Abstract: A dynamic AP grouping method and a dynamic AP grouping device are provided. It is able to provide services to UE in a UE-centered manner as compared with a traditional mode where the services are provided to the UE in a network-centered manner, thereby to prevent the UE from frequently acquiring a network environment, and provide the data transmission service to the UE at a low speed or in a stationary state through APGs. In addition, during the movement of the UE, it is able to transmit the services to the UE through dynamic refresh of APs in the APGs and coordination of the APs in the APG. It is able to reduce the number of handover operations made by the UE, and perform the handover operation in the APG not through a core network, thereby to reduce signaling load of a core network.

Abstract: Disclosed are an information transmission method and a device thereof. The method comprises: after determining that a UE needs to conduct base station handover, a source base station which supports an eDDA auxiliary information reporting and processing capability querying whether a candidate target base station supports the eDDA auxiliary information reporting and processing capability or not; and if the source base station queries that the candidate target base station supports the eDDA auxiliary information reporting and processing capability or fails to query whether the candidate target base station supports the eDDA auxiliary information reporting and processing capability or not, or when the source base station does not query whether the candidate target base station supports the eDDA auxiliary information reporting and processing capability or not, the source base station sending to the candidate target base station the eDDA auxiliary information about the UE, to enable the candidate target base station which supports the eDDA auxiliary information reporting and processing capability to conduct radio resource parameter configuration on the UE based on the received eDDA auxiliary information about the UE. By using the embodiments of the present invention, during the process of handover a UE from a source base station to a target base station, the efficiency for the target base station which supports an eDDA auxiliary information reporting and processing capability to acquire eDDA auxiliary information about the UE is improved, and the air interface signalling overhead is reduced.

Abstract: The embodiments of this application relate to the field of wireless communications. Disclosed are an auxiliary information reporting and information sending method and device, so that a target base station can acquire the latest auxiliary information of a user equipment (UE) and then can provide the most reasonable configuration for the UE. In this application, the UE reports the auxiliary information to a source base station, and determines whether it is required to re-report the auxiliary information in a target cell; if determining that it is required to re-report the auxiliary information in the target cell, the user equipment reports the auxiliary information to the target base station after being switched to the target cell. It can be seen that, in this solution, the target base station can acquire the latest auxiliary information of the UE, so as to provide the most reasonable configuration for the UE.

Abstract: The present invention discloses a method and device for judging Radio Link Failure (RLF) in Carrier Aggregation (CA) technology, which are used to effectively judge whether a radio link is failed or not in CA technology. Said method comprises: on an evaluation point, comparing the determined radio link quality parameter of each carrier participating in the RLF judgement with the corresponding radio link quality parameter threshold, determining whether to trigger an in-sync indication or out-of-sync indication on the evaluation point, and judging whether the radio link of the User Equipment (UE) is failed according to the number of the continuously received in-sync indications or out-of-sync indications. The embodiment of the present invention determines whether to trigger an in-sync indication or out-of-sync indication by comparing the radio link quality parameters of the carriers participating in the RLF judgement with the corresponding radio link quality parameter thresholds, and thereby judges that whether the radio link is failed or not in CA technology.

Abstract: A method for processing information and a device for processing information are provided. The method for processing information is applied to a first node. The method includes: receiving, by the first node, an indication message from a network side, wherein the indication message indicates a user equipment under the first node to hand over to a second node; and negotiating, by the first node, with the second node to reserve radio link layer control protocol (RLC) status information and cached data of all bearers of the user equipment, so that the second node provides a continuing data service to the user equipment based on the reserved information.

Abstract: A wireless network access control method is provided. After an RRC connection is established between a first base station and a UE, a radio bearer for the UE is established in accordance with a service request from the UE. When determining that the UE meets a requirement on communication with second base stations whose types are different from the first base station, a dedicated configuration resource is allocated for the UE for enabling the UE to initiate a dedicated uplink detection signal. Dedicated second base stations are instructed to measure the dedicated uplink detection signal initiated by the UE, and one of the dedicated second base stations is allocated for the UE in accordance with measurement results. The UE is instructed to perform data transmission through the second base station allocated for the UE.
