Provided are a CSI feedback signaling instruction configuration method and base station, the method comprising: a base station side notifies a terminal side, via the first high layer signaling of a UE-Specific, a CSI-RS resource for measuring CSI, the CSI-RS resource comprising at least one of: the time frequency position of the CSI-RS resource in a subframe, the aerial port number configuration of the CSI-RS resource, the period of the CSI-RS resource and subframe offset, the sequence identifier of the CSI-RS resource, and the power control information of the CSI-RS resource; the base station side instructs the terminal side to feed back the CSI corresponding to the CSI-RS resource. In the present invention, the base station side flexibly configures the terminal side to feed back various kinds of CSI information, thus enabling the base station side to flexibly and dynamically acquire the CSI, and in turn realizing precise link self-adaption and data transmission, and reducing the uplink feedback overhead and measurement complexity of the terminal side.

The invention provides a web page pre-reading and integration method and a system based on a relay server. The method comprises the following steps of: 110, requesting corresponding web page data for a network resource server according to a web page access request of a mobile terminal; 120, analyzing a pre-read keyword of the web page data returned from the network resource server; 130, acquiring uniform resource locators (URL) of sub web pages from the network resource server from a priority of the pre-read keyword; 140, pre-reading the sub web pages with the specified number of layers from the network resource server according to the URLs of the sub web pages and the priority of the pre-read keyword; 150, merging and rearranging the all acquired sub web pages; and 160, sending a combined web page after mergence and rearrangement to the mobile terminal. By utilizing the method and the system provided by the invention, the effective sub web pages can be acquired flexibly, and the sub web pages are merged and rearranged, so that the web page is shown more flexibly and quickly with humanity and high speed, an operating flow of a user is reduced, and an experience of the user on browsing the multi-sub web page is improved.

The invention relates to a mine communication system, in particular to an emergency communication support system of coal mines. The emergency communication support system comprises an integrated command rescue call center server, an IP (Internet Protocol) telephone switchboard and an voice gateway, which are interactively connected through Ethernet, wherein the voice gateway is simultaneously connected to a dispatching switchboard, an integrated IP voice access gateway for mine is adopted as the voice gateway, a 32-bit embedded microprocessor is adopted for the voice access gateway, a protocol conversion address of the microprocessor is connected with a system interface module, a serial port of the microprocessor is connected with a field bus protocol conversion module, the field bus protocol conversion module is connected with an underground dispatching amplified phone, an MAC (Media Access Control) address of the microprocessor is connected with a network module, and the microprocessor is connected with an Ethernet switchboard through the network module. The microprocessor is provided with a corresponding data interface for connecting an optical fiber transmission module, the microprocessor is accessed to an underground industrial optical fiber ring net through the optical fiber transmission module, and the underground loud-speaking phone is accessed to the underground industrial optical fiber ring net through a converter. According to the mine communication system disclosed by the invention, a difficult problem of the speed bottleneck in the wide-band network underground communication of a mine area is solved, and a way is paved for networking and informatizing of a mine monitoring system.
