1. A method for managing MME loading, comprising:
- monitoring indicia of eNodeB loading at a source MME; and
in response to said loading indicia exceeding a policy-defined threshold level, migrating responsibility for one or more eNodeBs to a target MME.

18. An apparatus for managing MME loading, the apparatus comprising:
-
a processor configured for; monitoring indicia of eNodeB loading at a source MME; and in response to said loading indicia exceeding a policy-defined threshold level, migrating responsibility for one or more eNodeBs to a target MME, said migrating comprising; transmitting to the target MME a message adapted to cause the target MME to form links to the eNodeBs to be migrated; converting existing links between the eNodeBs to be migrated and the source MME to standby links; transmitting to the target MME state information associated with the eNodeBs to be migrated; and preventing the acceptance of new services at the source MME associated with the eNodeBs to be migrated.

19. A computer readable storage medium storing instructions which, when executed by a computer, cause the computer to perform a method for managing MME loading, comprising:
-
monitoring indicia of eNodeB loading at a source MME; and in response to said loading indicia exceeding a policy-defined threshold level, migrating responsibility for one or more eNodeBs to a target MME, said migrating comprising; transmitting to the target MME a message adapted to cause the target MME to form links to the eNodeBs to be migrated; converting existing links between the eNodeBs to be migrated and the source MME to standby links; transmitting to the target MME state information associated with the eNodeBs to be migrated; and preventing the acceptance of new services at the source MME associated with the eNodeBs to be migrated.

20. A computer program product wherein computer instructions, when processed by a computer, adapt the operation of the computer to provide a method for managing MME loading, comprising:
-
monitoring indicia of eNodeB loading at a source MME; and in response to said loading indicia exceeding a policy-defined threshold level, migrating responsibility for one or more eNodeBs to a target MME, said migrating comprising; transmitting to the target MME a message adapted to cause the target MME to form links to the eNodeBs to be migrated; converting existing links between the eNodeBs to be migrated and the source MME to standby links; transmitting to the target MME state information associated with the eNodeBs to be migrated; and preventing the acceptance of new services at the source MME associated with the eNodeBs to be migrated.
