2 Overview

Since packet-switched (PS) services in Wideband Code Division Multiple Access (WCDMA)networks are booming and the High Speed Downlink Packet Access (HSDPA) and High SpeedUplink Packet Access (HSUPA) techniques are now widely applied, network operators are moreand more interested in finding more efficient ways to process PS user-plane data and reduce theuser-plane delay. One Tunnel, available since 7.2 Tunnel Management Messages in 3GPPTS29.274 V10.5.0, is ideal for addressing this issue.

The One Tunnel feature allows user-plane data to be transmitted between the RNC and GGSNthrough a single tunnel. As a result, the user-plane data does not need to go through two tunnels,which are between the RNC and the Serving GPRS Support Node (SGSN) and between theSGSN and GGSN, separately. With One Tunnel, user-plane data does not pass through the SGSNalthough control-plane data still passes through the SGSN. Figure 2-1 shows how One Tunnelworks for data transmission between the RNC and GGSN.

NOTE

In the figure, the solid blue line indicates the tunnel for user-plane data and the dotted blue lines indicatethe tunnels for control-plane data.

In UMTS and LTE (UL) interoperability scenarios, the S-GW serves as the anchor point for PSuser-plane data. By using the S12 interface introduced in 7.2 Tunnel Management Messages in3GPP TS29.274 V10.5.0, a direct tunnel for transmitting PS user-plane data can be establishedbetween the RNC and S-GW. This tunnel is referred to as S12 One Tunnel. With S12 One Tunnel,user-plane data does not pass through the SGSN although control-plane data still passes throughthe SGSN. Figure 2-2 shows how S12 One Tunnel works for data transmission between theRNC and S-GW.

Figure 2-2 Data transmission between the RNC and S-GW when S12 One Tunnel is applied

NOTE

In the figure, the solid blue lines indicate the tunnels for user-plane data and the dotted blue lines indicatethe tunnels for control-plane data.

The SGSN determines whether the One Tunnel feature is used. In addition, the SGSN checkswhether the interface is the Gn/Gp interface or the S4 interface to determine whether the datashould be sent to the S-GW or the GGSN. The GGSN sends the IP address and tunnel endpointidentifier (TEID) of the GGSN or S-GW to the RNC using the RAB Assignment Requestmessage. The RNC only needs to send the data about this service connection to the IP addressand TEID specified in the RAB Assignment Request message.

One Tunnel applies to IP over Iu-PS networking and provides the following benefits:

l Reduced capital expenditure and operating expense.

One Tunnel enables operators to reduce the expenses related to SGSN user-plane resources.



4

l Easier capacity expansion.Operators only need to expand the user-plane capacity of the RNC and GGSN or S-GW toprocess more PS traffic. In comparison with the SGSN, these devices are easier to upgradeand expand.

3 Technical Description

3.1 Working PrinciplesIn WCDMA networks, the PS user-plane data normally needs to pass through the SGSN, whichis connected to the GGSN and RNC through two separate tunnels. As the PS traffic volumegrows, the user-plane capacity of the SGSN can easily become a bottleneck for serviceprocessing. One Tunnel solves this problem by establishing a direct tunnel between the RNCand GGSN so that PS user-plane data no longer passes through the SGSN. Figure 3-1 showsOne Tunnel between the RNC and GGSN.

Figure 3-1 One Tunnel between the RNC and GGSN

NOTE

In the figure, the solid red lines indicate the tunnels for user-plane data and the dotted red lines indicatethe tunnels for control-plane data.

One Tunnel between the RNC and S-GW over the S12 interface applies to UL interoperabilityscenarios. With this feature, PS user-plane data is transmitted between the RNC and S-GW

without passing through the SGSN. As a result, the increased PS traffic volume does not imposeany burden on the SGSN.

One Tunnel complies with the GPRS Tunneling Protocol for User Plane (GTP-U). Figure 3-2and Figure 3-3 show the user-plane protocol stack for two-tunnel cases and One Tunnel,respectively.

Figure 3-2 User-plane protocol stack for two-tunnel cases

Figure 3-3 User-plane protocol stack for One Tunnel

The control-plane protocol stack is the same for both two-tunnel cases and One Tunnel. Control-plane data still passes through the SGSN.

With or without One Tunnel, the SGSN is responsible for mobility management. For example,when a UE roams to an area served by another RNC, the SGSN changes the user-plane tunnelbetween the RNC and GGSN or S-GW.

For BSC6900, the SGSNFLG parameter specifies whether to use One Tunnel. Value NOindicates One Tunnel is used and value YES indicates One Tunnel is not used.

3.2 Impact on NEs and Interfaces



7

3.2.1 Impact on the RNCIn RAN14.0, a new feature Transmission Resource Pool in RNC/BSC is available. With thisfeature, the Iu-PS interface works in either pooled mode or non-pooled mode. One Tunnel hasdifferent requirements for each of these modes:

l When Iu-PS works in non-pooled mode, an IP path between the RNC and GGSN or S-GWmust be configured, and the Ping detection function needs to be enabled on this IP path.

l When Iu-PS works in pooled mode, One Tunnel has no impact on the RNC.

When Iu-PS works in pooled mode, the Iu-PS interface boards form a pool and peer networkelements (NEs) can be connected to any of the boards in the pool. This scenario does not requireIP paths between the RNC and connected peer NEs. For more details, see the TransmissionResource Pool in RNC Feature Parameter Description.

3.2.2 Impact on the SGSN, GGSN, and S-GW

Impact on the SGSNl The SGSN configurations must support One Tunnel between the RNC and GGSN or S-

GW.l The RAB ASSIGNMENT REQUEST messages from the SGSN must carry the IP address

of the GGSN or S-GW.

