M329296 VIII. New description: [New technical field] This creation is related to a wireless communication system. More specifically, the present invention relates to an additional multi-bearer service based on pre-configured data stored in WTRUs in a Long Term Evolution (LTE) General Packet Radio Service (GPRS) Tunneling Protocol (GTP) based system. The synchronization starts. [Prior Art] Figure 1 shows a conventional GPRS (or third generation (3G) wireless communication system) architecture 100 showing various interfaces (or protocols) and user data transmission interfaces between various network entities. The wireless communication system 100 includes at least

A Serving GPRS Support Node (SGSN) 105 and at least one Gateway GPRS Support Node (GGSN) 110. The wireless communication system 1 further includes a Universal Terrestrial Radio Access Network (UTRAN) 115 including one or more Radio Access Networks (RANs), Base Station Systems (BSS), and Radio Network Controllers (RNCs). ) (not shown). The system 1 also includes a plurality of wireless transmit/receive units (WTRUs) 120, each of which includes a coupling

To the terminal device (TE) 125 of the mobile terminal (MT) 130. Allows multi-level mobility by anchoring an Internet Protocol (IP) session at GGSN 110 and by supporting mobility and management protocols for IP and non-IP traffic (or services) provided by SGSN ω5 Promote the wireless communication system 丨 (8) mobility. Figure 2A shows how a dual tunnel is established in the conventional wireless communication system 1 of Figure 1 to provide connectivity for user plane traffic. As shown in FIG. 28, a M329296 GPRS Tunneling Protocol (GTP) User Plane (GTP_U) tunnel 220 is established between the GGSN 205 and the SGSN 210, and a second user plane tunnel 225 is at the SGSN 210 and the Radio Network Controller (rnc). Established between 215. Both tunnels are dedicated to the same user. The GTP tunnel 22 has a user plane and a control plane. The user tunnel 225 is an Ip track with a user plane and a RAN application portion (ranAP) control plane for controlling message delivery. Figure 3 shows a System Architecture Evolution (SAE) of a Long Term Evolution (LTE) based network with various interfaces (or protocols) and user data transmission interfaces between various network entities. The wireless communication system 300 includes an evolved packet core 305' that includes at least one mobility management entity (MME) (or user plane entity (UPE)) 31 and at least one access point 315 between access systems (AS). The anchor point 315 is also referred to as an access track (AGW). The ship type radio access network 32A includes at least one evolved Node B (eNodeB). The wireless communication system 3 further includes a GPRS core 325 as described above with reference to FIG. 1, including at least one universal terrestrial radio access network (UTRAN) 330 and at least one GpRS enhanced data rate for use in a global mobile communication system (GSM) edge radio access network (GERAN) 335. Promote the WTRU in the wireless ventilation system 300 by selling the network protocol (ip) session at the AGW 315 and providing the WTRU through the domain AGW 315. (4) Promote the WTRU in the wireless ventilation system 300 (not shown) Out) mobility. ° LTE-based network is generated from all network operators (AipN) from the network operator, such as instant messaging _ Ip New Zealand and non-third M329296 Generation Partnership (3GPP) IP services (ie wireless region Network (WLAN) traffic is misrouted and routed through the AGW 315. One goal in LTE is to promote mobility and reduce development costs by anchoring IP sessions at the AGW and allowing multi-level mobility and support for existing GpRS (or 3g MM) protocols. In LTE, most services and applications are moved to IP-based platforms. This mobility requires IP connectivity and the resulting traffic is not terminated at the Mobile Management Entity (MME) (or User Plane Entity (UPE)) as it would in GPRS. The current Packet Data Protocol (PDP) context initiation performed in GPRS and Universal Mobile Telecommunications System (UMTS) 3GPP systems is dedicated to a single bearer service. The primary PDP context initiates the execution of the IP configuration and access point name (APN) selection associated with the Session Initiation Protocol (SIp) signaling mode. Each additional bearer service requires a secondary PDP context to start. This means that the three-way signal exchange program will repeat every additional service (such as email, data stream, web browsing, etc.) to be activated. It is therefore necessary to simplify the method by reducing the number of PDP (primary and secondary) starts of the transmitted signal and to increase setup time to perform any of the services mentioned above. [New content] This creation relates to a method of starting a multi-bearer service in an LTE wireless communication system including multiple bearers. At least one of the multi-bearers is initiated during the initial add-on, which incorporates the add-on two to initiate the PDP context initiator. In one embodiment, the LTE add-on is implemented for multi-bearer service initiation, which establishes LTE direct GTp M329296 on-channel or general GPRS GTP dual-pilot operation. In another embodiment, the initial add-on is used to initiate a preset PDP context, which is followed by a modified pDp context for multi-bearer service initiation. These procedures can be used to establish modified LTE Direct GTp or conventional GTP. Double tunnel operation. This creation changes the existing GPRS program by performing a single step of initiating multiple bearers during the initial add-on procedure or by using the initial additional county starter bearer, followed by a modification procedure to initiate the remaining multi-bearer in a single-step. [Embodiment] Field & timely, the term "wireless transmitting/receiving unit (WTRU), including, not limited to user equipment (10)), mobile station, fixed or mobile unit pager, cellular telephone, personal digital assistant (pda), any other type of user equipment that is capable of operating in a wireless environment. As mentioned below, the term "base station, including but not limited to eNodeB, site control (four), access point (Ap) or (d) Any other type of peripheral device operating in a wireless environment. Features of the present work can be incorporated into an integrated circuit (IC) or configured in a circuit comprising a plurality of interconnected components. According to this creation, Lang's lack of a ιρ session at the local GGSN and allows for the MM, and mobile, and the existing MM agreement to support non-traffic/services provided by the SGSN to promote mobility in the Simplified (v) or above system. Figure 2B shows a single user plane track method in accordance with the present authorisation. A single M329296 user plane tunnel 260 is used to reduce the delay and processing power of the MME/upE 255. In the dual tunneling method shown in FIG. 2A, the SGSN 21 (U^, the GTP of the RNC 215 is along with the track 220 and the user plane is 225, which means that the SGSN 210 decodes the packets propagating in both directions and puts them Converted into a different protocol format for the two tunnels 220 and 225. In the single-tunnel approach shown in Figure 2β, the MME/UPE 255 is via two separate interfaces.

