Embodiment 1

[0090] This embodiment describes that only the priority list is provided in the RRC connection release message without redirection information. In this case, the UE can only select the last connected cell to camp on for cell selection. At this time, if the dedicated priority information of (at least one) non-serving frequency point is indicated in the RRC connection release message, then the priority information of the serving frequency point must appear in the same RRC connection release message. Subsequent cell reselection process.

[0091] This scenario can be expressed as follows: when the UE receives the RRC connection release message, the frequency point of the cell where the UE is located is f1, and the system information of the cell provides public priority information f1, f2, f3 of several frequency points, and at the same time the RRC connection release message Without redirection information, the cell can only select the last connected cell for cell selection campin...

Embodiment 2

[0093] This embodiment describes that the RRC connection release message not only provides a priority list, but also provides redirection information, then the UE will first choose to camp on a cell of a different frequency or technology according to the redirection information, in this case If the dedicated priority information of (at least one) non-serving frequency point is indicated in the RRC connection release message, then the priority information of the redirected frequency point must appear in the same RRC connection release message to ensure subsequent cell re-registration selection process.

[0094] This scenario can be expressed as follows: when the UE receives the RRC connection release message, the frequency point of the cell where the UE is located is f1. After the connection is released, the UE is redirected to a cell under the frequency point f2. The system information of the cell provides several frequency points. Public priority information f1, f2, f3, if th...

Embodiment 3

[0109] This embodiment describes that when the RRC connection release message only provides a priority list without redirection information, the UE can only select the last connected cell for cell selection camping. In this case, if the RRC connection release message indicates (at least one) dedicated priority information of non-serving frequency points, but the priority of the serving frequency point is not provided by the RRC connection release message, then use the priority information of the current frequency point provided in the system information to ensure that subsequent cell reselection process.

[0110] This scenario can be expressed as follows: when the UE receives the RRC connection release message, the frequency point of the cell where the UE is located is f1, and the system information of the cell provides public priority information f1, f2, f3 of several frequency points, and at the same time the RRC connection release message Without redirection information, th...

Abstract

The invention discloses a method and a system of reselection priority indication in a cell, comprising the following steps: determining special priority information without carrying service frequency points in a message released by wireless resource control connection, wherein the service frequency points are released by wireless resource control connection; and indicating priority information ofthe service frequency points when determining that the message released by wireless resource control connection indicates the special priority of at least one non-service frequency point. The method and the system solves the problems that after receiving the message released by the wireless resource control connection, when only having special priority of the non-service frequency point without any priority information of the service frequency points, user equipment can not carry out the processes of measurement and reselection of any pilot frequency/pilot technology normally, guarantees the smooth implementation of user equipment in the processes of following parking and call establishment and enhances the sensitivity of user experience.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and system for cell reselection priority indication. Background technique [0002] 1. A brief introduction to the content of the RRC (Radio Resource Control, radio resource control) connection release message. [0003] The RRC connection release message optionally includes redirection information and cell reselection priority information. The redirection information is used to designate a specific frequency point to the UE (User Equipment, user equipment), and after the UE releases the RRC connection, the cell selection can only be performed on this frequency point. The cell reselection priority information is used to indicate to the UE the priority of the frequency points that can perform cell reselection next. [0004] 1. When the RRC connection release message does not contain redirection information and only contains cell reselection priority information, afte...
