If so, it judges the time information is local summer time and gets the exact time. Otherwise, it is the standard time and gets the exact time. The invention also discloses the network equipment of accessing the exact time information. The invention is used to distinguish the time between summer time and standard time, and different time zones, so as to avoid the time information chaos because of summer time jump and difference of time zones.

Description

A kind of method and network equipment that obtains exact time
Technical field
The present invention relates to the network management technology field, the particularly a kind of definite time method and network equipment of obtaining.
Background technology
In the wireless network, the daylight-saving time saltus step rule that is positioned at the network entity location correspondence of network terminal position may be different, the time zone at network entity place also is not quite similar, the network node that access service is provided for network entity is when managing network entity, because network entity adopts local zone time to describe business information usually, makes that obscuring appears in temporal information in the business information easily.
With telecommunication management network (TMN) model structure is example, and in the TMN network, network element (NE) is the network entity that is in terminal location, and NE saltus step of on-site daylight-saving time rule may be different, and NE also may be in different time zones.Element management system (EMS) is as access node, needs the NE of management self administration, handles the business information that employing local zone time that different N E reports is described, and wherein the information that reports of NE is described with the on-site local zone time of NE.
If the daylight-saving time saltus step takes place in the NE location, the on-site local zone time of NE will duplicate or lose.Suppose NE at local zone time 02:30:00 to reporting service information.If being next second saltus step of summer time 02:59:59, the on-site daylight-saving time saltus step of NE rule becomes standard time 02:00:00, then the NE location jumped to the process of standard time from time daylight-saving time, 02:30:00 can appear twice in local zone time, 02:30:00 also can appear twice in the time in this NE reporting service information, thereby cause EMS can't distinguish in the NE reporting service information, local zone time 02:30:00 is preceding time of daylight-saving time saltus step or the time after the daylight-saving time saltus step.If what NE reported at 02:30:00 is warning information, then EMS can't definitely locate the alarm of NE.In like manner, if being next second saltus step of standard time 01:59:59, the on-site daylight-saving time saltus step of NE rule becomes time daylight-saving time 03:00:00, then when the NE location jumps to time daylight-saving time from the standard time, 02:30:00 to not occur in the local zone time, thereby cause the business information that NE reports among the EMS to be lost.
If the NE of EMS administration is in different time zone, the time of NE reporting service information also causes confusion when showing on EMS easily.For example, the time that is in the NE reporting service information of Dong8Qu is 02:00:00, and at synchronization, the time that is in the NE reporting service information of Dong9Qu then is 03:00:00, thereby make the time of EMS in the business information that synchronization is received different, indigestion when causing the user to read business information on EMS causes obscuring of NE reporting service information time among the EMS.
At present, on-site daylight-saving time rule difference of network entity in the wireless network or network entity are in different time zones, and the heterogeneous networks entity that access node is managed uses the local zone time reporting message usually, makes access node can't judge the definite time of the network entity reporting service message of administering.Network entity is reporting service information when the daylight-saving time saltus step takes place, can cause local zone time in the business information to duplicate or lose, and then cause access node can't carry out the business information location, can't complete collection network entity problems such as performance data.Be in of the asynchronism(-nization) of the network entity of different time zone, cause access node when the operation of the heterogeneous networks entity being carried out with time correlation, cause the confusion of operation in synchronization reporting service message.
Summary of the invention
In view of this, the main purpose of the embodiment of the invention is to propose a kind of method of access node supervising the network entity, in order to determine the definite temporal information in the business information.
The another purpose of the embodiment of the invention is to propose a kind of network equipment, in order to determine the definite temporal information in the business information.
In order to achieve the above object, the technical scheme of the embodiment of the invention is achieved in that
A kind of method of obtaining exact time, this method comprises:
Judge whether the temporal information in the business information comprises the daylight-saving time sign that is used to distinguish time daylight-saving time and standard time, if comprise, judges in the temporal information and adopts time daylight-saving time to describe local zone time, obtains definite temporal information; Otherwise the time is described local zone time when adopting standard in the judgement temporal information, obtains definite temporal information.
