Embodiment 1

[0050] figure 1 The schematic diagram of the network layout of the LTE system is shown. There is an S1 interface between the core network and the base station (macro base station), and an X2 interface between adjacent base stations; the home base station can be directly connected to the core network, or it can be connected through the home base station gateway and The core network is connected, and there is no X2 interface between the home base stations and between the home base station and the macro base station. The UE is located in a cell under the jurisdiction of the source base station and is in a connected state. The UE has a list of CSG cells that are allowed to access. Here, the source base station may be a macro base station or a home base station.

[0051] The UE handover process is as follows figure 2 Shown:

Embodiment 2

[0068] In the WCDMA system, the schematic diagram of its network layout can be found in image 3 , there is an Iub interface between the radio network controller RNC and the base station to which it belongs, there is no interface between the base stations, and there is an Iu interface between the RNC and the core network. The home base station is connected to the core network through the home base station gateway, the interface between the home base station and the home base station gateway is Iuh, and the interface between the home base station gateway and the core network is Iu. The UE is located in a cell under the jurisdiction of the source base station or the source HNB and is in a connected state, and the UE has a list of CSG cells that are allowed to access. The RNC to which the source base station belongs is called the source RNC, and the home base station gateway to which the source home base station belongs is called the source home base station gateway.

[0086] figure 1 The schematic diagram of the network layout of the LTE system is shown. There is an S1 interface between the core network and the base station (macro base station), and an X2 interface between adjacent base stations; the home base station can be directly connected to the core network, or it can be connected through the home base station gateway and The core network is connected, and there is no X2 interface between the home base stations and between the home base station and the macro base station. The UE is located in a cell under the jurisdiction of the source base station and is in a connected state. The UE has a list of CSG cells that are allowed to access. Here, the source base station may be a macro base station or a home base station. In this embodiment, the target home base station (closed mode) is directly connected to the core network.

Abstract

A method and system for processing failure of a handover to a CSG cell are provided, which are used to solve the technical problem of the interface signaling consumption and network performance degradation caused by the handover of a UE to a non-member CSG cell. When the UE is not an authorized subscriber of a target CSG cell, a core network notifies a source NodeB of the non-member failure information, thereby enforcing the UE to update an allowed CSG list to prevent the source NodeB or a source Radio Network Controller (RNC) or a source HNB from sending a handover required signaling to identical target cells, or prevents the UE from sending a handover request to identical target cells frequently by setting a delay timer, or the source NodeB or the source RNC or the source home NodeB prevents the UE from handing over to a neighboring CSG cell with identical CSG Identity (ID) under the condition of being able to acquire the CSG ID of the target CSG cell. The method and system can prevent sending the handover request signaling to identical target CSG cells again after the handover failure of the UE, thereby reducing the signal consuming between the interfaces and enhancing the performance of the network.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a processing method and system for failing to switch to a closed subscriber group cell. Background technique [0002] In the construction of modern wireless network systems, indoor coverage has become the top priority of network construction. On the one hand, a suitable indoor coverage solution can maximize the role of the network and create greater value for operators. On the other hand, it can also It greatly saves the operator's network construction cost and truly realizes low investment and high return. As a result, a wireless access device called Home NodeB (Home NodeB, HNB) emerges as the times require. As the exclusive resources of private users, femtocells are deployed in private places such as families, groups, companies or schools. They can provide users with various high-speed wireless access services and provide preferential tariffs, and at the same time make up f...
