Compared to long term evolution (LTE), the 5th generation (5G) cellular radio access technology (RAT) has aimed at higher peak value According to rate (for example, 10 gigabit per second (GBPS)).But under normal circumstances, about 1 hertz of central processing unit is needed (CPU) it handles to send or receive a bit per second for transmission control protocol/Internet protocol (TCP/IP).For example, 5GBPS Network flow need 5 Gigahertzs (GHz) CPU processing.This means that need 2 of the multi-core processor of 2.5GHz it is complete Kernel handle TCP/IP associated with the TCP/IP flow of 5GBPS processing.

The processing of TCP/IP stack is unloaded to network controller using TCP unloading engine (TOE) in network interface card.Its It is mainly used for high speed network interfaces (for example, gigabit Ethernet and 10 gigabit Ethernets), wherein the processing expense of network stack Become significant.TOE can be used to reduce the application processor of mobile device in next-generation (for example, 5G) cellular network interface Cpu cycle.But the use of TOE will increase the cpu cycle of communication processor (CP), and communication processor is still set in movement It is standby upper, therefore still can consume the resource and power of mobile device.

The some aspects of subject technology are solved in computer or cellular technology field and are reduced at user equipment (UE) TCP/IP handles the problem of (and resource and battery utilization).According to some embodiments, which includes TCP/IP unloading framework and by TCP/IP stack be unloaded to outside UE to be unloaded to completely service eNode B (eNB) or The necessary air interface of WiFi access point (AP) changes.Some embodiments support TCP flow amount and User Datagram Protocol (UDP) both flows.

In the document, LTE proprietary term (for example, UE, eNB etc.) can be used identify the node in LTE network and The node of logic or ideational function that can be similar with LTE nodes sharing in other networks.

As a kind of operating principle, some embodiments may include allowing eNB to represent UE and establish TCP or UDP to connect and shine Care for all TCP/IP processing for connection.As a result, UE directly handles the set of original application data or the operating system from UE Connect the data of word and connection manager.

Some TOE solutions by TCP/IP processing from application processor be unloaded to communication/network processing unit (communication/ Network processing unit is still on UE).For example, TCP function is unloaded to edge cloud by TCP Enabler Proxy solution.But it is this Scheme is based on high-rise (transport layer or application layer that come from open system interconnection (OSI) model) agreement.TCP Enabler Proxy solves Scheme has following limitation: additional retransmissions or coding for reliable delivery of packets and the additional UDP/IP association for tunnel View processing.

The some aspects of subject technology provide the following contents: TCP/IP processing is unloaded to outside UE completely to unload To eNB or AP；Dependent on third generation partner program (3GPP) radio access network (RAN) (LTE) agreement (for example, grouping Data convergence protocol (PDCP)) and radio link control/automatic repeat request (RLC/ARQ) ensure without additional overhead Under the conditions of reliable and orderly delivery of packets；Without additional transport layer or IP layers of (in osi model) protocol processes Under the conditions of directly pass through 3GPP RAN (LTE) agreement (for example, PDCP) transmitting user data；And pass through 3GPP RAN (LTE) Working closely to support the other contents such as end-to-end (e2e) flow control between stack and TCP/IP stack.

Fig. 2A to Fig. 2 B shows example and unloads agreement (RTOP) stack based on the TCP/IP of RAN, wherein Fig. 2A shows u Plane, Fig. 2 B show c plane.

As shown in Figure 2 A, in u plane, UE 210A is connected to eNB 220A via Uu interface.UE 210A is in structure Similar to the UE 110A of Figure 1A, and neighbouring TCP/UDP and IP layers, in PDCP layers or more, App layers or less RTOP-u layers of addition. ENB 220A includes RTOP-u layers.RTOP-u layers are (1) PDCP layer in sequence, rlc layer and PHY/MAC layers below, with And the TCP/UDP layer of (2) in sequence and IP layers.PDCP layers TCP/UDP layers neighbouring, IP layers of neighbouring rlc layer and PHY/MAC layers.

As shown in Figure 2 B, in c plane, UE 210B is connected with eNB 220B via Uu interface.UE 210B is similar to UE 110B, wherein RTOP-c layers above rrc layer.ENB 220B is similar to eNB 120B, and RTOP-c layers above rrc layer.