A kind of network equipment that obtains exact time, this network equipment comprises control module, judge module;
Described control module is used to receive the business information that comprises temporal information, and the business information that receives is sent to judge module; Reception is obtained definite temporal information from the judged result of the express time information description mode of judge module;
Described judge module, be used for judging whether the described temporal information that receives comprises the daylight-saving time sign that is used to distinguish time daylight-saving time and standard time, if comprise, judge that temporal information is to adopt the local zone time of time daylight-saving time description, sends the daylight-saving time judged result to control module; If do not comprise, judge that temporal information is to adopt the local zone time of standard time description, judged result when control module sends standard.
From such scheme as can be seen, the method of obtaining exact time and the network equipment that the embodiment of the invention provides, according to the daylight-saving time sign that is used to distinguish time daylight-saving time and standard time in the temporal information, the different describing modes of local zone time have been distinguished, obtained temporal information definitely, avoided because of the repetition of carrying out the temporal information that the daylight-saving time hop jump causes or lose.
Access node has been distinguished the business information of network entity at the different local zone times of synchronization transmission by the time-zone information of heterogeneous networks entity.
In addition, access node and network entity can utilize on-site daylight-saving time side-play amount of network entity and/or time-zone information, local zone time is converted into universal coordinated time (UTC) time, has avoided being in the operational confusion of time that different time zone or location daylight-saving time rule difference causes because of network entity.

Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention is clearer, the present invention is described in more detail below in conjunction with embodiment.
In the embodiment of the invention, describedly obtain definite temporal information and be meant the describing mode of determining local zone time in the temporal information.Because adopt different describing modes, the identical time has different description results; Perhaps described, corresponding the different UTC time time come to the same thing.The embodiment of the invention is obtained definite temporal information by determining the describing mode of local zone time.
Obtain definite time method in embodiments of the present invention and be applicable to the wireless network that comprises network entity and access node.Wherein, saltus step of on-site daylight-saving time of network entity rule is different, and perhaps network entity is positioned at different time zones; Access node is used to network entity that access service is provided, and carries out the mutual of information between the network entity.Wherein network entity not only can be the mobile subscriber who crosses over the time zone, also can be the network management layer entity that maybe needs to handle different time zone or daylight-saving time business at the network terminal of fixed location work.For example, in the TMN network, network entity is during as NE, and corresponding EMS is an access node; EMS is during as network entity, and map network management system (NMS) is an access node; In code division multiple access (CDMA) network, base station sub-system (BSS), mobile switching centre (MSC) are during as network entity, and respective operations maintenance centre (OMC) is access node.
Be access node below with EMS, managing the NE that has different daylight-saving times rules or be in different time zone is example, and the definite time method of obtaining in the embodiment of the invention is described.
In the present embodiment, EMS and NE judge respectively whether temporal information has the daylight-saving time sign in the business information, if no daylight-saving time sign in the temporal information, then this temporal information adopts the standard time to describe, if the daylight-saving time sign is arranged in the temporal information, then this temporal information adopts time daylight-saving time to describe, and then determines to adopt the pairing definite moment of temporal information of different describing modes, thereby obtains definite temporal information.
After having obtained definite temporal information,, business information is operated according to this definite temporal information.
As access node, NE is described in detail as network entity and is example with EMS, supposes that the on-site daylight-saving time saltus step of NE rule is that next second saltus step of summer time 02:59:59 becomes standard time 02:00:00.
When NE or the EMS that administers this NE handle interior business information, suppose that the temporal information in the business information is 02:30:00, if do not comprise the daylight-saving time sign in the temporal information, this temporal information is standard time 02:30:00, if comprise the daylight-saving time sign in the temporal information, this temporal information is time daylight-saving time 02:30:00, i.e. standard time 03:30:00, thus time daylight-saving time and standard time are distinguished.
