Method, device, server, and system for configuring daylight saving time
View Patent ↗The present invention discloses a method, a device, a server, and a system for configuring daylight saving time, belonging to the field of communications. The method includes: receiving, by a CPE, a message carrying a daylight saving time rule parameter; if a daylight saving time enable flag displays that daylight saving time is enabled, extracting, by the CPE, the daylight saving time rule parameter from the message; obtaining the current year of the CPE; and obtaining start time or end time of daylight saving time according to the current year and the daylight saving time rule parameter. The system includes a CPE and a server. The CPE includes a receiving module, an extracting module, a first obtaining module, and a second obtaining module. The server includes a generating module and a sending module. Through the present invention, daylight saving time can be configured in a single attempt and used permanently.
1. A method for configuring when to start using daylight saving time and when to stop using day light saving time in customer premises equipment (CPE), the method comprising:
in the customer premises equipment (CPE) comprising hardware that executes program instructions and a memory having instructions stored therein that instruct the hardware to perform the method:
receiving a message, by the CPE, the message carrying a daylight saving time rule parameter and a daylight saving time enable flag, wherein the daylight saving time rule parameter does not include a current year and is applied to years obtained by the CPE;
determining by the CPE, whether the daylight saving time enable flag indicates that daylight saving time is enabled;
in instances when the daylight saving time flag indicates that daylight saving time is enabled:
extracting, by the CPE, the daylight saving time rule parameter from the message;
obtaining, by the CPE, the current year of the CPE;
determining, by the CPE, a start time or end time of daylight saving time according to the current year obtained from the CPE and the daylight saving time rule parameter received in the message; and
setting the CPE, by the CPE, to start using daylight saving time at the start time of daylight saving time and to stop using daylight saving time at the end of daylight saving time.
2. The method according to claim 1 , wherein the daylight saving time rule parameter comprises: month m, week w, day d, hour H, minute M, and second S; or month m, date D, hour H, minute M, and second S.
3. The method according to claim 2 , further comprising:
if no date complying with the daylight saving time rule parameter exists, obtaining a last day of month m of the current year, and combining the current year, the month m, the obtained last day, the extracted hour H, minute M, and second S into the start time or end time of the daylight saving time.
4. The method according to claim 3 , wherein the daylight saving time rule parameter further comprises an offset.
5. The method according to claim 3 , further comprising:
sending a prompt, when the start time or end time of the daylight saving time of a system arrives.
6. The method according to claim 2 , wherein the daylight saving time rule parameter further comprises an offset.
7. The method according to claim 1 , wherein the daylight saving time rule parameter further comprises an offset.
8. The method according to claim 7 , further comprising:
sending a prompt, when the start time or end time of the daylight saving time of a system arrives.
9. The method according to claim 1 , further comprising:
sending a prompt, when the start time or end time of the daylight saving time of a system arrives.
10. A customer premises equipment CPE, comprising hardware that executes program instructions, and a memory having instructions stored therein that instruct the hardware to:
receive a message carrying a daylight saving time rule parameter wherein the daylight saving time rule parameter does not include a current year and is applied to years obtained by the CPE;
if a daylight saving time enable flag displays that daylight saving time is enabled, extract the daylight saving time rule parameter from the message;
obtain the current year of the CPE; and
obtain start time or end time of daylight saving time according to the current year obtained from the CPE and the daylight saving time rule parameter received in the message.
11. The CPE according to claim 10 , wherein the daylight saving time rule parameter comprises: month m, week w, day d, hour H, minute M, and second S; or month m, date D, hour H, minute M, and second S.
12. The CPE according to claim 11 , further comprising wherein:
if no date complying with the daylight saving time rule parameter exists, to obtain a last day of month m of the current year, and combine the current year, the month m, the obtained last day, the extracted hour H, minute M, and second S into the start time or end time of the daylight saving time.
13. The CPE according to claim 12 , wherein the daylight saving time rule parameter further comprises an offset.
14. The CPE according to claim 12 , further to:
send a prompt when the start time or end time of the daylight saving time of a system arrives.
15. The CPE according to claim 11 , wherein the daylight saving time rule parameter further comprises an offset.
16. The CPE according to claim 10 , wherein the daylight saving time rule parameter further comprises an offset.
17. The CPE according to claim 16 , further to:
send a prompt when the start time or end time of the daylight saving time of a system arrives.
18. The CPE according to claim 10 , further to:
send a prompt when the start time or end time of the daylight saving time of a system arrives.
19. A method for configuring to when to start using daylight saving time and when to stop using daylight saving time in a customer premises equipment (CPE), comprising:
in a server comprising hardware that executes program instructions, and memory having instructions stored therein that instruct the hardware to perform the method:
generating, by the server, a message carrying a daylight saving time rule parameter, wherein the daylight saving time rule parameter comprises: month m, week w, day d, hour H, minute M, and second S, or month m, date D, hour H, minute M, and second S without current year information, and a daylight saving time enable flag; and
sending, by the server, the message carrying the daylight saving time rule parameter and the daylight saving time enable flag to the CPE, so that the CPE obtains start time or end time of daylight saving time through the rule parameter.
