Specific embodiment

Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application is explicitly described.

It should be understood that, the technical solution of the application can be applied to various communication systems, such as: global system for mobile telecommunications (Global System of Mobile communication, referred to as " GSM ") system, CDMA (Code Division Multiple Access, referred to as " CDMA ") system, wideband code division multiple access (Wideband Code Division Multiple Access, referred to as " WCDMA ") system, General Packet Radio Service (General Packet Radio Service, referred to as " GPRS "), LTE system, advanced long term evolution (Advan Ced long term evolution, referred to as " LTE-A ") system, Universal Mobile Telecommunication System, referred to as " UMTS ") or next generation communication system, such as, 5th Dai Tongxin (fifth-generation, referred to as " 5G ") etc..

For ease of understanding, Fig. 1 is combined briefly to introduce the protocol stack of Evolved UMTS Terrestrial wireless access network (Evolved UMTS Terrestrial Radio Access Network, referred to as " E-UTRAN ") interface first.

Fig. 1 shows the schematic diagram of the protocol stack of MME and eNB.By Fig. 1, it can be seen that, in current LTE network, the subscriber signaling transmission between MME equipment and eNB equipment uses S1-AP agreement, which guarantees the transmission of subscriber signaling, and transport layer protocol uses Stream Control Transmission Protocol.

Therefore, if normally communicating between MME and eNB, need to guarantee the link of each layer shown in Fig. 1 all in normal condition.For example, will lead to if SCTP link is abnormal and be unable to normal communication between MME and eNB；If SCTP link is normal, and S1AP link is abnormal, also results in and is unable to normal communication between MME and eNB.

In other words, S1 interface includes the link of the protocol entity composition of each layer equity, for example, at least includes: SCTP link, S1AP link etc..

Similarly, the X2 interface between base station, for example, subscriber signaling transmission uses X2-AP agreement, and transport layer protocol uses Stream Control Transmission Protocol between eNB and eNB.X2 interface includes the link that the protocol entity of each layer equity is constituted, and for example, at least includes: SCTP link, X2AP link etc..

Hereinafter, by taking the link of S1 interface as an example, the embodiment of the present application is described in detail for convenience of understanding and illustrating.

As described above, it is normal in SCTP link and in the case where S1AP link exception, will lead to and be unable to normal communication between MME and eNB.But the exception of S1AP link is possible to following several situations occur:

Situation a, eNB side is normal, and the side MME is abnormal；

Situation b, eNB side is abnormal, and the side MME is normal；

All there is exception in situation c, eNB side and the side MME.

It is appreciated that the appearance of any one situation can all cause to be unable to normal communication between MME and eNB in three cases above.If there is situation c, the side eNB can trigger S1AP in SCTP link exception and establish (Setup) process；If there is situation b, because the side eNB can not transmit the message to MME, eNB can actively discharge SCTP link, and to notify the MME link of opposite end abnormal, MME discharges S1AP link, and then eNB actively initiates S1AP Setup process；If there is situation a, because the side eNB can send a message to MME, and MME is because itself is abnormal without making any processing, and eNB will not actively initiate S1 foundation (Setup) process because being not aware that the side MME failure.Therefore, the embodiment of the present application proposes a kind of processing method of communication interface failure mainly for the scene.

The embodiment of the present application in order to facilitate understanding is illustrated in combination with fig. 2 the detailed process of S1 foundation first.Fig. 2 shows the schematic flow chart that S1 is established from the angle of equipment interaction.As shown in Fig. 2, S1 Establishing process specifically includes the following steps:

201, in transport layer, eNB sends SCTP link initialization (SCTP Init) message to MME；

202, MME sends SCTP link initialization to eNB and responds (SCTP Init Ack) message, carries caching (Cookie) in the SCTP Init Ack message；

203, eNB sends SCTP cache responses (SCTP Cookie Echo) message to MME；

204, MME sends SCTP cache responses feedback (SCTP Cookie Echo Ack) message to eNB.At this point, SCTP link establishment (Established) is completed；

205, in protocol layer, eNB sends S1 to MME and establishes (S1Setup) message；

206, MME sends S1 to eNB and establishes response (S1Setup Response) message.At this point, S1AP link establishment is completed.

