Mobile Terminated IMS Calls on Devices Which Support Wi-Fi and Cellular Radios
First Claim
1. A mobile device, comprising:
- at least one antenna;
a first radio, wherein the first radio is configured to perform cellular communication with a cellular base station using at least one cellular radio access technology (RAT);
a second radio, wherein the second radio is configured to perform Wi-Fi communication with a Wi-Fi access point;
at least one processor communicatively coupled to the first and second radios, wherein the mobile device is configured to perform voice and/or data communications;
wherein the mobile device is configured to;
establish communication with a cellular carrier over a Wi-Fi network;
register, with an IMS server, a first IP address associated with the Wi-Fi network communication;
register, with the IMS server, a second IP address associated with the communication with the cellular network;
wherein, upon occurrence of a mobile terminating call received from the cellular carrier, an incoming call notification on the Wi-Fi network is transmitted to the mobile device using the first IP address and an incoming call notification on the cellular network is transmitted to the mobile device using the second IP address;
wherein the mobile device is configured to receive and respond to at least one of the incoming call notifications.

Abstract
Embodiments relate to apparatus, systems, and methods for reception of calls on a mobile device that includes Wi-Fi and cellular radios. The mobile device may be configured to establish communication on a Wi-Fi network with a cellular carrier. The mobile device may further be configured to register a first IP address with an IMS server for the Wi-Fi network communication and register a second IP address with the IMS server for the cellular network communication (or register different ports of a single IP address with Wi-Fi and cellular). Upon occurrence of a mobile terminating call from the cellular carrier, the mobile device may receive an incoming call notification on one or both of the Wi-Fi network using the first IP address and the cellular network using the second IP address.

13. A method for operating a mobile device, the method comprising:
-
establishing communication on a Wi-Fi network with a cellular carrier; acquiring first destination information from a first packet gateway, wherein the first destination information is useable for receiving Wi-Fi communication; registering the first destination information with an IMS server for receiving Wi-Fi communication; acquiring second destination information from a cellular network packet gateway, wherein the second destination information is useable for receiving cellular communication; registering the second destination information with the IMS server for receiving cellular communication; wherein, upon occurrence of a mobile terminating call received from the cellular carrier, an incoming call notification on the Wi-Fi network is transmitted to the mobile device using the first destination information and an incoming call notification on the cellular network is transmitted to the mobile device using the second destination information; the mobile device receiving and responding to at least one of the incoming call notifications. - View Dependent Claims (14, 15, 16)
