Method of constructing a QuickConfig message in a 1xEvolution Data Only (1xEV-DO) communication network and method of reducing call and handoff failure rates in the 1xEV-DO network without introducing additional call setup latencies
View Patent ↗In a method of constructing a QuickConfig message in a 1x Evolution (1XEV) data only (EV-DO) communication network for broadcast by a base station of the network to a plurality of users served thereby, a Forward Traffic Valid (FTValid) bit in a field of the QuickConfig message is set to a default value of a logic high state for all users. No delay occurs for a call setup between a given user and the base station even if the user requests the call setup after the QuickConfig message has been constructed by the base station.
1. A method of constructing a QuickConfig message in a 1x Evolution (1XEV) data only (EV-DO) communication network for broadcast by a base station of the network to a plurality of users served thereby, comprising:
setting a Forward Traffic Valid (FTValid) bit in a field of the QuickConfig message to a default value of a logic high state for all users,
if the network does not have confirmation that a given user has closed its connection, maintaining a Media Access Control Index (MACIndex) resource for the given user at the base station for a given period M, at the end of which the MACIndex is de-allocated, and
toggling the FTValid bit to a logic low state during the period M so that the given user monitors the bit according to its assigned MacIndex and drops the call.
2. The method of claim 1 , wherein any user requesting to set up a call between a time when the base station is commanded to construct the QuickConfig message and a time at which the constructed QuickConfig message is broadcast to the users receives the QuickConfig message with the FTValid bit set to the default logic high.
3. The method of claim 1 , further comprising, if the network has confirmation that a given user has closed its connection to the network,
maintaining the FTValid bit in the QuickConfig at its default value of the logic high state.
4. A method of reducing call and handoff failure rates in a 1xEV-DO communication network without introducing additional call setup latencies, comprising:
setting a FTValid bit in a field of the QuickConfig message being constructed by a base station of the network to a default value of a logic high state for all users being served by the base station in the network,
transmitting the QuickConfig message to the users being served thereby, wherein no delay occurs for a call setup between a given user and the base station even if the user requests the call setup after the QuickConfig message has been constructed by the base station,
if the network does not have confirmation that a given user has closed its connection, maintaining a Media Access Control Index (MACIndex) resource for the given user at the base station for a given period M, at the end of which the MACIndex is de-allocated, and
toggling the FTValid bit to a logic low state during the period M so that the given user monitors the bit according to its assigned MACIndex and drops the call.
5. The method of claim 4 , wherein any user requesting to set up a call between a time when the base station is commanded to construct the QuickConfig message and a time at which the constructed QuickConfig message is broadcast to the users receives the QuickConfig message with the FTValid bit set to the default logic high.
6. The method of claim 4 , further comprising, if the network has confirmation that a given user has closed its connection to the network,
maintaining the FTValid bit in the QuickConfig at its default value of the logic high state.
