Embodiment

For making the application's object, technical scheme and advantage clearer, referring to the accompanying drawing embodiment that develops simultaneously, the application is described in further detail.

The method of the transmission RNASP message that the application proposes is included in the method for twocouese transmission RNSAP public-measurement message between Home eNodeB and RNC or RNSAP information exchange message.Due to RNSAP information exchange message and the transfer process of RNSAP public-measurement message between RNC and Home eNodeB similar, therefore, the RNSAP public-measurement message of mainly take is below example, sets forth the transmission plan of this class message between Home eNodeB and RNC.

The application relates to three kinds of important network equipments: Home eNodeB, femto gateway and RNC.Wherein:

(1) Home eNodeB

Home eNodeB (femtocell) is a kind of femtometer cellular basestation, and towards house or corporate environment design, Home eNodeB has been concentrated traditional base station and the partial function of RNC.In the application, with macrocell interconnected in, Home eNodeB may initiatively be initiated public-measurement request to adjacent macrocell, meanwhile, Home eNodeB is also supported the public-measurement request from macrocell to Home eNodeB.

(2) femto gateway

Femto gateway is the intermediate transit point between RNC and Home eNodeB, completes the Mapping and Converting from Iur to Iurh, guarantees interconnecting between RNC and Home eNodeB.

When transmitting public metrical information, femto gateway is responsible for the mapping from Iur to Iurh, realizes and on Iurh interface, transmits Iur public-measurement message by the connection-oriented mode of RNA or the connectionless mode of RNA.

(3)RNC

The application of family base station system need accomplish not affect the design of original macrocell, provides as much as possible new technical scheme to meet user's demand within the scope of family base station system.Therefore, in the application, for the RNC in macrocell, the interface of transmitting public metrical information remains unchanged, and still adopts the connection-oriented mode of signaling connection control protocol (SCCP:Signaling Connection and Control Part) to transmit.

One family base-station gateway can be connected with a plurality of Home eNodeB, and, can be connected with a plurality of RNC.

In order to transmit RNASP message between Home eNodeB and RNC, the application provides three kinds of technical schemes, is explained respectively below.As previously mentioned, the part that relates in the following description RNSAP public-measurement message is only used to illustrate.

The first scheme: set up in advance Iurh and be connected between Home eNodeB and femto gateway, and adopt the connection-oriented mode of RNA to transmit RNSAP message.

Particularly: when determining that the adjacent area of Home eNodeB is macrocell, between femto gateway and Home eNodeB, setting up Iurh is connected, and in setting up the process of Iurh connection, by femto gateway, be that this Home eNodeB and macrocell distribute a Context identifier, this Context identifier does not belong to specific user, but the RNA that is exclusively used in transmission RNSAP message for identifying between this Home eNodeB and femto gateway is connected, in this RNA connection, adopt connection-oriented mode to transmit the RNSAP message between this Home eNodeB and this macrocell.If both needed between this Home eNodeB and macrocell to transmit RNSAP public-measurement message, also need to transmit RNSAP information exchange message, can connect and transmit by same RNA.The Context identifier connecting for being different from common RNA, the application is by its called after common context sign (common context ID).

If need to communicate by letter between one family base station and one family base-station gateway, must first set up Iurh and connect, this be Home eNodeB with femto gateway between the basis of communicating by letter; And RNA connection is not to set up, when needs adopt the connection-oriented mode of RNA to communicate, just need between Home eNodeB and femto gateway, set up RNA and be connected, otherwise Home eNodeB and femto gateway can adopt the connectionless mode of RNA to communicate.

This scheme specifically comprises the following steps:

Step 1: distribute common context ID in the process of setting up in advance Iurh connection.

This step has two kinds of preferably implementations, is described in detail respectively below.

The first preferably implementation is: by Home eNodeB, initiatively to femto gateway, initiate RNA Iurh and set up request, femto gateway distributes common context ID in RNA Iurh process of establishing, as shown in Figure 2, comprises the following steps:

Step 201: be adjacent area when Home eNodeB detects macrocell, and when not setting up Iurh between Home eNodeB and be connected, to femto gateway, send RNA Iurh and set up request (RNA Iurh Setup Request) message, this RNA Iurh sets up in request message and comprises: the cell ID of Home eNodeB and the sign of macrocell.

