[0002] In recent years, with the continuous development of various services offered by operators, their service bearer networks have become increasingly complex. In existing network communication service maintenance, the service core network and its bearer and access networks are typically maintained independently. The core, bearer, and access network element network managers manage only their respective network elements and networks. When a fault occurs, maintenance personnel must communicate and exchange information to determine the relationship between the network element, network fault, and service impact. As core bearer networks become increasingly complex, the lack of service detection methods and approaches from a holistic service perspective has become increasingly problematic.

[0108] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0109] As an example, in existing network maintenance, the service core network and its bearer and access networks are typically maintained independently. Core, bearer, and access network element network managers manage their respective network elements and networks. When a fault occurs, maintenance personnel must communicate and exchange information to determine the relationship between the network element, network fault, and service impact. As core bearer networks become increasingly complex, the lack of service monitoring methods and approaches from a holistic service perspective becomes increasingly problematic. This inability to effectively connect various networks and services leads to low efficiency and hinders rapid service detection and fault location.

[0110] In this regard, one of the core inventions of the present invention is to construct a protection relationship model corresponding to the business process based on the business process. During the data communication process, for the data communication network, if a failure is detected in the data communication network, the target network element where the failure occurs can be located, and the target business process corresponding to the target network element can be determined, and the target protection relationship model corresponding to the target business process can be obtained. Then, according to the target protection relationship model, the target business communication link corresponding to the target business process is calculated from the data communication network. The target business communication link includes the mutual access paths between different network elements. Then, according to each mutual access path, it is judged whether the target business communication link is abnormal, and a business detection result for the target business process is generated. The business detection The results include one of normal business information and abnormal business information. By constructing a protection relationship model corresponding to the business process, when a network element fails during data communication, the communication link of the corresponding business process can be calculated based on the protection relationship model, and quickly associated with the affected target business process, so as to provide maintenance personnel with fault cause location and business impact judgment in a timely manner. For business impact judgment, the communication link can be tested to determine whether the business process has failed. By testing the communication status of the communication link, the faulty network element can be located, and the cause of the fault can be quickly located so that maintenance personnel can perform maintenance in a timely manner, thereby ensuring the stability of the business process operation.

[0111] Reference Figure 1 , shows a flowchart of a method for processing network communications provided in an embodiment of the present invention, which is applied to a data communications network. The data communications network includes at least an access network element, a bearer network element, and a core network element. Specifically, the method may include the following steps:

[0112] Step 101: If a fault is detected in the data communication network, the target network element where the fault occurs is located, and a target service process corresponding to the target network element is determined;

[0113] The data communication network can be a mobile communication network, an enterprise office network, or a home network. In the embodiments of the present invention, the data communication network is taken as an example for illustrative description. The data communication network may include an access layer, a bearer layer, and a core layer. The core network element may be a device located at the access layer, the bearer network element may be a device located at the bearer layer, and the core network element may be a device located at the core layer. Among them, the access network element may be responsible for the user terminal's access to the network, and is used to connect the user terminal to the operator's communication network; the bearer network element is responsible for carrying data and aggregating data. When the user terminal accesses the operator's communication network, the data it transmits can be transmitted through the bearer network element; the core network element may be the core part of the communication network, responsible for data processing and routing. The implementation of different business processes requires cooperation between different network elements.

[0114] For business processes, it can be the data transmission process involved in the data communication network for the services provided by the operator. For example, for VOBB (Voice over BroadBand, broadband telephone) services, it can be divided into VOBB registration process, VOBB calling process, VOBB called process, VOBB calling process, inter-network calling process, inter-network calling VOBB process, etc. The data transmission process between network elements involved in different business processes can be different. Therefore, starting from the business process, a protection relationship model based on the business access relationship within the process can be constructed. Through automatic path calculation from network element to network element, it can be determined whether there are still protection-related network elements and accessible paths after a fault occurs, thereby realizing full-process business detection. When a fault occurs on the business path from network element to network element, the affected business processes can be quickly detected and the business impact can be output.

