Continuous communication routing for user device applications

A computer-implemented method, comprising:

• receiving a request from an application on a user device to establish a communication session with an IP Multimedia Subsystem (IMS) core of a wireless carrier network for routing communication traffic to the IMS core;
• determining, via a connection manager on the user device, an application priority level indicated by an APN parameter of the application;
• in response to a determination that the APN parameter designates a first priority level, routing, via the connection manager, the communication traffic via a first communication session that seamlessly switches between a continuous link APN bearer on a radio access network of the wireless carrier network and a continuous link APN tunnel on a remote network that connects to a wireless carrier network without interrupting the communication session;
• and
• in response to a determination that the APN parameter designates a second priority level, routing, via the connection manager, the communication traffic via a second communication session and a third communication session, in which the second communication session terminates prior to an establishment of the third communication session.

A user device, comprising:

• one or more processors;
• and
• memory having instructions stored therein, the instructions, when executed by the one or more processors, cause the one or more processors to perform acts comprising:
• receiving a request from an application to establish a communication session with an IP Multimedia Subsystem (IMS) core of a wireless carrier network for routing communication traffic to the IMS core;
• determining an access point name (APN) designated by an APN parameter of the OTT application;
• in response to a determination that the APN parameter designates a first APN, routing the communication traffic via a first communication session that seamlessly switches between a dedicated continuous link APN bearer on a radio access network of the wireless carrier network and a dedicated continuous link APN tunnel on a remote network that connects to wireless carrier network without interrupting the communication session;
• and
• in response to a determination that the APN parameter designates a second priority level, routing, via the connection manager, the communication traffic via a second communication session and a third communication session, in which the second communication session terminates prior to an establishment of the third communication session,
• wherein the second communication session is on an over-the-top (OTT) APN bearer of the radio access network, and the third communication session is on a non-APN routed communication connection established on the remote network that connects to an Evolved Packet Data Gateway (ePDG) of the wireless carrier network.