Step 202: femto gateway receives that RNA Iurh sets up after request message, according to sign wherein, judge, when finding that Target cell is macrocell, femto gateway distributes a common context ID for this Iurh connects, for adopting the connection-oriented mode of RNA to transmit public-measurement message etc.

In this step, femto gateway also will record the corresponding relation of the sign of this common context ID and macrocell.

Step 203: femto gateway is included in RNA Iurh by distributed common context ID and sets up in response (RNA Iurh Setup Response) message, sends to Home eNodeB.

After Home eNodeB is received, preserve this common context ID and the sign of the macrocell that reports in step 201.Home eNodeB and femto gateway can find with this common context ID the sign of context that corresponding RNA is connected and corresponding macrocell, and, the context that femto gateway can also find the SCCP of corresponding Iur interface to connect with this common context ID, hereinafter will be elaborated to this.

The second preferably implementation is: by femto gateway, initiatively to Home eNodeB, initiate RNA Iurh and set up request, femto gateway distributes common context ID in RNA Iurh process of establishing, as shown in Figure 3, comprises the following steps:

Step 301: when femto gateway finds that according to gateway configuration the adjacent cell of Home eNodeB is macrocell, and when not setting up Iurh between Home eNodeB and be connected, first be that this Home eNodeB and macrocell distribute a common context ID, this common context ID is used for adopting the connection-oriented mode of RNA to transmit public-measurement message etc.

Step 302: femto gateway sends RNA Iurh to Home eNodeB and sets up request message, and this RNA Iurh sets up in request message and comprises: the cell ID of Home eNodeB, the sign of macrocell and common context ID.

Step 303: Home eNodeB receives that RNA Iurh sets up after request message, preserves the sign of common context ID in this message and corresponding macrocell, and to Home eNodeB, replys RNA Iurh and set up response message.

Step 2: transmit RNSAP public-measurement message between Home eNodeB and RNC.

In this step, different according to triggering main body, there are two kinds of situations, a kind of situation is that the RNC in macrocell triggers public-measurement, another kind of situation is that Home eNodeB triggers public-measurement, is described in detail respectively below.

The first situation: when RNC triggers public-measurement, transmit the signaling process figure of RNSAP public-measurement message as shown in Figure 4 between Home eNodeB and RNC, comprise the following steps:

Step 401:RNC first check its to femto gateway between whether exist the relevant SCCP of RNC to connect, if there is no, RNSAP public-measurement initialization request is included in SCCP connection request message and sends to femto gateway; If existed the SCCP that RNC is relevant to connect, in the transfer of data connecting at this SCCP, RNSAP public-measurement initialization request message sent to femto gateway, and skip over this step and step 402.

As previously mentioned, for public network, femto gateway is equivalent to a RNC, and, for transmitting the signaling of public-measurement message, connect for two RNC, therefore, in this step, RNC first need to check its to femto gateway between whether exist the SCCP that RNC is relevant to connect.

Step 402: femto gateway is received after SCCP connection request message, distributes SCCP connection identifier, and reply SCCP connection request acknowledge message to RNC for the SCCP that is about to set up connects.

RNC is when initiating SCCP connection request message, also will distribute a SCCP connection identifier for this SCCP connects, this sign is different from the SCCP connection identifier that femto gateway distributes, RNC and femto gateway are preserved respectively the SCCP connection identifier that distributed separately, can find the context of corresponding SCCP connection by SCCP connection identifier separately.For femto gateway, by this SCCP connection identifier, can determine the sign of corresponding Iur interface and macrocell.

Step 403: femto gateway sends to Home eNodeB by RNA connect message by RNSAP public-measurement initialization request message by the connection-oriented mode of RNA.

In the application, " by the connection-oriented mode of RNA " transmitted a certain RNSAP message and referred to: in the transmitting procedure of this RNSAP message, use common context ID to identify, thereby make message receiver without this RNSAP message is resolved, the common context ID only connecting by this RNA can find corresponding information; For example: the context that femto gateway can find the SCCP of corresponding Iur interface to connect according to common context ID;

" by the connectionless mode of RNA " transmitted a certain message and referred to: in the transmitting procedure of this message, do not use common context ID;

" by the connection-oriented mode of SCCP " transmitted a certain message and referred to: in the transmitting procedure of this message, use SCCP connection identifier to identify.

