It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

In order to solve the problem of the prior art, embodiments of the present invention provide a method, an apparatus, a device, and a medium for managing status data of a radio remote unit. First, a method for managing status data of a remote radio unit according to an embodiment of the present invention is described below.

Fig. 1 is a flowchart illustrating a method for managing status data of a remote radio unit according to an embodiment of the present invention. As shown in fig. 1, the method includes:

s101, when a radio remote unit RRU accesses to a network, establishing a time chain of the RRU according to the access time point of the RRU, wherein the starting time point of the time chain is the access time point of the RRU.

And S102, recording the state of the RRU as a working state on a time chain.

S103, when the RRU exits the network, setting the ending time point of the time chain as the network exiting time point of the RRU, and modifying the state of the RRU on the time chain into a non-working state.

The state data management method of the RRU of the embodiment of the invention records the state of the RRU on the time chain of the RRU when the RRU is connected to the network and modifies the state of the RRU when the RRU is disconnected from the network, thereby realizing the state storage of the RRU which changes. In the prior art, snapshot storage is periodically performed on the RRU state, that is, all the acquired RRU states are stored after the RRU is networked. The embodiment of the invention is different from the prior art, and not all the acquired RRU states are stored, thereby reducing the storage space and the computing resource occupied by the RRU state data on the premise of ensuring that the RRU state data is not lost. As the RRU state data is less, the retrieval and updating efficiency of the RRU state data is improved, and the response speed of the system is ensured.

After the embodiment of the invention is adopted, the storage space is saved by more than 5 times compared with the existing storage mode. For example, a certain province has 50 thousands of RRUs, and the states of the 50 thousands of RRUs are collected every 4 hours, and a 4T space is needed to store the states of all the collected 50 thousands of RRUs in a year. After the existing storage mode is adopted, only about 500G of storage space is needed to store the states of the 50 ten thousand RRUs. The RRU state data stored in the embodiment of the invention is less, so that the retrieval efficiency can be improved by more than 2 times.

In an embodiment of the present invention, after the RRU is networked, the method for managing status data of the remote radio unit further includes:

if the RRU performs network cutover, setting the ending time point of the time chain as the time point of the RRU performing network cutover, and creating another time chain of the RRU, wherein the starting time point of the another time chain is the time point of the RRU performing network cutover; and recording the state of the RRU as a working state on the other time chain.

In the state data management method for the remote radio unit according to the embodiment of the present invention, if the RRU performs the network cutover, the two RRUs physically belong to the same RRU but have two roles in the network with respect to the RRU before the network cutover and the RRU after the network cutover. Therefore, another time chain is established for the RRU which is cut by the network, and the state of the RRU with the changed role in the network is recorded on the time chain, so that the state of the RRU is effectively managed.

In an embodiment of the present invention, the method for managing status data of a remote radio unit further includes:

when the RRU exits the network, setting the ending time point of another time chain as the network exiting time point of the RRU, and modifying the state of the RRU on the other time chain into a non-working state.

periodically collecting state data of the RRU; if the state data of the RRU is not acquired in the previous period and the state data of the RRU is acquired in the current period, determining that the RRU is accessed to the network; and if the state data of the RRU is acquired in the previous period and the state data of the RRU is not acquired in the current period, determining that the RRU exits the network.

and recording the information of the cell served by the RRU network access station on the time chain.

For example, the name or cell identifier of the cell served by the RRU network access point is recorded on the time chain.

It should be noted that the time chain records the network access time of the RRU, the working state of the RRU, and the information of the cell served by the RRU accessing the network, and when the RRU leaves the network, the time chain also records the network leaving time of the RRU.

In one embodiment of the invention, the ending time point of the time chain is empty when the time chain is created.

It should be added that, if the RRU performs network cutover, and creates another time chain for the RRU, the ending time point of the another time chain is also empty.

In one embodiment of the invention, the time chain is stored in an Operation and Maintenance Center (OMC) that is used to manage the RRUs.

The embodiment of the invention provides another state data management method for a radio remote unit, which comprises the following steps:

(1) establishing a network access time point (StartTime) and a network exit time point (EndTime) in a table structure of a database RRU, wherein a time range between the network access time point and the network exit time point represents an effective time range of the RRU. And warehousing each RRU time chain to be managed by the OMC during initial acquisition, wherein the starting time point of each RRU time chain is the network access time point of the RRU, and the ending time point of the RRU time chain is empty (such as NULL), namely starting the time chain.

(2) If the state of the RRU is acquired in the last acquisition period and the state of the RRU is not acquired in the acquisition period, determining that the RRU exits the network, ending the RRU time chain, namely directly setting the ending time point of the RRU time chain as the network exiting time point of the RRU, wherein the network exiting time point refers to the time point for determining that the RRU exits the network.

(3) If the state of the RRU is not acquired in the previous acquisition period and the state of the RRU is acquired in the current acquisition period, determining that a new RRU is accessed to the network, newly adding an RRU time chain, namely directly adding an RRU record, and setting the starting time point of the newly added RRU time chain as the access time point of the RRU, wherein the access time point refers to the time point of determining the new RRU to be accessed to the network. The end time point of the newly added RRU time chain is NULL.

(4) If the field of a certain RRU changes, which indicates that the RRU performs network cutover, the time chain of the RRU is split, namely, the ending time point of the RRU time chain before the network cutover is set as the time point when the field of the RRU which is currently acquired changes, then an RRU time chain is newly added, the newly added RRU time chain records RRU data after the network cutover, the starting time point of the newly added RRU time chain is the time point when the field of the RRU which is acquired changes, and the ending time point of the newly added RRU time chain is NULL.

The following describes the examples of the present invention in Table 1.