[0115] In an embodiment of the present invention, for a data communication network, a business process and the business access relationship between the access network element, the bearer network element, and the core network element in the business process can be obtained, and a protection relationship model corresponding to the business process can be established based on the business access relationship corresponding to the business process, so that the business process can be detected during its operation through the protection relationship model to determine whether the business process can proceed normally. In a specific implementation, a link group, a protection group, and a network element association relationship corresponding to the business process can be established by adopting the business access relationship, and the network element access segment protection relationship corresponding to the access network element in the business process and the core bearer network protection relationship corresponding to the core network element can be obtained. Then, the link group, the protection group, the network element association relationship, the network element access segment protection relationship, and the core bearer network protection relationship can be combined into a protection relationship model corresponding to the business process.

[0116] Among them, for the service access relationship, it can be the data transmission relationship between different network elements during the operation of the business process, such as the access network element transmitting data to the bearer network element, the bearer network element transmitting data to the core network element, the data transmission between the core network elements, and the one-way or two-way transmission of specific data between the network elements. The service access relationship corresponding to different business processes can be different. The communication links corresponding to the business processes constructed by different network elements can be determined through the service access relationship; the link group can be all links between two devices (i.e., network elements). When all links in the link group between the two devices are interrupted, the link group becomes invalid; the network element association relationship can be for The redundant protection relationship set up for network elements includes setting up bearer network elements in pairs or groups to achieve load bearing, setting up core network elements in pairs or groups to achieve load bearing, and load bearing of network elements connected to edge devices of different offices; the protection group, which can be a link group between different devices and a link group that performs redundant protection of business processes based on the network element association relationship. For example, for user terminals, if there is already an access link, another access link can be constructed as a protection group based on the network element corresponding to the access link and combined with the network element association relationship, so that when the main access link is completely paralyzed, the corresponding business process can continue to be executed based on the protection group.

[0117] In addition, for the network element access segment protection relationship, it can be a protection relationship composed of static routing + BFD (Bidirectional Forwarding Detection), static routing + VRRP (Virtual Router Redundancy Protocol), etc.; for the core bearer network protection relationship, it can be a relationship composed of user edge devices of different business networks and carried by internal gateway protocol.

[0118] In one example, for each service, a corresponding network element link group, protection group, and network element association relationship may be pre-built. The following Table 1 shows the link group:

[0120] Table 1

[0121] The link group table can be shown in Table 2:

[0130] The relationship table between protection groups and devices can be shown in Table 5:

[0131]

[0132] Table 5

[0133] By constructing the above-mentioned protection relationship model corresponding to each business process, when a fault is detected in the data communication network, the target network element where the fault occurs can be located, and the target business process corresponding to the target network element can be determined. In a specific implementation, network elements such as access network elements, bearer network elements, and core network elements can all include communication ports for communicating with other network elements. The first communication port where the fault occurs can be located from the target network element, and the target link group and target protection group where the first communication port is located can be determined. The target business process corresponding to the target link group and target protection group can then be obtained. Specifically, different business processes have different corresponding link groups (and correspondingly different protection groups). Different link groups can communicate through different communication ports. After locating a faulty communication port, the target link group and target protection group to which it belongs can be obtained. The target business process where the fault occurs can then be determined based on the target link group and target protection group, so as to quickly detect the affected business process and output the business impact.

[0134] Step 102: Obtain a target protection relationship model corresponding to the target business process;

[0135] Based on the aforementioned protection relationship model constructed according to the business process, when a fault is detected in the data communication network, after determining the target business process associated with it, it can obtain the corresponding target protection relationship model based on the already constructed protection relationship model, so as to build a protection relationship model based on the business access relationship within the process based on the business process. Through automatic path calculation from network element to network element access, it can determine whether there are still protection relationship network elements and accessible paths after the fault occurs, thereby realizing full-process business detection. When a fault occurs on the business path from network element to network element, it can quickly detect the affected business process and output the business impact.

[0136] Step 103: Calculate a target service communication link corresponding to the target service process from the data communication network according to the target protection relationship model, where the target service communication link includes an inter-access path between different network elements;

[0137] In an embodiment of the present invention, after obtaining the target protection relationship model corresponding to the target business process, the target business communication link corresponding to the target business process can be calculated from the data communication network based on the target protection relationship model. The target business communication link can include the mutual access paths between different network elements to further detect the mutual access paths and determine whether the target business process is affected.