Step 404: Home eNodeB adopts the connection-oriented mode of RNA to reply RNSAP public-measurement initialization response message to femto gateway in RNA transfer of data.

Step 405: femto gateway is received after the RNSAP public-measurement initialization response message of Home eNodeB, send to RNC by the connection-oriented mode of SCCP in SCCP transfer of data.

If Home eNodeB initialization public-measurement failure, according to the processing mode of abnormal conditions shown in Fig. 4, process, that is: in step 404 ', Home eNodeB adopts the connection-oriented mode of RNA to send RNSAP public-measurement initialization failed message to femto gateway in RNA data transmission procedure; In step 405 ', femto gateway sends to RNC by the connection-oriented mode of SCCP by this RNSAP public-measurement initialization failed message in SCCP transfer of data.

After step 405, if Home eNodeB has RNSAP public-measurement, report will be transferred to RNC, perform step 406, in RNA transfer of data, by the connection-oriented mode of RNA, first send to femto gateway, then by femto gateway, perform step 407, in SCCP transfer of data, by the connection-oriented mode of SCCP, send to RNC.

When Home eNodeB can not be reported RNSAP public metrical information to RNC again, processing mode according to abnormal conditions shown in Fig. 4 is processed, that is: Home eNodeB sends to femto gateway by the connection-oriented mode of RNA by RNSAP public-measurement failure Indication message in RNA transfer of data, and then by SCCP, is connected this RNSAP public-measurement is unsuccessfully indicated and sent to RNC in SCCP transfer of data by femto gateway.

So far, finish flow process shown in Fig. 4.

The second situation: when family's base station triggers public-measurement, transmit the signaling process figure of RNSAP public-measurement message as shown in Figure 5 between Home eNodeB and RNC, comprise the following steps:

Step 501: Home eNodeB is used the common context ID distributing when Iurh connection is set up, sends RNSAP public-measurement initialization request message by RNA connect message to femto gateway.

Step 502: femto gateway is received after RNSAP public-measurement initialization request message, check its to RNC between whether exist the SCCP relevant with this Home eNodeB to be connected, if there is no, RNSAP public-measurement initialization request message is included in SCCP connection request message and sends to RNC, and distribute SCCP connection identifier (CID for this SCCP connects; If existed the SCCP relevant to this Home eNodeB to connect, in the transfer of data connecting at this SCCP, RNSAP public-measurement initialization request message sent to femto gateway, and skip over this step and step 503.

This flow process is the public-measurement being triggered by Home eNodeB, follow-up RNC need to send public-measurement report to this Home eNodeB, owing to connecting by same SCCP, RNC can only report to one family base-station transmission public-measurement, therefore, in this step, femto gateway first need to check its to RNC between whether exist the SCCP relevant with this Home eNodeB to be connected.

Due in step 1, when femto gateway distributes common context ID, recorded the corresponding relation of the sign of common context ID and macrocell, and in the context that SCCP connects, have a sign of macrocell, SCCP connection identifier information, therefore, can judge by the sign of macrocell and between RNC, whether exist the SCCP relevant with this Home eNodeB to be connected accordingly, if existed, by the corresponding relation of setting up accordingly between common context ID and SCCP connection identifier, in subsequent step, femto gateway is resolved without the RNSAP message to receiving, and only by transmitting the common context ID of this RNSAP message, can determine and which connect this RNSAP message of transmission by, if there is no, by initiating, set up the process that SCCP connects, and set up the SCCP connection identifier of this SCCP connection and the corresponding relation between common context ID.

Step 503:RNC receives after RNSAP public-measurement initialization request message, connects acknowledge message RNSAP public-measurement initialization response is sent to femto gateway by SCCP.

Step 504: femto gateway is received after RNSAP public-measurement initialization response message, send to Home eNodeB by the connection-oriented mode of RNA in RNA transfer of data.

