Description

SCG (cell group signature group) deactivation configuration method and device and access network equipment

Technical Field

The present application relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for configuring SCG deactivation of an auxiliary cell group, and an access network device.

Background

In a New air interface technology (5th Generation New Radio, 5G NR) system of the fifth Generation mobile communication technology, in order to improve the data transmission rate, a network side may configure a Secondary Cell Group SCG (also called a Slave Cell Group or a Standby Cell Group) for a terminal (User Equipment, UE) to perform load sharing, so as to improve the data transmission rate of the UE. After the network configures the SCG for the UE, the UE accesses a Secondary base Station (SN) to a Primary Cell (PSCell) of a Secondary Cell group of the SCG. The network side may configure bearer transmission for the UE in the SCG, and the UE simultaneously maintains configuration information of a Master Cell Group MCG (also called Primary Cell Group or Main Cell Group or Controller Cell Group) and the SCG.

The NR R17 project will introduce SCG deactivation. The SCG deactivation is equivalent to SCG sleep state (dormant), SCG suspend (suspend), PSCell suspend or sleep state, PSCell deactivation state, etc., and aims to suspend SCGs for infrequent large data streams when there is no large data packet transmission or there is no data transmission on the SCG side, and the UE and the network side save the context of SCGs and suspend some behaviors, such as the UE stopping monitoring the Physical Downlink Control Channel (PDCCH) on the SCG side and stopping data transmission on the SCG side, so as to save the power consumption of the UE; when there is a large data stream interaction or when there is data transmission on the SCG side, the SCG of the UE is activated quickly to resume the data transmission.

Therefore, a scheme for configuring the SCG deactivation for the UE by the network side needs to be provided.

In The 5G NR system, in order to achieve a higher transmission rate and a lower transmission delay, a DUal Connectivity (DC) technique is introduced by The 3rd Generation Partnership Project (3 GPP). The DC technology means that a single User Equipment (UE) can simultaneously establish communication links with two base stations (a Main base station MN and an auxiliary base station SN), respectively, and the MN (Master Node, also called Primary Node, Main Node, or Controller Node) and the SN (Secondary Node, also called Slave Node, or Standby Node) can respectively belong to different systems or the same system, and perform uplink and downlink communication with the UE through dual communication links, thereby implementing higher-rate data transmission and lower delay, and improving the performance of the wireless communication system.

The dual communication link can better utilize radio resources compared to the single communication link. In a specific implementation, the uplink user Data may be distributed at the terminal side and then sent to two base stations (MN and SN), and finally merged at a Data link Protocol (PDCP) layer of the main base station MN and sent to the core network.

As shown in fig. 1, the method is applied to a master base station MN, and includes:

step 101, receiving target indication information of a target auxiliary base station SN; the target SN is a SN configured by the target UE with double connection or multi-connection, or the MN is preset as the SN configured by the UE;
