Fig. 3 is a kind of flow diagram of service shunting method provided in an embodiment of the present invention, referring to Fig. 3, this method packetInclude following steps.
Step 201: service distributing equipment receives the first domain Name acquisition request that user equipment is sent, first domain Name acquisitionRequest includes the domain name index information of the user equipment.
It, should when user plays the Internet resources such as some web page news, video, audio by the user equipment requestsUser equipment can send the first domain Name acquisition that the domain name index information comprising the user equipment is sent to service distributing equipmentRequest, first domain Name acquisition request can be DNS (Domain Name Serve, domain name service) request.Specifically, when shouldWhen user equipment sends the request of the first domain Name acquisition, which first can be sent to base station for the request of the first domain Name acquisition,So that first domain Name acquisition request is sent to service distributing equipment by base station.
Wherein, which refers to the information of the business domain name for indexing the user equipment.For example, working as the useWhen the address of the Internet resources of family device request is www.***.com, which can be the www.***.com.Certainly, in practical applications, which may be other information, and the embodiment of the present invention does not do specific limit to thisIt is fixed.
Step 202: service distributing equipment determines the business domain name of the user equipment according to the domain name index information.
When service distributing equipment is according to the domain name index information, when determining the business domain name of the user equipment, service distributingEquipment can inquire local server, and the query result returned according to local server according to the domain name index information, determineThe business domain name of the user equipment.
Wherein, service distributing equipment can be with according to the process that the domain name index information inquires local server are as follows: stepRapid 2021, service distributing equipment sends domain name inquiry request to local server, and inquiry of the domain name request is indexed comprising the domain nameInformation, when local server receives inquiry of the domain name request, local server can be inquired according to the domain name index informationFirst corresponding relationship；Wherein, the first corresponding relationship includes corresponding between default domain name index information and pre-set business domain nameRelationship.Step 2022a, it is local to take if there are the corresponding first business domain names of the domain name index information in the first corresponding relationshipThe first business domain name is sent to service distributing equipment by business device；Step 2022b, if the domain name is not present in the first corresponding relationshipThe corresponding first business domain name of index information, then local server does not inquire domain name index letter to the transmission of service distributing equipmentCease the response message of corresponding first business domain name.
It should be noted that the pre-set business domain name that the first corresponding relationship includes in local server can be third party and answerThe business domain name stored in local server with platform according to the member registration information of user equipment.For example, if user equipmentMember registration information be www.***.com- (uid, priority), priority be the user equipment User Priority,Then www.***.com can be domain name index information by local server, by (uid, priority) as the user equipmentBusiness domain name.
In addition, according to the query result that local server returns, service distributing equipment determines the business domains of the user equipmentThe process of name can specifically be divided into two kinds of situations, be illustrated separately below.
The first, as shown in figure 4, step 2023: when service distributing equipment receive local server transmission the first industryWhen domain name of being engaged in, service distributing equipment can determine whether the first business domain name matches with resource address information, if the first domain name ropeFuse breath is determined as the business domain name of the user equipment then by the first business domain name with resource address information matches.
Optionally, when service distributing equipment determines whether the first business domain name matches with resource address information, service distributingEquipment can directly match the first business domain name with resource address information, obtain matching result；Alternatively, service distributing is setAfter matching to the first business domain name with resource address information, resource address information can also be sent to local serviceDevice matches local server with the first business domain name in the first corresponding relationship according to the resource address information, and willMatching result returns, and service distributing equipment carries out true according to the matching result that itself matching result and local server returnIt is fixed, if the matching result that the matching result of itself and local server return is successful match, it is determined that the first business domain nameWith resource address information matches.
It should be noted that the resource address information can be uniform resource locator (Uniform ResourceLocator, URL), which refers to the address of the Internet resources of user's request.In addition, the resource address information can be the useThe resource address information for including in the first session connection request that family equipment is sent, first session connection request can be the useWhat family equipment was sent after the query result that service distributing equipment receives local server return.
