In this step, terminal also can need to be set up new Packet data service carrying because of it, maybe need to revise QoS or the TFT in its Packet data service carrying, maybe need to discharge the reasons such as Packet data service carrying, according to concrete reason, send PDN connection request, bearing resource distributes request, bearing resource revises request or PDN connects the request of disconnection to network, network determines that need to initiate default packet data service bearer context activates after receiving request, packet dedicated data service bearer context activates, Packet data service bearer context is revised, or Packet data service bearer context deexcitation, and then triggering Packet data service bearer context update request signaling message, initiation packet data service bearer context renewal process, here, network also can be refused the various requests of terminal as the case may be, for example, receive to send PDN connection request after the PDN connection request that terminal sends and, to terminal, but the situation of this refusal is not the present invention, do not pay close attention to according to signaling message absolutely, repeats no more.
In this step, Packet data service bearer context update request signaling message should comprise protocol type information unit, EPS bearing identification information unit, three of message type information unit basic information unit (BIU), wherein protocol type information unit is used to indicate the communication protocol type that this message relates to, the Packet data service bearing identification that EPS bearing identification unit adopts while being used to indicate flow of transmitted information between terminal and network, message type information unit is used to indicate the type of this message, concrete type of message can be that default packet data service bearer context activates, packet dedicated data service bearer context activates, revise Packet data service bearer context or the deexcitation of Packet data service bearer context., according to the difference of its bearer context, change meanwhile, can also comprise the message content information unit that transmits relevant concrete message content, for transmitting the information such as bearer context after change.Generally, network also should be told its APN of terminal (Access point name, APN) and PDN address corresponding to APN, to set up the route between terminal and PDN.
Step 1402: whether terminal judgement accepts Packet data service bearer context is upgraded.
In this step, terminal receives Packet data service bearer context and upgrades after signaling message, according to the message content of the protocol type in signaling message, EPS bearing identification and three basic information unit (BIU)s of type of message, it is decoded and obtains corresponding concrete message content, according to the legitimacy of correlation criterion judgement Packet data service carrying, and judge whether to accept Packet data service bearer context update request according to the facilities of terminal itself.The described judgement to the decoding of signaling message and validity thereof is same as the prior art, repeats no more.If accept Packet data service bearer context update request, perform step 1403, otherwise, execution step 1405.
Step 1403: terminal is sent out the renewal of Packet data service bearer context to network and accepted signaling message.
In this step, Packet data service bearer context is accepted signaling message by sending out in terminal.If terminal determines to accept this Packet data service bearer context update request, above send out this signaling message.It need to comprise protocol type information unit, EPS bearing identification information unit, three of message type information unit basic information unit (BIU), and three basic information unit (BIU)s are herein consistent with three basic information unit (BIU) effects in step 1402, repeat no more.
Step 1404: terminal is upgraded its Packet data service bearer context.
In this step, the concrete message content that terminal issues according to network upgrades its bearer context, and in terminal, upgrades and store up-to-date Packet data service bearer context.
Step 1405: terminal is sent out Packet data service bearer context to network and upgraded rejection signaling message.
In this step, Packet data service bearer context rejection signaling message is by sending out in terminal, its message comprises following information unit: protocol type, EPS bearing identification, type of message, four basic information unit (BIU)s of Reason For Denial, message content information unit is according to the difference of its message transfer type and different or be sky in addition.Wherein protocol type, three basic information unit (BIU)s of EPS bearing identification and type of message are consistent with three basic information unit (BIU)s in step 1402, repeat no more, Reason For Denial information unit is used to indicate the unaccepted reason of Packet data service bearer context update request.Packet data service bearer context rejection signaling message is only when terminal is thought inadequate resource, TFT is asynchronous or occur that the cause determination bearer context request such as protocol error are unreasonable, or terminal determines not accept from just transmission in the situation of the Packet data service request of network side according to the configuring condition of himself.In this message, should clearly indicate Reason For Denial.
Step 1406: network based Reason For Denial is made respective handling.
In this step, network receives the Packet data service bearer context renewal rejection signaling message that terminal is sent, according to the concrete Reason For Denial indicating in Reason For Denial information unit, make again initiation packet data service bearer context update request or maintain the respective reaction such as original present situation.
