Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In recent years, in order to meet the low latency requirement of communication services, network architecture gradually evolves toward a flattened structure. In the 4G, 5G network architecture, the network devices are no longer connected via the radio network controller, but rather are directly connected to the core network. For example, in a 4G network architecture, a base station (Evolved Node B, eNodeB) may be connected to a mobility management entity (Mobility Management Entity, MME) in the core network, and in a 5G network architecture, a base station (Next Generation Node B, gmodeb) may be connected to an access and mobility function (Access and Mobility Management Function, AMF) in the core network.
Meanwhile, in the core network, mobility management network elements (MME or AMF) are all networked in a pooling mode. One or more mobility management element POOLs (MME POOL or AMF POOL) may be provided in a core network, each mobility management element POOL at least comprising one mobility management element, each mobility management element belonging to only one mobility management element POOL, and one mobility management element POOL being capable of establishing a connection with one or more network devices. Therefore, the network device needs to establish connection with all mobility management network elements in the same pool group, and ensures that the link state between the network device and the network elements is normal, thereby providing normal communication service for users.
Taking a 4G network as an example, when a User Equipment (UE) initiates an attachment to an MME through a base station, the MME allocates a globally unique temporary identifier (Globally Unique Temporary Identifier, GUTI) to the UE after the attachment is successful. The GUTI includes information for uniquely identifying the MME to which the GUTI is assigned, and this part of information includes at least two parts, an MME Group identifier (i.e., home MME POOL) and an MME code. And then, when the UE needs to send other signaling messages, the identity mark carried by the signaling message can contain MME codes, and the base station sends the message to the corresponding MME according to the MME codes. Therefore, the base station needs to ensure that the link states with all the MMEs in the MME POOL are normal, otherwise, the traffic of some users cannot be sent to the corresponding MMEs, so that the users cannot use the traffic.
In the prior art, when the link state of the network device is abnormal, the conventional means have difficulty in finding such hidden problems. Usually, after the communication service is affected, a maintainer can detect the link state between the related network device and the mobility management network element according to the information fed back by the user, so as to determine the abnormal link of the network device.
However, in the existing method for detecting the link state of the network device, it is difficult to timely find an abnormal link between the network device and the mobility management network element before the user communication service is affected to perform feedback.
In order to solve the technical problems, embodiments of the present application provide a method, an apparatus, and a device for detecting a link state of a network device. In the embodiment of the application, by analyzing whether the network equipment establishes connection with all network elements in the same mobility management network element pool, abnormal links between the network equipment and the mobility management network elements can be timely found, and the influence on the user communication service is reduced.
The following describes an application scenario of the method for detecting a link state of a network device according to the present application.

After that, the server 101 may send the abnormal link information of the network device to the terminal device 102, so as to notify the staff to detect or maintain the abnormal link of the network device in time.
It should be noted that, in some embodiments, the server 101 may send the abnormal link information of the network device to the terminal device 102, so as to notify the staff to obtain the related information. In other embodiments, the staff may also obtain the abnormal link information of the network device directly through the server 101, which is not limited in this embodiment of the present application.
The server may be, but is not limited to, a single network server, a server group formed by a plurality of network servers, or a cloud based on cloud computing and formed by a large number of computers or network servers.
The terminal device may be a mobile phone (mobile phone), a tablet computer (pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an augmented reality (augmented reality, AR) terminal device, a wireless terminal in self driving (self driving), a wireless terminal in teleoperation (remote medical surgery), a wireless terminal in smart grid (smart grid), a wireless terminal in smart home (smart home), etc. In the embodiment of the present application, the device for implementing the function of the terminal may be the terminal, or may be a device capable of supporting the terminal to implement the function, for example, a chip system, and the device may be installed in the terminal. In the embodiment of the application, the chip system can be formed by a chip, and can also comprise the chip and other discrete devices.
It should be understood that the application scenario of the technical solution of the present application may be a detection scenario of a link state of the network device in fig. 1, but is not limited thereto, and may also be applied to other scenarios where the link state of the network device needs to be detected.
It may be understood that the method for detecting the link state of the network device may be implemented by the device for detecting the link state of the network device provided by the embodiment of the present application, and the device for detecting the link state of the network device may be part or all of a certain device, for example, a server.
The following describes in detail a technical solution of an embodiment of the present application with specific embodiments by taking a server integrated with or installed with related execution codes as an example. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.
Fig. 2 is a flow chart of a method for detecting a link state of a network device according to an embodiment of the present application, where the embodiment relates to a detection process of an abnormal link of the network device. As shown in fig. 2, the method includes:
s201, acquiring data of network equipment accessed to a mobility management network element.
In the embodiment of the application, the server can firstly acquire the data of the network equipment accessed to the mobility management network element, and then determine the abnormal link of the network equipment by processing and analyzing the data.
It should be noted that, the mobility management network element may include network elements such as MME or AMF in the core network, which is not limited in this embodiment of the present application. The network device may provide communication coverage for a particular geographic area and may communicate with terminal devices located within the coverage area. In some embodiments, the network device may be an access network device, and illustratively may include an evolved base station (Evolutional Node B, eNB or eNodeB) in an LTE system, or a base station (Next Generation Node B, gNB or gndeb) in a 5G network, or the like, but is not limited thereto.
