Problems solved by technology

[0009] In the existing technical solution, if the current network does not have enough bandwidth resources to provide services for the user equipment, the user equipment must switch to other available networks around or back off and wait for a period of time until the network has enough bandwidth resources before accepting the macro base station or home network. The service provided by the base station, which greatly increases the service time of the user equipment

Embodiment Construction

[0023] refer to figure 1 , the admission control method of the present invention is as follows:

[0024] Step 1, add the file download service type and add an optional item in the establishment reason content in the RRC connection establishment request signaling message, and its content indicates the file size to be downloaded. When the establishment reason content is the file download service type, the user equipment Put the download file size into this optional.

[0025] The options included in the establishment reason in the existing mechanism include: emergency call, high priority access and other types.

[0026] When the RRC connection is successfully established, the macro base station or the home base station will allocate an ID number for the RRC connection.

[0027] In step 2, the user of the macro base station initiates an RRC connection request to the macro base station.

[0028] The macro base station user initiates a file download service request to the macro b...

Abstract

A femtocell admission control method based on LTE includes the following steps that (1) a macro base station user planning to be connected to a macro base station initiates a request for a file downloading service to the macro base station, and if having enough bandwidth resources, the macro base station accepts the access request of the macro base station user and provides the file downloading service for the macro base station user; (2) if the macro base station does not have enough bandwidth resources, the macro base station user initiates the request for the file downloading service to a surrounding femtocell, and if having enough bandwidth resources, the femtocell accepts the request of the macro base station user and provides the file downloading service for the macro base station user; (3) if the femtocell does not have enough bandwidth resources to provide the file downloading service for the macro base station user, whether the macro base station user is allowed to be connected or not is determined according to femtocell users already connected to the femtocell, sizes of files downloaded by the macro base station user and time delay influence on femtocell user services after access of the macro base station user.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and specifically relates to a method for controlling admission of users by a home base station when a macro base station in LTE coexists with a home base station based on LTE. Background technique [0002] LTE (Long Term Evolution, long-term evolution) is a technical standard formulated by 3GPP (The3rdGenderationPartnershipProject). quasi-4G" technology. At the same time, LTE also supports TDD (Time Division Duplex) and FDD (Frequency Division Duplex) two working modes. The research on LTE aims to provide users with: higher data transmission rate, higher cell capacity, lower delay, and lower costs for users and operators. [0003] LTE consists of two parts, the core network and the access network. The core network is mainly divided into three parts: MME (MobilityManagementEntity), S-GW (ServingGateway) and P-GW (PublicDataNetworkGateway). The access network is composed of macro...
