Method for storing cell system information across network

Abstract

The invention discloses a method for storing the system information of a cross-network cell, including the following steps: (1) frequency point and cell physical layer mark are adopted as index key words to mark a cell table; (2) whether the value mark of a received main system message block or the value mark of a scheduling block is identical to a stored value mark is checked; if the marks are different, scheduling information of other common system information block in the main system message block or the scheduling block can be stored in the cell table, and the value mark of the main system message block is updated; moreover, according to the public land mobile network (PLMN) mark information of the main system message block, the pointing relationship between the cell table and a PLMN table is set up; (3) according to the effective range and type mark of a current common system information block, a common system information block designated by location is searched in the cell table or the PLMN table. The invention, which realizes a storage proposal for saving memory and convenient search, reduces the time for visiting a SIB and accelerates cell dwell process.

Description

technical field [0001] The present invention relates to the field of mobile communication terminals, and more specifically relates to a method for storing system information of multiple cross-network cells when a user terminal switches to a different network in a third-generation mobile communication system. Background technique [0002] RRC (Radio Resource Control, radio resource management) in UTRAN (Universal Terrestrial Radio Access Network, universal mobile telecommunications system terrestrial access network) broadcasts system information messages to UEs (user terminals). The system information message is composed of information units, carrying the information of the access stratum and the non-access stratum. [0003] The non-access layer information includes: operator information, CN domain information, etc.; the access layer information includes: location registration area information, cell information, channel information, cell selection and reselection information,...
