Base station subsystem (BSS) Base station subsystem is connected to the Mobile Service Switching Center (MSC) in the Network Path System (NSS) to achieve communication connections between mobile users or between mobile users and fixed network users, and to transmit system signals and user information. Of course, the BSS section should be operated and maintained, and the communication connection betwee

Therefore, it is significant for operators to reduce the cost per bit in order to better meet the needs of users under the premise of guaranteeing service quality. WiMAX is one of the most promising applications. (Computer science) The future of the network will have the following characteristics: IP, broadband, cost more economic, network more convenient management, and a variety of technologies through a unified core network of mut

about this technology, including manufacturers, telecom operators, analysis institutions and other experts. "Wi-Fi is the most successful wireless technology invented by humans ." Huang Xiaoqing, president of the China Mobile Research Institute, said that the frequency of user use of Wi-Fi is 10 times that of mobile communication, and this proportion continues to expand. Li tingwei, president and vice president of global sales of Broadcom Greater China, said in an interview that in the LTE era,

In recent years, the demand for mobility has attracted more and more attention. Mobility refers to the ability to move or roam. Wireless LAN (WLAN) devices can provide unrestricted mobility. WLAN uses wireless communication technology to establish a network within a certain range. It is a product of the combination of

applications. Military communication systems need to be self-organized and mobile. In war, communication systems are vulnerable to attacks from the enemy. ThereforeThe communication system can defend against certain attacks. If a centralized communication system is used, once the communication center is damaged, the entire system will be paralyzed. A distributed system can ensure that some communication nodes or links are disconnected.The remaining parts can continue to work. In the war, it is

At present, GPRS's core network is to introduce two new network nodes in GSM network structure, they are GPRS Gateway support node GGSN (Gateway GPRS supporting node) and GPRS service support nodes SGSN (service GPRS Supporting Node), there is also a need to increase the Group control Unit (PCU) at the machine station side (Packet). GPRS system adopts the Protocol of Special development, which

Fortunately, the machine is equipped with two USB ports. Of course, it should be split into one for the WIFI wireless network card, this makes it easier for the school to use it!I have a NetCore branch NW336 wire

Smart wireless switches are still quite common. Here we will introduce a full-featured smart wireless switch for Small and Medium-sized Enterprises launched by NETGEAR. Here we will share with you, hoping it will be useful to you. Recently, NETGEAR, a global growing commercial network expert and wireless network pioneer, announced at the InteropLasVegas2007 conference that it would be the first full-featured wireless controller designed to meet the wireless infrastructure needs of growing small

On the street, you can watch the news online during a nap in the coffee house, or chat with friends from other places. Once at the airport, the station waited for a long time, and now it can also be used to access the Internet to handle important work or use online entertainment, games, and so on. Similar freedom brought about by wireless Internet access can be said to be numerous, whic

It also integrates content such as mobility, security, and service quality. Therefore, IPv6 Protocol [2] is urgently needed on the mobile Internet. Ii.

A secure and reliable network is the key to the success of enterprise business. The boundaries between the internal and external networks of enterprises are becoming increasingly vague, and the mobility of users is getting stronger and stronger. In the past, we thought that the secur

Wired networks have always been a frequent network type for home and enterprise users. However, with the popularity of wireless networks, wired networks gradually expose their inevitable drawbacks: a large number of cabling and line change projects; lines are prone to damage; nodes in the network cannot be moved. In particular, when connecting distant nodes, it is difficult, expensive, and time-consuming to build dedicated communication lines, serious bottlenecks have been formed for rapidly exp

NGMN also faces a variety of network interconnection and convergence issues. Figure 1 shows the system architecture of NGMN in the future and the coexistence mode between NGMN and the current mobile network, such as 2G/3G circuit domain (CS. Over time, the traditional CS part will be gradually eliminated. In t

IPv6 standards are more conducive to carrying out a variety of services than IPv4 in terms of address space, security, and mobility. Therefore, IPv6 has the advantage of carrying out services from a certain perspective. From the perspective of business development, due to the limitations of IPv4, there is a certain problem in carrying out IPv4-based end-to-end services. Taking the development of P2P as an example, we can clearly compare the advantages

situation is called "Roaming ". The roaming function requires reasonable overlap between cells so that the user will not interrupt the link connection in communication. The access points also need to be coordinated so that users can transparently roam from one community to another. When roaming occurs, you must perform the switchover operation. The switchover can be controlled by the Exchange Board in a centralized manner, or by moving nodes and moni
