[0050] This embodiment is applicable to a 3G HNB network architecture. In this network architecture, the HNB is connected to the CN through the HNB GW.

[0051] Figure 7 is a flow chart corresponding to the first embodiment according to the embodiment of the present invention, such as Figure 7 As shown, the following steps S701 to S704 are included:

[0052] In step S701, the source HNB establishes an SCTP connection with the HNB gateway.

[0053] In step S702, the source HNB sends a registration message to the HNB gateway, and the message carries information required for establishing a direct interface between HNBs.

[0054] In step S703, if the HNB GW accepts the registration request of the HNB, the HNB GW will save the content carried in the registration request message, which includes the information that the home base station has the ability to establish a direct interface.

[0055] In step S704, the HNB GW sends a registration request response to the HNB, and the me...

[0057] This embodiment is applicable to a 3G HNB network architecture. In this network architecture, the HNB is connected to the CN through the HNB GW. In this embodiment, an Iuh interface message is newly added, which is used to transfer information required for establishing a direct interface between HNBs, and may be named as an HNB configuration message.

[0058] Figure 8 It is a flow chart corresponding to the second embodiment according to the embodiment of the present invention, such as Figure 8 As shown, the following steps S801 to S804 are included:

[0059] In step S801, the source HNB establishes an SCTP connection with the HNB gateway.

[0060] In step S802, the source HNB sends a HNB configuration message to the HNB gateway, and the message carries information required for establishing a direct interface between the HNBs.

[0061] In step S803, the HNB GW saves the content carried in the HNB configuration message.

[0064] This embodiment is applicable to the network architecture in which the LTE HeNB is connected to the CN through the HeNB GW. Specifically, the home base station reports information required for establishing a direct interface between base stations to the home base station gateway.

[0065] Figure 9 It is a flow chart corresponding to the third embodiment according to the embodiment of the present invention, such as Figure 9 As shown, the following steps S901 to S904 are included:

[0066] In step S901, the source HeNB establishes an SCTP connection with the HNB gateway.

[0067] Step S902, the source HeNB sends an S1 interface establishment request message to the home base station gateway, the message carries the information required to establish the direct interface between the home base stations, the information includes the capability information of the home base station to establish the interface between the base stations, and optionally includes the direct interf...

Abstract

The present invention discloses a method for reporting the information required for establishing a direct interface between home NodeBs, and the home NodeB. The method comprises: establishing a stream control transmission protocol (SCTP) connection between the home NodeB and a home NodeB gateway or a core network element mobile management entity (MME); and reporting by the home NodeB the information required for establishing the direct interface between the home NodeBs through the SCTP connection. The present invention solves the problem that the home NodeB gateway or the core network element can not acquire the information required for establishing the direct interface between the home NodeBs, and achieves the effect of reducing the signaling transmission load in the network caused when a user performs switching between the home NodeBs.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for reporting information required for establishing a direct interface between home base stations and a home base station. Background technique [0002] Femtocells are small, low-power base stations that are mainly deployed in indoor places such as homes and offices. Insufficient coverage of cellular wireless communication systems. Femtocells have the advantages of affordability, convenience, low power output, and plug-and-play. [0003] Depending on the interface provided, the home base station can be connected to a 3G or LTE network architecture. The invention is applicable to both 3G and LTE home base stations. figure 1 It is a 3G network architecture diagram based on related technologies, such as figure 1 As shown, in the 3G network architecture, the base station and the core network are connected through the Iu interface. figure 2 It is a network architecture...
