Description

Technical Field

[0001] The present invention relates to the technical field of repeater stations, and in particular to a repeater station equipment upgrading method and a repeater station system. Background Art

[0002] With the rapid development of my country's mobile communications, various types of repeaters have become an important part of network construction. After the deployment of many repeater equipment, operators manage various repeater equipment through the repeater network management (referred to as network management or network management system). At present, operators generally use the MCP (Monitoring Control Protocol) protocol to monitor and manage repeater equipment. The network management southbound interface monitoring function can be implemented using MCP: A and MCP: C, while the remote upgrade of equipment software generally uses MCP: B. When using the MCP: B method to upgrade, the monitoring software operation mode is divided into two types: monitoring mode and software upgrade mode, such as Figure 1 shown.

[0003] In monitoring mode, the equipment monitoring software normally collects various configuration data of the equipment and reports the generated alarms according to the settings. In this mode, the repeater equipment only uses the MCP: A or MCP: C protocol. The network management sends a "switch to software upgrade mode" command to the repeater equipment to make the repeater equipment enter the software upgrade mode to realize the remote upgrade function.

[0004] In software upgrade mode, the monitoring software of the repeater equipment stops the collection and alarm functions, and performs file transfer and storage. In this mode, the repeater equipment only uses the MCP: B protocol. When the software upgrade is completed, or an error occurs during the software upgrade and the upgrade cannot be completed normally, the repeater equipment can enter the monitoring mode by automatically resetting the software.

[0005] The existing technical solutions have the following disadvantages: 1. When using the MCP:B protocol for upgrading, the upgrade phases are not divided, which makes it inconvenient for users to understand the overall progress of the upgrade.

[0006] 2. When the network manager transmits the upgrade file to the repeater, it takes a long time and the network manager does not provide an intuitive transmission progress value, which makes it inconvenient for users to understand the transmission progress. It is impossible to plan time to handle the upgrade plan of other repeaters. Summary of the invention

[0007] The technical problem to be solved by the embodiments of the present invention is to provide a method for upgrading a repeater device of a repeater system and a repeater system, so that a user can understand the overall upgrade progress in real time.

[0008] In order to solve the above technical problems, an embodiment of the present invention proposes a method for upgrading a repeater device of a repeater system, wherein the system includes a network management and a repeater device, and the method includes: Notification steps: When the network administrator needs to upgrade the repeater equipment, he notifies the repeater equipment to switch the monitoring software operation mode to the software upgrade mode; the repeater equipment switches the operation mode to the software upgrade mode and responds to the network administrator; Transmission steps: The network manager divides the upgrade file into pieces and transmits them to the repeater device. During the transmission process, the network manager calculates and displays the real-time progress of the transmission of the upgrade file. After the transmission is completed, the network manager sends a message to the repeater device that the transmission of the upgrade file has ended; the repeater device responds to the network manager's message that the transmission of the upgrade file has ended, and switches the operating mode to the monitoring mode; Upgrade steps: The repeater equipment installs the updated software according to the upgrade file and restarts, and then informs the network management of the latest version information and upgrade success status; the network management responds to the received version information and ends the upgrade process.

[0009] Accordingly, an embodiment of the present invention further provides a repeater system, including a network management and a repeater device. When the network management needs to upgrade the repeater device, the repeater device is notified to switch the monitoring software operation mode to the software upgrade mode; the repeater device switches the operation mode to the software upgrade mode and responds to the network management; The network manager divides the upgrade file into pieces and transmits them to the repeater device. During the transmission process, the network manager calculates and displays the real-time progress of the transmission of the upgrade file. After the transmission is completed, the network manager sends a message to the repeater device that the transmission of the upgrade file has ended. The repeater device responds to the network manager's message that the transmission of the upgrade file has ended and switches the operating mode to the monitoring mode. The repeater equipment installs the updated software according to the upgrade file and restarts, and then informs the network management of the latest version information and the upgrade success status; the network management responds to the received version information and ends the upgrade process.

[0010] The beneficial effects of the present invention are as follows: when the repeater is upgraded using the MCP:B method, the present invention divides the upgrade phases to facilitate distinguishing the progress of the upgrade process; the present invention can display the upgrade file transmission progress, which is convenient for users to grasp the upgrade time and plan the upgrade schedule.

If the specific posture changes, the directional indication will also change accordingly.

[0019] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0020] Please refer to Figure 6 The method for upgrading the repeater equipment of the repeater system of the embodiment of the present invention includes a preparation step, a notification step, a transmission step, and an upgrading step.

[0021] Preparation steps: The repeater equipment sends heartbeat messages to the network management system several times in succession, and records the timestamp of the start of each heartbeat message sending. The sending interval is the reporting period of the heartbeat message. When the network management receives the heartbeat message sent by the repeater device, it responds and sends a heartbeat response message to the repeater device; The repeater device receives the heartbeat response message and records the corresponding timestamp, and then calculates the transmission delay; The network manager sends a query to the repeater device for the communication parameters of the remote upgrade. After the repeater device responds to the network manager, the network manager parses and saves the communication parameters of the remote upgrade. The communication parameters of the remote upgrade include: monitoring software operation mode, MCP:B interaction mechanism, device response timeout, mode conversion time, device remote upgrade method, continuous transmission coefficient, sending interval time and transmission delay; the repeater device responds to the communication parameter information of the remote upgrade, and the network manager selects the corresponding upgrade file after receiving the response.

