Embodiment 1

[0063] In the mobility management of the idle state, the terminal needs to refer to the parameter Qrxlevmin value configured in the cell to determine whether the current cell is a suitable cell for the terminal to camp on. In the current standard definition, the parameter Qrxlevmin value for the cell configuration is frequency specific, so if the terminal only refers to the frequency specific when performing cell selection, it may cause the terminal to repeatedly select between at least two or more cells , if the terminal refers to the signal level value of the cell at the same time, the speed of cell selection will be slow. Based on this, Embodiment 1 of the present invention proposes a mobility management method in an idle state, such as figure 1 The specific processing flow shown is as follows:

[0064] Step 10, the serving cell obtains the Cell specific Qrxlevmin-offset value pre-configured by each neighboring cell.

[0065] In the technical solution proposed by the embo...

Embodiment 2

[0097]In the mobility management of the connected state, the target cell is determined only based on the signal level value of the current serving cell reported by the terminal, the signal level of the neighboring cell measured by the terminal, and the resources of the neighboring cell. In this method, the target cell selected by the network side cannot fully guarantee that the terminal will normally complete random access and other uplink procedures after accessing, so the effectiveness of cell selection is poor. Based on this, Embodiment 2 of the present invention proposes a Mobility management methods such as Figure 4 As shown, the specific process is as follows:

[0098] Step 21, the terminal obtains the signal level values ​​of each neighboring cell of the serving cell.

[0099] Wherein, the terminal may measure the configured measurement objects to determine the signal level values ​​of each neighboring cell.

[0100] Measurement objects can be configured for each nei...

Abstract

The invention provides a method and device for mobility management. The method for mobility management comprises: acquiring the frequency specific Qrxlevmin of each neighbor cell of a serving cell, the cell specific Qrxlevmin-offset pre-configured by each neighbor cell, and the signal level value of each neighbor cell; for any neighbor cell, calculating the sum value of the frequency specific Qrxlevmin and the Cell specific Qrxlevmin-offset of the neighbor cell; and taking the cell with the signal level value larger than the sum value of the frequency specific Qrxlevmin and the Cell specific Qrxlevmin-offset as a candidate target cell. The method and device can be used to solve the problem that a terminal may make ping-pong reselection between two or more cells or terminal access failure occurs when cell selection is made in present mobility management or that the effectiveness is low when cell selection is made in decision switching.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a mobility management method and device. Background technique [0002] Mobility management can assist a Long Term Evolution (English: Long Term Evolution, abbreviation: LTE) communication system to achieve load balancing, provide better user experience, and improve overall system performance. [0003] For ease of illustration, the cell currently serving the terminal, that is, the cell where the terminal currently camps is called a serving cell, and the cell selected or reselected by the terminal is called a target cell. Mobility management functions are mainly divided into two categories: mobility management in idle state and mobility management in connected state. Among them, the mobility management in the idle state is mainly decided by the terminal based on the static parameters configured by the network, and the mobility management in the connected sta...
