Description

Community management method and system

The present invention relates to the field of communications, and in particular, to a cell management method and system. Background technique

The physical layer of the LTE (Long Term Evolution) system uses OFDM (Orthogonal Frequency Division Multiplexing) technology, and all available frequency bands can be used in each cell. In an LTE system using OFDM, the cell edge signal is relatively weak. Therefore, the user at the cell edge needs a large transmission power, which causes a large interference to the neighboring cell. In addition, the cell edge user is closer to the neighboring cell. It is also more susceptible to uplink and downlink interference from neighboring users and base stations. If the neighboring cell uses the same frequency band, it will cause large inter-cell interference at the cell edge.

For pilot and control channels, the LTE protocol performs inter-cell interference randomization by using different codewords, so inter-cell interference has little effect on the pilot and control channels. However, for shared channels, it is necessary to reduce inter-cell interference and improve system performance by coordinating time-frequency resources and power control used by inter-cell edge users.

At present, the main strategy for reducing inter-cell interference is ICIC (Inter Cell Interference Coordination). By constraining the time-frequency resources used by users at the cell edge to ensure that adjacent areas of adjacent cells belong to several neighbors. The UE of the cell does not occupy the same PRB (Physical Resource Block) as much as possible.

Step 301: Receive a message including an ICIC identifier value, where the ICIC identifier value is used to indicate whether the ICIC is allowed to be performed. Step 302: Determine whether to perform ICIC according to the ICIC identifier value.

In the embodiment of the present invention, by receiving a message including an ICIC identification value, and determining whether to perform ICIC according to the ICIC identification value, unified management of inter-cell interference coordination is realized.

In the embodiment of the present invention, an ICIC identifier is first added between adjacent cell relationships, and the identifiers may be classified into two types according to different identifier locations: in the 3GPP E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) network. IOC (Information Object Class) in the resource model The first ICIC identifier added in the EUtranRelation, or the second ICIC identifier added in the NRT (Neighbor Relation Table).

After the identification is added, an identifier value is set for the ICIC identifier, and the ICIC identifier has two values for indicating whether to perform ICIC. For example, the two values of the ICIC identifier can be set to TRUE (true) and FALSE (false;), for example, mode one: TRUE indicates that ICIC is allowed to be executed between the cells, and FALSE indicates that ICIC is not allowed to be executed between the cells. Of course, it can be understood that the second mode can also be used: TRUE means that ICIC is not allowed to be executed between the cells, and FALSE means that ICIC can be executed between the cells. In the embodiment of the present invention, the method is used as an example; the NMS sets the ICIC identifier value; the ICIC identifier value is notified to the EMS, and the EMS notifies the evolved base station of the ICIC identifier value, and the evolved base station determines the identifier according to the ICIC identifier. Whether you need to implement ICIC.

In another embodiment of the present invention, the two values of the ICIC identifier may be set to 1 and 0, respectively, and 1 indicates ICI is performed between the cells, 0 means that ICIC is not allowed to be executed between the cells, and vice versa.

In the above-mentioned cell management method and system, the network management system sets the identifier value of the inter-cell interference coordination identifier, and sends the inter-cell interference coordination identifier value to the network element management system; the network element management system receives the network management system to send The ICIC identifier value, the stored ICIC identifier value is modified, and the message containing the ICIC identifier value is sent to the evolved base station, and the evolved base station determines whether to perform the ICIC according to the ICIC identifier value in the message; The meta-side refines the centralized network management to inter-cell interference coordination at the cell level.

For a better understanding of a cell management method provided by the embodiment of the present invention, a network management system and a network element management system according to an embodiment of the present invention are introduced.

The embodiment of the present invention manages a network element by using a network, where the network includes two entities: an NMS and an EMS, where the NMS is used to complete the ITU Telecommunications Network (International Telecommunications Union Telecommunication Management Network) The network management layer (NML) function provides network-oriented operation management functions. The EMS is used to complete the element management layer (EML) function in the ITU TMN, that is, to complete device-oriented operation and maintenance. Features.

The interface between the NMS and the EMS is called the Itf-N interface (Interface-N interface, that is, the northbound interface). In the Itf-N interface, some integrated reference points (IRPs, ie, Integration Reference Point) are defined, such as basic configuration management IRP, batch configuration management IRP, and notification IRP. The operation and maintenance functions for the network are accomplished through the functions provided by these integrated reference points.

A cell management method according to an embodiment of the present invention is described below with reference to the accompanying drawings.

FIG. 4 is a schematic flowchart of a cell management method according to another embodiment of the present invention. The cell management method may include the following content.

Step 401: Add an ICIC identifier.

For example, the NMS adds a first ICIC identifier in the IOC EUtranRelation in the 3GPP E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) network resource model. For example, an attribute field may be added in the IOC EUtranRelation, and the attribute field is used as the attribute field. First ICIC logo;

In another embodiment of the present invention, the first ICIC identifier is used to identify whether to allow ICIC between cells, and the attribute field may be isICICAllowed, and the first ICIC identifier may have two values, for example, TRUE respectively. (true) or FALSE (false); TRUE indicates that ICIC is allowed to be performed between the cells, FALSE indicates that ICIC is not allowed in the adjacent interval, and vice versa. In another embodiment of the present invention, the two values of the first ICIC identifier may be set to 1 and 0 respectively, where 1 indicates that ICIC is allowed to be performed between the cells, and 0 indicates that the small IC is not allowed. Interval execution ICIC, the format of the isICICAllowed attribute field is as shown in Table 1:

Table 1

The support ICIC in Table 1 represents whether isICICAllowed indicates support for ICIC management; readability indicates whether the content of the isICICAllowed attribute field is readable; writability indicates whether the content of the isICICAllowed attribute field can be modified; M in the table represents The isICICAllowed attribute field must have a corresponding byte. This step only needs to be performed once. In the subsequent ICIC identification value setting process, only the added identifiers need to be set.

