1. A method for improving availability of a type of network element in a mobile network, the method being implemented by a network element anycast set in a core network of the mobile network, the network element anycast set comprising a first network element instance and a second network element instance, the method comprising:
receiving a first message from a first source network element at the first network element instance, wherein the first message is addressed to an anycast address that is assigned to the network element anycast set;
processing the first message by the first network element instance;
accessing, by the first network element instance, state information corresponding to a user equipment from an anycast set data store in relation to processing the first message;
receiving a second message from the first source network element at the second network element instance when the first network element instance is unavailable, wherein the second message is also addressed to the anycast address;
processing the second message by the second network element instance; and
accessing, by the second network element instance, the state information corresponding to the user equipment from the anycast set data store in relation to processing the second message.
