Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for switching inter-board rates.
Background
With the development of communication technology, an existing wireless communication base station mainly comprises a main control board and one or more baseband boards, wherein the main control board comprises a main board and a slave board, the main board is used for interacting with a management station and managing Operation and Maintenance (OM) resources and wireless resources of the base station, and the slave board is used for being responsible for wireless resource interaction. The path between the master and slave boards is opened by default to ensure communication between the master and slave boards. And the paths between the main control board and all the baseband boards are opened, and the paths between the main control board and all the baseband boards are closed by the slave boards so as to ensure that no loop is generated between the main control board and the baseband boards.
Referring to fig. 1, the main control board is composed of an OM unit and a radio resource management unit. The OM unit is used for managing and scheduling various resources in the base station, including initialization, initial value configuration, board management, dynamic configuration, performance management, fault management, software management, monitoring management, frame number calibration, tracking management, file management, database management, and the like. And the radio resource management unit is used for managing the radio resources. The baseband board is composed of an OM unit and a baseband processing unit. The baseband processing unit is mainly used for processing baseband signals through a physical layer algorithm and an MAC algorithm.
A wireless communication base station can Access services of Multiple systems, such as Wideband Code Division Multiple Access (WCDMA), Time Division-Synchronous Code Division Multiple Access (TDSCDMA), Code Division Multiple Access (CDMA), Time Division Long Term Evolution (LTE-TDD), and Frequency Division Long Term Evolution (LTE-FDD).
For example, referring to fig. 2, in the same wireless communication base station, service data of a standard a is transmitted by a master board a and a baseband board a, and service data of a standard B is transmitted by a slave board B, the master board a, and the baseband board B, that is, a service transmitted by the slave board B needs to pass through the master board a to be transmitted with the baseband board B.
In the prior art, the service requirements are continuously improved, and the requirements on the processing capacity and the transmission capacity of service data of the base station are correspondingly improved, so that equipment manufacturers develop a novel main control board and a novel baseband board which are high in data processing capacity and high in data transmission speed. However, since the slave board B and the baseband board B cannot be directly connected to each other, and the service data of the standard B needs to be transmitted through the master board a, the actual transmission rate is limited by the transmission rate between the master board a and the slave board B and also by the transmission rate between the master board a and the baseband board B, and if any one of the master control board and the baseband board does not support high-speed transmission, high-speed transmission cannot be performed. Obviously, if it is desired to expand the service of the standard B, not only the slave board B and the baseband board B need to use the new slave board B and the new baseband board, but also the motherboard a needs to use the new motherboard a to support high-speed transmission, which may consume a large amount of equipment cost, and increase the difficulty of maintenance.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the 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 invention.
In order to save the cost of equipment, reduce the difficulty of maintenance and reduce the influence on the existing service when realizing high-speed transmission, the embodiment of the invention designs an inter-board rate switching method.
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
In the embodiment of the invention, the base station at least comprises a main board and a baseband board, and in order to improve the transmission rate, the base station adopts the baseband board provided with the isolating device, wherein the isolating device is used for isolating the communication between the main board and the slave board through the baseband board, so that the communication loop between the main board baseband board and the slave board cannot be caused by the passage between the slave board and the baseband board. When the transmission board is connected to the main board to perform inter-board rate switching, different modes can be respectively adopted to realize inter-board rate switching according to different types of the transmission board.
For example, when the transmission board is a baseband board, the rate switching between boards can be realized in a first mode; and when the transmission plate is a slave plate, the inter-plate rate switching is carried out by adopting a second mode.
The above two modes will be described in detail in the following with specific procedures.
Referring to fig. 3, when the transmission board is a baseband board, the specific process of implementing inter-board rate switching by the first method is as follows:
step 300: and the baseband board sends a rate switching request message to the main board.
In practical applications, when step 300 is executed, the rate switch request message at least includes identification information, and optionally, the identification information may be an identification code of the device or a serial number.
Step 301: the main board determines a target switching board and a target switching rate.
In practical application, the main board obtains a first highest transmission rate of the locally stored main board, determines a second highest transmission rate corresponding to the identification information based on the identification information, and determines that the target switching board is the main board and the baseband board when determining that a lowest value of the first highest transmission rate and the second highest transmission rate is higher than a preset rate, and the target switching rate is the lowest value of the first highest transmission rate and the second highest transmission rate.
Thus, the main board can determine the highest transmission rate supported by the main board and the baseband board.
Further, if the main board determines that the target switching rate is not higher than the preset rate, step 306 is executed.
Step 302: the mainboard switches the local transmission rate to the target switching rate.
Step 303: the main board sends a switching instruction to the baseband board.
Step 304: the baseband board switches the transmission rate to a target switching rate.
In practical application, after the baseband board receives a switching instruction sent by the main board, when the preset time delay is determined to be reached, the transmission rate is switched to the target switching rate.
Therefore, the switching result can be sent to the mainboard after the mainboard is switched to the target switching speed through the preset time delay, and the problem that the mainboard cannot receive the switching result in the switching process is avoided.
Step 305: the baseband board returns the switching result to the main board.
In practical application, when the baseband board determines that the preset time point is reached, the switching result is returned to the main board.
Step 306: the motherboard determines that the switch is initially complete.
In practical application, the main board determines that the switching is primarily completed when determining that the switching is successful based on the received switching result.
Further, the main board reports a switching abnormal result and terminates the switching process when determining that the switching fails based on the received switching result.
Step 307: the master board determines the presence of the slave board.
In practical application, when step 307 is executed, further, if the master board determines that no slave board exists, the switching process is terminated, and it is determined that the switching is completely finished.
