Description
Technical Field
The present invention relates to the field of wireless communications, and in particular, to a method and an apparatus for location management.
Background
With the wide application of mobile access networks, the requirements of operators on high wireless access rate and low construction cost are more strict, for the operators, on one hand, deployment of Home evolved Node bs (henbs) can provide better wireless network coverage in an indoor environment, on the other hand, loads of outdoor base stations can be reduced, and meanwhile, better service quality can be provided for outdoor users.
There are two solutions to managing the location of a HeNB in the prior art.
The first scheme is as follows: the position management is performed through a Global Positioning System (GPS) module of the HeNB, the information of the longitude and latitude, the altitude and the like of the HeNB is reported to the network management System through the GPS, the network management System can compare the obtained new position information with the position information recorded last time, and whether the current position of the HeNB is changed or not is judged according to the comparison result.
Although the position of the HeNB can be managed by adopting the first scheme, because the cost of the GPS module is too high, most HeNBs which operate at present are not provided with the GPS module, and the HeNBs of the parts provided with the GPS module are basically arranged indoors, and the strength of GPS signals in the indoor space is very weak, therefore, even if the GPS module is arranged, the position information can not be accurately obtained for the HeNBs arranged indoors.
Scheme II: the location information is manually configured for each HeNB in advance, for example, the location information of the HeNB1 may be configured to be "XX street XX number XX in XX district XX in XX city", and a maintenance person may determine whether the current location of the HeNB1 changes according to the configuration information.
Although the position of the HeNB can be managed by adopting the second scheme, when the position of the HeNB changes, the position information configured by the HeNB is not updated in time, for example, if the position of the HeNB1 moves from the street 34 a to the street 58B and the position information is not updated in time, the position information of the HeNB1 obtained by the maintenance personnel at this time is still the street 34 a in the XX district in the XX city, and whether the position of the HeNB1 has changed or not cannot be judged.
In view of the above, a new location management method is needed to overcome the above-mentioned drawbacks.

Detailed Description
In order to solve the problem that the position of the HeNB cannot be efficiently managed in the prior art, in the embodiment of the present invention, a position management method is designed, and the method includes: and judging the position change of the target HeNB according to the change of the neighbor cells around the target HeNB.
The present invention will be described in detail with reference to specific examples, but it is to be understood that the present invention is not limited to the examples.
In the embodiment of the present invention, a location management procedure is described by taking an HeNB of a 4G network as an example, in a network architecture in which the HeNB is a main serving cell, a neighbor cell of the HeNB may be a cell under the HeNB, or a cell under an evolved Node B (eNB), as shown in fig. 1, and in actual application, one main serving cell may be configured with 32 neighbor cells for the HeNB, where the neighbor cell is a cell that has network coverage overlapping with the main serving cell and has a handover relationship.
In the embodiment of the present invention, a Location information analysis module (LAM) of a network management system is used, hereinafter referred to as an LAM device, to obtain a current neighbor cell set of a target HeNB, and then compare identification information of each neighbor cell in the current neighbor cell set with identification information of each neighbor cell in a last recorded neighbor cell set, and determine whether a current Location of the HeNB moves according to a comparison result, where one network management system at least includes a configuration device, an LAM device, and an alarm device, and there are communication interfaces between the LAM device and the configuration device as well as between the LAM device and the alarm device, as shown in fig. 2.
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 3, a specific procedure for managing the location of the HeNB in the embodiment of the present invention is as follows:
step 300: and the LAM device acquires the current neighbor cell set of the target HeNB.
Specifically, before acquiring a current neighbor Cell set of a target HeNB, an LAM device acquires the current neighbor Cell set of the target HeNB through a configuration device, where one neighbor Cell in the neighbor Cell set includes identification information such as a Cell identity (Cell ID), a Physical Cell Identity (PCI), a Public Land Mobile Network (PLMN) identity, and the like.
The method for configuring the device to acquire the current neighbor cell set of the target HeNB may be divided into the following two methods:
the first method is as follows: the target HeNB actively reports the current neighbor cell set acquisition to a configuration device of a network management system, wherein the situation of the active reporting of the target HeNB can be divided into the following two situations without limitation: the first condition is as follows: when the target HeNB restarts the operation, the target HeNB will actively report its current neighbor cell set to the configuration device of the network management system. Case two: when at least one neighbor cell in the neighbor cell set acquired by the target HeNB changes, the target HeNB also reports the current neighbor cell set to the configuration device of the network management system actively.
The second method comprises the following steps: and actively inquiring and acquiring the current neighbor cell set of the target HeNB through a network management system.
Further, before acquiring the current neighbor cell set of the target HeNB, the configuration apparatus needs the target HeNB to acquire the current neighbor cell set of the target HeNB first, and the target HeNB may acquire the current neighbor cell set of the target HeNB through configuration information or an automatic scanning manner.
Further, after acquiring the current neighbor cell set of the target HeNB, the configuration device sends the neighbor cell set to the LAM device.
Specifically, after acquiring the current neighbor Cell set of the target HeNB, the configuration device may send the current neighbor Cell set of the target HeNB to the LAM device through a neighbor Cell notification message, where the neighbor Cell notification message may include a Cell ID of the target HeNB, the number of neighbor cells, a Cell ID of a neighbor Cell, and the like. After receiving the current neighbor Cell set of the target HeNB, the LAM device feeds back a neighbor Cell notification response message to the configuration device, indicating that the configuration device has received the current neighbor Cell set of the target HeNB, where the neighbor Cell notification response message may include a Cell ID of the target HeNB.
