Problems solved by technology

[0005] However, in the current network architecture, since the core network element SGSN/MME does not know the specific information of the Femtocell, that is to say, the core network does not know the IP address of the Femtocell and whether the Femtocell has the ability to support LIPA services Therefore, there are two problems in the prior art: on the one hand, the core network cannot determine whether to establish a bearer for the LIPA service request initiated by the home base station; on the other hand, if the MME/SGSN accepts the LIPA service request initiated by the home base station, it cannot Routing the bearer establishment request message sent to L-S...

Embodiment 1

[0084] Method Embodiment 1: In the case of a 3G system network architecture, the network element of the core network is an SGSN.

[0085] In this embodiment, the signaling process of the Iuh interface is used to complete the process of reporting the LIPA capability of the home base station to the home base station gateway and the core network. After the home base station gateway receives the LIPA service-related information of the home base station, it transmits the information through the IU interface message to the core network element SGSN. This method is applicable to the network architecture where the 3G femtocell is connected to the core network through the femtocell gateway, such as figure 1 shown, including the following steps:

[0086] Step 701: The Femtocell sends a registration request message to the Femtocell Gateway. The message not only carries information such as the Femtocell ID, Femtocell name, and Femtocell location, but also information about whether the Fe...

Embodiment 3

[0101] Method Embodiment 3: In the case of an LTE system network architecture, the network architecture at this time includes a home base station gateway, and the network element of the core network is an MME.

[0102] This embodiment is a flow chart of using the signaling process of the S1 interface to complete the flow chart of reporting the LIPA capability of the home base station to the home base station gateway and the core network. It is sent to the core network element MME. This method is applicable to the network architecture where the LTE home base station is connected to the core network through the home base station gateway, such as image 3 shown, including the following steps:

[0103] Step 901: The Femtocell sends an S1 interface establishment request message to the Femtocell gateway. In addition to carrying information such as the Femtocell identifier, Femtocell name, and Femtocell location, the message also needs to carry information about whether the Femtocel...

Abstract

The invention discloses a report method for local internet protocol network access capability of home base station, comprising a step that a home base station reports the capability information indicating whether to support the local internet protocol access (LIPA) service via a home base station gateway, or directly reports the capability information to a core network. The invention also discloses a report system for local internet protocol network access capability of home base station; in the system, a report unit at the home base station side is used for reporting the capability information indicating whether to support the LIPA service via the home base station gateway, or directly reporting the capability information to the core network. The method and system of the invention realize the report of the capability information indicating whether to support the LIPA service by the home base station.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for reporting the local Internet Protocol (IP, Internet Protocol) network access capability of a home base station. Background technique [0002] In the current third-generation digital communication (3G) network architecture, the base station is connected to the core network through the Iu interface, and the signaling transmission of the Iu interface adopts IP bearer; the Iu interface is the link between the wireless access network and the core network in the 3G system. Interface. In the current Long Term Evolution (LTE, Long Term Evolution) network architecture, the network structure is flat, and the radio access network and the core network are connected through the S1 interface; among them, the S1 interface is the link between the radio access network and the core network in the LTE system. between interface. [0003] Femtocell is a small,...