Above-mentioned NE or EMS can carry out subsequent treatment to this business information according to the definite temporal information of having obtained.For example, when giving the user, be " 02:30:00DST " with the time showing that adopts time daylight-saving time to describe with the time showing in the business information, promptly behind local zone time, increase daylight-saving time (DST) character and identify as the daylight-saving time.So, the user can tell the definite moment of identical temporal information correspondence by checking demonstration.
Carry out in the exchange process of business information at EMS and NE, EMS and NE can utilize definite temporal information, and business information is operated.Suppose EMS need inquire about NE at daylight-saving time 02:30:00 to the warning message that sends between the standard time 02:30:00, then send in the querying command of NE at EMS, only in zero-time, comprise daylight-saving time sign.So, NE can distinguish zero-time and concluding time, and return corresponding business information after receiving querying command.
In the present embodiment, access node and network entity be the definite time point by whether comprising in the judgement time information that the daylight-saving time identifies temporal information to describe all, and this is a preferable examples of the present invention.Access node and network entity can use other can distinguish the method for time daylight-saving time and standard time.For example, access node and network entity are provided with the value that the summertime markers is known in the temporal information, when the value of daylight-saving time sign is 1, illustrate that this time information is time daylight-saving time, when the summertime in the time information, the markers knowledge was 0, illustrate that this temporal information is the standard time.In actual applications, the method that can distinguish time daylight-saving time and standard time all within protection scope of the present invention, is not restricted to adopt the method in the present embodiment.
In embodiments of the present invention, access node and network entity can judge that whether local zone time is time daylight-saving time, obtains definite temporal information by whether comprising in the temporal information that the daylight-saving time identifies.The local zone time that can adopt time daylight-saving time to describe if desired be converted to the UTC time, describes with the UTC time thereby temporal information is unified, avoids can't distinguishing the confusion that causes temporal information owing to time daylight-saving time and standard time.
The local zone time and the reduction formula of UTC time that adopt time daylight-saving time to describe are: UTC=local zone time+daylight-saving time side-play amount.The daylight-saving time side-play amount is by NE rule decision of on-site daylight-saving time, and for example, the on-site daylight-saving time rule of NE is: next second saltus step of summer time 02:59:59 becomes standard time 02:00:00, and then the daylight-saving time side-play amount of this NE correspondence is-60 minutes.Be access node with EMS at first below, NE is a network entity, introduces the step that access node and network entity obtained and stored the daylight-saving time side-play amount.
Fig. 1 shows EMS in the embodiment of the invention obtained and stored the daylight-saving time side-play amount from NE flow process.As shown in Figure 1, EMS from the step that NE obtained and stored the daylight-saving time side-play amount is:
Step 11:EMS provides UTC consistency for NE.
EMS provides NTP (Network Time Protocol) (NTP) server for NE, and NE is as the client of ntp server, utilizes existing method of carrying out time synchronized, from ntp server lock in time, guarantees that EMS and NE are in the temporal consistency of UTC.
When EMS or NE need be converted into UTC during the time with time daylight-saving time, between EMS and NE, need to carry out the UTC time synchronized, to guarantee that local zone time is being converted into UTC during the time, EMS is consistent with the time reference between the NE, avoids the confusion on the time of origin.
Step 12:EMS sends querying command to NE, is used to obtain the daylight-saving time side-play amount that NE sets in advance.
EMS can send to NE with querying command by man-machine language (MML).
When EMS had monitored the NE access, EMS sent querying command to the new NE that inserts, and obtains the daylight-saving time side-play amount that this NE sets in advance.EMS also can be regularly the transmission querying command to different NE, obtain the up-to-date daylight-saving time side-play amount that sets of NE.
Step 13:NE sends inquiry request response message to EMS.
After NE receives the querying command that EMS sends, self the on-site daylight-saving time side-play amount that has set in advance is carried in the inquiry request response message, sends to EMS.Wherein the on-site daylight-saving time side-play amount of NE can be started working at NE and be carried out being provided with initialized the time.
