Technically speaking, IMSI can completely solve the international roaming problem. However, since North America still has a large number of amps

Control Protocol (BICC). The signaling interconnection of the server and the external traditional network uses signaling gateways (SGW) to achieve interconnection and interoperability. Among them, T-SGW realizes the interconnection and interworking with the public Switched Telephone Network (PSTN) network, R-SWG realizes the interconnection and interworking with 2G mobile network.The R4 network structure is directly evolved from R99, and some network elements (such as MGW, T-SGW, R-SGW) are add

In the Microsoft operating system, there are two places that can be used to store users ' private files by default. One is the very familiar "My Documents". Because My documents are saved in a user profile, if the roaming user Profile management policy is used, managing the user's private files through My Documents can affect the performance of the operating system. Because if a user uses a roaming user pro

Wireless switches are currently one of the most common types of switches. Here we mainly explain the management functions and security of wireless switches. The most prominent feature of a wireless switch is its management performance, which is also one of the most basic functions of a wireless switch. It is a good supplement for Wireless AP. Under the centralized control of a wireless switch, a Wireless AP can reduce its management, security, QoS, and other functions. Of course, before becoming

A wireless switch has many advantages. In many enterprise-level networks, there are many wireless switches, and its prominent advantage is the ability to manage. For a complex layered network, a switch is a wise man, let's take a closer look at the advantages of this network manager and wireless switch. Of course, before becoming a "thin" AP, you must polish your eyes and carefully select "Weight Loss" products. Otherwise, the expected results may fail, and the money will be wasted. When purchas

to multiple BSSID Basic Service Set Identifiers). The virtual AP can provide comprehensive control over broadcast traffic. It is very important to control the broadcast traffic, including network-level messages, because it has a potential negative impact on performance. Intelligent Control over broadcast forwarding through proxy ARP and other mechanisms ensures that only the target recipient receives broadcast traffic. The decrease in traffic maximizes the bandwidth and network throughput. Beca

communication field, various wireless access technologies will coexist, and various mobile communication systems will be mutually compatible and cooperative. 2. hybrid networking of TD-SCDMA and WiMAX The third generation mobile communication technology mainly includes WCDMA, CDMA 2000, TD-SCDMA and so on, with voice communication, although it can maintain communication at high speed mobile, but the highest data transmission rate is only 2 Mbit/s, it cannot meet the requirements of mobile citie

I. concept explanation: Fat AP (Fat AP): Fat AP can be used independently. Currently, some Fat AP can be converted to thin AP by upgrading IOS (by upgrading IOS to thin AP ). Features of Fat AP: Fat AP is relative to Fit AP, fat AP integrates the features of the physical layer, user data encryption and authentication, QoS, network management, roaming technology, and other application layers of WLAN. The Fat AP wireless network solution can be composed

between a fixed terminal and a mobile terminal is the portability and mobility of the terminal. Mobile terminals are mostly private and carried by individuals. They are highly mobile and need to support roaming and switching between networks and networks. The roaming range is large and can be global. Fixed Network terminals are generally deployed in a fixed place, such as a home or office. They share some

development needs as much as possible, which often leads to a large number of Preset low-utilization information points. Once the development of the network exceeds the design plan, the network transformation will be performed at a high cost. However, WLAN can avoid or reduce the above situations. Easy to expand WLAN has multiple configuration methods, and can be flexibly selected as needed. In this way, WLAN can be used for a small network with only a few users to a large network with thousand
