Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In recent years, in order to meet the low latency requirement of communication services, the network architecture gradually evolves toward a flat structure. In 4G, 5G network architectures, network devices are no longer connected to the core network through the radio network controller. For example, in a 4G network architecture, a base station (eNodeB) may be connected to a Mobility Management Entity (MME) in a core network, and in a 5G network architecture, a base station (Next Generation Node B, gnnodeb) may be connected to an Access and Mobility Function (AMF) in the core network.
Meanwhile, in the core network, mobility management network elements (MME or AMF) are networked in a pool-organized manner. One core network may have one or more mobility management network element POOLs (MME POOL or AMF POOL), each mobility management network element POOL at least includes one mobility management network element, each mobility management network element belongs to only one mobility management network element POOL, and one mobility management network element POOL may establish contact 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 ensure 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 attach to an MME through a certain base station, after the attach is successful, the MME allocates a Globally Unique Temporary Identifier (GUTI) to the UE. The GUTI includes information for uniquely identifying the MME allocating the GUTI, and this part of information includes at least two parts of MME Group identification (i.e. home MME POOL) and MME coding. Then, when the UE needs to send other signaling messages, the identity carried in the signaling message may include an MME code, and the base station sends the message to the corresponding MME according to the MME code. Therefore, the base station needs to ensure that the link states between the base station and all the MMEs in the MME POOL are normal, otherwise, the service of some users cannot be sent to the corresponding MME, so that the users cannot use the service.
In the prior art, when the link state of the network equipment is abnormal, the conventional means is difficult to find the hidden problem. Usually, after the communication service is affected, the maintenance personnel can detect the link state between the relevant network device and the mobility management network element according to the information fed back by the user, and determine the abnormal link of the network device.
However, the existing method for detecting the link state of the network device is difficult to find the abnormal link between the network device and the mobility management network element in time before the user communication service is affected for feedback.
In order to solve the foregoing technical problem, 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 device establishes connection with all network elements in the same mobility management network element pool, an abnormal link between the network device and the mobility management network element can be found in time, and the influence on the user communication service is reduced.
An application scenario of the method for detecting a link state of a network device according to the present application is described below.
Fig. 1 is a schematic application scenario diagram of a method for detecting a link state of a network device according to an embodiment of the present application. As shown in fig. 1, the server 101 and the terminal apparatus 102 are included. First, the server 101 may obtain data of a network device accessing to a mobility management network element, and then determine an abnormal link of the network device by processing and analyzing the obtained data. After that, the server 101 may send the abnormal link information of the network device to the terminal device 102 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 to notify the staff member to obtain the relevant information. In other embodiments, the staff may also directly obtain the abnormal link information of the network device through the server 101, which is not limited in this embodiment of the application.
The server may be, but is not limited to, a single network server, a server group consisting of a plurality of network servers, or a cloud based on cloud computing, which is composed of a large number of computers or network servers.

In the embodiment of the present application, the apparatus for implementing the function of the terminal may be the terminal, or may be an apparatus capable of supporting the terminal to implement the function, such as a chip system, and the apparatus may be installed in the terminal. In the embodiment of the present application, the chip system may be composed of a chip, and may also include a chip and other discrete devices.
It should be understood that an application scenario of the present technical solution may be a detection scenario of a link state of a network device in fig. 1, but is not limited thereto, and may also be applied to other scenarios that need to detect a link state of a network device.
It can be understood that the method for detecting the link state of the network device may be implemented by the apparatus for detecting the link state of the network device provided in the embodiment of the present application, and the apparatus for detecting the link state of the network device may be a part or all of a certain device, for example, a server.

The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2 is a schematic flowchart 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 process for detecting an abnormal link of a network device. As shown in fig. 2, the method includes:
s201, acquiring data of network equipment accessed to the mobility management network element.
In this embodiment of the present application, the server may first obtain data of the network device accessing the mobility management network element, and then determine the abnormal link of the network device by processing and analyzing the data.
It should be noted that the mobility management network element may include a network element such as an MME or an AMF in a core network, which is not limited in this embodiment of the present application. A network device may provide communication coverage for a particular geographic area and may communicate with terminal devices located within that coverage area. In some embodiments, the network device may be an access network device, and may include, for example and without limitation, an evolved Node B (eNB or eNodeB) in an LTE system, or a base station (Next Generation Node B, gNB or gnnodeb) in a 5G network.