In addition, if the first business domains are entitled (uid, priority), resource address information is URL, when determining the first businessWhen whether domain name matches with resource address information, be the uid and URL of the first business domain name are subjected to string matching, if firstThe uid of business domain name is consistent with URL, it is determined that otherwise the first business domain name and resource address information matches determine the first businessDomain name and resource address information mismatch.
Optionally, when service distributing equipment receives the first business domain name of local server transmission, service distributing is setIt is standby that the response message for getting the first business domain name can be sent to the user equipment, when the user equipment receives response letterWhen breath, which can send the first session connection request including resource address information to business local device.
Second, as shown in Figure 5 or Figure 6, if meeting the first preset condition, service distributing equipment determines the user equipmentThe process of business domain name can be with are as follows: step 2024, service distributing equipment sends the second domain Name acquisition to common domain name serverRequest, the request of the second domain Name acquisition include the domain name index information；Step 2025, when common domain name server receive this secondWhen domain Name acquisition is requested, common domain name server can be that the user equipment distributes corresponding business according to the domain name index informationDomain name, and the business domain name distributed for the user equipment is sent to service distributing equipment, so that service distributing equipment receives public affairsName server is the business domain name of user equipment distribution altogether.
Wherein, the first preset condition includes one of the following: being not present and domain name index information in the first corresponding relationshipCorresponding business domain name；Alternatively, there is the first business domain name corresponding with the domain name index information in the first corresponding relationship, and reallyFixed first business domain name and the resource address information mismatch.It that is to say, when service distributing equipment receives local server hairWhen that send does not inquire the response message of the corresponding first business domain name of the domain name index information or service distributing equipment receivesWhen to the first business domain name and determining that the first business domain name and the resource address information mismatch, service distributing equipment can rootThe business domain name of the user equipment is determined according to method described in second situation.
Further, when service distributing equipment method according to second situation determines the business of the user equipmentAfter domain name, this method further include: step 2026, service distributing equipment sends the first session connection response to the user equipment；Step 2027, when the user equipment receives the first session connection response, which can be according to the first session connectionResponse sends the second session connection request；Wherein, the first session connection response and the second session connection request are included as publicThe business domain name of name server user equipment distribution.
Step 203: service distributing equipment is according to the business domain name of the user equipment, extremely by the service distributing of the user equipmentServer corresponding with the business domain name of the user equipment, the server are local server or remote server.
Wherein, the business domain name of the user equipment is determined according to the first situation in step 202 when service distributing equipmentWhen, according to the business domain name of the user equipment, by the service distributing of the user equipment to the business domain name pair with the user equipmentThe server answered specifically: service distributing equipment is according to the business domain name of the user equipment, in the user equipment and local serviceSession connection is established between device, by the service distributing of the user equipment to local server, to reduce the biography of business datumDefeated time delay mitigates the burden of core net.
In turn, after service distributing equipment is by the service distributing of the user equipment to local server, if local serverIt is middle to that is to say there are the session data of the user equipment requests, when the network in local server there are the user equipment requestsWhen resource, corresponding session data directly can be provided for the user equipment by local server；If in local server notThere are when the session data of the user equipment requests, service distributing equipment can also send session data to remote server and askIt asks, so that remote server beats into corresponding session data in local server, to be the use by local serverThe corresponding session data of family equipment.
When service distributing equipment determines the business domain name of the user equipment according to the second situation in step 202, rootAccording to the business domain name of the user equipment, by the service distributing of the user equipment to clothes corresponding with the business domain name of the user equipmentBe engaged in implement body are as follows: when service distributing equipment receives the second session connection request, service distributing equipment the user equipment withSession connection is established between remote server, by the service distributing of the user equipment to remote server.In turn, when business pointFlow device can be provided after the service distributing to remote server of the user equipment by remote server for the user equipmentThe requested session data of the user equipment.
It further, further include the corresponding User Priority of the user equipment in the business domain name of the user equipment, referring toFig. 7, after service distributing equipment is by the service distributing of the user equipment to local server, this method further include: step204- step 205.
