Method for assigning a unique identifier to a mobility management entity and for implementing a mobility management entity in a core network of an SAE/LTE communication system as well as a mobility management entity

[0059]Advantageous examples of mobility management entities MME1, MME2, MME3 according to the invention are shown in FIGS. 1 and 2.

[0060]FIG. 1 shows schematically a part of a core network CN of an SAE / LTE communication system, with a configuration database O&S and three mobility management entities MME1, MME2, MME3 according to the invention. The mobility management entities are connected to one another via so-called open S11 interfaces, so that each mobility management entity can communicate with all other mobility management entities. Data can be exchanged via open S11 interfaces, which is indicated by the reference number 1.

[0061]In addition to the S11 interfaces, the mobility management entities MME1, MME2, MME3 each have an interface S12 to a configuration database O&S. The S12 interfaces serve for constructing a connection to the configuration database O&S and for transmitting data to and from the configuration database O&S. Each mobility management entity MME1, MME2, MME3 fur
