A user equipment (UE) including one or more processors configured to cause the UE to prepare to reselect to a macro cell responsive to the UE placing an emergency call in a femtocell, wherein preparing to reselect is performed in addition to placing the emergency call.

System and method for supporting emergency services in home cells

Systems and methods for determining that a maximum number of IP sessions have been established are provided. There are instances when the mobile device transmits a request to the wireless network. According to an aspect, in the event that the maximum number of IP sessions is already established for the mobile device, the wireless network transmits a response indicating that the request cannot be fulfilled. The mobile device determines based on the response that the maximum number of IP sessions is already established, which allows the mobile device to determine the maximum number of IP sessions that can be supported so that IP sessions can be managed accordingly.

A method is provided for indicating an IMS (Internet Protocol Multimedia Subsystem) emergency call back to a user equipment and an access network. The method comprises including in a message from a PSAP (Public Safety Answering Point) to the user equipment and the access network an indication that the emergency call back is from the PSAP.

System and method for indicating emergency call back to user equipment

A mobile device configured for communication in both packet and circuit switched domains. The mobile device includes a domain selector. The domain selector is configured, responsive to selection by a user of one of the packet switched and circuit switched domains, to promote mobile device communication via the selected one of the packet switched and circuit switched domains.

System and method of user-directed dynamic domain selection

A method and apparatus for allowing varied functionality between a sending entity and a receiving entity, the method sending a first message from the sending entity to the receiving entity utilizing a first protocol, detecting an indication that the receiving entity did not recognize the first message or that the receiving entity did not fulfill a request in the first message, and sending a second message from the sending entity to the receiving entity utilizing a second protocol.

Method and system for a wireless communication device to adopt varied functionalities based on different communication systems by specific protocol messages

A user equipment (UE) comprising a processor configured to cause the UE to transmit an emergency calls required indicator (ECRI) to a network component responsive to the UE receiving an instruction to place an emergency call; and to receive an emergency calls supported indicator (ECSI) prior to placing an emergency call, wherein a value of the ECSI indicates a type of emergency services supported by a femtocell, where the processor is further configured to cause the UE to transmit the ECRI before receiving the ECSI.

Emergency services in home cells system and method

Methods are provided for transitioning between SIP and MIP. Mobile devices, upon detecting a new system, automatically attempt a MIP session to avoid the default position of SIP. A history is maintained of systems visited, and for systems that did not support MIP in the past, a MIP session is not attempted, but rather SIP is initiated from the start.

System and method for handling simple IP to mobile IP transition

Systems and methods for radio access technology specific routing for multi-mode mobile devices are provided. For each of a number of radio access technologies supported by a mobile device, the mobile device is configured to use respective routing information. This has the advantage of allowing radio access technology specific processing to be performed.

System and method for radio access technology-specific routing for multi-mode mobile devices

Methods, mobile stations and networks are provided that cause a packet data service reconnect to be performed automatically after the occurrence of an event triggering registration, even in some circumstances where such a data service reconnect would not normally occur. This avoids complications that can arise due to the packet data service being discontinued upon registration and the resulting inability to reach the mobile station.

System and method for registration and packet data reconnect

An apparatus and method is provided for making use of black-list network information to make scanning more efficient in multi-mode mobile devices. When performing a scan for a network, if a network that is blacklisted is found, scanning is discontinued for any network that has the same radio access technology as the network that was found. Thus, excessive scanning that can be costly for the mobile device in terms of battery life and responsiveness to provide service, is avoided.

Apparatus and method for performing network scanning using black-list network information

Systems and Method are provided for managing IP sessions based on how many IP sessions are supported. According to an embodiment of the application, the wireless network determines how many IP sessions can be supported for the mobile device residing in a given area such as a routing area, and to transmit to the mobile device an identification of how many IP sessions can be supported. According to another embodiment of the application, the mobile device receives the identification of how many IP sessions can be established, and manages IP sessions based on the identification. Since the mobile device is privy to how many IP sessions can be established, the mobile device is able to properly manage IP sessions.

System and method for managing IP sessions based on how many IP sessions are supported

A method includes measuring an operating parameter of a battery of a mobile device. The measured operating parameter is translated into an equivalent series resistance (ESR) value. The ESR value is adjusted by a correction factor to generate a corrected ESR value. The capacity of the battery is determined based on the corrected ESR value. The correction factor is automatically calibrated based on the measured operating parameter.

System and method of battery capacity estimation

A system and method of notifying a user of events in a customizable manner during and not during a voice call is provided. According to one aspect, the notifications are configurable to be dependant on whether or not there is an active voice call. Notifications may also be configured to be different depending on whether or not the wireless device is inside a device holster. Notifications can be configured to be different for different events so that the user may be able to associate certain notifications with certain events. The user can also configure the type of events that trigger notification. Notifications include any combination of audible cues, visual cues, and vibration cues.

Customizability of event notification on telephony-enabled devices

A method in a mobile device includes receiving an incoming call. An emergency signal, associated with an incoming call, is detected. The emergency signal indicates the incoming call is from an emergency call center. Responsive to detecting the emergency signal, the emergency call is automatically answered, and information identifying the incoming call as an emergency call is displayed on the mobile device.

Apparatus and method of explicit indication of call from emergency call centre

Provided is a system and method of wireless network selection based on service offered. The wireless device scans for available wireless networks upon an event triggering registration. If the wireless device determines based on its SIM that none of the available wireless networks are high priority networks for registration, then the wireless device automatically selects an available wireless network for registration based on, for at least one of the available wireless networks that the wireless device previously registered to, whether CS (Circuit Switched) service was rejected but PS (Packet Switched) service was allowed. Next, the wireless device automatically attempts to register with the selected wireless network. In this manner, the wireless device attempts to register with a wireless network that does not reject CS service while allowing PS service. If the wireless device nonetheless registers with such a wireless network, then registration can be reattempted with another available wireless network.