[0022] As an implementation method, the repeater equipment calculates the transmission delay Td according to the following formula: Td = ((T1'-T1) + (T2'-T2) +......+(Tn'-Tn)) / n; Wherein, n is the number of heartbeat messages sent by the repeater device to the network management, T1, T2, ... Tn are the timestamps of the start of sending each heartbeat message, and T1', T2', ... Tn' are the timestamps of received heartbeat response messages.

[0023] Notification steps: When the network manager needs to upgrade the repeater equipment, he notifies the repeater equipment to switch the monitoring software operation mode to the software upgrade mode; the repeater equipment switches the operation mode to the software upgrade mode and responds to the network manager. The network manager waits for T T (mode switching time), prepare to enter the next stage.

[0024] Transmission steps: The network manager sends a message to the repeater device to start transmitting the upgrade file. The repeater device responds to the network manager and is ready to receive the upgrade file. The network manager segments the upgrade file and transmits it to the repeater device. During the transmission process, the network manager calculates and displays the real-time progress of the transmission of the upgrade file. After the transmission is completed, the network manager sends a message to the repeater device to end the transmission of the upgrade file. The repeater device responds to the network manager's message to end the transmission of the upgrade file and switches the operation mode to the monitoring mode.

[0025] As an implementation method, if the interaction mechanism of the MCP:B protocol used by the network manager to upgrade the repeater equipment is 0 (indicating that each packet confirmation method is adopted. That is, each received packet is confirmed once, and the mechanism of continuously sending NC packets and waiting for a response), the network manager calculates the real-time progress P according to the following formula: ; If the interactive mechanism of the MCP:B protocol used by the network manager to upgrade the repeater equipment is 1 (indicating that a multiple-question-one-answer method is used. That is, a mechanism in which each NC packet is confirmed once and NC packets are continuously sent before waiting for a response), the network manager calculates the real-time progress P according to the following formula: ; Among them, Index is the packet number when the packet is transmitted, starting from 1; C is the number of fragments, is the sending interval, NC is the continuous sending coefficient, For transmission delay.

[0026] The network management displays the progress P value to the front-end page in real time, so that users can understand the progress of the upgrade file transfer in real time.

[0027] The network management uses the MCP:B protocol to transmit the maximum message size E at a time based on the size S of the upgrade file.len The calculation formula for the number of shards C is: C = S / E len ; Where, if S is divided by E len If there is a remainder, an additional fragment needs to be transmitted.

[0028] Upgrade steps: The repeater equipment installs the updated software according to the upgrade file and restarts, and then informs the network management of the latest version information and upgrade success status; the network management responds to the received version information and ends the upgrade process.

[0029] The repeater system of the embodiment of the present invention includes a network management and repeater equipment.

[0030] The repeater equipment continuously sends heartbeat messages to the network management for several times, and records the timestamp of the start of each heartbeat message sending. The sending interval is the reporting period of the heartbeat message. When the network management receives the heartbeat message sent by the repeater device, it responds and sends a heartbeat response message to the repeater device; The repeater device receives the heartbeat response message and records the corresponding timestamp, and then calculates the transmission delay; The network manager sends a query to the repeater device for the communication parameters of the remote upgrade. After the repeater device responds to the network manager, the network manager parses and saves the communication parameters of the remote upgrade. The communication parameters of the remote upgrade include: monitoring software operation mode, MCP:B interaction mechanism, device response timeout, mode conversion time, device remote upgrade method, continuous transmission coefficient, sending interval time and transmission delay; the repeater device responds to the communication parameter information of the remote upgrade, and the network manager selects the corresponding upgrade file after receiving the response.

[0031] When the network administrator needs to upgrade the repeater equipment, he notifies the repeater equipment to switch the monitoring software operation mode to the software upgrade mode; the repeater equipment switches the operation mode to the software upgrade mode and responds to the network administrator; The network manager divides the upgrade file into pieces and transmits them to the repeater device. During the transmission process, the network manager calculates and displays the real-time progress of the transmission of the upgrade file. After the transmission is completed, the network manager sends a message to the repeater device that the transmission of the upgrade file has ended. The repeater device responds to the network manager's message that the transmission of the upgrade file has ended and switches the operating mode to the monitoring mode. The repeater equipment installs the updated software according to the upgrade file and restarts, and then informs the network management of the latest version information and the upgrade success status; the network management responds to the received version information and ends the upgrade process.

[0032] Example 1: Figure 2 As shown, the process of the repeater system in the upgrade preparation stage of the embodiment of the present invention is as follows: 1. The repeater device sends three heartbeat messages to the network management system in succession. The interval between the heartbeat messages is the heartbeat reporting period. The repeater device records the timestamps T1, T2 and T3 of the start of the three heartbeat messages.

[0033] 2. The network management system responds to three heartbeat messages.

