Embodiment Construction

[0035] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0036] The information reporting method described in the embodiment of the present invention is applied in a dual connectivity architecture. Both Long Term Evolution (LTE) and 5G base stations are connected to the LTE core network. The LTE eNB always acts as the master eNB (i.e. MeNB), and the 5G gNB acts as the slave eNB (i.e. SeNB). The LTE eNB and 5G gNB are connected to each other through the Xx interface. even. The S1-C on the control plane is terminated at the LTEeNB, and the control plane information between LTE and 5G is exchanged through the Xx-C interface. The user plane has different user plane protocol architectures in different dual connection modes. The data plane radio bearer can be served independently by the MeNB or the SeNB, or can be...

Abstract

The invention provides an information reporting method and device, a terminal and network side equipment. One embodiment of the information reporting method is applied to a terminal, and comprises thestep of reporting MCG abnormal information through a signaling radio bearer SRB 3 if it is detected that a main cell group MCG is abnormal. The embodiment of the invention discloses an information reporting method. When the MCG is abnormal, the terminal reports MCG abnormal information to the SCG side through the SRB3, and performs RRC connection reconfiguration with the network side, thereby avoiding a reestablishment process of RRC connection when the MCG is abnormal in the prior art, and further avoiding transmission interruption of the MCG side and the SCG side caused by the reestablishment process.

Description

technical field [0001] The present invention relates to the field of wireless technology, in particular to an information reporting method, device, terminal and network side equipment. Background technique [0002] In a dual connectivity (Dual Connectivity, DC) architecture, it generally includes a master cell group (Master CellGroup, MCG) and one or more secondary cell groups (Secondary Cell Group, SCG). Currently, the dual connectivity architecture includes the case where one MCG is connected to multiple SCGs. After the security on the MCG side is activated, the Radio Resource Control (RRC) signaling is transmitted through the Signaling Radio Bearer (SRB) 1 or SRB2. transmission. [0003] In the NR system, when MCG abnormality is detected, NR security is activated at this time, and the UE triggers the RRC re-establishment process. The RRC connection re-establishment process is divided into two phases: the preparation phase and the implementation phase. In the preparatio...
