The present document gives the stage 3 description of the Multicall (MC) supplementary service within the 3GPP system. The co
20、ntents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as fol
21、lows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc
22、. z the third digit is incremented when editorial only changes have been incorporated in the document. ETSI ETSI TS 124 135 V15.0.0 (2018-07)53GPP TS 24.135 version 15.0.0 Release 151 Scope The present document gives the stage 3 description of the Multicall (MC) supplementary service. The present do
23、cument specifies the procedures used by the radio interface for normal operation, registration and interrogation of the Multicall supplementary service. Provision, withdrawal, erasure, activation and deactivation of supplementary services is an administrative matter between the mobile subscriber and
24、 the service provider and causes no signalling on the radio interface. 3GPP TS 24.010 describes the general aspects of the specification of supplementary services at the layer 3 radio interface. 3GPP TS 24.080 specifies the formats and coding for the supplementary services. Definitions and descripti
25、ons of supplementary services are given in 3GPP TS 22.004, 3GPP TS 22.072, 3GPP TS 22.08x, 3GPP TS 22.09x-series and 3GPP TS 22.135. 3GPP TS 22.135 is related specifically to the Multicall supplementary service. The technical realisation of supplementary services are described in 3GPP TS 23.011, 3GP
26、P TS 23.072, 3GPP TS 23.08x, 23.09x-series and 3GPP TS 23.135. 3GPP TS 23.135 is related specifically to the Multicall supplementary service. The procedures for Call Control and Mobility Management at the layer 3 radio interface are defined in 3GPP TS 24.007 and 3GPP TS 24.008. The following supplem
27、entary services are described in the present document: - Multicall (MC) (see clause 4). 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication, e
28、dition number, version number, etc.) or non-specific. - For a specific reference, subsequent revisions do not apply. - For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the

33、 4.1 Normal operation All of the radio signalling specific to Multicall is at the served mobile subscriber side. The radio signalling on the other side uses basic call signalling procedures only. The mobile subscriber supporting Multicall shall include the stream identifier (SI) information element.
34、 The purpose of the stream identifier (SI) information element is to associate a particular call with a Radio Access Bearer (RAB), and to identify whether a new traffic channel is requested for the call. Refer to TS 24.008 for the rules on allocating stream identifiers. 4.1.1 Mobile originating call
35、 (request a new traffic channel) If the served mobile subscriber initiates an outgoing call (A-B), the mobile subscriber shall include the stream identifier (SI) information element in the SETUP message. When there are no other ongoing calls, the following rules apply: - The stream identifier value
36、shall be equal to 1. - CC capabilities that indicate Nbr_UE shall be included in the SETUP message. - NW CC capabilities that indicate the network supports Multicall shall be included in the CALL PROCEEDING message. - If the NW CC capabilities is not sent from the network, the mobile station shall a
37、ssume that the network does not support Multicall, and shall not initiate an additional mobile originating call via a new bearer. - If the network receives the SETUP message with a stream identifier including an invalid content (SI value indicates other than 1 for the first call), the network shall
38、initiate call clearing with cause #95 “semantically incorrect message“.

40、he unsuccessful case of simultaneous Call in Setup 4.2 Registration The following information has to be registered in the network: - The maximum number of bearers chosen by the user, Nbr_User. 4.2.1 Registration by the served mobile subscriber A Multicall registration request from a mobile user shal
41、l include the SS-Code of Multicall. The request applies to all basic services. If the registration is successful, the Multicall service will be registered. The network will then send a return result indicating acceptance of the request including the value of Nbr_User. If the MS does not send an SS V
42、ersion Indicator in the invocation request then the network shall send an SS-Status in the result. If the MS does send an SS Version Indicator in the invocation request then the inclusion of SS-Status in the result is optional. If the SS-Status is included the network shall set it to reflect the sta
43、te of the service. The MS shall ignore the contents of the SS-Status parameter if one is received. See figure 9. If the system cannot accept a registration request, a corresponding error indication is returned to the served mobile subscriber that Multicall registration was not successful. Error valu
