TECHNICAL FIELD
[0001] The disclosure relates to the field of communications, and in particular to a method and an apparatus for realizing summer time in a Code Division Multiple Address (CDMA) system.
BACKGROUND
[0002] In Code Division Multiple Address (CDMA) system synchronization information, a Daylight field indicates whether summer time is started. After receiving the system synchronization information, a mobile phone performs corresponding processing for the time displayed by the mobile phone according to a mark indicating whether the summer time is started. However, in a practical application, mobile phones manufactured by some manufacturers do not respond to the mark, so it is necessary to seek for a new method to realize summer time when the CDMA system is used in some countries in which a summer time adjustment is needed, so as to ensure that all the mobile phones can re-adjust the time displayed by the mobile phone after the summer time is started.
[0003] Different from a mobile phone of other systems, the time displayed by a CDMA mobile phone is obtained through receiving system synchronization information, and is specifically calculated out according to "system time" and "time zone offset" in the synchronization information. The "system time" is actually the Global Positioning System (GPS) time, namely satellite standard clock time, which is represented by systime in the synchronization information. The "time zone offset" is generated due to the fact that the earth is divided into different time zones according to different longitudes of various places, which is represented by LocalTimeOffset in the synchronization information. The value ranges from -24 to 26, and the unit is 30 minutes, which is determined by the time zone where the base station system is situated; the positive value range represents the eastern hemisphere, and the negative value range represents the western hemisphere, for example, the Beijing time corresponds to the "Eastern Eight Zone", so the parameter is set as 16 by base station systems used in China.
[0004] The time displayed by a mobile phone is the time of the place where the mobile phone is situated, obtained according to the GPS time and a time zone offset. In the past, the parameter is adjusted manually to realize the summer time, thus the summer time can only be displayed on the mobile phone, while all the other time in the base station system are non-summer time, for example, information reporting time points in all the background maintenance tools are non-summer time, and when the user (maintenance personnel) uses the background maintenance tools, all the tool time is non-summer time. This shows that the summer time realizing mechanism in the prior art is an "illusion" only displayed by a mobile phone, and the summer time function is not completely realized.

