Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The invention provides a method and a device for determining a board card mode, aiming at the problem that when SYSIIC on an LTE side and an NR side are started simultaneously, SYSIIC conflict occurs to cause that hardware cannot be started.
As shown in fig. 1, a board mode determining method according to an embodiment of the present invention is applied to a first device in a first network mode, and includes:
step 101, after interacting a board planning notification with a second device in a second network mode, starting a first timer by the first device;
it should be noted that one of the first network mode and the second network mode is a Long Term Evolution (LTE) network mode, the other is a new air interface (NR) network mode, and the first apparatus and the second apparatus are devices (modules) belonging to different network modes under the same base station.
After the first device and the second device interact with board planning notification (also referred to as board planning information), the first device and the second device can know the board state of the other side, and the board mode of the first device is already in a dual-mode; and then, the first device starts a first timer, where it needs to be noted that the first timer is a heartbeat timeout timer, specifically, the timing duration of the first timer is usually set to 30 seconds, and the first device monitors whether a heartbeat response message fed back by the second device is received during the operation of the first timer.
Step 102, judging whether a heartbeat response message of a second device is received before a first timer is overtime;
step 103, if the heartbeat response message is not received, determining whether a common mode negotiation response sent by the second device is received;
and 104, if the common mode negotiation response is not received, switching the board card mode of the first device from a dual-mode to a single-mode.
It should be noted that before the first timer times out, if the first device does not receive the heartbeat response message fed back by the second device, it indicates that the board of the second device may not be in place, at this time, the common mode negotiation response fed back by the second device needs to be obtained, if the second device does not send the common mode negotiation response, it indicates that the second device cannot operate, the board state of the first device cannot be maintained in the dual mode any more, at this time, the mode needs to be switched, and the board state is switched to the single mode, which indicates that the base station can only operate in one network mode at this time.
It should be further noted that, if the first device receives the heartbeat response message fed back by the second device, which indicates that the board card of the second base station is still in place, the first device resets the first timer, and continues to monitor the heartbeat response message.
It should be noted that, before feeding back the common mode negotiation response, the second device needs to receive the common mode negotiation request sent by the first device, and the second device performs feedback of the common mode negotiation response according to the common mode negotiation request. If the first base station receives the common mode negotiation response fed back by the second device after sending the common mode negotiation request to the second device, the fact that the board card of the second device is still in place is indicated, the first device resets the first timer, and monitoring of the heartbeat response message is continued.
It should be noted that, the second device also needs to execute the same process as the first device, and in this implementation manner, even if one side enters the single mode due to misjudgment, the other side also executes the same process, and when the other side does not enter the single mode, the common mode base station does not enter the single mode, so that the problem that the common mode base station becomes the single mode and cannot be recovered can be avoided; meanwhile, when one of the first device and the second device is abnormal, the base station cannot enter a dual-mode (namely a common mode), and the abnormal protection can be effectively carried out.
The following describes a specific implementation of an embodiment of the present invention in practical application.
In the first situation, when the LTE side main control board is started earlier than the NR side main control board, a pair board detection flow is added when the main control board is started, a 10s negotiation timer is created, the LTE side sends a common mode negotiation request to the pair board every 10s, and if a pair board common mode negotiation response is received, the local board sysic is closed, and the NR side main control board opens the sysic. If there is no response for 3 consecutive times, the dual-mode negotiation request is initiated again, if there is a common-mode negotiation response, the heartbeat timeout timer is reset for 30s, if there is no response, the heartbeat timeout timer is set to a single mode, the sysic is opened, and specifically, the implementation flow is as shown in fig. 2:
step 201, the LTE side main control board is started first, and a Device Drive (DD) interface is called to query the board-to-board status through an Erasable Programmable Logic Device (EPLD);
step 202, judging whether the board hardware is in place, if so, executing step 203, and if not, executing step 219;
step 203, establishing a 30s timeout timer and a 10s negotiation period timer;
a common mode negotiation request is periodically transmitted to the NR-side device as instructed by the 10s negotiation period timer.
Step 204, after the timeout timer of 30s times out, a single mode mark is set, and SYSIIC is opened;
step 205, the NR side main control board is started, and the DD interface is called to inquire the board state through the EPLD;
step 206, judging whether the board hardware is in place, if so, executing step 207, and if not, executing step 225;
step 207, a 30s timeout timer is created, and a 10s negotiation period timer is created;
step 208, sending a common mode negotiation request to the LTE side device;

step 215, reset the 30s heartbeat timeout timer;
step 216, sending a common mode negotiation request to the NR side;
step 217, receiving a common mode negotiation response fed back by the NR side;
step 218, determining whether a common mode negotiation response is received, if so, performing step 215, and if not, performing step 219;
step 219, setting a single mode flag, and opening SYSIIC;
step 220, for the NR side, determining whether a heartbeat response is received within 30s, if so, performing step 221, and if not, performing step 222;
step 221, resetting a 30s heartbeat timeout timer;
step 222, sending a common mode negotiation request to an LTE side;
step 223, receiving a common mode negotiation response fed back by the LTE side;
step 224, determining whether a common mode negotiation response is received, if so, performing step 221, and if not, performing step 225;
step 225, set single mode flag, turn on sysic.
It should be particularly noted that, in the above specific implementation process, there is no explicit implementation time sequence between step 214 to step 219 and step 220 to step 225, and the implementation process of the NR side and the implementation process of the LTE side are not affected by each other.
And in the second situation, when the NR side main control board is started earlier than the LTE side main control board, a pair board detection flow is added when the main control board is started, a 10s negotiation timer is established, the NR side sends a common mode negotiation request to the pair board every 10s, and if a response to the pair board common mode negotiation is received, the LTE side main control board closes SYSIIC, and the NR still provides SYSIIC. If no response is made for 3 consecutive times, initiating the dual-mode negotiation request again, if there is a common-mode negotiation response, resetting the 30s heartbeat timeout timer, if there is no response, setting the heartbeat timeout timer to a single mode, and opening the sysic, specifically, the implementation flow is as shown in fig. 3:
step 301, the NR side main control board is started first, and the DD interface is called to query the board state through the EPLD;
step 302, judging whether the board hardware is in place, if so, executing step 303, and if not, executing step 325;

step 309, the NR side device feeds back a common mode negotiation response to the LTE side device;
step 310, the NR side is modified into a dual-mode, the LTE side sets a dual-mode mark, and a negotiation timer is deleted;
at this time, sysic is still controlled by the NR side.
311, the NR side and the LTE side interact with the board planning information;
step 312, a 30s heartbeat timeout timer and a 10s heartbeat cycle timer are created on the NR side, and a 30s heartbeat timeout timer and a 10s heartbeat cycle timer are created on the LTE side;

step 316, sending a common mode negotiation request to the NR side;
step 317, receiving a common mode negotiation response fed back by the NR side;
