[0051] figure 1 It is an interaction diagram of a method for reporting a cell's ability to support downlink high-order modulation according to the first embodiment of the present invention. Such as figure 1 As shown, there is provided a method for the drift wireless network to report the downlink high-order modulation support capability of the cell under its jurisdiction through the process of successfully establishing or adding a link. The method includes the following steps:

[0052] Step S110, the serving radio network controller sends a radio link establishment request or a radio link addition request message to the drift radio network controller; and

[0053] Step S120, when the drift radio network controller has successfully established or added all the links that need to be established or added, the drift radio network controller sends a radio link establishment response or a radio link addition response message to the serving radio network controller, The radio link...

[0055] figure 2 It is an interactive diagram of a method for reporting a cell's ability to support downlink high-order modulation according to the second embodiment of the present invention. Such as figure 2 As shown, there is provided a method for the wireless network to report the downlink high-order modulation support capability of the cell under its jurisdiction through the process of unsuccessfully establishing or adding a link. The method includes the following steps:

[0056] Step S210, the serving radio network controller sends a radio link establishment request or a radio link addition request message to the drift radio network controller; and

[0057] Step S220: When the drift radio network controller partially successfully establishes or adds a link that needs to be established or added, the drift radio network controller sends a radio link establishment failure or radio link addition failure message to the serving radio network controller. The link establishme...

Abstract

The invention provides a method and a device to report the small area support ability to a downward advanced modulation. The method and the device are used to report whether the relative small area supports the downward advanced modulation by a shift wireless network controller, wherein, the method comprises the following steps that: after the shift wireless network controller receives request information from a service wireless network controller, the shift wireless network controller reports the information of the small area support ability to the downward advanced modulation to the servicewireless network controller through an information order, therefore, through the invention, the service wireless network controller is caused to be able to gain the information to take part in the decision on whether the downward advanced modulation method is used to a user apparatus.

Description

technical field [0001] The present invention relates to a wireless communication system, and more specifically, to a method and device for reporting a cell's ability to support downlink high-order modulation, which is used for a drift radio network controller to report whether a related cell under its jurisdiction supports downlink high-order modulation. Background technique [0002] The access network includes one or more radio network subsystems. Each radio network subsystem is a subnet in the access network, which includes a radio network controller and one or more node Bs. The radio network controller is the network element responsible for controlling the radio resources of the access network. The main function of Node B is to process the physical layer of the air interface, and also perform some basic radio resource management operations. [0003] When a user equipment establishes a communication relationship with multiple radio network controllers, if different radio...
