Abstract

A system and method in a radio telecommunications network for automatically conveying a Wireless Office System (WOS) frequency set to a mobile station (MS) belonging to the WOS. The network includes a public cell, and a private WOS located within the public cell. A WOS controller sends the WOS frequency set from the WOS to an Equipment Identity Register (EIR) in the network whenever the WOS changes its frequency set. When the MS registers in the public cell in which the WOS is located, a mobile switching center (MSC) serving the public cell notifies an Intelligent Roaming Database (IRDB) of the registration. The IRDB fetches the WOS frequency set from the database, and obtains location information for the MS from a home location register (HLR). The IRDB then sends the WOS frequency set to the MS in an IS-136 R-DATA message.

Claims

1. In a radio telecommunications network having a public cell, and a private Wireless Office System (WOS) located within the public cell, a method of automatically conveying a WOS frequency set to a mobile station (MS) belonging to the WOS, said method comprising the steps of:

determining the WOS frequency set in the WOS;

sending the WOS frequency set from the WOS to an enhanced Equipment Identity Register (EIR) in the network;

determining in a mobile switching center (MSC) serving the public cell whether the MS registered in the public cell in which the WOS is located;

notifying by the MSC, an Intelligent Roaming Database (IRDB) that the MS has registered in the public cell;

fetching by the IRDB, the WOS frequency set from the EIR, upon determining that the MS registered in the public cell in which the WOS is located; and

sending the WOS frequency set to the MS.

2. The method of automatically conveying a WOS frequency set to a MS of claim 1 wherein the step of sending the WOS frequency set from the WOS to an EIR in the network includes sending the WOS frequency set to the EIR whenever the WOS changes its frequency set.

3. The method of automatically conveying a WOS frequency set to a MS of claim 1 wherein the step of sending the WOS frequency set from the WOS to an EIR in the network includes sending the WOS frequency set over an Internet connection to the EIR.

4. The method of automatically conveying a WOS frequency set to a MS of claim 1 wherein the step of sending the WOS frequency set to the MS includes sending the WOS frequency set to the MS in an IS-136 R-DATA message.

5. The method of automatically conveying a WOS frequency set to a MS of claim 4 wherein the step of sending the WOS frequency set to the MS also includes obtaining location information for the MS from a home location register (HLR) in the network.

6. In a radio telecommunications network having a public cell, a mobile switching center (MSC) serving the public cell, and a private Wireless Office System (WOS) located within the public cell, a method of automatically conveying a WOS frequency set to a mobile station (MS) belonging to the WOS, said method comprising the steps of:

sending the WOS frequency set over an Internet connection from the WOS to an Equipment Identity Register (EIR) in the network whenever the WOS changes its frequency set;

determining that the MS registered in the public cell in which the WOS is located;

notifying by the MSC, an Intelligent Roaming Database (IRDB) that the MS has registered in the public cell;

fetching by the IRDB, the WOS frequency set from the EIR; and

obtaining location information for the MS from a home location register (LHR) in the network; and

sending the WOS frequency set to the MS in an IS-136 R-DATA message.

7. In a radio telecommunications network having a public cell, and a private Wireless Office System (WOS) located within the public cell, a system for automatically conveying a WOS frequency set to a mobile station (MS) belonging to the WOS, said system comprising:

means within the WOS for changing the WOS frequency set in response to changing radio conditions;

an enhanced Equipment Identity Register (EIR) in the network that stores the WOS frequency set;

a WOS controller that sends the WOS frequency set from the WOS to the EIR whenever the WOS changes its frequency set;

a mobile switching center (MSC) serving the public cell that determines that the MS registered in the public cell in which the WOS is located;

an Intelligent Roaming Database (IRDB) that fetches the WOS frequency set from the EIR when the IRDB is notified by the MSC that the MS registered in the public cell in which the WOS is located; and

means for sending the WOS frequency set to the MS.

8. The system for automatically conveying a WOS frequency set to a MS of claim 7 further comprising an Internet connection between the WOS controller and the EIR.

9. The system for automatically conveying a WOS frequency set to a MS of claim 7 wherein the means for sending the WOS frequency set to the MS includes means for sending an IS-136 R-DATA message from the IRDB to the MS, the R-DATA message including the WOS frequency set.
