Abstract— Scheduler is the backbone of intelligence in a LTE network. Scheduler will often have clashing needs that can make its design very complex and non-trivial.
The overall system throughput needs to be maintained at the best possible value without sacrificing the cell edge user experience.
In this paper, authors compared different scheduler designs for voice and packet services. They explained the role of configuration parameters through simulations. These parameters control the tradeoff between the sector throughput and the fairness in system through. They explained a possible scheduler implementation.

Consideration of fixed mobile convergence in 5GITU
This presentation will introduce IMT-2020 fixed mobile convergence (FMC) scenarios and requirements, such as service continuity among different access networks in a 5G environment. Based on the requirements, a FMC solution, Unified Network Integrating Cloud (UNIC), will also be introduced, including the high level architecture and some key technologies, such as unified access control for both fixed and mobile, edge computing for user plane, converged subscriber database, Telecom Integrated Cloud (TIC), etc.

Transmission management in BSS is a feature used in managing the Base Station Subsystem transmission system functions such as supervision, alarms, statistics
and settings. The network element mainly responsible for transmission management in BSS is the Base Station Controller (BSC).
Transmission management functionalities make it possible for the operators to manage the transmission equipment remotely from the BSC or from Nokia
NetAct integrated network management system, which simplifies network maintenance and operation. Supervision functions help minimise the time spent in maintenance, and statistics collection helps the operators analyse and optimise
the use of their transmission equipment. Moreover, new software can be downloaded in a way that does not interfere with the traffic.
Hardware and software requirements BSS transmission network elements
BSS transmission management functionalities Transmission parameters Transmission alarms
Transmission measurements
2.Hardware and software requirements
There are no specific hardware or software requirements for the transmission management functionalities. However, the type of the BTS poses certain
limitations.
The BTS type specific functionalities are listed in the table below.
More details about the functionalities can be found in BSS transmission management functionalities .
Polling list sending with priority is a functionality used in positioning. To ensure accurate positioning calculations, the LMU unit must supply Radio Interface Timing System (RIT) information to the network faster than the normal Q1 polling is able to do. Faster LMU polling is achieved by defining a Q1 polling
priority for each Q1 device, with the LMU having the highest priority. For more information see Location Services .
3.BSS transmission network elements
The base Station Subsystem (BSS) consists of at least one Base Station Controller (BSC) and its Base Transceiver Stations (BTS). The Transcoder Submultiplexer
(TCSM) is also part of the BSS although it is actually located in the MSC site. The three basic configurations (topologies) for transmission between the BSC and
the BTSs are: point-to-point connection
multidrop chain multidrop loop
In point-to-point configuration each BTS is connected directly to the BSC. In the multidrop chain, BTSs form a chain and the first BTS in the network is connected directly to the BSC. In the loop connection, the BTSs form a loop where the first and the last BTS in the loop are connected directly to the BSC via a crossconnecting node. The topology used depends on a number of factors such as the distance between the BSC and the BTS, the number of transceivers (TRXs) used at a particular BTS site and the signalling channel rate between the BSC and the\ BTS. Usually the topology used is a mixture of the three basic topologies. Formore information on the topologies, refer to Nokia BSS Transmission\Configuration .
