Partial support of mobility between radio access networks
First Claim
1. A method for use in a radio access network of a first operator network having cells which are eligible for utilization by a user equipment unit which is in a connected mode and which subscribes to a second operator network, the method comprising:
- designating as a restricted cell any cell of the first operator network for which the second operator network has a competing cell; and
rejecting attempted utilization by the user equipment unit which subscribes to the second operator network of the restricted cell.

Abstract
Attempted utilization (by a user equipment unit which subscribes to its subscription operator network) of a restricted cell is precluded or rejected by an auxiliary operator'"'"'s network, the restricted cell being any cell of the auxiliary operator network for which a subscription operator network has a competing cell. The rejected attempted utilization can be one of (1) handover to the restricted cell, and (2) cell/URA updating by the user equipment unit via the restricted cell. Further, preclusion of attempted utilization of the restricted cell occurs when the user equipment unit attempts cell reselection.

21. A radio access network of a first operator network having cells which are eligible for utilization by a user equipment unit which is in a connected mode and which subscribes to a second operator network;
- the radio access network comprising;
means for designating as a restricted cell any cell of the first operator network for which the second operator network has a competing cell;
means for rejecting attempted utilization by the user equipment unit which subscribes to the second operator network of the restricted cell. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)

41. A radio access network of a first operator network, the network comprising:
-
at least one base station having a radio frequency signal monitored by a user equipment unit, the user equipment unit being in a connected mode and subscribing to a second operator network;
a control node which controls the at least one base station;
a PLMN filter which rejects attempted utilization, by the user equipment unit which subscribes to the second operator network, of a restricted cell of the first operator network, the restricted cell being a cell of the first operator network for which the second operator network has a competing cell. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74)

58. A control node of a radio access network of a first operator network which rejects attempted utilization, by a user equipment unit which subscribes to the second operator network, of a restricted cell of the first operator network, the restricted cell being a cell of the first operator network for which the second operator network has a competing cell.
- 75. A mobile terminal which subscribes to a native operator network and which, in a connected mode and prior to cell reselection to a target cell, checks whether the target cell is a restricted cell, the restricted cell being both operated by a foreign operator network and competing with a cell operated by the native operator network.