By the above process, it can be seen that, above-mentioned steps 201 to 204 are the process of SCTP link establishment, after setting up SCTP link, further establish S1AP link by step 205 and 206.Although this should not constitute any restriction to the application it should be noted that illustrating only the foundation of SCTP link and S1AP link in Fig. 2.It will be understood to those skilled in the art that release S1AP link, it can be understood as by S1AP layers and the link information of its lower layer (e.g., including SCTP layers, IP layers etc., specifically may refer to Fig. 1) all discharges.Establish S1AP link, it can be understood as all set up the link between S1AP layers and its lower layer.In other words, S1AP link and SCTP link share the protocol entity of SCTP layers and its following layers.

It should be noted that the reconstruction of S1AP link can only be initiated by eNB, that is to say, that for MME extremely and in the case that eNB is unknown, eNB will not actively initiate S1AP link re-establishment above situation a.Accordingly, it is desirable to provide a kind of method, can trigger eNB and actively initiate S1AP link re-establishment in the case where MME exception.

Fig. 3 to Fig. 5 shows the schematic flow chart of the processing method of the communication interface failure according to the embodiment of the present application.It should be understood that Fig. 3 to Fig. 5 shows the communication steps or operation of the processing method of the communication interface failure of the embodiment of the present application, but these steps or operation are only examples, and the deformation of other operations or the various operations in figure can also be performed in the embodiment of the present application.In addition, each step in figure can be executed according to the sequence different from what is presented in figure, and it is possible to not really want all operationss in execution figure.

It should be noted that, each step in the processing method of communication interface failure shown in each figure can be executed by first network equipment, in the case where the first communication interface is the scene of S1 interface, the first network equipment is connect with second network equipment by S1 interface communication, the first network equipment can be access network equipment, second network equipment can be equipment of the core network, transport layer link can be SCTP link, application layer link can be S1AP link (situation one, corresponding diagram 3), or, the first network equipment can be equipment of the core network, second network equipment can be access network equipment, transport layer link can be SCTP link, application layer link can be S1AP link (situation two, corresponding diagram 4)；In the case where the first communication interface is the scene of X2 interface, the first network equipment and second network equipment are communicated to connect by X2 interface, the first network equipment and second network equipment can be access network equipment, transport layer link can be SCTP link, application layer link can be X2AP link (situation three, corresponding diagram 5).

It should be noted that SCTP link can be understood as providing the link of stable, orderly data transport service between two endpoints (for example, MME and eNB, alternatively, the first eNB and the 2nd eNB). It is a kind of reliable data-message transmission agreement based on the agreement (for example, IP) for providing unreliable transmission services.It is for providing connection-oriented reliable data-message transmission.Endpoint is the basic logic concept of SCTP, is logic transmitting terminal and the receiving end of data message, is a typical logic entity.For example, in the embodiment of the present application, transmitting terminal can be MME, and receiving end can be eNB, and for transmitting terminal MME, local terminal is its own, opposite end eNB, and for the eNB of receiving end, this as its own, opposite end MME.

SCTP endpoint is identified by one group of transmission address with identical SCTP port numbers, and Stream Control Transmission Protocol provides and to be only capable of establishing a connection between two endpoints.So SCTP endpoint may have multiple transmission addresses, but there are unique port numbers in these transmission addresses.

In the embodiment of the present application, access network equipment can be WLAN (Wireless Local Area Networks, referred to as " WLAN ") in access point (Access Point, referred to as " AP "), base station (Base Transceiver Station in GSM or CDMA, referred to as " BTS "), base station (the NodeB being also possible in WCDMA, referred to as " NB "), it can also be evolved base station (the Evolutional Node B in LTE, referred to as " eNode B " or " eNB "), or relay station or access point, or mobile unit, wearable device and gNB in future 5G network or future drill Into public land mobile network (Public Land Mobile Network, referred to as " PLMN ") network in the network equipment etc..

