Some services are specified as essential to enable operation of an internationalpaging system. A number of optional services are also described, which operators may include in theirsystems.The security aspects of the system are also included in this clause.4.1.2Framework for describing the servicesThe text associated with each service is structured in the following way:DefinitionThis paragraph provides a general definition and description of the service as it is seen by the user.Procedures-provision:-This paragraph indicates if the service should be essential or optional for the networkoperators of the ERMES system.-normal procedures:-This paragraph gives an indication of who (calling party, fixed or mobile subscriber) issupposed to activate the service and on what conditions it is made available to the users(e.g. per call basis or by registration).Network capabilities for chargingThis paragraph gives an indication of what charging arrangements the system shall be able to support.Interworking requirementsThis paragraph describes the interworking requirements between the different ERMES networks in orderto implement a service.SIST ETS 300 133-2:1999



Page 11ETS 300 133-2: November 1997Interaction with other servicesThis paragraph describes the interactions with other ERMES services when the service being described isactivated.4.1.3Essential and optional servicesEach service shall be considered as essential or optional for the network operator. In table A.1, theessential and optional supplementary services and facilities for each paging category is given.4.2Basic servicesThe system shall offer mobile subscribers levels of basic paging services according to the receivercapabilities. The system shall check that paging calls are not accepted to higher levels than the onecorresponding to the subscription. This check shall also take place on activation of a supplementaryservice, e.g. diversion of traffic.The ERMES system provides two kinds of call in each basic service:-individual calls that are initiated by using one Address Code (AdC) and are intended for only onemobile subscriber;-group calls that are initiated by using one Group Address Code (GAdC) and are intended for two ormore mobile subscribers.4.2.1Tone-only pagingDefinitionTone-only paging is the first basic service level and simplest kind of paging service, corresponding to thetraditional type of radio paging. The tone-only service means that paging signals to a particular receivershall cause the receiver to generate a simple alert signal. The system shall support up to 8 different alertsignals per Radio Identity Code (RIC). The system shall transmit the message within a message deliverytime depending on the level of priority (see subclause 6.2).Procedures-provision:-This essential service shall be provided by all network operators. It shall be implemented inthe Paging Network Controller (PNC) and all types of receivers, except transparent datareceivers. The service may be implemented in the transparent data receiver.-normal procedures:-Tone-only paging can be activated by the calling party by any Public Switched TelephoneNetwork (PSTN) telephone on a per call basis to a mobile subscriber in the system. It mayalso be activated by other terminal equipment.Network capabilities for chargingThe service should be charged on subscription and/or on a per call basis according to the networkoperator's policy.Interworking requirementsNone.Interaction with other servicesA number of supplementary services can not be activated when tone-only calls are sent (see table A.1).SIST ETS 300 133-2:1999



Page 12ETS 300 133-2: November 19974.2.2Numeric pagingDefinitionNumeric paging is the second service level. It allows transmission of up to at least 20 numeric or specialcharacters. This service is intended for mobile subscribers using pagers with the capability to receive,store and display numeric information in addition to tone-only paging. The character set is included intable B.1. The system shall transmit the message within a message delivery time depending on the levelof priority (see subclause 6.2). The maximum message length that the ERMES system can support is16 000 numeric characters. The network operators shall provide for a maximum message length between20 and 16 000 numeric characters. Messages longer than the maximum message length that a specificreceiver can accept shall not be delivered. The calling party shall be informed that the message is toolong (see also subclause 4.2.4 for very long messages).Procedures-provision:-This essential service shall be provided by all network operators. It shall be implemented inthe PNC as well as in numeric and alphanumeric receivers. The service may be implementedin the transparent data receiver.-normal procedures:-The service can be activated by the calling party on a per call basis to a mobile subscriber inthe system.Network capabilities for chargingThe service should be charged on subscription and/or on a per call basis according to the networkoperator's policy.Interworking requirementsNone.Interaction with other servicesNone.4.2.3Alphanumeric pagingDefinitionAlphanumeric paging is the third service level. It allows transmission of text information with up to at least400 alphanumeric characters. This service is for mobile subscribers using receivers with the capability toreceive, store and display text information in addition to tone-only and numeric paging. The basiccharacter set is defined in table B.3. The system shall transmit the message within a message deliverytime depending on the level of priority (see subclause 6.2). The maximum message length that theERMES system can support is 9 000 alphanumeric characters. The network operators shall provide for amaximum message length between 400 and 9 000 alphanumeric characters. Messages longer than themaximum message length that a specific receiver can accept shall not be delivered. The calling party shallbe informed that the message is too long (see also subclause 4.2.4 for very long messages).Procedures-provision:-This essential service shall be provided by all network operators. It shall be implemented inthe PNC and in alphanumeric receivers. The service may be implemented in the transparentdata receiver.SIST ETS 300 133-2:1999



