Method and device for establishing cell reselection list

Abstract

The embodiment of the invention discloses a method for establishing a cell reselection and / or frequency list, comprising the following steps of: obtaining a system information which comprises frequency information for a 3G (Third Generation) adjacent cell list and electively comprises frequency information which is used for the cell reselection list and is not used for the 3G adjacent cell list; establishing the cell reselection list and / or a frequency list according to the system information; establishing indexes in an ascending mode in the system information according to the appearing sequence of frequency information for the 3G adjacent cell list in the system information; and when the system information comprises the frequency information which is used for the cell reselection list and is not used for the 3G adjacent cell list, establishing indexes at the bottom of the cell reselection list according to the appearing sequence of the frequency information which is used for the cell reselection list and is not used for the 3G adjacent cell list in the system information. A network and a terminal are used for establishing frequency indexes for the cell reselection list, thereby priority information is issued according to the frequency indexes in the frequency list when a network side issues RAT and frequency priority information, and the cell reselection of the terminal based on priority can be realized.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for establishing a cell reselection list. Background technique [0002] In the GERAN network, the measurement and reselection functions for cells involve the following list: [0003] 1) Broadcast Control Channel Allocation List (Broadcast Control Channel Allocation List, BA list). The BA list is usually only used for the measurement, measurement report and cell reselection functions of the GERAN cell, which includes the frequency and frequency index information of the GERAN neighboring cells. The BA list is constructed by messages SI2 / SI2bis / SI2ter, or SI5 / SI5bis / SI5ter, or constructed by PSI3 and PSI3bis when there is a Packet Broadcast Control Channel (PBCCH). [0004] 2) GSM Neighbor Cell list (GSM Neighbor Cell list, GSM NCL). GSM NCL is also generally only used for GERAN cell measurement, measurement reporting and cell reselection functions. The GSM NCL incl...

Problems solved by technology

Since no frequency index is established in the 3G Cell Reselection list / GPRS 3G Cell Reselection list, priority information cannot be introduced into the 3G Cell Reselection list / GPRS 3G Cell Reselection list, and the 3G Cell Reselection list / GPRS 3G Cell Reselection list is used for The cell reselection list, so when performing cell reselection, since the frequencies contained in the list have no relevant priority information, the terminal cannot perform priority-based cell reselection

[0012] On the other hand, PMO or PCCO usually only modifies the 3G Neighbor Cell list but not the 3G Cell Reselection list / GPRS 3G Cell Reselection list, and the 3G Neighbor Cell list is used for measurement reports, while the 3G Cell Reselection list / GPRS 3G Cell Reselection list It is used for cell reselection, so when the 3G frequency is added or deleted through PMO or PCCO, the network cannot change the terminal's cell reselection related information
