Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that although the physical interfaces of CSIM/RSIM and USIM user cards are the same, due to the different file structures in the user cards, CSIM/RSIM and USIM user cards cannot be used universally.
This means that

Abstract

The embodiment of the invention discloses a method and a system for accessing to a long term evolution network (LTE) based on a preferred roaming list (PRL). The method comprises the steps that an LTE terminal searches a network access message; the LTE terminal inquires a System Record table in a PRL file, and acquires corresponding PLMN (Public Land Mobile Network) attributes of an SID (System Identifier) and an NID (Network Identifier) in the network access message based on the System Record table; the LTE terminal maps the SID and the NID in the network access message into an MCC (Mobile Country Code) and an MNC (Mobile Network Code) respectively; the MCC and the MNC are merged to generate a PLMN serial number; a PLMN list is reconstructed by substituting the corresponding PLMN attributes with the PLMN serial number; and the LTE terminal conducts LTE network access according to the PLMN list. With the adoption of the method and the system, a CDMA (Code Division Multiple Access) terminal can conduct the LTE network access based on the PRL.

Description

technical field [0001] The invention relates to communication technology, in particular to a method and system for accessing a long-term evolution network based on a preferred roaming list. Background technique [0002] With the development of communication technology, future code division multiple access (Code Division Multiple Access, hereinafter referred to as: CDMA) technology will evolve to Long Term Evolution (hereinafter referred to as: LTE) technology, and current CDMA terminal users will probably use LTE business. [0003] However, the current CDMA terminal uses a CDMA Subscriber Identity Module (CDMA Subscriber Identity Module, hereinafter referred to as: CSIM) or a Removable User Identity Module (hereinafter referred to as: RUIM) as a user card, and its network information, such as : information such as system, frequency, network number, priority, etc., is stored in a preferred roaming list (Preferred Roaming List, hereinafter referred to as: PRL). The LTE termi...
