  • This part comprises SGSNs (serving GPRS Support Node) and MMEs (mobile management entities) entities 56 and 58.
  • the mobile packet core 34 may comprise a function 60. This function may provide one or more of a lawful intercept function which allows authorised authorities to monitor communications, policy control function and charging control function.

  • QoS scheduling strategies use both service and subscriber information in order to select the scheduling priorities (SPI) for data transmissions over the radio interface.
  • SPI scheduling priorities
  • the SPI will control will control the scheduling priority of a data transmission.
  • Some embodiments may provide a QoS scheduler that may take into account cell congestion information and/or application information. This may improve the SPI selection and corresponding resource allocation for UE data transmission.
  • Table 2 Extended QoS attributes mapping table
  • radio information is used for SPI and NBR selection.
  • the radio information may comprise one or more of cell load and radio link (RL) quality.
  • An intermediate case, between the above two cases, is where the cell load is greater than a minimum threshold value and the radio link quality is greater than a maximum threshold, the NBR will be 512kbps and the SPI will be 1 1 ,
  • the SPI may be desirable to select the SPI not only based on the radio conditions, but also on the file size. This way, larger file sizes can be given higher priority in order to speed up their downloading times. It can be further boosted by even providing a higher NBR value depending on the above mentioned conditions. For example, if the file size is relatively large then a higher SPI and NBR will be used as compared to if the file size is medium. A still lower SPI may be used for a smaller file with a best effort bit rate. Alternatively or additionally, for a larger file size a smaller SPI may be used if the cell load is greater than a maximum threshold. Alternatively or additionally a larger SPI may be used for a smaller file size of the cell load is less than a cell load minimum threshold.

The offload router and in particular the offload function 312 will control the routing of those packets. In some embodiments, the offload routing function 312 may route information from applications to the radio access network or back to the gateway.
