The network element (310) comprises packet inspection logic (313) arranged to inspect received PS data packets that are being routed through the network element (310) and extract a first portion of PS data packets. The network element (310) further comprises routing logic (312), operably coupled to the packet inspection logic (313), for routing the first portion of PS data packets to a destination node directly over the Internet (330) and routing a remaining portion of PS data packets of the received PS data packets over the cellular communication network based on the packet inspection. In this manner, PS data may be selectively routed direct to a destination node, say directly over the Internet, or via the cellular communication network.

Description

200935826 IX. INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The field of the invention relates to a data communication system, a communication network component, and a method for routing data. In particular, the field of the invention relates to a method of routing a network element phantom data to a wireless (mobile) communication unit within a building of a/self-femtocell communication network. [Prior Art] Data communication in both wireless and wireline communication systems is generally used

Circuit switched (cs) or packet switched (PS) techniques are implemented. In ps technology, the data is packetized, where the packet switched routing is established between the source node and a destination node. In wireless communication systems, the established cellular radio communication system is the Global System for Mobile Communications (GSM), often referred to as a second generation (10) system. One of the enhancements to this cellular technology can be found in the General Packet Radio System (GPRS), which supports the basic cellular platform (eg on gs(4)). One of these communication systems is further enhanced by the standard of mobile phone standards and technologies. Generation 3 (3G). The example of such 3G standards and technologies is the Universal Mobile Telecommunications System (UMTS), which was developed by the 3rd Generation Partnership Project (WWW.3gPP.〇rg). It is expected that the 3G system will provide A harmonious standard, in the heart of the 'honeycomb radio communication network and system will provide enhanced interface level' and compatibility with other types of communication systems and networks (including fixed communication systems such as the Internet). The coffee s and UMTS/3GPP network systems are also adapted to Ps material to facilitate support such as web browsing, file sharing, and email L network services. 136597.doc 200935826 In a computer network or data communication system Known techniques for routing data packets sometimes utilize a network address translation (also known as phishing, native address translation, or IP impersonation). NAT is a type of transceiver that transmits and receives packets through a router. The technology 'The router is involved in overwriting the known source and/or destination Internet Protocol (IP) address when passing through the router, and the usual Transmission Control Protocol (TCP) of the usual additional IP data packets. User Datagram Protocol (UDP) port number. Most systems that use NAT do this 'in order to implement a private network

Multiple hosts access the Internet using a single public IP address. NAT has become one of the routers for home and small office internet connections

Standard features where the price of additional IP addresses often exceeds the benefits. NAT also adds security because it pretends to structure the internal network: for the peripherals, all traffic appears to be sent from the gateway machine. When traffic is passed from the regional network to the Internet, the source address in each packet is immediately translated from the private address to the public address. The router tracks basic information about each active connection (especially, destination address and 埠). When a reply is returned to the router, it uses the NAT to store the connection trace data stored during the outgoing data stream to determine where to forward the reply on the internal network; when the packet is returned, in the case of overloaded NAT Use the Transmission Control Protocol (TCP) or User Datagram Protocol (UDp) client-side number to demultiplex the packets, or when multiple public addresses are available, use the 15> address and the 埠 number. For the system on the Internet, the router itself appears to be the source/destination of the traffic. Typically, a wireless communication unit (or as often referred to as user equipment 136597.doc 200935826 (UE)) communicates with a core network (CN) of a wireless communication system via a radio network (RNS). A wireless communication network typically includes a plurality of radio network subsystems, each unheated network subsystem including one or more cells to which the UE can attach and thereby connect to the network. 'The femtocell or picocell access point (AP) is a nested communication system, the most recent development in the domain. A femtocell or picocell is supported by a low-power base station (or called a feed communication unit). These cells can be transported to the more widely used macro-homed network and support the Limit (eg, " UEi communication in an in-building environment. By way of example, such femtocell or picocell AK typical applications include residential and commercial (eg, office) locations, "hotspots", etc., where An AP can be connected to a core network via, for example, the Internet using a broadband connection or the like. In this manner, the femtocell or picocell can be provided in a particular building within a simple, scalable deployment. This site is for example a network congestion based on the cluster level.