[0138] In a specific implementation, the target protection relationship model may include at least a network element access segment protection relationship and a core bearer network protection relationship. The network element access segment protection relationship is a relationship composed of static routing, a bidirectional forwarding detection protocol, and a virtual router redundancy protocol. The core bearer network protection relationship is a relationship composed of different business network user edge devices and carried by an internal gateway protocol. The network element access segment protection relationship and / or the core bearer network protection relationship can be used to calculate the target business communication link corresponding to the target business process from the data communication network. Based on the protection relationship model, the communication link corresponding to the affected business process can be quickly associated to realize fault location, facilitate maintenance personnel to perform maintenance and analysis, etc., effectively shorten the fault handling time, and reduce communication costs.

[0139] For data communication networks, since the communication links involved in business processes include data communications on different inter-access paths, such as access segment data communication, bearer segment data communication, and core segment data communication, different fault analysis methods can be used to analyze the impact of faults on different inter-access paths on business processes.

[0140] In a specific implementation, if the target network element is an access network element, the first target bearer network element corresponding to the target network element in the target business process can be located, and the first access link between the target network element and the first target bearer network element can be obtained. Then, the target network element association relationship corresponding to the network element access segment protection relationship can be obtained, and the associated access network element associated with the target network element and the second target bearer network element corresponding to the associated access network element can be located based on the target network element association relationship. Then, the first access link between the associated access network element and the second target bearer network element is obtained, and then the first access link and the second access link are used as the target business communication links corresponding to the target business process.

[0141] Among them, the associated access network element can be an access network element corresponding to the target network element set based on the network element association relationship; the first access link can be the main access link of the target network element when executing the target business process, and the second access link can be used as a protection link, for example, referring to Figure 2 , shows a schematic diagram of a communication link provided in an embodiment of the present invention, which may be a communication link constructed based on the link table corresponding to Table 1, wherein for the access network element aBAC1, it may include communication ports such as aPort1 and aPort3, and the corresponding bearer network element CE1 may include communication ports such as zPort2 and zPort4, and the access network element aBAC2 corresponding to the access network element aBAC1 and the bearer network element CE2 form a corresponding protection group. When an alarm is received from the access network element aBAC1 port aPort1, the corresponding target service communication link (i.e. Figure 2 The protection relationship model can be used to quickly associate the communication links corresponding to the affected business processes, thereby facilitating maintenance personnel to perform maintenance and analysis, effectively shortening fault handling time and reducing communication costs.

[0142] In a specific implementation, if the target network element is a core network element, the associated core network element corresponding to the target network element and the terminal core network element in the target business process can be obtained first, and then the intermediate core network elements between the associated core network element and the terminal core network element in the data communication network are traversed to establish an open list and a closed list corresponding to the target network element, wherein the open list can store core network elements to be checked, and the closed list can store core network elements that do not need to be checked. Then, the path cost value corresponding to each intermediate core network element can be obtained, and the associated core network element, the intermediate core network element that meets the conditions, and the terminal core network element can be added to the closed list based on the path cost value to obtain the core network communication link corresponding to the target business process. Among them, the intermediate core network element can be the core network element involved in the transmission of data from the associated core network to the terminal core network element, and the path cost value can be used to represent the distance between the associated core network element and the terminal core network element.

[0143] Specifically, for the calculation process of the core network communication link, the associated core network element can be used as the starting point, and the intermediate core network elements adjacent to the starting point can be traversed to obtain the path cost value corresponding to the intermediate core network elements adjacent to the starting point. The path cost value is used to characterize the distance from the associated core network element to the end core network element. The path cost value is composed of a first cost value and a second cost value. The first cost value is the distance between the associated core network element and the current starting point, and the second cost value is the distance from the current starting point to the end core network element. Then, the intermediate core network element with the smallest path cost value is used as the new starting point, and the original starting point is moved from the open list to the closed list, and the traversal starting point is returned to the corresponding intermediate core network element. The method further comprises the following steps: finding the adjacent intermediate core network elements, obtaining the path cost values corresponding to the intermediate core network elements adjacent to the starting point, iterating in a loop until the starting point is the end core network element, adding the end core network element to the closed list, and stopping the iteration; or stopping the iteration when there is no core network element in the open list, and then constructing the core network communication link corresponding to the target business process based on the core network elements in the closed list. Thus, based on the protection relationship model, the communication link corresponding to the affected business process can be quickly associated to realize fault location, facilitate maintenance personnel to perform maintenance and analysis, etc., effectively shorten the fault handling time, and reduce communication costs.

