Problems solved by technology

[0005] In the Cell Pch state, the serving radio network controller (SRNC, Serving Radio Network Controller) still knows the location of the cell to which the UE belongs, but can only contact the UE through the paging channel (PCH)

Embodiment Construction

[0025] Attached below figure 2 A further detailed description of the implementation of the technical solution:

[0026] Considering the behavior of the UE that frequently updates the state of the cell, there may be the following possibilities:

[0027] 1) UE swings back and forth at the edge of the cell

[0028] 2) UE is in a high-speed motion state

[0029] For the second case, the high-speed motion state can be used to set the threshold, and this threshold can be used to approximate the first case.

[0030] The setting of the threshold should be related to the cell environment and the aforementioned UE behavior.

[0031] Suppose the speed of UE is 50km / h. Taking a dense urban area as an example, the cell radius is 0.57km. If the UE is in the CELL-PCH state or needs to move into the PCH state, it is considered a high-speed UE.

[0032] Then, according to the definition of motion speed and update frequency, the threshold can be obtained:

[0033] In the formula ...

Abstract

The invention relates to a system of testing a frequency-updating of a subdistrict, which is used for moving the user facility with a rapid movement and without the data to send into a Ura PCH state. The system includes: a preplaced module which is used for setting the parameter of the updating frequency state, the parameter of the subdistrict updating times, the parameter of window parameter of the subdistrict updating times and the label parameter of the subdustrict updating times; a writing and updating module which is used for recording system time of the subdistrict updating and parameter of the updating times for the updated subdistrict, and also the number of the smallest updating times; a calculating and dealing module which is used for calculating the existing subdistrict updating frequency which is contrasted with the updating frequency threshold and reset the updating frequency state parameter. By moving the user facility into a Ura PCH state, the frequent subdistrict updating is avoided for the user facility of rapid movement, thereby effectively saving the resources of the systems.

Description

technical field [0001] The present invention relates to a wideband code division multiple access (Wideband Code Division Multiple Access) system (hereinafter referred to as WCDMA) radio network controller (RNC) network element of a kind of algorithm that measures cell renewal frequency, is between Cell Pch and Ura Pch state provides a strategy for migration. Background technique [0002] In a WCDMA system, user equipment (UE) includes two basic operating modes: idle mode and connected mode. The connection mode can be further divided into 4 different states. These service states define the types of physical channels used by the UE. These 4 states are: Cell Dch state, Cell Fach state, Cell Pch state and Ura Pch state. figure 1 The main RRC (Radio Resource Control) business status in the connected mode is given, and the conversion relationship between the idle mode and the connected mode and the possible conversion relationship between the states in the connected mode are also...