Step 204: service distributing equipment receives the service resources parameter for the user equipment that base station is sent.
Wherein, after service distributing equipment is by the service distributing of the user equipment to local server, base station can be withThe service resources reporting parameters of the user equipment are given to service distributing equipment, so that service distributing equipment receives the user equipmentService resources parameter.
Optionally, service resources parameter is throughput, the throughput multiple biographies according to corresponding to the user equipmentDefeated resource and transmission power on each transfer resource and noise gain are determined.Specifically determine the user equipmentThe method of throughput may refer to the relevant technologies, this is not set forth in detail in the embodiment of the present invention.
Step 205: if meeting the second preset condition, service distributing equipment is user equipment transmission by local serverSession data corresponding with default resource parameters, the default resource parameters User Priority corresponding with the user equipment are corresponding.Wherein, the second preset condition is one of the following: the service resources parameter of the user equipment is more than or equal to default resource parameters；Alternatively, the service resources parameter of the user equipment is less than default resource parameters, service distributing equipment sends instruction information to base station,So that base station is that the user equipment distributes after corresponding transfer resource according to the instruction information.
Wherein, User Priority can be with multiple priority levels, can when the User Priority includes two priority levelsTo include high priority and low priority, and different User Priorities corresponds to different default resource parameters, different usersPriority corresponds to different grades of Internet resources.Optionally, when the service resources parameter that base station is sent is throughput, this is defaultResource parameters can be default throughput, and the corresponding default throughput of high priority can be greater than corresponding preset of low priority and handle upRate, the grade of the Internet resources of corresponding high priority can also be greater than the grade of the Internet resources of low priority.
For example, User Priority includes high priority and low priority, if user equipment 1 if the Internet resources are videoUser be gold member, user equipment 2 be silver member, then user equipment 1 be high priority and corresponding default throughputIt can be T1080P, user equipment 2 is low priority and corresponding default throughput can be T720P, wherein 1080P and 720P canThink the clarity of the corresponding video of different user priority.
Specifically, when service distributing equipment receives the service resources parameter, it can be according to the business of the user equipmentThe User Priority for including in domain name determines default resource parameters corresponding with the User Priority of the user equipment, later, willDetermining default resource parameters are compared with the service resources parameter.If the service resources parameter of the user equipment is more than or equal toThe default resource parameters, then service distributing equipment can be provided for the user equipment by local server and preset resource ginseng with thisThe corresponding session data of number.If the service resources parameter of the user equipment is less than the default resource parameters, service distributing equipmentInstruction information can be sent to base station, when base station receives the instruction information, base station can be corresponding for user equipment distributionTransfer resource, and be after the user equipment distributes corresponding transfer resource in base station, service distributing equipment passes through local clothesBusiness device provides for the user equipment and presets the corresponding session data of resource parameters with this.In turn, service distributing equipment root can be madeDifferentiated service is carried out according to business of the different User Priorities to user equipment, ensure that the stabilization of high-priority users businessProperty, improve user experience.
When base station is that the user equipment distributes corresponding transfer resource, base station can detecte PRB on different frequency sub-bandThe state of " busy " and " spare time ", if there is the PRB in " spare time " state in frequency sub-band where the corresponding PRB of the user equipment,More PRB are distributed first from the frequency sub-band where the corresponding PRB of the user equipment for the user equipment in base station, until the useThe service resources parameter of family equipment is more than or equal to the corresponding default resource parameters of User Priority of the user equipment, when distributingIt, can be from other son frequencies when PRB in frequency sub-band in journey where the corresponding PRB of the user equipment in " spare time " state is inadequateSection is that the user equipment continues to distribute.If there is no " spare time " states of being in the frequency sub-band where the corresponding PRB of the user equipmentPRB, then more PRB are distributed from other frequency sub-band for the user equipment in base station, equally until the business of the user equipmentResource parameters are more than or equal to the corresponding default resource parameters of User Priority of the user equipment.
