sgsn 中文意思是什麼

sgsn 解釋
支持點
  1. Sgsn 900 1800mhz tdma digital cellular mobile communication network test method of gprs general packet radio service base station system and serving gprs support node interface

    900 1800mhz tdma數字蜂窩移動通信網通用分組無線業務gprs基站子系統與服務gprs支持節點
  2. When there is a backbone ip network in the province, the gsn, a generic term for both the sgsn and the ggsn, can serve as an access node to the backbone ip network

    當省內有ip骨幹網路時， gsn （ gprs服務節點與關口節點的統稱）節點作為ip骨幹網的接入節點。
  3. The rnc, the wireless part of the 3g network is connected to the msc via interface iucs and to the sgsn via interface iups. so the gprs network can support the transition of the network easily

    3g網路的無線部分rnc通過iucs介面與msc連接，通過iups介面與sgsn連接，由此可見建設gprs網路后，能夠很容易地支持網路的過渡。
  4. For a small local network, the gsn node can be located in the exchange room. the pcu is connected to the sgsn on a ppp basis so as to save trunks. when there are many pcus and they are located in places other than the exchange, they can access to the sgsn via the existing fr network or a self - built fr network

    對于規模較小的本地網，可將gsn節點設置在交換機房內，其pcu經過交換機以ppp的方式同sgsn連接，可以節省中繼線路。當pcu單元數量多且與交換機位於不同的地方時，可以通過現有的fr網或自己組建fr網路接入到sgsn中，此時gsn節點位置相對靈活。
  5. The use of the fr network can converge data from each pcu to one of the ports of the sgsn, leading to great reduction of ports. now, the pcu and the sgsn both serve as the user end of the fr network

    採用fr網路，可以將各pcu的數據匯聚到sgsn的一個埠上，大大節省了埠數，此時pcu和sgsn同時作為fr網路的用戶端。
  6. Confuguration 1 applies to backward areas, where pcus are added to the bss part and connected to sgsns of other local networks on a pppfr basis, with each sgsn responsible for more than one local network

    方式1應用於一些落後地區的市區。這些地區的bss部分增加pcu單元，通過pppfr等方式連接到其它本地網的sgsn ，一個sgsn負責多個本地網。
  7. The ppp mode does not need fr networks, with the pcu serving as the user end and the sgsn as the network end. each pcu needs a corresponding port on the sgsn side, leading to great consumption of the resources of ports and their low utilization

    採用ppp方式，不需要有fr網路， pcu作為用戶端而sgsn作為網路端，此時每個pcu端在sgsn側需要一個對應的埠，埠資源消耗大且利用率低。
  8. Using fr and atm can solve the problem of additional ports and their low utilization. the sgsn may have more than one pvc as required. though dependent on other networks, this networking plan is flexible. its network structure is shown in figure 5

    採用fr或atm ，就可以解決埠數目和效率等問題， sgsn根據需要可以有多個pvc ，這種組網方式依賴其它的網路但組網方式較為靈活，網路的結構如圖5所示。
