## Abstract

A user device that communicates with a network apparatus and in which at least one application is installed. The user device includes a receiver that receives, from the network apparatus, restriction information including a destination identifier for identifying an external network connected to the network apparatus and a barring rate associated with the destination identifier, and a controller that when communication is to be started by the application, controls whether to allow or prevent the communication by the application based on the restriction information.

## Claims

### Claim 1

A user device comprising:
a memory that stores an application that communicates with an external network connected to a network apparatus;
a receiver that receives, from the network apparatus, restriction information including a first destination identifier that identifies the external network and a barring rate associated with the first destination identifier;
a controller; and
a connection requester that sends a connection request signal to the controller in response to receiving a report to start communication from the application;
wherein the controller that detects that the communication is to be started by the application and determines whether to allow or prevent the communication by the application based on the restriction information.

### Claim 2 (depends on 1)

The user device as claimed in claim 1, wherein
the connection request signal includes a second destination identifier that identifies an external network with which the application is to start the communication; and
the controller compares the second destination identifier with the first destination identifier to control whether to allow or prevent the communication by the application.

### Claim 3 (depends on 2)

The user device as claimed in claim 2, wherein the connection request signal is a signal that requests establishment of a radio layer connection between the user device and the network apparatus.

### Claim 4 (depends on 2)

The user device as claimed in claim 2,
wherein the connection requester identifies the first destination identifier, based on one of information for managing the first destination identifier and a report from the application.

### Claim 5 (depends on 1)

The user device as claimed in claim 1,
wherein the connection requester identifies the first destination identifier, based on one of information for managing the first destination identifier and a report from the application.

### Claim 6 (depends on 1)

The user device as claimed in claim 1, wherein the connection request signal is a signal that requests establishment of a radio layer connection between the user device and the network apparatus.

### Claim 7 (depends on 6)

The user device as claimed in claim 6,
wherein the connection requester identifies the first destination identifier, based on one of information for managing the first destination identifier application.

### Claim 8

A restriction method performed by a user device, the restriction method comprising:
storing, with the user device, an application that communicates with an external network connected to a network apparatus;
receiving, from the network apparatus, restriction information including a destination identifier that identifies the external network and a barring rate associated with the destination identifier; and
detecting communication is to be started by the application based on a connection request signal in response to a report to start communication from the application; and
determining whether to allow or prevent the communication by the application based on the restriction information.