φ Referring now to Figure 1, a known architecture for configuring a 3GPP network for routing PS data is illustrated. The architecture 1 includes a user equipment 110 that desires to receive or access a PS, for example. Information, in order to access Ps data 'PS traffic will currently be received on the following data path. A server 17 transmits the desired pS data over the communication path 175, 165 across the internet gateway to a gateway GPRS support node (ggsn) 160. The 〇 (} state then transmits the PS data to a 3rd generation access controller (3G AC) 140 via a Serving GPRS Support Node (SGSN) 150 and communication paths 155, 145. If the UE 1 receives the PS data The data will then be transmitted from the radio network controller I36597.doc 200935826 (RNC) 140 via the internet 130 and a NodeB 120 along the communication path 135 ' 125. The NodeB 120 will then For example, the PS data is transmitted 115 to the UE 110 wirelessly.

Therefore, in a known 3G (macro cell) network, all such PS data traffic must be passed through the SGSN 150 and the GGSN 160 in order to reach its final destination 'from the UE 110 to the Internet. One of the destination nodes (e.g., server 170), or from one of the source nodes outside the wireless network to the UE 100. Typically, most of the final destination of this PS material will be addressed to the public Internet. Referring now to Figure 2, there is shown a graphical representation of one of the known femtocell plane stacks in a femtocell architecture. What is important is that compared to a 3GPP macro-cell architecture, the packet data convergence protocol Radio Link Control (RLC)/Media Access Control (MAC) functions are all implemented in the AP in the AP-based cell architecture. Executed in the Radio Network Controller (RNC). Referring back to Figure 1, it is also known that a cellular network operator may desire to provide a personal or group operator service 19G to its mobile users. In this context, the Firewall Anti-Purple Zone (Effective Ferry) 18〇 allows the operator to provide dedicated services to users who cannot be accessed by people on the public network. Possible dedicated services include support for email communications or delivery of SMS (SMS) messages. Additional firewall defense zones (not shown) may be used to provide a ferry between the UE 110 and some of the public services. An example of a filter can include a previous generation control or a post-processing of the paper, reading the display on the optimized mobile device. 136597.doc 200935826 It is currently assumed that there is no requirement to reduce the traffic load on the operator's firewall defense zone. Here, the network operator keeps the PS traffic low by charging a high fee for the data. In a femtocell network, imagine that such network operators may expect to provide very low cost for PS data. As a result, it is expected that the amount of PS data on the network will be greatly increased. An important part of this PS service is to book a computer that can be accessed via the Internet.

However, the size of the existing SGSN 150 and GGSN 16 will need to increase significantly in order to dispose of commercial (4) material for femtocell technology. s (10) position (10) N1_ force to support the increase of PS data services) may be extremely expensive. 'Thus, there is a need for a method and apparatus for routing data (e.g., packet switched data) in a data communication network including both fixed (e.g., internet communication) and wireless communication, which is directed to solving past and current technologies and / or at least some of the shortcomings of the organization. SUMMARY OF THE INVENTION Accordingly, the present invention is directed to preferably reducing, alleviating or eliminating one or more of the above disadvantages, either individually or in any combination.

These and other aspects, features, and advantages of the invention will be apparent from the description of the appended claims. [Embodiment] According to a specific embodiment of the present invention, a 3rd generation (3 g) access point (Ap) is configured to selectively handle certain PS data packets, such as user plane PS traffic' Leave other user plane traffic to be carried out via the SGSN/GGSN. In a specific embodiment of the present invention, for example, all control plane PS traffic is routed through a wireless communication SGSN/GGSN in a month-by-side manner, and the user plane ps traffic is retrieved, for example, via The internet is routed directly to the destination node. Advantageously, the current changes to the packet switching architecture include the addition of routing logic and NAT logic to the 3G AP communication unit (network element). Thus, in this manner, a mechanism is provided that allows a femtocell network to directly route certain packet switched (ps) data directly to a final destination node, such as via the Internet; thereby omitting the existing SGSNs And GGSN wireless communication network components. While the inventive concept utilizes NAT logic, it is contemplated that any suitable address translation logic or technique can be used. Referring now to FIG. 3, an example of a wireless network architecture 300 adapted in accordance with an embodiment of the present invention is illustrated. Those skilled in the art will recognize and appreciate that the details of this example are merely illustrative of specific embodiments, and that the teachings presented herein can be applied to various alternative network settings. For example, since 136597.doc -13. 200935826 the teachings described below are not dependent on a cellular communication network consistent with any particular standard, it is contemplated that the teachings and inventions described herein can be applied to any type of cellular communication network. However, this concrete implementation shows a 3GPP femtocell network. As such, it encompasses alternative embodiments of the wireless (e.g., cellular) communication network with different standards and is considered to fall within the scope of the various teachings.

