Definitions

  • the invention relates to a text or media message service, as well as to a mobile communication network being arranged to provide such service.
  • the GSM/3G feature Voice Group Call Service allows an entitled subscriber to establish Voice Group Calls for predefined groups (refer to 3G TS 43.068).
  • the initiator the entitled subscriber
  • the initiator can talk in the first phase till he gives up the talking rights by using Uplink release procedure.
  • the principle is that only one talker (first talker or subsequent talker) is allowed to talk at a certain point of time. (An exception is that up to five dispatchers can be involved in the group call and can talk simultaneously with the talking service subscriber. Each dispatcher uses a dedicated full duplex channel connected to the conference bridge) .
  • the GSM/3G feature Voice Broadcast Service has the similar functionality as the VGCS. It has only the exception from the VGCS that the VBS does not allow subsequent talker (refer to 3G TS 43.069) .
  • participant in a group communication should receive text messages which are addressed to the group (talking subscriber and subscribers in group receive mode) .
  • the text messages should be initiated by a member of the group or from someone not taking part in the group communication.
  • an object of the present invention to provide for an enhanced text or media message service, respectively, which facilitates the communication between plural users, in particular connected to a voice group call service. Furthermore, it is an object of the invention to provide for a correspondingly improved mobile communication network.
  • the invention covers the case that normal subscriber (which does not participate in the group call) or the current talker sends SMS to a group, and there is also a proposal how a listener can send an SMS.
  • the proposal of sending a text message from a listener is based on the additional functionality to support a second talker.
  • the invention provides for enhanced customer satisfaction due to the new functionality on sending SMS to a VGCS/VBS group and the functionality to allow a second talker in a VGCS/VBS call e.g. for sending SMS when there is a Talker already active in the VGCS/VBS call.
  • the originating of the SMS is the same as for standard SMS service defined in 3GPP TS 23.040. Only transmitting side is impacted by this proposal. The difference is that a destination address a group-call-reference is entered.
  • Anchor MSC may set a flag "message waiting data" and store the "SMS center address" for that particular group call. If the group call is established an indication to SMS-GMSC should be send that the group call is now active. If the delivery of the SMS is still pending at SMS Service center the SMS service center may trigger resending of the SMS.
  • Forward-SMS from SMS-GMSC to Anchor MSC is directed to MSISDN number.
  • Anchor MSC shall check if received MSISDN is a Group/Broadcast Call Reference and whether pertaining group/broadcase call is ongoing. If not then SMS shall be discarded. Otherwise MSC shall direct SMS to group/broadcast call resources in Anchor MSC and from there to BSS of Anchor MSC and to all Relay MSC-s. Forward-SMS from Anchor to Relay MSC
  • Forward-SMS service for transportation from Anchor to Relay MSC is preferred because Relay MSC can reuse implemented handling of Anchor MSC. Since Anchor MSC has to handle Forward SMS message from SMS-GMSC, the same principle can be reused in Relay MSC.
  • Opening new MAP connection would be advantageous, because it leads to the same reception handling of the existing Forward- SMS service.
  • New message shall be sent as BSSMAP message type on Call Controlling VGCS/VBS resource toward BSC.
  • BSC shall implement a distribution function for SMS. Since we foresee a similar concept for distribution of Talker Identity, this is not a novelty.
  • new message shall be used on Air Interface.
  • SMS shall be directed to all VGCS/VBS participating MS' s, which are basically in group receive mode. In such mode MS can operate only in Unacknowledged service, which limits length of Air interface message to 20 bytes. Since the maximum possible length of useful data to be transferred is around 142 bytes, segmenting mechanism is required on Air interface .
  • BSC acts as relay for SMS, therefore CP_DATA shall be sent on Radio Ressource controlling connections to BSS. Segmenting needs to be performed in BSS. Segmentation at MSC level is not preferred by MSC.
  • SMS can not be acknowledged in VGSC/VBS without server modifications of uplink access for MS in group receive mode. Since the number of MS in group receive mode is in principle unlimited, an access problem may occur. To develop feasible solution an upper limit of MS in group receive mode per VGCS/VBS cell shall be set first. We propose not to discuss this issue at this stage, but rather postpone it to eventual Stage 2 of GSM BOS project.
  • Delivery Report just acknowledges successful/unsuccessful transportation of SMS to all MSC of VGCS/VBS call.
  • MAP- VGCS-VBS-MT-FORWARD-SHORT-MESSAGE service The service is based on MAP-MT-FORWARD-SHORT-MESSAGE service. This service is used between the gateway MSC and the servicing MSC or the SGSN to forward mobile terminated short messages. Service should be used between Anchor MSC and Relay MSC of VGCS or VBS call.
  • the MAP- VGCS-VBS-MT-FORWARD-SHORT-MESSAGE service is a confirmed service using the service primitives given in table 12.9/1.
  • This parameter can contain either an IMSI or a LMSI.
  • the use of the LMSI is an operator option.
  • the LMSI can be provided if it is received from the HLR.
  • the IMSI is used if the use of the LMSI is not available.
  • This parameter is omitted in the mobile terminated subsequent SM transfers .
  • the short message transfer protocol data unit received from the Service Centre is inserted in this parameter.
  • a short message transfer protocol data unit may also be inserted in this parameter in the message delivery acknowledgement from the MSC or from the SGSN to the Service Centre.
  • Illegal equipment indicates that delivery of the mobile terminated short message failed because an IMEI check failed, i.e. the IMEI was blacklisted or not white- listed;
  • the reason of the SM Delivery Failure can be one of the following in the mobile terminated SM:
  • New MS state Group Receive and 2 nd talker mode shall be defined for MS supporting VGCS/VBS.
  • MS acts like in Group transmit mode, but shall exit the mode and return to Group receive mode as soon as it stops transmitting SMS.
  • SMS_to_VGCS/VBS contains up to 160 characters, where 7 bits are used per character; that presents total of 1120 bits, or 140 bytes.
  • the layout of SMS_to_VGCS/VBS information element is the following:
  • SMS content field is formatted as follows, when received in ForwardSMS at Anchor MSC:
  • SMS Since SMS is limited to maximum 1120 bits, in multiples of 7, 11 bits are reserved for coding of SMS length. In case of SMS being 160 characters long the total length of useful information is 1131 bits. In this case 5 filler bits shall be added to format A-interface message on byte boundary. Therefore maximum length of SMS content may be 142 bytes, and maximum length of SMS_to_VGCS/VBS IE is 144 bytes. In all cases where SMS content does not end on byte boundary filler bits have to be added.
  • SMS Reference is a random number, identifying an SMS in a segmented message. It shall be used by MS to reassemble SMS.
  • This message is sent in random mode on the voice group call channel uplink. It does not follow the basic format. This possible formats are presented directly below, without reference to information fields.
  • the order of bit transmission is defined in 3GPP TS 44.004.
  • the message is only one octet long, coded as shown in Figure 9.1.45.1/3GPP TS 44.018 and Table 9.1.45.1/3GPP TS 44.018.
  • ESTABLISHMENT CAUSE This information field indicates the reason for requesting the establishment of a connection. This field has a variable length (from 3 bits up to 8 bits) .
  • RANDOM REFERENCE This is an unformatted field with variable length (from 1 bits down to 0 bits) .
  • the Uplink access message is coded as follows:
  • fig. 1 shows the delivery of an SMS to ongoing VGCS/VBS in anchor MSC area
  • fig. 2 shows the delivery of an SMS to ongoing VGCS/VBS in relay MSC area
  • fig. 3 shows the unsuccessful delivery of an SMS to VGCS/VBS which is not active