As described in step 502, femto gateway is by the corresponding relation of setting up between SCCP connection identifier and common context ID, therefore, when from being connected with the SCCP of RNC while receiving RNSAP message, without this RNSAP message is resolved, the SCCP connection identifier directly connecting according to SCCP can be determined corresponding common context ID, and find corresponding RNA context, then in corresponding RNA transfer of data, by the connection-oriented mode of RNA, RNSAP message is sent to Home eNodeB.

If RNC initialization public-measurement failure, according to the processing mode of abnormal conditions shown in Fig. 5, process, that is: in step 503 ', RNC connects in acknowledge message RNSAP public-measurement initialization failed message is sent to femto gateway at SCCP, femto gateway finds corresponding RNA context by SCCP connection identifier again, then in step 504 ', RNSAP public-measurement initialization failed message is sent to Home eNodeB by the connection-oriented mode of RNA.

After step 504, if RNC has RNSAP public-measurement, report will be transferred to Home eNodeB, perform step 505, in SCCP transfer of data, by the connection-oriented mode of SCCP, first send to femto gateway, then by femto gateway, perform step 506, in RNA transfer of data, by the connection-oriented mode of RNA, send to Home eNodeB.

When RNC can not be again to Home eNodeB report public metrical information, processing mode according to abnormal conditions shown in Fig. 5 is processed, that is: RNC is connected RNSAP public-measurement failure Indication message is sent to femto gateway by SCCP, and then in RNA transfer of data, this RNSAP message is sent to Home eNodeB by the connection-oriented mode of RNA by femto gateway.

So far, finish flow process shown in Fig. 5.

More than describe the embodiment of the application's the first scheme in detail, the advantage of this scheme is:

(1) by common context ID, adopt the connection-oriented mode of RNA to transmit between Home eNodeB and femto gateway, make femto gateway when receiving the RNSAP public-measurement message sending over from Home eNodeB, without the particular content of resolving message, only based on context sign can index out the context that the SCCP of its correspondence on Iur interface connects, and has improved the efficiency of transmission of messages;

(2) object that Iurh connection is set up is exactly to be the RNSAP transmission of messages distribution Context identifier between corresponding macrocell and Home eNodeB, pre-assigned strategy makes can reduce time delay when RNSAP transmission of messages, improves the treatment effeciency of femto gateway.

The first scheme below the application being provided is elaborated.

First scheme: when needs transmit RNSAP message, just set up RNA between Home eNodeB and femto gateway and be connected, and distribute common context ID, be used for transmitting RNSAP message.Only being to set up RNA from the difference of the first scheme connects and distributes the opportunity of common context ID different.

Under this programme, different according to triggering main body, there are two kinds of situations, a kind of situation is that the RNC in macrocell triggers public-measurement, another kind of situation is that Home eNodeB triggers public-measurement, is described in detail respectively below.

The first situation: when RNC triggers public-measurement, transmit the signaling process figure of RNSAP public-measurement message as shown in Figure 6 between Home eNodeB and RNC, comprise the following steps:

Step 601:RNC first check its to femto gateway between whether exist the relevant SCCP of RNC to connect, if there is no, RNSAP public-measurement initialization request is included in SCCP connection request message and sends to femto gateway; If existed the SCCP that RNC is relevant to connect, in the transfer of data connecting at this SCCP, RNSAP public-measurement initialization request message sent to femto gateway, and skip over this step and step 602.

Step 602: femto gateway is received after SCCP connection request message, distributes SCCP connection identifier, and reply SCCP connection request acknowledge message to RNC for the SCCP that is about to set up connects.

Meanwhile, femto gateway distributes a common context ID for connection-oriented transport between this Home eNodeB and macrocell.

Step 603: femto gateway sends to Home eNodeB by RNA connect message by RNSAP public-measurement initialization request message by the connection-oriented mode of RNA.

Step 604: Home eNodeB is replied RNSAP public-measurement initialization response message by the connection-oriented mode of RNA to femto gateway in RNA transfer of data.

Step 605: femto gateway is received after the RNSAP public-measurement initialization response message of Home eNodeB, without parsing RNSAP message, the context that the Context identifier only connecting by RNA can find the SCCP of corresponding Iur interface to connect, thus by the connection-oriented mode of SCCP, RNSAP public-measurement initialization response message is sent to RNC.

