In the coming 5G network technology, ultra-dense networking is a key networking technology for 5G, and as the number of cells and users increases sharply, interference between cells increases, and at this time, the traditional networking structure inevitably has difficulty in ensuring network performance of users at the edge of the cells, realizing cell load balancing, and suppressing interference between cells. In addition, the traditional cell networking mode uses a cell as an identifier, needs a large amount of manual configuration of cell parameters, and has the defects of low networking efficiency and high system cost.

In order to achieve the purpose, the technical scheme of the invention is realized as follows:
a user-centric cell networking method, comprising the steps of:
s1. establishing cached cell parameter configuration table in the 5G macro base station;
the UE accesses the network and establishes RRC connection with the network;
ue sends terminal information including but not limited to location and QoS requirements to the network;
s4. the macro base station of 5G determines whether the cell parameter configuration table cached by the macro base station has configuration information matching the terminal information based on the terminal information sent by the UE, if yes, step s7 is executed, and if no, step s5 is executed;
s5. the 5G macro base station calculates the network resource needed by the UE according to the terminal information sent by the UE, and coordinates the governed AP to allocate the network resource for the UE;
s6. storing the terminal information sent by UE and the network resource information distributed to the UE into the cell parameter configuration table;
s7. according to the configuration information in the cell parameter configuration table, the UE is directly networked according to the configuration information matched with the cell parameter configuration table subsequently, and a cell network taking the user as the center is obtained.
Further, the terminal information sent by the UE also includes UE type information.
Further, the QoS requirement information includes 5QI, ARP, reflection QoS attribute, guaranteed stream bit rate, maximum stream bit rate, indication control, and maximum packet loss rate.
Further, in step s5, the 5G macro base station communicates with the subordinate AP through the X2 interface, and performs interaction and calculation through the coordinated multipoint transmission technology, so as to allocate antenna and RB resources to the UE.
Further, the APs that allocate network resources to the UE are a plurality of APs distributed around the location of the UE.
Compared with the prior art, the invention has the following advantages:
the cell networking method taking the user as the center stores the terminal information sent by the UE and the network resource information distributed to the UE into the cell parameter configuration table through the established cell parameter configuration table, so that the subsequent UE can directly perform networking according to the configuration information matched with the cell parameter configuration table, thereby reducing the networking calculation amount, further improving the networking efficiency and reducing the system networking cost.
In addition, the cell networking method of the invention enables the 5G macro base station to communicate with the subordinate AP through an X2 interface, and utilizes the coordinated multi-point transmission technology to allocate network resources, thereby solving the problem of inter-cell interference caused by the increase of accessed UE and reducing the influence on the system capacity.

Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
Meanwhile, the terms involved in the present embodiment are understood by the common expressions of the present invention in the field, and the operations involved in the present embodiment can be performed by the conventional technical means in the field.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
The embodiment relates to a cell networking method taking a user as a center, which can be used in a 5G network under ultra-dense networking so as to effectively improve the user network use experience and the efficiency of a network system.
In terms of overall design, the cell networking method of this embodiment includes the following steps:
step s 1: establishing a cached cell parameter configuration table in a 5G macro base station;
step s 2: the UE accesses a network and establishes RRC connection with the network;
step s 3: the UE sends terminal information including but not limited to location and QoS requirements to the network;
step s 4: the 5G macro base station judges whether the cell parameter configuration table cached by the macro base station has configuration information matched with the terminal information or not based on the terminal information sent by the UE, if yes, the step s7 is carried out, and if no, the step s5 is carried out;
step s 5: the 5G macro base station calculates network resources required by the UE according to the terminal information sent by the UE, and coordinates an administered AP to allocate the network resources to the UE;
step s 6: storing terminal information sent by UE and network resource information distributed for the UE into the cell parameter configuration table;
step s 7: and according to the configuration information in the cell parameter configuration table, the UE is enabled to perform subsequent networking directly according to the configuration information matched with the cell parameter configuration table, and a cell network taking the user as the center is obtained.
The structure of the cell networking network obtained by the above method is shown in fig. 1, and in fig. 1, the abbreviation gNodeB stands for a 5G macro base station, AP stands for a wireless access device, and UE stands for a terminal.
In the above method, the terminal information sent by the UE may further include UE type information in addition to the terminal location information and the QoS requirement information thereof. Also, in general, the QoS requirement information described above in this embodiment includes 5QI, ARP, Reflection QoS Attribute (RQA), guaranteed stream bit rate (GFBR), maximum stream bit rate (MFBR), indication control, and maximum packet loss rate.
In the present embodiment, in the step s5, when the network resource is allocated to the UE, the macro base station 5G is specifically adopted to communicate with the subordinate AP through the X2 interface, and perform interaction and calculation through the coordinated multipoint transmission technology, so as to allocate the antenna and RB resource to the UE. At the moment, the 5G macro base station can dynamically configure parameters according to the terminal requirements and the change of the network environment, so that the load balance among cells can be effectively controlled, the interference among the cells is reduced, the network quality of the terminal is ensured, and the networking is more flexible.
In addition, in the overall network system, as the number of access points and terminals increases to a certain extent, the interference between cells inevitably affects the network system capacity. In this embodiment, the 5G macro base station communicates with the subordinate AP through the X2 interface, and allocates network resources by using the coordinated multi-point transmission technology, so that the problem of inter-cell interference caused by the increase of the number of UEs accessing the macro base station can be solved, and the influence on the system capacity can be reduced.
In addition, when the terminal information sent by the UE and the network resource information allocated to the UE are stored in the established cell parameter configuration table, the system will dynamically update the table. As the terminal configuration information stored in the cell parameter configuration table is continuously increased, more and more terminal users directly perform networking according to the matched configuration information in the table when the data is accumulated to a certain degree, and thus, cell networking is realized.
It should be further noted that, as shown in fig. 1, in this embodiment, the AP that allocates network resources to the UE is also configured to be multiple APs distributed around the location of the UE, so that each UE can be served by multiple APs in a combined manner, and thus, the network coverage effect on the terminal can be ensured, and the network use experience of the terminal user is improved. And more importantly, the method can also effectively solve the problem of insufficient coverage of the cell edge network, and can provide better service for cell edge terminal users.
In this embodiment, through the established cell parameter configuration table, the terminal information sent by the UE and the network resource information allocated to the UE are stored in the cell parameter configuration table, so that the subsequent UE can directly perform networking according to the configuration information matched with the cell parameter configuration table, so as to obtain a network structure with the user, i.e., the terminal, as the center.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
