Isolated E-UTRAN operation
It is provided a method, comprising providing a first and a second service to a first a second user by a providing unit; monitoring if the providing unit operates in an isolated mode or in a linked mode; and at least one of a service controlling and a user controlling, wherein the service controlling comprises inhibiting, in the isolated mode, the providing unit from providing the second service to the first and the second user; and preventing that the providing unit is inhibited from providing the first service to at least one user; and the user controlling comprises inhibiting, in the isolated mode, the providing unit from providing the first and the second service to the second user; and preventing that the providing unit is inhibited from providing at least one service to the first user.
1. An apparatus, comprising:
providing means adapted to provide each of a first service and a second service to each of a first user and a second user;
mode monitoring means adapted to monitor if the providing means operates in an isolated mode or in a linked mode opposite to the isolated mode; and
a service control means and a user control means, wherein
the service control means comprises
a service inhibiting means adapted to inhibit, if the providing means operates in the isolated mode, the providing means from providing the second service to at least one of the first user and the second user and providing the first service to at least one of the first user and the second user; and
a service maintaining means adapted to prevent the service inhibiting means from inhibiting the providing means from providing the first service to at least one of the first user and the second user; and
the user control means comprises
a user inhibiting means adapted to inhibit, if the providing means operates in the isolated mode, the providing means from providing the first service and the second service to the second user; and
a user maintaining means adapted to prevent the user inhibiting means from inhibiting the providing means from providing at least one of the first service and the second service to the first user,
wherein a notification that the isolated mode is in operation is broadcast to the first user and the second user in a serving area of a base station.
2. A method, comprising:
providing each of a first service and a second service to each of a first user and a second user by a providing unit;
monitoring if the providing unit operates in an isolated mode or in a linked mode opposite to the isolated mode; and
a service controlling and a user controlling, wherein
the service controlling comprises
inhibiting, if the providing unit operates in the isolated mode, the providing unit from providing the second service to at least one of the first user and the second user and providing the first service to at least one of the first user and the second user; and
preventing that the providing unit is inhibited from providing the first service to at least one of the first user and the second user; and
the user controlling comprises
inhibiting, if the providing unit operates in the isolated mode, the providing unit from providing the first service and the second service to the second user; and
preventing that the providing unit is inhibited from providing at least one of the first service and the second service to the first user,
wherein a notification that the isolated mode is in operation is broadcast to the first user and the second user in a serving area of a base station.
3. The method according to claim 2 , further comprising:
monitoring if a link from the providing unit to a core network is available with at least a predefined quality;
setting the providing unit in the isolated mode if the link is not available with at least the predefined quality.
4. The method according to claim 3 , wherein
the link monitoring comprises continuously monitoring if the link is available with at least the predefined quality; and the method may further comprise
setting the providing unit in the linked mode if the link is available with at least the predefined quality.
5. The method according to claim 4 , further comprising:
providing the first service to the first user without interruption if the providing unit from the isolated mode into the linked mode.
6. The method according to claim 2 , further comprising:
informing at least one of a base station device different from an apparatus performing the method, a third user, and a mobile edge computing device that the providing unit operates in the isolated mode and/or that the providing unit operates in the linked mode.
7. The method according to claim 6 , wherein the third user is informed by broadcasting an isolated mode notification.
8. The method according to claim 2 , wherein the first service is at least one of a group communication service and a proximity service.
9. The method according to claim 2 comprising the service controlling and further comprising:
determining the first service based on a received service determination message.
10. The method according to claim 9 , further comprising:
monitoring if one of the first user and the second user is handed over to a first base station device different from an apparatus performing the method;
forwarding a service indication based on the service determination message to the first base station device.
11. The method according to claim 2 comprising the user controlling and further comprising:
determining the first user based on a received user determination message.
12. The method according to claim 11 , further comprising:
monitoring if one of the first user and the second user is handed over to a second base station device different from an apparatus performing the method;
forwarding a user indication based on the user determination message to the second base station device.
13. The method according to claim 2 performed in a base station apparatus.
14. A non-transitory computer-readable medium comprising program instructions which when executed by a processor causes an apparatus to perform at least the following:
providing each of a first service and a second service to each of a first user and a second user by a providing unit;
monitoring if the providing unit operates in an isolated mode or in a linked mode opposite to the isolated mode; and
a service controlling and a user controlling, wherein
the service controlling comprises
inhibiting, if the providing unit operates in the isolated mode, the providing unit from providing the second service to at least one of the first user and the second user and providing the first service to at least one of the first user and the second user; and
preventing that the providing unit is inhibited from providing the first service to at least one of the first user and the second user; and
the user controlling comprises
inhibiting, if the providing unit operates in the isolated mode, the providing unit from providing the first service and the second service to the second user; and
preventing that the providing unit is inhibited from providing at least one of the first service and the second service to the first user,
wherein a notification that the isolated mode is in operation is broadcast to the first user and the second user in a serving area of a base station.
