The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate after 4G communication systems such as LTE. A method according to an embodiment of the present invention is a communication method in a base station which communicates via filter bank-based multicarrier signals. The method may comprise the steps of: performing communication by allocating filters having non-orthogonality with respect to a first terminal positioned within a cell; selecting a filter set from among two or more filter sets having orthogonality with respect to a second terminal positioned at the edge of the cell; and performing communication by allocating, to the second terminal, at least one filter among filters included in the selected filter set.

Some aspects of this disclosure relate to system and methods for a data provider to provide routing data associated with a destination phone number to a service provider. The service provider send a first query to a first computing node of the data provider for routing data associated with a phone number. The first computing node identifies a data provider that is capable of providing the routing data and determines that the routing data is not available locally. The first computing node sends a second query to a second computing node. The second computing node obtains the routing data and returns to the service provider.

A system for bulk telephony control system subscriber data manipulation, comprising an EMU server that receives a plurality of telephony control system subscriber data, analyzes at least a portion of the information, determines whether to modify at least a portion of the telephony control system subscriber data, the determination being based at least in part on the analysis, applies any determined modifications to at least a portion of the telephony control system subscriber data, and provides at least a portion of the information as output, and a method for bulk telephony control system subscriber data manipulation using an EMU server.

A method and a system for dynamic management of allocation of extensions that correspond to directory numbers for a smooth, efficient user experience and operational savings to the allocator is provided. The method includes: receiving, from a user via a user interface such as a telephone terminal, a connect request for an assignment of an extension; analyzing the connect request to determine characteristic traits associated with the user, such as a switch and a physical location; determining a set of available extensions that are assignable to the first user based on the characteristic traits; and assigning, to the user, an extension from within the set of available extensions that has not previously been assigned and that has been prechecked for validity and correct configuration. Upon assignment, the assigned extension is propagated to a ribbon of the user for subsequent usage without needing to reenter the number.

Systems and methods are disclosed to provide routing data associated with a destination phone number to a service provider. The service provider sends a first query to a first computing node of a data provider for routing data associated with a phone number. The first computing node provides the routing data if it is available from the data provider. Otherwise, the first computing node identifies a second data provider that is capable of providing the routing data. The first computing node then obtains the routing data from the second data provider and returns it to the service provider.
