The composition of GPRS network

GPRS network is based on the existing GSM network to achieve. In the existing GSM network need to add some nodes, such as GGSN (Gateway GPRS supporting NODE,GPRS Gateway support node) and SGSN (serving Gsn,gprs Service support node). GSN is the most important network node in GPRS network. GSN has a mobile routing management function, it can connect various type

GPRS learning-sgsn, ggsn, PCU

To implement GPRS services, three new logical network entities need to be introduced in the existing GSM network: Service GPRS Support Node (sgsn) and Gateway GPRS Support Node (ggsn) and Group Control Unit (PCU)Sgsn: Service GPRS Supporting NodeGgsn: Gateway GPRS Supporting NodePCU: Packet Control UnitGSN (GPRS Supporting Node) is the GPRS Support contact, which is the mostImportant. GSN has the mobile Routing Management function. It can connect to v

"Three knives" cut off the hidden danger--Ruijie Campus network scheme

With the deepening of information process, network security has become a common challenge for the people in the information age, and it can be interpreted from two different angles, that is, information security and control security. To make the network security truly "watertight", in addition to make the network security, credibility and more to achieve controllable, can be managed. In order to create "high-speed, stable, controllable, can be managed" the Health network environment, the major

Application of GPRS technology in power distribution monitoring system [reprinted]

transmission can use GPRS, the application of mobile phones is upgraded to a higher level. The development of GPRS technology is also very "economic", because it only needs to follow the existing GSM network to develop. GPRS is widely used, including sending and receiving emails through mobile phones and browsing the Internet. The biggest advantage of GPRS is that its data transmission speed is not comparable to that of WAP. Currently, the transmission speed of the GSM mobile communication netw

in probing into the reasons for the failure of various precautions against DDoS attacks, the unpredictable source of attacks and the endless array of attacking methods. In order to completely break this passive situation, the current industry-leading network security technology manufacturers have tended to agree: that is, in the network configuration of the overall linkage of the security system, through the software and hardware technology, in-depth network terminals of the global preventive m

X.25 packets, to be passed through in a tunnel between GSN components. Because each user can only have one pipe at a time, the TID used to differentiate between different GTP must be distinguished from the IMSI of different users and the NSAPI distinguishing between different applications. In the existing IP network through VPN to build GPRS backbone network can ensure that the IP message from outside the network is not in the backbone of the route,

data, enabling it to be securely routed through an external IP network. The GP interface is defined in 3gppts23.060, which is actually the same as the GN interface. The only difference in the standard is that the GP interface is used to communicate between the plmn of the GSN. GP contains all GTP signaling information that supports GN, but the path management capabilities of the GN interface are not used to monitor the availability of all SGSN in th

the switch increases sharply after a large number of abnormal ARP packets flood, causing management difficulties, anti-virus and firewall cannot be deployed at the boundary. When the number of events reported by IDS reaches astronomical numbers, they cannot be processed. network administrators keep a bunch of security systems and devices, however, you can only perform manual search repeatedly ".

process, there are s-cdr and g-cdr at the same time, and because the data communication duration is long and the inclusions are complex, the last session of the GPRS Business node (GSN) produces multiple partial records (Partial record), Multiple records that describe a PDP context require an identifier to indicate that they belong to a single session, which is the C-id. C-id is determined in the process of establishing a PDP context between SGSN and

It is a public address code that can be queried manually or automatically. Based on bd_addr, various confidentiality and security codes can be obtained using

GPRS access network leads to wireless IP

MSISDN numbers used in GSM, the mobile phone MS identity also needs to be assigned an IP address. The identification of SGSN and GGSN of the Network Element equipment includes both the signaling address and the IP address of the Data GGSN. The IP address is used for communication between GSNSGSN and GGSN, GSN communicates with MSC, HLR, and other entities using the 7th signaling address. There are two important database records in the GPRS system. On

First, establish a GPRS route between the data network and GGSN through the standard protocol of the data network. The data unit sent by the data network user, such as the PDU in PSPDN). The data unit PDU is sent to the GGSN through the established GPRS route. The GGSN then sends the pdu to the sgsn where the mobile station is located. The GSN encapsul
