Tracing section updating process provided in the embodiment of the present invention is carried out below by way of several specific embodiments detailed
Explanation.
First specific embodiment, during UE is in Idle state and the TAU that SGW changes occurs, SGW-C is not sent out to SGW-U
Send configuration signal.
In the specific embodiment, SGW-C receives the Create Session Request message that MME is sent, and is disappeared according to this
The eNB TEID in operation instruction (Operation Indication) and Bearer Context IE carried in breath is determined
The TAU process that SGW changes occurs, then SGW-C only creates relevant bearer context, does not send SGW user plane functions to SGW-U
Configuration signal.It is specific as shown in Figure 5:
Step 501:UE initiates TAU process, sends TAU request to MME；
Step 502:MME has sent Create Session Request message to SGW-C；
Step 503:SGW-C checks whether the Bearer Context IE from the message that MME is received carries operation instruction
(Operational Indication) and S1-U eNB TEID, if carrying Operation indication but not taking
Band S1-U eNB TEID, then SGW-C judges that the process for TAU process, and executes step 504；
Step 504:SGW-C allocation of downlink S5/S8SGW TEID, and send modification carrying request (Modify Bearer
Request) message carries downlink S5/ in the modification bearing request message to PGW control plane functional entity (abbreviation PGW-C)
S8SGW TEID；
Step 505:PGW-C receives Modify Bearer Request message, completes downlink bearing and updates, and to SGW-C
Returning response (Response) message；
Step 506:SGW-C saves user plane bearer context, but the configuration of SGW user plane functions is not issued to SGW-U
Signaling, and creation conversational response is sent to MME, MME completes the follow-up process of TAU according to the creation conversational response.
Second specific implementation carries the TAU (TAU with active flag) or service request of activation mark
During (Service Request), SGW-C sends the configuration signal of SGW user plane functions to SGW-U.
In the specific embodiment, when SGW-C receives the Modify Bearer Request message that MME is sent, according to message
In Bearer Context IE in eNB TEID, determine that UE or network will carry out data transmission, therefore SGW-C needs basis
The bearer context of preservation sends the configuration signal of SGW user plane functions to SGW-U, routed with updating SGW user face data/
Tunnel is transmitted in forward rule, configuration user face.It is specific as shown in Figure 6:
TAU with active flag or service the request process that step 601:UE is initiated；
Step 602:MME request eNB establishes empty port load-supporting, and after the completion of empty port load-supporting is established, MME obtains the S1- that eNB is sent
U eNB TEID；
Step 603:MME sends Modify Bearer Request to SGW-C or modification access bearer requests (Modify
Access Bearers Request) message, the Modify Bearer Request or modification access bearer request in carry
S1-U eNB TEID；
Step 604:SGW-C determines Modify Bearer Request or Modify Access Bearers Request
S1-U eNB TEID is carried in Bearer Context IE in message, it is determined that UE or network needs carry out data transmission,
Therefore the user plane functions of SGW will be configured；
Step 605:SGW-C is distributed and is saved uplink S1-U SGW TEID, then returns to modification carrying response to MME
(Modify Bearer Response) or modification access bearer response (Modify Access Bearers Response) disappear
Uplink S1-U SGW TEID is carried in breath, modification carrying response or modification access bearer response；
Step 606:SGW-C checks the user plane bearer context saved, and acquisition is all not to carry out holding for user face configuration
Context is carried, and generates the configuration signal of SGW user plane functions according to the bearer context of acquisition, by the SGW user plane functions
Configuration signal be sent to SGW-U so that SGW-U complete the configuration of user face data routing/forward rule.
Third specific embodiment, the session (Paging) of downlink data triggering.
In the specific embodiment, before SGW-C carries out the configuration of user face to SGW-U, SGW-U may will receive PGW use
Downlink data packet that family face functional entity (abbreviation PGW-U) is sent and can not route, SGW-U needs to cache the downlink first at this time
Then data packet parses the packet header GTP-U of the downlink data packet, and sends SGW-C for the packet header GTP-U.SGW-C is according to this
The S5/S8 SGW TEID in the packet header GTP-U carries out bearer context mapping, if corresponding EPS carrying can be found, sends out to MME
Downlink data notification (Downlink Data Notification, DDN) message trigger paging is sent, SGW-U is otherwise configured and loses
Abandon the data packet.It is specific as shown in Figure 7:
Step 701:PGW-U sends downlink data packet to SGW-U；
Step 702:SGW-U caches the downlink data packet, regular if there are the processing of the downlink data packet on SGW-U,
But there is no downlink S1-U eNB TEID, then SGW-C is requested to trigger DDN process；If without the downlink data packet on SGW-U
Processing rule, then SGW-U parses the packet header GTP-U of the downlink data packet, then sends SGW-C for the GTP-U header packet information,
And execute step 703；
Step 703:SGW-C matches the carrying of preservation or more according to the GTP-U header packet information of the downlink data packet received
Text executes option A if finding the bearer context to match: triggering DDN process, and executes the service request of network-triggered
Process；Otherwise, SGW-C, which is determined, abandons the downlink data packet, and executes option B: generating the configuration of corresponding SGW user plane functions
Signaling is sent to SGW-U, so that SGW-U completes the configuration of user face data routing/forward rule, configuration SGW-U, which is abandoned, to be received
All data packets received by the carrying of the downlink data packet.
