Background technique

LTE (Long Term Evolution, long-term evolution network) is an evolution standard based on the UMTS network formulated by the 3GPP (Third Generation Partnership) organization. LTE greatly improves the transmission capability of the physical layer and reduces the complexity of the system. LB (Load balancing, load balancing) means that one of the two systems or two cells with a heavier load transfers part of the load to the other to achieve a state of evenly distributed load. Load balancing can improve the utilization of wireless resources in the overall network, expand system capacity, and provide users with diversified services and better service quality.

In an actual network, when the load between cells is unbalanced, it may cause cell load congestion, the QoS (Quality Of Service, Quality of Service) of UE (User Equipment, user equipment) service will decrease, the probability of call drop will increase, and the user access The decline of the success rate, and the reduction of the total capacity of the system. The purpose of LB is to discover such unbalanced load scenarios as much as possible, and gradually adjust the difficulty of inter-cell handover or reselection, while ensuring that the handover success rate and call drop rate remain unchanged or increase, so that in the cell The services in the edge overlapping area should be located in the cell with light load as much as possible, so as to reduce the probability of occurrence of unbalanced load among cells.

In order to better implement load balancing between cells at the cell level, a network management system can be provided to control the LB relationship between cells from the perspective of a network management system. However, there is currently no network management method for LBs between neighbors.

A cell management method according to an embodiment of the present invention includes: sending a message including an LB identification value to an EMS, and the LB identification value is used to indicate whether LB between adjacent cells is allowed.

In the embodiment of the present invention, the centralized network management of inter-cell load balancing at the cell level is realized by sending a message to the EMS that includes the LB identification value, and the LB identification value is used to indicate whether to allow the execution of LB between adjacent cells. .

In the embodiment of the present invention, by receiving the message containing the LB identification value and modifying the stored LB identification value according to the message, centralized network management of inter-cell load balancing is realized at the cell level.

As shown in Figure 2, the embodiment of the present invention also provides a cell management method, including:

S201. Receive a message including an LB identification value, where the LB identification value is used to indicate whether LB between adjacent cells is allowed;

S202. Determine whether to perform LB between adjacent cells according to the LB identifier value.

In the embodiments of the present invention, by receiving the message containing the LB identification value and determining whether to perform LB between adjacent cells according to the identification, centralized network management of inter-cell load balancing can be realized at the cell level.

The embodiment of the present invention manages the network element side through the network side. In the embodiment of the present invention, the LB identification value is first added between adjacent cell relations, for example, the LB identification value added in NRT (Neighbor Relation Table, neighbor relation table), the NRT may be 3GPP E-UTRAN (evolved IOC (Information Object Class) EUtranRelation in the UMTS Terrestrial Radio Access Network) network resource model; after adding the identifier, set the attribute value for the LB identifier value, for example, set the first attribute value to indicate that execution between cells is allowed LB, and a second attribute value different from the first attribute value are used to indicate that LB is not allowed between cells, for example, they can be set as TRUE and FALSE, or 1 or 0 respectively. In the embodiment of the present invention, mode 1 is taken as an example for illustration; the NMS sets the LB identification value and notifies the EMS, and then the EMS notifies the base station of the LB identification value, and the base station judges whether to perform LB according to the LB identification value. .

In order to better understand a cell management method provided by the embodiment of the present invention, the NMS and EMS involved in the embodiment of the present invention are now introduced.

The embodiment of the present invention manages the network element side through the network side, and the network side includes two entities: NMS and EMS, wherein, the NMS mainly completes the ITU TMN (International Telecommunications UnionTelecommunications UnionTelecommunications Management Network, International Telecommunication Union Telecommunication Management Network) The network management layer (NML, Network Management Layer) function provides network-oriented operation and management functions, and EMS completes the network element management layer (EML, Element Management Layer) function in ITUTMN, that is, completes device-oriented operation and maintenance functions.

The interface between the NMS and the EMS is called an Itf-N interface (Interface-N interface, that is, a northbound interface). In the Itf-N interface, some integration reference points (IRP, Integration Reference Point) are defined, such as basic configuration management IRP, batch configuration management IRP, and notification IRP. Through the functions provided by these integrated reference points, the operation and maintenance functions of the network are completed. The base station and the EMS can communicate directly, and the base station and the NMS can communicate directly through the northbound interface. At this time, the EMS is embedded in the base station, or the base station communicates with the NMS through the EMS.

The cell management method provided by the embodiment of the present invention is applicable to systems such as LTE, UMTS, GSM, and WiMaX systems.

In the cell management method provided by the embodiment of the present invention, the NMS adds the LB identification value in the IOCEUtranRelation in the 3GPP E-UTRAN. For example, an attribute field may be added in the IOC EUtranRelation, and the attribute field is used as the LB identification value.

The LB identification value is used to identify whether to allow LB between cells, for example, the attribute field may be isLBAllowed, and the format of the isLBAllowed attribute field is shown in Table 1.

Table 1. IOC EUtranRelation table in 3GPP E-UTRAN

LB support in Table 1 indicates whether the attribute isLBAllowed supports LB management; readability indicates whether the content of the isLBAllowed attribute field is readable; writability indicates whether the content of the isLBAllowed attribute field can be modified; M in the table Indicates that the isLBAllowed attribute field must have corresponding bytes.

If the NMS judges that LB needs to be performed between cells, set the LB identification value as the first attribute value; if the NMS determines that LB does not need to be performed between cells, set the LB identification value as the second attribute value.

After setting the attribute value of the LB identification value, the NMS sends the LB identification value between the corresponding cells to the EMS through the IRP interface message between the NMS and the EMS. For example, the identification value can be placed in the configuration data, and through the configuration management IRP interface message sent.

After the base station receives the LB identification value, if the LB identification value is the first attribute value, it means that the base station is allowed to perform LB, otherwise, the LB is not performed, or, when When the LB identifier value is the first attribute value, the base station may also determine that LB does not need to be performed according to actual cell edge load conditions, and then LB is not performed.

In this embodiment, the base station may also feed back the result of determining whether to perform load balancing to the EMS.
