1. A method comprising:
- establishing a first radio connection between a first cell and a user equipment (UE);
determining a network identity of a second cell based on a first set of at least one network identity associated with the first cell, wherein the second cell is associated with a second set of at least one network identity, the determined network identity useable for establishing a second radio connection between the second cell and the UE, and wherein determining the network identity of the second cell comprises identifying a network identity in the second set that is common with a network identity in the first set;
sending, by a wireless access network node of the first cell to the UE, a list that includes one or more network identities that are common between the first set and the second set; and
receiving, by the wireless access network node from the UE, a selection of a network identity from the list.

Abstract
A first radio connection is established between a first cell and a user equipment (UE). A network identity of a second cell is determined based on a first set of at least one network identity associated with the first cell, where the second cell is associated with a second set of at least one network identity. The determined network identity is useable for establishing a second radio connection between the second cell and the UE.

3. An article comprising at least one non-transitory machine-readable storage medium storing instructions that upon execution cause a wireless access network node of a first cell to:
-
establish a first radio connection between the first cell and a user equipment (UE); receive, from the UE, a network identity of the first cell selected from a first set of at least one network identity associated with the first cell; and determine a network identity of a second cell based on the received network identity of the first cell, wherein the second cell is associated with a second set of at least one network identity, the determined network identity useable for establishing a second radio connection between the second cell and the UE. - View Dependent Claims (4, 5)