The embodiment of the application does not limit the specific content of the data of the network equipment accessed to the mobility management network element. In some embodiments, each mobility management network element may be connected to at least one network device, and the data may include field information such as mobile country codes of all network devices corresponding to the mobility management network element, mobile network numbers of the network devices, and office numbers of the network devices. Exemplary, table 1 is a data list of a network device accessing a mobility management network element according to an embodiment of the present application. In table 1, taking a 4G network as an example, the mobility management network element may be an MME, the network device may be a base station (eNodeB), and information such as a mobile country code, a mobile network number, an office number, and a name of an access MME of the base station are shown in table 1.
TABLE 1
The embodiment of the application does not limit the method for acquiring the data of the network equipment accessing the mobility management network element. In some embodiments, the server may obtain relevant data from each mobility management element separately, in other embodiments, the server may also obtain data of a network device accessing the mobility management element through the integrated network management system. The server may, for example, obtain data of all base stations with which a connection is established through the mobility management network element "GZMME 11".
In other embodiments, after the data of the network device accessing the mobility management network element is acquired, the identifier of the network device may also be generated according to field information in the data of the network device. The embodiment of the application does not limit the generation method of the identification of the network equipment. In some embodiments, field information such as a mobile country code, a mobile network number, an office number, etc. of the network device may be combined to generate the identifier of the network device. For example, referring to table 1, mme "gzmme11" corresponds to a base station with mobile country code "460", mobile network number "01", and office direction number "262146", and the combination of field information of the base station may generate an identifier "46001262146" of the base station. Table 2 is an identification list of a network device provided in an embodiment of the present application.
TABLE 2
| Network element name | Identification of base station |
| GZMME11 | 46001262146 |
| GZMME11 | 46001262148 |
In other embodiments, the data of the pool of mobility management elements may also be acquired after the data of the network device accessing the mobility management element is acquired. The data of the mobility management element pool may include the name of the mobility management element pool to be detected, the name and the number of mobility management elements in each mobility management element pool, and the embodiment of the present application is not limited thereto. Exemplary, table 3 is a data list of a mobility management element pool provided in an embodiment of the present application. In table 3, taking a 4G network as an example, the mobility management element POOL may be MME POOL, and information such as the number and names of network elements (MMEs) contained in the MME POOL is shown in table 3.
TABLE 3 Table 3
S202, determining a mobility management network element pool corresponding to the network equipment according to the data of the network equipment and the data of the mobility management network element pool.
In this step, after the data of the network device is acquired, the mobility management element pool corresponding to the network device may be determined according to the data of the network device and the data of the mobility management element pool.
The application does not limit how to determine the mobility management network element pool corresponding to the network device. In some embodiments, if the mobility management element to which the network device has access is within the pool of mobility management elements, it is determined that the network device corresponds to the pool of mobility management elements. For example, referring to tables 2 and 3, the base station identified as "46001262146" corresponds to MME "GZMME11", and MME "GZMME11" is in the network element POOL "02MME POOL", it may be determined that the base station identified as "46001262146" corresponds to the network element POOL "02MME POOL".
In other embodiments, after determining that the network device corresponds to the mobility management element pool, the server may further establish a mapping table of the identity of the network device, the mobility management element, and the mobility management element pool according to the data of the network device and the data of the mobility management element pool. The method for establishing the mapping relation table in the embodiment of the present application is not limited, and table 4 is an exemplary mapping relation table of the identifier of the network device, the mobility management network element and the mobility management network element pool provided in the embodiment of the present application.
TABLE 4 Table 4
S203, determining an abnormal link of the network equipment according to the mobility management network element pool corresponding to the network equipment.
In this step, after determining the mobility management element pool corresponding to the network device, an abnormal link of the network device may be determined according to the mobility management element pool corresponding to the network device.
The embodiment of the application does not limit the method for determining the abnormal link of the network equipment. In some embodiments, if the number of mobility management network elements accessed by the network device is less than the number of mobility management network elements in the mobility management network element pool corresponding to the network device, determining that an abnormal link exists in the network device. Illustratively, as shown in table 4, 3 MMEs, respectively, "GZMME8", "GZMME9", "GZMME16", are included in 01MME POOL. And the network equipment marked as '46001102147', corresponding to 3 MMEs in the 01MME POOL, is equal to the total number of MMEs in the 01MME POOL, and judging that the link of the network equipment marked as '46001102147' and the network element POOL '01 MME POOL' is normal. And the network equipment marked as '46001102148' corresponds to 2 MMEs in the network element POOL '01 MME POOL', is smaller than the total number of MMEs in the network element POOL '01 MME POOL', and judges that an abnormal link exists between the network equipment marked as '46001102148' and the network element POOL '01 MME POOL'.
Further, if the network device does not access the first mobility management network element in the mobility management network element pool, determining that a link between the first mobility management network element and the network device is abnormal. Illustratively, referring to table 4, if the network device identified as "46001102148" does not access network element "GZMME9" within network element POOL "01MME POOL", a link anomaly between network element "GZMME9" and the network device identified as "46001102148" may be determined.
In other embodiments, the abnormal link table of the network device may also be output after determining the abnormal link of the network device. In the subsequent process, the staff can detect and maintain the links from the network equipment side and the mobility management network element side according to the abnormal link table. Exemplary, table 5 is an abnormal link list of a network device according to an embodiment of the present application.