Optionally, when base station from other frequency sub-band for the user equipment distribute more PRB when, base station can be according to itFrequency sub-band where his frequency sub-band PRB corresponding with the user equipment is followed successively by user equipment distribution by nearly farther away sequenceCorresponding PRB.
For example, the available frequency sub-band in base station includes B1, B2, B3 and B4, it include 20 PRB in each frequency sub-band, if the useEquipment corresponding PRB in family is in frequency sub-band B1, and when the service resources parameter of the user equipment is less than default resource parameters, base station canTo distribute corresponding PRB from the PRB in frequency sub-band B1 in " spare time " state first for the user equipment.
It should be noted that the service distributing equipment in the embodiment of the present invention can individually dispose in a communications system,Deployment can be merged with base station, the embodiment of the present invention is not specifically limited in this embodiment.

Wherein, User Priority can be with multiple priority levels, can when the User Priority includes two priority levelsTo include high priority and low priority, and different User Priorities corresponds to different default resource parameters, different usersPriority corresponds to different grades of Internet resources.Optionally, when the service resources parameter that base station is sent is throughput, this is defaultResource parameters can be default throughput, and the corresponding default throughput of high priority can be greater than corresponding preset of low priority and handle upRate, the grade of the Internet resources of corresponding high priority can also be greater than the grade of the Internet resources of low priority.
Specifically, service distributing equipment can be according to the user when receiving unit 301 receives the service resources parameterThe User Priority for including in the business domain name of equipment determines default resource ginseng corresponding with the User Priority of the user equipmentNumber, later, determining default resource parameters are compared with the service resources parameter.If the service resources of the user equipment are joinedNumber is more than or equal to the default resource parameters, then service distributing equipment can be provided and be somebody's turn to do for the user equipment by local serverThe default corresponding session data of resource parameters.If the service resources parameter of the user equipment is less than the default resource parameters, industryBeing engaged in shunting device can be to base station transmission instruction information, and when base station receives the instruction information, base station can set for the userBack-up matches corresponding transfer resource, and is service distributing equipment after the user equipment distributes corresponding transfer resource in base stationIt is provided by local server for the user equipment and presets the corresponding session data of resource parameters with this.In turn, business can be madeShunting device carries out differentiated service according to business of the different User Priorities to user equipment, ensure that high-priority usersThe stability of business, improves user experience.
When base station is that the user equipment distributes corresponding transfer resource, base station can detecte PRB on different frequency sub-bandThe state of " busy " and " spare time ", if there is the PRB in " spare time " state in frequency sub-band where the corresponding PRB of the user equipment,More PRB are distributed first from the frequency sub-band where the corresponding PRB of the user equipment for the user equipment in base station, until the useThe service resources parameter of family equipment is more than or equal to the corresponding default resource parameters of User Priority of the user equipment, when distributingIt, can be from other son frequencies when PRB in frequency sub-band in journey where the corresponding PRB of the user equipment in " spare time " state is inadequateSection is that the user equipment continues to distribute.If there is no " spare time " states of being in the frequency sub-band where the corresponding PRB of the user equipmentPRB, then more PRB are distributed from other frequency sub-band for the user equipment in base station, equally until the business of the user equipmentResource parameters are more than or equal to the corresponding default resource parameters of User Priority of the user equipment.
Optionally, when base station from other frequency sub-band for the user equipment distribute more PRB when, base station can be according to itFrequency sub-band where his frequency sub-band PRB corresponding with the user equipment is followed successively by user equipment distribution by nearly farther away sequenceCorresponding PRB.
Service distributing equipment provided in an embodiment of the present invention is asked by receiving the first domain Name acquisition that user equipment is sentThe domain name index information asked, and include according to the request of the first domain Name acquisition, determines the business domain name of the user equipment, later basisThe business domain name of the user equipment, by the service distributing of the user equipment to service corresponding with the business domain name of the user equipmentDevice, which is local server or remote server, so as to reduce the propagation delay time of business datum, raising user's bodyIt tests, while mitigating the burden of core net.
