The intent of this Study is to assess the ability of 3GPP specifications to meet requirements identified for Paging Permission w

24、ith Access Control. This Study considers the following aspects: - Identify requirements and aspects for Paging Permission with Access Control. - Perform a Gap Analysis to assess the ability of existing 3GPP specifications to meet the requirements and aspects. Regarding use-cases, followings should b

25、e studied in order to identify issues which are caused by the existing access control mechanism which does not allow UEs applied the access class restriction to establish terminating calls (non-exhaustive list): - Priority Service. - Emergency Service. - Communication between UEs in the same area wh

26、ere access control is performed This study should focus on providing this service using the CS/PS domain. This study includes the aspect of originating call and terminating call. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of t

(ffs) 4 Use cases 4.1 Priority service with congestion of terminating side There is a priority communication service which is applied to an authorised use

35、r (e.g. government, emergency responder) using priority mechanisms such as special access class (i.e. access classes 11 to 15) allocation and high priority level allocation of eMLPP. The service is effective in giving an important direction in disasters (e.g. earthquakes) which direction is to lead

36、to saving life. This direction should be transferred even if terminating side is in congestion caused by traffic used for confirmation of the safety of people in the disaster areas because the authorised users orders some agencies or people in the disaster areas to take an action for saving life. Us

37、e-cases are described below. (Note: not exclusive) - Case1: Disaster risk management office in government calls to emergency responder within disaster areas in order to supply temporary service to the disaster areas. - Case2: Ambulance attendant who gets to a rescue site in the disaster areas but do

38、es not found out a person calling for help because of unexpected destruction calls to him/her in order to make sure where he/she is. ETSI ETSI TR 122 908 V13.0.0 (2016-01)73GPP TR 22.908 version 13.0.0 Release 13Figure 4.1-1: Case2 - Case3: Firefighter at a fire of high-rise apartment in the disaste

39、r areas calls to a person losing his/her way in order to give out directives on the evacuation. Figure 4.1-2: Case3 Following considerations are identified from subscription aspect. In the case1 both of the originating users and the terminating users are the authorised users. Whereas in the case2 an

40、d 3 the originating users are the authorised users and the terminating users are not the authorised users. 4.2 Emergency service call back with congestion of terminating side A user in the disaster areas sets up an emergency call and it is unfortunately released. At the condition, emergency agencies

41、, e.g. police, would like to call back to the user. The call back should be established even if the network which the user resides in is in congestion caused by traffic used for confirmation of the safety of people in the disaster areas. ETSI ETSI TR 122 908 V13.0.0 (2016-01)83GPP TR 22.908 version

42、13.0.0 Release 13Figure 4.2-1: Use-case of emergency call back In Japanese background, the emergency call back is important. The new laws in the field of emergency service will go into effect in 1st April 2008. As one of the service requirements in emergency call, once an emergency call is establish

43、ed it can only be released by the PSAP operator and whenever PSAP request to call back, operator is required to successfully establish the call back to the user who made the emergency call. 4.3 Communication between UEs in the same area where access control is performed There are many earthquakes in

44、 Japan and it is hardly possible to predict when and where earthquake happens, therefore the approach to increase installed capacity in all the areas that costs considerable much is impossible. In order to produce communication in congestion conditions in the earthquake, it is not only efficient fro

45、m installed capacity aspect but also vital from service aspect to perform “access control interval application“ that description below explains. There is an area where access control is performed. In order to allow all the users in the area to setup calls, broadcasting access class numbers are chang

46、ed at an interval of some seconds. For example, in an interval UEs with access class 0 can perform setup and UEs with access classes 1-9 cannot do setup, in another interval UEs with access class 1 can do setup and UEs with access classes 0, 2-9 cannot do setup.

The communication helps users in the emergency situation. Following are use case

49、he unauthorised users 5 Considerations 5.1 Considerations with access class control Regarding communications in the condition where the originating users are the authorised users and the terminating users in the disasters are not the authorised users as identified in the use cases in section 4.1, there is an issue that the authorised user cannot access to the unauthorised user in the condition that access class control barring is applied to the unauthorised users. Regarding emergency service call back as identified in section 4.2, there
