Description

Information transferring method and device

Technical field

The application is related to communication technical field, more particularly to information transferring method and device.

Background technology

In the existing network architecture, business platform is deployed in after core network (S/P-GW).With 5G network concepts and The it is proposed of business demand, mobile edge calculations (Mobile Edge Compute, MEC) technology are arisen at the historic moment.By MEC technologies, Business platform can be disposed close to mobile edge.As shown in figure 1, MEC servers and evolved base station (evolved Node B, E-NB), local service server is connected, and is deployed in consolidated network level (close to mobile edge)；MEC servers and point of evolution Connected between group core net (Evolved Packet Core, EPC) by transmission network (such as PTN)；EPC and distal end afterwards Service server is deployed in higher network layer (such as core computer room).

It should be noted that as shown in fig. 1, according to the actual deployment position of business platform, service server is divided For local service server and distal end service server, wherein, for the relative local of distal end, it is intended that non-local deployment.

In Fig. 1, MEC servers are serially connected on the S1 interfaces between e-NB and EPC, the detection based on data message, are realized Local diverter function, specifically include OM and configure local service Template Information (such as local service server ip for MEC servers Location, IP address prefix etc.)；MEC servers obtain UE IP address and UE by monitoring the signaling and service surface data of S1 interfaces Carry the corresponding relation and MEC clothes of (GTP-U (user plane GPRS (GPRS) tunnel protocol) tunnel) information Business device supports the processing of the following two kinds pattern to data message etc. simultaneously.

(1) direct mode operation：For terminal uplink user plane message, if the destination address of terminal access is in PDN networks Distal end address of service server, then MEC servers are by message transmission to public network gateway (S-GW) or Packet Data Network Gateway (P-GW)；For the user plane message from public network S/P-GW, MEC servers are transparent to e-NB, and then are sent to end End.

(2) shunt mode：For terminal uplink user plane message, the server of access is local service server, then MEC Server identifies user plane message, forwards it to local service server；Terminal user face report from local service server Text, MEC servers are put it into terminal GTP-U tunnels according to terminal address, are transmitted to e-NB, and then be sent to terminal.

For shunt mode, it can also be subdivided into end node (End-point, i.e. business end node) and pass through (Pass- Through, i.e. business pass through MEC local business units) two kinds of data forwarding modes, the former transfers to local for the data of shunting Terminated after the related application processing of business platform, the latter then transfers to the data of shunting at the related application of local service platform After reason, distal end business platform processing need to be also reached via EPC.

MEC servers are disposed in a mobile network, can reduce transmission network bandwidth consumption, reduce traffic delay, are improved and are used Family perceives.

But in the prior art, MEC servers are to pass through monitoring to S1 interface protocols between e-NB and EPC according to 3GPP The signaling and service surface data of S1 interfaces carry (GTP-U tunnels) information to obtain UE.Accordingly, there exist following problem：

MEC servers need to monitor S1 interfaces and terminal access (distribution terminal GTP-U tunnel informations), switching (change eventually End GTP-U tunnel informations), the related all signaling procedures of release (recovery GTP-U terminals tunnel information) and analyze it, thus band Carry out larger processing expense and processing postpones；In addition, also exist MEC device interior abnormal restorings miss capture e-NB and EPC it Between opportunity of signaling cause terminal GTP-U tunnel informations may be without the situation that calligraphy learning arrives.

In the case of security protocol (such as IPSec) is enabled between e-NB and EPC, due to S1 interface signaling data encryptions, MEC S1 interface signalings can not be monitored and analyzed to server, therefore can not obtain UE IP address and UE carrying (GTP-U tunnels) information Corresponding relation, so as to which local service diverter function can not be realized；

In the case of multiple-bearer, UE can also have one or more dedicated bearers in addition to default bearing, that is, correspond to multiple GTP-U tunnel informations.MEC servers can not obtain UE flow template (Traffic Flow by S1 interfaces snoop procedure Template, TFT) information, i.e. service message type (five-tuple information) and the corresponding relation of UE carryings (GTP-U tunnels), make Obtain the service surface data locally provided to be difficult to match suitable carrying forwarding, and then have influence on the service quality of business (Quality of Service, QoS).

In summary, mobile edge calculations equipment is set as one relative to e-NB and EPC are transparent in the prior art It is standby, it is deployed in return network.Terminal traffic message based on transmitting after GTP-U protocol encapsulations on the net in passback, but existing skill Art can not efficiently and reliably obtain UE carrying information, and can not by from UE related services message locally applied MEC just Really carry out GTP-U encapsulation.

Table 4

It should be noted that ISI keep-alives, which are called, is considered as success, i.e., when the information type value that information subscribing side is sent is 0 When, ISP returns to success response to information subscribing side.