The wireless network architecture 3 of Figure 3 illustrates both the logic and a communication layer layout to illustrate the individual functions handled by the respective logic elements: the information type. The wireless network architecture 300 includes a 3G Access Point (3G AP) 31G' that has been adapted in accordance with a particular embodiment of the present invention. As will be appreciated by those skilled in the art, the '-3G Access Point' (3G Ap) is a communication element that facilitates access to a communication network via, for example, a femto cell. One application of the inventive concept described herein is where a number of people purchase a 3G AP' and install it in their home. The 3G Ap (31〇) is connected to any _3g access control controller (3G AC) 340 (eg, 'femtocell controller') over a broadband connection across the owner of the Internet 330, such as As described below. The 3G AC 340 is operatively coupled to (3(}8]^16〇 and an SGSN 150° in a known manner. Obviously, in accordance with a particular embodiment of the present invention, the 3G Ap 31 is adapted to Into router logic 312, which may include (or operatively coupled to) packet inspection logic 313, and NAT logic 316 in direct communication path 322 with one of the Internets 330. Thus, reference is made to FIG. The known mechanism, wherein all PS traffic is delivered to the femto A to the 3G AP and thereafter to the SGSN 150 and the GGSN 160, 136597.doc 200935826 packet inspection logic 313, political class Router logic 312 and AT logic 3 16 are incorporated into the 3G AP 310, and are configured to route PS data packets according to their data content. In Figure 3, the user plane traffic passes through the right side of the graph. The packet is transmitted through the PDCP layer, and the PDCP header has been stripped off, and the remaining data is the user's data packet. The IP data packet received from the UE has a source address, which is set. Assigned to one of the PDCP responsibilities during startup The UEi ιρ address. The π data packet also includes a destination address based on the desired destination server. The user data packet is then routed based on the source address, the destination address, and the protocol. Each (or several) received data packets 'is made by the packet inspection logic 313 as follows: whether the data packet is directly routed to the Internet 33 or forwarded to the wireless communication network The SGSN 150 of the road is based on the verified data content. In particular, according to an embodiment of the present invention, the packet inspection logic 3 13 of the 3G AP 3 10 is configured to check the packet exchange data and from the PS The user plane message retrieves a first portion of the PS data, such as 'user plane ps traffic destined for the SGSN 150 and the GGSN 160. According to a specific embodiment of the present invention, the ps data packet is captured and rerouted. A first part is conceived to include at least the following: fetching and rerouting one or more PS data packets from a series of multiple PS data packets, and extracting and rerouting a single PS One or more parts of the data packet. In the following, for the purposes of simplification only 136597.doc -15- 200935826, a reference to a portion of the ps data will refer to a series of multiple ps data packets and reroute one or more The PS data packet is encapsulated by the former. The routing logic 312 is then configured to route the user plane traffic to the NAT logic 3 16 . Thus, in a particular embodiment of the invention, based on the source and purpose The IP address, along with the protocol and usage agreement, the routing logic 313 determines whether to route 332 the first portion of the PS data packet to the SGSN 150 and GGSN 160, or whether to route the first portion of the 资料3 data packet directly 322. To the Internet 330, and to a destination node 370. Modifying the source Internet Protocol (IP) address to the 3G AP 3 10 for the data packet directly routed from the UE source to the Internet do 'the NAT logic 3 16 is configured' The address is compared to the IP source address of the UE. While updating the source IP address, NAT Logic 3 16 also modifies the source 珲 number as would be appreciated by those skilled in the art. Such changes to the ps data packet ensure that any replies to the directly routed PS data are correctly routed directly back to the 3G AP 310' rather than through existing wireless communication network elements (ie, SGSN 15 0 and GGSN 160) )come back. Clearly, the NAT logic 316 is operatively coupled to (or includes) a mapping table 315 'which is used by the NAT logic 3 16 to cause the original source address and source to be associated with the modified source address and the modified source.