[0144] During a loop traversal of intermediate core network elements, if the first path cost between the current starting point and an adjacent first intermediate core network element is less than the second path cost between the previous starting point and the first intermediate core network element, the first path cost is used as the current path cost corresponding to the first intermediate core network element, and the traversal returns to the intermediate core network elements adjacent to the starting point to obtain the path cost value corresponding to the intermediate core network elements adjacent to the starting point. Alternatively, if the second intermediate core network element adjacent to the current starting point is not in the open list, the second intermediate core network element is added to the open list, and the traversal returns to the intermediate core network elements adjacent to the starting point to obtain the path cost value corresponding to the intermediate core network elements adjacent to the starting point. In addition, if there are at least two intermediate core network elements with the same path cost, the intermediate core network element with the smallest second cost is used as the new starting point, and the original starting point is moved from the open list to the closed list.

[0145] In one example, assuming that the path cost value is F(cost) estimation = Min(G(cost)+H(cost)), the first cost value is G(cost) = the minimum sum of the edge cost values of the path from the initial starting point to the current starting point, and the second cost value is H(cost) = the estimated distance from the current starting point to the target point (which can be calculated by Manhattan distance). Assume that starting with vertex A (the associated core network element), the starting vertex and its adjacent vertices are placed in the open list. The path cost F(cost) of the adjacent vertices is checked. Vertex B with the lowest path cost is selected as the current vertex. Vertex A is removed from the open set and added to the closed set. Each adjacent vertex of the current vertex is traversed. If the new path to the adjacent vertex is shorter or the adjacent vertex is not in the open set, F(cost) is reset and its parent node is reset to the current vertex B. If any of vertex B's adjacent vertices are not in the open set, the adjacent vertex is added to the open list, with B as its parent node. The path cost F(cost) of the adjacent vertices of the current vertex B is checked, and the vertex with the lowest path cost is selected as the current vertex. Repeat this process until the current vertex is the target vertex. If the F(cost) values are equal, the H(cost) values are compared, and the vertex with the lower H(cost) value continues as the current vertex. Alternatively, when the open list is empty, it indicates that no new vertices can be added, and the absence of a target vertex in the closed list means that the path cannot be found. At this time, the loop ends. Based on the protection relationship model, the communication links corresponding to the affected business processes can be quickly associated to achieve fault location, making it easier for maintenance personnel to perform maintenance and analysis, effectively shortening fault handling time and reducing communication costs.

[0146] For example, assume that the starting point is MCE0 and the target point is MCE8.

[0147] H (cost) value selection: The number of edges required to reach the target point from the vertex multiplied by 100 is the H (cost) value, so as to obtain the F (G (cost) + H (cost)) corresponding to each vertex. For example, refer to Figure 3 , which shows a schematic diagram of a core network element link provided in an embodiment of the present invention. For MCE1, it needs to travel at least three edges (MCE1-MCE3, MCE3-MCE4, and MCE4-MCE8) to reach the target point MCE8, so the H (cost) value is 300. Similarly, the H (cost) value for MCE3 is 200, and the H (cost) value for MCE4 is 100, and so on. Furthermore, the distance between two adjacent vertices is G (cost).

