Embodiment 1
[0032] The system structure of the EVDO system in some special application scenarios (for example, testing, exhibition or AAA server failure), as shown in Figure 3, the EVDO terminal is connected to the BTS, BSC and PDSN of the base station system in turn, where:
[0033] Based on the existing BSC, the BSC adds a local authentication function, that is, when a terminal user initiates a call, the BSC judges whether the terminal has the right to initiate a call, and if so, generates a unique MNID for the terminal according to the existing algorithm ;
[0034] Due to the lack of AAA server equipment, the PDSN can also add a local authentication function, that is, the PDSN only establishes an A-port connection with a terminal that has passed the local authentication. Of course, in other embodiments, authentication-free configuration can also be directly configured on the PDSN.
[0035] The above-mentioned EVDO system implements the specific process of user calling through local aut...
Embodiment 2
[0043] An EVDO system, as shown in Figure 1, differs from the existing EVDO system in that:
[0044] BSC has a built-in switch option. Through the different states of this switch, the EVDO system can provide normal AAA server authentication mode or local authentication mode. The local authentication mode means that when a terminal user initiates a call, the BSC can judge the terminal Whether it has the right to initiate a call, if yes, generate a unique MNID for the terminal according to the existing algorithm.
[0045] PDSN can also add a local authentication function, that is, when the BSC performs local authentication on the terminal that initiates the call, the PDSN also authenticates the terminal that initiates the call, and only establishes an A-port connection with the terminal that has passed the authentication .
[0046] The above-mentioned EVDO system implements the process of terminal calling, as shown in Figure 4, including the following steps:

Abstract
The invention provides a method of an EVDO system for completing a call by local authentication, pertaining to the CDMA20001xEV-DO communication system. In the method of the invention, EVDO terminal initiates a call to a base station system, if the terminal passes the local authentication of the base station system, the base station system generates a unique user identification (MNID) for the terminal by calculation, and then initiates a request of establishing a service connection to a packet data service node (PDSN) through the MNID, and after the service connection is successfully established, the call is completed. The method of the invention is applied to a plurality of special scenes that when a test fails, an exhibition goes wrong, or an AAA server malfunctions, and the like, and ensures that the EVDO terminal can be accessed to a core network normally, thereby being greatly convenient for EVDO terminal users.
Description
technical field [0001] The invention belongs to a CDMA2000 1x wireless high-speed packet data (EV-DO) communication system, and particularly relates to a method for the EVDO system to use local authentication to complete a call. Background technique [0002] Currently, the EVDO system is shown in Figure 1. The base station system includes a base station controller (BSC, BaseStation Controller) and a base station (BTS, Base Transceiver Station). , Accounting) to connect, complete terminal authentication and assign user identification (MNID, Mobile Node Identification) to the EVDO terminal through the AAA server, and the base station system uses the assigned MNID to complete the establishment of the A port, so that the terminal can access the packet data service node ( PDSN, Packet DataServing Node), where the MNID is a unique identifier for the terminal for the PDSN. [0003] In the above-mentioned EVDO system, when the AAA server works normally, the general call establishme...
