Communication apparatus, communication method, and computer program product

摘要

According to an embodiment, a communication apparatus includes a receiving unit, an obtaining unit, and an analyzing unit. The receiving unit is configured to receive first obtaining method information, which is sent by an information processing unit to a network and which indicates a method of obtaining first data from the network. The obtaining unit is configured to, on behalf of the information processing unit, obtain the first data based on the first obtaining method information received by the receiving unit. The analyzing unit is configured to extract, from the first data obtained by the obtaining unit, second obtaining method information that indicates a method of obtaining second data which needs to be obtained along with obtaining the first data. The obtaining unit also obtains the second data based on the second obtaining method information.

主权项

1. A communication apparatus comprising:
a communication interface to at least: receive first obtaining method information sent by an information processing unit which changes to a low power consumption state after the first obtaining method information is sent, the first obtaining method information being sent to a network and indicating a method of obtaining first data from the network; on behalf of the information processing unit, obtain the first data based on the received first obtaining method information; and extract, from the obtained first data, second obtaining method information that indicates a method of obtaining second data which needs to be obtained, wherein the communication interface also obtains the second data based on the second obtaining method information; and the communication interface changes an operating state of the information processing unit from the low power consumption state to a normal operating state when the obtaining of the first data on behalf of the information processing unit is determined to be completed based on a result of the extracting, the information processing unit not changing from the low power consumption state to the normal operating state at a predetermined timing after the first obtaining method information is sent.
