Description

Communication control method and device

Technical field

This document relates to, but is not limited to, the field of wireless communication technologies, and in particular, to a communication control method and apparatus.

Background technique

A low power node (LPN) can be called a small base station. It usually has two deployment scenarios: hotspot deployment and enhanced coverage. In a hotspot deployment scenario, in order to achieve high data rate and spectrum efficiency, it needs to be dense in the area. A large number of small base stations are deployed. However, due to the small coverage of the small cell, the probability of a handover failure occurs when the medium and high speed mobile user equipment (UE) passes through the small base station, affecting the UE service. Continuity. In order to improve the UE mobile performance after the introduction of the small cell, the industry proposes that a base station, such as a macro base station, guarantees basic coverage, and the UE always maintains a radio resource control (RRC) connection with the base station, and the small cell only serves as a transmission. Nodes to provide higher data rates.

In this system architecture, the UE maintains a connection with at least two base stations and uses radio resources under the two base stations to implement radio resource aggregation across nodes. This architecture is usually called a dual connectivity architecture, as shown in FIG. The two base stations that are connected have a certain management control capability, which is usually called the primary base station (MeNB, Master eNB), and the other base station is called the secondary base station (SeNB, Secondary eNB); in order to support higher throughput or better The mobility, dual connectivity architecture can be extended to a multi-connection architecture in which a UE can communicate with multiple wireless access points or base stations of more than one wireless access system or network.

In a dual-connection or multi-connection architecture, the longer the UE sleeps under one base station, the more power can be saved. However, if the UE sleeps for a long time under one base station, when new service data or signaling arrives during this period, If the UE cannot be woken up in time, it will affect the user's service experience.