It is described below on information notification interface (Information Notification Interface, INI)：

This interface interchange person be ISP in itself, for information subscribing side (such as MEC servers) report its be concerned about letter Breath, the information that the information and information subscribing direction ISP of input return is respectively as described in following table 5 and table 6：

Table 5

Table 6

It is described below on ISP frameworks and realization mechanism：

As shown in Fig. 2 in the embodiment of the present application, ISP mainly includes information publisher's administrative unit (Publisher Manager), information subscribing side's administrative unit (Subscriber Manager), release news database (Published Information DB) and information announcement timer (Notification Timer).APPp represents information publisher application, Such as mobility management entity (Mobility Management Entity, MME) etc.；APPs represents the application of information subscribing side, Such as MEC servers.

First, APPp is according to itself available information state, ISP accessing points information (such as the ISP according to advance planning IP address), call the IPI interfaces that ISP is provided to inform its current specifying information, such as UE carryings (GTP-U tunnels) information ISP；

2nd, Publisher Manager are responsible for carrying out the management using releasing news in ISP；

First, Publisher Manager record informations publisher attribute information (Publisher Property), bag Include：

PubEntityID, the input information of the same name from IPI；

PubKeepalive, the input information of the same name from IPI；

Secondly, Publisher Manager are touched by InfoLog events (information for receiving information publisher issue) Hair, the fresh information publishing table (InfoPubTable) in the database that releases news (Published Information DB), According to the PubEntityID of information publisher and InfoID in Published Information DB recording information data bar Mesh (InfoPubEntry).InfoPubTable specific list item is as follows：

PubIndex, the whole unique index value of table；

PubEntityID, the input information of the same name from IPI；

InfoID, the input information of the same name from IPI；

InfoType, the input information of the same name from IPI；

Info, the input information of the same name from IPI.

3rd, the information states of APPs according to their needs, according to the ISP accessing points information of advance planning, such as ISP IP Address, the information requirements that the ISI interfaces for calling ISP to provide it is expected to obtain are notified to ISP.

4th, the Subscriber Manager in ISP are responsible for carrying out the management using subscription information.

First, Subscriber Manager record informations subscriber attribute information (Subscriber Property), bag Include：

SubEntityID, the input information of the same name from ISI；

SubKeepalive, the input information of the same name from ISI.

Secondly, Subscriber Manager (receive the expectation of information subscribing side's transmission by InfoMark events The message of the information requirements of acquisition) triggering, the renewal letter in the database that releases news (Published Information DB) Subscription table (InfoSubTable) is ceased, according to the SubEntityID of information subscribing side and InfoType in Published Record information subscribes to Data Entry (InfoSubEntry) in Information DB.The specific list items of InfoSubTable are as follows：

SubIndex, the whole unique index value of table；

SubEntityID, the input information of the same name from ISI；

PubEntityID, the input information (optional) of the same name from ISI；

InfoType, the input information of the same name from ISI；

SubEntityAddr, information subscribing side address, obtained by ISI interface messages, i.e., the phase sent from information subscribing side Hoping in the message of the information requirements obtained to obtain.

5th, except information releases news in addition to table and information subscribing information table, the database that releases news also needs to safeguard one two The multidate information table (PubSubAssTable) of person's association, to the notice of management information.I.e. when this token record changes, Subscriber Manager are triggered by InfoInd events (i.e. described multidate information table changes), INI is passed through by the latter Interface informs APPs.The specific list items of PubSubAssTable are as follows：

SubIndex, information subscribing table index value；

PubIndex, information issue table index value；

InfoNtfStatus, information announcement state, value 0 represent not notice；1 represents to have noticed；

InfoNtfAttempts, information announcement number of attempt.

Need what is illustrated, the table is to release news to change according to InfoPubTable to become with InfoSubTable subscription information Change dynamic generation, that is to say, that only information publisher has issued information, while has information subscribing side to pull subscription the letter again The information of publisher's issue is ceased, can just there is an entry (PubSubAssEntry), i.e. existence information publisher in this table With the incidence relation of information subscribing side.After the information issued and subscribed to goes issue, respective entries are also removed therewith in this table.

6th, Notification Timer are set up in ISP and are used for ISP to after information subscribing side's notification response timeout Retransmit advertised information.This retransmission process is completed by InfoReInd events (i.e. Notification Timer time-out) triggering, to carry Rise information announcement reliability.It should be noted that its letter is not received in information subscribing side's state normal (i.e. heartbeat is normal) but Periodically (such as setting Notification Timer timing length is 3s) repeating transmission before breath notice confirms.When receiving letter Cease subscriber and confirm response, when either finding out information subscribing side's unreachable (i.e. heartbeat is abnormal) or reaching maximum retransmission, Stop timer and remove information subscribing side's relevant announcement information.