[0034] 3. The repeater device calculates the transmission delay Td. Furthermore, after receiving three consecutive heartbeat messages, the repeater device records the corresponding timestamps T1', T2' and T3', and calculates the transmission delay Td = ((T1'-T1) + (T2'-T2) +(T3'-T3)) / 3, which is the average transmission delay.

[0035] 4. The network manager sends a query to the repeater device for the communication parameters of the remote upgrade. After the repeater device responds to the network manager, the network manager parses and saves the communication parameters of the remote upgrade. The communication parameters of the remote upgrade include: monitoring software operation mode, MCP:B interaction mechanism, device response timeout (T OT1 ), mode conversion time (T T ), device remote upgrade mode, continuous transmission coefficient (NC), transmission interval (Tg) (this data is meaningful only when NC>1) and transmission delay Td. The meaning of remote upgrade communication parameters is shown in Table 1:

[0036] 5. The repeater equipment responds to the communication parameters for remote upgrade.

[0037] 6. The network administrator notifies the repeater equipment to switch the monitoring software operation mode to software upgrade mode.

[0038] 7. The repeater equipment switches the monitoring software operation mode to software upgrade mode and responds to the network administrator.

[0039] 8. Network manager waits for T T (mode switching time), prepare to enter the next stage.

[0040] like Figure 3 As shown, the process of the repeater system in the embodiment of the present invention in the upgrade transmission file stage is as follows: 1. The network management sends a message to the repeater device to start transmitting the upgrade file.

[0041] 2. The repeater equipment responds to the network administrator and prepares to receive the upgrade file.

[0042] 3. The network manager divides the upgrade file into pieces and transmits them. The number of pieces (C) is the number of times the network manager divides the upgrade file into pieces according to the size of the upgrade package (S) sent and the maximum message size (E) that the network manager can transmit each time using the MCP:B protocol. len), the calculation formula is: C = S / E len + (S % E len > 0)? 1:0). Among them, S / E len The value is an integer, (S % E len > 0 )? 1: 0) means if S is divided by E len If there is a remainder, an additional fragment needs to be transmitted.

[0043] 4. The network manager responds to the upgrade file segment transmission. Further, the network manager repeats the above steps 3 and 4 for C times.

[0044] 5. The network manager sends a message to the repeater device to end the transmission of the upgrade file and switches the monitoring software operation mode to monitoring mode.

[0045] 6. The repeater equipment responds to the network management's message that the upgrade file transmission has ended, and switches the monitoring software operation mode to monitoring mode.

[0046] like Figure 4 As shown, the process of the repeater system in the embodiment of the present invention in the software upgrade phase is as follows: 1. The repeater device installs the updated software and restarts the device. Further, the updated software is an upgrade file in which the network manager transmits the software package to be upgraded to the repeater device during the upgrade file transmission phase. After the repeater device updates the upgrade file, it restarts, and the repeater device completes the software update.

[0047] 2. The repeater equipment notifies the network administrator of the latest version information and upgrade success status.

[0048] 3. The network manager responds to the received version information to end the upgrade process.

[0049] Embodiment 2: According to the interaction mechanism of the repeater, the network manager calculates the real-time progress P of the software transmission: If the MCP:B interaction mechanism is 0, it means that each packet is confirmed once.

[0050] ; Furthermore, Index is the packet sequence number when the sub-packet is transmitted, that is, the number of the fragment of the software package to be upgraded. For example: C = 1000, Index = 10, = 1%. This means that the software package to be upgraded needs to be transferred 1000 times, and the current transfer is the 10th time, with an overall progress of 1%.

[0051] If the MCP:B interaction mechanism is 1, it indicates that a multiple-question-one-answer method is adopted, that is, a confirmation is made once each NC packet is received, and a mechanism is adopted in which NC packets are continuously sent and then a response is waited for.

[0052] ; In the above formula, NC represents the continuous transmission coefficient, Tg represents the sending interval time (this data is meaningful only when NC>1), Td represents the transmission delay, Index is the packet number during packet transmission, and C represents the total number of times the packet is sent, that is, the number of fragments.

[0053] from Figure 5 It can be seen that all software upgrade packages are transmitted in C times, that is, fragments 1 to C will be transmitted in sequence. Among them, each fragment waits for Tg time, and the repeater equipment responds once every NC times, and the response time is a transmission delay Td. Figure 5 It goes through an NC transmission process, which takes time .

[0054] At the Index time, it experienced The NC transmission process is a continuous NC transmission, that is, the repeater responds once. .in, Takes an integer value.

[0055] At the Index time, after removing the complete NC transmission processes mentioned above, the remaining number of transmissions is times, each transmission delay , it takes time .

[0056] At the Index time, the Index-th fragment package has been sent and the process of preparing to send the Index+1th fragment package has begun.

[0057] At the Index time, the time consumed is the sum of the complete NC stage time experienced and the remaining single stage time, that is, .

[0058] The total transmission time, that is, the time consumed when C fragments are transmitted, is .

[0059] Therefore, P is the percentage of the Index-th transmission time / the total transmission time, which is the formula .

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
