Problems solved by technology
[0014] The present invention is proposed in view of the problems in the related art that when the user equipment accesses its restricted home base station, the user equipment cannot be paged, resulting in communication failure or waste of paging resources. For this reason, the main purpose of the present invention It is to provide an improved method and system for user equipment to access a home base station, so as to solve at least one of the above problems

Embodiment Construction
[0033] Functional Overview
[0034] Embodiments of the present invention provide a scheme for user equipment to access a home base station. When a UE with emergency services moves to a closed-mode home base station that does not authorize the UE, the UE needs to immediately notify the core network of the current location of the UE. The core network The network saves the location; the UE notification method can be a location update (TAU / RAU), or a normal service packet data network (Packet Data Network, referred to as PDN) connection interruption request or a normal service packet data protocol (Packet Data Protocol, referred to as Release request for PDP) context. When the core network receives the downlink data that needs to be sent to the user, the core network will page the user at the above location. When the home base station is located in the LTE core network, the above message is Tracking Area Update (Tracking Area Update), and / or normal service PDN connection release ...

A method and system for accessing a Home NodeB by a user equipment are disclosed in the present invention. When the user equipment moves into a service area of a restricted Home NodeB by which it is not authorized, the above-mentioned method includes that: the user equipment learns through detection that the Home NodeB to which the service area, into which it moves, belongs is a restricted Home NodeB (S501); the user equipment sends a message to a core network, wherein the message carries the current location information of the user equipment (S503); the user equipment receives a paging request initiated by the core network and sets up the connection with the restricted Home NodeB, wherein the paging request is initiated through a Home NodeB subsystem corresponding to the location information when the core network obtains downlink data that needs to be sent to the user equipment (S505). According to the technical solution provided by the present invention, the above-mentioned user equipment can be effectively paged, thus making the communication successful and avoiding the waste of paging resource effectively.
Description
technical field [0001] The present invention relates to the communication field, in particular, to a method and system for user equipment to access a home base station. Background technique [0002] Home base stations are small, low-power base stations that are deployed in indoor places such as homes and offices. Insufficient coverage of conventional cellular wireless communication systems. The advantages of femto base stations are as follows: affordable, convenient, low power output, plug and play, broadband access, use of single-mode terminals, etc. [0003] The femto base station may be applied in a third generation (3Generation, 3G for short) or long term evolution (Long Term Evolution, LTE for short) mobile communication network. When a home base station is applied in a 3G network, it is referred to as Home Node B (Home Node B, HNB for short); when a home base station is applied in an LTE network, it is referred to as Home Evolved Node B (Home Evolved Node B, referred...
