According to an embodiment, the MS that can in the extType variable, encode identification.Do not comprise optional PCS-Extensions in this exemplary embodiments.Should and not can be used to discern the IMSI or other MS ID that test MS with OI obscures.There is a length indicator that the eight bit word joint number of OI value is provided the front of the content of OI or OI " value ".
As incorporate into described in the list of references of this paper, ASN-1 OI makes it possible to be identified in clearly entity of registration in the world tree (worldwide tree).The characteristic of OI is known by the technical staff of wireless communication field, therefore no longer it is described in more detail herein.OI can be by suitable tissue or enrolment authority registration.An example of existing OI registration (similar with the OI registration that is suitable for an exemplary embodiments) is the OI registration of distributing to ASN-1 BASIC-PRE, UNALIGNED modification: { joint-iso-itu-t asnl (1) packed-encoding (3) basic (0) unaligned (1) } " compressed encoding of single ASN.1 type (basic misalignment) ".Available known PER hexadecimal format is represented suitable OI, and " extId " of the exemplary ASN-1 coding of its extension container shown in can be used for above.Example is decimally counted " 1,3,0,1 " and is represented OI hereto, and it can (0x03 be the variable length value of 3 eight bit bytes by PER hexadecimal sequence 0x03,0x2b, 00,01; 0x2b represents to be worth 43=40*1+3) encode.
In one embodiment, " extType " variable is the component that contains the proprietary extensions data of the IMSI that can be used to transmit test MS or other MS ID.It is the ASN-1 style of opening, so it has the length factor of determination, follows the field inventory thereafter.For this example, the length of proprietary extensions can be chosen as and be no more than 128 eight bit bytes.Therefore, can be in an eight bit byte or in 8 the code length factor of determination.In one embodiment, the field inventory of extType variable can have following form:
FieldList::＝SEQUENCE{
testExtRevision TestExtensionRevision，
imsi IMSI，

Test MS identification and exemplary operation by SMLC
In an exemplary embodiments, test MS is configured so that encode its relevant MS ID (for example, IMSI or MSISDN) in the extension container of measuring position response message 356 or in the extension container of protocol error message 346 and 354 (Fig. 3).As mentioned above, the measuring position response message is transferred to SMLC so that reported position is measured, AGPS measures or measure mistake.The protocol error transmission of messages is arrived SMLC to test MS so that the report protocol error.SMLC is configured so that the MS ID of the extension container of decoding, retrieval MS ID and storage and a unique location sessions identifier, and described unique location sessions identifier can belong to a plurality of location sessions identifiers of being preserved by SMLC.
When attempting to decode proprietary extensions, SMLC can at first attempt the OI that decodes.If OI that can not identification received, so SMLC can attempt skipping OI and the length of the opening variable of decoding so that skip whole proprietary extensions container.If the extension container prevention is correctly decoded RRLP message, SMLC can be with the position finding session of RRLP protocol error transmission of messages to MS and termination and BSC so.
No matter when SMLC detects with an indicating length greater than the value coding OI of 16K or the length factor of determination of ExtType, SMLC all with a protocol error transmission of messages to MS.SMLC stops the position finding session with BSC.
Advantageously, available test pattern parameter configuration MS.Usable levels " test pattern is opened " (abbreviating " opening " as) and " test pattern pass " (abbreviating " pass " as) are provided with described test pattern parameter, and wherein default value is " pass ".In MS, by utilize one in the phone serial link proprietary order or carry out described configuration by MS user interface (UI).Has only the coding that when the test pattern parameter is set to " opening ", just on test MS, activates the MS ID in the extension of message container.In one embodiment, has only the coding that when the test pattern parameter is set to " opening ", just on test MS, activates the MS ID in the extension container.
Fig. 4 is the flow chart of the step in explanation one exemplary methods.In step 402, MS receives message from SMLC.Exemplary message can comprise RRLP auxiliary data message or RRLP measuring position request message.Described method proceeds to step 404.
According to circumstances, MS can possess the test pattern parameter.MS ID and its do not have the test pattern parameter if MS encodes through programming, but skips steps 404 so, and described method is directly to step 406.If comprise the test pattern parameter among the MS, and it is set to out, and design also proceeds to step 406 so.If MS sends MS ID without programming, if perhaps the test pattern parameter is set to close, so described method proceeds to step 408.
In step 406, MS is its relevant MSID of coding in the extension container of a suitable response message, and described suitable response message is such as measuring position response message 356 (Fig. 3), protocol error message 346 and 354.Suitable message can comprise any message with extension container.Do not use other message that does not have extension container (such as the auxiliary data acknowledge message) that can send MS ID that encodes, and the step shown in Fig. 4 does not relate to described other message.Described method proceeds to step 408.
In step 408, MS is transferred to SMLC with suitable response message, and proceeds to step 410.
In step 410, SMLC handles described suitable response message, and proceeds to step 412.
In step 412, if SMLC is through suitably disposing so that retrieve MS ID from extension container, so described method proceeds to step 414.If SMLC fails to retrieve MS ID, so described method proceeds to step 416.If do not send MS ID (for example, test pattern is set to close), so described method also proceeds to step 416.
In step 414, SMLC storage for the MS ID of unique location sessions identifier of Test Engineer's reference, continues the conventional treatment function when needing then.
In step 416, SMLC can be by responding the position finding session of a RRLP protocol error transmission of messages to MS and termination and BSC before continuing the conventional treatment function.Perhaps, if MS does not send MS ID (for example, test pattern is for closing), SMLC also will continue the conventional treatment function in step 416 so.As another kind of may, SMLC can be before continuing the conventional treatment function with a RRLP protocol error transmission of messages to MS but do not stop position finding session with BSC.These possible responses that SMLC makes hereinafter further are discussed.
There are some favourable novel aspect.For instance, the enforcement of proprietary extensions only influences the operation of MS and SMLC.It can not influence the operation such as other network element of BSS, BSC or mobile switching centre's (not showing among the figure).Because transmit RRLP message pellucidly by BSC, and to have only the size of RRLP message be the factor that BSC handles this message, so described MS recognition methods and device can not influence other element.
Another favourable aspect relates to the interoperability between test MS and " nature " SMLC (just, not having to be configured the SMLC that is used for working according to the teaching of this paper in test pattern).Extension container (for example if SMLC can not decode, as contingent under the roaming situation, although roaming is an atypia situation of the operation of test MS), some kinds of possibilities can occur so: 1) when described natural SMLC detects existing of optional extension container, it may be selected not attempt decode messages and may transmit a protocol error message and respond; 2) when extension container was located at the end of message, described natural SMLC may attempt decode messages, but just stops decoding in case arrive extension container, thereby handled the message part of decoding before the arrival extension container; 3) extension container though described natural SMLC may be able to decode, its decision abandons proprietary extensions, because its not identification OI.For situation 2 above) and 3), the location operability kept.Yet, for situation 1 above), test MS will not have the location operability, unless implement the test pattern parameter and it is set to " pass ".
Another favourable characteristics relate to the size of RRLP measuring position response message.An additional proprietary extensions has increased the size of RRLP pay(useful) load, and this may be a problem aspect segmentation, especially concerning the response message of RRLP measuring position.Yet,, do not need the up link segmentation so if message size remains on 252 below the eight bit byte.Exemplary embodiments as described above is restricted to the increase of the size of RRLP message 128 eight bit bytes (120 eight bit bytes are the typical number that one group of GPS being used to report interrelate with 16 satellites measures) or is less than 128 eight bit bytes, will be above the possibility of 252 eight bit bytes thereby reduced complete RRLP message.
