Description

1273804 is different. The uranium PHS base station is located in office buildings, communities, and goods companies for regional signal coverage. With extremely sophisticated terminals, instant calls can be used in the base station coverage. In addition, PHS also provides low-transmitt power, high-quality, high endurance, low-cost and multi-selective communication methods. It is very easy to connect wired or wireless types of public telephones and mobile communication networks through PHS personal mobile phone systems, in addition to mobile phones and communications. The price is also much lower than that of the mobile phone manufacturers.

PHS-related common air interfaee (C: AI J is developed by Sakamoto's wireless system R&D center, and also includes wireless intercom between two mobile phones. CAI includes three aspects, one is wireless interface It mainly specifies the detailed standard of the data modulation carrier frequency or its working mode. The second is the three-layer 仏5 tiger. The second is the speech coding and transmission plan. The working frequency band of PHS is 1895~1918·1 MHz, with specific control. Channels, 4 channels of lower frequency are used as environments for residential or office environments, and 37 channels are designated for public communication applications. PHS uses the public network such as PSTN or ISDN as the backbone of the system connection. ISDN is connected, and the PHS voice channel transmission rate can reach 32Kbit/s.

As shown in the first figure, for the PHS stand-alone network architecture, phs provides 64kbps and 32kbps mobile data Internet services, making the Internet no longer limited to home or specific locations. The core of the PHS mobile data Internet service is PDX (P-mail Deluxe) Center. When PHS users want to use the mobile data service, they must exchange data with the remote content provider (c〇ntent Provider) through PDX Center. The remote content provider needs to develop the network content according to the PDX format. Since the PDX format is similar to e-mail, the user must go through the operator's PDX when browsing the Internet.

Center, use the way of mail to and from the PDX Center, ρ]) χ 1273804

Center then sends the user's mail to HTTP format and sends it to CP Sever.

MiMi (Mobile Information Mobile Internet) is a value-added service provided by Volkswagen Telecom. The service items include "Thumb Mail" and "Thumbs Intelligence". "Thumb Mail" provides various functions of mobile phone to send and receive emails. Provide a wealth of information and entertainment content, allowing users to use the mobile phone to access the information or online entertainment activities. GPRS (General Packet Radio Service) by the European Electric Standards Association (European)

Developed by Telecommunication Standard Institute, GPRS is used to improve GSM (Global Systems for Mobile)

Communications; Global Communications System) The problem of slow data transmission on mobile data transmission services has increased the transmission speed of the original 9.6 kbps to 64 kbps. GPRS is delivered as a "packet switch", allowing users to more efficiently access important information on wired or wireless networks through mobile handsets, enabling mobile digital communications technology to take it to the next level. GPRS is more efficient and accurate than the original "circuit switch" GSM in terms of transmission speed. In addition to transmitting universal plain text messages, GPRS mobile phones can simultaneously transmit integrated plain text and any pictures. , multimedia, music, text and even multimedia messages in video and video, greatly enhance the applicability and scalability of mobile data transmission. Please refer to the second figure. For the GPRS network architecture, the GPRS network is built on the existing GSM mobile communication network architecture. The gprs network is not required to be replaced with the existing GSM network equipment. 1273804 is a new network device node for SGSN (Serving GPRS Support Node) and GGSN (Gateway GPRS Support Node) to handle packet transmission and transmission and reception functions. In addition, it is necessary to upgrade the software function in the appropriate device to form a GPRS network. The original GSM network equipment can still be used. BTS (Base Transceiver Station) refers to the §fl number used to receive the user's transmission of §fL information. When the user sends a message through the mobile phone, it will first connect with the BTS (Base Transceiver Station) and then send the message. Transfer to the receiving end. BSC (Base Station Center) and BTS can form a GSM network service area, users can use GSM network communication within the scope of service, and BSC can connect with multiple BTS at the same time. After the software is modified and upgraded, it can process the logical packet data and flexibly use the GPRS mobile phone function to communicate. The MSC (Mobile Services Switching Center) can control multiple BSCs at a time, and convert the message signals to another MSC or PSIN (Public Switching Telephone Network) to provide inter-network exchange. Function to successfully complete the establishment of the connection. The GPRS service support node is called SGSN (Serving GPRS S叩port Node). When the mobile phone uses the GPRS network, it will establish a connection with the SGSN. When moving between different cells, it can be switched without changing the logical connection. . The SGSN is responsible for recording which users are within the scope of the service, identifying the legitimate users of the GpRS, recording the BTS of the user, and the Dynamic lp Address of the user equipment. After receiving the data from the GGSN, the SGSN is packaged and packaged. If the user transmits the information belonging to the packet, According to the judgment of the BSC, the poor material of the packet is transmitted to the SGSN, and the exchange and transmission of the packet are performed by the SGSN. 1273804 GPRS support section, system a n,