EMS receives the inquiry request response message of NE, therefrom obtains and store the on-site daylight-saving time side-play amount of this NE.
By above-mentioned steps, NE sends to EMS with on-site daylight-saving time side-play amount, makes EMS store record NE location daylight-saving time side-play amount.
Fig. 2 shows NE in the embodiment of the invention obtained and stored the daylight-saving time side-play amount from EMS flow process.As shown in Figure 2, NE from the step that EMS obtained and stored the daylight-saving time side-play amount is:
Step 21:EMS provides UTC consistency for NE.
EMS provides ntp server for NE, and NE is as the client of ntp server, utilizes existing method of carrying out time synchronized, from ntp server lock in time, guarantees that EMS and NE are in the temporal consistency of UTC.
Step 22:EMS sends and revises order to NE, and the daylight-saving time side-play amount that EMS is pre-set sends to NE.
EMS can will revise order by MML and send to NE.
When EMS starts working when carrying out initialization, perhaps as the NE that EMS administered when the on-site daylight-saving time, side-play amount changed, be the different NE configuration daylight-saving time side-play amount of institute's administration by EMS is unified, EMS is carried at the daylight-saving time side-play amount that sets during modification orders, and sends to NE.
Step 23:NE sends and revises response message to EMS.
After NE receives the modification order that EMS sends, obtain self the on-site daylight-saving time side-play amount that pre-sets by EMS, revise and store this daylight-saving time side-play amount, and the result that will revise is carried in the modification response message, send to EMS.
EMS receives the modification response message of NE, after determining the modification success of NE to location daylight-saving time side-play amount, and the on-site daylight-saving time side-play amount of NE on EMS foundation and the renewal EMS local record.If NE is to the modification failure of location daylight-saving time side-play amount, EMS does not upgrade the on-site daylight-saving time side-play amount of NE on the local record, continues to send and revises order to NE.
By above-mentioned steps, the different N E location daylight-saving time side-play amount that EMS pre-sets self sends to NE, NE is obtained and stores self location daylight-saving time side-play amount.
In addition, EMS and NE preserve and the process of storage daylight-saving time side-play amount can also be triggered by the NE end.
After NE started working, operating personnel were according to the on-site daylight-saving time rule of NE, the daylight-saving time side-play amount of initialization NE, and after the initialization of the daylight-saving time of NE was finished, NE used MML notice EMS to upgrade the daylight-saving time side-play amount of NE in the local record.
When the on-site daylight-saving time rule of NE changes, NE is according to the daylight-saving time side-play amount of the modifications self of daylight-saving time rule.After the daylight-saving time of NE side-play amount was upgraded, NE used MML notice EMS to upgrade the daylight-saving time side-play amount of NE in the local record.
The foregoing description is the preferable examples that access node or network entity obtained and stored the method for daylight-saving time side-play amount, is not limitation of the present invention.Among the present invention, between access node and network entity in any business information reciprocal process, network entity or access node all can send to the other side by MML or other information transmission modes with the daylight-saving time side-play amount of network entity, make access node or network entity obtain the also daylight-saving time side-play amount of storage networking entity.
EMS or NE are after receiving the business information that comprises temporal information, EMS or NE utilize the daylight-saving time side-play amount of having stored, the local zone time that adopts time daylight-saving time to describe is converted into the UTC time, adopt UTC that temporal information is described, avoid the problem of time of occurrence information confusion, and then business information is operated.
Wherein, process and EMS that EMS utilizes the UTC time that business information is operated utilize the daylight-saving time to identify the similar process that business information is operated, process and NE that NE utilizes the UTC time that business information is operated utilize the daylight-saving time to identify the similar process that business information is operated, and do not repeat them here.