If Home eNodeB initialization public-measurement failure, according to the processing mode of abnormal conditions shown in Fig. 6, process, that is: in step 604 ', Home eNodeB adopts the connection-oriented mode of RNA to send RNSAP public-measurement initialization failed message to femto gateway in RNA data transmission procedure; In step 605 ', femto gateway sends to RNC by the connection-oriented mode of SCCP by this RNSAP public-measurement initialization failed message in SCCP transfer of data.

After step 605, if Home eNodeB has RNSAP public-measurement, report will be transferred to RNC, perform step 606, in RNA transfer of data, by the connection-oriented mode of RNA, first send to femto gateway, femto gateway is received after RNSAP message, without parsing this RNSAP message, the context that the Context identifier only connecting by RNA can find the SCCP of corresponding Iur interface to connect, thus by the connection-oriented mode of SCCP, the report of RNSAP public-measurement is sent to RNC.

When Home eNodeB can not be reported RNSAP public metrical information to RNC again, processing mode according to abnormal conditions shown in Fig. 6 is processed, that is: Home eNodeB sends to femto gateway by the connection-oriented mode of RNA by RNSAP public-measurement failure Indication message in RNA transfer of data, and then by SCCP, is connected this RNSAP public-measurement is unsuccessfully indicated and sent to RNC in SCCP transfer of data by femto gateway.

So far, finish flow process shown in Fig. 6.

The second situation: when family's base station triggers public-measurement, transmit the signaling process figure of RNSAP public-measurement message as shown in Figure 7 between Home eNodeB and RNC, comprise the following steps:

Step 701: before preparing to initiate public-measurement to macrocell, between Home eNodeB inspection and this macrocell, whether exist RNA to be connected, if have, show to be now assigned common context ID, by RNA connect message, to femto gateway, send RNSAP public-measurement initialization request message, and follow-up flow process is identical with Fig. 5, does not repeat them here; If no, send RNSAP public-measurement initialization request message by the connectionless mode of RNA to femto gateway.

After femto gateway receives that Home eNodeB passes through RNSAP public-measurement initialization request message that the connectionless mode of RNA sends, for this Home eNodeB and macrocell distribute common context ID, and record the corresponding relation of the sign of this common context ID and macrocell.

Step 702: femto gateway is received after RNSAP public-measurement initialization request message, check its to RNC between whether exist the SCCP relevant with this Home eNodeB to be connected, if there is no, RNSAP public-measurement initialization request message is included in and in SCCP connection request message, sends to RNC and connect distribution SCCP connection identifier (CID for this SCCP; If existed the SCCP relevant to this Home eNodeB to connect, in the transfer of data connecting at this SCCP, RNSAP public-measurement initialization request message sent to femto gateway, and skip over this step and step 703.

Because femto gateway is when distributing common context ID, recorded the corresponding relation of the sign of common context ID and macrocell, and in the context that SCCP connects, have a sign of macrocell, SCCP connection identifier information, therefore, can judge by the sign of macrocell and between RNC, whether exist the SCCP relevant with this Home eNodeB to be connected accordingly, if existed, by the corresponding relation of setting up accordingly between common context ID and SCCP connection identifier, in subsequent step, femto gateway is resolved without the RNSAP message to receiving, and only by transmitting the common context ID of this RNSAP message, can determine and which connect this RNSAP message of transmission by, if there is no, by initiating, set up the process that SCCP connects, and set up the SCCP connection identifier of this SCCP connection and the corresponding relation between common context ID.

Step 703:RNC receives after RNSAP public-measurement initialization request message, connects acknowledge message RNSAP public-measurement initialization response is sent to femto gateway by SCCP.

Step 704: femto gateway is received after RNSAP public-measurement initialization response message, send to Home eNodeB by the connection-oriented mode of RNA in RNA transfer of data.

As described in step 702, femto gateway is by the corresponding relation of setting up between SCCP connection identifier and common context ID, therefore, when from being connected with the SCCP of RNC while receiving RNSAP message, without this RNSAP message is resolved, the SCCP connection identifier directly connecting according to SCCP can be determined corresponding common context ID, and find corresponding RNA context, then in corresponding RNA transfer of data, by the connection-oriented mode of RNA, RNSAP message is sent to Home eNodeB.

