detailed description

In a mobile communication network, a layered management method is generally adopted to manage devices (network elements) in the entire communication network. Generally, there are different levels of management systems such as NMS and EMS. EMS mainly completes the network element management layer (EML) function in ITUTMN, that is, completes the management function of one or more mobile communication devices (network elements), and the managed network elements generally come from the same equipment supplier. NMS mainly completes the network management layer (NML) function in ITUTMN, and is responsible for the management of all network elements in a managed network. The interface between the NMS and the EMS is called the northbound interface (Itf-N). The operator generally communicates with the EMS through the northbound interface on the NMS to manage equipment and related functions of different manufacturers.

From the perspective of 3GPP specifications, the northbound interface processing function at the NMS layer is called IRPManager, and the northbound interface processing function at the EMS layer is called IRPAgent. For specific definitions of IRPManager and IRPAgent, please refer to the 3GPP specification "TS32.1503rdGenerationPartnershipProject; TechnicalSpecificationGroupServicesandSystemAspects; Telecommunicationmanagement; IntegrationReferencePoint (IRP) Concept and definitions". Therefore, when the NMS interacts with the EMS through the northbound interface, the NMS actually passes through the IRPManager first, and the IRPManager interacts with the IRPAgent through the northbound interface, and the IRPAgent is then passed to the EMS. vice versa.

For simplicity, this patent uses NMS and EMS for description, but in the actual process, as mentioned above, IRPManager and IRPAgent are involved.

Simply relying on energy-saving algorithms for energy-saving management cannot take into account the environment and operating conditions of the base station, and the resulting energy-saving solution is not optimized. Therefore, it is necessary for upper-layer equipment to manage and adjust this process. There is currently no such energy-saving management system. management mechanism.

In order to solve the above problems, an embodiment of the present invention provides an energy-saving management method, which can perform planning and analysis according to the network distribution, and then delineate a certain energy-saving area according to the planning result, and form an energy-saving combination of base stations in this area. And divide the work of base stations in this area, determine the base stations that need to enter the energy-saving state or the base stations that need to provide compensation coverage, and configure the energy-saving combination information to the base station or EMS through the northbound interface.

First, Embodiment 1 of the present invention will be described in detail.

Embodiment 1 of the present invention provides an energy-saving management method, which is added to the management scope in units of energy-saving combinations. In the embodiment of the present invention, the energy-saving management command is specifically an energy-saving combination adding command. The specific process is shown in Figure 1. include:

Step 101, the NMS generates an energy-saving combination adding command, and the energy-saving combination adding command carries energy-saving combination information;

The energy-saving combination refers to a collection of base stations that participate in energy-saving operations when the traffic volume in an area drops. Planning and analysis based on the geographical environment and user conditions of the region, and pre-designating a set of base stations that jointly participate in energy-saving operations will be of great help to improve the efficiency and effect of energy-saving algorithms.

After the base stations in the area to be managed are divided into an energy-saving group, the energy-saving group can be added to the management range for management.

In this step, the NMS generates an energy saving management command according to the determined energy saving combination, specifically an energy saving combination adding command. The energy-saving combination adding command carries energy-saving combination information, including an energy-saving combination identifier and a list of base stations. The energy-saving group identifier is generally an energy-saving group number (ESGroupNo), and optionally, it can also be an energy-saving group name (ESGroupName).

Optionally, the management personnel may also configure the energy saving management command, issue the energy saving management command to the NMS, and the NMS issues the energy saving management command to the EMS.

The base station list records the identities of all base stations in the energy-saving combination.

Step 102, the NMS sends the energy-saving combination add command to the EMS, instructing the EMS to manage the energy-saving combination according to the energy-saving combination information;

In this step, the NMS sends an energy-saving combination adding command to the EMS through the northbound interface.

Step 103, the EMS manages the energy-saving combination according to the energy-saving combination adding command;

Here, the energy-saving group number (ESGroupNo) is an integer type, the value is 1, 2, 3, ..., each energy-saving group has a unique number; the energy-saving role (ESRole) is an enumeration type, the value For "energy saving", "compensation", "compensation standby", etc., here "energy saving" means that the base station enters the energy saving state, that is, the shutdown or sleep state, and "compensation" means that the base station enters the compensation state, that is, increasing its own coverage by increasing power and other means range to compensate for the coverage of the base station in the energy-saving state. "Compensation backup" means that the base station performs the compensation function instead of the base station set to the "compensation" state when the base station fails to work normally.

In addition, variables for recording the energy saving group number (ESGroupNo) and the energy saving role (ESRole) are added in each base station.

In this step, after receiving the energy-saving combination addition command sent by the NMS, the EMS stores the energy-saving combination information in the command in the local energy-saving configuration information storage area.
