Problems solved by technology
Therefore, if all the CPs in the super cell are activated in real time, some CPs have little impact on UE performance but are activated in real time, which will cause waste of system resources
[0004] It can be seen that currently when providing services for UEs in the air route, since all CPs in the super cell are activated, system resources are wasted

Embodiment Construction
[0032]The basic idea of the present invention is: when receiving the MSG1 sent by the UE in the initial random access process, determine the CP corresponding to the UE in the active state according to the received power of the MSG1 detected in each CP; When the SRS sent by the UE or the signal sent by the UE on the PUSCH is received, the corresponding CP in the active state of the UE is adjusted according to the received power of the SRS or the signal sent by the PUSCH detected in each CP.
[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0034] The present invention provides a method for controlling the activation state of a CP in a super cell, such as figure 1 shown, including the following steps:
[0035] Step 101: The evolved base station (eNB, evolved Node B) judges whether it has received MSG1 sent by any UE during the initial random access process, and if so, executes ste...

The invention discloses a method for controlling an activation state of a cell portion (CP) in a super cell. The method comprises the following steps: when a first piece of information (MSG1) transmitted from a user equipment (UE) in an initial random access process is received, determining the CP in the activation state, which corresponds to the UE according to a received power of the MSG1 detected in each CP; when a sounding reference signal (SRS) transmitted by the UE or a signal transmitted by the UE on a physical uplink shared channel (PUSCH) is received, adjusting the CP in the activation state, which corresponds to the UE according to a received power of the signal on the SRS or PUSCH detected in each CP. The invention further discloses a device for controlling the activation state of the CP in the super cell; by adopting the invention, when a service is provided for the UE in an airline, some CPs in the super cell are in the activation state, so that the system resources are saved.
Description
technical field [0001] The present invention relates to cell management technology in the field of mobile communication, in particular to a method and device for controlling the activation state of some cells (CP, Cell Portion) in a super cell. Background technique [0002] When the aircraft is flying in the airway, the user needs to use satellite communication for communication, but the capacity of satellite communication is limited and the price is high. Therefore, the idea of using the ground mobile communication system to cover the air route is currently proposed to provide services for user equipment (UE, User Equipment) flying in the air route, so that greater communication capacity and lower cost can be provided. price. If you want to use the ground mobile communication system to cover the air route, you need to overcome the problem of fast switching between cells caused by the high-speed flight of the aircraft, so it is most suitable to use the super cell technolo...
