Describe the solution of the present invention in detail below in conjunction with specific embodiment.
Embodiment one
As shown in Figure 3, be the schematic diagram based on the data transmission method of Femto in the embodiment of the present invention one, described method specifically comprises the following steps:
Whether step 101:Femto gateway judgement is connected with IuH interface between the Femto base station interrupts, if execution in step 102; If not, continue the IuH interface is connected and whether interrupt judging.
Whether the IuH interface connects and to interrupt referring to: the IuH interface between Femto gateway and Femto base station whether the chain of command signaling appears extremely and the situation of user's face disconnecting.
In the Femto system, the chain of command signaling that is used for foundation, maintenance and the release of control call flow is by service quality (Quality of Service, QoS) the relatively poor IP network of protection is transmitted, and tends to occur the situation such as chain of command signaling loss and to cause the chain of command signaling to occur abnormal.Occur when abnormal in the chain of command signaling, because the transfer of data of chain of command and user's face is separate, therefore the connection of user's face not necessarily can interrupt.Therefore, judge that in this step 101 the IuH interface connects when whether interrupting, and can have following two kinds of judgment modes:
The first judgment mode: first judge the chain of command signaling and whether occur extremely, if, further user's face is connected and whether interrupt judging, if connecting, user's face do not occur extremely, can notify the Femto base station to re-register the gateway to Femto, so that the recovery of chain of command signalling is normally, if connecting, user's face also occurs extremely, definite IuH interface connection is interrupted.
The second judgment mode: the interruption because user's face connects, must mean that the chain of command signaling has occurred extremely, therefore can whether the chain of command signaling not judged extremely, but judge directly whether the connection of user's face is interrupted.
The below is take above-mentioned the first judgment mode as example.The specific implementation that this step 101 is described is:
The first step: consult test pack between Femto gateway and Femto base station and send the cycle, the Femto base station sends test pack according to the transmission cycle of consulting to the Femto gateway, and the Femto gateway returns to the Femto base station and replys bag when receiving this test pack.
HNBAP agreement and the RUA agreement used due to the chain of command signaling are carried on SCTP, therefore the reply bag that the packet that the Femto base station periodically sends to the Femto gateway and Femto gateway return to the Femto base station can be based on the packet of SCTP, certainly, the present embodiment also is not limited to the test pack of other agreements and replys bag.
Second step: the judgement of Femto gateway sets first the test pack that whether receives Femto base station transmission in duration, if not, represents that the chain of command signaling occurs abnormal, carries out for the 3rd step; If the chain of command signaling that shows the IuH interface between Femto gateway and Femto base station does not occur abnormal, therefore, user's face of IuH interface also is in connection status, continues the test pack that whether receives from the Femto base station is judged.
In this step, the Femto gateway determines according to the test pack of Femto base station transmission whether current chain of command signaling is abnormal, corresponding, and whether Femto also can return to reply to wrap according to the Femto gateway in the base station and determine whether current chain of command signaling is abnormal.
More preferably, this step also is not limited to be sent to the Femto base station by the Femto gateway test pack, and wraps to determine according to whether receiving the reply of the Femto base station returning whether current chain of command signaling is abnormal.
because the Femto base station is periodically to send test pack to the Femto gateway, therefore, the Femto gateway should be a transmission cycle in the time interval of twice adjacent reception test pack, if it is congested that current network occurs, the Femto base station possibly can't arrive to the test pack that the Femto gateway sends on time, therefore, can be the Femto gateway and set one first setting duration, begin timing upper after once receiving test pack at the Femto gateway, if set in duration first and receive test pack, the congestion state of determining current network is in tolerable scope, if set in duration first and do not receive test pack, determine that current chain of command signaling occurs abnormal.
Described first sets duration can be a transmission cycle, also can be set to the length greater than a transmission cycle, considers the propagation delay time that the Femto gateway can be tolerated, this first length of setting duration can be set to less than the transmission cycle situation of 2 times.
The 3rd step: whether the Femto gateway judges the data traffic of local user's face less than the first threshold of setting, if less than the first threshold of setting, determines that user's face of IuH interface interrupts, and can determine IuH interface disconnecting, execution in step 102 this moment; If be not less than first threshold, user's face of determining the IuH interface is in connection status, this moment, the IuH interface connected not interruption, can continue to carry out transfer of data by user's face connection of IuH interface, but because the chain of command signaling of IuH interface occurs abnormal, therefore the Femto base station need to re-register the gateway to Femto, can carry out the continuation transmission of user face data after the success of re-injection volume.
In this step, the Femto gateway can carry out traffic monitoring to the port that user plane data transfer is carried out in this locality, and whether the data traffic of test local user face is less than the first threshold of setting.
User's face resource in the CS territory between step 102:Femto gateway buffer memory and this Femto base station and PS territory.
When user's face resource of described buffer memory is IuH interface disconnecting, between Femto gateway and Femto base station the IuH interface user plane be connected the resource using and produce, as information such as: the log-on message of UE, UEContext ID, UE contextual information (control information of HNBAP, RUA, RANAP and parameter) and CS/PS territory records.
The successfully registration in the Femto gateway again of step 103:Femto base station.
In this step 103, the Femto base station sends test pack to the Femto gateway, and judgement sets in duration whether receive the reply bag that the Femto gateway returns second, if receive, shows that the chain of command signaling connects not abnormal; If do not receive, whether pass through to detect the data traffic of local user's face less than the Second Threshold of setting, further judge with the Femto gateway between user's face of IuH interface be connected and whether interrupt, if less than the Second Threshold of setting, think user's face disconnecting of IuH interface, at this moment, the Femto base station determine and the Femto gateway between the disconnecting of IuH interface, again register in the Femto gateway.
The first threshold that relates in described Second Threshold and step 101 can be identical numerical value, also can determine respectively the monitor value of data flow according to Femto base station and Femto gateway.
After this, the Femto base station can initiatively be attempted setting up SCTP with the Femto gateway and is connected, and again initiates login request message to the Femto gateway, after the Femto gateway receives the registration request of Femto base station, carry out the base station login operation, complete the registration of Femto base station in the Femto gateway.
In the scheme of the present embodiment, because user's face resource of Femto gateway buffer memory has certain ageing, if the Femto base station heavily is not registered to the Femto gateway for a long time, within the time that this section grown, variation may all occur in network environment and user terminal, and user's face that user's face resource of Femto gateway buffer memory can not satisfy actual IuH interface connects.Therefore, after Femto gateway cache user face resource, this Femto base station need to heavily be registered to Femto gateway and then execution in step 104 in the thresholding duration.
Step 104:Femto gateway utilizes the transfer of data in described user's face resource recovery CS territory and the PS territory of buffer memory.
Concrete, the Femto gateway utilizes described user's face resource recovery CS territory of buffer memory and the transfer of data in PS territory to comprise:
The first step, the Femto gateway sends to described Femto base station with described user's face resource, is connected with the user's face that recovers the IuH interface between the Femto base station.
Second step utilizes user's face of IuH interface to connect to carry out the transfer of data in CS territory and PS territory.
Through above-mentioned steps 101～step 104, the user face data of Femto base station and Femto gateway continues normal transmission.
