Abstract

An improved method and system for handling a call from a mobile station within a wireless communication network is disclosed. The mobile telephone communication network includes a mobile switching center (MSC) and a service control point (SCP). After a call has been initiated from a first mobile station to a second mobile station, the MSC sends an initialDP message to the SCP. The initialDP message preferably includes a classmark field. In response to the call from the first mobile station to the second mobile station, the MSC sets up the call to the second mobile station. The MSC then notifies the SCP that the call to the second mobile station has been initiated. Finally, the MSC receives a request from the SCP to inform the SCP when the call being answered by the second mobile station.

Claims

1. A method for handling calls within a mobile telephone communication network, wherein said mobile telephone communication network includes a mobile switching center (MSC) and a service control point (SCP), said method comprising:

in response to a call from a first mobile station to a second mobile station, building an initialDP message having a classmark field, wherein said classmark field indicates capabilities of said first mobile station;

sending said initialDP message by said MSC to said SCP;

in response to said initialDP message from said MSC, said SCP continues a dialog with said MSC using standard protocol messages; and

upon completion of said dialog, said MSC initiates said call to said second mobile station.

2. The method of claim 1, wherein said building further includes building an initialDP message by said MSC.

3. The method of claim 1, wherein said classmark field describes encryption capabilities, radio-frequency (RF) power level supported, and/or short message capability of said first mobile station.

4. A mobile telephone communication network having a mobile switching center (MSC) and a service control point (SCP), said mobile telephone communication network comprising:

means for building an initialDP message having a classmark field, wherein said classmark field indicates capabilities of said first mobile station, in response to a call from a first mobile station to a second mobile station;

means for sending said initialDP message from said MSC to said SCP;

means for continuing a dialog with said MSC using standard protocol messages, in response to said initialDP message from said MSC; and

means for initiating said call to said second mobile station, upon completion of said dialog.

5. The mobile telephone communication network of claim 4, wherein said building means further includes building an initialDP message by said MSC.

6. The mobile telephone communication network of claim 4, wherein said classmark field describes encryption capabilities, radio-frequency (RF) power level supported, and/or short message capability of said second mobile station.
