53rd, the user equipment according to any one of claim 48-50, it is characterized in that, the transmitter, it is additionally operable to before the receiver receives the access-reject message from first core net node, the version information of the user equipment is sent to first core net node by access network node, so that first core net node is worth code the reason for determining access request of the first cause value code to refuse the user equipment according to the version information, and the duration of the timer is set.

54th, the user equipment according to any one of claim 48,49 or 51, it is characterized in that, the receiver, it is additionally operable to before the access-reject message from first core net node is received, the RRC connection reconfiguration requests from access network node are received, the RRC connections reconfiguration request sets up what is sent after context request receiving the initialization from first core net node for the access network node；

The transmitter, the RRC connections for being additionally operable to send the version information comprising the user equipment reconfigure response to the access network node, so that context response is set up in the initialization of the version information of the access network node generation comprising the user equipment, and context response is set up in the initialization of the version information comprising the user equipment described in sending, and then The reason for making first core net node determine access request of the first cause value code to refuse the user equipment according to the version information is worth code, and sets the duration of the timer.

55th, the user equipment according to any one of claim 48-50, it is characterized in that, the transmitter, it is additionally operable to before the access request message to first core net node is sent, sends service request information or PDP activates request message to first core net node；

The receiver, it is additionally operable to receive the P-TMSI reassignment orders from first core net node, the P-TMSI is reassigned in order and is carried RAI, it is first core net node after the service request information or PDP activation request messages that the transmitter sends is received that the P-TMSI, which reassigns order, determines what is sent during at least one node overload in the core net；

The receiver, is additionally operable to receive the RAI from system broadcasts;

The processor, is additionally operable to contrast the RAI that the RAI carried in the P-TMSI reassignment orders that the receiver is received is received from the system broadcasts with the receiver;The transmitter, if being additionally operable to processor contrast to obtain the P-TMSI to reassign the RAI carried in order different from the RAI that the receiver is received from the system broadcasts, the routing update request message is sent to first core net node.

56th, the user equipment according to any one of claim 48,49 or 51, it is characterized in that, the transmitter, it is additionally operable to before the access request message to first core net node is sent, sends service request information or PDN connection request messages to first core net node；

The receiver, it is additionally operable to receive the GUTI reassignment orders from first core net node, the GUTI, which is reassigned, carries TAI lists in order, it is first core net node after the service request information or the PDN connection request messages that the transmitter sends is received that the GUTI, which reassigns order, determines what is sent during at least one node overload in the core net；

The receiver, is additionally operable to receive the TAI from system broadcasts;

The processor, is additionally operable to judge in the TAI lists that the receiver is received Whether the TAI of the system broadcasts is received from comprising the receiver;

The transmitter, judges to obtain not including the TAI that the receiver is received from the system broadcasts in the TAI lists, sends the tracing section updating request message to first core net node if being additionally operable to the processor.

57th, the user equipment according to any one of claim 48-51, it is characterized in that, the transmitter, is additionally operable to before the access request message to first core net node is sent, and sends service request information to first core net node；

The receiver, it is additionally operable to receive the Service Reject message from first core net node, the second cause value code is included in the Service Reject message, the reason for service request for the refusal user equipment that the second cause value code determines for first core net node according to the version information, is worth code, the Service Reject message be first core net node after the service request information that the transmitter is sent is received, determine what is sent during at least one node overload in the core net；

The transmitter, second cause value code for being additionally operable to be received according to the receiver sends the Attach Request message to first core net node.