When EMS and NE utilize the UTC time to carry out business information mutual, suppose that EMS sends querying command, inquiry NE to the warning message that sends between the standard time 02:30:00, in querying command, only comprises the daylight-saving time sign at time daylight-saving time 02:30:00 in the start time information.After NE receives querying command, according to daylight-saving time side-play amount and the conversion formula of UTC time, zero-time 02:30:00 is converted into the 01:30:00 of UTC time, do not comprise the daylight-saving time sign in the concluding time information, promptly adopt the standard time to describe, corresponding daylight-saving time side-play amount is 0, and the UTC time of concluding time correspondence is 02:30:00.So, NE is by being converted to local zone time the UTC time, obtained the definite temporal information of querying command, warning message between the UTC time 01:30:00 to 02:30:00 is sent to EMS, avoided the temporal information confusion that when the daylight-saving time saltus step, causes, even local zone time repeats, also can obtain definite temporal information.
In the present embodiment, NE carries out the UTC time with the temporal information of EMS transmission to be changed, and this is a preferable examples of the present invention, is not restriction.Using when of the present invention, EMS is after receiving the business information that NE sends, and the temporal information in can business information converts the UTC time to.EMS and NE are dealing with business information separately or are carrying out business information when mutual, both can use local time daylight-saving time, also can use the UTC time after the conversion, promptly EMS and NE can carry out the conversion of time daylight-saving time and UTC time flexibly according to actual business requirement.
When using the embodiment of the invention, can arrange the describing mode of temporal information in the business information each other between EMS and the NE in advance, perhaps be local zone time, perhaps be the UTC time, avoid causing the confusion of business information conversion by the difference of temporal information describing mode.The step of concrete time conversion can also be realized arranging between EMS and the NE, the confusion of business information conversion can be avoided causing equally by the difference of temporal information describing mode.
In order better to distinguish local zone time and UTC time, in the temporal information of business information, increase and distinguish local zone time and the time marking of UTC time, if the temporal information in the business information is a local zone time, then time marking is 0, if the temporal information in the business information is the UTC time, then time marking is 1.So, EMS and NE can carry out different processing to business information according to time marking, the confusion of the business information that causes in the difference of avoiding by the temporal information describing mode.
Still sending querying command with EMS is example to NE, suppose EMS need inquire about NE at time daylight-saving time 02:30:00 to the warning message that sends between the standard time 02:30:00, EMS is according to daylight-saving time rule and the conversion formula of UTC time preserved, zero-time 02:30:00 is converted into the 01:30:00 of UTC time, and the UTC time of standard time 02:30:00 correspondence is 02:30:00.EMS is provided with time marking in temporal information in sending to the querying command of NE, the time marking of zero-time and concluding time all is set to 1.So, receive the querying command of EMS at NE after, can directly warning message between the UTC time 01:30:00 to 02:30:00 be sent to EMS.
When the network entity of administering when access node does not need to carry out the daylight-saving time saltus step, for example do not have or when rule not enabled daylight-saving time when the network entity location that access node is administered, the on-site time-zone information of network entity that access node is administered different according to institute is discerned the business information of heterogeneous networks entity transmission.Wherein, the method for access node and network entity storage time-zone information is identical with the method for access node and network entity preservation daylight-saving time rule, does not repeat them here.Access node or network entity can be converted to local zone time the UTC time if desired, use the UTC time to describe thereby temporal information is unified, avoid because access node is administered the confusion that heterogeneous networks entity time zone difference causes temporal information.
The reduction formula of local zone time that time-zone information is different and UTC time is: UTC=local zone time+time-zone information.Wherein, time-zone information is by the time zone decision at NE place, and for example, NE is in Dong8Qu, and then the time-zone information of this NE correspondence is-8.
Be access node below with EMS, NE is that network entity is an example, the embodiment of the invention is obtained definite time method describe.
