Abstract:
The present invention proposes methods, devices and computer program products in relation to enhancements for providing for RAN based LGW selection. Two basic options for the RAN based improved solution are presented for scenarios in which HeNB sends a list of the available LGW addresses/identities and the APNs supported by the different LGWs. According to option 1, if more than one LGW can support a given APN, then the H(e)NB only sends the address of the preferred LGW (e.g., based on local network topology) for the given APN. According to option 2, the HeNB sends priority value (s) with the addresses of the LGWs (for the LGWs only (irrespective of supported APNs) or for (only) the APNs supported by each LGW. Then, the MME/SGSN may consider this priority value (s) at the LGW selection.
