31、g. Control characters 0/0 to 1/15 and 7/15 are not used within this protocol. Characters 8/0 to 15/15 are reserved for network operator use. 5 Data Link message and parameter codings 5.1 Data Link message and general parameter requirements 5.1.1 Data Link Message A Data Link message (for simplicity:
32、 a message) is generally related to a given service, but can be used in support of several different applications (each of them requiring different parameters). For each message type (or for each service if the same message type is used for different applications) a list of parameters is defined. Pa
33、rameters may be sent in any order within a message. A message can contain parameters for network operator use only. A range within the Message type coding is reserved for network operator use. 5.1.2 Parameter A parameter shall be used only once in each message. The parameter “Extension for network o
34、perator use“ (see clause 5.4.27) shall be included in the message when a reserved value for network operator is used in Message type, Parameter type or Parameter data value. The same parameter may be used within different messages (or different services). Parameters can be either mandatory or option
35、al according to the service description. A range within the Parameter type coding is reserved for network operator use. A range within the values of a parameter can be reserved for network operator use. ETSI ETSI ES 200 659-3 V1.4.1 (2004-08) 8 5.1.3 TE considerations The TE does not need to know wh
36、ich parameters are mandatory/optional. The TE decides how to handle the parameters (e.g. to display information or not). The TE should discard a parameter with an unknown value. The TE should discard an unknown message. The TE should discard an unknown parameter in a known message, keeping the known
37、 parameters. If mutually exclusive parameters are found in a message, the TE should discard the message. If two or more of the same parameters, but with different values, are found in a message, the TE should discard the message. If two parameters within a message are identical (same type coding val
38、ue) the TE should discard the second parameter. If the TE recognizes the “Extension for network operator“ parameter data, it should process the network operator specific Message and/or Parameter in accordance with the network operator specifications. If the TE does not recognize the “Extension for n
39、etwork operator“ parameter, the TE should discard: the complete message, if it is a network operator specific type of Message; the parameter, if it is a network operator specific Parameter or Parameter value. 5.2 Data Link message types Table 1 summarizes the messages supported in the present docume
