A method comprising: receiving, by a network node from a user equipment, UE, a registration request comprising: a first indicator configured to indicate a status of emergency information previously received at the UE, wherein the status of previously received emergency information comprises one or more of: a first indication of previously received descriptions of emergency identifiers; and a second indication of previously received emergency identifiers; wherein the first indication is the result of a hashing, by a hashing function, the previously received descriptions of emergency identifiers; and wherein the second indication is the result of hashing, by a hashing function, the previously received emergency identifiers; upon receipt by the network node of the first indication , determining, by the network node, whether the received first indication matches a third indication available at a network; wherein the network node does not include descriptions of emergency identifiers in a registration accept message if the first indication matches the third indication, and wherein the network node includes the descriptions of emergency identifiers in the registration accept message if the first indication does not match the third indication; upon receipt of the second indication, determining, by the network node, whether the received second indication matches a fourth indication available at a network, wherein the network node does not include emergency identifiers in the registration accept message if the second indication matches the fourth indication, and wherein the network node includes the emergency identifiers in the registration accept message if the second indication does not match the fourth indication; and transmitting, from the network node to the UE, the registration accept message. a first indicator configured to indicate a status of emergency information previously received at the UE, wherein the status of previously received emergency information comprises one or more of: a first indication of previously received descriptions of emergency identifiers; and a second indication of previously received emergency identifiers; a first indication of previously received descriptions of emergency identifiers; and a second indication of previously received emergency identifiers; wherein the first indication is the result of a hashing, by a hashing function, the previously received descriptions of emergency identifiers; and wherein the second indication is the result of hashing, by a hashing function, the previously received emergency identifiers; upon receipt by the network node of the first indication , determining, by the network node, whether the received first indication matches a third indication available at a network; wherein the network node does not include descriptions of emergency identifiers in a registration accept message if the first indication matches the third indication, and wherein the network node includes the descriptions of emergency identifiers in the registration accept message if the first indication does not match the third indication; upon receipt of the second indication, determining, by the network node, whether the received second indication matches a fourth indication available at a network, wherein the network node does not include emergency identifiers in the registration accept message if the second indication matches the fourth indication, and wherein the network node includes the emergency identifiers in the registration accept message if the second indication does not match the fourth indication; and transmitting, from the network node to the UE, the registration accept message. <EOS>
