Abstract: A method for alleviation of congestion in a mobile communications network includes detecting congested cells in the mobile communications network, identifying subscribers with active data sessions in the congested cells; and optimizing bandwidth usage for at least one of the identified subscribers. A bandwidth optimization system includes a network sampling interface to receive at least subscriber, cell and data session identifiers from a network data packet sampler, where the sampler identifies the identifiers from internal data traffic within a mobile communications network, and a network awareness engine (NAE) to at least cross reference the identifiers with external data traffic output by the mobile communications network to at least detect congested cells and associated subscriber data sessions emanating from the mobile communications network.

Abstract: In a heterogeneous network based on LTE, the random access, RA, procedure triggered in a macrocell produces transmissions from a UE (20) on the physical random access channel, PRACH, which a picocell eNB (12) can attempt to make measurements of for interference coordination purposes over the X2 interface between the macro eNB (10) and the pico eNB (12). By reconfiguring the UE's behavior during principally the contention-free RA procedure, its transmissions on PRACH are made different to the default such as to be suitable for heterogeneous network interference measurements. This is done by assigning new meanings to certain of the characteristic parameters provided by the macro eNB (10) to the UE (20), such as the RA preamble it uses and the C-RNTI it is assigned during the procedure.

When a new voice call (or other communication session) is set up between access terminals in a wireless communication system, a network device, such a base station, can determine a respective maximum coding rate supported on carrier frequencies of both an originating access terminal and a terminating access terminal.
