Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for identifying and processing a base station fault.
Background
In the prior art, in order to save energy, a small base station (energy saving cell) and a macro base station (compensation cell) are present, an overlapping portion exists between a coverage area of the macro base station and a coverage area of the small base station, and even the coverage area of the macro base station completely includes the coverage area of the small base station, as shown in fig. 1; further, a small cell (energy saving cell) turn-off technology (small cell is turned off, and a macro base station performs compensation) occurs correspondingly, specifically:
the small base station turn-off (or dormancy)/turn-on function refers to that a cell of the small base station and a cell of the macro base station belong to an inclusion relationship, the small base station belongs to capacity enhancement, and in a time period with lower network load, the small base station can be turned off to enter an energy-saving state, so that an energy-saving effect is achieved (the small base station in the dormancy state can be communicated with the macro base station), and when the network load is increased, the macro base station informs the small base station to be turned on to provide normal service.
The small base station in the same system is turned off by the following processes: exchanging resource load information between the small base station and the macro base station, switching a terminal of the small base station to the macro base station, entering an energy-saving state by the small base station and awakening the small base station by the macro base station; the load information exchange between base stations is shown in fig. 2, which mainly involves the following X2 (inter base station interface) messages:
resource Status Request/Resource Status response Resource Status Request/Resource Status Update.
Namely, Resource information exchange by X2 message.
In a preset energy-saving period, through load information exchange between the small base station and the macro base station, when the respective loads of the small base station and the macro base station are found to meet respective small base station turn-off threshold values, if terminals in a connection state still exist on the small base station, the terminals are forcibly switched to the macro base station. When the terminal on the small cell is 0, the small cell enters an energy saving state (the transmission power related to the small cell is turned off), and notifies the basic coverage macro base station and other neighboring macro base stations, and the process is shown in fig. 3 and includes:
step 31 a: the small base station sends a base station configuration update message eNB configuration update to a basic coverage macro base station;
step 31 b: the small base station sends a base station configuration update message eNB configuration update to other neighbor macro base stations;
step 32 a: the basic coverage macro base station feeds back a base station configuration Update response message eNBONfiguration Update Ack to the small base station;
step 32 b: and the macro base stations of other adjacent areas feed back a base station configuration Update response message eNBONfiguration Update Ack to the small base station.
The small base station in the step 31a and the step 31b sends a base station configuration updating message to a macro base station providing basic coverage and other adjacent areas, and informs the macro base station to enter an energy-saving state; step 32a and step 32b provide basic coverage macro base station and other neighbor macro base station send base station configuration update response message to small base station;
when the macro base station load exceeds the preset wake-up threshold value of the small base station shutdown technology, the macro base station sends a message to wake up the small base station in the energy-saving state, and the small base station returns to the normal state, wherein the process is shown in fig. 4 and comprises the following steps:
step 41: a macro base station sends a Cell Activation Request message to a small base station;
and the macro base station sends a cell activation message to the small base station in the energy-saving state to wake up the small base station in the energy-saving state.
Step 42: the small base station feeds back a Cell Activation Response message to the macro base station.
The small base station sends a response message to confirm the receipt of the activation message. And the small base station recovers the normal transmitting power and recovers the normal state from the energy-saving state.
In addition, when the energy-saving time period (the preset energy-saving time period) is over, the small base station in the energy-saving state can automatically exit the energy-saving state, and the normal transmission power is recovered.
However, the existing small base station shutdown technology has a problem that if the macro base station of the compensation cell fails in the sleeping process of the small base station, the small base station cannot timely discover the failure of the macro base station and timely start the macro base station because the small base station does not receive the instruction of starting the macro base station, and therefore a certain coverage hole is caused, and even the small base station cannot be started at a service peak, so that the service quality is affected.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
The invention provides various solutions for solving the problem that a macro base station with a fault cannot be found in time and a corresponding small base station cannot be awakened in the prior art, and the method specifically comprises the following steps:
example one
As shown in fig. 5, an embodiment of the present invention provides a method for identifying and processing a base station failure, which is applicable to a small base station serving as an energy saving cell, and includes:
step 51: monitoring heartbeat packets periodically sent by a macro base station serving as a compensation cell during the period that the small base station is in the energy-saving state;
step 52: and if the heartbeat packet is not received within a preset time period, judging that the macro base station has a fault, and controlling the small base station to exit the energy-saving state.
