Problems solved by technology
[0004] However, the above-mentioned cell activation scheme is based on the network architecture of LTE. Under this network architecture, the access network of LTE is only composed of base stations, that is, the base stations are integrated base station type
Since the access network convergence unit (Radio Access Network Convergence Unit, RANCU) and the distribution unit (Distribution Unit, DU) in the cloud radio access network (Cloud Radio Access Network, CloudRAN) are separated, this integrated base station The type of base station cannot be applied to the cloud radio access network (Cloud Radio Access Network, CloudRAN), which makes the existing cell activation scheme unable to adapt to the CloudRAN network architecture

The present application discloses a cell activation method and related equipment, which can provide a cell activation solution adapted to the CloudRAN network architecture. The application method includes: the access network convergence unit RANCU sends a first message to the distribution unit DU, the first message is used to apply for equipment resources on the DU for the target cell to be activated, the first message carries the identity of the target cell, and the RANCU At least one base station is deployed; the RANCU receives the second message sent by the DU, the second message is for the DU to determine the target wireless configuration information and target device information of the target cell according to the identifier, and assign the target device to the target cell according to the target wireless configuration information and target device information After resources, the message sent to RANCU, the wireless configuration information and equipment information of at least one cell is stored on DU, and the second message is used to indicate to RANCU that the target device resource has been applied for the target cell; RANCU sends to DU according to the second message The activation request of the target cell, so that the DU activates the target cell according to the activation request.
Description
technical field [0001] The present application relates to the field of communication technologies, and in particular to a cell activation method and related equipment. Background technique [0002] The network architecture of Long Term Evolution (LTE) defined by the Third Generation Partnership Project (Third Generation Partnership Project, 3GPP) agreement can be found in figure 1 ,exist figure 1 Among them, the access network of LTE is only composed of evolved base stations (evolved Node B, eNodeB) (hereinafter referred to as base stations). , namely grid network structure. Each base station is respectively connected to a mobile management entity (Mobile Management Entity, MME) or a serving gateway (Serving GateWay, S-GW) through an S1 interface. Each base station is deployed on a dedicated baseband unit (Baseband Unit, BBU), for example, eNodeB1 is deployed on BBU1, and eNodeB2 is deployed on BBU2. [0003] Based on the above network architecture, an existing cell acti...
