Network is built a station morning, wide coverage, even remote districts and rural area have also covered, signal is more more stable than 3G/4G network.If institute
Some communication is merely by public network, it is necessary to produce higher communication cost.In the case of emergency disaster relief, mainly or private network is relied on
Communication.
Private network communication equipment is easy to carry about with one, networking is convenient, user distinguishes priority, can individual calling or group exhale and be easy to team to coordinate
Work, flexibility height, strong security, are widely used in the case of emergency disaster relief.But because of single base station limited coverage area, if
Required coverage is very big, then needs to dispose high-power base station to cover all working ranges.Even if coverage
Very little, it is also possible to run into the limitation on geographical environment, such as mountain range, mountain valley, tunnel or heavy construction etc., it is still necessary to multiple Gao Gong
The base station of rate covers whole communication range.
Interconnecting between current multiple base stations is mainly realized by two ways:The first is realized by IP network
Interconnection, but on mountain, in tunnel or other complex environments, often do not possess the condition of connection IP network;Be for second relaying and
Communication terminal is linked together by the way of " back-to-back ", as shown in figure 1, base station A is connected with a private network communication terminal A2
Together, by communication terminal A2 realize with pass through IP network interconnect base station B, C, D, E coverage in communication terminal it
