5.1.2 Test strategy
As the base standard ES 283 003 [1] contains no explicit requirements for testing, the TPs were generated as a result of an analysis of the base standard and the PICS specification TS 186 012-1 [2]. The criteria applied include the following: • whether or not a test case can be built from the TP is not considered.

4.1 IMS/MMtel
An IMS/NGN benchmark is required to allow not only a complete IMS network but also subsystems of a network corresponding to discrete products that may be available from a supplier. To address this requirement in this multi-part deliverable, a series of subsystems are defined, which will serve as a System Under Test (SU...

4.1.1 Session Control Subsystem (SCS)
The Session Control Subsystem (SCS) consists of the P-CSCF, I-CSCF, and S-CSCF, and HSS components, as depicted in figure 2. A valid SCS configuration consists of the set of x-CSCF building blocks, as well as the database functions HSS and SLF that support their functionality. The reference points for the SCS are the G...

5 Use cases
The following use cases, and corresponding tests, are currently defined. This clause attempts to define a set of basic use-cases and further ones can be defined similarly. These newly defined use-cases, or modifications to the ones presented here, will have to be described in a similar manner in the test report.

5.1.1 Registration/de-registration use-case 1
Registration is the first use-case that is employed when using an IMS network. During this operation the UE announces its contact location to the home domain registrar in order for the home network to route terminating messages towards it. It is performed by an UE when it is turned on. De-registration is the last opera...

5.1.1.1 Definition
The registration/de-registration is the process by which a UE announces, updates or deletes its location information to the home domain"s registrar. This operation is authenticated and a secure communication channel for subsequent signaling is set-up between the UE and the network.

5.1.1.2 Scenarios
While the scenario describe actions on the part of the UE, the portion of the signaling path between the UE and the complete IMS system outside the System Under Test configuration are simulated by the test environment with test system characteristics fixed with stated values. 5.1.1.2.1 Use Case 1- Scenario 1 - Successf...

5.1.1.2.7 Use Case 1- Scenario 7 - Re-registration - user currently registered
To refresh the registration timer the UE sends a re-registration request before the expiration time expires. This should be sent either 600 seconds before the expiration time if the registration time was greater than 1 200 seconds, or when half the registration time has passed when the registration time was under equal...

5.1.1.2.8 Use Case 1- Scenario 8 - Re-subscription - user currently registered
As the subscription might have a different expiration timer as the registration, re-subscription is not necessarily linked to re-registration. The process is detailed in figure 10. Figure 10: Re-subscription - user currently registered signaling flow

186 008-2
5.1.1.2.9 Use Case 1- Scenario 9 - Re-registration - user roaming
When the UE is roaming to another visited network, the procedures are similar to those of initial registration. As there are no security association set-up with the new P-CSCF, the initial REGISTER request will be authenticated. The network will internally take care of the old registration, without any UE interaction.

5.1.1.2.10 Use Case 1- Scenario 10 - UE initiated de-registration
When the UE requires terminating immediately the registration it can do so by issueing a REGISTER request with an expiration timer set to "0".

6 Session set-up/tear-down scenarios
This use-case corresponds to a normal 2-party call. The "session set-up" part refers to the establishment of the call and the "session tear-down" to its destroyal.
