Abstract:
A system for registering a mobile device located in a network outside a device's home network is described. In some examples, the system receives a message including contents associated with a location of the mobile device, and extracts the contents of the received message. The system matches the extracted contents to one or more rules associated with an adjustment of subscriber data within a registration database for the home network, adjusts the data, and registers the mobile device having the adjusted data.
Abstract:
Systems and methods for a Session Initiation Protocol (SIP) router are described. In one aspect, the SIP router receives a SIP INVITE for an incoming call to a target mobile subscriber. Responsive to receiving the SIP INVITE, the SIP router identifies, via a Send Routing Information for Short Message (SRI/SM) request to a Home Location Register, a first address of a serving switch in a circuit-switched mobile network; a mobile telephony device associated with the target mobile subscriber is currently location-updated on the serving switch. The SIP router maps the first address to a second address for the serving switch; the second address being a SIP address. Using the SIP address, the SIP router sends the received SIP INVITE to a SIP interface of the serving switch. The serving switch being configured to process the received SIP INVITE and the incoming call to the target mobile subscriber.