BRIEF DESCRIPTION OF THE DRAWINGS
DETAILED DESCRIPTION
[0022] The specific embodiments of the disclosure are described below in detail with reference to the accompanying drawing.
[0023] A method for realizing summer time in a Code Division Multiple Address (CDMA) system according to an embodiment of the disclosure can be performed according to the following processing steps:
- (1) a base station detects a summer time state of the current system; and
- (2) according to the detected summer time state of the system, the base station configures a time zone offset in system synchronization information as the summation of or the difference between a standard time zone offset and a summer time offset time, or maintains as the standard time zone offset, and then sends the system synchronization information to a terminal.
[0024] As shown in Fig. 1, a base station receives a summer time offset time and a summer time effective time period configured by a network manager. In the network manager, a user can modify the summer time offset time and the summer time effective time period at any time, and after each modification, the network manager sends the latest summer time offset time and summer time effective time period to the base station. The summer time offset time and the summer time effective time period are configured by the user itself according to the requirements, so the flexibility of the system is improved.
[0025] The base station detects the summer time state of the current system in a periodical detection way; if the detection period is not met, it directly terminates the adjustment to the summer time, and if the detection period is met, it firstly detects whether the current time is within the configured summer time effective time period.
[0026] After receiving the system summer time effective time period, the base station automatically detects a starting and stopping time of the summer time, if the system detects that the current time is not within the summer time effective time period, configures a summer time mark as stopped, and reads a current summer time offset time; and if the system detects that the current time is within the summer time effective time period, configures the summer time mark as started, and reads the current summer time offset time. The summer time mark is used for determining a summer time state of the system. In order to facilitate determining the summer time state of the system, when the system runs for the first time, the summer time mark is configured as stop. The user presets the summer time effective time period, thus increasing the ease of use of the system.
[0027] The base station determines the summer time state of the current system through detecting the summer time mark, and then compares the current summer time mark with the last stored summer time mark; if the detected summer time mark jumps from stopped to started, the base station determines that the system comes to a summer time entering state; if the detected summer time mark jumps from started to stopped, the base station determines that the system comes to a summer time leaving state; if the detected summer time mark has no jumping and indicates started, the base station determines that the system is in a summer time maintaining state; and if the detected summer time mark has no jumping and indicates stopped, the base station determines that the system is in a non-summer time state. It is simple and easy to determine the summer time state of the system by using the summer time mark, and the system resources are saved.
[0028] As shown in Fig. 1, if the system summer time state detected by the base station is summer time entering, the base station configures the time zone offset in the system synchronization information as the summation of the standard time zone offset and the summer time offset time; if the system summer time state detected by the base station is summer time maintaining, the base station configures the time zone offset in the system synchronization information as the summation of the standard time zone offset and a new summer time offset time when the summer time offset time changes, and maintains as the standard time zone offset if the summer time offset time does not change; if the system summer time state detected by the base station is summer time leaving, the base station configures the time zone offset in the system synchronization information as the difference between the standard time zone offset and the summer time offset time; if the summer time state detected by the base station is a non-summer time state, the base station directly terminates the adjustment to the time zone offset.
[0029] After terminating the adjustment to the time zone offset, the system stores the current summer time mark and the summer time offset time, and sends the system synchronization information including the summer time information to the terminal. The stored current summer time mark and the summer time offset time are used for summer time state determination and summer time adjustment in the next detection period.
[0030] After receiving the system synchronization information, the terminal calculates a current time to realize the summer time; the method for calculating the current time by the terminal is: system time + time zone offset, wherein the system time is the Global Positioning System (GPS) time; and the time zone offset consists of a standard time zone offset and a summer time offset time, wherein the standard time zone offset is a time parameter configured according to different time zones where the base station is situated, its value ranging from -24 to 26, with a minimum unit of 30 minutes, the positive value range representing the eastern hemisphere and the negative value range representing the western hemisphere, and, the summer time offset time can be a negative value, of which the unit is 30 minutes. The terminal calculates the current summer time state according to the system synchronization information, so the reliability of summer time configuration is improved. The system synchronization information including the summer time adjusting information is sent by the base station to the terminal, so that the summer time is realized for both the base station and the terminal.
[0031] The disclosure also provides an apparatus for realizing summer time in a CDMA system, comprising a terminal and a summer time adjusting module arranged on a base station, wherein:
the summer time adjusting module is configured for detecting a summer time state of the current system, and according to the detected summer time state of the system, configuring a time zone offset in system synchronization information as the summation of or the difference between a standard time zone offset and a summer time offset time, or maintaining as the standard time zone offset, and then sending the system synchronization information to the terminal.
[0032] The summer time adjusting module detecting the summer time state of the current system comprises: the summer time adjusting module determines the summer time state of the system through detecting a summer time mark; if the detected summer time mark jumps from stopped to started, the summer time adjusting module determines that the system comes to a summer time entering state; if the detected summer time mark jumps from started to stopped, the summer time adjusting module determines that the system comes to a summer time leaving state; if the detected summer time mark has no jumping and indicates started, the summer time adjusting module determines that the system is in a summer time maintaining state; and if the detected summer time mark has no jumping and indicates stopped, the summer time adjusting module determines that the system is in a non-summer time state.
[0033] According to the detected system summer time state, the summer time adjusting module configuring the time zone offset in the system synchronization information as the summation of or the difference between the standard time zone offset and the summer time offset time, or maintaining as the standard time zone offset comprises:
if the summer time state of the system detected by the summer time adjusting module is summer time entering, the summer time adjusting module configures the time zone offset in the system synchronization information as the summation of the standard time zone offset and the summer time offset time;

if the summer time state of the system detected by the summer time adjusting module is summer time leaving, the summer time adjusting module configures the time zone offset in the system synchronization information as the difference between the standard time zone offset and the summer time offset time;
if the summer time state detected by the summer time adjusting module is a non-summer time state, the summer time adjusting module directly terminates the adjustment to the time zone offset.
[0034] The terminal is further configured for, after receiving the system synchronization information, calculating a current time to realize the summer time; the terminal calculating the current time comprises: obtaining the summation of a system time and the time zone offset as the current time, wherein the system time is a GPS time.
[0035] The base station further comprises a network manager parameter receiving unit, which is configured for receiving a summer time effective time period and summer time offset time configured through a network manager, and for automatically detecting the starting and stopping time of the summer time according to the received system summer time effective time period; and, for configuring a summer time mark as started if the system detects that the current time is within the summer time effective time period, and configuring the summer time mark as stopped if the system detects that the current time is not within the summer time effective time period.

[0037] The base station further comprises a storage module, which is configured for storing a current summer time mark and the summer time offset time before the system synchronization information is send to the terminal.
[0038] Aiming at the defect that some terminals cannot respond to a summer time start mark to realize summer time, the method and apparatus for realizing summer time in a CDMA system of this disclosure realize the summer time in a way of a base station receiving a summer time offset time and a summer time effective time period configured through a network manager, then determining a summer time state of the system and, modifying a time zone offset and sending it to the terminal according to different summer time states. The summer time realization is effective for all the terminals, thus the reliability of summer time is enhanced, and meanwhile the base station system time, background maintenance tool time and terminal display time are exactly the same, and the summer time function is realized simultaneously.
