On the other hand, if the UE initiation packet data network (packet data network, referred to as PDN) of normal attachment removes connection procedure, and this PDN to connect be UE when being connected with last PDN of network, network will attachment removal UE.But, activate the carrying of urgency traffic and all non-emergent service bearers of deexcitation go in connection procedure, owing to now also having the existence of urgency traffic carrying, network can not attachment removal UE but still keep connection status.
Above-mentioned two kinds of scenes are all the networks that UE normally adheres to, but all only have urgency traffic bearer connection and do not have non-emergent EPS bearer connection.
It is after urgency traffic terminates, do not allow UE get back to attachment removal state at once that the terminal designing emergency attached state in agreement can reach the timer object identical with the value of T3412 timer, but allow UE get back to IDLE state a period of time, and within a period of time, keep the urgency traffic bearer connection of network side, if during this period of time there is the called or UE of urgency traffic will initiate urgency traffic at this, just can connects fast and not need to perform urgent PDN connection establishment process.In addition, due to urgency traffic resource-constrained, so in order to prevent urgency traffic resource long-term from being taken by a certain UE, by attachment removal UE after terminal can reach timer and T3412 timer expiry.
In the present invention, when UE normally adheres to and there is urgency traffic bearer connection, in order to reduce the waste of urgent resource, when the timer times out afterwards will attachment removal timer immediately, perform the operation being similar to emergency attached UE.The terminal that MME place safeguards can reach timer to be needed to modify along with the change of UE bearer connection.
Specifically, when the UE of normal attachment is only left urgency traffic bearer connection, the value that terminal can be reached timer by MME is revised as the value identical with T3412 timer.
On the other hand, in normal attachment and the UE that have activated urgency traffic carrying moves to a certain restricted cell time, the value that after all non-emergent service bearers of MME deexcitation, terminal can be reached timer is revised as the value identical with T3412 timer.
On the other hand, when UE normally adheres to and have activated urgency traffic bearer connection, when UE request or all non-emergent service bearers of network deexcitation connect and only remain urgency traffic bearer connection, the value that terminal can be reached timer by MME is revised as the value identical with T3412 timer.
In addition, connect if only have the UE of urgency traffic bearer connection to establish again new non-emergent service bearer, then the value that terminal can be reached timer by MME is revised as the value (be in default situations 4 minute) longer than T3412 timer.
Therefore, in these situations above-mentioned, as the UE of emergency attached, after timer T3412 and terminal can reach timer expiry, UE and MME be local attachment removal UE respectively.
