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).