Figure 1A to Figure 1B shows the ICP/IP protocol stack in LTE system, and Fig. 2A to Fig. 2 B shows proposed RTOP Stack.As shown in Figure 1A to Figure 1B and Fig. 2A to Fig. 2 B, the RTOP framework proposed influences access but does not influence core.Such as Fig. 2A To shown in Fig. 2 B, in UE and eNB the two, new RTOP layer is added above PDCP, for the TCP/IP of UE to be handled unloading To eNB.

The some aspects of subject technology include enhancing PDCP with new RTOP layer interface.In some schemes, PDCP quilt Be designed as only with IP layer interface, as shown in Figure 1A to Figure 1B.But as shown in Fig. 2A to Fig. 2 B, in the RTOP framework proposed In, TCP/IP stack is operated on PDCP in a manner of being similar to shown in Figure 1A to Figure 1B.In some cases, RTOP-u function It can be integrated in PDCP, and RTOP-c function is integrated in RRC.In such cases, it does not need in honeycomb RAN agreement New layer (RTOP) is introduced in stack.

On the other hand, the RTOP scheme proposed is only operated after UE is attached, and (is divided existing carrying Group data network (PDN)) establishment process do not influence.As in LTE is netted, UE keeps packet gateway (P-GW) to distribute to it IP address.

In addition, the eNB will own when effective RTOP session (due to any) of UE services eNB by it and terminates The status information of related TCP/IP connection is transmitted back to UE, so that these TCP/IP connections continue without interruption.

Fig. 3 A to Fig. 3 B shows the example for following 802.11 ethernet standard of Electrical and Electronics Engineers Association (IEEE) RTOP stack, wherein Fig. 3 A shows u plane, and Fig. 3 B shows c plane.

Fig. 4 is the data flow diagram for showing the RTOP communication means 400 of user equipment initiation.As shown, method 400 Including at RTOP (RTOP@UE) 410, the eNB at Apps (APP@UE) 405, the UE at UE RTOP (RTOP@eNB) 415, with And gateway/packet gateway (S-GW/P-GW)) communication between network 420.In alternative embodiments, the set of UE can be used Word and connection manager are connect to replace Apps@UE 405, or eNB can be replaced with AP or other network architecture equipment.

Method 400 starts from operation 425, sends RTOP opening to RTOP@UE410 in operation 425, Apps@UE 405 and asks Ask (RTOP-open-REQ).It includes source address, source port, destination IP, destination port and agreement that RTOP, which opens request, Type.RTOP is opened request to RTOP@UE 410 and evolved packet system (EPS) bearer identifier (ID) is transmitted to RTOP@eNB 415。

Apps@UE 405 sends to RTOP@UE 410 and opens TCP/IP connection or operation TCP/ for requesting eNB to represent UE The RTOP-Open-REQ message of IP connection, RTOP UE 410 are then used for example, RRC information forwards that message to eNB. RTOP-Open-REQ message provides five-tuple flow identification information (source IP address, source port, destination IP address, purpose ground terminal Mouth and protocol type) and for identifying EPS carrying ID (or the radio bearer ID) information for flowing belonging carrying.Such as Fruit TCP (or UDP) connection is opened by UE, then RTOP-Open-REQ message further includes the context and status information of connection, So that eNB, which can represent UE, continues TCP (or UDP) connection.

UE, which is represented, in operation 435, RTOP@eNB 415 opens TCP/IP connection.ENB is beaten based on the stream information that UE is provided Open TCP (or UDP) connection (if necessary).Alternatively, eNB is transported based on the context/state information of the UE connection provided Row TCP (or UDP) connection.If connection is successfully established or runs, eNB sends instruction state (success or failure) and stream ID RTOP-Open-RSP message.Note that eNB generates TCP/IP required for connection is established using the flow identification information that UE is provided Grouping, and be grouped on S1-u interface with the TCP/IP of core net (S-GW/P-GW 420) exchange current.

It is transmitted in operation 440, Apps@UE 405 using app data and is communicated with RTOP@UE 410.RTOP@UE 410 is used The transmission of app data is communicated with RTOP@eNB.RTOP@eNB is communicated using S1-u interface with S-GW/P-GW.Apps@UE 405 is bypassed The TCP/IP stack of UE and directly send uplink (UL) data to RTOP@UE 410, RTOP@UE 410 is using PDCP by UL number According to being transmitted to RTOP@eNB 415.RTOP@eNB 415 adds TCP/IP header, and via S1-u interface by data and TCP/IP Header is sent to S-GW/P-GW 420.On the other hand, eNB 415 is via S1-u interface downlink (DL) data, and examines Its TCP/IP header is looked into determine whether respective streams are RTOP stream.If respective streams are RTOP stream, eNB 415 removes TCP/IP Header, and RTOP@UE 410 is then sent the data on PDCP.RTOP UE 410 then bypasses the TCP/IP stack of UE, By the data forwarding received to Apps@UE 405.

