A device receives, from an emergency call server (ECS), a query that includes a telephone number, a femto global positioning system (GPS) identifier, and an Internet protocol (IP) address associated with a user equipment (UE) placing an emergency call. The device obtains a serving cell E-UTRAN cell global identifier (ECGI) of the UE based on the query, and determines whether the ECGI is a macro ECGI associated with a base station or a femto ECGI associated with a femto cell.

Emergency support for voice over internet protocol (VoIP) over mixed macro and femto networks

In existing standards for packet data communication over enhanced cellular networks, for a subscriber having a static address, the network relies on the terminal to provide the static address. Consequently, the terminal needs to know (be programmed with) its own static address and typically the address of a home agent element of the network. To eliminate the attendant need to provision such address data in the mobile station, the static address is stored in a node of the network, and the network assigns that one address to the mobile station, every time when the subscriber requests packet data service, for example, using a mobile IP (MIP) type address assignment procedure. The address assignment operation may also provide the home agent address to the station.

Network based IP address assignment for static IP subscriber

Improved billing accuracy in session-based communications is provided by separating session (or connection) billing from session processing. If two sessions () on the same serving node are bridged, so the true stop time of the prior session () is not known, the stop time of the prior session is defined as a function of the last activity during (TALS) that session. To accomplish this, the serving node detects and stores the time of last activity and the time of initiation for each connection and determines the billing time accordingly, regardless of the state of the inactivity timer () or whether sessions were bridged by the serving node.
