Description

Neighbor relationship management method and equipment

The present invention relates to communication technologies, and in particular, to a neighbor relationship management method and device.

Background technique

In the mobile communication system, the base station is the most basic device for realizing mobile communication, and transmits information between the mobile communication switching center and the mobile telephone terminal through a mobile communication switching center in a certain radio coverage area. The base station is usually deployed by the operator through network planning, and the running status is managed by the operator.

With the development of mobile communication technology, user requirements are becoming more and more diverse, and system equipment is also diversified in order to meet this demand. The home indoor coverage and enterprise-level internal coverage base stations, and some other restricted networks that have attracted much attention. It came into being. Such networks may be home cells, access points (APs), private networks, private cells, etc., as well as restricted networks of certain frequency layers.

For the private network scenario, the concept of a Closed Subscriber Group (CSG) has been introduced. If a user subscribes to a CSG user group or is added to a CSG user group by the CSG owner in the CSG network, the user is added. It is allowed to normally reside in the CSG cell and apply for services. From a network perspective, a CSG may contain one cell or multiple cells; users who have not signed up and are not added to the CSG by the CSG owner cannot camp in the CSG cell and cannot initiate normal services.

The main application of the CSG is a home base station (Home NodeB or Home eNB, which is referred to as H(e)NB). The H(e)NB is a small base station device purchased and installed by the user, usually via an IP network. Connect to the carrier's core network. Users can turn H(e)NB on or off as needed. In application, the H(e)NB needs to register first or establish a connection to the home base station gateway (H(e)NB Gateway/, H(e)NB GW), and then through the H(e)NB GW and the core network entity. Signaling and user data interaction. When H(e)NB registers or establishes a connection to the H(e)NB GW, it reports some of its own configuration information, and H(e)NB is mainly applied to the restricted network.

In order to distinguish the base station deployed by the operator through the network planning, the base station deployed in the existing wireless network is referred to as a macro base station (NodeB or eNB), and a large number of home base stations can be deployed under one macro base station. In order to ensure call quality and network performance, it is necessary to effectively manage the neighbor relationship of the macro base station. The neighbor relationship of the macro base station is configured by the operator during network planning. For the Long Term Evolution (LTE) network, the user equipment (UE) can also be used to assist in discovering the new neighboring area. The Self-Organized Network, SO) server updates the neighbor relationship.

If the H(e)NB is not deployed in the network planning, if the neighbor relationship between the macro base station and the H(e)NB is planned through the carrier network, the operator needs to monitor the running status of the H(e)NB. Update the neighbor relationship of the neighboring H(e)NBs in the macro cell, which will place a heavy burden on the network planning and configuration of the operator.

detailed description

The embodiments of the present invention are further described in detail below with reference to the accompanying drawings and embodiments.

Referring to FIG. 1 , it is a flowchart of a first embodiment of a neighbor relationship management method according to the present invention, which includes the following steps:

Step 101: Receive new configuration information reported by the H(e)NB.

The new configuration information reported by the H(e)NB includes: a Primary Synchronisation Code (PSC)/Physical Cell Identity (PCI), a Closed Subscriber Group Identifier (CSG ID), (E) CGL access mode, carrier frequency, and frame offset. In addition, it may further include: location information of H(e)NB and/or H(e)NB Detected neighboring macro cells.

Step 102: Update the H(e)NB neighbor macro macro set according to the new configuration information of the H(e)NB. According to the new configuration information reported by the H(e)NB, the manner of updating the H(e)NB neighboring macro cell set according to the new configuration information of the H(e)NB in step 102 is also different. This is described in detail separately.

(1) The new configuration information reported by the H(e)NB includes the location information of the H(e)NB, and then updating the H(e)NB neighboring macro cell set includes:

If the H(e)NB is the initial registration, the macro base station that meets the predetermined requirement between the H(e)NB and the H(e)NB is listed in the H(e)NB adjacent according to the location information of the H(e)NB Within the macro cell set. The location information of the H(e)NB and the macro base station can be obtained by the following methods: Location Service (LCS), Global Positioning System (GPS), or port number information. If the distance between the found macro base station and the H(e)NB is less than the set distance, the macro base station is included in the H(e)NB neighbor macro cell set.

If the H(e)NB is not the initial registration, determining whether the H(e)NB neighbor macro macro set has changed according to whether the location information of the H(e)NB changes, and updating the H (e) NB neighbor macro cell set.

(2) If the new configuration information reported by the H(e)NB includes the neighboring macro cell detected by the H(e)NB, updating the H(e)NB neighboring macro cell set includes:

If the H(e)NB is the initial registration, the neighboring macro cell detected by the H(e)NB is included in the H(e)NB neighbor macro cell set.

If the H(e)NB is not the initial registration, the neighboring macro cell detected by the H(e)NB determines whether the H(e)NB neighbor macro macro set has changed, and updates the H (e) NB neighbor macro cell set.

In this case, the network side needs to store the neighbor macro cell set information of the H(e)NB.