The embodiment of the present application does not limit the specific content of the data of the network device accessing the mobility management network element. In some embodiments, each mobility management element may be connected to at least one network device, and the data may include field information such as a mobile country code, a mobile network number of the network device, and an office direction number of the network device, of all network devices corresponding to the mobility management element. Illustratively, 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 direction number, and a name of an access MME of the base station is shown in table 1.
TABLE 1
The embodiment of the present application does not limit the method for acquiring data of a network device accessing a mobility management network element. In some embodiments, the server may obtain the related data from each mobility management network element, and in other embodiments, the server may also obtain the data of the network device accessing the mobility management network element through the integrated network management system. Illustratively, the server may acquire data of all base stations with which a connection is established through the mobility management network element "GZMME 11".
In other embodiments, after acquiring the data of the network device accessing the mobility management network element, the identifier of the network device may be generated according to field information in the data of the network device. The embodiment of the present application does not limit the method for generating the identifier of the network device. In some embodiments, the identifier of the network device may be generated by combining field information of a mobile country code, a mobile network number, an office direction number, and the like of the network device. For example, referring to table 1, MME "GZMMEs 11" corresponds to base stations with mobile country code "460", mobile network number "01", and office direction number "262146", and the field information of the base stations is combined, so that the identifier "46001262146" of the base station may be generated. Table 2 is an identification list of a network device provided in this embodiment.
TABLE 2
| Network element name | Identification of base station |
| GZMME11 | 46001262146 |
| GZMME11 | 46001262148 |
In other embodiments, after acquiring the data of the network device accessing the mobility management network element, the data of the mobility management network element pool may also be acquired. The data of the mobility management network element pool may include information, such as a name of the mobility management network element pool to be detected, and a name and a number of the mobility management network elements in each mobility management network element pool, which is not limited in this embodiment of the present application. Illustratively, table 3 is a data list of a mobility management network element pool provided in an embodiment of the present application. In table 3, taking a 4G network as an example, the mobility management network element POOL may be an MME POOL, and information such as the number and name of network elements (MMEs) included in the MME POOL is shown in 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 obtained, the mobility management network 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 network element pool.
The method and the device do not limit how to determine the mobility management network element pool corresponding to the network equipment. In some embodiments, if the mobility management network element to which the network device is accessed is in the mobility management network element pool, it is determined that the network device corresponds to the mobility management network element pool. For example, referring to tables 2 and 3, a base station identified as "46001262146" corresponds to MME "GZMMEs 11" and MME "GZMMEs 11" is in network element POOL "02 MME POOL", then it may be determined that a base station identified as "46001262146" corresponds to network element POOL "02 MME POOL".
In other embodiments, after determining that the network device corresponds to the mobility management network element pool, the server may further establish a mapping relationship table of the identifier of the network device, the mobility management network element, and the mobility management network element pool according to the data of the network device and the data of the mobility management network element pool. The method for establishing the mapping relationship table in the embodiment of the present application is not limited, and exemplarily, table 4 is a mapping relationship 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
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 network element pool corresponding to the network device, the abnormal link of the network device may be determined according to the mobility management network element pool corresponding to the network device.
The embodiment of the present application does not limit the method for determining the abnormal link of the network device. 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 a mobility management network element pool corresponding to the network device, it is determined that an abnormal link exists in the network device. Illustratively, as shown in table 4, the 01MME POOL includes 3 MMEs, "GZMMEs 8", "GZMMEs 9", and "GZMMEs 16", respectively. If the network device identified as "46001102147" corresponds to 3 MMEs in the 01MME POOL, and equals to the total number of MMEs in the 01MME POOL, the link of the network device identified as "46001102147" and the network element POOL "01 MME POOL" is determined to be normal. And if the network equipment marked as '46001102148' corresponds to 2MME in the network element POOL '01 MME POOL', and is less than the total number of MME in the network element POOL '01 MME POOL', judging 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 is not accessed to the first mobility management network element in the mobility management network element pool, it is determined that a link between the first mobility management network element and the network device is abnormal. Illustratively, referring to table 4, if a network device identified as "46001102148" does not access network element "GZMMEs 9" within network element POOL "01 MME POOL", then a link anomaly between network element "GZMMEs 9" and a network device identified as "46001102148" may be determined.
In other embodiments, after determining the abnormal link of the network device, the abnormal link table of the network device may be further output. In the subsequent process, the staff can detect and maintain the link from the network equipment side and the mobile management network element side respectively according to the abnormal link table. Illustratively, table 5 is an abnormal link list of a network device provided in the embodiment of the present application.
