Abstract

A system and method of updating radio network data in a plurality of devices deployed in Base Stations (BSs) in a radio telecommunications network. Each BS is interfaced with a Mobile Switching Center (MSC) through an Internet Protocol (IP) packet data network. Device update data is sent in an IP message from the MSC to the BS where the plurality of devices are simultaneously updated. Device updates can be performed at the cell level, the location area level, or the exchange level. In one embodiment, the BS joins a multicast group, and the device update data is sent in an IP multicast message. In another embodiment, the BSs monitor predefined User Datagram Protocol (UDP) ports for particular types of device update data, and the device update data is sent in an IP broadcast message.

Claims

1. A method of updating radio network data in a plurality of devices deployed within a Base Station (BS), the BS being located in a radio telecommunications network, said method comprising the steps of:

interfacing the BS with a Mobile Switching Center (MSC) through an Internet Protocol (IP) packet data network;

assigning the BS an IP address valid on the IP packet data network;

sending device update data from the MSC to the BS in an IP message with the IP address over the IP packet data network;

receiving the IP message at the BS from the MSC; and

updating at least one of the plurality of devices by the BS using the device update data from the IP message wherein the at least one of the plurality of devices is identified by means of the IP message.

2. The method of updating radio network data of claim 1 wherein the step of sending device update data from the MSC to the BS in an IP message includes sending the device update data in an IP multicast message, and the method further comprises, prior to assigning the BS an IP address, the step of joining the BS in a multicast group.

3. The method of updating radio network data of claim 2 wherein the step of sending device update data from the MSC to the BS in an IP message includes sending the device data to a multicast group address that comprises a multicast group designation, a device data type for the device update data, and a Base Station Identification (BSID).

4. The method of updating radio network data of claim 2 wherein the step of joining the BS in a multicast group includes the step of joining the BS in a plurality of multicast groups, each of said multicast groups receiving a different type of device update data.

5. The method of updating radio network data of claim 4 wherein the step of joining the BS in a plurality of multicast groups includes the steps of:

joining the BS in a first multicast group that receives device update data for Digital Control Channels (DCCHs); and

joining the BS in a second multicast group that receives device update data for Digital Traffic Channels (DTCs).

6. The method of updating radio network data of claim 1 further comprising, before the step of updating at least one of the plurality of devices by the BS, the step of determining whether the devices are to be updated immediately or at a specified time.

7. The method of updating radio network data of claim 1 wherein the step of updating at least one of the plurality of devices by the BS includes the steps of:

identifying which ones of the plurality of devices in the BS the device update is directed to; and

updating the identified plurality of devices.

8. The method of updating radio network data of claim 1 further comprising the step of assigning the BS to monitor a User Datagram Protocol (UDP) port for device update data.

9. The method of updating radio network data of claim 1 wherein the step of assigning the BS an IP address further comprises assigning each of the devices deployed within the BS an IP address and wherein the step of sending device update data from the MSC to the BS in an IP message with the IP address further includes sending the device update data in the IP message with the IP address to each of the plurality of devices over the IP packet data network.

10. An Internet Protocol (IP) Base Station (BS) in a radio telecommunications network, said BS comprising:

a plurality of radio network devices deployed therewithin;

a signaling mechanism for receiving IP messages containing an IP address assigned to the BSC and containing device update data from a Mobile Switching Center (MSC) through an IP packet data network; and

means within the BS for updating at least one of the plurality of devices with the device update data wherein the at least one of the plurality of devices is identified by means of the IP messages.

11. The IP Base Station of claim 10 wherein the signaling mechanism receives IP multicast messages that contain device update data.

12. The IP Base Station of claim 10 wherein the signaling mechanism includes at least one User Datagram Protocol (UDP) port for monitoring IP broadcast messages containing device update data.
