Benefits of technology

[0038]The Access Indicator Field can be used by the mobile terminal to determine if it is authorised to use the Access Point without the need for the mobile terminal signa

Problems solved by technology

Since these access points are not conventional base stations, however, additional challenges arise.
However, the capacity of such ADSL backhauls are limited, and not under the control of the telecommunications network provider, so there needs to be restrictions put in place on which user terminals (UEs) are able to access each AP in order to maintain an acceptable degree of service quality.
A problem that arises because of the need of such access restrictions is that UEs will be split into those which are authorised to access each AP and those which are not authorised to.
These access rejections are a waste of signalling resources.
This is particularly a problem where an A

first embodiment

[0081]With this background in mind, an implementation of the invention will now be described, which seeks to minimise unnecessary signalling in regard to closed APs.

[0082]Conventionally, when a mobile terminal is in idle mode and moves from a first location area to a second location area, the mobile terminal detects that a different Location Area identity (LA ID) (from that stored in the mobile terminal) is being broadcast by the local base station / AP. The mobile terminal then sends a location area update request to the core network 12 / MME. The request includes the first (current) LA ID and the mobile terminal's current Temporary Mobile Subscriber Identity (TMSI). The MSC / MME with which the mobile terminal is currently registered then sends a new TMSI to the mobile terminal 1. When the mobile terminal moves from a first (current) location area to a second location area, and the second location area is administered by a different MSC / MIME, similar steps occur and in addition the diff...

second embodiment

[0096]According to the invention, APs are excluded from the predefined location areas / tracking areas (LAs / TAs) configured by the operator. By excluding the APs from the TAs it is possible to control a UE's ability to access the APs. The Tracking Areas are hence restricted to base stations in the macro-layer.

[0097]Therefore according to this second embodiment of the invention, the APs are not given a LA ID / TA ID or their LA ID / TA ID is set to “null”. Each AP in this embodiment only broadcasts its Cell ID, and not a unique LA / TA ID. Since the APs only have a unique cell global identity, the UEs do not consider them to be accessible merely by virtue of the information broadcast. Therefore, by virtue of not broadcasting a TA ID, the UEs will not consider the AP as a possible point of access; further information needs to be acquired by the UE before the AP will be considered a possible point of access. In other words, since there is no unique LA / TA ID information, the UE will initially t...

Abstract

A GSM, UMTS or LTE mobile telecommunications network includes a radio access network comprising base stations, and further includes one or more additional access points. An access point may be connected to the network core by an IP transport broadband connection. The access point is configured to appear to the mobile terminal as a base station. Arrangements are disclosed which allow the network to restrict access to the network via these access points whilst also minimizing signaling requirements. The access points may be excluded from traditional Tracking Areas, but associated therewith by a network controller in a mapping in order to notify authorized mobile terminals of the Access Point's existence.

Description

TECHNICAL FIELD[0001]This application relates to a telecommunications network including a radio access network for wirelessly transmitting between a mobile telecommunications device and a base station. This application also relates to a method and arrangement for controlling communication access of a mobile device to one or more base stations, and further relates to a system and method for reducing paging in a mobile telecommunications network and in particular to a system and method for reducing the paging of a mobile terminal with the mobile is camped on an access point / femto-cell.BACKGROUND[0002]When a calling party (whether a subscriber within the mobile telecommunications network or outside it) attempts to call a mobile terminal within the network, that mobile terminal must be paged. Paging is a process of broadcasting a message which alerts a specific mobile terminal to take some action, such as to notify the terminal that there is an incoming call to be received.[0003]The arc...
