It should be related to；
Optionally, if the multiple and different outer data network of same UE access, UE corresponds to multiple and different at this time
APN, in order to distinguish corresponding first parameter of different APN, when first network equipment receives the corresponding attachment of the first request message please
After asking, the correspondence of the first parameter, UE and APN between any two can be stored.
It should be noted that first threshold can voluntarily be set by network operator.The signaling processing of first parameter instruction is excellent
First grade is lower, shows that the importance of APN corresponding with the signaling processing priority is lower, therefore, in order to not influence weight as possible
APN is wanted to alleviate congestion under the premise of corresponding to the processing of signaling, the corresponding UE access controls of the low APN of the importance can be refused
Face, alternatively, first network equipment delays timer, and indicate that UE is sent out after timer expiry is delayed, then again to UE transmissions
Send the first request message.If the signaling priority of the first parameter instruction is greater than or equal to first threshold, according to the first ginseng

Parameter is 008, then delays to handle tracing section updating request flow and the control plane data transmission that UE corresponding with the 2nd APN is initiated
Flow, normal other signaling processes for handling the corresponding UE of the 2nd APN and initiating.
It should be noted that the priority height for the different signaling processes that same UE is initiated may be opposite.For example, first
The importance of the corresponding APN of UE is high, then first network equipment answers the signaling that the first UE of priority processing is sent, but due to the first UE pairs
The importance of the APN answered is high, in order to avoid first network equipment omits the signaling of processing the first UE transmissions, when the first UE initiations are gone
During attachment flow, it should delay to handle above-mentioned attachment removal flow, to delay to disconnect the connection between the first UE and first network equipment,
That is, the relatively low priority of attachment removal flow setting initiated for the first UE.For another example the weight of the corresponding APN of the 2nd UE
The property wanted is low, then first network equipment should delay to handle the signaling that the 2nd UE is sent, but due to the importance of the corresponding APN of the 2nd UE
It is low, in order to mitigate the processing load of first network equipment, when second network equipment initiates attachment removal flow, should handle as early as possible
Attachment removal flow is stated, so that the first UE disconnects the connection between first network equipment as early as possible, that is to say, that initiate for the 2nd UE
The higher priority of attachment removal flow setting.Operator can voluntarily set APN pairs according to the height of UE corresponding A PN importance
The first parameter and the second parameter answered, details are not described herein.
It should be noted that the first solicited message includes the corresponding user informations of UE, first network equipment storage user
The corresponding pass of correspondence or user information with the first parameter, the second parameter between any two between information and the first parameter
System.Due to all including the user information in the signaling transmitted by UE, and the corresponding user informations of difference UE are different, therefore, first
The network equipment can identify UE according to the user information in signaling, and find the first parameter corresponding with UE or the first ginseng
Number and the second parameter, and the signaling sent according to the instruction of the first parameter or the first parameter and the second parameter, processing UE.
If step 204, UE or control plane initiate attachment removal flow, first network equipment is sent to second network equipment
Delete conversation request message.
UE can actively initiate attachment removal flow or initiate attachment removal flow by control plane.Optionally, UE is actively initiated
During attachment removal flow, UE sends attachment removal request message to first network equipment, in response to attachment removal request message, first network
Equipment sends to second network equipment and deletes conversation request message.Optionally, if UE is not sent out for a long time to first network equipment
Deliver letters order or UE for a long time do not respond first network equipment transmission signaling, then may UE because failure and other reasons disconnect and control
Attachment removal flow is then actively initiated in the connection in face processed by control plane, is such as actively sent out from first network equipment to second network equipment
