Problems solved by technology

[0004] In actual deployment, operators have different deployment strategies for different carrier frequencies and different systems, and different systems also have different coverage capabilities and mobility support capabilities. For example, in order to meet the requirements of data services in hotspot areas, operators Will consider deploying WIFI, but WIFI has a low ability to support terminal mobility due to its high frequency band (above 2.4G). Not only that, but in the initial deployment stage of LTE, it is usually deployed in some hotspot areas, and the home Base stations are usually deployed on dedicated frequency points for home or hotspot services. In this way, high-speed or medium-speed UEs can receive signals from WIFI or LTE hotspots or home base stations when passing through these hotspot areas. During high-speed or medium-speed movement (such as in a car), these hotspot cells cannot provide continuous services for UE
In addition, in the device-through service (or proximity service) based on the proximity between two or more devices, it is usually not suitable for fast-moving devices due to its sensitivity to communication distance.
However, in the existing mobility technology, UE can only control the measurement ( / scanning) of same-frequency cells and different-frequency (including different-standard) cells according to the signal strength of the serving cell, which is not flexible enough

Embodiment 1

[0098] figure 2 It is the basic flowchart of Embodiment 1 of the present invention; figure 2 shown, including the following steps:

[0099] Step 201, the UE receives the control information sent by the base station, the control information indicates the conditions for the UE to perform measurement and / or reporting, and the conditions include the mobility of the user equipment;

[0100] In step 202, the UE performs measurement and / or reporting when the indicated condition is met.

example 1

[0103] The base station usually performs measurement configuration for the UE in the connected state, and the measurement configuration usually includes one or more measurement objects, such as a specific carrier frequency / standard, and / or a specific cell. UEs can be of different types, including mobile phones, data cards, customer side equipment (CPE), IoT terminals, D2D terminals, etc. The base station can also set the parameter s-measure through the measurement configuration, that is, when the reference signal receiving power (Reference Signal Receiving Power, RSRP) of the primary cell measured by the UE is lower than the set s-measure, the UE performs a measurement of the carrier frequency in the measurement object / standard of measurement. Considering the impact of the mobile speed of the terminal on whether it is necessary to perform measurement (or scanning) and whether it is suitable to select different carrier frequencies / standards, the base station indicates the cond...

example 2

[0110] A UE in an idle (Idle) state obtains a neighboring cell configuration by receiving system information broadcasted by a base station, and the neighboring cell configuration usually includes information of same frequency and / or different frequency (same standard and / or different standard). UEs can be of different types, such as mobile phones, data cards, customer side equipment (CPE), IoT terminals, D2D terminals, etc. The system information may also include the threshold value of the same-frequency measurement, that is, when the cell selection reception level value (Srxlev) of the serving cell measured by the UE>S IntraSearchP and the cell selection quality value (Squal)>S IntraSearchQ , the UE may choose not to perform intra-frequency measurement, otherwise, perform intra-frequency measurement. The system information may also include the threshold value of non-intra-frequency measurement (or inter-frequency / inter-standard measurement), that is, when the cell selection ...

Abstract

The present invention provides a user equipment control method, including: the user equipment configures control information, or receives the control information from the network side, the control information indicates the conditions for the user equipment to perform a specified function, and the conditions include user A mobility condition of the device; the user equipment executes the specified function when the condition is met. The invention also provides user equipment and network side equipment. The present invention decides whether to execute a specified function according to the mobility of the UE, can reduce the times of unnecessary measurement, report, reselection, and handover, and at the same time reduces overhead and is beneficial to power saving.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, to a user equipment control method, user equipment and network side equipment. Background technique [0002] In a wireless cellular communication system, a base station is a device that provides wireless access for user equipment (User Equipment, abbreviated as UE, also referred to as a terminal), and a base station may include one or more serving cells. A cell can provide communication services for UEs in a certain geographical range. Different cells may have different coverage areas. Generally, cells can be divided into macro cells (macro cells), micro cells (pico cells), and Femtocells (femtocells), and correspondingly, base stations providing these cells may also be called macro base stations, micro base stations, and home base stations. [0003] The wireless cellular communication system has gradually developed a variety of standards in the evol...
