Handoff between base stations of different protocol revisions in a CDMA system

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 with the first base station using a first service configuration, 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;
• purging the first service configuration used for the active call prior to the handoff;
• and
• maintaining the active call between the terminal and the second base station after the handoff using a second service configuration supported by the second protocol revision.

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 with the first base station using a first service configuration, 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;
• releasing the active call by the second base station;
• receiving a request to originate a new call with a second service configuration;
• and
• maintaining the new call between the terminal and the second base station using the second service configuration.

• 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
• maintaining the new call with the second service configuration between the terminal and the second base station.

A memory communicatively coupled to a digital signal processing device (DSPD) capable of interpreting digital information to:

• perform a handoff of a terminal from a first base station to a second base station in a CDMA communication system, wherein the handoff is performed while the terminal is in an active call with the first base station using a first service configuration, 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;
• purge the first service configuration used for the active call prior to the handoff;
• and
• maintain the active call between the terminal and the second base station after the handoff using a second service configuration supported by the second protocol revision.

A computer program product for supporting handoff of a terminal between base stations of different protocol revisions, comprising:

• code for 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 with the first base station using a first service configuration, 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;
• code for purging the first service configuration used for the active call prior to the handoff;
• code for maintaining the active call between the terminal and the second base station after the handoff using a second service configuration supported by the second protocol revision;
• and
• a computer-usable medium for storing the codes.

A terminal in a CDMA communication system, comprising:

• means for performing a handoff from a first base station to a second base station in the CDMA system, wherein the handoff is performed while the terminal is in an active call with the first base station using a first service configuration, 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;
• means for purging the first service configuration used for the active call prior to the handoff;
• and
• means for maintaining the active call with the second base station after the handoff using a second service configuration supported by the second protocol revision.