In the embodiment of the present application, equipment of the core network can be MME, and MME is control plane network element, is mainly responsible for the control planes function such as mobile management and session management of user equipment.

Below in conjunction with Fig. 3 to Fig. 5 and above-described three kinds of situations, the processing method of the communication interface failure according to the embodiment of the present application is described in detail.

Situation one:

Fig. 3 shows the schematic flow chart of the processing method 300 of the communication interface failure according to one embodiment of the application.In the method 300 shown in Fig. 3, first network equipment can be eNB, and second network equipment can be MME.It should be understood that constituting any restriction without coping with the application it is only for example.

As shown in figure 3, this method 300 includes:

S310, eNB determine whether the success rate for the business transmitted by S1 interface meets preset condition.

Pass through the success rate for the business that S1 interface transmits, it is possible to understand that be used to indicate an index by S1 interface normal communication.In the embodiment of the present application, since the communication link is related to service layer, it is properly termed as service success rate, alternatively, being referred to as the success rate of communication, message response rate etc..This Application is to this and is not particularly limited.Specifically, when link is in normal communication state, the interaction between local terminal and opposite end is normal, and the probability that can suffer from the failures such as communication disruption, loss of traffic is smaller, that is, success rate is higher；When link is in abnormality, interacting between local terminal and opposite end is abnormal, and the probability that may cause the failures such as communication disruption, loss of traffic is larger, that is, success rate is lower.

As a possible embodiment, which can monitor whether the certain message issued obtain responding to determine by the end eNB.Such as, in user equipment (User Equipment, referred to as " UE ") in booting up attachment process, or, in tracking area update (Tracking Area Update, referred to as " TAU ") in process, or, in paging (Paging) process that core net is actively initiated, eNB can send initial UE message (Initial UE message) to MME, in the normal situation of link, MME can send initial context to eNB and establish request (Initial context setup request) message.

Here, for convenient for distinguishing and illustrating, by first network equipment (such as, the eNB) send message be denoted as first message, the message that second network equipment (for example, MME) that first network equipment (for example, the eNB) receives is sent is denoted as second message.

Optionally, S310 can be specifically included:

First message that the eNB is sent in the first preset period of time by S1 interface and by S1 interface to the total quantity of second message whether be less than preset first thresholding.

Specifically, which can preset a period (to be denoted as the first preset period of time convenient for distinguishing and illustrating), and monitoring sends and receives the total quantity of message by the S1 interface in first preset period of time.For example, first preset period of time can be 8:00 to 20:00.When monitoring to be less than preset first thresholding by the total quantity of the S1 interface messaging in first preset period of time, determine that the success rate for the business that the eNB is transmitted by S1 interface meets preset condition, and then determine abnormal state.

It can be understood that, since the region that eNB is covered is different, telephone traffic is not also identical, such as, the telephone traffic in mountain area and city just has very big difference, and therefore, the first corresponding thresholding may also be different, covering the first thresholding corresponding to the eNB in mountain area may be smaller, and covering the first thresholding corresponding to the eNB in city may be larger.

Optionally, S310 can be specifically included:

The eNB determines whether be less than preset second thresholding by the quantity of S1 interface to second message and the ratio of the quantity of the first message sent by S1 interface in the second preset period of time.

Specifically, the eNB can preset a period (for convenient for distinguishing and illustrate, it is denoted as the second preset period of time), the ratio of the quantity of the quantity for the second message that the eNB is arrived by S1 interface and the first message of transmission is monitored in second preset period of time, it should in second preset period of time if monitoring The ratio of the quantity of the first message of the quantity and transmission for the second message that eNB is arrived by the S1 interface is less than preset second thresholding, determines that the success rate for the business that the eNB is transmitted by S1 interface meets preset condition, and then determine abnormal state.