In the base station fault identification processing method provided by the embodiment of the invention, when the small base station is in the energy-saving state, the heartbeat packet periodically sent by the corresponding macro base station serving as the compensation cell is monitored, and when the heartbeat packet is not received within a preset time period, the macro base station is judged to have a fault, and the small base station is controlled to exit the energy-saving state; the macro base station serving as a compensation cell and having a fault can be found in time, the corresponding energy-saving cell is awakened, and the coverage hole of the network is reduced.
Further, before the small cell enters the energy saving state, the base station fault identification processing method further includes: judging whether the load of the small base station is smaller than or equal to a first small base station turn-off threshold value or not, and the load of the macro base station is smaller than or equal to a second small base station turn-off threshold value; if yes, sending a base station configuration updating message to the macro base station;
receiving a first heartbeat packet fed back by the macro base station according to the base station configuration updating message, and starting timing; the first heartbeat packet is a first heartbeat packet sent by the macro base station aiming at the small base station entering the energy-saving state at this time.
Considering that the heartbeat packet may be included in the base station configuration update response message or may be a separate signaling, the present embodiment provides two strategies:
first, in response to a condition that a heartbeat packet is a separate signaling, in this embodiment, after sending a base station configuration update message to the macro base station, the method for identifying and processing a base station failure further includes: receiving a base station configuration update response message fed back by the macro base station according to the base station configuration update message, and controlling the small base station to enter an energy-saving state; wherein the base station configuration update response message is received at the same time as or before the first heartbeat packet is received.
That is, after sending the base station configuration update message to the macro base station, and at the same time or before receiving the first heartbeat packet fed back by the macro base station according to the base station configuration update message, receiving the base station configuration update response message.
Second, in response to a condition that a heartbeat packet is included in a base station configuration update response message, in this embodiment, the step of receiving the heartbeat packet fed back by the macro base station according to the base station configuration update message and starting timing includes: receiving a base station configuration updating response message fed back by the macro base station according to the base station configuration updating message; acquiring a cell dormancy indication from the base station configuration update response message; controlling the small base station to enter an energy-saving state according to the cell dormancy indication; and acquiring a first heartbeat packet sent by the macro base station from the base station configuration updating response message, and starting timing.
Wherein controlling the small cell to enter the energy saving state is preferably performed before starting timing.
When the heartbeat packet is continuously transmitted in the subsequent procedure, the heartbeat packet may be preferably transmitted in a separate signaling manner, and may of course be continuously included in the base station configuration update response message, which is not limited herein.
In order to facilitate continuous operation and ensure processing accuracy, in this embodiment, before the small cell enters the energy saving state, the base station fault identification processing method further includes: directly communicating with the macro base station to agree on a sending period of the heartbeat packet; or appointing the sending period of the heartbeat packet with the macro base station through a network manager; the preset time period is N times of the sending period, and N is a positive integer.
In this embodiment, before monitoring that the heartbeat packet is not received within a preset time period, the method for identifying and processing a failure of a macro base station further includes: receiving a cell activation request message sent by the macro base station; and controlling the small base station to exit the energy-saving state according to the cell activation request message, and feeding back a cell activation response message to the macro base station.
Further, when the heartbeat packet periodically sent by the macro base station serving as the compensation cell corresponding to the monitoring is monitored, the base station fault identification processing method further includes: and if the heartbeat packet is received within a preset time period, judging that the macro base station normally operates without failure.
And directly continuing to monitor subsequently.
As can be seen from the above, the base station failure identification processing method provided in this embodiment well solves the problem that a macro base station having a failure cannot be found in time in the prior art, and a corresponding small base station is awakened.
Example two
As shown in fig. 6, a second embodiment of the present invention provides a method for identifying and processing a base station failure, which is applicable to a macro base station serving as a compensation cell, and includes:
step 61: detecting whether a base station configuration updating message sent by a corresponding small base station serving as an energy-saving cell is received, wherein the base station configuration updating message is a message for requesting the small base station to enter an energy-saving state;
step 62: and if the base station configuration updating message is received, starting to periodically feed back the heartbeat packet of the macro base station to the small base station.
In the method for identifying and processing a base station fault provided by the second embodiment of the present invention, after receiving a base station configuration update message sent by a small base station, the small base station knows that the small base station is about to enter an energy saving state, and then starts to periodically feed back a heartbeat packet of a macro base station to the small base station; the small base station can know the state of the macro base station through the heartbeat packet, and can timely find the state when the macro base station fails, so that the small base station exits the energy-saving state, and the coverage hole of the network is reduced.
