## Abstract

A mobile communication system comprises a user equipment configured to perform a radio communication with a mobile communication network, a plurality of nodes including a proxy target node provided on the mobile communication network and configured to execute a proxy process of executing a calculation process of an application used by the user equipment on behalf of the user equipment. The switching information used for a switching process switching the proxy target node from a first node to a second node is notified to at least one of the first node, the second node, and the user equipment.

## Claims

### Claim 1

A mobile communication system comprising:
a user equipment configured to perform a radio communication with a mobile communication network;
a plurality of nodes including a proxy target node provided on the mobile communication network and configured to execute a proxy process of executing a calculation process of an application used by the user equipment on behalf of the user equipment; and
a notificator configured to notify at least one of a first node, a second node, and the user equipment of switching information used for a switching process of switching the proxy target node from the first node to the second node.

### Claim 2 (depends on 1)

The mobile communication system according to claim 1, wherein
the first node includes the notificator,
the switching information includes at least one of information indicating a processing load of the proxy process in the first node and information indicating the application, and
the notificator is configured to notify the second node of the switching information.

### Claim 3 (depends on 1)

The mobile communication system according to claim 1, further comprising
a management apparatus configured to manage the plurality of nodes, wherein
the first node includes the notificator,
the switching information includes information indicating a communication path to the management apparatus, and
the notificator is configured to notify the second node of the switching information.

### Claim 4 (depends on 1)

The mobile communication system according to claim 1, wherein
the second node includes the notificator,
the switching information includes at least one of information indicating a processing capability of the second node for the proxy process and information indicating a processing load in the second node, and
the notificator is configured to notify the first node of the switching information.

### Claim 5 (depends on 1)

The mobile communication system according to claim 1, further comprising
a management apparatus configured to manage the plurality of nodes, wherein
the management apparatus includes the notificator,
the switching information includes information indicating an area formed by one or a plurality of nodes having a capability to execute the proxy process, and
the notificator is configured to notify the first node or the user equipment of the switching information.

### Claim 6

An apparatus used in a mobile communication system including a user equipment configured to perform a radio communication with a mobile communication network and a plurality of nodes including a proxy target node provided on the mobile communication network and configured to execute a proxy process of executing a calculation process of an application used by the user equipment on behalf of the user equipment, the apparatus comprising
a notificator configured to notify at least one of a first node, a second node, and the user equipment of switching information used for a switching process for switching the proxy target node from the first node to the second node.

### Claim 7

A mobile communication system comprising:
a user equipment configured to perform a radio communication with a mobile communication network;
a proxy target node provided on the mobile communication network and configured to execute a proxy process of executing a calculation process of an application used by the user equipment on behalf of the user equipment; and
a notificator configured to notify at least one of the proxy target node and the user equipment of selection information used for selecting whether the calculation process is executed by the user equipment or the proxy process is executed by the proxy target node.

### Claim 8 (depends on 7)

The mobile communication system according to claim 7, further comprising
a base station provided on the mobile communication network, wherein
the proxy target node is an apparatus different from the base station, and
the selection information includes information indicating a characteristic of a communication channel between the base station and the proxy target node.

### Claim 9 (depends on 7)

The mobile communication system according to claim 7, wherein the selection information includes information indicating a processing load of the calculation process.
