Claim 16:
17. A system for improving availability of a type of network element in a mobile network, the system comprising:
one or more processors;
memory in electronic communication with the one or more processors;
an anycast address stored in the memory, the anycast address being assigned to a network element anycast set comprising a first network element instance and a second network element instance;
an anycast set data store within a core network of the mobile network, the anycast set data store being associated with the network element anycast set and accessible to the first network element instance and the second network element instance; and
instructions stored in the memory, the instructions being executable by the one or more processors to:
receive a first message from a first source network element at the first network element instance, wherein the first message is addressed to the anycast address;
process the first message by the first network element instance;
access, by the first network element instance, state information corresponding to a user equipment from the anycast set data store in relation to processing the first message;
receive 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;
process the second message by the second network element instance; and
access, 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.
