## Abstract

A communication apparatus includes a display; an application processor that is configured to control update of the display; and a modem processor that is configured to control a modem, wherein the modem processor is further configured to control the update of the display in place of the application processor.

## Claims

### Claim 1

A communication apparatus comprising:
a display;
an application processor that is configured to control update of the display; and
a modem processor that is configured to control a modem,
wherein the modem processor is further configured to control the update of the display in place of the application processor.

### Claim 2 (depends on 1)

The communication apparatus according to claim 1, wherein the modem processor is further configured to control the update of the display in place of the application processor when a predetermined condition is satisfied.

### Claim 3 (depends on 1)

The communication apparatus according to claim 1, wherein the modem processor synchronizes a timing of the update of the display with a timing of reception of the modem.

### Claim 4

A method for controlling a communication apparatus including a display, an application processor that is configured to control update of the display, and a modem processor that is configured to control a modem, wherein the modem processor controls the update of the display in place of the application processor.