If RNC initialization public-measurement failure, according to the processing mode of abnormal conditions shown in Fig. 7, process, that is: in step 703 ', RNC connects in acknowledge message RNSAP public-measurement initialization failed message is sent to femto gateway at SCCP, femto gateway finds corresponding RNA context by SCCP connection identifier again, then in step 704 ', RNSAP public-measurement initialization failed message is sent to Home eNodeB by the connection-oriented mode of RNA.

After step 704, if RNC has RNSAP public-measurement, report will be transferred to Home eNodeB, perform step 705, in SCCP transfer of data, by the connection-oriented mode of SCCP, first send to femto gateway, then by femto gateway, perform step 706, in RNA transfer of data, by the connection-oriented mode of RNA, send to Home eNodeB.

When RNC can not be again to Home eNodeB report public metrical information, processing mode according to abnormal conditions shown in Fig. 7 is processed, that is: RNC is connected RNSAP public-measurement failure Indication message is sent to femto gateway by SCCP, and then in RNA transfer of data, this RNSAP message is sent to Home eNodeB by the connection-oriented mode of RNA by femto gateway.

So far, finish flow process shown in Fig. 7.

More than describe the embodiment of the application's first scheme in detail, the advantage of this scheme is:

(2) when needs carry out RNSAP transmission of messages, inborn ability is joined Context identifier, does not need to revise the flow process of existing RNAIurh process of establishing.

The third scheme below the application being provided is elaborated.

The third scheme: adopt the connection-oriented mode of SCCP to transmit RNSAP message between femto gateway and RNC, between femto gateway and Home eNodeB, adopt the connectionless mode of RNA to transmit RNSAP message.

Similarly, different according to triggering main body, this programme also has two kinds of situations, and a kind of situation is that the RNC in macrocell triggers public-measurement, and another kind of situation is that Home eNodeB triggers public-measurement, is described in detail respectively below.

The first situation: when RNC triggers public-measurement, transmit the signaling process figure of RNSAP public-measurement message as shown in Figure 8 between Home eNodeB and RNC, comprise the following steps:

Step 801:RNC first check its to femto gateway between whether exist the relevant SCCP of RNC to connect, if there is no, RNSAP public-measurement initialization request is included in SCCP connection request message and sends to femto gateway; If existed the SCCP that RNC is relevant to connect, in the transfer of data connecting at this SCCP, RNSAP public-measurement initialization request message sent to femto gateway, and skip over this step and step 802.

Step 802: femto gateway is received after SCCP connection request message, distributes SCCP connection identifier, and reply SCCP connection request acknowledge message to RNC for the SCCP that is about to set up connects.

Step 803: femto gateway takes out RNSAP public-measurement initialization request message from the transfer of data of SCCP connection request message or SCCP connection, and sends to Home eNodeB by RNA without the mode that connects (RNA connectionless).

Step 804: Home eNodeB is replied RNSAP public-measurement initialization response message by the connectionless mode of RNA to femto gateway.

Step 805: femto gateway is received after the RNSAP public-measurement initialization response message of Home eNodeB, this message is resolved, obtain and measure sign, by measurement, identify and determine corresponding SCCP connection identifier, and the context of index SCCP connection, then by the connection-oriented mode of SCCP, RNSAP public-measurement initialization response message is sent to RNC.

Because flow process shown in Fig. 8 is to take RNSAP public-measurement message as example describes, therefore, in this step, be that the measurement of obtaining in RNSAP public-measurement initialization response message identifies to search corresponding SCCP connection identifier.For RNSAP information exchange message, this step should be to obtain the information exchange sign of the corresponding message exchange occurrence of RNSAP information exchange message, searches SCCP connection identifier.Under this programme, both of these case can be described as:

When receive from RNC RNSAP message time, femto gateway is resolved this RNSAP message, obtains the sign of the corresponding event of this RNSAP message, and according to the sign of the corresponding event of this RNSAP message, the sign of searching corresponding Home eNodeB;

When receive from Home eNodeB RNSAP message time, femto gateway is resolved this RNSAP message, obtain the sign of the corresponding event of this RNSAP message, and according to the sign of the corresponding event of this RNSAP message, search corresponding SCCP connection identifier.

