In above-described embodiment 1, method for sending information message receiving method in embodiment 2 is combined and can be formed an X2 fault handling method, and in embodiment 1, information transmitting apparatus information receiver in embodiment 2 is combined and can be formed an X2 fault processing system.

Below by application example, above-described embodiment method is illustrated, should be appreciated that following described application example, only for for example, is not intended to limit the present invention.

Application example 1

This example is described in the situation of Home eNodeB normal shutdown or dormancy, and Home eNodeB sends X2 Connection Release Indication message to the flow process of opposite end macro base station, as shown in Figure 6, comprises the following steps:

Step S601: Home eNodeB is about to shutdown or dormancy;

Described shutdown or dormancy refer to Home eNodeB in network, energising etc. under normal circumstances, carry out shutdown or dormancy program.

Step S602: Home eNodeB sends X2 Connection Release indication information to X2 gateway (X2GW) by the message on X2 interface;

Particularly, Home eNodeB is used the existing or newly-increased signaling message on X2 interface to send X2 Connection Release indication information; Preferably, add the release that direct indication information element or multiplexing existing cell indicate X2 to connect in can the existing signaling message on X2 interface, or in the newly-increased signaling message on X2 interface, add the release that direct indication information element indicates X2 to connect.

Existing signaling message on spendable X2 interface comprises base station configuration updating related news (comprising base station configuration updating information (eNB Configuration Update) or base station configuration updating acknowledge message (eNB Configuration Update Acknowledge)), load information (Load Information) Indication message, resource status interaction message (comprising resource status request message (Resource StatusRequest) or resource status response message (Resource Status Response) or resource status updating message (Resource Status Update)), switch related signaling message (comprising handover request message (Handover Request) or switch acknowledgment message (Handover Acknowledge)), signaling message on UE context release message (UE Context Release) and existing other X2 interface,

Signaling message on described newly-increased X2 interface can be a newly-increased X2 signaling message that is specifically designed to indication X2 Connection Release, or other signaling messages on newly-increased X2 interface, is used for indication X2 Connection Release.

After step S603:X2 gateway receives the message on described X2 interface, this message is transmitted to macro base station;

The mode of the message on X2 gateway forwards X2 interface is: according to the destination address carrying in X2 message, this X2 transmission of messages is arrived to correct object base station.

Step S604: macro base station receives after described X2 discharges indication information, discharge to Home eNodeB between X2 connects and the Home eNodeB preserved is relevant information;

The relevant information of Home eNodeB that macro base station is preserved comprises: when Home eNodeB sign, the information of Serving cell, the X2 interface such as information of adjacent cell are set up, macro base station preservation with all information described Home eNodeB X2 join dependency.

To step S604, fault treating procedure is complete.

Step S605: after Home eNodeB start or waking up, Home eNodeB or macro base station are again initiated TNL (Transport Network Layer, transport network layer) and found flow process and X2 Establishing process.

Home eNodeB start refers to that Home eNodeB re-powers and starts working, and described Home eNodeB is waken up, and refers to that Home eNodeB returns to normal work from dormancy;

TNL address discovery flow process and X2 Establishing process can be initiated by Home eNodeB, also can be initiated by macro base station.

Above-mentioned TNL address discovery flow process can adopt the flow process in existing standard, comprise: Home eNodeB or macro base station send base station configuration message transfer (eNB Configuration Transfer) to MME, MME sends MME configuration message transfer (MME Configuration Transfer) to macro base station or Home eNodeB, macro base station or Home eNodeB are replied base station configuration message transfer to MME, and MME replys MME configuration message transfer to Home eNodeB or macro base station.

Above-mentioned X2 Establishing process also can adopt the flow process in existing standard, comprise: Home eNodeB or macro base station send X2 and set up request message to X2 gateway, X2 gateway forwards X2 sets up request message to macro base station or Home eNodeB, and macro base station or Home eNodeB are replied X2 and set up response message Home eNodeB or macro base station.

Application example 2

The X2 that this example is described in Home eNodeB connects abnormal disconnect but S1 connects in normal situation, and Home eNodeB sends X2 Connection Release Indication message to the flow process of base station, opposite end by S1 interface, as shown in Figure 7, comprises the following steps:

Step S701: the X2 of Home eNodeB connects abnormal disconnection, S1 connects normal;

It may be that netting twine by Home eNodeB is pulled out that the X2 of Home eNodeB connects abnormal disconnection, or X2 gateway goes wrong, or other network failure causes.

Step S702: Home eNodeB sends base station configuration message transfer (eNB ConfigurationTransfer) to MME;

Different according to the implementation of macro base station, this base station configuration message transfer can comprise the cell of direct indication X2 Connection Release, also can not comprise the cell of direct indication X2 Connection Release.

Step S703:MME sends MME transmission configuration message (MME Configuration Transfer) to macro base station after receiving base station configuration message transfer;

If the cell that base station configuration message transfer comprises direct indication X2 Connection Release, MME configuration message transfer also comprises this directly cell of indication X2 Connection Release, if base station configuration message transfer does not comprise the cell of direct indication X2 Connection Release, MME configuration message transfer does not comprise the cell of direct indication X2 Connection Release yet.

Step S704: after macro base station receives MME configuration message transfer, discharge to Home eNodeB between the information that X2 connects and the Home eNodeB preserved is relevant;

The implementation of macro base station can be receive MME configuration message transfer after, the relevant information of Home eNodeB that X2 Connection Release indication information release based on wherein connects to the X2 between Home eNodeB and preserves, now base station configuration message transfer and MME configuration message transfer need to carry the cell of the direct X2 of indication Connection Release; Or the implementation of macro base station can be also receive MME configuration message transfer after, based on this MME configuration message transfer directly discharges to Home eNodeB between the information that X2 connects and the Home eNodeB preserved is relevant, now base station configuration message transfer and MME configure the cell that message transfer does not need to carry the direct X2 of indication Connection Release;

To step S704, fault treating procedure is complete.

Step S705: after home base station network recovers normally, Home eNodeB or macro base station are initiated TNL address discovery flow process and X2 Establishing process again.

Described home base station network recovers normally to refer to can normally work Home eNodeB and being connected of other network elements, mainly refers to that in this example X2 connects;

TNL address discovery flow process and X2 Establishing process can be initiated again by Home eNodeB, also can again be initiated by macro base station.

Above-mentioned TNL address discovery flow process and X2 Establishing process all can adopt the flow process in existing standard, referring to application example 1.
