• a system structure diagram for obtaining pre-registration information is provided in the embodiment, which includes the foregoing base station 500 and the high-speed packet data access network HRPD AN600.
• the system for obtaining the pre-registration information provided by the embodiment, so that when the base station needs to obtain the pre-registration information, the base station can automatically send the first message to the HRPD AN, and after receiving the first message, the HRPD AN generates the pre-
• the registration information is sent to the base station, and the second message includes pre-registration information, an identifier of the current cell, and an identifier of the target cell, and the base station associates and stores the pre-registration information, the identifier of the current cell, and the identifier of the target cell.
• the HRPD AN when the base station needs to obtain the pre-registration information, the HRPD AN can generate the pre-registration information according to the first message sent by the base station and send the information to the base station, and does not need to manually configure the pre-registration information on the base station. , thereby simplifying the process of the base station acquiring pre-registration information.
• the technical solution of the present invention which is essential or contributes to the prior art, may be embodied in the form of a software product stored in a readable storage medium, such as a floppy disk of a computer.
• a hard disk or optical disk or the like includes instructions for causing a computer device (which may be a personal computer, a server, or a network device, etc.) to perform the methods described in various embodiments of the present invention.