Step 103: Update a neighbor list and a mapping relationship of the macro base station in the H(e)NB neighboring macro cell set according to the new configuration information of the H(e)NB.

For an LTE or E-UTRAN system, the HeNB neighbor list of the macro base station includes: PCI, carrier frequency, and mapping relationship. The mapping relationship refers to a correspondence between a PCI + GSG ID + CGI + access mode + carrier frequency + frame offset of the HeNB in the neighbor list. Step 104: Send the updated neighbor list and mapping relationship to the corresponding macro base station in the H(e)NB neighbor macro cell set.

In the embodiment of the present invention, the method further includes the following steps:

Receiving a shutdown notification of the H(e)NB when the H(e)NB is powered off, and, after receiving the notification, notifying the macro base station in the neighboring macro cell set of the H(e)NB that the home base station is in a non- An activation state; receiving a power-on notification of the H(e)NB when the H(e)NB is powered on, and notifying the macro base station in the neighboring macro-cell set of the H(e)NB after receiving the notification The base station is active.

It can be seen that, in the neighboring area relationship management method of the embodiment of the present invention, the network side updates the H(e)NB neighboring macro cell set and the H(e)NB neighboring macro cell set according to the new configuration information reported by the H(e)NB. A neighboring cell list and a mapping relationship of the macro base station, and sending the updated neighboring cell list and mapping relationship to the corresponding macro base station in the H(e)NB neighboring macro cell set. Therefore, the corresponding macro base station in the H(e)NB neighboring macro cell set can update the locally saved neighbor list and the mapping relationship according to the updated neighbor list and mapping relationship. The burden of the operator network planning when the operator plans to configure the neighbor cell list and mapping relationship of the macro cell is solved, and the neighbor list and mapping relationship of the H(e)NB in the macro cell are automatically configured by the network.

In the prior art, if the neighboring cell relationship of the neighboring H(e)NBs in the macro cell is managed by the automatic neighbor relationship of the SON server, when the macro cell finds that the PSC or PCI reported by the UE is not in its neighboring cell, The UE is required to report the (E-) UTRAN Cell Global Identifier (E) CGI of the cell that does not exist in the neighboring cell to determine whether to configure the neighbor relationship. This requires the UE to read a large amount of H(e)NB broadcast information and waste air interface resources. In addition, since the H(e)NB is deployed densely, the H(e)NBs within the coverage of the same macro cell are allowed to have the same PSC or PCI, and thus the neighbor relationship may be incomplete; The UE may measure the quality of the same cell, and the H(e)NB is generally a CSG cell, and only some users are allowed to access. When different UEs are denied access by the same PSC or PCI cell, SON The server deletes the cell as a pseudo-neighbor from the neighbor relationship of the macro cell, so that some users of the CSG cell cannot access normally.

In the method of the embodiment of the present invention, since the neighbor list and the mapping relationship of the H(e)NB in the macro cell are automatically configured by the network, the PSC or PCI conflict occurs in the H(e)NB neighbor list by using the SON server. The problem that the neighbor cell list cannot be completely configured causes the CSG cell to be deleted as a pseudo cell from the neighbor list. The neighbor relationship management method in the embodiment of the present invention does not require the UE to read a large number of H(e)NBs. Broadcast information saves air interface resources.

Referring to FIG. 2, it is a flowchart of a second embodiment of a neighbor relationship management method according to the present invention, which includes the following steps:

Step 201: After the initial registration or the configuration information changes, the H(e)NB detects whether the neighboring macro cell changes.

Step 202: If the neighboring macro cell changes, update the H(e)NB neighboring macro cell set, and notify the H(e)NB neighboring macro cell set to change the macro base station to update the neighbor relationship. .

Specifically, the macro base station that has changed can have the following two situations:

(1) The changed macro base station is within the updated H(e)NB neighbor macro cell set.

In this case, the H(e)NB needs to send the updated neighbor relationship signaling to the macro base station, where the signaling includes configuration information of the H(e)NB, specifically, the following information: PSC/PCI, CSG ID, CGI, access mode, carrier frequency, and frame offset.

(2) The changed macro base station is not in the updated H(e)NB neighboring macro cell set, that is, the macro base station changes in the H(e)NB neighboring macro cell set before the update. The macro base station is no longer in the neighboring macro cell of the H(e)NB.

In this case, the H(e)NB is required to save its neighbor macro cell set information.

In this case, the H(e)NB needs to send the deleted H(e)NB signaling to the macro base station, and informs it to delete the related information of the H(e)NB in the neighbor list.

In this way, the macro base station can update the locally saved neighbor list and mapping relationship according to the notification of the H(e)NB.

In the above method of the embodiment of the present invention, the method further includes the following steps:

And when the H(e)NB is powered off, notifying the macro base station in the neighboring macro cell set that the H(e)NB is in an inactive state;

When the H(e)NB is powered on, it notifies the macro base station in the neighboring macro cell set that the H(e)NB is in an active state.

