Description

User equipment access method and user equipment in multi-radio access technology

Technical field

This document relates to, but is not limited to, the field of communications, and in particular to a method and user equipment for accessing user equipment in a multi-radio access technology.

Background technique

With the continuous evolution of wireless communication technologies and standards, mobile packet services have been greatly developed, and the data throughput capability of single terminals is constantly improving. Taking the Long Term Evolution (LTE) system as an example, the downlink maximum rate of 100 Mbps data transmission can be supported in a 20 M bandwidth. In the subsequent enhanced LTE (LTE Advanced) system, the data transmission rate will be further improved. It can even reach 1Gbps.

The inflated growth of terminal data traffic has made all network resources incapable, especially in the case that next-generation communication technologies such as 3G and LTE cannot be widely deployed, and the user rate and traffic demand cannot be satisfied. The user experience is getting worse. It is predicted that the number of devices supported in the future will be 10 to 100 times higher in terms of quantity and service rate, and the end-to-end delay required for some low-latency ultra-reliable services will be shortened to one-fifth. Therefore, network development requires higher bandwidth, lower latency, higher reliability, and greater intelligence. Simple interoperability of multiple networks is not conducive to overall efficiency and user experience. New multi-networks are needed. Fusion technology.

Since the future business forms and scenarios are diversified, in order to meet various needs, there are many types of cells. In terms of network standards, there will be 2G, 3G, 4G, 5G, WLAN, in terms of coverage. There will be macro cells, micro cells, and ultra Dense Network (UDN) cells, each of which has its own characteristics. 2G, 3G, 4G, and 5G cells are cells, and the supported packet services are gradually increased with the evolution of technology; WLAN is a wireless local area network (WLAN), which is currently widely used, especially based on electrical and The 802.11 standard WLAN of the Institute of Electrical and Electronics Engineers (IEEE) adopts unlicensed spectrum and is widely used in hotspot access coverage in homes, enterprises and even the Internet. The macro cell has a wide coverage. In order to improve the system capacity, a micro cell technology is proposed, and an ultra Dense Network (UDN) is proposed. It can be seen as a further evolution of microcell enhancement technology. In the UDN network, the transmission node density will be further increased, the coverage will be further reduced, and each transmission node will serve only one or a few terminals at the same time. Therefore, how to select a network in a multiple radio access technology by a user equipment (User Equipment, UE for short) is an urgent problem to be solved.

In order to enable a person skilled in the art to more clearly understand the technical solution provided by the present invention, the access method of the user equipment in the multiple radio access technology provided by the present invention is described in detail below by using specific embodiments:

Embodiment 1

The present embodiment is a scenario in which the system characteristic information is a communication system type supported by the system, and the terminal characteristic information is a communication system type supported by the user equipment. FIG. 2 is a flowchart of the first embodiment, as shown in FIG. Includes the following steps:

201. The user equipment receives a system message sent by the network side and carries a communication system type supported by the system.
