5  Support of Localised Service Area (SoLSA)p. 25

SoLSA consists of a set of service features that give the operator a basis to offer subscribers different services (e.g. tariffs or access rights) depending on the location of the subscriber (TS 42.043). The following section is only applicable to the support of SoLSA functionality in GERAN.

5.1  Network selectionp. 25

The standard automatic and manual network selection procedures will be used.
Manual network selection may be required when the PLMN providing the users SoLSA service is not the one on which the user is currently registered.
At manual network selection the UE shall provide the means to present the subscribers LSA(s) for each PLMN presented.

5.2  The Idle-mode operationp. 25

The UE shall always select a valid LSA with the highest priority.

5.2.1  Subscriber moving from a normal environment to his localised service areap. 25

The UE shall have the ability to prioritise allowed LSA cells in reselection, making it possible to camp on a LSA cell earlier (the function shall be network controlled).

5.2.2  Subscriber moving away from his localised service area to a normal environmentp. 25

The UE shall have the ability to prioritise allowed LSA cells in reselection, making it possible to camp on a LSA cell longer (the function shall be network controlled).

5.2.3  Subscriber staying in his localised service areap. 25

The UE shall have the ability to prioritise allowed LSA cells in reselection by being more persistent (the function shall be network controlled).

5.3  LSA only accessp. 26

It shall be possible to allow LSA user to access PLMN only within his LSAs. A LSA user is not allowed to receive and/or originate a call outside the allowed LSA area.
When UE is out of the allowed LSA area it shall be registered in PLMN but indicate subscriber/service specific "out of LSA area" notification. It shall be a network-controlled function to prevent terminated or/and originated calls. Emergency calls are however always allowed.

5.4  Exclusive accessp. 26

Access to exclusive access cells is restricted to defined LSA subscribers.
Non-LSA subscriber shall consider exclusive access cells as not suitable, only allowing to camp for emergency calls (limited service state TS 23.122).

5.5  Preferential accessp. 26

As a network-controlled function, it shall be possible in LSA to allocate resources at call setup and during the active mode to LSA users compared to non-LSA users.

6  Support of 3GPP - WLAN Interworking |R6|p. 26

Support of 3GPP-WLAN interworking and network selection is captured in TS 22.234
