Mobile network service adaptation method, device, terminal, base station and mobile communication system

Abstract

The invention discloses a mobile network service adaptation method, a device, a base station and a mobile communication system, and relates to the technical field of mobile communication. The method comprises the steps of a base station receiving an RRC message from a terminal, wherein the RRC message comprises one or more pieces of NAS PDU information; the base station determining the slice typeaccording to the format type of the NAS PDU information, and determining a core network entity based on the mapping relation between the pre-configured service slice and the core network entity; the base station generating a service establishment request message or an uplink data indication message, and sending the messages to a core network entity corresponding to the slice type, so that the corenetwork entity allocates resources for acceptable services. According to the method, device, terminal, base station and system, the base station determines a core network entity for bearing the services through the NAS PU in a service establishment request message, and directly sends the service establishment request message to the core network entity carrying the services. The service establishment time delay is reduced, the core network signaling is reduced, and the service establishment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a mobile network service adaptation method, equipment, terminal, base station and mobile communication system. Background technique [0002] Mobile communication technology has now developed to the fifth generation (5G, 5 th Generation). Considering that there are obvious differences in the service characteristics of different services, such as delay, rate, jitter, etc., and there are also obvious differences in the resource requirements of various services for the network, for mobile networks, if all functions are supported, its design The price and deployment cost are relatively high. [0003] To this end, the 5G phase will introduce the function of NFV (Network Function Virtualization, Network Function Virtualization) to the core network to support various services and reduce deployment costs. In the current 3GPP (The 3rdGeneration Partnership Project, 3rd Gen...

AI Technical Summary

Problems solved by technology

[0007] (1) The core network signaling is wasted, and the service establishment delay is long: the current solution adopts the method of transferring to the default core network, which will cause the service request to be resent twice, resulting in a waste of core network signaling resources, and business increase in setup delay

From this perspective, the current solution cannot meet the low-latency requirements of 5G;

[0008] (2) The base station lacks fine-grained identification of services: Due to the principle of LTE, the base station side does not parse NAS PDU messages, so the base station side cannot know the content of the service request of the terminal, and can only configure services according to the instructions of the core network

In this case, it is impossible to select the appropriate core network resources and routing configuration for the business;

[0009] (3) The base station lacks the corresponding relationship between the core network and service slices: due to differences in core network nodes and resources required by different services

However, in the existing mechanism, the base station side lacks the mapping relationship between service resources and core network resources, and the core network information can only be manually configured, which increases the configuration workload during deployment.
