Abstract

A communication system, a method for extending stand-by time, and a computer readable medium therefor are provided. The communication system includes a mobile communication apparatus and a core network. The method and the computer readable medium therefor perform the following steps. When the mobile communication apparatus is in a low battery situation or required to enter a power saving mode by a user, it sends a signal to the core network to request to enter the power saving mode. After receiving the signal, the core network reduces a data quantity transmitted to the mobile communication apparatus, and thereby the purpose of extending stand-by time is achieved.

Claims

1. A communication system for extending stand-by time, comprising:

a mobile communication apparatus for transmitting a signal for entering a power saving mode; and

a core network for reducing a data quantity transmitted to the mobile communication apparatus in response to the signal.

2. The communication system as claimed in claim 1, wherein the mobile communication apparatus transmits the signal when a battery power of the mobile communication apparatus is lower than a threshold value.

3. The communication system as claimed in claim 1, wherein the mobile communication apparatus transmits the signal in response to a user'"'"'s request of entering the power saving mode manually.

4. The communication system as claimed in claim 1, wherein the core network reduces the data quantity transmitted to the mobile communication apparatus according to a configuration which is one of a data source, a data type, a file size, a data content, a data configuration, and an environmental parameter.

5. The communication system as claimed in claim 4, wherein the core network decides one of sending the data quantity automatically and being accessed by a user manually according to the data type.

6. The communication system as claimed in claim 1, wherein the mobile communication apparatus comprises a cellular phone.

7. A core network, used in a communication system, wherein the communication system comprises a mobile communication apparatus, the core network storing a computer program, which reduces a data quantity transmitted to the mobile communication apparatus in response to a signal, requested by the mobile communication apparatus, for entering a power saving mode.

8. The core network as claimed in claim 7, wherein the computer program reduces the data quantity transmitted to the mobile communication apparatus according to a configuration which is one of a data source, a data type, a file size, a data content, a data configuration, and an environmental parameter.

9. The core network as claimed in claim 8, wherein the core network decides one of sending the data quantity automatically and being accessed by a user manually according to the data type.
