38、h call using its own dedicated bearer. Only one CS bearer can used for speech at any one times. A speech call is one of TS11 (Telephony), TS12 (Emergency Calls), and TS61 (Alternate speech/fax). If the bearer capability information is not available, e.g. the call is originated/transited by a PSTN, t
39、he basic service cannot be deduced and the network shall, for multicall purposes, handle the call as telephony. A held call shall be regarded as using the bearer used while the call was active. NOTE: The 3GPP protocol architecture allows several parallel CS calls, the limitation being that there is
40、only one traffic channel in GERAN, which the different CS calls share. This is facilitated by e.g. the Call Waiting, Call Hold, Call Transfer and Multiparty Supplementary Services. Call configurations related to supplementary services are not considered as Multicall. See clause 7 for interaction. It
41、 shall be possible for each CS call to use a dedicated bearer of independent traffic and performance characteristics. It shall be possible to release each active CS call independently of any other CS call. 4.2 Applicability to telecommunication services The applicability of this Supplementary Servic
42、e is defined in 3GPP TS 22.004. 5 Functional requirements 5.1 Provision Multicall is provided by prior arrangement with the service provider. Multicall shall be provisioned for all Basic Services (BS) subscribed to and to which it is applicable, i.e. not to any subset of these BS. When the Multicall
43、 supplementary service is provisioned the maximum number of simultaneous CS beares available to the subscriber (Nbr_SB) shall be defined as part of the subscription. The value for Nbr_SB shall in the range from 2 up to 7. 5.2 Withdrawal It shall be possible to withdraw the Multicall supplementary se
44、rvice subscription on request of the subscriber or for administrative reasons. 5.3 Registration The user shall be able to modify the maximum number of CS bearers available (Nbr_User) within the limitations set by the service provider. (Nbr_SB). If the subscriber attempts to register a value for Nbr_
45、User that is higher than the value of Nbr_SB, the request shall be rejected and the subscriber shall be informed on the unsuccessful outcome on the request. 5.4 Erasure Data related to the Multicall supplementary service shall be erased by the service provider as a result of withdrawal. ETSI ETSI TS
46、 122 135 V15.0.0 (2018-07)83GPP TS 22.135 version 15.0.0 Release 155.5 Activation The Multicall supplementary service shall be activated by the service provider as a result of provision. 5.6 Deactivation The Multicall supplementary service shall be deactivated by the service provider as a result of
47、withdrawal. 5.7 Invocation The Multicall supplementary service shall be invoked by the system when at least one call is in progress and another call with a dedicated bearer is to be set up. The Multicall service applies to mobile originating and mobile terminating calls. 5.8 Interrogation The user s
48、hall be able to interrogate the network for the values of Nbr_User, Nbr_SB and Nbr_SN. 5.9 Call related procedures 5.9.1 Terminating CS call The indication of a terminating CS call to the mobile terminal will be done by the Multicall supplementary service until either the maximum number of bearer (N
49、br) or the maximum number of CS mobile terminating calls (Ncs_MT) has been reached. If the maximum number of terminating calls (Ncs_MT) has been reached, and additional terminating call shall be reject without any indication to the subscriber. If the maximum number of bearers (Nbr) has been reached an additional terminating call will be only indicated to the user if the user has the Call Waiting supplementary service active, see chapter 7.4.2 for interactions with Call Waiting. If Nbr and Ncs_MThavenot been reached, a terminating call is indicated to the u
