Report method and system for local internet protocol network access capability of home base station

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,...

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-SGW and L-PGW / L-GGSN to the home base station's

However, in the existing 3G and LTE femtocell network architecture, the femtocell does not notify the femtocell gateway and the core network element MME / SGSN of whether it supports LIPA, which causes the core network element and the femtocell gateway to fail to Judging whether the Femtocell supports LIPA service capability information, and the IP address information of the Femtocell

When a Femtocell gateway is deployed in the network, the message that the SGSN / MME creates a user plane bearer for the UE cannot be correctly routed to the Femtocell through the Femtocell gateway, so the existing technology has great limitations