Step 310: the LAM device matches the identifier information of each neighbor cell in the current neighbor cell set with the identifier information of each neighbor cell in the neighbor cell set acquired last time for the target HeNB.
Specifically, the LAM device reads the identification information of each neighbor cell in the current neighbor cell set of the target HeNB through the configuration device, stores the identification information of each neighbor cell in the corresponding location table after reading the identification information of each neighbor cell, and matches the identification information of each neighbor cell in the neighbor cell set obtained for the target HeNB last time with the identification information of each neighbor cell in the neighbor cell set.
For example, referring to fig. 4, the identification information of each neighboring Cell in the current neighboring Cell set of the target HeNB read by the LAM device is shown in the current location table, the identification information of each neighboring Cell in the neighboring Cell set obtained by the target HeNB last time is shown in the last location table, and if n is 3, the neighboring Cell 1_ Cell ID in the current location table is matched with the neighboring Cell 1_ Cell ID ' in the last location table, the neighboring Cell 2_ Cell ID in the current location table is matched with the neighboring Cell 2_ Cell ID ' in the last location table, and the neighboring Cell 3_ Cell ID in the current location table is matched with the neighboring Cell 3_ Cell ID ' in the last location table one by one, that is, whether the values of two corresponding Cell IDs in the current location table and the last location table are the same is determined.
Further, if the current neighbor cell set of the target HeNB obtained by the LAM device is the neighbor cell set in the initial starting state of the target HeNB, and before that, the current location table and the last location table in the LAM device are empty tables, therefore, the LAM device stores the identification information of each neighbor cell extracted from the neighbor cell set into the corresponding location of the current location table and the last location table, and if the LAM device obtains the current neighbor cell set of the target HeNB again, the current location table in the LAM device is updated to the latest obtained current neighbor cell set of the target HeNB, and the last location table is maintained unchanged.
Step 320: and the LAM device determines that the matching is unsuccessful according to the obtained matching result.
Specifically, the LAM device matches the current neighbor cell set with the neighbor cell set acquired last time for the target HeNB to obtain the correlation matching result, and determines that the matching is unsuccessful when it is determined that at least one piece of identical neighbor cell identification information does not exist in the current neighbor cell set and the neighbor cell set acquired last time according to the correlation matching result.
For example, still taking the example in step 310 for explanation, assuming that n is 3, assuming that the neighboring Cell 1_ Cell ID is "0123", the neighboring Cell 2_ Cell ID is "0124", and the neighboring Cell 3_ Cell ID is "0125" in the existing location table, assuming that the neighboring Cell 1_ Cell ID ' is "0126", the neighboring Cell 2_ Cell ID ' is "0127", and the neighboring Cell 3_ Cell ID ' is "0128" in the last location table, it may be determined that the matching is unsuccessful.
Further, if the matching result obtained by the LAM device indicates that at least one piece of same neighbor cell identification information exists in the current neighbor cell set and the neighbor cell set obtained for the last time, it is determined that the matching is successful.
For example, still taking the example in step 310 for explanation, assuming that n is 3, assuming that in the existing location table, the neighboring Cell 1_ Cell ID is "0123", the neighboring Cell 2_ Cell ID is "0124", and the neighboring Cell 3_ Cell ID is "0125", assuming that in the last location table, the neighboring Cell 1_ Cell ID ' is "0123", the neighboring Cell 2_ Cell ID ' is "0127", and the neighboring Cell 3_ Cell ID ' is "0128", from the above, the values of the current Cell ID of the neighboring Cell 1 and the Cell ID of the last neighboring Cell 1 are the same, it may be determined that the matching is successful.
Step 330: and the LAM device confirms that the position of the target HeNB moves and sends alarm information to the alarm device.
Specifically, when the LAM device determines that the matching is unsuccessful according to the matching result, it determines that the position of the target HeNB moves, and sends an alarm message to the alarm device to prompt maintenance personnel that the position of the target HeNB needs to be determined.
For example, still referring to example 1 in step 320, according to the matching result, if the Cell IDs of the neighboring Cell 1, the neighboring Cell 2, and the neighboring Cell 3 in the current neighboring Cell set of the target HeNB obtained by the LAM device are different from the Cell IDs of the neighboring Cell 1, the neighboring Cell 2, and the neighboring Cell 3 in the neighboring Cell set of the target HeNB obtained last time, it is determined that the position of the target HeNB has moved, and an alarm message is sent to the alarm device to notify a maintenance person to confirm, and if the number of the target HeNB is "001", the alarm message may be "HeNB 001 position moved, please confirm".
Further, if the LAM device receives the delete target HeNB indication message, it deletes the relevant content of the target HeNB stored in the current location table and the last location table.
For example, when detecting that the target HeNB is disconnected from the network management system, the configuration device may send a delete target HeNB indication message to the LAM device, where the delete target HeNB indication message is sent by the configuration device to the LAM device, and the content included in the delete target HeNB indication message may be a Cell ID of the target HeNB to be deleted, indicating that the LAM device is notified to delete the neighbor Cell set of the target HeNB.
When the LAM device receives the target HeNB deletion indication message, a target HeNB deletion indication response message is fed back to the configuration device, where the target HeNB deletion indication response message is sent by the LAM device to the configuration device, and the content included in the target HeNB deletion indication response message may be a Cell ID for confirming the target HeNB deletion, indicating that the target HeNB deletion indication message has been received.