As seen from the above, in information subscribing side, referring to Fig. 3, a kind of information transferring method of the embodiment of the present application offer, wrap Include：

S101, information subscribing side are put down by default information subscribing interface (i.e. above-mentioned ISI) to default information sharing Platform (ISP) sends information subscribing request；

S102, described information subscriber reception described information shared platform are (i.e. above-mentioned by default information notification interface INI) information that pulls subscription of described information subscriber that sends.

S303, when meeting preparatory condition, described information shared platform is ordered by default information notification interface to information The side of readding send record before by information publisher issues, information that the information subscribing side pulls subscription.

It is described to meet preparatory condition, for example, there is information publisher to release news, and there is information subscribing side to pull subscription this Information.

Information publisher's administrative unit in described information shared platform, when receive described information publisher pass through it is default Information issuing interface issue information when, record described information publisher mark and keepalive period, and issue believe Record includes the information publishing table of following information in breath database：The table index value (PubIndex), described information publisher Identify (PubEntityID), the message identification (InfoID) for the information that described information publisher issues, information type (InfoType), the information content (Info).

Information subscribing side's administrative unit of described information shared platform, when receive described information subscriber pass through it is default During the information subscribing request that information subscribing interface is sent, the mark of record described information subscriber and keepalive period, and The record in database that releases news includes the information subscribing table of following information：The table index value (SubIndex), described information are ordered The mark (SubEntityID) for the side of readding, the mark (PubEntityID) of information publisher, described information subscriber pull subscription The information type (InfoType) of information, the address (SubEntityAddr) of described information subscriber.

It is preferred that the multidate information table includes following information：Information subscribing table index value (SubIndex), information hair Cloth table index value (PubIndex), information announcement state (InfoNtfStatus), information announcement number of attempt (InfoNtfAttempts)。

If for example, there is information publisher to release news, and thering is information subscribing side to subscribe to the information, then information hair is recorded Information issue table index value corresponding to cloth side, the incidence relation of information subscribing table index value corresponding with the information subscribing side, and And whether record ISP sends the information announcement state of the information of information publisher issue to the information subscribing side (InfoNtfStatus) number of the information of information publisher issue, i.e. information announcement, and to the information subscribing side are sent Number of attempt (InfoNtfAttempts).

The confirmation message of described information subscriber reply is not received in described information shared platform, and described information is ordered In the case of the side's of readding state is normal, described information shared platform is by described information notification interface, according to default information announcement The timing length of timer, periodically to information subscribing side repeat send record before it is being issued by information publisher, should The information that information subscribing side pulls subscription, until information announcement, number of attempt reaches preset value, such as retransmits 3 times and then abandon weight Pass.

Below so that information subscribing side is MEC servers, information publisher includes e-NB, EPC as an example, it is total to having additional information The MEC networking structures and business data flow direction for enjoying platform are illustrated.

In Fig. 6, Business Stream #1 corresponds to the application (note of direct mode operation：Data are via MEC transparent transmissions)；Business Stream #2 corresponds to End- The application of point data forwarding modes；Business Stream #2+ Business Streams #3 corresponds to the application of Pass-through data forwarding modes.

In Fig. 6, EPC, e-NB mainly realize that information issues (and information goes to issue) process.Illustrate letter by taking MME as an example below Breath issue (and information goes to issue) process.Specifically include：

(1) in the MME planning ISP tie point (such as ISP reference address) related to MEC；

(2) when UE is accessed, MME is in addition to completing existing UE certifications, authentication, attaching process, the IPI interfaces according to ISP The information such as UE IMSI, UE IP address, UE carryings (GTP-U tunnels) information, TFT are published on ISP；

(3) after UE attachment removals, MME according to ISP IPI interfaces by the UE issued before configuration information (including UE The information such as IMSI, UE IP address, UE carryings (GTP-U tunnels) information, TFT) perform and go to issue.

It should be noted that：E-NB issue UE information is optional.When UE is attached to MME, the e-NB of MME and UE access and The SGW interactions being assigned obtain the TE id informations for being respectively this UE distribution, and are allocated to their (corresponding SGW/e-NB).Therefore, Only the information such as UE carryings needed for MEC, TFT are achieved with from MME.For MME, need to only be established in user's attachment, carrying/ Delete, detachment process handles and synchronously issues out by ISP interfaces by UE these information when completing.

In Fig. 6, MEC mainly realizes the subscription procedure of UE carrying informations and receives the UE carrying informations of ISP notices and carry out The process of processing.

