Problems solved by technology

However, when the quality of the uplink VOLTE call is poor, the power of the terminal is limited, and the maximum power cannot be transmitted on the voice carrier, which will cause VOLTE perception loss in the uplink weak coverage and high interference areas.

Embodiment 1

[0035] figure 1 A flow chart showing a carrier configuration method based on 5G NSA voice calls of the present invention, as shown in figure 1 As shown, the method is applicable to the base station and includes the following steps:

[0036] S101: Receive a transmit power headroom reported by a user terminal during a VOLTE call.

[0037] In this step, the base station may receive the transmit power headroom reported by the user terminal during the VOLTE call in real time or periodically. The transmit power headroom is obtained through the power headroom report (PHR) information. The PHR information carries the power headroom report of the maximum transmit power of each CC in the aggregated carrier group. Referring to the protocol, the PHR is mainly used for calculation The user terminal periodically reports the difference between the estimated uplink transmission power and the maximum transmission power of the user terminal UE to the base station, so as to adjust the transmis...

[0058] image 3 shows a structural block diagram of a base station and a user terminal provided by an embodiment of the present invention, as shown in image 3 As shown, the carrier configuration device 310 based on 5G NSA voice calls is suitable for base stations, and the carrier configuration device 320 based on 5G NSA voice calls is suitable for user terminals. The carrier configuration device 310 based on 5G NSA voice calls includes: a first receiving module 301, Judgment module 302 and configuration module 303 . The carrier configuration device 320 based on 5G NSA voice call includes: a reporting module 304 , a second receiving module 305 and a processing module 306 .

[0059] Wherein, the first receiving module 301 is configured to receive the transmit power headroom reported by the user terminal during the VOLTE call.

[0060] Wherein, the transmission power headroom refers to the difference between the uplink estimated transmission power and the maximum transmission ...

Embodiment 3

[0071] An embodiment of the present invention provides a non-volatile computer storage medium, the computer storage medium stores at least one executable instruction, and the computer executable instruction can execute a 5G NSA based on the base station in any of the above method embodiments Carrier configuration method for voice calls.

[0072] Specifically, the executable instruction can be used to make the processor perform the following operations:

[0073] Receive the transmit power headroom reported by the user terminal during the VOLTE call;

[0074] Judging whether the transmission power headroom reported by the user terminal meets the connection reconfiguration condition;

[0075] If yes, generate a connection reconfiguration message, and send the connection reconfiguration message to the user terminal, so that the user terminal deletes the 5G auxiliary carrier according to the connection reconfiguration message, and occupies the 4G voice service carrier for VOLTE ca...

Abstract

The invention discloses a carrier configuration method and device based on a 5G NSA voice call, and the method comprises the steps: receiving a transmitting power margin reported by a user terminal in a VOLTE call process through a base station in the VOLTE call process; judging whether the transmitting power headroom reported by the user terminal meets a connection reconfiguration condition or not; if yes, generating a connection reconfiguration message, and sending the connection reconfiguration message to the user terminal, so that the user terminal deletes a 5G auxiliary carrier according to the connection reconfiguration message, and only occupies a 4G voice service carrier to perform a VOLTE call, thereby realizing the purpose that in a poor-quality scene such as uplink interference or uplink weak coverage, the carrier transmitting power of the user terminal can be concentrated on the 4G voice service carrier, so the VOLTE voice call service transmitting power is maximized, the voice call service perception is guaranteed, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a carrier configuration method and device based on 5G NSA voice calls. Background technique [0002] 5G has two networking methods, one is non-standalone networking (Non-Standalone, NSA), and the other is independent networking (Standalone, SA). Non-independent networking (NSA) refers to the use of existing 4G infrastructure to deploy 5G networks. The 5G carrier based on the NSA architecture only carries user data, and its control signaling is still transmitted through the 4G network. Carrier aggregation (CarrierAggregation, CA) is a transmission bandwidth technology used in 5G communications. Carrier aggregation is a technology that aggregates at least two component carriers (Component Carrier, CC) to achieve greater transmission bandwidth. When the user terminal (UserEquipment, UE) transmits data to the base station, it calculates the actual total transmission p...
