
