Problems solved by technology

[0003] The existing traditional communication network for relatively limited application scenarios adopts a simple architecture with a single wireless access network and a fixed configuration of core network functions. This architecture cannot meet the application requirements and performance requirements of all scenarios.
However, if a private network is built for each scenario to meet customized application and performance requirements, it will cause a lot of waste of infrastructure or spectrum resources.

Embodiment 1

[0071] see image 3 , an embodiment of the present invention provides a method for constructing a wireless access network slice, the method comprising:

[0072] S101. The primary base station and adjacent secondary base stations in the core network and radio access network share an initial default process through the interface, and build an end-to-end matching association relationship of network slices.

[0073] It should be noted that based on the public initial default process of the interface between CN and RAN, the core network and all base stations under its jurisdiction perform end-to-end initial construction and matching association of network slices to form their own public initial default or proprietary multiple CNSlices and the division of multiple RAN Slices, so the corresponding network functions and network resource configurations are also determined accordingly.

[0074] S102. The UEs of the terminal group report their respective Slice IDs or MDD information to ...

Embodiment 2

[0092] Based on the same technical concept as the foregoing embodiments, this embodiment describes the technical solutions of the foregoing embodiments in detail through a specific process of constructing a network slice in a base station of a radio access network. The following will give three processes of using the four base stations of NG-Core, eLTE eNB, NR gNB1 and NR gNB2 to perform multi-connection data transmission operations:

specific Embodiment 1

[0093] see Figure 4 , NG-Core is divided into enhanced bandwidth data transmission services (eMBB, Enhanced Mobile Broadband), ultra-reliable and low-latency communication (URLLC, Ultra Reliable Low Latency Communication) according to the type of business, and massive and huge machine type Internet of Things terminal communication (mMTC , Massive Machine Type Communication) three core network slices (CN Slice), respectively NG-Core Slice1, NG-Core Slice2, NG-Core Slice3. The eLTE eNB with the largest wireless signal coverage is used as the main base station, and there is no reconfiguration division of any dedicated radio access network slice (Dedicated RAN Slice), that is, there is only one public radio access network slice (Common / Default RAN Slice). NR gNB1 with small wireless signal coverage can be used as a secondary base station for data offloading. It is internally configured and divided into a Common / Default RAN Slice and three Dedicated RAN Slices, corresponding to eM...

Abstract

Embodiments of the invention disclose a construction method and device for a wireless access network slice which are applied to a main base station of a wireless access network. The method includes the following steps: end-to-end corresponding relationship of the network slice is constructed by the main base station and an adjacent auxiliary base station in the wireless access network and a core network, wireless access network slice RAN Slices information of the main base station and the adjacent auxiliary base station is determined according to the end-to-end corresponding relationship of the network slice; slice identification Slice ID or multidimensional attribute description identification MDD information reported by all terminal groups UEs served by the main base station are countedby the main base station, the distributive amount of slice resources required for constructing the RAN Slices by itself is obtained, the main base station sends reconstruction request information of the RAN Slice slice to the adjacent auxiliary base station according to the distributive amount of slice resources required for constructing the RAN Slices by itself. The main base station performs multi-connection data transmission reconfiguration on the terminal group UEs served by the main base station through RRC messages according to received reconfiguration reply information sent by the adjacent auxiliary base station.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for constructing a wireless access network slice. Background technique [0002] In today's era of comprehensive informationization, the demand for business data transmission applications in all walks of life has shown explosive growth. Compared with traditional 3G and 4G mobile communication systems, the application scenarios for 5G systems are very different.
