You have to follow this http://docs.ionic.io/services/push/, to generate all the keys and Ids necessary.

Then in your *.ts code:

At the startup of the app you have to register the token of each user and save it on custom db (the example call a php Page http:///indexToken.php):

registerToken(){
    this.push.register().then((t: PushToken) => {
      return this.push.saveToken(t);
    }).then((t: PushToken) => {
      //salvo a db il token
      let variables = 'pushtoken=' + t.token + '&name=' +  this.username;
      let headers = new Headers();
      let serveraddress = 'http://<yourwww>/indexToken.php';
      //content-type
      headers.append('Content-Type', 'application/x-www-form-urlencoded;charset=utf-8');

      /**************************************/
      // don't have the data yet
      new Promise(resolve => {
        this.http.post(serveraddress,variables,{headers:headers})
          .map(
            res => res.json()
          )
          .subscribe(data => {
              alert('Token saved DB: ' + data['ret']);
            },
            err =>{
              alert('error token DB: ' + err);
            });
      });

      alert('Token saved: '+ t.token);
    });
}

Then you can retrieve the tokens of the users from db, I use an auxiliar User class. Then you should be able to send push notification, setting the specific user token in the call.

export class User {
  id: string;
  name:string;
  pushtoken:string;
  constructor(name: string,pushtoken:string) {
    this.pushtoken = pushtoken;
    this.name = name;
  }
}


 sendPushByPhone(event, user) {
    var token = user.pushtoken;
    //PROFILE_TAG The Security Profile tag found in Settings › Certificates in the Dashboard
   // my profile tag is named "prod"
    let body: any = {
      "tokens": [token],
      "send_to_all": false,
      "profile": "prod",
      "notification": {
        "message": "Test From App"
      }
    }

    //generate apitoken https://docs.ionic.io/api/http.html
    var apitoken = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
    var headers = new Headers();
    headers.append('Content-Type', 'application/json');
    headers.append('Authorization','Bearer ' + apitoken);
    return this.http.post("https://api.ionic.io/push/notifications"
      , body, { headers: headers })
      .map((response) => response)
      .subscribe(data => {
        },
        err =>{
          alert('error token DB: ' + err);
        }
      )
  }
