You can set a cellular network as a preferred route for Internet connections with specified domains.

This feature is supported in mobile applications only.

The main features of the Network Bearer Selection API include:

  • Requesting a route

    You can request a preferred network for the Internet connection with a specified domain.

    The request implements a routing policy for Internet connections from the application that demanded them, as well as from other programs.

  • Releasing a route

    You can cancel the preference for a particular network for the Internet connection with a specified domain.

    The routing policy can be terminated any time. All rules requested by the application are terminated at the end of the application life-cycle.

Prerequisites

To use the Network Bearer Selection API, the application has to request permission by adding the following privileges to the config.xml file:

<tizen:privilege name="http://tizen.org/privilege/internet"/>
<tizen:privilege name="http://tizen.org/privilege/networkbearerselection"/>

Requesting a Route

To request a preferred route for Internet connection with the "www.tizen.org" host:

  1. Define the needed callbacks:

    var statuscb = {
        onsuccess: function() {
            console.log('Routing policy requested');
        },
        ondisconnected: function() {
            console.log('Disconnected');
        }
    };
    
    function onerror(error) {
        console.log(error.code + ' error occurred: ' + error.message);
    }
    
  2. To request a routing policy, use the requestRouteToHost() method of the NetworkBearerSelection interface:
    tizen.networkbearerselection.requestRouteToHost('CELLULAR', 'www.tizen.org', statuscb, onerror);
    

Releasing a Route

To cancel the routing policy for the connection with the "www.tizen.org" host:

  1. Define the needed callbacks:

    function onsuccess() {
        console.log('Routing policy cancelled');
    }
    
    function onerror(error) {
        console.log(error.code + ' error occurred: ' + error.message);
    }
    
  2. To terminate the policy, use the releaseRouteToHost() method of the NetworkBearerSelection interface:
    tizen.networkbearerselection.releaseRouteToHost('CELLULAR', 'www.tizen.org', onsuccess, onerror);
