Claim 8:
9. A method for improving availability of a type of network element in a mobile network, the method being implemented by at least one networking device that interconnects a first source network element and a network element anycast set, 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 the first source network element, the first message being addressed to an anycast set address that is associated with the network element anycast set;
routing the first message along a first path that leads to the first network element instance, the routing being based at least in part on a routing policy;
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;
determining that the first network element instance is unavailable;
receiving a second message from the first source network element when the first network element instance is unavailable, the second message being addressed to the anycast set address;
routing the second message along a second path that leads to the second network element instance based at least in part on the routing policy; 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.
