Embodiment Construction
[0024] 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.
[0025] In the embodiment of the present invention, the network structure and communication equipment used for the communication coverage along the traffic trunk line refer to the existing technology, and the RRU adopts the multi-carrier RRU; wherein, the multi-carrier RRU adds the multi-carrier characteristic on the basis of the distributed characteristic , The integration of multi-carrier carrier frequency modules has been greatly improved. A single module supports 1 to 6 carriers. Multiple carrier frequency signals of the same RRU are directly combined through digital intermediate frequency, and the same power amplifier module is used to amplify multiple carriers at the same time; large station type There is no need for an external combiner, which avoid...

The invention provides a method of conducting network coverage along traffic tracks and a management device thereof. A network comprises multiple distributed cells, and the distributed cells are distributed along the traffic tracks in a linear mode; each distributed quarter comprises a baseband processing unit and multiple radio frequency processing units, wherein the method includes the following steps of detecting that at least one radio frequency processing unit fails and becomes a broken station radio frequency processing unit; confirming a distributed quarter of the broken station radio frequency processing unit as a broken station quarter; finding at least one adjacent radio frequency processing unit adjacent to a position of the broken station radio frequency processing unit; and increasing transmitting power of the adjacent radio frequency processing unit. The transmitting power of the adjacent radio frequency processing unit is increased so as to further effectively cover a region which is formerly covered by the broken station radio frequency processing unit, and improves communication network quality.
Description
technical field [0001] The invention relates to communication network coverage technology, in particular to a method and management device for network coverage along traffic lines. Background technique [0002] The technology of constructing a private network along the main traffic line for communication coverage is generally applied along the high-speed railway. With the construction of the high-speed railway and the continuous increase of the speed of the original railway train, the existing GSM network cannot guarantee high-speed Coverage performance of trains. During high-speed travel, due to fast fading, Doppler effect, train material on wireless signal attenuation, and the impact of no main coverage area, mobile phone users in the train are often prone to handover confusion, inability to connect, and dropped calls. [0003] The existing solution is to use distributed cells to cover the network along the railway, such as figure 1 As shown, each set of distributed cell...
