A method and apparatus for detecting recovery of an interrupted cell, including: transmitting request access information to a coverage of an interrupted cell by a base station of the interrupted cell after performing a self-healing process, so that user equipment within the coverage accesses to the base station according to the request access information; counting, by the base station, whether there is user equipment succeeded in accessing within a predefined period of time, or counting whether the number of user equipments succeeded in accessing within a predefined period of time is greater than a predefined threshold value; and determining by the base station that the interrupted cell is recovered, if there is user equipment succeeded in accessing within the predefined period of time, or if the number of user equipments succeeded in accessing within the predefined period of time is greater than the predefined threshold value.. .
|Logical address assignment in a cloud cell|
A method and system for assigning a unique logical address in a cloud cell having a mobile station, slave base stations and a master base station are provided. The method includes determining at least one unassigned logical address from respective address spaces associated with the slave base stations and the master base station in the cloud cell by the master base station, selecting the unique logical address from the at least one unassigned logical address determined from the respective address spaces associated with the plurality of base stations, and assigning the selected unique logical address to the mobile station in the cloud cell.
|Method and apparatus for security communication of carrier aggregation between base stations|
This invention discloses a method for security communication of carrier aggregation between base stations, which method comprises receiving, by a user equipment, a first message to add a cell controlled by a secondary base station as a service cell sent by a primary base station; and creating, by the user equipment, a security key for communication with cells controlled by the secondary base station according to security context of the primary base station and the first message. This invention further discloses the corresponding user equipment and base stations.
|Method for generating a congestion flag based on measured system load|
A radio base station generates a congestion status flag, based on measured resource usage in its cell, and based on performance of sessions in the cell. The flag may be a one bit, or a small number of bits, indicating whether the base station is congested.
|Network diagnostic system for analyzing performance of a radio network during functional over-the-air operation|
An apparatus determining network health in a network comprising base station transceivers in bidirectional communication with radios, each having an identifier and transmitting a signal including the identifier. First and second devices each receive the transmitted signal during normal over-the-air operation of the radio, measure signal parameters, and determine operating characteristics of the radio from the parameters.