(or agreement) (RANAP-C and GTP_C) only establish a tunnel between AGW265 and eNodeB 250. In the single tunneling method, MME/upE255 is not involved in the user plane §fl. Therefore, the user traffic passes through the MME/UPE 255 in both directions without change (i.e., no change). Only eN〇deB 25〇 and AGW 265 are allowed to perform (or act on) user plane traffic. The MME/UPE255 X manages user-related control services including MM, Routing Area Update (RAU), and the like, and its p-based services. The MME/UPE 255 connects the eN〇deB 25A and the AGW 265 using the GTP control plane of the AGW 265 if and the raNAP control plane communicating with the eNodeB 250. When switching between eNodeBs, the MME/upE 255 negative provides new eN〇deB Tunnel Endpoint Identification (TEID) information to the AGW 265 and establishes a single tunnel 260. Figure 4 shows a tunneling protocol for the prior art according to the prior art GPRS protocol. The GTP_U tunnel transmits (i.e., tunnels) user profiles between UTRAN (including, BSS and) and 3G-SGSN, and between 3G-SGSN and 3G_GGSN. Figure 5 shows a tunneling protocol stack according to the present creation, in which a plane tunnel is established between the eNodeB and the AGW. The M329296 IP tunnel shown in Figure 5 can be a GTP-based tunnel or any general purpose IP tunnel. In a preferred embodiment, a GTP-U tunnel is used as an ip tunnel. Figure 6 is a conventional signal pattern diagram of a single tunnel setup procedure. The single tunnel function reduces the delay and processing power at the SGSN by reducing the need for protocol conversion between the RNC and GGSN interfaces and by enabling direct user plane tunnels between the RAN/RNC and the GGSN in the Packet Switched (PS) domain. However, the single tunnel approach will not eliminate the need for an SGSN that manages control traffic for IP-based traffic. The SGSN is still required to control the flat signal mode, MM and call (or session management), and the SGSN determines whether to establish a single track or establish a dual track.

In the case of a single tunnel, the SGSN connects the RAN/RNC TEID and the GGSN TEID of the user plane by notifying the corresponding TEID of the other end point to each end point of the tunnel (i.e., notifying the GGSN of the RNC TEID and notifying the RNC of the GGSN TEID). In the case of handover between RNCs, the SGSN is responsible for updating and providing new RNC TEID information to the GGSN and establishing a single tunnel. In a preferred embodiment of the present invention, the initiation of multiple bearers for multiple services is performed during the primary PDP context initiation while the WTRU is moving the Packet Exchange (PS) add-on. Preferably, the WTRU includes in the additional request a list of services that need to be initiated and an associated Network Service Access Point Identifier (NSAPI). Preferably, then, the SGSN selects an APN (e.g., GGSN or AGW) that performs these services. In the preferred embodiment, MME/upE is used as the SGSN. Preferably, the SGSN (MME/upE) establishes multiple bearers in the radio network M329296 controller (RNC) (or eNodeB). Preferably, the RNC/eNodeB establishes multiple bearers with the WTRU and returns

SGSN confirmed. Preferably, the SGSN (MME/UPE) establishes the required tunnel between the GGSN/AGW and the RNC/eNodeB regardless of whether it is a single channel (LTE or Single Tunnel GPRS) or two tunnels (GPRS). Preferably, then, the SGSN assigns an IP and confirms the assignment of the bearer and its associated NSApi. 7 shows an LTE single GTP tunnel setup (LTE add-on) procedure 700 for initiating multi-bearer services in accordance with the first embodiment of the present disclosure, the procedure for wireless communication including WTRU 705, eNodeB 710, MME/UPE 715, and AGW720 Implemented in the system.