Considering that the heartbeat packet may be included in the base station configuration update response message or may be a separate signaling, the present embodiment provides two strategies:
first, in response to a condition that a heartbeat packet is an independent signaling, in this embodiment, if the base station configuration update message is received, the method for identifying and processing a base station failure further includes: feeding back a base station configuration update response message to the small cell, wherein the base station configuration update response message is used for indicating the small cell to enter an energy-saving state; and feeding back the base station configuration update response message to the small cell at the same time or before the heartbeat packet is fed back to the small cell periodically.
Second, in response to a heartbeat packet being included in the base station configuration update response message, in this embodiment, the step of starting to periodically feed back the heartbeat packet of the macro base station to the small base station includes: placing the first heartbeat packet of the macro base station, which enters the energy-saving state for the small base station at this time, in the base station configuration updating response message, and feeding back the first heartbeat packet to the small base station; the base station configuration update response message includes a cell dormancy indication indicating that the small base station enters an energy-saving state and the first heartbeat packet.
When the heartbeat packet is continuously transmitted in the subsequent procedure, the heartbeat packet may be preferably transmitted in a separate signaling manner, and may of course be continuously included in the base station configuration update response message, which is not limited herein.
In order to facilitate continuous operation and ensure processing accuracy, in this embodiment, before the detecting whether a base station configuration update message sent by a corresponding small base station serving as an energy-saving cell is received, the base station failure identification processing method further includes: directly communicating with the small base station to appoint the sending period of the heartbeat packet; or appointing the sending period of the heartbeat packet with the small base station through a network manager.
In this embodiment, after the starting of periodically feeding back the heartbeat packet of the macro base station to the small base station, the method for identifying and processing a failure of a base station further includes: judging whether the load of the macro base station is greater than or equal to a cell awakening threshold value or not; if yes, sending a cell activation request message to the small base station; receiving a cell activation response message fed back by the cell base station according to the cell activation request message; and stopping feeding back the heartbeat packet to the small base station according to the cell activation response message.
This can save resources.
As can be seen from the above, the base station failure identification processing method provided in this embodiment well solves the problem that a macro base station having a failure cannot be found in time in the prior art, and a corresponding small base station is awakened.
The base station fault identification processing method provided by the embodiment of the invention is further described below by combining the two sides of the small base station and the macro base station.
In view of the above technical problems, embodiments of the present invention provide a base station fault identification processing method capable of timely discovering a macro base station serving as a compensation cell that has a fault, waking up a corresponding energy-saving cell (cell base station), and reducing a coverage hole of a network, and may also be understood as providing a method for periodically sending heartbeat packets between the macro base station and the cell base station to maintain state communication, that is, when the energy-saving cell is dormant, the macro base station periodically sends heartbeat packets to the energy-saving cell base station, so that the energy-saving cell can know the state of the macro base station in real time, and make a judgment and a decision; the scheme is mainly divided into the following two stages:
first, preparation phase
The sending period of the heartbeat packet needs to be agreed between the macro base station and the small base station, and two agreed modes are provided:
firstly, for the used equipment in the current network, according to the configuration of a compensation cell of a macro base station and an energy-saving cell of a small base station, before the energy-saving cell is closed, the configuration is sent to the macro base station and the small base station by a network management system in advance;
second, for the next generation device, a certain period may be agreed in the standard, or the network management may be adopted, either way.
Second, execution stage
The small base station prepares for dormancy, and sends a base station Configuration Update message eNB Configuration Update to the macro base station.
The macro base station sends a base station Configuration Update response message eNB Configuration Update Ack to the small base station, and sends a heartbeat packet to the small base station, where the heartbeat packet may be included in the eNB Configuration Update Ack or may be a separate signaling.
The small base station receives the heartbeat packet according to an appointed period and judges according to the appointed time. The specified time is defined as N times (N is a positive integer) of the specified period, and if the time interval for receiving the heartbeat packet is less than the specified time, the macro base station is considered to be normally operated without failure; and if the heartbeat packet is not received within the specified time, the macro base station is considered to have a fault, and the small base station is automatically started.
When the load of the macro base station exceeds a preset wake-up threshold (Cell wake-up threshold) of the small base station shutdown technology, the macro base station sends a Cell Activation Request message to the small base station to wake up the small base station in an energy-saving state, the small base station returns to a normal state (exits the energy-saving state), and feeds back a Cell Activation Response message CellActivation Response to the macro base station. And the macro base station stops sending the heartbeat packet after receiving the Cell Activation Response message.
