Claim 9

A method for informing a remote unit of a feature-originated call in a communication system where there exist a plurality of types of feature-originated calls, wherein the feature-originated call is being placed to the remote unit in response to a utilized feature service, the method comprising the steps of: determining, by wireless infrastructure equipment in response to the utilized feature service that the feature-originated call needs to be provided to the remote unit to produce a feature service determination; determining an availability of the remote unit to produce an availability determination; determining a feature indication message based on the feature service determination, wherein the feature indication message is utilized to provide the remote unit with an indication of a specific type of feature-originated call from the plurality of feature-originated calls that needs to be provided to the remote unit; determining a time period to send the feature indication message to the remote unit contacting the remote unit via a downlink communication signal; and simultaneously supplying the remote unit the feature indication message via the downlink communication signal and sending the feature-originated call to the remote unit to provide the remote unit with an indication of a type of feature-originated call, wherein the step of supplying and sending is based on the time period, the feature indication message, and the availability of the remote unit and is sent to the remote unit prior to providing the feature-originated call to the remote unit.

Claim 10

A method for informing a remote unit of a feature-originated call in a communication system where there exist a plurality of types of feature-originated calls, wherein the feature-originated call is being placed to the remote unit in response to a utilized feature service, the method comprising the steps of: determining, by wireless infrastructure equipment in response to the utilized feature service that the feature-originated call needs to be provided to the remote unit to produce a feature service determination; determining an availability of the remote unit to produce an availability determination; determining a feature indication message based on the feature service determination, wherein the feature indication message is utilized to provide the remote unit with an indication of a specific type of feature-originated call from the plurality of feature-originated calls that needs to be provided to the remote unit; determining a time period to send the feature indication message to the remote unit contacting the remote unit via a downlink communication signal; and simultaneously supplying the remote unit the feature indication message via the downlink communication signal and sending the feature-originated call to the remote unit to provide the remote unit with an indication of a type of feature-originated call, wherein the step of supplying and sending is based on the time period, the feature indication message, and the availability of the remote unit and is sent to the remote unit prior to providing the feature-originated call to the remote unit.

Claim 17

An apparatus for informing a remote unit of a feature-originated call in a communication system where there exist a plurality of types of feature-originated calls, the apparatus comprising: a Mobile Switching Center (MSC) for determining an availability of the remote unit to produce an availability determination; a trigger manager coupled to the MSC, the trigger manager determining a feature indication message based on the feature-originated call, wherein the feature indication message is utilized to provide the remote unit with an indication of the specific type of feature-originated call from the plurality of feature-originated calls that needs to be provided to the remote unit, the trigger manager additionally determining a time period to send the feature indication message to the remote unit; a controller coupled to the MSC for contacting the remote unit via a downlink communication signal; a base station coupled to the MSC, the base station simultaneously supplying the remote unit the feature indication message and the feature-originated call via a downlink communication signal, wherein the step of supplying is based on the time period, the feature indication message, and the availability of the remote unit and is sent to the remote unit prior to providing the feature-originated call to the remote unit.

Claim 18

An apparatus for informing a remote unit of a feature-originated call in a communication system where there exist a plurality of types of feature-originated calls, the apparatus comprising: a Mobile Switching Center (MSC) for determining an availability of the remote unit to produce an availability determination; a trigger manager coupled to the MSC, the trigger manager determining a feature indication message based on the feature-originated call, wherein the feature indication message is utilized to provide the remote unit with an indication of the specific type of feature-originated call from the plurality of feature-originated calls that needs to be provided to the remote unit, the trigger manager additionally determining a time period to send the feature indication message to the remote unit; a controller coupled to the MSC for contacting the remote unit via a downlink communication signal; a base station coupled to the MSC, the base station simultaneously supplying the remote unit the feature indication message and the feature-originated call via a downlink communication signal, wherein the step of supplying is based on the time period, the feature indication message, and the availability of the remote unit and is sent to the remote unit prior to providing the feature-originated call to the remote unit.
