US 9,426,642 B1 · Systems and methods facilitating communication with respect to a plurality of communication networks using pullback techniques

Abstract

A mobile device may establish and register a connection to a first network at a registration server, and may subsequently establish and register a connection to a second network at the registration server. Registration of the connection to the second network may designate the second network as a primary network for providing services to the mobile device. In response to the registration of the connection to the second network, the mobile device may receive a notification indicating the connection to the second network is designated as a primary connection for providing at least one service to the mobile device. In response to receiving the notification, the mobile device may transmit, to a network entity, a pullback message including a request to refresh the registration of the first network at the registration server, thereby designating the first network as the primary network for providing the services to the mobile device.

Claims36

Dependent claims

A method comprising:

establishing, by a mobile device, a connection to a first network;
establishing, by the mobile device, a connection to a second network;
receiving, by the mobile device, a notification in response to establishing the connection to the second network, wherein the notification indicates that the connection to the second network has been designated as a primary connection for providing at least one service to the mobile device;
and
transmitting, by the mobile device, a pullback message to a network entity, wherein the pullback message includes a request to refresh a registration of the connection between the mobile device and the first network at a registration server, and wherein the refreshing of the registration causes the connection between the mobile device and the first network to be designated as the primary connection for providing the at least one service to the mobile device.

2 more elements

An apparatus comprising:

a memory;
and
a processor coupled to the memory, the processor configured to perform operations comprising:
establishing a connection between a mobile device to a first network;
establishing a connection between the mobile device and a second network;
receiving a notification in response to establishing the connection to the second network, wherein the notification indicates that the connection to the second network has been designated as a primary connection for providing at least one service to the mobile device;
and
transmitting a pullback message to a network entity, wherein the pullback message includes a request to designate the connection between the mobile device and the first network as the primary connection for providing the at least one service to the mobile device, wherein the designation is caused by refreshing, at a registration server, a registration of the connection between the mobile device and the first network.

5 more elements

A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to perform operations comprising:

establishing a connection between a mobile device to a first network;
establishing a connection between the mobile device and a second network;
receiving a pullback message in response to establishing the connection to the second network, wherein the pullback message indicates that the connection to the second network has been designated as a primary connection for providing at least one service to the mobile device;
and
transmitting a pullback message to a network entity, wherein the pullback message includes a request to designate the connection to between the mobile device and the first network as the primary connection for providing the at least one service to the mobile device, wherein the designation is caused by refreshing, at a registration server, a registration of the connection between the mobile device and the first network.

2 more elements

A method comprising:

receiving, by a multimedia communication server (MMCS), a request to register a connection between a mobile device and a first network;
in response to receiving the request, registering, by the MMCS, the connection between the mobile device and the first network at a registration server of a second network;
receiving, by the MMCS, a first notification indicating that the mobile device has been registered with the second network at the registration server, wherein, at the registration server, a connection between the mobile device and the second network is designated as a primary connection for providing at least one service to the mobile device;
in response to receiving the first notification, transmitting a second notification to the mobile device, wherein the second notification indicates that the connection between the mobile device and the second network is designated as the primary connection for providing the at least one service to the mobile device;
and
in response to receiving a pullback message from the mobile device, refreshing, by the MMCS, the registration of the connection between the mobile device and the first network at the registration server, wherein refreshing the registration causes the connection between the first network and the mobile device to be designated as the primary connection for providing the at least one service to the mobile device.

3 more elements

An apparatus comprising:

a memory;
and
a processor coupled to the memory, the processor configured to perform operations comprising:
receiving a request to register a connection between a mobile device and a first network;
in response to receiving the request, registering the connection between the mobile device and the first network at a registration server of a second network;
receiving a first notification indicating that the mobile device has been registered with the second network at the registration server, wherein, at the registration server, a connection between the mobile device and the second network is designated as a primary connection for providing at least one service to the mobile device;
in response to receiving the first notification, transmitting a second notification to the mobile device, wherein the second notification indicates that the connection between the mobile device and the second network is designated as the primary connection for providing the at least one service to the mobile device;
and
in response to receiving a pullback message from the mobile device, refreshing the registration of the connection between the mobile device and the first network at the registration server, wherein refreshing the registration causes the connection between the first network and the mobile device to be designated as the primary connection for providing the at least one service to the mobile device.

6 more elements

A non-transitory computer readable medium storing instructions that, when executed by a processor, cause the processor to perform operations comprising:

receiving, by a multimedia communication server (MMCS), a request to register a connection between a mobile device and a first network;
in response to receiving the request, registering, by the MMCS, the connection between the mobile device and the first network at a registration server of a second network;
receiving, by the MMCS, a first notification indicating that the mobile device has been registered with the second network at the registration server, wherein, at the registration server, a connection between the mobile device and the second network is designated as a primary connection for providing at least one service to the mobile device;
in response to receiving the first notification, transmitting a second notification to the mobile device, wherein the second notification indicates that the connection between the mobile device and the second network is designated as the primary connection for providing the at least one service to the mobile device;
and
in response to receiving a pullback message from the mobile device, refreshing, by the MMCS, the registration of the connection between the mobile device and the first network at the registration server, wherein refreshing the registration causes the connection between the first network and the mobile device to be designated as the primary connection for providing the at least one service to the mobile device.
