All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a method for performing radio resource management, where the method includes:
and 102, the first nRT RIC function management entity performs wireless resource management on the terminal accessed to the access network equipment according to the information.
In the embodiment of the invention, a first nRT RIC function management entity sends measurement information of access network equipment and/or load information of the access network equipment to a second nRT RIC function management entity; then the second nRT RIC function management entity performs wireless resource management on the terminal between access network devices according to the measurement information and/or the load information, and sends the information obtained in the wireless resource management process to the first nRT RIC function management entity; and then the first nRT RIC function management entity carries out wireless resource management on the terminal accessed to the access network equipment according to the information. Thus, in the invention, nRT RIC is divided into two parts, namely a second nRT RIC function management entity responsible for radio resource management of a terminal between access network devices and a first nRT RIC function management entity responsible for radio resource management of a terminal accessed to the access network devices, and in specific implementation, the second nRT RIC function management entity performs radio resource management on the terminal between the access network devices according to measurement information of the access network devices and/or load information of the access network devices sent by the first nRT RIC function management entity, calculates a result of the radio resource management of the terminal between the access network devices, sends information obtained according to the result to the first nRT RIC function management entity, and performs radio resource management on the terminal accessed to the access network devices according to the information by the first nRT RIC function management entity, namely, the embodiment of the invention provides a scheme for performing radio resource management through nRT RIC.
Wherein the access network equipment is a gNB or a gNB-CU.
In addition, the first nRT RIC function management entity and the second nRT RIC function management entity form an nRT RIC in the O-RAN, and are commonly used for performing radio resource management on the terminal.
The first nRT RIC function management entity and the second nRT RIC function management entity may be specific network side devices, for example, two independent processors, or two different functional blocks disposed in one processor.
Specifically, the radio resource management includes but is not limited to: power control, radio resource management channel allocation, radio resource management scheduling techniques, radio resource management handover techniques, radio resource management call admission control, radio resource management end-to-end QoS guarantee, and the like.
The power control means that the power of a transmission signal is controlled to be reduced as much as possible, the channel capacity is increased, and the battery standby time of the user terminal is increased under the condition that the communication quality is not influenced. Conventional power control techniques are based on voice services and mainly include centralized and distributed power control, open and closed loop power control, constant reception based and quality based power control. Currently, research on power control focuses on data services and multimedia services, and power control and rate control are generally performed in a comprehensive manner.
In a wireless cellular mobile communication system, there are mainly 3 channel allocation techniques involved in radio resource management channel allocation: fixed channel allocation, dynamic channel allocation, and random channel allocation.
The radio resource management scheduling technology refers to that a Scheduler (Scheduler) judges the type of the service according to the QoS requirements of users in a base station so as to allocate channel resources to different users.
The rrc handover technique refers to a Mobile terminal moving from one coverage area of a base station to another coverage area of the base station during a call, or moving out of a service area of an MSC (Mobile Switching Center) to another service area of the MSC, so as to maintain uninterrupted call for a Mobile subscriber. An efficient handover algorithm can improve the capacity and QoS of a cellular mobile communication system. Handover techniques are generally classified into hard handover, soft handover, softer handover, inter-frequency handover, and inter-system handover. The handover technique mainly uses information such as quality of network information signal, moving speed of a user, etc. as a reference to determine whether a handover operation should be performed.
The radio resource management call admission control mainly means that the call admission control mainly based on voice service decides whether to accept the call of a new user, and the call admission control algorithms currently studied can meet the requirements of the user when a base station has available resources, and mainly include the following types: a call admission control algorithm based on QoS, which classifies the accessed call services, such as real-time services and non-real-time services, and then executes different call connections for the services respectively; an interactive call admission control algorithm; a call admission control algorithm based on equivalent bandwidth; a capacity-based call admission control algorithm; a power-based call admission control algorithm; distributed call admission control algorithms, and the like.
The end-to-end QoS guarantee of the radio resource management mainly comprises the following steps: traffic policing and shaping, congestion management, congestion avoidance, admission control, and load balancing.
