2.5 Software License Management
OpenScape License Management (HLM) is used in the DECT Manager &
Integrator. The Unify licensing process consists of 4 different steps, see for a
general overview Figure 10:
1. The license key is centrally created and contains one "Base" with the SIEL-
ID and the number of "DECT Manager" (in case of small and medium this will
be one) for a Cordless IP system. The license file is signed by Unify CA.
2. The license file is being download from a License Server (CLS, Central
License Server). In general, the Customer Site Components (CSC) are part
of the license SW of the product that interpret the license file and distribute it
in a customer's network. In detail, the Customer License Agent (CLA) -
usually on the Unify communication server - connects to the License Server
and downloads the license file. Via CLA the customer can monitor the usage
of licenses.
If the CLA is located on the Unify communication server, the license file is
downloaded onto the Unify communication server. A Customer License Client
(CLC) which is always on DECT Manager & Integrator, is told, under which
link on the Unify communication server it can contact the CLA.
3. Verification of the license key: the license file is read in and the signature is
checked. If the check is successful, the license data will be retrieved from the
license file. This is done by CLA.
4. License Enforcement: the license conditions are checked and supervised in
the running system, e.g., as soon as a DECT IP Basestation is installed and
added to the system, the CLC contacts the CLA and a license counter in the
license file is decremented. This step is performed by the Customer License
Client (CLC) that is always running on DECT Manager & Integrator.
Figure 10 shows the OpenScape Cordless IP license management as part of the
OpenScape License Management. CLS is the Central License Server. CLA is
usually installed on the same Server as the Unify communication server. In DECT
Manager & Integrator, the CLC module is integrated, which is the interface to the
CLA.
