23、 Selection (NDSS) The Network Directed System Selection (NDSS) feature is a network capability that provides a network based mechanism for a service provider, based on various customer and service provider specified criteria, to automatically direct a subscribers Mobile Station (MS) to a desired ser

24、ving system. The serving system could be any system available to the MS, regardless of frequency band (cellular A/B or PCS bands A/B/C/D/E/F) or technology (analog or digital). NDSS consists of procedures that allow wireless subscribers to register upon a preferred system while they are roaming (i.e

25、., outside of their home system) without manual intervention by the subscriber. NDSS allows an MS to automatically register with a preferred serving system or to be automatically directed by their home system to a suggested system based on bilateral agreements between the serving system and home sys

26、tem. When an MS registers on a visited system, the network may direct the MS from that system to another system. The network may provide information which controls the status of the Enhanced Roaming Indicator in the MS. NDSS may override system selection procedures in the MS. The subscriber should h

27、ave the ability, however, to suppress NDSS, and use the MSs system selection procedure. The status of NDSS (i.e., Active, Suppressed) is maintained in the home system, and may be changed upon request by the subscriber. Applicability to Telecommunications Services NDSS is applicable to all telecommun

28、ications services. 1.1 Normal Procedures with Successful Outcome Authorization NDSS may be made generally available for all subscribers by the service provider. Deauthorization NDSS may be withdrawn by the service provider. Registration NDSS has no registration. Deregistration NDSS has no deregistra

29、tion. Activation NDSS is activated upon authorization.

30、NDSS is deactivated upon deauthorization. Invocation NDSS is invoked by the home system upon receipt of a registration message. Normal Operation with Successful Outcome This section describes a typical sequence of procedures for a subscriber, whose home and serving systems offer NDSS, which results

31、in a successful outcome. a. The MS may scan a list of preferred systems. If no preferred systems are found, the MS registers with any available system, provided the system is not on the MSs negative system list. A negative system list is defined as a short list of unacceptable system identifications

32、 that is stored in the memory of an MS. These procedures are valid for all forms of registration (implicit, as well as explicit). b. The serving system requests authorization from the subscribers home system. c. The home system determines whether another system is preferable to the current serving s

33、ystem. d. If the home system determines that another system is preferable, and the subscriber has not suppressed NDSS, it may return information to the serving system requesting it to redirect the MS to a different system. If the redirection attempt is unsuccessful, the current serving system, while

34、 not preferred, is always assumed to be acceptable. e. If redirection has been requested by the home system, the serving system shall redirect the MS to the preferred system. f. The MS receives the redirection message and attempts registration with the new system. 1.2 Exception Procedures or Unsucce

35、ssful Outcome This section lists some of the more probable abnormal situations not described in Normal Procedures with Successful Outcome. Registration None identified. Deregistration None identified. TIA-664.531-B 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 3

NDSS may be activated by an authorized subscriber specifying the NDS

37、S activation feature code as in: *FC + SEND Deactivation NDSS is considered deactivated when the suppression of NDSS is turned on in the home system. The MS then reverts to its internal system selection procedure which was used upon initial system access. NDSS may be deactivated by an authorized sub

38、scriber specifying the NDSS deactivation suppression feature code as in: *FC + SEND Invocation If, for some reason, the MS cannot complete service redirection (e.g., registration rejection, invalid system identification, no system found, etc.), it registers with the original visited system and indic

39、ates the failure condition. Exceptions While Roaming None identified. Exceptions During Intersystem Handoff None identified. 1.3 Alternative Procedures None identified. 1.4 Interactions with Other Wireless Services Asynchronous Data Service (ADS) None identified.