RTOP turn-off request (RTOP-close-REQ) is sent to RTOP@UE 410 in operation 445, Apps@UE 405. RTOP turn-off request and stream ID are transmitted to RTOP@eNB 415 by RTOP@UE 415 together.In operation 450, RTOP@eNB 415 It represents UE and closes TCP/IP connection.The RTOP including stream ID is sent to RTOP@UE 410 in operation 455, RTOP@eNB 415 to close Close response (RTOP-close-RSP).RTOP including stream ID is closed response and is transmitted to Apps@UE 405 by RTOP@UE 410.

Apps@UE 405 issues RTOP-Close-REQ message, to close RTOP session.RTOP-Close-REQ message package Stream ID information is included, and also indicates whether to close corresponding TCP (UDP) connection.In response, eNB 415 close connection (if If request), and issue RTOP-Close-RSP message.Alternatively, eNB is closed (by the distal end connected or other event (examples Such as, switching, RRC release) triggering) RTOP session itself, and then issue RTOP-Close-RSP message.If TCP or UDP flow/connection is still within opening state, then TCP (UDP) context connected and status information are included in by eNB 415 In RTOP-Close-RSP message, UE is allowed to continue TCP (or UDP) connection after RTOP session is closed.

After operation 455, method 400 terminates.It should be noted that method 400 is not only used in 3GPP RAN environment, And it can be used in non-3 gpp RAN environment (for example, Wi-Fi environment).

In some cases, PDCP is designed to only support the IP flow in u plane.Utilize new RTOP function, theme The some aspects of technology will enhance PDCP in terms of following two to support non-IP flow: the PDCP grouping lattice of delivering RTOP grouping Formula；And some PDCP functions (for example, header compress contracting) can skip RTOP grouping.

Fig. 5 shows example PDCP/RTOP packet format 500.As shown, packet format 500 includes PDCP header 510, RTOP header 520 and RTOP payload 530.PDCP header 510 include instruction PDCP grouping be IP grouping or 1 label of RTOP grouping.RTOP header 520 includes 1 byte (eight) field of instruction stream ID.RTOP payload 530 is wrapped Include application (app) data.

The some aspects of subject technology include adding new position in PDCP header to mark and indicate PDCP payload It is IP grouping or RTOP grouping.Each RTOP grouping has RTOP header, wherein the grouping is indicated using 1 byte field The stream ID of belonging stream.

Fig. 6 is shown in evolved universal mobile communication system (UMTS) radio access network (E-UTRAN) from transmission Example flow 600 of the PDCP entity 605 to reception PDCP entity 610.

According to some mechanism, PDCP entity 605 application order number (61) 5 and header-compressed in u plane 620 are sent. Grouping associated with PDCP SDU receives the integrity protection (625) in c plane and is encrypted (630), and PDCP Header is added to grouping (635).Grouping not associated with PDCP service data unit (SDU) has the PDCP for being added to it Header (635).In operation 640, grouping is transferred to reception PDCP reality from PDCP entity 605 is sent on radio interface (Uu) Body.

It receives PDCP entity 610 and removes PDCP header (645) from grouping.For grouping associated with PDCP SDU, answer With the integrity verification (655) in decryption (650) and c plane.For grouping not associated with PDCP SDU, skip operations 650 and 655.Receiving PDCP entity 610, application header decompresses in u plane at operation 660, and in u at operation 665 It is detected in plane using order delivery and repetition.According to some aspects of subject technology, (but IP is not directed to for RTOP grouping Grouping), skip header compression operation 620 and header decompression operation 660.

In short, Fig. 6 shows the header compress contracting (operation 620 and 660) skipped in PDCP for RTOP grouping Function.RTOP is grouped, other PDCP functions remain unchanged.

End-to-end (e2e) flow control is TCP function.Therefore, RTOP is interacted with TCP/IP stack and is supported flow control.In the following, Respectively in connection with Fig. 7 and Fig. 8, DL and UL is separately discussed.Further, it is assumed that PDCP and radio link control (RLC) affirmation mode (AM), to ensure sequentially reliable delivery.
