摘要: In the session initiation protocol (SIP), payments have been proposed as a way for vendors to obtain profit from services they provide. Payments in SIP also microbilling and even solution SPAM VoIP systems. Although several proposals exist making SIP, present some limitations when we want pay access real-time services: either are not suitable micropayments or do consider security payment information exchanged. As response these limitations, propose new protocol, LP-SIP, that supports according different models like pay-per-time, session-based, etc. It performs efficiently takes into account secure exchange of information, unlike other existing proposals. Thus, provide lightweight can be used services.
