Claim of US Patent No. 10,694,568

1. A method of operating a terminal device in a first network, the method comprising:receiving, from the first network, one or more indices and a mapping between the one or more indices and respective network identifiers, each network identifier identifying a network and/or a network node, wherein a network identifier is mapped to an index which is common for one or more network identifiers while also being mapped to an index which is unique to the network identifier;
receiving, from the first network, a communication that specifies a particular index of the one or more indices, wherein the communication includes an instruction to perform a mobility-related action relating to a network and/or network node having the particular index;
determining that two or more networks and/or network nodes share the particular index;
determining which one of the two or more networks and/or network nodes having the shared index the terminal device is to take the mobility-related action relating to;
wherein the mobility-related action comprises sending a report to the first network; and
wherein the step of determining comprises determining the network and/or network node having the shared index to take the mobility-related action relating to as the network and/or network node that has any one or more of:
(i) the strongest signal;
(ii) the highest signal quality;
(iii) the lowest air interface load;
(iv) the highest total capacity; and
(v) the highest current capacity.
