Abstract

A mobile switching center (MSC) in accordance with the principles of the present invention provides access to a subscribers voice message center from the subscriber'"'"'s roaming mobile station. The MSC is responsive to a “RemoteFeatureRequest” Invocation by the roaming mobile station in which the subscriber'"'"'s directory number is the same as the dialed digits by routing the call from the mobile station to the subscriber'"'"'s voice message center. The MSC may also be responsive to a “OriginationRequest” employing the subscriber'"'"'s directory number as the dialed digits by routing the roaming mobile station'"'"'s call to the subscriber'"'"'s voice message center. If the MSC supports both RemoteFeatureRequest-, and OriginationRequest-based access to the subscriber'"'"'s voice message center, the MSC determines which of the approaches to use in response to the reception of a subscriber'"'"'s directory number as the dialed digits from the subscriber'"'"'s roaming mobile station. The MSC may make this determination on the basis of information stored in a local database that indicates the method employed by other telecommunications devices, such as other MSCs, Visiting Location Registers (VLR), or Home Location Registers (HLR), within the system. One of the methods, that is, the use of an Origination Invocation or the use of a RemoteFeatureRequest invocation, may be chosen as a default method.

Claims

1. Apparatus responsive to communications from a mobile station comprising:

a database stored within a mobile telecommunications system the database including a mobile identifier associated with a mobile station;

the database further including an indication that the apparatus is responsive to communications from a mobile station in which the mobile station sends its directory number as dialed digits by employing a RemoteFeatureRequest Invocation to connect the mobile station with the mobile station'"'"'s voice messaging system; and

,

a controller which is responsive to communications from a mobile station in which the mobile station sends its directory number as dialed digits by determining whether to employ a RemoteFeatureRequest Invocation or an OriginationRequest Invocation to connect the mobile station with the mobile station'"'"'s voice messaging system.

2. The apparatus of claim 1 wherein the controller is an MSC.

3. The apparatus of claim 2 wherein the MSC comprises means for retrieving the indication that the apparatus is responsive to communications from a mobile station in which the mobile station sends its directory number as dialed digits by employing a RemoteFeatureRequest Invocation to connect the mobile station with the mobile station'"'"'s voice messaging system.

4. The apparatus of claim 3 further comprising a means for determining whether RemoteFeatureRequest or OriginationRequest is to be used to provide access to a roaming station'"'"'s voice mail system.

5. The apparatus of claim 3 further comprising a means for establishing a connection between a roaming mobile station and the mobile station'"'"'s voice mail system.

6. The apparatus of claim 5 further comprising a home location register (HLR) that is responsive to the reception of a RemoteFeatureRequest by returning a mobile station'"'"'s voice mail system routing information in a return result.

7. The apparatus of claim 6 wherein the HLR is responsive to the reception of an OriginationRequest by returning a mobile station'"'"'s voice mail system routing information in a return result.

8. A method comprising the steps of:

storing RemoteFeatureRequest data in a mobile switching center (MSC), the RemoteFeatureRequest data indicating that a RemoteFeatureRequest Invocation should be employed to connect a roaming mobile station with the mobile station'"'"'s voice mail system;

retrieving the RemoteFeatureRequest data in response to the reception of a mobile station'"'"'s directory number as the dialed digits from the same mobile station while that station is roaming; and

,

examining data within the MSC to determine whether a RemoteFeatureRequest Invocation or an OriginationRequest Invocation should be employed to provide access to the voice mail system for the mobile station.

9. The method of claim 8 further comprising the step of:

sending a RemoteFeatureRequest Invocation to the mobile station'"'"'s home location register (HLR) in response to the reception of a mobile station'"'"'s directory number as the dialed digits from the same mobile station while that station is roaming if it is determined during the data examination that the RemoteFeatureRequest Invocation should be employed to provide access to the voice mail system for the mobile station.

10. The method of claim 8 further comprising the step of:

sending an OriginationRequest Invocation to the mobile station'"'"'s home location register (HLR) in response to the reception of a mobile station'"'"'s directory number as dialed digits from the same mobile station while that station is roaming if it is determined during the data examination that the OriginationRequest Invocation should be employed to provide access to the voice mail system for the mobile station.

11. The method of claim 10 further comprising the step of:

sending the mobile station'"'"'s voice message center routing information to the MSC in a return result from the HLR.

12. The method of claim 11 further comprising the step of:

the MSC connecting the mobile station to its associated voice message center using the sent routing information.
