Taking account of the context of China, this paper proposes a new tripartite dynamic game model, of which the government agencies are regarded as the third body. Later, it presents a...
Focusing on the requirement the validity of standby route under high speed movement scene of wireless sensor network, an optimized AOMDV routing protocol based on self-adaptive node speed (ANS-AOMDV) is proposed. In ANS-AOMDV, the update rule based on self-adaptive node speed is also adopted for standby route in order to solve the standby route invalidation problem existing in route update method...
SIP (Session Initial Protocol) is attacked easily by DoS flooding thanks to it's open, the queue scheduling scheme can alleviate the SIP server's influence caused by DoS flooding attack at a certain extent. By analyzing SIP message character and existing queue scheduling scheme, we propose a INVITE DoS flooding attack defense mechanism based on CWFQ (Custom Weighted Fair Queue) and simulates it's...
IT support system is important to the telecom operators more and more under the all-service operation era, and the evaluation is a key step in the management of IT support system construction. According to the characteristic of IT support system in telecom operators, a evaluation architecture for IT support system is proposed in this paper. Moreover, the authors evaluate the IT support system of CMCC...
Parlay/OSA is a key service provisioning technology in next generation network[1], which opens the functions of telecommunication network to the 3rd service supplier and uses Parlay Framework Interface to ensure the security when the 3rd service supplier accessing to the Parlay/OSA. However, there are still some security vulnerabilities in this technology [2]. In this paper, an improved security protection...
During a long period, there have been a lot of switch problems between TD-SCDMA which is Chinese standard and GSM networks. How to keep their promises to provide users with seamless high-quality coverage, diversification, as well as high-speed business experience? This is the commercial problem that 3G network operators must to overcome in the future. By using K1205 signaling analyzer, the signaling...
