A wireless backhaul method, including: a wireless backhaul device generates a first F1AP message, maps the first F1AP message to a signaling-plane bearer of an LTE Uu interface, and sends the first F1AP message to a primary base station of the wireless backhaul device via the signaling-plane bearer of the LTE Uu interface. The primary base station obtains the first F1AP message via the signaling-plane bearer of the LTE Uu interface, encapsulates the first F1AP message into a first X2AP message, and sends the first X2AP message to a secondary base station of the wireless backhaul device. The secondary base station receives the first X2AP message and obtains the first F1AP message based on the first X2AP message.

A computer implemented method for controlling call capacity in a mobile network. The method includes: activating a mass event mode in a first cell of a first base station, wherein the first cell is a high frequency band cell, and wherein operating in the mass event mode comprises: checking if any low frequency band cells are available in a first sector served by the first cell; and responsive to detecting that one or more low frequency band cells are available, switching, at least some, voice call connections of the users of the first cell to at least some of the available low frequency band cells.

A computer-implemented method includes creating an awareness module on a first near-Real-Time RAN Intelligent Controller (near-RT RIC) that controls a first domain. The first near-RT RIC identifies a second near-RT RIC that controls a second domain, which has a mutual impact on the first domain. The first near-RT RIC creates a first border state that represents attributes of the first near-RT RIC and the xApps of the first near-RT RIC. The first near-RT RIC receives from the second near-RT RIC, a second border state of the second near-RT RIC. The first near-RT RI generates, a policy for the first near-RT RIC and the second near-RT RIC by analyzing the first and second border states. The first near-RT RIC updates a parameter only if the policy allows a requesting xApp to update the parameter.

The art relates to a communication method and device for a wireless communication network and a wireless communication network. In the communication method, to one cell cluster in at least one cell cluster included in the wireless communication network, an Uplink-downlink ratio configuration scheme of the cell cluster during the next ratio configuration adjusting period is determined based on un-allocatable prediction amount for un-allocatable services of each cell in the cell cluster, and allocatable prediction amount for the services, which can be allocated to other cell(s), of each cell in the cell cluster, thus utilization efficiency of communication resource is optimized, and the cells in the cell cluster have the same communication frequency and Uplink-downlink ratio configuration scheme. According to the embodiments of the invention, the utilization efficiency of communication resource can be improved.

This application discloses an information transmission method in a communication system. According to the method, a master base station sends a request message to a secondary base station for requesting to transfer one or more flows from the master base station to the secondary base station for transmission to a terminal device. The request message carries one or both of identification information of each flow, and information of a data radio bearer (DRB) associated with each flow. The master base station receives a response message from the secondary base station, indicating whether each of the one or more flows is admitted or rejected by the secondary base station. Based on the identification information of the flows, DRBs are mapped to the flows. QoS management of information transmission is more refined, and requirements of 5G communication systems for QoS management of information transmission in a dual connectivity scenario can be met.
