Embodiment 1

[0038] According to an embodiment of the present invention, a CSG cell selection method is provided. This method is used to process when the user chooses to camp on the CSG cell.

[0039] figure 2 Shows the flow of the CSG cell selection method according to Embodiment 1 of the method of the present invention, as shown in figure 2 As shown, the CSG cell selection method according to the first method embodiment of the present invention includes the following steps (step S202 to step S204):

[0040] Step S202, the UE searches for available CSG cells;

[0041] Step S204, if the UE judges that the searched CSG cell is a pre-designated CSG cell, and the signal quality of the searched CSG cell meets the predetermined requirements, then select the searched CSG cell as the cell to camp on. Preferably, the predetermined requirement may be a minimum call quality requirement.

[0042] The procedure of the above processing will be described in detail below.

[0043] If there is a no...

Embodiment 2

[0079] According to the embodiment of the method, a CSG cell reselection method is provided.

[0080] Before executing the CSG cell reselection method, this embodiment also provides two types of trigger conditions for the UE to perform CSG cell reselection evaluation. The two types of conditions are as follows: The first type is triggered internally by the UE. The signal quality of the cell does not meet the requirements, and the scheduled cell reselection periodic timer expires; the second type is when the CSG information in the system broadcast information changes.

[0081] Figure 4 Shows the flow of the CSG cell reselection method according to the second embodiment of the method of the present invention, as shown in Figure 4 As shown, the CSG cell reselection method according to the second method embodiment of the present invention includes the following steps (step S402 to step S404):

[0082] Step S402, when the UE starts cell reselection, the UE searches for an avail...

Abstract

The invention discloses CSG(Content Service Gateway) cell selection / reselection method and device. The CSG cell selection method comprises the following steps of: searching a usable CSG cell by UE (User Equipment) under the condition that the user selects to reside in the CSG cell; and selecting the CSG cell as a residing cell by the UE if the searched CSG cell is judged to be the preset designated CSG cell and the signal quality of the CSG cell meets the preset requirement. By using the invention, the UE can effectively select the CSG cell and is convenient to flexibly apply CSG services.

Description

technical field [0001] The present invention relates to the communication field, in particular to a closed subscriber group (Closed Subscriber Group, CSG for short) cell selection / reselection method and device. Background technique [0002] Currently, mobile communication technology is faced with the problem of providing users with higher data rates, providing better coverage and greater capacity for the network. [0003] In order to solve the above problems, the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) launched the wireless access network long-term evolution project (Long Term Evolution, referred to as LTE), and the evolved access technology (Evolved-Universal Terrestrial Radio Access, referred to as E-UTRA) and evolved access network (Evolved-Universal Terrestrial Radio Access Network, referred to as E-UTRAN), and the evolution of packet domain core network oriented to the entire network protocol (Internet Protocol, refer...