It can be seen that, in the neighboring area relationship management method of the embodiment of the present invention, the neighboring macro cell is automatically detected by the H(e)NB, and after detecting the change of the neighboring macro cell set, the neighboring macro cell set is updated, and the neighboring macro cell set is updated. The macro base station that changes in the H(e)NB neighboring macro cell set updates the neighbor relationship, so that the corresponding macro base station can update the locally saved neighbor list and the mapping relationship according to the notification of the H(e)NB. solved When the operator plans to configure the neighboring cell list of the macro cell, the carrier network planning burden is implemented, and the neighboring cell list and mapping relationship of the H(e)NB in the macro cell are automatically configured, thereby avoiding the use of the SON server to configure the neighboring cell list to appear PSC. Or the PCI conflict cannot completely configure the neighbor list, which causes the CSG cell to be deleted as a pseudo cell from the neighbor list. In the neighboring cell relationship management method of the embodiment of the present invention, the UE does not need to read a large amount of H(e)NB broadcast information, thereby saving air interface resources.

Referring to FIG. 3, it is a flowchart of a third embodiment of a neighbor relationship management method according to the present invention, which includes the following steps:

Step 301: The macro base station receives the signaling sent by the H(e)NB or the neighbor list and the mapping relationship sent by the network side.

Specifically, according to the change of the neighboring macro cell detected by the H(e)NB, the signaling sent by the H(e)NB may be multiple, for example, the neighbor cell relationship signaling may be updated, where the signaling is The configuration information including the H(e)NB includes, in particular, the following information: PSC/PCI, CSG ID, CGI, access mode, carrier frequency, and frame offset. The signaling sent by the H(e)NB may also be to delete the H(e)NB signaling, and notify the UE to delete the related information of the H(e)NB in the neighbor list. For details, refer to the description in the embodiment of the present invention shown in FIG. 2 above.

Of course, in addition to the neighbor list and mapping relationship of the macro base station, the network side may also delete related information of the H(e)NB.

Step 302: Update the locally saved neighbor list and the mapping relationship according to the signaling or according to the neighbor list and the mapping relationship.

Corresponding to the signaling sent by the H(e)NB in step 301, if the signaling sent by the H(e)NB is: updating the neighbor relationship signaling, the macro base station may be included according to the signaling The configuration information of the H(e)NB updates the locally saved neighbor list and mapping relationship. If the signaling sent by the H(e)NB is: deleting H(e)NB signaling, the macro base station deletes related information of the H(e)NB in the locally saved neighbor list.

In order to enable the macro base station to better maintain the locally saved neighbor list, in the embodiment of the present invention, state setting may be further performed for each H(e)NB in the neighbor list. Specifically, after receiving the H(e)NB shutdown notification, the macro base station sets the H(e)NB in the locally saved neighbor list to an inactive state; after receiving the H(e)NB boot notification, The H(e)NB in the locally saved neighbor list is set to an active state. Specifically, the macro base station can receive the directly from the H(e)NB The shutdown notification or the power-on notification may also be that the shutdown notification or the power-on notification is received through the network side. In this way, in the embodiment of the present invention, the macro base station may further maintain the neighbor list according to the status of each H(e)NB in the locally saved neighbor list. The specific implementation may be implemented in multiple manners, for example: (1) when the H(e)NB is in an inactive state, the macro base station starts a corresponding timer; after the timer expires, if the H(e)NB If it is still in an inactive state, the H(e)NB is deleted from the neighbor list stored locally by the macro base station.

(2) The macro base station periodically detects the H(e)NB in the locally saved neighbor list; if the H(e)NB is not detected within the predetermined number of times, the H(e)NB is The neighboring cell list saved locally by the macro base station is deleted.

In this way, the invalid H(e)NB and mapping relationship in the neighbor list can be deleted in time to avoid affecting the system broadcast information configuration and measurement control configuration of the macro cell.

It can be seen that, in the neighbor relationship management method of the embodiment of the present invention, the macro base station directly updates the locally saved neighbor list and mapping relationship according to the signaling sent by the H(e)NB, and does not need to plan and configure the H(e)NB in the macro cell by the operator. Neighbor list and mapping relationship, which reduces the burden of network planning, avoids the use of SON server to configure the neighbor list, PSC or PCI conflicts, unable to completely configure the neighbor list, and the CSG cell is deleted as a pseudo cell from the neighbor list. The problem. In the neighboring cell relationship management method of the embodiment of the present invention, the UE does not need to read a large amount of H(e)NB broadcast information, thereby saving air interface resources. The state maintains the list of neighbors. Therefore, system broadcast information and measurement control information can be configured accurately and accurately, and the UE can be prevented from frequently searching for invalid neighbor cells.

A person skilled in the art can understand that all or part of the steps of implementing the above embodiments can be completed by a program to instruct related hardware, and the program can be stored in a computer readable storage medium, the storage. Media, such as: ROM/RAM, disk, CD, etc.