[0148] Step 1: MCE0 is the current vertex, and its adjacent vertices MCE1, MCE3, and MCE4 are stored in the open list. F (cost) is 400, 600, and 500 respectively. Then MCE1 is selected as the current vertex to continue. At this time, the open list [MCE1 [F (400)], MCE3 [F (600)], MCE4 [F (600)]] is opened, and the list [MCE0] is closed; Step 2: Refer to Figure 4 , MCE1 is the current vertex, and its adjacent vertex is MCE3. At this time, the G (cost) value of the new path (MCE0-MCE1-MCE3) from the original starting point to MCE3 is smaller than the previous one (the new path is 100+200, and the old path is 400). Then update the F (cost) value corresponding to MCE3. MCE1 has only one adjacent vertex MCE3, so MCE3 is selected as the current vertex to continue. At this time, the list [MCE3 [F (500)], MCE4 [F (600)]] is opened, and the list [MCE0, MCE1] is closed; Step 3: Refer to Figure 5 , MCE3 is the current vertex, and its adjacent vertices are MCE2 and MCE4. Compare MCE2 [F(500)] and MCE4 [F(600)], and select MCE2 as the current vertex to continue. At this time, the open list [MCE2 [F(500)], MCE4 [F(600)]] is opened, and the closed list [MCE0, MCE1, MCE3] is closed; Step 4: MCE2 is the current vertex, and its only adjacent vertex is MCE8, so MCE8 is used as the current node, and the search ends. The search result is the closed list [MCE0, MCE1, MCE3, MCE2, MCE8]. Therefore, based on the protection relationship model, the communication links corresponding to the affected business processes can be quickly associated to achieve fault location, facilitate maintenance personnel to perform maintenance and analysis, etc., effectively shorten the fault handling time and reduce communication costs.

[0149] Step 104 : determining whether the target service communication link is abnormal according to each of the mutual access paths, and generating a service detection result for the target service process, wherein the service detection result includes one of normal service information and abnormal service information.

[0150] Through the above-mentioned path calculation process, the target business communication link corresponding to the target business process can be obtained. The target business communication link may include several mutual access paths. Then, based on each mutual access path, it is judged whether the target business communication link is abnormal, and a business detection result for the target business process is generated. The business detection result includes one of normal business information and abnormal business information. Therefore, for the data communication network, by constructing a protection relationship model corresponding to the business process, during the data communication process, when a network element fails, the communication link of the corresponding business process can be calculated based on the protection relationship model, and the communication link can be detected to determine whether the business process fails. On the one hand, it realizes the rapid detection of the business process status. On the other hand, by detecting the communication status of the communication link, the faulty network element can be located, and the cause of the failure can be quickly located so that maintenance personnel can perform maintenance in time, thereby ensuring the stability of the business process operation.

[0151] When a fault occurs in the access segment, the second communication port corresponding to the faulty first communication port can be located from the first access link. If there is at least one day in which the second communication port has not failed, normal business information for the target business process is generated. If all second communication ports have failed and at least one communication port of the associated access network element in the second access link has not failed, normal business information for the target business process is generated. If all second communication ports have failed and all communication ports of the associated access network element in the second access link have failed, abnormal business information for characterizing abnormal access links is generated. For example, referring to Figure 6 , shows a schematic diagram of the access segment detection process provided in an embodiment of the present invention. When the access network element aBAC1-aPort1 fault alarm is generated, the device type and service process can be determined to determine the corresponding target service process. Assuming it is a VOBB process, the communication link calculation can be performed to obtain the corresponding communication link (such as Figure 2As shown) and the communication link is judged. If aPort3 in link group 1 has no fault, it indicates that the business process is not affected, and the access network element aBAC1 can communicate data through aPort3, then the corresponding business normal information is generated; if aPort3 fails, the access network element aBAC2 that is paired with the access network element aBAC1 is obtained, and its corresponding link group 2 is obtained. When aPort5 and aPort7 both fail, it indicates that the link of the protection group has also failed and the business process cannot be continued, then the business abnormality information is generated; if only one of aPort5 and aPort7 fails, or both do not fail, then the corresponding business normal information is generated, thereby determining whether the business process has failed by detecting the communication link. On the one hand, it realizes the rapid detection of the business process status. On the other hand, by detecting the communication status of the communication link, it can locate the faulty network element and realize the rapid location of the fault cause, so that maintenance personnel can perform maintenance in time, thereby ensuring the stability of the business process operation.

