Method and apparatus for assigning a logical address in a communication system
First Claim
1. A method for assigning a logical address by a master base station to a mobile station in a cloud cell of a wireless communication system comprising the master base station and at least one slave base station serving the mobile station, the method comprising:
- selecting, by the master base station, a unique logical address from a set of logical addresses associated with the master base station, the set of addresses being derived from a common address space comprising a plurality of logical addresses;
assigning, by the master base station, the unique logical address to the mobile station for communicating with the master base station and the at least one slave base station;
notifying, by the master base station, the at least one slave base station of the assignment of the unique logical address to the mobile station;
transmitting, by the master base station, the unique logical address assigned to the mobile station to a new base station being added to the cloud cell; and
receiving, at the master base station, a notification associated with the unique logical address assigned to the mobile station from the new base station and adding the new base station to the cloud cell as a slave base station serving the mobile station based on the notification,wherein each of the master base station and the at least one slave base station is assigned a different set of logical addresses derived from the common address space, andwherein logical addresses included in the different set are determined based on the number of base stations located adjacent to each other in a predetermined area and identifiers of the base stations located adjacent to each other in the predetermined area.

20. A base station for assigning a logical address to a mobile station in a cloud cell of a wireless communication system comprising the base station and at least one slave base station serving the mobile station, the base station comprising:
-
a communication interface configured to communicate with the at least one slave base station; a transceiver configured to communicate with the mobile station; and a processor configured to; select a unique logical address from a set of logical addresses associated with the base station, the set of addresses being derived from a common address space comprising a plurality of addresses, assign the unique logical address to the mobile station for communicating with the base station and the at least one slave base station, notify the at least one slave base station of the assignment of the unique logical address to the mobile station, transmit the unique logical address assigned to the mobile station to a new base station being added to the cloud cell, and receive, at the base station, a notification associated with the unique logical address assigned to the mobile station from the new base station and adding the new base station to the cloud cell as a slave base station serving the mobile station based on the notification, wherein each of the base station and the at least one slave base station is assigned a different set of logical addresses derived from the common address space, and wherein logical addresses included in the different set are determined based on the number of base stations located adjacent to each other in a predetermined area and identifiers of the base stations located adjacent to each other in the predetermined area.
