Embodiment Construction

[0030] Below in conjunction with accompanying drawing, the technical scheme of invention is described in detail:

[0031] Such as figure 1 In the home base station transmission system shown, the mobile equipment in the home network is connected to the home base station HeNB. The HeNB belongs to the user terminal equipment and integrates the main functions of NodeB and RNC. The home base station is connected to the local area network through different access networks such as ADSL, PON, and LAN.

[0032] The connection between the home base station gateway HeNB GW and the HeNB is called a backhaul (Backhaul). Devices in the home network need to pass through the HeNB GW after being transmitted by the access network and the MAN to enter the mobile core network. The HeNB GW is responsible for converging and distributing the signaling and data between the HeNB and the CN, and is also responsible for the registration and access control of the HeNB and UE.

Abstract

The invention relates to a QoS (Quality of Service) method for guaranteeing the multi-service backhaul of a home NodeB and belongs to the technical field of mobile communications. According to the QoS method for guaranteeing the multi-service backhaul of the home NodeB, a home NodeB gateway queries a QoS information table to obtain QoS parameter information of a request service according to the type of the request service of a subscriber, and QoS information occupied when the current subscriber initiates a session is added to the QoS information table; after the home NodeB gateway carries out QoS negotiation, radio access bearer connection between the home NodeB gateway and the home NodeB and radio access bearer connection between the home NodeB and the subscriber are established; and after the subscriber receives core network services, the radio access bearer connection is disconnected, and the QoS information table is modified. The QoS method for guaranteeing the multi-service backhaul of the home NodeB has the advantages that the QoS information table is dynamically updated, and broadband resources occupied by completed sessions are promptly released; and data are buffered according to a priority order, so that various real-time service needs of the home NodeB are guaranteed, and meanwhile, the user experience is improved.

Description

technical field [0001] The invention relates to a QoS method for guaranteeing multi-service backhaul of a home base station, belonging to the technical field of mobile communication. Background technique [0002] With the development of the mobile communication industry, users have increasingly strong demands for high-quality voice and high-speed data services. Therefore, during the standardization process of LTE, the concept and technology of home base station (Home eNodeB) emerged as the times require. As a new idea to solve indoor coverage, it has attracted extensive attention from various operators and equipment manufacturers. [0003] The femtocell is a small base station device for home customer applications, which has the characteristics of low transmission power and small coverage. However, unlike the highly reliable private line backhaul method of the macro base station, the femtocell uses a fixed broadband network as its backhaul network. Such as figure 1 As sho...
