Abstract
Some demonstrative embodiments include devices, systems and/or methods to establish a connection to the Internet via a local gateway (L-GW) function for a LIPA or a SIPTO@LN. The establishment of the connection to the Internet may be performed, for example, by at least one of an E-RAB SETUP procedure, an INITIAL CONTEXT SETUP procedure, an INITIAL UE MESSAGE procedure or an UPLINK NAS TRANSPORT procedure.
Claims4
An evolved NodeB (eNB), comprising:
- a processor;
- and
- a communication module, coupled to the processor, to:
- transmit an initial user equipment (UE) message to a Mobility Management Entity (MME) before forwarding a first uplink non-access stratum (NAS) message, wherein the initial UE message comprises a selected Internet Protocol (IP) traffic offload (SIPTO) local gateway (L-GW) transport layer address based on the eNB support of SIPTO at local network (SIPTO@LN) function for an Internet access through a local network,
- wherein the SIPTO L-GW transport layer address is to indicate that a SIPTO L-GW collocates with the eNB.