UE information management units (UE Info Manager, UIM) are set in MEC, are responsible for matching somebody with somebody for UE bearer related informations Put and safeguard.UIM configures ISP tie points (such as ISP reference address) according to the network planning, alternatively, including related MME network element Or equipment id information.UIM subscribes to UE carrying information according to ISP ISI interfaces when MEC initializes to it.Alternatively, ordering When readding UE carrying information, the network element or equipment of this MEC concerns may specify.In addition, in MEC equipment running process, periodically Heartbeat events are sent to configured in advance ISP, to inform that the current MEC of ISP are in normal operating condition, so as in its exception Its UE subscribed to carrying information is removed afterwards.IMSI, UE-IP, UE that the information that UIM can be subscribed to includes but is not limited to UE are held Carry (GTP-U tunnels) information, traffic flow template (Traffic Flow Template, TFT) information (five-tuple) etc..

After the issue of MME information, ISP notifies the information that this MEC is concerned about by the UE received carrying information by INI interfaces To UIM, it that is to say in MEC runnings, UIM can passively receive the subscription information of ISP transmissions.UIM believes according to the subscription received Breath, the carrying information of one or more service messages is safeguarded for each UE.Specifically include：

UE addresses (UE Address), EPC are the service IP address of UE distribution；

Business Stream direction (Traffic Direction), value Up Link/Down Link；

Protocol type (Protocol Type), i.e., the IP message protocols encapsulated in GTP-U tunnels, value 1 represent internet Internet Control Message Protocol (Internet Control Message Protocol, ICMP)；Value 6 represents transmission control protocol (Transmission Control Protocol, TCP)；Value 17 represents UDP (User Datagram Protocol, UDP) etc.；

Source IP address (Source IP), i.e., the IP message source addresses encapsulated in GTP-U tunnels；

Purpose IP address (Source IP), i.e., the IP message destination addresses encapsulated in GTP-U tunnels；

Source port number (Source Port), i.e., the source port number of the IP messages encapsulated in GTP-U tunnels；

Destination slogan (Destination Port), i.e., the destination slogan of the IP messages encapsulated in GTP-U tunnels；

S-GW addresses (S-GW IP), i.e. S-GW are used for the source address of converting downlink GTP-U messages, or e-NB is used for forwarding The destination address of up GTP-U messages；

S-GW Tunnel Identifiers (S-GW GTU-U TE ID), i.e. S-GW distribution are used for the silent of one UE uplink service of mark Recognize or dedicated bearer；

E-NB addresses (e-NB IP), i.e. e-NB are used for forwarding the source address of up GTP-U messages, or S-GW is used for forwarding The destination address of descending GTP-U messages；

E-NB Tunnel Identifiers (e-NB GTU-U TE ID), i.e. e-NB distribution are used for the silent of one UE downlink business of mark Recognize carrying or dedicated bearer；

EPS carrying marks (EPS Bearer ID, EBI), that is, it is used for distinguishing UE different type carrying；

International mobile subscriber identity (International Mobile Subscriber Identity, IMSI), use Carry out one UE of unique mark；

Default bearing mark, that is, do not set up and carried used in the business of dedicated bearer.

Wherein, TFT information is five-tuple information, divides uplink and downlink both direction, and its content includes protocol type, source IP Address, purpose IP address, source port number and destination slogan.

After MEC obtains above-mentioned UE carrying informations, so that it may the destination for the packet sent according to local service server Location or source address, find corresponding downlink or uplink carrying information and carry out the encapsulation of GTP-U channel messages and send.Specifically Process includes：

Carried out with UE addresses in the data message purpose IP received and the UE carrying information lists obtained by foregoing ISP Compare, if matching, it is determined that the message is downlink business message；

UE addresses are entered in the UE carrying information lists obtained with the data message source IP and MEC that receive by foregoing ISP Row compares, if matching, it is determined that the message is uplink service message；

If it is determined that be descending service message (message for going to e-NB), the descending TFT letters obtained based on said process The corresponding carrying information of breath selection carries out GTP-U channel message encapsulation；

Wherein, downlink bearing selection mode is：With five-tuple information (protocol type, the source ip of the data message received Address, purpose ip addresses, source port number, destination slogan) and the UE that have obtained of MEC one or more than one carryings letter That carrying information of five-tuple information Corresponding matching in breath, the carrying information of the UE as received message encapsulation.

If it is determined that be up service message (message for going to S-GW), the up TFT letters obtained based on said process The corresponding carrying information of breath selection carries out GTP-U channel message encapsulation；

Up carrying selection mode is similar with descending.

The TFT message unmatched is carried out using default bearing (default bearing that i.e. information publisher's core net is informed) GTP-U channel messages encapsulate.