[0152] When a fault occurs in a core network element, if the shutdown list is not empty, it indicates that there are relevant communication links in the core network that can carry out data communication, and then normal business information for the target business process is generated; if the shutdown list is empty, it indicates that all communication links in the core network have failed, and then business abnormality information is generated to characterize the abnormality of the core network element. By detecting the communication link, it is determined whether the business process has failed. On the one hand, it realizes the rapid detection of the business process status. On the other hand, by detecting the communication status of the communication link, it can locate the faulty network element and realize the rapid location of the fault cause so that maintenance personnel can perform maintenance in time, thereby ensuring the stability of the business process operation.

[0153] It should be noted that the embodiments of the present invention include but are not limited to the above examples. It is understandable that those skilled in the art can also make settings according to actual needs under the guidance of the ideas of the embodiments of the present invention, and the present invention does not limit this.

[0154] In an embodiment of the present invention, applied to a data communication network, during a data communication process, if a fault is detected in the data communication network, the target network element where the fault occurs can be located, a target service process corresponding to the target network element can be determined, and a target protection relationship model corresponding to the target service process can be obtained. Then, based on the target protection relationship model, a target service communication link corresponding to the target service process can be calculated from the data communication network. The target service communication link includes mutual access paths between different network elements. Then, based on each mutual access path, it is determined whether the target service communication link is abnormal, and a service detection result for the target service process is generated. The service detection result includes one of normal service information and abnormal service information. Therefore, for the data communication network, by constructing a protection relationship model corresponding to the service process, during the data communication process, when a network element fails, the communication link corresponding to the service process can be calculated based on the protection relationship model, and the communication link can be detected to determine whether the service process has failed. On the one hand, rapid detection of the service process status is achieved. On the other hand, by detecting the communication status of the communication link, the faulty network element can be located, and the cause of the failure can be quickly located, so that maintenance personnel can perform maintenance in a timely manner, thereby ensuring the stability of the service process operation.

[0155] In order to help those skilled in the art better understand the technical solutions of the embodiments of the present invention, an example is given below to illustrate:

[0156] For broadband call services, the VoBB service process can be divided into VoBB registration process, VoBB calling process, VoBB called process, VoBB calling process to another network, and another network calling VoBB process. Specifically, taking the VoBB registration process as an example, it can include several communication processes, refer to Figure 7, which shows a schematic diagram of the registration process provided in an embodiment of the present invention. The VoBB registration process may include nine processes: BAC (Border Access Controller) to P-CSCF (Proxy-Call Session Control Function), P-CSCF to I-CSCF (Interrogating-Call Session Control Function), I-CSCF to ENUM / D (Telephone Number Mapping Working Group), I-CSCF to ENUM / D to HSS (Home Subscriber Server), I-CSCF to ENUM / D to HSS to S-CSCF (Service-Call Session Control Function), S-CSCF to HSS, S-CSCF to MMTEL (MultiMedia Telephony), and MMTEL to HSS.

[0157] Specifically, taking P-CSCF accessing I-CSCF as an example, the automatic path calculation model and protection relationship model of this step are constructed, such as Figure 8 As shown, a schematic diagram of the protection relationship model provided in an embodiment of the present invention is shown, which includes the link group, protection group, network element association relationship, etc. involved in the process of P-CSCF accessing I-CSCF. Through automatic path calculation and protection relationship model, the calculation and presentation of the complete service path between network elements can be performed, such as Figure 9 The figure shows a schematic diagram of the communication links provided in an embodiment of the present invention, including the links involved in the process of a single P-CSCF accessing a single I-CSCF. When a link in the normal network path is interrupted, recalculation can be performed to confirm whether there is still an accessible path for the service, thereby determining whether the service process is interrupted. When a link group interruption is detected, automatic path calculation is initiated, calculating each step in the entire VoBB service process, and determining whether the terminal link affects other processes in the service process. If so, the affected process is prompted, thereby providing a service impact judgment. By sequentially determining the network element inter-access relationship of each step in each service process, the service impact of the entire process can be determined.

