4.1 General As MSs accumulate new applications and become more advanced, OTAM configuration has become increasingly important as new updates and services come on stream. OTAM optimises the configuration data updates in MSs and enables the distribution of new software updates to MSs with the necessary settings. OTAM messaging provides remote control of MSs for service and subscription activation, personalization and programming of a new service or feature.
Over-the-air management (OTAM) may refer to:
• over-the-air programming (OTAP):
• methods of distributing new software updates to MSs ("Firmware Over The Air", FOTA);
• Over the air management of encryption keys.
Mechanisms for Over-the-air management should be safe, secure and fault tolerant.
4.2 Over the Air Programming Currently every MS has to be connected to a programming tool to change features. E.g. cars have to be taken out of service and have to be moved to a Service centre to have the reprogramming done. Such a reprogramming procedure requires careful planning and logistics. During the reprogramming procedure dispatchers may have to deal with different and operationally conflicting group lists.
Over-the-Air Programming (OTAP) provides an easy, fast and more economical alternative to the cumbersome programming procedure described above. OTAP is a mechanism to read and write MS configuration over the air.
In an advanced OTAP enabled TETRA system a new MS only programmed with an ISSI and encryption keys can be provided with the operational configuration parameters and settings at first log-on.
4.2.1 TMO over the air Group Management TMO over the air Group Management enables a dispatcher to send one or more (dynamic) groups to MSs and optionally instruct the MSs to switch to one of the new groups. TMO over the air Group Management also enables the dispatcher to remove one or more groups from MSs.
• In PSS operations, a dispatcher can assign a dynamic group to a specific operational task, which is sent to all MSs of the people assigned to the task. In the group assignment the MSs are instructed to switch to the new group. After completion of the operational task the dispatcher will de-assign the dynamic group after which the MSs will delete the group and return to their original group. This allows temporarily allocation of a Public Safety group to MSs belonging to other Public Safety and even non-Public Safety users on the same system.
• TMO over the air Group Management can also be used to apply small fleet map changes to many MSs with little effort. For example, in a countrywide system, an MS that will be used in a different part of the country can have its group plans dynamically adjusted to adapt to the local conditions. On returning to its original jurisdiction, the MS can be changed back to its home settings just as easily as it was adjusted for use elsewhere.
In this way TMO over the air Group management can promote operational interoperability.
• Another use-case for TMO over the air Group Management is to not to program groups into MSs at all. The dynamic model allows flexible deployment of MS to the users. When starting their shift the users log on to the system and (only) receive all the necessary groups (typically less than 10 groups) to perform their tasks. At the end of the shift users log off and the groups are removed from their MSs.
An MS supporting TMO over the air Group Management can be shared via a pool and a single MS can carry multiple roles. In this way the organisation can optimize the MS investment.
Another advantage is for the MS user. Because the MS only has the necessary groups the chance of selecting a wrong group is small.
4.2.2 DMO Group and Frequency Management In national TETRA networks for public safety services (PSS) the users also need to communicate independently of the network via DMO. For this purpose, PSS network operators identify frequency channels for DMO usage and assign these frequency channels to dedicated PSS. This assignment depends on the respective PSS and/or the geographical region the PSS operates in and can change when PSS users move to different geographical regions or when a PSS network operator shifts already identified DMO frequency channels from one PSS to another one.
DMO over-the-air group and frequency management avoids mass re-programming of MSs whenever a change occurs.
There are at least two types of over-the-air management needs related to DMO groups.
• Use case 1 - Location based activation/deactivation
• Use case 2 - Changing the DMO frequency
4.2.3 Over the Air Phonebook Management The phonebook of an MS is used to show the alias of the talking parties in a group call or to start an individual or telephone call.
It is more than desirable to enable users to enjoy access to their contacts in their MS, without needing to re-input them for any new MS they acquire.
With OTA Phonebook Management it should be possible to update the phone book in the MS. Only changes to the existing phone book will be updated.
The MS communicates with a central address database to verify that the phone book contains all the required numbers (ISSIs and phone numbers) and contact information for the specific organization and owner of the MS. If necessary, new or changed ISSIs or telephone numbers and contact information are downloaded from the central address database to the MS phone book.
A typical use case may be updating a phonebook at the start of a shift.
Depending on the settings in the MS it is allowed for the user to make changes in the received Phonebook.
4.2.4 Over the Air management of Parameters and Settings OTAP should provide a standard mechanism for remote management of selected sets of MS settings and parameters.
All customisation parameters need to be accessible via OTAP but in general only certain parameters will need updating.
The mechanism will need to be one that only allows authorised entities to make changes.
OTAP will be used to update some parameters in the MS after a change in an operational procedure. The parameters involved can be technical, audio or MMI related parameters. For management reasons it is necessary to have an up to date overview of the actual setting of parameters in the MS. With OTAP it possible to query or download parameters from the MS.
Modify and query MS related parameters:
• Query MS information e.g. information about manufacturer, model, serial number, hardware version, firmware
version, dataset version, maximum power, supported features:
• Query MS status e.g. mode of operation (V+D, DMO, DM-GATE), battery charge, error reports.
• Modify and query MMI configuration e.g. configuration of shortcuts/function keys, audio configuration, display configuration, configuration of available menus, configuration of physical interfaces (PEI, external
keys, alarm contact, accessories:
• Change of audio parameters after selection of a new audio accessory.
If the user organisation selects a new audio accessory to be connected to the MS OTAP will be used to set the audio parameters to the desired values.
Modify and query network related parameters:
