METHOD AND SYSTEM FOR SYSTEM INFORMATION ACQUISITION OPTIMIZATION

摘要

The embodiments herein provide a method and system for acquiring modified system information messages in user equipment. The method comprises notifying a modification in system information to user equipment for acquiring the modified system information. The notification comprises adding an SI-Modified flag to a scheduling information element in a system information block type-1, storing the system information, in a network, acquiring and comparing a modified system information with the stored system information, identifying system information modification and transmitting the updated system information to user equipment. The user equipment receives the system information modification notification from the network; decodes the scheduling Info List in the SIB1; processes the system information message in the scheduling Info List; identities the modified system information messages, determines SI window information for the modified system information, acquires the modified system information and updates the stored system information.

1. A method for communicating updated system information, the method comprises steps of:
notifying a modification in a system information to an user equipment; and enabling the user equipment to acquire the modified system information; wherein notifying the system information modification by one or more eNBs comprises of:
transmitting a system information notification;adding a si-Modified flag to a scheduling information element in a system information block type 1 (SIB1);adding a NULL notation to a scheduling information element in a systeminformation block type 1 (SIB1);storing the system information in a network;acquiring a modified system information;comparing the modified system information with the stored system information;identifying and updating a modification information in the updated system information;transmitting the updated system information messages to the user equipment;receiving the system information modification notification in the user equipment;storing the system information received from the network;acquiring SIB1 in the succeeding system information modification period;decoding the schedulingInfoList in the SIB1;processing the system information message in the schedulingInfoList;identifying the modified system information messages in the schedulingInfoList;determining a SI window information for the modified system information messages;acquiring the modified system information messages; andupdating the stored system information.
