Problems solved by technology

[0005] During the creation process of the present invention, the inventor found at least the following problems in the above-mentioned existing system access technology using indoor base stations: it cannot guarantee that the user equipment can access the indoor base station in the communication scenario where it should be connected to the indoor base station
[0008] The second reason: For UMTS, the reselection of user equipment is based on the neighbor cell relationship, that is, the reselection target of the terminal is limited to the neighbor cells of the cell where it is currently camping, but when the macro cell is the cell , the macro cell does not retain the relationship information of adjacent indoor base station cells, so it may not be possible to find the target indoor base station cell from the macro cell based on these relationship information
In other words, it is difficult to accurately configure the relationship between neighboring cells, and ultimately it is also difficult to reside in the indoor base station cell in the cell reselection mode

no. 1 approach

[0025] First, the present invention provides a first embodiment of a method for accessing an indoor base station, including:

[0026] Step A: Determine whether the user equipment is close to or enters the coverage of the indoor base station;

[0027] Step B: When it is judged that the user equipment has approached or entered the indoor base station coverage area, the network side issues a handover instruction to the user equipment, and the handover instruction instructs the user equipment to handover to the indoor base station cell;

[0028] Step C: The network side switches the user equipment to the indoor base station.

[0029] As can be seen from the first embodiment of the method for accessing indoor base stations provided by the present invention, since it is firstly judged whether the user equipment is close to or within the coverage of the indoor base station, and then the handover instruction is issued, the user terminal that is allowed to access the indoor base statio...

no. 4 approach

[0067] The present invention also provides a fourth embodiment of a method for accessing an indoor base station. The method includes the steps of:

[0068] Step 301: The user equipment judges whether it approaches or enters the coverage area of ​​the indoor base station cell;

[0069] There are multiple methods for judging that the user equipment approaches or enters the coverage of an indoor base station cell, such as the following two:

[0070] 1) When the user equipment receives the information that the indoor base station cell and the cell allow the user equipment to access, it is determined that the user equipment enters the coverage of the indoor base station cell; or

[0071] 2) The user equipment infers that it has entered the allowed access based on the macro cell it currently camps on, the information that the indoor base station allows the user to access, and the information about the macro cell adjacent to the indoor base station cell. Coverage of an indoor base s...

Abstract

The invention discloses a method for accessing indoor base station, network equipment and user equipment. The method for accessing the indoor base station comprises the following steps: determining whether the user equipment is close to or in the coverage range of the indoor base station; transmitting a switch command to the user equipment by the network side when that the user equipment is closeto or in the coverage range of the indoor base station is determined, and that the user equipment is switched to an indoor base station community is indicated by the switch command; and switching theuser equipment to the indoor base station by the network side. The method can improve the selectivity of the user terminal and the possibility for using the corresponding indoor base station community.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for accessing an indoor base station, network equipment and user equipment. Background technique [0002] With the deepening of long-term evolution technology (LTE) research, indoor base station (Home NodeB) or indoor UMTS access point (Universal Mobile Telecommunications System Access Point, UMTS AP) as a wireless access application that can provide high-speed and low-cost services Equipment, more and more international mainstream operators and international equipment manufacturing giants attention. Hereinafter, indoor base stations or indoor UMTS access points are collectively referred to as indoor base stations. [0003] In the prior art, the system structure of an indoor base station applied to indoor access scenarios is as follows: figure 1 shown. In the figure, the indoor base station is routed to the access gateway through the access network after receiving th...
