Detailed Description

For ease of understanding, terms referred to in the present application will be first introduced.

1. New air interface network (New Radio, NR)

The new air interface network is a global fifth Generation Mobile Communication Technology (5G) standard based on Orthogonal Frequency Division Multiplexing (OFDM) and with a completely new air interface design, and is also a very important cellular Mobile Technology base for the next Generation, and the 5G Technology will realize ultra-low latency and high reliability. NR relates to a new wireless standard based on OFDM. OFDM refers to a digital multi-carrier modulation method. After the 3rd Generation Partnership Project (3 GPP) adopted this standard, the term NR was followed and becomes another alternative name for 5G.

2. Universal Mobile communication System (Universal Mobile Telecommunications System, UMTS)

UMTS is not limited to defining The air interface, but is also a complete third Generation Mobile Communications (3G) technology standard.

3. Evolved universal Terrestrial Radio Access Network (Evolution UMTS Terrestrial Radio Access Network, E-UTRAN)

In 3G networks, the Access Network portion is called UMTS Terrestrial Radio Access Network (UTRAN). In an LTE (Long Term Evolution) network, because of the Evolution relationship, we refer to the access network part as E-UTRAN, i.e. the mobile communication wireless network in LTE.

4. Tracking Area Update (TAU)

The TAU refers to a location area concept applied to a system of User Equipment (UE), E-UTRAN and Core network (EPC), and such a location area is called a tracking area. The EPC manages a Tracking Area (TA) registered by the UE in both the idle state and the connected state, and the UE changes registration information in the EPC when the TA changes. The TAU can tell the EPC that the UE is available.
