Method for processing in-device coexistence configuration information, apparatus and system
View Patent ↗A method for processing in-device coexistence configuration information, apparatus and system. The method includes: notifying, by a source base station to a target base station, first in-device coexistence configuration information configured by the source base station for terminal equipment, when handover from the source base station to the target base station occurs in the terminal equipment. In this way, the source base station may notify the first in-device coexistence configuration information configured by it for the terminal equipment to the target base station; the target base station receives the first in-device coexistence configuration information, determines whether to configure the terminal equipment with in-device coexistence configuration information, and then notifies the source base station of related configuration information via a handover command. Wherein, when handover occurs in the terminal equipment, the in-device coexistence configuration information may be processed effectively.
1. A method for processing in-device coexistence configuration information during a radio resource control (RRC) connection reestablishment procedure, comprising:
releasing, by terminal equipment, in-device coexistence configuration information configured by a serving base station for the terminal equipment, when the terminal equipment initiates RRC connection reestablishment, the in-device coexistence configuration information indicating whether the serving base station permits the terminal equipment to transmit in-device coexistence indication to the serving base station and the configuration information to control the terminal equipment to perform autonomous denial of uplink signal transmission of an LTE system; and
not transmitting in-device coexistence indication by the terminal equipment to a new base station, when connection between the terminal equipment and the new base station is reestablished and the terminal equipment does not receive in-device coexistence configuration information containing first configuration information transmitted by the new base station, wherein the first configuration information refers to configuration information configured by the new base station to indicate a permission to transmit in-device coexistence indication to the new base station by the terminal equipment.
