A tdd/fdd network interoperability processing method and base station

Abstract

Embodiments of the present invention provide a TDD / FDD network interoperability processing method and a base station. The method includes: obtaining the current service type of the user terminal and the network where the user terminal currently resides; if it is judged that the current residency network is inconsistent with the target network corresponding to the current service type, then according to the uplink control channel parameters, estimate The uplink frequency offset of the user terminal; if it is determined that the uplink frequency offset of the user terminal is greater than the first preset threshold, then acquire the network performance parameters of the target network; if it is determined that the network performance parameters of the target network meet If the preset condition is met, the user terminal is switched to the target network. The base station is used to execute the above method. The method and the base station provided by the invention improve the network quality of the user terminal of the high-speed rail private network.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a TDD / FDD network interoperability processing method and a base station. Background technique [0002] At present, high-speed railways are developing rapidly, and high-speed railways have become an important means of transportation for people's daily travel. Due to the characteristics of high-speed railways, such as fast speed, significant Doppler effect, and concentrated users, the network quality of high-speed railway private network users is also affected by many factors. , among them, the TDD / FDD network interoperability problem of the high-speed rail private network, as one of the factors affecting the network quality, has attracted more and more attention. [0003] At present, the network characteristics of different frequency bands of the high-speed rail private network are obvious. For example, the time division duplex (Time Division Dup...

Problems solved by technology

Under the existing technical conditions, the interoperability strategy between TDD and FDD mainly uses the load balancing function based on the number of users or the switching strategy based on coverage to perform interoperability between TDD / FDD, which cannot fully utilize the respective network advantages of TDD / FDD , cannot effectively improve the network quality of high-speed rail private network user terminals