Impact on the GGSNThe GGSN must support One Tunnel.

Impact on the S-GWThe S-GW must support the S12 interface.

3.2.3 Impact on InterfacesOne Tunnel affects the Iu-PS interface as follows:

l The IP address of the SGSN for user-plane data transmission in the RAB ASSIGNMENTREQUEST messages must be replaced with the IP address of the GGSN or S-GW for user-plane data transmission.

l The number of Iu-PS signaling points remains unchanged.

l Others

– The Iu-PS control-plane data must be configured.

6.4.2 Data PreparationFor Iu-PS in pooled mode, no data preparation is required.

For Iu-PS in non-pooled mode, data related to the Iu-PS adjacent node and IP path needs to beprepared.Table 6-1 and Table 6-2 list the related parameters. The GGSN is the adjacent nodefor One Tunnel between the RNC and GGSN, and the S-GW is the adjacent node for S12 OneTunnel.

In the following tables, "-" indicates that there are no special requirements for data configurationand users can configure the data as needed.

6.4.3 PrecautionsNone.

6.4.4 Feature ActivationNote that the feature activation/initial configuration for Iu-PS in pooled mode is different fromthat for Iu-PS in non-pooled mode.

NOTE

This feature cannot be configured using the CME.

Iu-PS in Non-pooled Mode

Perform the following steps to activate or initially configure One Tunnel between the RNC andGGSN:

Step 1 Run the ADD ADJNODE command to add the GGSN as the adjacent node. In this step, setparameters as follows:

l Set Adjacent Node Type to IUPS so that the node type is set to Iu PS.

l Set Transport Type to IP so that the transport type is IP.

l Set SGSN FLAG to NO. Depending on the configured adjacent node, set the parameter toGGSN or S-GW.

Step 2 Run the ADD IPPATH command to add a user-plane IP path. In this step, set thePEERIPADDR parameter to the IP address of the GGSN or S-GW.

Step 3 Optional: If layer 3 networking is deployed between the RNC and the peer node, run the MMLcommand ADD IPRT to add an IP route.

----End

NOTE

On the SGSN, GGSN, or S-GW side, you can run associated commands to check whether the feature OneTunnel is supported.

The feature activation procedure for One Tunnel between the RNC and S-GW is the same asthat for One Tunnel between the RNC and GGSN for Iu-PS in non-pooled mode. The first stepcan be skipped if the license has been activated for One Tunnel between the RNC and GGSN.This is because One Tunnel between the RNC and S-GW uses the same license as One Tunnelbetween the RNC and GGSN.



14

Iu-PS in Pooled ModeThe feature does not need to be activated.

6.4.5 Activation Observation

Iu-PS in Non-pooled ModePerform the following steps to check whether One Tunnel has been activated:

Step 1 On the LMT, start signaling tracing over the Iu interface. For details, see Tracing Messages onthe Iu Interface.

Figure 6-1 Setting Iu interface tracing

Step 2 Use a UE to start a PS service.

Step 3 In the Iu interface tracing data, check the information element transportLayerAddress in theRANAP_RAB_ASSIGNMENT_REQ message.

Figure 6-2 Iu interface tracing

Step 4 If the value of the information element transportLayerAddress is the IP address configuredfor the GGSN or S-GW during transmission resources configuration, this feature has beenactivated.

Iu-PS in Pooled Mode

Perform the following step to check whether One Tunnel has been activated:

Step 1 Run the DSP ADJNODE command and enter the adjacent node ID of the SGSN. The expectedresult is that Operation state is Available.

----End

6.4.6 DeactivationFor Iu-PS in non-pooled mode, you can also run the RMV ADJNODE command with ANI(BSC6900,BSC6910) set to the adjacent node ID of the GGSN or S-GW to deactivate OneTunnel.Example

6.4.7 Example//Activation procedure: //Adding an adjacent node ADD ADJNODE: ANI=0, NAME="S-GW NAME", NODET=IUPS, TRANST=IP, ISIPPOOL=NO, SGSNFLG=NO; /Adding an IP path for the adjacent node ADD IPPATH: ANI=0, PATHID=1, ITFT=IUPS, PATHT=BE, IPADDR="80.1.1.1", PEERIPADDR="10.161.0.1", PEERMASK="255.255.255.0", TXBW=1000, RXBW=1000; //Adding a layer 3 route to this adjacent node ADD IPRT: SRN=0, SN=14, DSTIP="10.161.0.1", DSTMASK="255.255.255.0", NEXTHOP="80.1.1.10", PRIORITY=HIGH, REMARK="TO S-GW ROUTE"; //Deactivation procedure: RMV ADJNODE: ANI=0;

6.5 Parameter OptimizationNone.

6.6 Troubleshooting

6.6.1 Iu-PS in Non-pooled ModeFor Iu-PS in non-pooled mode, the RNC provides the Ping detection function to check theconnectivity of the IP path between the RNC and GGSN or S-GW. The ALM-21392 AdjacentNode IP Address Ping Failure is reported if the Iu-PS interface is faulty.

To enable the Ping detection function, run the ADD ADJNODE command with CHECKT setto ENABLED.

6.6.2 Iu-PS in Pooled ModeFor Iu-PS in pooled mode, the RNC provides the Ping detection function to check theconnectivity between the RNC and GGSN or S-GW. If the transmission between the RNC and



17

GGSN or S-GW is faulty, the ALM-21393 Adjacent Node IP Path Ping Failure orALM-21392 Adjacent Node IP Address Ping Failure is reported.

For details about the Ping detection function in pooled mode, see the Transmission ResourcePool in RNC Feature Parameter Description.