Page 13ETS 300 133-2: November 1997-normal procedures:-The service can be activated by the calling party on a per call basis to a mobile subscriber inthe system.Network capabilities for chargingThe service should be charged on subscription and/or on a per call basis according to the networkoperator's policy.Interworking requirementsNone.Interaction with other servicesNone.4.2.4Transparent data pagingDefinitionTransparent data paging is a service allowing transmission of an arbitrary data stream to the receiver. Thesystem shall transmit the message within a message delivery time depending on the level ofpriority (see subclause 6.2). The use of the data stream is determined by the application chosen by thesubscriber. Only the part of the radio channel dedicated to the message allows a full bit transparency. Themaximum message length that the ERMES system can support is 64 kbits. The network operators mayprovide for a maximum message length of less than 64 kbits. Messages longer than the maximummessage length that a specific receiver can accept shall not be delivered. The calling party shall beinformed that the message is too long.Very long messages (longer than the defined maximum) can be sent through the ERMES system only ifthey are split into messages shorter than the maximum length. Users who wish to send such messages,may define a method of linking the parts of the messages together, between calling party and receiver.This method shall be transparent to the ERMES system, i.e. the parts shall be transmitted as separatemessages.Procedures-provision:-Provision of this service shall be optional for the network operators. Restrictions on themessage length can be imposed by the network operator according to his policy. It shall beimplemented in the PNC as well as in the receiver. Lower categories may be implemented inthe transparent data receiver.-normal procedures:-The service can be activated by the calling party on a per call basis to a mobile subscriber inthe system.Network capabilities for chargingThe service should be charged on subscription and/or on a per call basis according to the networkoperator's policy.Interworking requirementsNone.SIST ETS 300 133-2:1999

The offered supplementary servicesmay be used by the subscribers/users at their discretion.4.3.1Call related supplementary services4.3.1.1Acknowledgements4.3.1.1.1Valid input acknowledgementsDefinitionDuring the input of a call, acknowledgements shall be generated by the system to the calling partyindicating the call status. At least the following three types of acknowledgements shall be provided:a)call accepted acknowledgement:-The called AdC (individual or GAdC) is (is not) valid and the system is (is not) ready to acceptthe call. The calling party is invited to enter data referring to additional information or therequired supplementary service(s) or to enter the message.-A call shall be treated as unconditionally accepted when the home operator is able toguarantee a network status better than a threshold C in the areas in which the page isdestined for transmission (for the calculation of network status see ETS 300 133-3 [2]).-A call shall be treated as partially accepted when the network operator is only able toguarantee a network status between a threshold UC and a threshold C in the areas in whichthe page is destined for transmission.-The call shall be rejected when the network operator cannot guarantee a network statusgreater than a threshold UC in the areas in which the page is destined for transmission.-Each network operator shall define its own thresholds C and UC, which can be identical ifonly two call acceptance conditions are to be given to the calling party.b)supplementary service acknowledgement:-The supplementary service required is (is not) valid. The calling party is invited to enter datareferring to additional supplementary services or to enter the message.c)page accepted acknowledgement:-The message is (is not) valid.