Step 308: the motherboard determines a switching adjustment rate.
In practical application, the master board obtains the third highest transmission rate of the slave board, and determines that the switching adjustment rate is the lowest value of the third highest transmission rate and the highest transmission rate of the baseband board when the lowest value of the third highest transmission rate and the highest transmission rate of the baseband board is higher than the preset rate.
Further, if it is determined that the lowest value of the third highest transmission rate and the highest transmission rate of the baseband board is not higher than the preset rate, the main board determines that the switching is not required, and performs step 314.
Thus, the master board can determine the highest transmission rate that is commonly supported between the baseband board and the slave board.
Step 309: the master board sends switching instructions to the baseband board and the slave board respectively.
Step 310: the baseband board switches the transmission rate to the switching adjustment rate.
Step 311: and the slave board opens a communication path with the baseband board and switches the transmission rate to the switching regulation rate.
In practical application, when step 311 is executed, the communication paths between the master board and the baseband board and between the master board and the slave board are opened, and to avoid a communication loop, the communication path between the slave board and the baseband board is closed by default, and when the highest transmission rate of the baseband board is higher than a preset rate, it indicates that the baseband board is a novel baseband board, that is, an isolation device is arranged in the baseband board, so that the problem of the communication loop can be avoided, and thus, the communication path between the slave board and the baseband board is opened, and direct information transmission between the slave board and the baseband board can be realized.
Step 312: the master board receives the switching results returned by the baseband board and the slave board respectively.
Step 313: the motherboard determines that the switch is complete.
In practical application, the main board determines that the switching is completed when the switching of the base band board and the slave board is successful based on the switching result, otherwise, the switching abnormal result is reported.
Step 314: the master board sends switching response messages to the baseband board and the slave board respectively.
In practical application, the master board sends switching response messages to the baseband board and the slave board respectively, if the baseband board and the slave board receive the switching response messages representing successful switching, the switching is determined to be completed, otherwise, the switching is determined not to be needed.
Further, when the baseband board is disconnected from the main board, the main board determines the transmission rate between the baseband board and the main board, and whether the transmission rates of the slave boards are both preset rates, if yes, the disconnection is determined to be completed, otherwise, the local transmission rate is switched to the preset rate, a switching instruction is sent to the slave boards, then the slave boards switch the transmission rate to the preset rate based on the switching instruction, and the switching result is returned to the main board, further, the main board determines that the disconnection switching is completed if the switching is determined to be successful based on the switching result, otherwise, abnormal switching results are reported.
Referring to fig. 4, when the transmission board is a slave board, the specific flow of implementing inter-board rate switching by the second method is as follows:
step 400: and sending a rate switching request message from the slave board to the master board.
In practical applications, when step 400 is executed, the rate switch request message at least includes identification information, and optionally, the identification information may be an identification code of the device or a serial number.
Step 401: the main board determines a target switching board and a target switching rate.
In practical application, the main board obtains the highest transmission rate of each baseband board, and determines a third highest transmission rate corresponding to the identification information based on the identification information.
When the main board determines that the lowest value of the highest transmission rate and the third highest transmission rate of one baseband board is higher than the preset rate, the main board respectively determines that the target switching board is the slave board and each baseband board with the lowest value of the highest transmission rate and the third highest transmission rate higher than the preset rate;
the main board determines a target switching rate corresponding to each target switchboard, wherein the target switching rate corresponding to one target switchboard is the lowest value of the highest transmission rate and the third highest transmission rate of one target switchboard.
The slave board and each baseband board have corresponding rate switching slots, so that the communication between the slave board and each baseband board is independent and does not affect each other, and therefore, the corresponding target switching rate is different for each target switching board.
For example, if there are 3 slots, slot a, slot B, and slot C in the slave board, and the corresponding baseband boards are baseband board a, baseband board B, and baseband board C, respectively, the preset rate is 100Mb/s, the third highest transmission rate of the slave board is 1024Mb/s, the highest transmission rate of baseband board a is 100Mb/s, the highest transmission rate of baseband board B is 512Mb/s, and the highest transmission rate of baseband board C is 800Mb/s, the master board determines that the target switching board is slave board, baseband board B, and baseband board C, and the target switching rate for baseband board B is 512Mb/s, the target switching rate for baseband board C is 800Mb/s, the target switching rate for slot B in the slave board is 512Mb/s, and the target switching rate for slot C is 800 Mb/s.
Further, if the main board determines that the target switching rate is not higher than the preset rate, step 407 is executed.
Step 402: the master board sends a switching instruction to the slave board and each target switching board respectively.
Step 403: the baseband board switches the transmission rate to a target switching rate.
Step 404: and switching the transmission rate to the target switching rate from the plate.
Step 405: the main board receives the switching results returned by the target switching boards respectively.
In practical application, when each target switching board, namely the corresponding baseband board and slave board, determines to reach the preset time point, the switching result is returned to the master board.
Step 406: the motherboard determines that the switch is complete.
In practical application, the main board determines that the switching is completed when determining that the switching is successful based on the received switching result.
Further, the main board reports a switching abnormal result and terminates the switching process when determining that the switching fails based on the received switching result.
Step 407: the main board sends a switching response message to each target switching board.
In practical application, when step 407 is executed, the baseband board and slave board corresponding to each target handover board receive the handover response message, and determine that the handover is completed.
Further, when the slave board is disconnected from the master board, the master board sequentially determines whether the transmission rate of each baseband board is a preset rate, if so, the disconnection is determined to be completed, otherwise, a switching instruction is respectively sent to each baseband board, then, each baseband board switches the transmission rate to the preset rate based on the switching instruction, and returns a switching result to the master board.
