ETSI ETSI TS 102 744-4-1 V1.1.1 (2015-10) 7 4 General 4.1 Overview The Circuit Switched (CS) domain is designed to carry only one active voice call per subscriber identity at any time. For User Equipment (UE) that is shared among users, e.g. on
32、 ships or aircraft, it is desirable to overcome this limitation and to offer the ability to handle more than one concurrent voice call. Additional voice calls can be provided by a Voice-over-IP (VoIP) service domain using the Packet Switched (PS) domain as its transport. The general principle of ope
33、ration assumes that the first preference is to use the CS domain to set up a call. Only if the CS domain is unavailable (i.e. one voice call is already in progress between the user and another party), will any additional calls be set up using the VoIP domain. The present document specifies the manda
34、tory requirements for equipment implementing a User Agent in the VoIP service domain. This User Agent is essentially providing a Private Branch Exchange (PBX) in the mobile domain, as shown in Figure 4.1, and is therefore referred to as “Mobile PBX“ throughout the present document. Figure 4.1: Equip
35、ment Configuration for support of Multiple Voice service A Mobile PBX can be implemented either as an integral part of a UE or as external hardware that can be connected to an existing UE. In general, the requirements specified in the present document apply to both implementations unless indicated o
36、therwise. 4.2 System architecture The solution described in the present document is based upon the integration of a VoIP domain containing infrastructure operating in tandem with the Circuit Switched domain and operating via the Packet Switched Domain. A simplified representation of the overall syst
37、em architecture is represented in Figure 4.2, where the VoIP domain is functionally provided by a VoIP server. ETSI ETSI TS 102 744-4-1 V1.1.1 (2015-10) 8 Figure 4.2: Overall System Architecture for support of Multiple Voice service A new VoIP Domain, provided via a VoIP server, is introduced into t
38、he Family SL ground segment, and provides an interface between the existing Circuit Switched domain and the Packet Switched domain for transport of multiple voice calls when the single CS voice circuit towards a mobile terminal is busy. The interface with the PSTN is handled by the existing Circuit
39、Switched domain for both mobile terminated and mobile originated calls. The existing voice mail system will be used to support per-MSISDN voice mail. Multiple MSISDN numbers are allocated to the subscriber. These numbers may be allocated to individual handsets by configuration of the mobile terminal
40、 or the external VoIP PBX. Alternatively functionality may be provided in the mobile terminal or VoIP PBX to determine which handset to alert upon Mobile Terminated call initiation utilizing the primary MSISDN. 4.3 Access to the VoIP domain The Mobile Terminal registers with the Radio Access Network
41、 and then initiates an Attach procedure towards both the CS and PS domains. During these Attach procedures the MT is authenticated, and Security Mode procedures are initiated to secure the signalling and user-plane between the Radio Access Network and the Mobile Terminal. ETSI ETSI TS 102 744-4-1 V1
42、.1.1 (2015-10) 9 Figure 4.3: Simplified Presentation of Initial Access Procedure Conditional on successful CS and PS attach procedures , the mobile terminal initiates a background Primary PDP context towards the Inmarsat VoIP APN, which is authorized by the HLR if the subscriber is granted access to
43、 Multiple Voice services. Conditional on the Mobile Terminal subscriber being authorized to access VoIP domain infrastructure, an IP address is allocated to the mobile terminal and the PDP context activated. The Mobile Terminal then performs a DNS lookup to obtain the IP address of the SIP server wi
44、thin the VoIP domain (the fully qualified domain name of the SIP server will be configured in the Mobile Terminal). The Mobile Terminal then initiates a SIP registration procedure towards the SIP server. 5 Mobile PBX Requirements 5.1 General Requirements 5.1.1 Number of Concurrent Calls The Mobile P
45、BX shall support a minimum of four concurrent voice calls (one call placed via the CS domain and an additional three placed through the PS domain). It should support up to nine concurrent voice calls. NOTE: The maximum number of concurrent voice calls supported is determined by the subscribers servi
46、ce package and is enforced by the network. 5.1.2 Support for Direct Inward Dialling Additional MSISDNs (AMISDNs) may be allocated to a UE network subscription to provide support for Direct Inward Dialling (DID) from another network to individual telephone handsets connected to the Mobile PBX. These
47、DID numbers shall be provided to the subscriber when they request a multiple voice service package from the satellite network service provider. The Mobile PBX may optionally support telephone handsets that are not associated with a DID number. Such handsets would typically be used for outbound calls
48、 only. 5.1.3 Support for Short Code Dialling The Mobile PBX shall support Short Code Dialling in both service domains. ETSI ETSI TS 102 744-4-1 V1.1.1 (2015-10) 10 5.1.4 Support for Call Barring The Mobile PBX should provide means to implement local barring of outgoing calls (whitelist and/or blackl
49、ist) to be applied either to individual handsets or to a group of handsets. 5.1.5 Configuration Requirements The Mobile PBX shall provide a suitable, user friendly interface for its configuration. As a minimum, the interface shall allow the user to change the following parameters through a suitable user interface: Access Point Name (APN) string apn_name SIP Domain Name string sip_domain_name It is recommended that these parameters are pre-configured by the manufacturer with default strings as advised by the satellite network service provider prior to
