Method and apparatus for reducing a processing delay in a two-way messaging system

Claim 3

The method of claim 1, wherein the operating step includes the step of scheduling messages to and from the portable subscriber unit.

Claim 4

The method of claim 1, wherein the operating step includes the step of utilizing a messaging agent execution platform installed in the destination control element for cooperating with the messaging agent to process the portion of the interactive application.

Claim 5

The method of claim 1, further comprising in the messaging control center the steps of: checking, before executing the passing step, whether the messaging agent is already present at the destination control element; and skipping the passing step in response to determining in the checking step that the messaging agent is already present at the destination control element.

Claim 6

The method of claim 1, wherein the selecting step comprises the step of selecting the messaging control center itself as the source, and wherein the passing step is skipped, as being unnecessary.

Claim 7

The method of claim 1, wherein the selecting step is performed by another of the plurality of intelligent control elements instead of by the messaging control center.

Claim 8

The method of claim 1, further comprising the step of downloading, by the source, a frequently used messaging agent to selected ones of the plurality of intelligent control elements, where the messaging agent remains on a long-term basis.

Claim 11

A two-way radio messaging system for reducing a delay in processing an interactive application for a portable subscriber unit, the system having a distributed architecture, the system comprising: a plurality of intelligent control elements, comprising: a messaging control center for controlling the two-way radio messaging system; a base station controller coupled to the messaging control center for controlling a base station; a base station transmitter coupled to the base station controller for transmitting a message to the portable subscriber unit; a base station receiver coupled to the base station controller for receiving a message from the portable subscriber unit; and the portable subscriber unit coupled by radio to the base station transmitter and receiver for communicating therewith, wherein the portable subscriber unit is programmed to send a request to the messaging control center to ship a software messaging agent to one of the plurality of intelligent control elements near the portable subscriber unit for processing an interactive application, and wherein the messaging control center is programmed to: select a source and a destination control element that will minimize communications required to process the interactive application; and pass the request to the source to download the messaging agent to the destination control element, and wherein the destination control element is programmed to operate the messaging agent to autonomously process at least a portion of the interactive application, thereby reducing processing delay resulting from communication latency.

Claim 12

A two-way radio messaging system for reducing a delay in processing an interactive application for a portable subscriber unit, the system having a distributed architecture, the system comprising: a plurality of intelligent control elements, comprising: a messaging control center for controlling the two-way radio messaging system; a base station controller coupled to the messaging control center for controlling a base station; a base station transmitter coupled to the base station controller for transmitting a message to the portable subscriber unit; a base station receiver coupled to the base station controller for receiving a message from the portable subscriber unit; and the portable subscriber unit coupled by radio to the base station transmitter and receiver for communicating therewith, wherein the portable subscriber unit is programmed to send a request to the messaging control center to ship a software messaging agent to one of the plurality of intelligent control elements near the portable subscriber unit for processing an interactive application, and wherein the messaging control center is programmed to: select a source and a destination control element that will minimize communications required to process the interactive application; and pass the request to the source to download the messaging agent to the destination control element, and wherein the destination control element is programmed to operate the messaging agent to autonomously process at least a portion of the interactive application, thereby reducing processing delay resulting from communication latency.

Claim 13

The two-way radio messaging system of claim 9, further comprising a host computer coupled to the messaging control center for sending the software messaging agent thereto.

Claim 14

The two-way radio messaging system of claim 9, wherein the destination control element is further programmed to schedule messages to and from the portable subscriber unit.

Claim 15

The two-way radio messaging system of claim 9, wherein the destination control element comprises a messaging agent execution platform for cooperating with the messaging agent to process the portion of the interactive application.

Claim 16

The two-way radio messaging system of claim 9, wherein the messaging control center is further programmed to: check whether the messaging agent is already present at the destination control element; and skip passing the request to the source in response to determining that the messaging agent is already present at the destination control element.

Claim 17

The two-way radio messaging system of claim 9, wherein the messaging control center, when it has the messaging agent stored within itself, is further programmed to: select itself as the source of the messaging agent; and skip passing the request to the source to download the messaging agent.

Claim 18

The two-way radio messaging system of claim 9, wherein another one of the plurality of intelligent control elements different from the messaging control center is programmed to select the source and the destination control element.

Claim 19

The two-way radio messaging system of claim 9, wherein the source is programmed to download a frequently used messaging agent to selected ones of the plurality of intelligent control elements, where the messaging agent is intended to remain on a long-term basis.

Claim 20

The two-way radio messaging system of claim 9, wherein the portable subscriber unit is further programmed to: select the destination control element; ship a first software messaging agent to the destination control element for processing the interactive application; and send the request to ship a second software messaging agent to the destination control element for interaction with the first messaging agent, and wherein the destination control element is further programmed to operate the first and second messaging agents such that they interact with one another to process at least the portion of the interactive application.
