A joint channel correction method, an apparatus, and a system are disclosed. The joint channel correction method includes: sending a first joint channel correction instruction to a first RRU; sending a second joint channel correction instruction to a second RRU; receiving a result sent by the second RRU about reception of the first correction reference signal through X2 receive channels in X2 traffic channels; receiving a result sent by the first RRU about reception of the second correction reference signal through X1 receive channels in X1 traffic channels; and obtaining correction compensation coefficients of the X1 traffic channels and/or the X2 traffic channels through calculation. Technical solutions provided by embodiments of the present application help implement channel correction between RRUs without a channel self-correction function.

Joint channel correction method, related apparatus, and system

A method for establishing a virtual base station includes: receiving a message of poor network coverage sent by an operator server, where the message includes information of a location where network coverage is poor and information of a second mode; acquiring, according to the information of the location and the information of the second mode, a multimode terminal capable of being compatible with the second mode; returning an identification of the multimode terminal to the operator server; receiving a virtual base station establishment request message sent by the operator server; forwarding, according to the identification of the multimode terminal, the virtual base station establishment request message to the multimode terminal; and forwarding a virtual base station successfully-established message to the operator server.

Method, device, and system for establishing virtual base station and transferring data

Embodiments of the present invention disclose a method and an apparatus for creating a virtual base station. The creating method includes: receiving a virtual base station creation request sent by a third-party server; sending a virtual machine creation request to an RAN; receiving a virtual machine creation complete response sent by the RAN; sending a base station image load request to the RAN; receiving a base station image load complete response sent by the RAN; sending a virtual base station creation complete response to the third-party server, where the virtual base station creation complete response includes a virtual base station ID. The present invention can realize creation of a virtual base station.

Method and apparatus for creating virtual base station

A method for generating a wireless virtual network and a wireless network control device are provided. In some feasible embodiments of the present invention, a wireless network control device responds to a wireless virtual network establishment/modification request of a wireless virtual network demander, and configures a base station according to the wireless virtual network establishment/modification request. The wireless network control device receives configuration completion response of the base station, confirms the success of wireless virtual network establishment/modification, and sends a parameter of the wireless virtual network to the wireless virtual network demander. Then, the wireless network control device receives a parameter confirmation message of the wireless virtual network demander, and the wireless virtual network takes effect.

Method for generating wireless virtual network and wireless network control device

A method, system and apparatus for providing access mode selection to multimode terminal are disclosed. After selecting an access mode according to a certain policy, a routing decision entity correspondingly instructs a routing execution entity to perform a call connection in the selected access mode. The method for providing access mode selection to multimode terminal includes the following steps: (1) when establishing a registration connection, a terminal notifies related information of a current access network type to a network side; and (2) when performing a call connection to a called party, a routing decision entity on the network side selects the access mode and correspondingly instructs a routing execution entity to perform the call connection according to the related information and the selected access mode.
