Abstract
An approach for call failover to a packetized voice session is described. Impending signal failure is detected on a cellular link supporting a cellular call with a user device. A failover procedure is initiated in response to the detection, wherein the failover procedure includes detecting presence of a wireless data connection, and terminating the cellular call and concurrently activating a voice call application to establish a packetized voice session over the wireless data connection with the user device.
Claims20
A method comprising:
- detecting impending signal failure on a cellular link supporting a cellular call with a user device;
- and
- initiating a failover procedure in response to the detection, wherein the failover procedure includes,
- detecting presence of a wireless data connection, and
- terminating the cellular call and concurrently activating a voice call application to establish a packetized voice session over the wireless data connection with the user device.
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code for one or more programs,
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,
- detect impending signal failure on a cellular link supporting a cellular call with a user device;
- and
- initiate a failover procedure in response to the detection, wherein the failover procedure includes,
- detecting presence of a wireless data connection, and
- terminating the cellular call and concurrently activating a voice call application to establish a packetized voice session over the wireless data connection with the user device.
A method comprising:
- establishing a cellular call with a mobile device over a cellular link;
- presenting a notification message indicating initiation of a failover procedure to terminate the cellular call and to establish a packetized voice call;
- and
- invoking a voice call application to establish a packetized voice session with the mobile device.
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code for one or more programs,
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,
- establish a cellular call with a mobile device over a cellular link,
- present a notification message indicating initiation of a failover procedure to terminate the cellular call and to establish a packetized voice call, and
- invoke a voice call application to establish a packetized voice session with the mobile device.
