Problems solved by technology

Since there is no frequency index established in the 3G Cell Reselection list / GPRS 3G CellReselection list, priority information cannot be introduced into the 3G Cell Reselection list / GPRS 3GCell Reselection list, and the 3G Cell Reselection list / GPRS 3G CellReselection list is used for cell reselection Therefore, when performing cell reselection, since the frequencies contained in the list do not have 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 CellReselection 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 is Used for cell reselection, so when adding or deleting 3G frequencies through PMO or PCCO, the network cannot change the terminal's cell reselection related information

Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025]In the embodiment of the present invention, both the network side and the terminal need to establish a cell reselection list. For the convenience of description, the embodiments of the present invention are all described in terms of a process in which a terminal establishes a cell reselection list. Those skilled in the art may obtain the corresponding method for establishing a cell reselection list on the network side according to the description of the embodiments without being creative. The cell reselection list may be a 3GCell Reselection list and / or a GPRS 3G Cell Reselection list.

[0026] A method for establishing a cell reselection list in an embodiment of the present invention is as follows: figure 1 shown, including

[0027] Obtaining system information, the system information includes frequency informa...

Abstract

The embodiment of the present invention discloses a method for modifying a cell reselection list. The method includes obtaining a cell modification message, modifying a 3G neighboring cell list according to the cell modification message, and obtaining a modified 3G neighboring cell list; according to the modified The 3G neighbor cell list updates the cell reselection list, wherein the updated cell reselection list includes the frequency and / or cell information in the modified 3G neighbor cell list, and the cell reselection list can be modified through PMO and PCCO messages.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and device for modifying 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, BAlist). 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 ...
