Embodiment Construction
[0052] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0053] Currently, the three methods mentioned in the background technology allow the terminal to access the core network device through the Internet network or the local area network, but the above three methods have no security protection measures, and there are certain security risks.
[0054] In view of this, the embodiment of the present invention provides a new method for a terminal to access core network equipment. In this method, the terminal can send an attach request message to the MME, and the attach request message carries an APN to request access to the core network. . That is, the terminal can access the core network through the APN, and the APN is usually dedicated,...

The invention discloses a method for a terminal to access core network equipment, the terminal, MME and SAEGW, and is used to improve the security of the terminal accessing core network equipment. The method includes: the terminal sends an attach request message to the MME; wherein the attach request message carries an access point name APN for requesting access to the core network; the terminal receives a feedback message sent by the SAEGW through the MME; wherein the The SAEGW is selected by the MME according to the configuration parameters of the APN, and the feedback message carries the configuration information of the service bearer channel established by the SAEGW; The security management 4A platform sends an authentication message; if the terminal receives the successful authentication message sent by the 4A platform, it sends a login request message to the core network device, and the login request message is used to request access to the core network equipment.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method for a terminal to access core network equipment, a terminal, an MME and a SAEGW. Background technique [0002] In daily work, the staff needs to maintain the core network equipment, which requires connecting the terminal to the core network equipment, and realizing the maintenance of the core network equipment through the terminal. [0003] At present, there are three main methods for terminals to access core network devices. The first method: the terminal accesses the core network device through an Office Automation (OA) office network. The terminal can log in to the core network device through the OA office network, and the OA office network also has a Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol, DHCP) server function to realize the connection with the core network device. The second type: the terminal accesses the core network dev...