Further, since the ratio is also related to the telephone traffic of the eNB to a certain extent, i.e., related to the region that eNB is covered.Can in conjunction with the eNB first message sent in second preset period of time by S1 interface and by S1 interface to second message total quantity it is whether abnormal come the S1 interface for determining local terminal.

Optionally, before the eNB is determined and is less than preset second thresholding by the ratio of the quantity of S1 interface to second message and the quantity of the first message sent by S1 interface in the second preset period of time, this method further include:

The eNB determine the first message sent in the second preset period of time by S1 interface and by S1 interface to second message total quantity more than or equal to preset third thresholding.

Wherein, preset third thresholding can be understood as a sample size, i.e., when eNB, which is determined, meets the thresholding of sample size by the quantity of S1 interface messaging in the second preset period of time, just further determine that whether the ratio of number of the first message of the second message and transmission that receive is less than preset second thresholding.For example, eNB determine in the second preset period of time by the quantity of S1 interface messaging meet sample size thresholding (such as, 100 message) when, just further determine that whether the S1 interface only has sent 100 message in second preset period of time, and any message is not received, alternatively, the message number sent is far longer than the quantity of the message received.Namely monitor the S1 interface whether " only export but no import ".

It is understood that the preset third thresholding is equally related to the telephone traffic of the eNB.

It should be noted that above the first cited preset period of time and the second preset period of time are only to distinguish two different determination methods, the period that first preset period of time and the second preset period of time can be identical or different for duration, the application is to this and is not particularly limited.In the case where the first preset period of time is identical duration with the second preset period of time, the method whether above two judgement service success rate meets preset condition can be used in combination, at this point, preset first thresholding is identical as preset third thresholding.That is, first judging whether be greater than or equal to preset first thresholding by the quantity of S1 interface messaging in the first preset period of time.If it is not, the S1 interface for then directly determining the side eNB is abnormal；If, then further determine that in first preset period of time by S1 interface to the quantity of second message and the ratio of quantity of first message of transmission whether be greater than preset second thresholding, if not, then determine that the S1 interface of the side eNB is abnormal, if, it then determines that the S1 interface of the side eNB is normal, does not need temporarily to handle.

Due to the first message that the eNB in method as described above, monitored is sent, MME can carry out replying or not replying.If all first messages in sample collected all do not need MME reply, even if the quantity for detecting the first message that eNB is sent is the whole of sample, and the quantity of second message is zero, also not necessarily can determine that the S1 interface of the side eNB is abnormal.

Therefore, in order to improve robustness, which can be further improved the accuracy rate of judgement, can include at least the second message that part opposite end must reply in predefined monitored first message.That is, MME is being communicated under normal circumstances, it is necessary to reply second message to the eNB if eNB sends the first message to MME by S1 interface.In this way, the first message received whether can be directed to according to MME is replied second message more accurately to determine service success rate.In this case, the success rate of the business can be understood as message response rate.

In the embodiment of the present application, it is non-limiting as example, the first message can be initial user equipment message (Initial UE message), which is that initial context establishes request (Initial context setup request) message.

By the above method, eNB can determine the S1 interface fault of local terminal.

S320, eNB discharge SCTP link (that is, an example of transport layer link) when the success rate for determining the business transmitted by S1 interface meets preset condition.

ENB needs to rebuild S1 interface after determining the S1 interface fault of local terminal.But since MME is not aware that the S1 interface fault of the side eNB, in MME, S1 interface is normal.Therefore, eNB can notify the MME S1 interface fault of opposite end by way of discharging SCTP link.After eNB discharges SCTP link, opposite end (that is, MME) can be made to discharge S1AP link by the handshake mechanism between SCTP entity.Specifically, eNB discharges SCTP link, it can be understood as release SCTP link information and entity.Wherein, SCTP link information includes: IP address, local terminal and the port numbers of opposite end of local terminal and opposite end, the information such as entity number (in other words, instance number) and link No. of SCTP layers and following layers.MME discharge S1AP link, it can be understood as whether S1AP link information and entity.Wherein, S1AP link information includes: the entity number (in other words, instance number) of S1AP layers and following layers.

