6 Operations, administration, maintenance, and provisioning p. 32

This clause specifies the network management and operational aspects of a Priority Service implementation.

6.1 Priority level assignment p. 32

A national or regional authority determines who is authorized for Priority Service and assigns Priority Service level(s), if applicable. There should be a uniform assignment of the following values within the national/regional networks.

Service User Priority Level Assignment [1…n]
TS 22.011 Access Class
TS 22.067 eMLPP Priority Level
TS 48.008 queuing allowed (qa) Value
Precedence Level in the ISUP Precedence Parameter

6.2 Subscription management p. 32

Priority Service is a subscription-based service. Depending on the national/regional process for authorizing Priority Service, a clearly defined working relationship should exist between the subscriber (i.e., Service User), the authorizing entity/entities, and the Service Provider(s) to ensure that as changes to the Priority Service subscriptions occur (for example, approval/assignment/changes to priority level, revocation of Priority Service authorization, etc.) the subscription information in the HLR is updated.

6.3 Accounting / charging p. 33

As Priority Service is a subscription-based service, the subscription information should be sent from a Service Provider's ordering/billing operations support system for provisioning in the HLR.

The Service Provider is responsible for collecting charging information and billing the Service User for Priority Service. Billing could be in the form of a flat fee and/or per call or per minute fees, however this is agreed between the Service Provider and the appropriate national authority.

The Service Provider should be capable of providing a summary account to the national authority, or designated representative, providing Priority Service information. This report might be the bill detailing all the non-recurring charges, if any, incurred for Priority Service for the reporting period, for example, a one-time charge for the establishment of a new Priority Service user.

The report may also contain the following type(s) of information:

MSISDN
Service System Identification Number/Billing Identification Number
Home SID/BID
Number Dialled
Destination Location of Call (city, state, country)
Date of Call
Start Time
End Time
Minutes of Use
Premium Charge per Minute
Total Call Charge

The Call Detail Record (CDR) for the Service User should be able to differentiate between normal (non-Priority Service) and Priority Service calls.

6.4 Service provider responsibility p. 33

In addition to responsibilities outlined elsewhere in this document and in TR 22.950, Service Providers have the following responsibilities.

Provide Priority Service in accordance with the national and regional instructions and laws, and adhere to uniform operating access procedures.
As feasible, provide Priority Service to authorized roaming Service Users.

6.5 Service user responsibility p. 33

Priority Service subscribers (i.e., Service Users) are expected to invoke Priority Service during times of emergency and network congestion. If multiple levels are available, they are expected to be assigned and use the lowest level of priority applicable, and to identify their need for Priority Service in a planned method. This means that they try, to the best extent possible, to identify the need for subscription prior to an emergency occurring.
