Method for acquiring terminal capability in dual-connection system

Abstract

The invention discloses a method for acquiring terminal capability in a dual-connection system. The method includes: when a user terminal needs to carry out intra-system pilot frequency switching, enabling the first main base station to judge whether the target frequency point is in a frequency band combination of the current user terminal capability information or not; if the target frequency point does not exist or the frequency band combination capability information corresponding to the target frequency point is not found, acquiring a user terminal capability message to obtain corresponding frequency band combination capability information; adding the frequency band combination capability information corresponding to the measurement report or the newly obtained target frequency point to the previous user terminal capability information, bringing the information to a second main base station in a switching request, and sending a reconfiguration message to a first main base station by the second main base station according to whether to configure inter-system measurement or configuration of an inter-system auxiliary cell; and enabling the user terminal to access the second main base station and the auxiliary cell through the reconfiguration message, and establishing double connections. According to the method, on the premise of not increasing the switching delay, the target base station can quickly obtain the frequency band combination, the operability is high, and the realization is simple and effective.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for acquiring terminal capabilities in a dual connection system. Background technique [0002] With the development of electronic technology, a new generation of communication technology is constantly emerging. For operators, communication equipment based on the old generation of communication technology covers a wide range. It will take a certain amount of time for the new generation of communication equipment to gradually replace the old equipment. Therefore, In this process, there will be situations where old and new equipment provide services at the same time. In order to maximize the utilization rate of old and new equipment at the same time and improve user experience, a dual connection technology is invented and used in which the old equipment is used as the coverage layer and the new equipment is used as the capacity layer. For example, in the lat...

However, since the frequency band combination in the capability information is not the complete set of frequency band combinations supported by the terminal, the terminal capability carried in the handover request may not include the frequency band combination of the target LTE cell and its secondary NR cell

At this time, the target LTE base station cannot judge whether the NR secondary cell should be configured for the terminal based on the terminal capability.