[0158] Reference Figure 10, shows a schematic diagram of the detection process of the business process provided in the embodiment of the present invention. When a network fault alarm occurs, it can be judged by the device type and the business type, and whether the network element inter-access relationship of each step in each business process is normal can be judged in turn. For example, first judge the business process 1. If it is normal, then enter the judgment of business process 2. If business process 2 is also normal, then enter the next business process, until all business processes are judged. In this process, if a certain business process is damaged, the business abnormality information can be output. Among them, assuming that when judging business process 1, if the fault occurs in the network element access section, it can be judged whether the link group is normal. If it is normal, the normal information of business process 1 is output; if the link group is abnormal, it is judged whether the corresponding protection group is normal. If it is normal, the normal information of business process 1 is output; if the protection group is abnormal, the abnormal information of business process 1 is output. If the fault occurs in the core bearer segment, it is determined whether the link group is normal. If it is normal, the information that business process 1 is normal is output; if the link group is abnormal, it is calculated whether there is any available path. If there is an available path, the information that business process 1 is normal is output; if there is no available path, the information that business process 1 is abnormal is output. Therefore, for a single business process, the communication link can be tested to determine whether the business process has a fault. On the one hand, it realizes the rapid detection of the business process status. On the other hand, by detecting the communication status of the communication link, it can locate the faulty network element and realize the rapid location of the fault cause, so that maintenance personnel can perform maintenance in time, thereby ensuring the stability of the business process operation.

[0210] The audio output unit 1203 can convert audio data received by the RF unit 1201 or the network module 1202 or stored in the memory 1209 into an audio signal and output it as sound. In addition, the audio output unit 1203 can also provide audio output related to a specific function performed by the electronic device 1200 (for example, a call signal reception sound, a message reception sound, etc.). The audio output unit 1203 includes a speaker, a buzzer, a receiver, etc.

[0211] The input unit 1204 is used to receive audio or video signals. It may include a graphics processing unit (GPU) 12041 and a microphone 12042. The GPU 12041 processes image data, such as still images or videos, captured by an image capture device (e.g., a camera) in video capture mode or image capture mode. The processed image frames may be displayed on the display unit 1206. Image frames processed by the GPU 12041 may be stored in the memory 1209 (or other storage medium) or transmitted via the RF unit 1201 or the network module 1202. The microphone 12042 may receive sound and process it into audio data. In phone call mode, the processed audio data may be converted into a format that can be transmitted to a mobile communication base station via the RF unit 1201.

[0212] Electronic device 1200 also includes at least one sensor 1205, such as a light sensor, a motion sensor, or other sensors. Specifically, the light sensor includes an ambient light sensor and a proximity sensor. The ambient light sensor can adjust the brightness of display panel 12061 based on the brightness of the ambient light, and the proximity sensor can turn off display panel 12061 and / or the backlight when electronic device 1200 is brought to the ear. An accelerometer, a type of motion sensor, can detect acceleration in all directions (generally three axes) and, when stationary, can detect the magnitude and direction of gravity.

Specifically, the user input unit 1207 includes a touch panel 12071 and other input devices 12072. The touch panel 12071, also known as a touch screen, can detect user touch operations on or near it (for example, operations performed on or near the touch panel 12071 using a finger, stylus, or any other suitable object or accessory). The touch panel 12071 may include two components: a touch detection device and a touch controller. The touch detection device detects the user's touch position and detects signals generated by the touch operation, transmitting the signals to the touch controller. The touch controller receives the touch information from the touch detection device, converts it into touch point coordinates, and then sends it to the processor 1210, which receives and executes commands from the processor 1210.

[0215] Furthermore, the touch panel 12071 may be overlaid on the display panel 12061. When the touch panel 12071 detects a touch operation on or near the touch panel 12071, the touch operation is transmitted to the processor 1210 to determine the type of touch event. The processor 1210 then provides a corresponding visual output on the display panel 12061 based on the type of touch event. It will be understood that in one embodiment, the touch panel 12071 and the display panel 12061 are two independent components to implement the input and output functions of the electronic device. However, in some embodiments, the touch panel 12071 and the display panel 12061 may be integrated to implement the input and output functions of the electronic device.

The processor 1210 may include one or more processing units; preferably, the processor 1210 may integrate an application processor and a modem processor. The application processor primarily processes the operating system, user interface, and application programs, while the modem processor primarily handles wireless communications. It is understood that the modem processor may not be integrated into the processor 1210.

[0219] The electronic device 1200 may further include a power supply 1211 (such as a battery) for supplying power to various components.