When NE that EMS administered does not need to carry out the daylight-saving time saltus step, but the different NE that EMS administered is when being in different time zones, and EMS utilizes the conversion formula of local zone time and UTC time, and the local zone time that will be positioned at the NE of different time zone is converted to the UTC time.Suppose that in the present embodiment the NE that EMS administered is in Dong8Qu, the time-zone information of this NE correspondence is-8, and the 2nd NE that EMS administered is in Dong9Qu, and the time-zone information of this NE correspondence is-9.
When the on-site local zone time reporting service information of the NE employing that is in different time zone self was given EMS, EMS was converted to the UTC time with local zone time, thereby obtains definite temporal information.For example, in the same UTC time, the time of a NE reporting service information is 10:00, and the time of the 2nd NE reporting service information is 11:00.After EMS receives the different business information of local zone time, according to local zone time and the conversion formula of UTC time, the UTC time that calculates the local zone time correspondence in the business information that different N E reports is 02:00, thereby learn that a NE and the 2nd NE report at synchronization in the business information of the asynchronism(-nization) that reports, when being convenient to the user and on EMS, reading the information that NE reports, the definite time of identification NE reporting information.
In like manner, the NE that is in different time zone can calculate the UTC time of local zone time correspondence, will adopt the information of UTC time to report EMS.
Above-mentioned EMS can utilize the different local zone time of time-zone information and the reduction formula of UTC time and NE, and business information is operated.Sending the operational order that has temporal information with EMS is example to the NE that is in different time zone, suppose EMS need inquire about different N E at UTC time 01:00 to the information that reports between the 02:00, EMS is according to the time-zone information of a NE and the 2nd NE, calculate the local zone time of UTC time correspondence, in the querying command that sends to a NE, temporal information be 09:00 to 10:00, in sending the querying command of the 2nd NE, temporal information is: 10:00 is to 11:00.
EMS sends the operational order have temporal information when being in the NE of different time zone, can also directly adopt the UTC time to describe temporal information in the operational order.After NE receives the operational order that adopts the UTC description, calculate the local zone time of UTC time correspondence, carry out the operational order that EMS sends.NE also can directly carry out the operational order that EMS sends according to the UTC time.
The network entity of administering when access node has different daylight-saving time rules, and the time zone, place is not simultaneously, and access node obtains definite temporal information according to daylight-saving time sign and the on-site time-zone information of NE of the different NE of administer.The reduction formula that adopted this moment is: UTC=local zone time+daylight-saving time side-play amount+time-zone information.
Be access node below with EMS, NE is that network entity is an example, and the embodiment of the invention is described.
EMS sends the operational order have temporal information and is in different time zone and the different NE of daylight-saving time rule to what administer, the daylight-saving time rule of supposing the NE that EMS administers is: next second saltus step of summer time 02:59:59 becomes standard time 02:00:00, then the daylight-saving time side-play amount of this NE correspondence is-60 minutes, the daylight-saving time rule of the 2nd NE that EMS administered is: next second saltus step of summer time 02:59:59 becomes standard time 01:00:00, then the daylight-saving time side-play amount of this NE correspondence is-120 minutes, and a NE is in Dong8Qu, the time-zone information of the one NE correspondence is-8, the 2nd NE is in Dong9Qu, and the time-zone information of the 2nd NE correspondence is-9.EMS need inquire about different N E at UTC time 01:00 to the information that reports between the 02:00, EMS is according to time-zone information and the daylight-saving time rule of a NE and the 2nd NE, calculate the local zone time of UTC time correspondence, in the querying command that sends to a NE, temporal information is that 10:00 is to 11:00, in the querying command that sends the 2nd NE, temporal information is that 11:00 is to 12:00.
When using the embodiment of the invention, access node and network entity can use daylight-saving time sign and time marking flexibly, utilize daylight-saving time rule and time zone rule to reach the purpose of the definite time of determining business information.
Following correspondence is described in detail with the composition and the function of the network equipment of said method.
Fig. 3 shows the composition structure of the network equipment in the embodiment of the invention, as shown in Figure 3, in the network equipment in embodiments of the present invention, comprises control module, judge module, application module, computing module and memory module.
