Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0020] At present, there are limitations in preventing SIP terminal accounts from being illegally stolen: the account of the SIP terminal is bound to the IP address, and the mobility of the SIP terminal is limited; the SIP terminal obtains the IP address dynamically through DHCP, so it is impossible to determine whether the SIP terminal account has been impersonated. Therefore, there is a security risk for effective identification; if the SIP terminal account is leaked, there will be serious consequences of stolen calls and high call charges. The present invention is to solve the above problems.

[0021] SIP is not an easy protocol to implement security. The use of intermediaries, multi-faceted trust relationships, expected usage betwee...

Abstract

The invention provides a method for safely calling a session initiation protocol (SIP) terminal based on a user bound number authentication mechanism. The method comprises the following steps that: a user template is arranged on an SIP server, and an SIP account number is bound with a specified telephone number of a user; a user sends a login request out, and the SIP server searches the corresponding user template after receiving the login request; if the template does not exist, normal registration process is performed; if the template exists, the SIP server starts a call limit for the user; after a receiving authority is acquired, the corresponding SIP terminal corresponding to the user is required to be called by using the bound telephone number through the SIP server; if the SIP server detects that the corresponding SIP terminal is called by using the telephone number bound in the template, the call limit of the SIP terminal is lifted; and if the corresponding SIP terminal is not called by using the bound telephone number, the call limit is kept. By the method, a phenomenon that an illegal user has a free call on other's expenses through an illegal means can be effectively avoided, the SIP terminal can selects to refuse an authentication call of the telephone number, and additional telephone expenses cannot be generated.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a method for realizing safe dialing by a SIP terminal based on a binding number authentication mechanism, specifically adopting a mechanism based on binding a SIP terminal and other phone numbers of a user on a SIP server to realize the anti-theft calling function . Background technique [0002] The mode of prior art one is to utilize SIP (Session Initiation Protocol, session initiation protocol) authentication to carry out anti-theft calling, when UA (UserAgent, user agent (SIP terminal system), including user agent client UAC (UserAgentClient) and user agent server UAS (UserAgentserver) two parts) is online, and when it is registered in its local management domain, it can establish a TLS (Transport Layer Security) connection with its SIP server. The SIP server provides a certificate for the UA, and the site identified by the certificate must match the domain that the UA wa...
