Step 1104, local access network are closed according to the bearer types indication of creating in carrying request or the PDP activation request and are judged that this bearer types is local connection, and local access network closes the bearer types information of preserving.
Step 1105, if there is the rear end network element, then local access network closes and also bearer types is notified to the rear end network element; Promptly close in the request send to the rear end network element or the notification message and comprise the bearer types indication at local access network;
The rear end network element can but be not limited to comprise informing charging gateway and/or policy decision entity.
Step 1106, rear end network element return to local access network and close response, and local access network closes and returns to that SGSN creates the carrying response or PDP activates response.SGSN carries out the remaining step of PDP activation process.This process is as well known to those skilled in the art, does not do here and gives unnecessary details.
Figure 12 is bearing modification or discharges in the flow process, the execution mode of notice bearer types.Present embodiment goes for the situation that LTE inserts or UTRAN/GERAN inserts, and inserts for LTE, and base station from home/base station is HeNB/eNB, and mobile management unit is MME.Insert for UTRAN/GERAN, base station from home/base station is HNB/RNC, and mobile management unit is SGSN.
In this flow process if the base station from home scene describes with the network architecture that does not have home base-station gateway.There are the scene of home base-station gateway, all message that between mobile management unit and base station from home, send all to need to transmit for the base station from home system through home base-station gateway.For the situation that UE inserts from the base station, all message directly send to the base station from mobile management unit.
Step 1201, terminal is initiated bearing modification/release or PDP modification/release flow process, connects so that modification/release is local.This non-access layer information brings mobile management unit via base station from home and home base-station gateway.
When SGSN is when linking to each other with S-GW, transmission be bearing modification/release request, when SGSN is when linking to each other with GGSN, transmission be that PDP modification/release is asked.
If bearing modification/release or PDP modification/dispose procedure are initiated by terminal, then this step needs to carry out, otherwise direct execution in step 1202.
Step 1202, mobile management unit are judged need make amendment carrying or releasing bearing (or revise or discharge PDN and connect, or revise or discharge PDP Context).
This process also might be triggered by the insertion subscription data that HSS initiates, and the variation of subscription data may cause local the connection to be modified/to discharge.The process of follow-up execution is consistent.
Step 1203, if carry out the modification of bearer types, mobile management unit closes to send to local access network revises bearing request message, wherein carries amended bearer types indication;
If releasing bearing, mobile management unit closes to local access network and sends the releasing bearing request message.
If there are gateway in mobile management unit and local access network between closing, then above-mentioned modification/releasing bearing message is transmitted through gateway, also needs to comprise the bearer types indication in the modification bearing request message of forwarding.The effect of this message is to create carrying, and specific implementation can realize with different messages.
Step 1204, local access network are preserved amended bearer types after closing and receiving the modification bearing request message;
After local access network closes and receives the releasing bearing request message, discharge local bearer context information of preserving.
Step 1205, if there is the rear end network element, then when revising carrying, local access network closes and also amended bearer types is notified to the rear end network element, promptly closes in the request that sends to the rear end network element or the notification message at local access network to comprise the bearer types indication; When releasing bearing, local access network closes notice rear end network element releasing bearing.
The rear end network element can but be not limited to comprise informing charging gateway and/or policy decision entity.
Step 1206, rear end network element return to local access network and close response, and local access network closes and returns to the response of mobile management unit modification/releasing bearing.Mobile management unit is carried out the remaining step of PDP activation process.This process is as well known to those skilled in the art, does not do here and gives unnecessary details.
Figure 13 is that LTE inserts down, and local access network closes the execution mode one that obtains bearer types.This execution mode does not limit base station type, promptly can be base station from home or ordinary base station.Being example with the ordinary base station during flow process is described, is identical to the influence of base station from home.If then also may there be home base-station gateway in base station from home, this network element does not have influence to the present invention, does not do special description.
Local access network closes and to be positioned between base station (or base station from home) and the mobile management unit in this framework, knows the bearer types of setting up carrying by monitoring or intercept and capture the message that comprises the bearer types indication that mobile management unit is sent to the base station or is sent to base station from home.
Step 1301, UE initiates service request, and the request flow process is perhaps adhered in perhaps tracing section updating request, perhaps the switching flow of source eNB initiation.Said process can trigger mobile management unit and rebulid radio bearer.
Step 1302 is initiated service request if this flow process is UE, and the request flow process is perhaps adhered in perhaps tracing section updating request, and then mobile management unit sends the initial context request to the base station, wherein comprises the bearer types indication.
If in the switching flow, variation has taken place in mobile management unit, then refers to target mobile management unit and target BS in the present embodiment, and promptly the target mobile management unit sends handoff request message to target BS, wherein comprises the bearer types indication.
