Problems solved by technology

[0007] (1) It is impossible to judge the legitimacy of the user terminal loss report request;
[0008] (2) The network device cannot implement the terminal network lock function, because when the CDMA network machine-card separation terminal is accessing the network, the UIMID information of the card is filled in the user terminal identification field, so that no valid information is carried when the mobile terminal accesses the network. terminal identification information, so the network cannot prevent stolen terminals from accessing the network through terminal identification authentication

Embodiment Construction

[0026] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated. The exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but do not constitute an improper limitation of the present invention.

[0027] The following description of at least one exemplary embodiment is merely illustrative in nature and in no way taken as limiting the invention, its application or uses.

[0028] The following embodiments of the present invention are aimed at the CDMA network system, and the telecom operator actively reports the terminal software and hardware parameters to the CDMA network system through a customized terminal boot self-registration mechanism, based on the real mobile terminal that is actively reported when the mobile terminal is powered on and registered. The relationship between MEID / ESN and IMSI (Internatio...

Abstract

The invention discloses a method and a device for detecting the legality of a mobile terminal in a CDMA network. The method comprises the following steps: receiving an MEID/ESN and an IMSI which are reported by a mobile terminal under the condition of meeting the requirement of boot-up registration message self-reporting; comparing the received MEID/ESN and the received IMSI with a stored MEID/ESN and a stored IMSI; and determining that the mobile terminal is legal if the mapping relationship between the received MEID/ESN and the received IMSI and the mapping relationship between the stored MEID/ESN and the stored IMSI are the same, or determining that the mobile terminal is an illegal user, querying whether the mobile terminal is illegally occupied based on the reported MEID/ESN, and locking the mobile terminal through a CRM if the mobile terminal is illegally occupied. According to the embodiment of the invention, validity and legitimacy of common users can be detected and managed.

Description

technical field [0001] The present invention relates to a CDMA (Code Division Multiple Access, Code Division Multiple Access) network, in particular to a method and device for detecting the legality of a mobile terminal in a CDMA network. Background technique [0002] With the development of mobile communication technology, mobile operators provide users with various flexible and diverse services to meet various personalized service requirements of users. Customized services and packages need to check the validity and legitimacy of the terminal of the user's mobile station to ensure the security of communication services in mobile communications. Through the functions of identifying, monitoring and blocking the mobile station, the legal access of the mobile station to the mobile network and the management of the mobile station under other circumstances are realized. [0003] Currently, in the process of authenticating a CDMA mobile station with machine-card separation in a ...
