Embodiment 1

[0029] figure 2 A flow chart of a method for measuring a neighbor relationship according to an embodiment of the present invention is shown, and the method includes the following steps:

[0030] Step S202: The network side device sends an indication cell to the terminal according to the current state of the terminal, wherein the indication cell carries ANRF measurement indication information;

[0031] When a network side device such as RNC needs to update the neighbor relationship of a certain cell within a period of time or a period, it can send the above indication information element to a certain terminal in the cell, and the indication information element can be carried in the existing sent in downlink messages.

[0032] When the network side device sends the above indication information element, it can proceed in the following manner: the network side equipment determines the current state of the terminal, determines the downlink message according to the current state o...

Embodiment 2

[0057] This embodiment provides a method for detecting neighbor cell relations. This method is described by taking the implementation in UTRA as an example. There are N UEs in a certain UTRA cell A, and 3 UEs have ANRF measurement capabilities, and are used by the RNC Selected as a volunteer to perform the ANRF task, UE 1 is in the dedicated connection state (Cell_DCH state), and can perform UTRA intra-frequency ANRF measurement, UE2 is in the public connection state (Cell_FACH state), and can perform UTRA system internal frequency ANRF measurement , UE3 is in the public paging state (ie, Cell_PCH state), and can perform inter-system ANRF measurement. see image 3 , the method includes the following steps:

[0058] Step S302: RNC commands the UE1 in the Cell_DCH state in the cell A through the relevant information element IE (equivalent to the indication information element in Embodiment 1) in the measurement control message (measurement control message), such as ANRFinformat...

Embodiment 3

[0081] Figure 7 It shows a structural block diagram of a network side device according to an embodiment of the present invention, the network side device may be a radio network controller RNC in UTRAN, and the network side device includes:

[0082] A state determination module 72, configured to determine the current state of the terminal;

[0083] The indication cell sending module 74 is connected to the state determination module 72, and is used to send an indication cell to the terminal according to the current state of the terminal determined by the state determination module 72, wherein the indication cell carries ANRF measurement indication information.

[0084] see Figure 8 The specific structural block diagram of the shown network side equipment indicates that the cell sending module 74 includes:

[0085] A downlink message determining unit 742, configured to determine a downlink message according to the current state of the terminal determined by the state determin...

Abstract

The invention discloses a method for measuring neighbor cell relation and a system thereof, and network side equipment. The method comprises the following steps that: the network side equipment sends indication information element to a terminal according to a current state of the terminal, wherein the indication information element carries automatic neighbor relation functionality (ANRF) measurement indication information; the terminal determines a measurement mode according to the indication information element and performs neighbor cell relation measurement according to the determined measurement mode. By using the method of the invention, problems of lots of system redundancy information and poor system performance caused by using a system broadcast message to trigger the neighbor cell relation measurement can be solved. A triggering mode of the neighbor cell relation measurement is optimized. Signaling costs of the system can be reduced and the system performance can be enhanced.

Description

technical field [0001] The present invention relates to the field of cellular mobile communication, in particular to a method, system and network side equipment for measuring neighbor relationship. Background technique [0002] With the increase in the number of users of cellular mobile communication systems and the improvement of user service requirements, the scale of cellular networks continues to expand, the number of base stations continues to increase, and cellular mobile communication systems of various standards continue to deepen their cooperation with each other. Concomitantly, the management and maintenance of the neighbor relationship of cells in the cellular network has become more and more cumbersome work, so operators expect that the purely manual neighbor relationship management in the past can be automated by the system. [0003] Such as figure 1 As shown, in UTRA (Universal Terrestrial Radio Access Network, universal terrestrial radio access network), UTRA...
