Over the air provisioning of a wireless mobile station using IP multimedia subsystem mode
First Claim
Patent Images
1. A method implemented by communication infrastructure equipment for provisioning a wireless mobile station, MS, comprising the steps of:
- receiving first signals at an over the air function, OTAF, server, including a request for an update of shared secret data, SSD, of the MS where the first signals use a different signaling protocol other than Internet Protocol Multimedia Subsystem, IMS, signaling, the different signaling protocol being understood by a mobile switching center, MSC, and home location register, HLR;
converting the first signals, including the SSD update request, into corresponding second signals utilizing IMS signaling protocol;
transmitting the second signals to the MS;
receiving third signals from the MS generated in response to the receipt of the second signals, the third signals having the same signaling protocol as the second signals;
converting the third signals into fourth protocol signals having the same signaling protocol as the first signals and transmitting the fourth signals from the OTAF server to the HLR, whereby the MS using only IMS protocol can obtain provisioning from the communication infrastructure equipment that does not utilize IMS signaling among at least some of its nodes.

12. An apparatus incorporated in communication infrastructure equipment for provisioning a wireless mobile station, MS, comprising:
-
an over the air function, OTAF, server adapted to receive first signals that include a request for an update of shared secret data, SSD, of the MS where the first signals use a different signaling protocol other than Internet Protocol Multimedia Subsystem, IMS, signaling, the different signaling protocol being understood by a mobile switching center, MSC, and home location register, HLR;
the OTAF server adapted to convert the first signals, including the SSD update request, into corresponding second signals utilizing IMS signaling protocol and transmit the second signals via a Serving Call Session Control Function, S-CSCF, node to the MS;
the OTAF server adapted to receive third signals from the MS via the S-CSCF node, the third signals generated in response to the receipt of the second signals, the third signals having the same signaling protocol as the second signals;
the OTAF server adapted to convert the third signals into fourth protocol signals having the same signaling protocol as the first signals and transmit the fourth signals to the HLR, whereby the MS using only IMS protocol can obtain over the air provisioning. - View Dependent Claims (13, 14, 15)
