Legacy mobile station support on sip-based FEMTO device
First Claim
1. For use in a wireless communications network, a Femto Access Point (FAP) capable of communicating messages via an internet protocol, said FAP comprising:
- a modified XML schema configured to include subscriber station identification information in a Presence Information Data Format Location (PIDF-LO) signal, wherein said FAP is configured to transmit the PIDF-LO via session initiation protocol to a mobile switching center (MSC) Femto Interworking Function (MFIF), wherein the PIDF-LO signal is configured to be interpreted by an XML schema of the MFIF to extract the subscriber station identification information, the MFIF configured to send the messages and the subscriber station information to a MSC.

Abstract
A Femto network capable of relaying wireless communications is provided. The Femto network includes a Femto Access Point (FAP) and an MSC Femto Interworking Function (MFIF). The FAP and the MFIF each include a modified XML schema. The FAP modified XML schema is configured to include subscriber station identification information in a Presence Information Data Format Location (PIDF-LO) signal. The FAP is configured to transmit said the PIDF-LO via session initiation protocol. The MFIF XML schema is configured to interpret the PIDF-LO signal and extract the subscriber station identification information from said PIDF-LO signal. The MFIF is configured to send said messages and said subscriber station information to a mobile switching center (MSC).

16. For use in a Femto network capable of relaying wireless messages, a method of communicating messages via an internet protocol, the method comprising:
-
transmitting, at a Femto Access Point (FAP), a Presence Information Data Format Location (PIDF-LO) signal via session initiation protocol, the FAP comprising a first modified XML schema configured to include subscriber station identification information in the PIDF-LO signal; receiving, at a mobile switching center (MSC) Femto Interworking Function (MFIF), the PIDF-LO signal via the session initiation protocol from the FAP; using, at the MFIF, a second XML schema to extract the subscriber station identification information from the PIDF-LO signal; and sending the messages and the subscriber station identification information to a mobile switching center. - View Dependent Claims (17, 18, 19, 20)