If the failure of Home eNodeB initialization public-measurement, processes according to the processing mode of abnormal conditions shown in Fig. 8, that is: in step 804 ', Home eNodeB sends RNSAP public-measurement initialization failed message by the connectionless mode of RNA to femto gateway; In step 805 ', femto gateway sends to RNC by the connection-oriented mode of SCCP by this RNSAP public-measurement initialization failed message in SCCP transfer of data.

After step 805, if Home eNodeB has RNSAP public-measurement, report will be transferred to RNC, perform step 806, by the connectionless mode of RNA, first send to femto gateway, femto gateway is received after the report of RNSAP public-measurement, and it is resolved, and obtains and measures ID, the context connecting by measuring ID index SCCP, then sends to RNC by the connection-oriented mode of SCCP by the report of RNSAP public-measurement.

When Home eNodeB can not be reported RNSAP public metrical information to RNC again, processing mode according to abnormal conditions shown in Fig. 8 is processed, that is: Home eNodeB is unsuccessfully indicated RNSAP public-measurement and is sent to femto gateway by the connectionless mode of RNA, and then by femto gateway, RNSAP public-measurement is unsuccessfully indicated and resolved, obtain and measure ID, the context connecting by measuring ID index SCCP, is then unsuccessfully indicated RNSAP public-measurement and sends to RNC by the connection-oriented mode of SCCP.

So far, finish flow process shown in Fig. 8.

The second situation: when family's base station triggers public-measurement, transmit the signaling process figure of RNSAP public-measurement message as shown in Figure 9 between Home eNodeB and RNC, comprise the following steps:

Step 901: Home eNodeB sends RNSAP public-measurement initialization request message by the connectionless mode of RNA to femto gateway.

Step 902: after femto gateway is received public-measurement initialization request message, check its to RNC between whether exist the SCCP relevant with this Home eNodeB to be connected, if there is no, RNSAP public-measurement initialization request message is included in SCCP connection request message and sends to RNC, and distribute SCCP connection identifier for this SCCP connects; If existed the SCCP relevant to this Home eNodeB to connect, in the transfer of data connecting at this SCCP, RNSAP public-measurement initialization request message sent to femto gateway, and skip over this step and step 903.

Step 903:RNC receives after RNSAP public-measurement initialization request message, connects acknowledge message RNSAP public-measurement initialization response is sent to femto gateway by SCCP.

Step 904: femto gateway is received after RNSAP public-measurement initialization response message, this message is resolved, obtain and measure ID, and by measuring the sign of ID index Home eNodeB, and by the connectionless mode of RNA, RNSAP public-measurement initialization response message is sent to Home eNodeB.

If RNC initialization public-measurement failure, according to the processing mode of abnormal conditions shown in Fig. 9, process, that is: in step 903 ', RNC connects in acknowledge message RNSAP public-measurement initialization failed message is sent to femto gateway at SCCP, femto gateway is resolved this message, obtain and measure ID, and by measuring the sign of ID index Home eNodeB, then in step 904 ', adopt the connectionless mode of RNA to send to corresponding Home eNodeB RNSAP public-measurement initialization failed message.

After step 904, if RNC has RNSAP public-measurement, report will be transferred to Home eNodeB, perform step 905, in SCCP transfer of data, by the connection-oriented mode of SCCP, first send to femto gateway, then by femto gateway, this RNSAP public-measurement report is resolved, obtain and measure ID, and by measuring the sign of ID index Home eNodeB, and perform step 906, by the connectionless mode of RNA, the report of RNSAP public-measurement is sent to Home eNodeB.

When RNC can not be again to Home eNodeB report public metrical information, processing mode according to abnormal conditions shown in Fig. 9 is processed, that is: RNC is connected RNSAP public-measurement failure Indication message is sent to femto gateway by SCCP, femto gateway is resolved this message, obtain and measure ID, and by measuring the sign of ID index Home eNodeB, then this RNSAP message is sent to Home eNodeB by the connectionless mode of RNA.

So far, finish flow process shown in Fig. 9.

More than describe the embodiment of the third scheme of the application in detail, the advantage of this scheme is:

(1) adopt the connectionless mode of RNA between Home eNodeB and Home eNodeB, to transmit RNSAP message, do not need to distribute for it special Context identifier, save Context identifier resource;
