Abstract: SGSNs in the same pool-area share their resource information by using O&M messages or GTP-C messages. At least one of the SGSNs (Sleeping SGSN) decides to sleep (shut down or run in a low power state), based on the resource information. Then the Sleeping SGSN sends a power down notification to the connected RNC/BSC and SGSNs, thereby preventing the RNC/BSC from selecting the Sleeping SGSN for new connection and handovers, and transferring the load on the Sleeping SGSN to other SGSNs.

Abstract: In order to save energy in EPS network, some of the MMEs and/or S-GWs are allowed to sleep (power down), when network's traffic load is decreased. When the traffic load becomes heavier, the network can power up some of the formerly sleeping MMEs and/or S-GWs.
