Abstract

(see attachment) We are disclosing a method to communicate significant events, such as subscriber unit and talkgroup affiliations, between Serving and Home RFSSs. In one embodiment, an RFSS subscribes for Unit Affiliation Data by means of a SIP Subscribe method, customized for ISSI interface, for event notifications regarding Subscriber Units for which it is the Home RFSS. The sub As a further improvement, an RFSS may subscribe for Group Affiliation Data, by means of a SIP Subscribe method, customized for ISSI interface, for event notifications regarding talkgroups that have active affiliations, for which the subscribing RFSS is the Home RFSS. The sub In an alternate embodiment, an RFSS, acting as a Serving RFSS for an SU or SG, periodically pushes event notifications to an SU?s or SG?s Home RFSS in the form of a SIP Publish method, customized for ISSI interface, containing Unit or Group Affiliation Data. The Unit Affiliation Data will consist of all talkgroup affiliations made by units, which are home to the RFSS, to which the notification is being pushed. The Group Affiliation Data will at minimum consist of Subscriber Units affiliated to the talkgroups that are home to the RFSS to which the information is being pushed.

Interoperable Event Notification

ABSTRACT

A method to communicate significant events, such as subscriber unit and talkgroup affiliations, between subsystems over a subsystem interface which may include subscription for affiliation data notifications or publishing of affiliation data between subsystems. 

PROBLEM

Within a Radio Frequency Subsystem (RFSS), a vendor can supply various mechanisms to record and publish significant events, which occur within an RFSS. Such events provide visibility to information that enables public safety system operators and/or console dispatchers to make important decisions in managing an incident. The definition of interoperability standards, such as Telecommunication Industry Association (TIA) Inter-RF Subsystem Interface (ISSI) and Console Subsystem Interface (CSSI), allows interoperability between agencies with infrastructure supplied by different vendors. The ISSI and CSSI specifications, however, do not currently define a mechanism to convey a similar set of significant event information as is available in a single system. Principally, there is lack of information provided in the home subsystem of a Subscriber Unit (SU) or a Subscriber Group (SG) regarding activities which occur within a foreign subsystem, such as affiliations to foreign talkgroups made by a roaming Subscriber Unit.

 

SOLUTION

The public safety system operator and/or console dispatch operator must be enabled to see significant events for all of the SUs and SGs, which are home to the system.

To extend familiar monitoring services to an interoperable solution a new method of exchanging significant event data, such as unit or talkgroup affiliation information, is introduced as an extension of a subsystem interface.

Possible solutions may consist of a Radio Frequency (RF) or a Console subsystem subscribing for affiliation data event notifications for any number of Subscriber Units or Subscriber Groups that it has interest...
