Please further consulting Fig. 4, is another flow chart of embodiment of the invention paging processing method.User terminal is to be in Idle state among this embodiment, and network side receives the downlink data about this user terminal, need this user terminal be activated to operating conditions from Idle state by paging.
As shown in Figure 4, comprise step:
P-GW receives the downlink data about user terminal, and P-GW searches the session information that this user terminal is associated by the purpose IP address of downlink data in database, comprise some user profile.If finding the carrying of this user terminal is based upon on this P-GW, the information that can obtain being correlated with then, wherein comprise the international mobile subscriber identity that user terminal identification for example is a user terminal (IMSI, International Mobile Subscriber Identity), S-GW sign (ID) and MME sign (ID) at least.Suppose that the S-GW sign is corresponding S-GW1.
This step P-GW determines the S-GW that this sign is corresponding according to the S-GW sign of obtaining, and also promptly determines purpose S-GW.
In normal paging flow process, P-GW need send to purpose S-GW with downlink data in the normal loading end GTPU tunnel of user terminal be S-GW1.Be directly downlink data to be sent to purpose S-GW in the prior art, if purpose S-GW is in malfunction, then can't receive downlink data, also just can't finish the paging flow process, the business that causes network side to be initiated can't insert.The embodiment of the invention is a paging failure phenomenon of avoiding this situation to cause, can be periodically each S-GW of the resource pool under the purpose S-GW be carried out fault condition detection, thereby know the state of each S-GW, just can know also whether purpose S-GW is malfunction, thereby carry out respective handling.The cycle of described fault condition detection can be provided with as required.
Whether can adopt existing node failure detection method to detect S-GW among the present disclosure embodiment breaks down.For example adopt two-way forwarding to detect the detection method of (BFD, Bidirectional Forwarding Detection) method and various other protocol hierarchies.BFD is a kind of simple " Hello " agreement, by on the session channel of being set up between two network entities, periodically sending detection messages to the opposite end, if one of them network entity is not received the detection messages of opposite end in the time of setting, think that then fault has taken place certain part in this duplex channel, or think that fault has taken place in the opposite end.
P-GW is according to the testing result of each S-GW of the resource pool under the purpose S-GW being carried out fault condition detection in this step, judge whether purpose S-GW is malfunction, if, show that downlink data can't send to purpose S-GW, then entering step 404 handles, if not, show that downlink data can send to purpose S-GW smoothly, enter step 409 and handle.
In this step, P-GW can be known the S-GW that is in normal condition according to testing result, select the S-GW of a S-GW arbitrarily from these S-GW that are in normal condition as service, be used for substituting the S-GW1 that breaks down, hypothesis is to select S-GW2 to substitute the S-GW of S-GW1 as service in the present embodiment.
Because that select is S-GW2,, wherein comprise the IMSI and the MME sign of user terminal at least so P-GW sends the downlink data that comprises relevant information to selected S-GW2.
The downlink data that step 406, selected S-GW receive the P-GW transmission carries out buffer memory, identifies pairing MME to MME and sends downlink data notification message, notifies this MME to trigger the paging flow process;
The downlink data that S-GW2 receives the P-GW transmission carries out buffer memory, send downlink data notification message (for example Downlink data notification message) to the pairing MME of MME sign ID, wherein carry user terminal identification, notify the paging flow process of this MME triggering the pairing user terminal of described terminal iidentification.
In this step, the former purpose S-GW sign that has broken down in the mobile management context of the user terminal that MME need preserve it makes new S-GW2 sign into, and initiates the paging flow journey.
The paging flow process is as follows: MME determines eNB according to the eNB tabulation that the mobile management context of user terminal is preserved, and sends paging request message (for example Paging request) to this eNB, and is transmitted to user terminal by eNB.User terminal can send page-response message (for example Paging response) and give eNB after receiving paging request message, and is transmitted to MME by eNB.
MME receives the page response that returns, and the S-GW that sends downlink data notification message before selecting also is that the S-GW2 of current service rebuilds bearer context, and makes corresponding session updates.
The downlink data that step 409, purpose S-GW receive the P-GW transmission carries out buffer memory, identifies pairing MME to MME and sends downlink data notification message, notifies this MME to trigger the paging flow process, enters step 410;
Purpose S-GW is S-GW1, the downlink data that S-GW1 receives the P-GW transmission carries out buffer memory, identify pairing MME to MME and send downlink data notification message, wherein carry user terminal identification, notify the paging flow process of this MME triggering the pairing user terminal of described terminal iidentification.
The paging flow process is as follows: MME determines eNB according to the eNB tabulation that the mobile management context of user terminal is preserved, and sends paging request message (for example Paging request) to this eNB, and is transmitted to user terminal by eNB.User terminal can send page-response message (for example Paging response) and give eNB after receiving paging request message, and is transmitted to MME by eNB.
MME receives the page response that returns, and the S-GW that sends downlink data notification message before selecting also is that the S-GW1 of current service rebuilds bearer context, and makes corresponding session updates.
Need to prove, for the user terminal that does not have downlink data,, can be to wait for initiating periodically Routing Area Update (TAU if S-GW breaks down, when Tracking Area Update) asking, select a normal S-GW to carry out bearer context by MME and rebuild.
Can find, the embodiment of the invention is by before the downlink data that sends to service gateway entity about user terminal, whether judge earlier provides the service gateway entity of service to break down, if select a service gateway entity to substitute the described service gateway entity that breaks down in the service gateway entity that does not break down the resource pool under this service gateway entity and described downlink data carried out buffer memory and notify the paging of mobile management network element triggering to described user terminal.In this way, solved effectively under the resource pool framework, the network element S-GW of core net breaks down when switching, the problem that the network side paging business can't continue to finish, the mode that drives by customer service is carried the session reconstruction step by step simultaneously, avoid the short time internal fault to recover the impact that brings to network, can not cause losing of customer service again.Therefore the embodiment of the invention provides a kind of paging processing method under the situation that service gateway entity breaks down, and makes the business of network side to insert, and paging can be finished, perfect existing paging flow process.
