Method and a system for distributing of user equipment context in an evolved packet system

A method for distributing of user equipment context in an evolved packet system, including

• a plurality of user equipment,
• at least one eNodeB,
• at least a first mobility management entity and a second mobility management entity, and
• at least one serving gateway connected to at least the first and second mobility management entities,
• the plurality of user equipment being connected via one of the eNodeBs to the second mobility management entity and to the at least one serving gateway,
• a user equipment context for each of the plurality of user equipment each being stored at the second mobility management entity, the method comprising:
• a) transferring in bulk all user equipment contexts of the plurality of user equipment contexts stored at the second mobility management entity to the first mobility management entity within a first transfer time, each user equipment context including, for each user equipment, a mobility management entity code;
• b) reconfiguring the mobility management entity codes by and in the first mobility management entity;
• c) storing said transferred user equipment contexts of the plurality of user equipment in the first mobility management entity;
• and
• d) transferring the reconfigured mobility management entity codes to the at least one eNodeB.
