摘要:
In one aspect of the instant invention, a method is provided for controlling roaming in a communications system. The method comprises storing a 15-digit MIN-based-IMSI in the mobile device. The 15-digit MIN-based-IMSI is comprised of a 10-digit Mobile Identification Number (MIN) and a 15-digit Home Network Identifier (HNI). Generally, the communications system uses the 15-digit MIN-based-IMSI to control roaming. However, the mobile device transmits only the 10-digit MIN in response to the mobile device being within a home network. To form the 15-digit universal identifier, the home network appends its HNI to the received MIN. When the mobile device is outside of its home network, the mobile device transmits the entire 15-digit universal identifier.

A method is provided for controllably migrating a wireless network from MIN based operation to IMSI based operation. The method comprises implementing changes that affect inter-network operations during a first phase of the migration. Remaining changes, including changes that affect intra-network operations are implemented during a second phase of the migration.

A method of communication to at least one wireless unit originating an emergency call. The method includes the step of receiving at least one tag identifier in response to the emergency call originating from the at least one wireless unit. Once the tag identifier is received, a wireless call back number corresponding with the at least one tag identifier may be transmitted. A public service answering point emergency call register (“PSAP-ECR”) may receive the at least one tag identifier and transmits the wireless call back number over a D interface.

An emergency routing number is assigned to each switch in a wireless network. When a switch of the wireless network routes an emergency call to a Public Service Answering Point (PSAP), the switch sends the emergency routing number as the calling party number and provides the PSAP with the identifier of the mobile station. If the emergency call drops, the PSAP performs a call back using the emergency routing number as the called party number. The switch that routed the emergency call from the mobile station to the PSAP receives the call back. The PSAP also sends the identifier of the mobile station to the switch. When a switch receives its emergency routing number as the called party number, the switch recognizes an emergency call back situation and pages the mobile station identified by the mobile station identifier received in association with the emergency routing number. The mobile station is then reconnected with the PSAP.

A system and method are provided for managing emergency services received by a mobile terminal having a temporary wireless directory number (TDN). The system includes an emergency call register (ECR) network and a disaster recovery call center (DRCC). The DRCC authorizes the mobile terminal to receive emergency services and provides service information for managing the emergency services to the ECR network if the mobile terminal is authorized to receive the emergency services.

A system is provided to allow a network to obtain the location of a mobile station (e.g. mobile phone) having AGPS/AFLT CDMA capability during an emergency call—without the use of the MPCAP parameter. The MPC invokes the PDE, which is IS-801 AGPS capable, without the MPCAP parameter. The PDE then queries the mobile for its geolocation capabilities, in the absence of the MPCAP parameter. This allows a visited network (e.g. the network in which the mobile station is roaming) to obtain a position (based on IS-801 AGPS/AFLT) for roaming mobile stations that are CDMA AGPS/AFLT capable—without the use of the network MPCAP parameter.

In one aspect of the instant invention, a method is provided for controlling international roaming in a communications system. The method comprises storing a 15-digit universal identifier in a mobile device in two locations ordinarily used to store a 15-digit MIN-based-IMSI and a 15-digit true IMSI. The universal identifier is comprised of a 10-digit Mobile Identification Number (MIN) and a 5-digit Home Network Identifier (HNI), which is comprised of a 3-digit Mobile Country Code (MCC) and a 2-digit Mobile Network Code (MNC). Generally, the communications system uses the universal identifier to control international roaming. However, the mobile device transmits only the 10-digit MIN in response to the mobile device being within a home network. To form the 15-digit universal identifier, the home network appends its HNI to the received MIN. When the mobile device is outside of its home network, the mobile device transmits the entire 15-digit universal identifier.

A method is provided for routing an emergency call. The method comprises receiving an emergency call and identifying an end node associated with the call. The end node may be a communications device involved in establishing the emergency call that is geographically near the originator of the emergency call. A look-up table is then accessed to identify the appropriate public safety answering point (PSAP) associated with the end node, and the emergency call is routed to the identified PSAP.
