8ea3a70ff1bf865c2806c00ec5f889fd | 101 886 | 5.4 Number portability considerations | Number portability considerations are explained with an example using International UPT. The current number allocation for the UPT service of the VISIONng will be done through service providers.

8ea3a70ff1bf865c2806c00ec5f889fd | 101 886 | 5.4.1 Verification of the provisioning request | Any provision request SHALL be verified against a set of rules defined by the TRC. Invalid provisioning requests SHALL be ignored. Both valid and invalid provision requests SHALL be logged. |
8ea3a70ff1bf865c2806c00ec5f889fd | 101 886 | 5.4.2 Activation of the provisioning request | 1) The new service provider SHALL be able to specify the time/date when a particular provisioning request becomes effective. The subscription data SHALL be made available at the effective time/date. 2) If the activation is to be done immediately, the activation SHALL be done in a timely manner. |
8ea3a70ff1bf865c2806c00ec5f889fd | 101 886 | 5.4.3 Confirmation of the old service provider | If number porting is involved (e.g. a subscriber changes their service provider), the porting needs to be confirmed by the old service provider. |
8ea3a70ff1bf865c2806c00ec5f889fd | 101 886 | 5.4.4 Conflict resolution | 1) A process to resolve conflict SHALL be in place if the old and new service provider disagree on who will serve a particular subscriber. The TRC SHALL define the rules and process for conflict resolution. 2) Multiple provisioning requests for the same subscriber received before the subscription data becomes effective... |
8ea3a70ff1bf865c2806c00ec5f889fd | 101 886 | 5.4.5 Order cancellation | After sending a provisioning request for a number but before the effective date/time, the service provider SHALL be able to cancel the provisioning request (e.g. the subscriber decides not to switch or subscribe before the effective date/time). The old service provider SHALL be informed about the order cancellation. Th... |
8ea3a70ff1bf865c2806c00ec5f889fd | 101 886 | 6 Requirements for the RTDB | This clause describes the requirements pertaining to the real-time aspects of TRC. "SHALL" means mandatory, while "SHOULD" means recommendation, and "MAY" means optional. |
8ea3a70ff1bf865c2806c00ec5f889fd | 101 886 | 6.1 General | 1) RTDB SHALL resolve an E.164 number to an HNN, which is the name of the home service provider for the queried E.164 number. 2) It is outside of the scope of TRC to resolve an HNN to a next-hop network address. |
8ea3a70ff1bf865c2806c00ec5f889fd | 101 886 | 6.2 HNN | 1) An HNN SHALL uniquely identify a service provider within a resolution domain.

In the case of number resolution, a session starts with a query from the AD-BES of a... |
8ea3a70ff1bf865c2806c00ec5f889fd | 101 886 | 6.6 Performance | Performance of a database system is usually measured by three factors: query response time, throughput, and sizing. Query response time refers to the time between the last bit of query entering the database and the last bit of response going out of the database. In other words, query response time only concerns with th... |
