Problems solved by technology

Although using this solution will not affect the performance of the original macro network, due to the small coverage area of ​​the Nanocell, this violates the TA setting principle, and will cause a significant increase in the number of TAU when the user moves between the Macrocell and the Nanocell, and this TAU is concentrated on a small number of base stations, namely Nanocell and surrounding Macrocell, which affects network performance
[0010] From this point of view, the current existing technical solutions cannot achieve the purpose of reducing the number of TAUs while reducing the paging volume carried by the Nanocell, thereby affecting the performance of the network

Embodiment 1

[0067] According to an aspect of the embodiments of the present invention, a method for configuring a tracking area is provided. The method first obtains the type of the cell where the user equipment is currently camped on and the working status information of the user equipment; then, according to the current camping The type of the remaining cell and the working state information determine the tracking area list; finally, send the tracking area list to the user equipment, so that the user equipment determines its own tracking area according to the tracking area list. Wherein, the method can be implemented in the mobility management entity, and can also be implemented through the gateway.

[0068] Such as figure 1 As shown, the method includes:

[0069] Step S11 , acquiring the type of the cell where the user equipment is currently camping on and the working state information of the user equipment.

[0070] The current camping cell of the user equipment may be a macro cell,...

Embodiment 2

[0099] According to another aspect of the embodiments of the present invention, a tracking area configuration method is also provided, such as figure 2 As shown, the method includes:

[0100] Step S21, receiving the tracking area list determined by the mobility management entity according to the type of the cell where the user equipment currently resides and the working status information.

[0101] Wherein, the cell where the user equipment is currently camped on may be a macro cell, or a micro cell or a pico cell corresponding to a micro base station or a pico base station deployed within the coverage of the macro cell. The working status information includes: the status information of the user equipment initially accessing the macro cell after powering on, the status information of the user equipment initially connecting to the micro cell or pico cell after powering on, the user equipment moving from the macro cell to the micro cell or pico cell and Status information of t...

Embodiment 3

[0108] According to another aspect of the embodiments of the present invention, a tracking area list configuration device is also provided, such as image 3 As shown, the device 300 configured in the tracking area list includes:

[0109] An obtaining module 301, configured to obtain the type of the cell where the user equipment currently resides and the working status information of the user equipment;

[0110] A processing module 303, configured to determine a tracking area list according to the type and working status information of the currently camped cell;

[0111] The sending module 305 is configured to send a tracking area list to the user equipment, so that the user equipment determines its own tracking area according to the tracking area list.

[0112] Optionally, the working status information includes: status information of user equipment initially accessing a macro cell after powering on, status information of user equipment initially accessing a micro cell or a p...

Abstract

The invention provides a tracking area list configuration method, device and system. The tracking area list configuration method comprises steps of obtaining a type of a cell where a user device currently resides, determining a tracking area list according to the type and a working state of the current residing cell, transmitting a tracking area list to the user device in order to make the user device determine the tracking area of the user device according to the tracking cell list. The tracking area list configuration method, device and system can dynamically configure the tracking area list for the user device by targeting the user device residing cell which can be a macrocell, a microcell or a picocell and user device working state information, reduce updating times of the tracking area when the user device moves among the macrocell and the microcell or the picocell under a condition that the tracking areas of the macro cell and the microcell or the picocell in the adjacent areas are different, and dramatically reduce a load of a paging amount of the microcell or the picocell.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method, device and system for configuring a tracking area list. Background technique [0002] Tracking Area (TA) is a concept newly established by Long Term Evolution (LTE) or System Architecture Evolution (SAE) system for location management of user equipment. The function of TA is similar to the Location Area (LA) and Routing Area (RA) of the third-generation mobile communication technology. Since the LTE system is mainly designed for packet domain functions, TA is closer to the concept of RA. [0003] In addition, for a TA, a TA can contain one or more cells, and a cell can only belong to one TA, and a TA is identified by a TA code (Tracking Area Code, TAC), and the system message (SIB1) of the TAC in the cell broadcast periodically. [0004] The concept of a TA list is introduced in the LTE system, and a TA list includes 1 to 16 TAs. A mobility management enti...
