Description

Method and device for accessing terminal to user plane of centralized unit in balanced manner
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for enabling a terminal to access a user plane of a central unit in a balanced manner.
Background
With the development and popularization of the 5G technology, the 5G technology is applied to more and more fields. In the 5G technology, the available capacity of the user plane of the centralized unit directly affects the effectiveness of 5G data storage, and therefore, it is particularly important to accurately calculate the available capacity of the user plane of the 5G centralized unit.
When calculating the available capacity of the user plane of the 5G centralized unit, the available capacity of the user plane of the 5G centralized unit cannot be calculated according to the method for calculating the available capacity of the user plane of the centralized unit in the 4G because the quality of service (QoS) framework of the 5G is greatly different from that of the 4G. In the 4G quality of service framework, end-to-end of the concentrated unit user plane with the base station, the base station with the core network, and the concentrated unit user plane with the core network are managed according to bearer granularity. However, in the quality of service framework of the 5G centralized unit user plane, referring to fig. 1, there are two granularities of PDU session (protocol data unit session) and QoS flow (quality of service flow) between the base station and the core network, one PDU session contains multiple QoS flows, and each PDU session establishes an N3 tunnel between the base station and the core network. Between the terminal and the base station, there are two granularities of wireless data bearer and QoS flow, a PDU session is split into one or more wireless data bearers over the air interface, a wireless data bearer may contain multiple QoS flows, and the PDU session becomes invisible between the terminal and the base station.
However, currently, when calculating the available capacity of the user plane of the 5G centralized unit, the available capacity of the user plane of the 5G centralized unit is generally divided into several categories, such as a CPU (controller) main frequency, a memory, and a transmission network resource, and is not distinguished for several interfaces, such as an interface between the user plane of the centralized unit and a core network (N3 interface), an interface between the user plane of the centralized unit and a user end node (F1-U interface), and an interface between the user plane of the centralized unit and an adjacent base station (Xn-U interface), and does not consider the resource dimensions, such as PDU session number and radio data bearer number, and cannot accurately reflect the available capacity of the user plane of the 5G centralized unit.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, specific embodiments of the present application will be described in detail with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present application are shown in the drawings. Before discussing exemplary embodiments in greater detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
The method and the device for accessing the terminal to the user plane of the centralized unit in a balanced manner aim to improve the calculation accuracy of the available capacity of the user plane of the 5G centralized unit by receiving the first available capacity which is reported by the user plane of the first centralized unit and comprises the N3 bandwidth available capacity value, the F1 bandwidth available capacity value and the Xn bandwidth available capacity value of the user plane of the centralized unit in the current statistical period when the fixed new terminal is accessed. And, the first centralized unit user plane with the available capacity meeting the preset conditions is determined, so that the access rationality of the new terminal can be improved. Compared with the conventional new terminal access mode, when the available capacity of the user plane of the central unit is calculated, the available capacity of the user plane of the 5G central unit cannot be accurately reflected because the available capacity of the user plane of the central unit is generally classified into several categories such as a CPU (controller) main frequency, a memory, transmission network resources and the like, and the available capacity of the user plane of the 5G central unit is not distinguished according to several interfaces such as an interface (N3 interface) between the user plane of the central unit and a core network, an interface (F1-U interface) between the user plane of the central unit and a user end node, and an interface (Xn-U interface) between the user plane of the central unit and an adjacent base station. Therefore, the method for accessing the terminal to the user plane of the centralized unit in a balanced manner is provided to solve the problem that the available capacity of the user plane of the existing 5G centralized unit is low in calculation accuracy.
Fig. 2 is a flowchart of a method for enabling a terminal to access a centralized unit user plane in a balanced manner according to an embodiment of the present application, where the method for enabling the terminal to access the centralized unit user plane in a balanced manner provided in this embodiment may be executed by a device for enabling the terminal to access the centralized unit user plane in a balanced manner, the device for enabling the terminal to access the centralized unit user plane in a balanced manner may be implemented in a software and/or hardware manner, and the device for enabling the terminal to access the centralized unit user plane in a balanced manner may be formed by two or more physical entities or may be formed by one physical entity. Generally, the device for equalizing the access of the terminal to the user plane of the centralized unit can be a terminal device, such as a computer device.
The following description will be made by taking a computer device as an example of a main body for executing a method for accessing a terminal to a user plane of a central unit in a balanced manner. Referring to fig. 2, the method for enabling a terminal to access a centralized unit user plane in a balanced manner specifically includes:
s101, when a new terminal is accessed, determining available capacities of a plurality of centralized unit user planes according to available capacity information reported by the plurality of centralized unit user planes, wherein the available capacity information is obtained by reporting a first available capacity by a first centralized unit user plane, the first available capacity is obtained by performing operation processing on terminal data of all accessed terminals by the first centralized unit user plane, and the first available capacity comprises an N3 bandwidth available capacity value, an F1 bandwidth available capacity value and an Xn bandwidth available capacity value of the centralized unit user plane of a current statistical period.
The 5G independent networking base station generally includes a Baseband Base Unit (BBU) and a radio frequency processing Unit (RRU), and in order to save hardware cost and implement flexible deployment and coordination management of a station, the Baseband Base Unit (BBU) further divides a protocol stack of the base station by adopting a manner of separating a Central Unit (CU) from a Distributed Unit (DU). The centralized unit includes a centralized unit user plane (CU-UP) and a centralized unit control plane (CU-CP). One control plane of the central unit in the central unit can correspond to a plurality of user planes of the central unit, and the balanced service bearing of the user planes of the central units is very critical to the stable operation of the whole central unit.
In a scenario where a hub control plane interfaces multiple hub user planes, one hub user plane may access multiple terminals, and a PDU session, radio data bearer, and QoS flow to which a terminal belongs are only handled in a certain designated hub user plane. The control plane of the central unit can timely know the load state of the corresponding user plane of the central unit through the available capacity information reported by the user plane of the central unit, and then, one user plane of the central unit is distributed for a new terminal which is initially accessed to the base station to process the PDU session, the wireless data bearer and the QoS flow subordinate to the new terminal through the method for balancing and accessing the terminal to the user plane of the central unit. The new terminal may be switched to access through Xn connection, restored to access across stations in an inactive state, reestablished to access across stations, or established to access through dual connection.
The present embodiment is described with the control plane of the central unit as the main body. Under the scene that one centralized unit control plane is connected with a plurality of centralized unit user planes, the plurality of centralized unit user planes report the available capacity information of the plurality of centralized unit user planes to the centralized unit control plane at random. When a new terminal needs to be accessed, the control plane of the central unit determines the available capacity of the user planes of the plurality of central units which are currently docked according to the available capacity information reported last time before the current time of the user planes of the plurality of central units which are docked.

In one embodiment, the second available capacity includes a network bandwidth available capacity value of the centralized unit user plane of the last statistical period, and the first available capacity includes a network bandwidth available capacity value of the centralized unit user plane of the current statistical period. The network bandwidth available capacity values include an N3 bandwidth available capacity value, an F1 bandwidth available capacity value, and an Xn bandwidth available capacity value, where the N3 bandwidth available capacity value includes a bandwidth available capacity value of an interface of the hub unit user plane interfacing with the subscriber units of the core network, the F1 bandwidth available capacity value includes a bandwidth available capacity value of an interface of the hub unit user plane interfacing with the distribution units, and the Xn bandwidth includes a bandwidth available capacity value of an interface of the hub unit user plane interfacing with the neighbor base stations.