Step 402: Set an ICIC identifier value.

For example, the NMS sets the first ICIC identification value; the NMS can collect the inter-cell edge information through the EMS, analyze the edge information, and determine whether the ICIC needs to be performed on the small area according to the analysis result. In another embodiment of the present invention, the NMS may also determine whether it is necessary to perform ICIC between cells according to an operation instruction of a network administrator. A method for setting an ICIC value by other NMSs that can be obtained by a person skilled in the art can be included in the scope of the present invention, which is not limited by the embodiment of the present invention.

If the NMS determines that ICIC needs to be performed between cells, the first ICIC identification value is set to TRUE;

The NMS determines that ICIC is not required between cells, and sets the first ICIC flag value to FALSE, and vice versa. In another embodiment of the present invention, if the NMS determines that ICIC needs to be performed between cells, the first ICIC identifier value is set to 1; if the NMS determines that ICIC is not required between cells, the first ICIC identifier value is set to 0. , step 403, notifying the EMS of the identifier value;

For example, the NMS sends the first ICIC identifier value between the corresponding cells to the EMS through the IRP interface message with the EMS. For example, the NMS can send the identifier value in the configuration data and send it through the configuration management IRP interface message.

Step 404: The EMS modifies the stored ICIC identifier value.

For example, the EMS receives the first ICIC identification value sent by the NMS, and according to the identification value, modifies the ICIC identification value stored in itself.

Step 405: The EMS reports the modification result of the ICIC identifier value to the NMS.

For example, the EMS reports the modification result of the modified ICIC identification value to the NMS in step 404, the modified node This includes modifying the success or modifying the failure information.

Step 406: The evolved base station determines whether to perform ICIC according to the ICIC identifier.

For example, the EMS sends the first ICIC identifier value to the evolved base station, and after the evolved base station receives the first ICIC identifier value, if the first ICIC identifier value is TRUE, it indicates that the evolved base station is allowed to perform ICIC, if the first The ICIC identification value is FALSE, which means that the evolved base station is not allowed to perform ICIC, and vice versa. In another embodiment of the present invention, if the first ICIC identifier value is 1, it indicates that the evolved base station is allowed to perform ICIC; if the first ICIC identifier value is 0, it indicates that the evolved base station is not allowed to perform ICIC, and vice versa. .

In this embodiment, the order of step 405 and step 406 may be reversed or may be performed simultaneously.

In the cell management method provided by the embodiment of the present invention, the NMS first adds an ICIC identifier between adjacent cells and sets an identifier value for the ICIC identifier; the NMS notifies the EMS of the ICIC identifier value, and the EMS is modified according to the notification of the NMS. The ICIC identifier value in the EMS is sent to the evolved base station, and the evolved base station performs ICIC between the corresponding cells according to the ICIC identifier value. Centralized network management for inter-cell interference coordination at the cell level, operators and network maintenance personnel can perform coordinated and efficient inter-cell interference coordination throughout the network, whether it is the initial deployment of the network or the automatic optimization of the network operation period. Both are good.

Step 505: The evolved base station generates an ICIC modification suggestion.

For example, the EMS sends the ICIC identifier value to the evolved base station. After receiving the ICIC identifier value, the evolved base station detects and acquires the interference information of the cell edge. If the actual situation of the detected cell edge does not match the ICIC identifier value, The ICIC identification value modification suggestion may be generated. For example, if the ICIC identification requires ICIC, but the evolved base station determines that the ICIC is not required according to the interference condition of the current cell edge, a proposal to modify the ICIC identification to FALSE is generated, and vice versa.

Step 506: Report the ICIC identifier modification proposal to the NMS.

For example, the evolved base station reports the ICIC identifier modification proposal to the NMS via the EMS.

Step 507: The NMS sends the determined ICIC identifier value to the EMS.

For example, the NMS obtains the determined ICIC identification value modification result according to the ICIC identification modification suggestion of step 506, and resets the ICIC identification value according to the modification result, and notifies the EMS of the determined ICIC identification value.

In another embodiment of the present invention, step 505 to step 507 may be performed only once, or may be executed repeatedly. The number of times that the NMS performs the operation of modifying the ICIC identifier value according to the modification proposal reported by the evolved base station depends on the network situation and the operator settings. There are various implementations, and the embodiments of the present invention are different. A narrative.

Step 508: The EMS modifies the stored ICIC identifier value.

For example, the EMS modifies the ICIC identification value stored in the EMS based on the determined ICIC identification value sent by the NMS in step 507.

The manner in which a person skilled in the art can set an ICIC value by other NMSs that are not obtained through creative labor is covered by the scope of the present invention, and the embodiment of the present invention does not Limited.

If the NMS determines that ICIC needs to be performed between cells, the second ICIC identification value is set to TRUE; if the NMS determines that ICIC is not required between cells, the second ICIC identification value is set to FALSE, and vice versa. In another embodiment of the present invention, if the NMS determines that ICIC needs to be performed between cells, the second ICIC identifier value is set to 1; if the NMS determines that ICIC is not required between cells, the second ICIC identifier value is set to 0.

For example, the NMS uses the IRP interface message to implement the NMS to set the second ICIC identification value between the corresponding cells to the EMS.

Step 604: The EMS modifies the stored ICIC identifier value.

For example, the EMS receives the second ICIC identification value sent by the NMS, and modifies the ICIC identification value stored in the NRT of the EMS according to the second ICIC identification value.
