26、4 Description There are two modes of USSD: MMI-mode and application mode. MMI-mode USSD is for the transparent transport of MMI strings entered by the user to the network and for the transparent transport of text strings from the network that are displayed by the mobile for user information. Applica
27、tion mode USSD is for the transparent transport of data between the network and the UE. Application mode USSD is intended to be used by applications in the network and their peer applications in the UE. The communication over the radio interface takes place on the signalling channels using short dia
28、logues with peak data throughput rate capabilities of up to approximately 600 bits/s outside of a call and 1 000 bits/s during a call. 5 USSD operations MMI mode 5.1 Mobile initiated USSD operations 5.1.1 Initiating action at the User Equipment (UE) If the user enters an MMI string that, according t
29、o TS 22.030 3, should be treated as USSD, the UE shall send this string to the network using the appropriate operation from TS 24.080 5. ETSI ETSI TS 122 090 V14.0.0 (2017-03)63GPP TS 22.090 version 14.0.0 Release 14The mobile initiated operation shall contain an alphabet indicator and language indi
30、cator. The alphabet indicator shall indicate the alphabet used in the operation. The selection of values for these indicators is a matter for the user. The UE may initiate an USSD operation either during a call or out of call. 5.1.2 Action at the network A network supporting USSD shall examine the a
31、lphabet indicator. If the serving network does not recognize the alphabet indicated in the mobile initiated USSD operation, it shall send the operation to the HLR. On recognition of the alphabet, the network shall examine the contents of the string, and take appropriate action, according to the foll
32、owing rules, depending of the format of the message. Case a) 1, 2 or 3 digits from the set (*, #) followed by 1X(Y), where X=any number 0-4, Y=any number 0-9, then, optionally “* followed by any number of any characters“, and concluding with # SEND: This case is reserved for HPLMN use. When a servin
33、g network receives such a message from a visiting subscriber, it shall pass the USSD message directly to the HPLMN. If it receives it from a home subscriber, it is up to the network to decide whether to treat it locally or to pass it to the HLR. Case b) 1, 2 or 3 digits from the set (*, #) followed
34、by 1X(Y), where X=any number 5-9, Y=any number 0-9, then, optionally “* followed by any number of any characters“, and concluding with # SEND: This case is reserved for VPLMN use. It is up to the VPLMN to decide how to treat it. Case c) 7(Y) SEND, where Y=any number 0-9: This case is reserved for HP
35、LMN use. When a serving network receives such a message from a visiting subscriber, it shall pass the USSD message directly to the HPLMN. If it receives it from a home subscriber, it is up to the network to decide whether to treat it locally or to pass it to the HLR. Case d) All other formats: The v
36、isited network examines the message. If it is able, it acts upon it. Failing that, it passes the message to the HLR. If the HLR does not support the alphabet indicated, it shall inform the UE. The network shall terminate the mobile initiated operation by responding to the request from the mobile wit
37、h either an error signal, or a text string indicating the outcome of the operation. The response string uses the characters available in the selected alphabet as defined in TS 23.038 4. If no indication to the user is required, the response string may be empty. The response to the mobile initiated U
38、SSD operation shall contain alphabet and language indicators. The selection of values for these indicators is a matter for the network operator. 5.1.3 Mobile initiated USSD cross phase compatibility In situations of incompatibility the mobile initiated USSD operation will be rejected by a non-suppor
39、ting network and the attempt will fail. In this situation, if it is possible to encode the content of the USSD message in the IA5 alphabet, the UE shall attempt the operation again using the IA5 format without the alphabet and language indicators. This procedure is not applicable if an operation fai
40、lure is due to alphabet support problems, services not supported or network failure problems. 5.1.4 Allocation of service codes (to be noted by network operators) Service codes for use in control of Supplementary Services are standardized by international agreement, so must not be used by PLMNs unle
41、ss authorized, except for those codes allocated for PLMN use. If the message is of the format: ETSI ETSI TS 122 090 V14.0.0 (2017-03)73GPP TS 22.090 version 14.0.0 Release 141, 2 or 3 digits from the set (*, #), followed by NN(N), where N=0-9, optionally followed by “* and any number of any characte
42、rs“, and terminating in # SEND: then NN(N) is known as the service code. Only codes specified in TS 22.030 3 and those defined in cases a) and b) above may be used. All other values are reserved. Similarly, if the message is of the format: X(Y) SEND, where X=0-6 or 8-9 and Y=0-9: the codes X(Y) are
43、standardized. Only codes specified in TS 22.030 3 subclause 4.5.5 may be used. All other values are reserved. 5.2 Network initiated USSD operation 5.2.1 Initiating actions in the network At any stage while the UE is registered with a network, the network may send an unstructured string to the UE. Th
44、is string contains operator determined information that is relevant to the user. If the network is unable to successfully reach the UE, then an error shall be returned to the node that originated the operation. The network initiated USSD operation shall contain an alphabet indicator and language ind
45、icator. The alphabet indicator shall indicate the alphabet used in the operation. The selection of values for these indicators is a matter for the network operator. 5.2.2 Actions at the UE If the is unable to process the network initiated USSD operation (e.g. the feature is not supported or the user
46、 is engaged in another MMI activity) then an error indication shall be returned to the node that originated the operation. If the alphabet indicated by the network is not supported by the UE, the UE shall inform the network. The network may explicitly indicate to the UE that a response from the user
47、 is required. In this case, the next string entered by the user shall be used as the responseand this string is not interpreted according to normal MMI procedures stated in TS 22.030 3. An MMI command shall be provided to allow the user to terminate the dialogue with a null response. The response st
48、ring uses the characters available in the selected alphabet as defined in TS 23.038 4. The response is sent to the node that originated the operation. If the network does not indicate that a response is required, then the normal MMI procedures on the UE continue to apply. The UE shall include alphab
49、et and language indicators in the response to the network (if any). 5.3 Network aspects of USSD operation Applications that useUSSD operations may be located in either the HPLMN or a roamed to VPLMN. Network applications using USSD operations may: - use several USSD operations (possibly a mixture of mobile initiated and network initiated) in combination as part of a dialogue with the user. Linkage between separate operations as part of a dialogue is only implemented locally in the network application and does not lead to any special mode
