A common core network is the only efficient way to handle this situation. Ericsson designed and planned for a common core from the start and our solution has many performance benefits Efficient Capacity Common nodes with node resources shared by GSM WCDMA provide trunking efficiency and futureproof investment. NOTE that some competitor “common core” equipment has independent GSM and WCDMA capacity which severely limits benefits, requiring node re-configuration and hardware write-offs as e.g. 3G traffic grows and 2G traffic falls. Ericsson pool solutions provide complete scalability with simple addition of extra nodes when traffic
