1. A method, comprising:
at a user equipment having at least two connections to at least two network nodes, where each connection corresponds to a different user identity, wherein each user identity is determined using at least a subscriber identity module;
receiving by the user equipment and from one or both of the network nodes a maximum allowed unavailable time;
selecting by the user equipment one of the at least two network nodes to communicate exclusively with during one or more time intervals; and
sending by the user equipment one or more messages toward the other ones of the at least two network nodes, the one or more messages indicating to the other ones of the at least two network nodes that the user equipment is unavailable for communication during the one or more time intervals,
wherein the one or more time intervals for another one of the least two network nodes are indicated using a function that converts from one time frame from one network node to another time of another network node to address time drift in communications by the user equipment with the one network node and the other network node.
