Embodiment 1

[0050] figure 2 is a schematic structural diagram of a test system for UE moving between cells according to Embodiment 1 of the present invention, as shown in figure 2 As shown, the system includes: a core network 210 , a LAN switch 220 , two base stations 230 , a base station management station 290 , two radio remote units 240 , two fixed attenuators 250 , a power splitter 270 and a UE 280 .

[0051] The two base stations 230 are connected to the two remote radio units 240 and connected to the core network 210 through the LAN switch 220 . The LAN switch 220 is also connected to the base station management station 290 . The two remote radio units 240 are also connected to the two fixed attenuators 250 respectively. The two fixed attenuators 250 are connected to the power divider 270 . The power splitter 270 is connected to the UE 280 .

[0052] Specifically, the core network 210 is a network that connects service providers and access networks, or connects access networks...

Embodiment 2

[0060] image 3 is a schematic structural diagram of a test system for UE moving between cells according to Embodiment 2 of the present invention, as shown in image 3 As shown, the system described in this embodiment is described based on the system described in the previous embodiment. In this embodiment, the system includes: a core network 310, a local area network switch 320, two base stations 330, a base station management station 390, two In addition to a radio remote unit 340, two fixed attenuators 350, a power divider 370 and UE380, it also includes a controller 360.

[0061] The controller 360 is connected to the base station management station 390, and is used to control the base station management station 390 to read configuration files, and make the base station management station 390 dynamically adjust the serving cell or Cell reference signal power of neighboring cells. Wherein, the configuration file contains program codes for automatically adjusting the cell ...

Embodiment 3

[0063] Figure 4 It is a flow chart of a test method for UE handover between cells according to Embodiment 3 of the present invention, such as Figure 4 As shown, the method comprises the steps of:

[0064] S410: The base station establishes at least two cells.

[0065] S420: The base station management station configures handover test-related parameters of the at least two cells. Specifically, the base station management station needs to configure neighbor cell relationships, measurement events for handover, decision parameters in handover algorithms, and the like.

[0066] S430: The UE searches for a serving cell from the at least two cells, connects to the serving cell, and uses an unconnected cell as a neighboring cell. After starting, the UE searches for the serving cell, starts to attach to the serving cell after the search is successful, and then attaches successfully, that is, connects to the serving cell. At this time, the UE is in a connected state.

Abstract

The invention discloses a test system and a test method of UE (User Experience) moving between communities and relates to the wireless communication field. In the test system of the UE moving between the communities, a base station is connected with at least two remote radio units and connected with a core network through a local area network switch which is connected with a management station of the base station as well; the at least two remote radio units are respectively connected with at least two fixing attenuators which are connected with a power divider; the power divider is connected with the UE; the base station is used for establishing at least two communities, one community of the at least two communities serves as a service community of the UE, and the rest communities serve as neighboring communities; and the management station of the base station is used for dynamically adjusting community reference signal power of the service community or the neighboring communities to trigger the UE to perform reselection or switch between the communities. The test system and the test method of the UE moving between the communities have the advantage of reducing the test complexity and the test costs.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a test system and test method for UE (User Equipment, user equipment) moving between cells. Background technique [0002] In an LTE (Long Term Evolution, long-term evolution) system, moving a UE between cells is an important function. The movement of a UE in the idle state between cells is called inter-cell reselection; the movement of a UE in the connected state between cells is called inter-cell handover. The success rate of UE reselection and handover is an important KPI (Key Performance Indicator) indicator for China Mobile to investigate LTE equipment. Therefore, during the development and testing phase of LTE equipment, LTE equipment manufacturers will build UEs in the laboratory to move between cells. Test environment for functional testing and performance testing. [0003] The trigger condition for the UE to move between cells is that the RSRP (Refe...
