Description
Technical Field
The present invention relates to the field of communications, and in particular, to a device access method and apparatus.
Background
With the increasing popularity of mobile terminals such as smartphones, the traffic volume of mobile communications has experienced explosive growth in the past decade. It is generally accepted in the industry that with the emergence and popularization of new applications such as ultra-high-definition video and virtual reality, the traffic volume of mobile communication will increase exponentially in the next 10 years, and in some hot spots, will exceed 1000 times.
The 1000 times of traffic increase becomes the largest power driving further evolution of the fourth generation mobile communication system (4G system for short). To meet this demand, fifth generation mobile communication systems (abbreviated as 5G systems) present a very challenging 1000-fold capacity increase goal. The development history of mobile communication shows that cell splitting, larger bandwidth and higher spectrum efficiency are three major pillars of system capacity improvement.
With the development of Cell splitting technology, low power Transmission nodes (TPs) are deployed flexibly and sparsely in a Macro Cell coverage area, so as to form a multi-layer Heterogeneous Network (HetNet) composed of Macro cells and Small cells (Small cells). The HetNet can not only ensure the coverage, but also improve the flexibility of cell splitting and the system capacity, share the service pressure of the macro cell, and also can expand the coverage area of the macro cell. At the end of 4G system research, in order to further improve the system capacity, the 3GPP proposes a Small Cell enhancement technology, and carries out preliminary research on problems occurring when Small cells are deployed at high density.
The ultra-dense network in 5G can be seen as a further evolution of Small Cell enhancement technology. In a very dense network, the TP density will be further increased and the coverage of TPs further reduced, each TP serving only one or a few terminals at a time. Ultra-dense deployments bring the distance from the TP to the terminal closer so that their transmission power can be reduced significantly and become very close, and the difference between the uplink and downlink is therefore smaller and smaller. The TP in such an ultra-dense network employs a new Radio Access Technology (RAT), and is therefore referred to as a new RAT. Meanwhile, 5G supports three services: the method comprises the following steps that an enhanced mobile broadband service (EMBB), a massive machine type communication service (mMTC) and a low-delay ultra-reliable Connection service (Critical Connection) are different in application scenes and requirements, and may be different in processing of a physical layer and deployment of a protocol stack.
However, according to the prior art, when the device performs cell selection, it does not distinguish between a macro cell and a small cell, and selects a best cell for access, but for a new RAT of 5G, due to different deployment modes, functional protocol stacks deployed on TPs may also be different, so that some TPs may not process messages after receiving an access request of the device, which may affect access of the device.
In the related art, no effective solution has been proposed yet for the problem that the user equipment cannot select a transmission node for device access in the RAT of the 5G radio access technology.
