The controller assigns a temporary identification to the user equipment and sends a modified attach request including the temporary identification, and application server identification and an application server IP address to the radio access network access point. The controller configures a forwarding table associated with the radio access network access point so that the access point forwarding table matches the user equipment identification, the application server identification and the application server IP address. The controller configures a service edge creation environment function forwarding table so that the forwarding table matches the user equipment identification mapped to the radio access network access point IP address and instructs an action so that packet traffic to and from the user equipment is processed without an explicit connection oriented signaling protocol. ## Claims ### Claim 1 A method for processing a request for services by a user equipment (UE) comprising: receiving at a software defined network controller from a radio access network (RAN) access point (AP) an attach request generated by the UE; assigning a temporary identification (Temp ID) to the UE; sending a modified attach request to the RAN AP wherein the modified attach request includes the Temp ID; and configuring a service edge service creation environment function (SE/SCEF) forwarding table, whereby the SE/SCEF forwarding table instructs an SE/SCEF action whereby packet traffic to and from the UE is processed without the requirement of a tunnel. ### Claim 2 (depends on 1) The method of claim 1, further comprising authenticating the attach request. ### Claim 3 (depends on 1) The method of claim 1, further comprising authenticating the attach request comprises: sending an authentication request including a UE identification to an authentication server; and receiving an authentication response from the authentication server, wherein the authentication response comprises the UE identification, an application server identification, or an application server internet protocol (IP) address. ### Claim 4 (depends on 3) The method of claim 3, wherein the UE identification comprises an International Mobile Subscriber Identity, an International Mobile Equipment Identity, or an integrated circuit card identifier. ### Claim 5 (depends on 1) The method of claim 1, wherein the UE is an internet of things device. ### Claim 6 (depends on 1) The method of claim 1, further comprising adding a first routing tag and forwarding packets to an AP output port. ### Claim 7 (depends on 1) The method of claim 1, wherein the SE/SCEF action is to add a second routing tag and forwarding packets to an SE/SCEF output port. ### Claim 8 A system for processing a request for services by a user equipment (UE) comprising: one or more processors; and memory coupled with the one or more processors, the memory storing executable instructions that when executed by the one or more processors cause the one or more processors to effectuate operations comprising: receiving at a software defined network controller from a radio access network (RAN) access point (AP) an attach request generated by the UE; assigning a temporary identification (Temp ID) to the UE; sending a modified attach request to the RAN AP wherein the modified attach request includes the Temp ID; and configuring a service edge service creation environment function (SE/SCEF) forwarding table, whereby the SE/SCEF forwarding table instructs an SE/SCEF action whereby packet traffic to and from the UE is processed without the requirement of a tunnel. ### Claim 9 (depends on 8) The system of claim 8, wherein the operations further comprising authenticating the attach request. ### Claim 10 (depends on 8) The system of claim 8, the operations further comprising authenticating the attach request comprises: sending an authentication request including a UE identification to an authentication server; and receiving an authentication response from the authentication server, wherein the authentication response comprises the UE identification, an application server identification, or an application server internet protocol (IP) address. ### Claim 11 (depends on 10) The system of claim 10, wherein the UE identification comprises an International Mobile Subscriber Identity, an International Mobile Equipment Identity, or an integrated circuit card identifier. ### Claim 12 (depends on 8) The system of claim 8, wherein the UE is an internet of things device. ### Claim 13 (depends on 8) The system of claim 8, further comprising adding a first routing tag and forwarding packets to an AP output port. ### Claim 14 (depends on 8) The system of claim 8, wherein the SE/SCEF action is to add a second routing tag and forwarding packets to an SE/SCEF output port. ### Claim 15 A non-transitory computer-readable storage medium storing computer executable instructions that when executed by a computing device cause said computing device to effectuate operations comprising: receiving at a software defined network controller from a radio access network (RAN) access point (AP) an attach request generated by the UE; assigning a temporary identification (Temp ID) to the UE; sending a modified attach request to the RAN AP wherein the modified attach request includes the Temp ID; and configuring a service edge service creation environment function (SE/SCEF) forwarding table, whereby the SE/SCEF forwarding table instructs an SE/SCEF action whereby packet traffic to and from the UE is processed without the requirement of a tunnel. ### Claim 16 (depends on 15) The non-transitory computer-readable storage medium of claim 15, wherein the operations further comprising authenticating the attach request. ### Claim 17 (depends on 15) The non-transitory computer-readable storage medium of claim 15, the operations further comprising authenticating the attach request comprises: sending an authentication request including a UE identification to an authentication server; and receiving an authentication response from the authentication server, wherein the authentication response comprises the UE identification, an application server identification, or an application server internet protocol (IP) address. ### Claim 18 (depends on 15) The non-transitory computer-readable storage medium of claim 15, wherein the UE identification comprises an International Mobile Subscriber Identity, an International Mobile Equipment Identity, or an integrated circuit card identifier. ### Claim 19 (depends on 16) The non-transitory computer-readable storage medium of claim 16, wherein the UE is an internet of things device. ### Claim 20 (depends on 16) The non-transitory computer-readable storage medium of claim 16, wherein the SE/SCEF action is to add a second routing tag and forwarding packets to an SE/SCEF output port.
