Problems solved by technology

In this way, the user equipment will also perform a large number of operations such as cell measurement, access, handover, and reselection on private cells without authorization, increasing the RA / TA / LA (routing area / tracking area / local area, routing area / tracking area / local area) update signaling flow and access, handover and reselection signaling flow, thus increasing the power consumption of user equipment and the signaling load of the network

Embodiment 1

[0047] In this embodiment, the network side indicates whether the cell is a private cell by sending the physical cell identifier to the user equipment.

[0048] The specific method provided by this embodiment is as follows:

[0049] Step 101, the network side uses part of the scrambling code sequence in the cell scrambling code as the dedicated scrambling code for the HNB cell, and sends to the user equipment a physical cell identifier that can identify whether the cell is an HNB, that is, the cell physical ID after division of the scrambling code sequence.

[0050] We know that the scrambling codes of a cell have a total of 218 bits, that is, 262,143. For fast cell switching, k=0, 1,..., 8191 sequences are taken, and these cells are divided into 512 scrambling code sequences group, each cell has one and only one primary scrambling code. Therefore, part of the scrambling code sequence can be designated as a dedicated scrambling code for the HNB cell, and a scrambling code uni...

Embodiment 2

[0058] In this embodiment, the network side indicates whether the cell is a private cell by sending HNB cell type indication information to the user equipment. The method provided in this embodiment specifically includes:

[0059] Step 201, the network side sends HNB cell type indication information to the user equipment. The private cell type indication information includes: HNB cell list, HNB cell type indication information element, system information group SIB with private cell information, and cell ID with private cell type indication bit.

[0060] The following is a detailed introduction:

[0061] (1) The HNB cell type indication information is: HNB cell list.

[0062] The network side identifies the HNB cell through the HNB cell list, that is, identifies the HNB cell with a separate HNB cell list. For example, a separate HNB cell list item is separated from the macro cell list in the SIB, so that the user equipment stores and updates the cell list variable in the use...

Embodiment 3

[0084] This embodiment provides a communication system, such as image 3 As shown, the communication system includes: a network device 300 and a user device 400 .

[0085] The network device 300 sends cell identification information to the user equipment 400; the user equipment 400 receives the above cell identification information, and identifies a private cell, such as an HNB cell, according to the cell identification information, and initiates an operation on the private cell with authority.

[0086] Further, the above-mentioned network device 300 uses part of the scrambling code sequence in the cell scrambling code as a dedicated scrambling code for a private cell, or multiplexes a part of the scrambling code sequence in the cell scrambling code as a dedicated scrambling code for a private cell, or uses the private cell The scrambling code sequence in the scrambling code extension part is used as a dedicated scrambling code for the private cell. The above user equipment 4...

Abstract

The present invention provides a method, a communication network and a device for user equipment to initiate an operation on a private cell. The above method includes: receiving cell identification information, the cell identification information is used to indicate whether the cell is a private cell, the cell identification information includes a physical cell identification, and the physical cell identification identifies the private cell through a dedicated scrambling code of the private cell The dedicated scrambling code for the private cell includes a scrambling code sequence specially assigned to the private cell in the cell scrambling code; identifying the private cell according to the cell identification information; and initiating an operation on the private cell with authority. Through the above technical solution, the user equipment is enabled to initiate an operation on the identified private cell with authority, avoiding the increase in power consumption of the user equipment and the increase in power consumption of the user equipment caused by the user equipment being unable to identify the private cell and initiating an operation on the private cell without authority. Problems with increased network load.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to the technology for user equipment to initiate operations on private cells. Background technique [0002] With the development of the third-generation 3G mobile communication technology, femtocell base stations, also known as home base stations (Home NodeB, HNB) or 3G access points, have appeared, which are home indoor coverage base stations and enterprise-level internal coverage Base stations and other constrained networks emerged. The 3G femtocell can be seamlessly connected with the original network equipment of the operator, and a large number of mobile services are absorbed by the femtocell, which can reduce the number of macro cells of the operator, and save equipment investment and maintenance costs for the operator. [0003] Recently, the concept of CSG (Closed Subscriber Group, Closed Subscriber Group) has been introduced. User equipment that is subscribed...