It should be understood that the particular content of the particular content of SCTP link information listed above, S1AP link information, release SCTP link and release S1AP link is merely illustrative, any restriction is constituted without coping with the application.

Optionally, S320 can be specifically included:

ENB determines whether SCTP link is normal；

ENB discharges SCTP link when determining that SCTP link is normal.

Since eNB is when determining S1 interface fault, and uncertain only S1AP layers of link failure or SCTP layers of link failure, the even more link failure of bottom.Therefore, eNB can determine whether SCTP layers of link are normal before rebuilding S1 link.If SCTP layers of link are normal, illustrate all to be normal from SCTP layers of link down, and only there is exception in S1AP layers of link, as long as directly initiating S1AP link re-establishment.If SCTP link is abnormal, also need to further determine that the reason of SCTP layers of link exception.

If SCTP layers of link are normal, eNB can directly initiate the reconstruction of S1 link；If SCTP layers of link are abnormal, eNB can detect by the prior art and repair SCTP link, if still detecting after repairing SCTP link, S1 interface is abnormal, and the processing method of the communication interface failure of the embodiment of the present application can be used to rebuild S1AP link.

It should be understood that the detection of SCTP link failure can be realized with reparation by method in the prior art, and this is also and where not this Applicant's Abstract graph core, for sake of simplicity, omitting the detailed description to its detailed process here.

S330, eNB rebuild S1AP link (that is, an example of application layer link).

It is understood that the process that eNB rebuilds S1AP link includes rebuilding the process of SCTP link, the detailed process that eNB rebuilds S1AP link hereinbefore has been combined Fig. 2 detailed description, for sake of simplicity, which is not described herein again.

S1 interface restores to work normally as a result,.

In the embodiment of the present application, the S1 interface of local terminal can be monitored in real time in eNB, when detecting that service success rate meets preset condition, can execute the above method 300 to repair S1 interface, normal in order to communicate fast quick-recovery.

The processing method of the communication interface failure of the embodiment of the present application is determined by eNB and actively initiates the reconstruction of S1 link in the case where meeting preset condition by the success rate of S1 interface transmission services.Therefore, link failure can be timely detected in the case where exception occurs in the side MME, and quickly carry out link repair, to improve the self-healing ability of S1 interface, avoid as both ends Interface status it is inconsistent caused by service success rate decline the problem of, improve the reliability of S1 interface.

Situation two:

It is appreciated that the above method is equally applicable under the side eNB exception, the normal situation in the side MME.

Fig. 4 shows the schematic flow chart of the processing method 400 of the communication interface failure according to another embodiment of the application.In the method 400 shown in Fig. 4, first network equipment can be MME, second The network equipment can be eNB, and transport layer link can be SCTP link, and application layer link can be S1AP link.It should be understood that constituting any restriction without coping with the application it is only for example.

As shown in figure 4, this method 400 includes:

S410, MME determine whether the success rate for the business transmitted by S1 interface meets preset condition.

As a possible embodiment, which can monitor whether the certain message issued obtain responding to determine by the end MME.For example, MME can send carrying foundation/modification request to eNB in the process that MME establishes carrying, in the normal situation of link, eNB can be sent out to MME send carrying foundation/modification response.

Optionally, S410 can be specifically included:

First message that the MME is sent in the first preset period of time by S1 interface and by S1 interface to the total quantity of second message whether be less than preset first thresholding.

Optionally, S410 can be specifically included:

The MME determines whether be less than preset second thresholding by the quantity of S1 interface to second message and the ratio of the quantity of the first message sent by S1 interface in the second preset period of time.
