(From Project No. SP-3-4652.802-RV2-RF1, formulated under the cognizance of the TIA TR-45 Mobile (b) there is no assurance that the Document will be approved by any Committee of TIA or any other body in its present or any other form; (c) the Document may be amended, modified or changed in the st
7、andards development or any editing process. The use or practice of contents of this Document may involve the use of intellectual property rights (“IPR”), including pending or issued patents, or copyrights, owned by one or more parties. TIA makes no search or investigation for IPR. When IPR consistin
8、g of patents and published pending patent applications are claimed and called to TIAs attention, a statement from the holder thereof is requested, all in accordance with the Manual. TIA takes no position with reference to, and disclaims any obligation to investigate or inquire into, the scope or val
9、idity of any claims of IPR. TIA will neither be a party to discussions of any licensing terms or conditions, which are instead left to the parties involved, nor will TIA opine or judge whether proposed licensing terms or conditions are reasonable or non-discriminatory. TIA does not warrant or repres
10、ent that procedures or practices suggested or provided in the Manual have been complied with as respects the Document or its contents.

11、blication of standards (whether designated as a standard, specification, recommendation or otherwise), whether such reference consists of mandatory, alternate or optional elements (as defined in the TIA Engineering Manual, 4thedition) then (i) TIA disclaims any duty or obligation to search or invest
12、igate the records of any other SSO for IPR or letters of assurance relating to any such Normative Reference; (ii) TIAs policy of encouragement of voluntary disclosure (see Engineering Manual Section 6.5.1) of Essential Patent(s) and published pending patent applications shall apply; and (iii) Inform
13、ation as to claims of IPR in the records or publications of the other SSO shall not constitute identification to TIA of a claim of Essential Patent(s) or published pending patent applications.

Subscribers may or may not be directly aware of the use of ser
23、vices that are independent of subscriber involvement. 1.1 Subscriber Confidentiality (SC) Subscriber Confidentiality (SC) allows the wireless system to assign an MS a Temporary Mobile Station Identity (TMSI) to be used in subsequent communications with the MS. The TMSI should not have an externally
24、visible association with the MSs permanent identity (MIN or IMSI). SC conceals the MSs permanent identity on the air interface and thereby protects the subscriber from fraudulent use of the MSs permanent identity. The wireless system should periodically reassign the TMSI. This further reduces the po
25、ssibility of associating the TMSI with the subscribers permanent identity. The TMSI should be reassigned in a manner that does not reveal the MSs permanent identity. When an MS with a previously assigned TMSI roams into a new system that is SC capable, the MS may not send its permanent identity over
26、 the air interface to the new system. It may send its TMSI only. The new system should uniquely identify the MS using this TMSI to obtain the MSs permanent identity and subscriber information through intersystem transactions. On the other hand, if an MSs TMSI is reestablished in each new system, int
27、ersystem transactions will not be needed. The wireless serving system shall provide system integrity when assigning TMSIs such that each assigned TMSI uniquely identifies a single subscriber within that wireless serving system. If the wireless system is not able to support SC, the wireless system shall allow the MS to operate with the permanent identity even though a TMSI was previously assigned in another system.
