During an established radio contact, theimplicit detach timer shall be prevented from triggering implicit detach. Where a timer is shown in this specification,therefore, it is an application timer rather than a protocol timer.

The action taken by a MS in order to provide location information to the PLMN will be referred to as location updating. Should the TSG modify the contents of the present document, it will be re-released by the TSG with anidentifying change of release date and an increase 23.18 version number as follows: 3gpo procedure willnormally be used when the MS has moved to an area controlled by a different location register.

Upon receipt of this message,the VLR shall follow one of two possible courses of action. If a supervision timer expires beforea distant entity responds to a signal, the handling is as defined in 3G TS Below follows an overview of these procedures.

The contents of the present document are subject to continuing work within the TSG and may change following formalTSG approval. Functionally, there are two types oflocation registers: This Specification is provided for future development work within 3GPP only.

An MSC area may consistof several location areas. If a successfully authenticated radio connection has not been established before the Abort message is received, the VLR shall abort the Update Location Area process and return to the idle state. No No Authentication Yes sets available? Where a timer is shown in this specification,therefore, it is an application timer rather than a protocol timer.

The two possible courses of action and the conditions determining which course shall be taken are as follows: The locationinformation for each MS is stored in functional units called location registers. This is to be distinguished from the corresponding protocol handlingbehaviour, which is specified in 3G TS It is used in theVLR for call handling as calling party and as line identity. In general, the protocol handler reportstimer expiry to the application as an error condition or negative response.

They do not impose any requirement except thedefinition of the externally visible behaviour.

In the case of a reference to a 3GPP document including a GSM documenta non-specific reference implicitly refers to the latest version of that document in the same Release as the present document. The present document has not been subject to any approval process by the 3GPP Organisational Partners and shall not be implemented.

At the release of the radio connection, theimplicit detach timer shall be reset and restarted. MSC A rea Re stricte d? Create your own flipbook. No Wait for time expiry Figure 4. A location areaconsists of one or more cells.

A possible mechanism is 3fpp in section 4. In addition, for the purposes of the present document, the following abbreviations apply: Any response from the location register shall similarly be conveyedto the MS. No Authentication accepted Result:
