ETSI ETSI TS 103 202-2 V1.1.1 (2015-12)9 4.2 Network or Bearer modification procedure as per Figure 19, from step 2 to 11, or as per Figure 20, from step 2 to 9; or Dedicated bearer deactivation procedure as per Figure 14, from st

28、ep 2 to 9. Comments: Messages 1, 2, and 5 are common for architecture variants with GTP-based S5/S8 and PMIP-based S5/S8. The messages identified as (A) differ in the case that PMIP-based S5/S8 is employed and is defined in ETSI TS 123 402 9. The Bearer Resource Command Procedure allows the UE to re

29、quest for a modification of bearer resources (e.g. allocation or release of resources) for one traffic flow aggregate with a specific QoS demand. Alternatively, the procedure allows the UE to request for the modification of the packet filters used for an active traffic flow aggregate, without changi

30、ng QoS. If accepted by the network, the request invokes either the Dedicated Bearer Activation Procedure, the Bearer Modification Procedure or a dedicated bearer is deactivated using the PDN-GW Initiated Bearer Deactivation Procedure. The deactivation procedure is used by the UE when the UE already

31、has a PDN connection with the PDN-GW. A UE can send a subsequent Request Bearer Resource Modification Message before the previous procedure is completed. ETSI ETSI TS 103 202-2 V1.1.1 (2015-12)17 5.2.3.4 Bearer Resource Failure Indication Procedure TP_TM_04 Standards Reference: ETSI TS 129 274 1, cl

32、ause 7.2.6 PICS item: Summary: Bearer Resource Failure Indication Procedure. Test purpose: A Bearer Resource Failure Indication shall be sent by the PDN-GW to an S-GW and forwarded to the MME to indicate failure of the UE requested bearer resource allocation procedure or UE requested bearer resource

33、 modification procedure. Test Procedure: 1) CORE, RAN, and one UE available. A simulation platform may be necessary to emulate the PDN-GW. 2) MME is configured with the GTP Tunnel Parameter. 3) S-GW is configured with the GTP Tunnel Parameter. 4) Verify IP connectivity between the two nodes. 5) The

34、resources or the memory in the PDN-GW are limited via the OAM interface in order to trigger the Bearer Resource Failure Indication. 6) Attach the UE. 7) The user changes the application being used on the UE. For example, the user changes the application being used on the UE from web browsing to FTP.

35、 Expected Results: 1) Verify that the MME sends a Bearer Resource Command to the S-GW. S-GW sends it to the PDN-GW (Simulation tool). 2) Verify that the PDN-GW sends back the Bearer Resource Failure Indication with cause value. 3) Verify that the S-GW sends the Bearer Resource Failure Indication to

36、the MME. Expected Message Flow: MME BEARER RESOURCE COMMAND S-GW BEARER RESOURCE FAILURE INDICATION Comments: Using an actual S-GW, the PDN-GW should be configured through the OAM interface to force it to send back a cause value of “No resources available“ or “No memory available“. Possible cause va

37、lues are: - “No resources available“. - “No memory available“. - “User authentication failed“. - “System failure“. - “Semantic error in the TAD operation“. - “Syntactic error in the TAD operation“. - “Semantic errors in packet filter(s)“. - “Syntactic errors in packet filter(s)“. - “Mandatory IE inc

38、orrect“. - “Mandatory IE missing“. - “Conditional IE missing“. - “Invalid message format“. - “Collision with network initiated request“. - “Invalid length“. - “Service denied“. If the requested QoS is not granted (i.e. the requested QoS cannot be accepted or resources could not be allocated) the PDN

39、-GW sends a Bearer Resource Failure Indication (with a cause indicating the reason why the request failed or was rejected) message, which is delivered to the UE.

Test purpose: Check the exchange of Delete Session Request/Response after NAS Detach Request. Test Procedure: 1) EPC, RAN, and one UE is required. 2) MME is configured with GTP Tunnel Paramete

41、r. 3) S-GW is configured with the GTP Tunnel Parameter. 4) Verify IP connectivity between the two nodes. 5) UE attaches to network. 6) Switch off the UE to trigger the Detach procedure. Expected Results: 1) Verify that the MME sends the Delete Session Request to the S-GW. 2) Verify that the S-GW for

42、wards the Delete Session Request to the PDN-GW. 3) Verify that the PDN-GW sends back the Delete Session Response. 4) Verify that the S-GW sends the Delete Session Response to the MME. Possible cause values in the Delete Session Response are: - “Request accepted“. - “Context not found“. - “Mandatory

43、IE incorrect“. - “Conditional IE missing“. - “Invalid message format“. - “Unexpected repeated IE“. The cause value is used to inform the MME about the status of the Detach procedure.

Only if the UE is on the MME will send the Detach Accept message in response to the Detach Request message.