埠 Connected. Upon receiving the PS data packet destined for the UE from the Internet 330, the NAT logic 316 in the 3G AP 310 queries the destination address and the 埠 number in the mapping table 315 to locate the original source address and The original port, 136597.doc -16- 200935826, performs a reverse NAT function and transmits the destination IP address back to the IP address of the UE. The 3G AP 3 10 also includes a memory component, including a routing table 317, which specifies which traffic should be transmitted to the Internet, and which traffic should be transmitted to the SGSN 150 and GGSN 160. Imagine that routing table 317 can utilize any number of rules, such as rules according to an ordered order, as will be appreciated by those skilled in the art. In an example, the rules for imagining the ordered order may be as follows: (i) all PS data packets destined for a server having a fixed range of ip addresses are transmitted to the SGSN 15 0 and GGSN 160; (ii) All other PS data packets are directed to the destination node 370 via the Internet 33. A simple example of a configuration of one of the routing tables 317 is illustrated in Table 1: Table 1: Source Address Destination Address Routing to 10.1.* * 192.168.*.* SGSN/GGSN 10.2.*.* 氺氺氺* * · SGSN/GGSN Pre-routed Internet This routing table 3 Π states that there is any packet routing starting at "10.1" one of the source addresses and starting at one of the destination addresses of "1 92.168" GGSN. Any user plane PS data packet with a source address starting at "10. 2" is routed to the GGSN. All other user plane Ps data packets are routed directly to the Internet. The routing table 3 17 utilized by the 3G AP can be configured to route user plane PS data according to any of a number of factors. For example, the routing table 136597.doc 17 200935826 3 17 can be routed according to the following user plane Ps data: (0 source 1P address. Here, it is imagined that the UE can simultaneously connect to multiple networks through multiple GGSNs. In this way, the UE will be assigned a different IP address by each (10). Therefore, based on Routing of source IP addresses facilitates utilization for each GGSN Routing options. (11) Destination IP address: Some network operator services that the UE may wish to use are only accessible via the GGSN; they are not accessible from the Internet. For example, a BlackberryTMt sub-mail server The device may only be accessible via e mggsn. If all of the network operator services are grouped on a network, then routing on the destination IP address is useful. (Out) Agreements for use (eg, based on The destination 埠): can take this road

The primary option is used, for example, when all UE emails arrive at the GGSN 160's 帛ft' and all Hypertext Transfer Protocols are sent via the Internet 330 to the destination node 37. In the case of a knife, the destination can be used to determine the agreement. However, in some embodiments of the present invention, it is envisaged that for some agreements, the user plane PS data packet may require more detailed examination. In order to determine the protocol of use, in the embodiment of the present invention, it is assumed that when the UE initiates a packet exchange session, a k message (control plane ps data) is transmitted to the SGSN 150 and the GGSN 160 as usual. In an alternative embodiment of the present invention, it is envisaged that the 3G AP is also configured to detect (four) the plane PSf and (or to compare) the user plane PS data. Therefore, the specific implementation is performed here, and the non-user plane is imagined. I36597.doc • 18- 200935826 PS data routing is directed to the destination node wo, or both non-user plane PS data and user plane PS data are routed to the destination node 370 = Please note that checking and disposing of such messaging messages and the user plane requirements resolve several other topics, for example, in this embodiment, to set an encryption key (which is stored in the core network) And can be accessed by the SGSN 150. It needs to be additionally accessible by the 3G Ap 31〇 to preserve the data. Referring now to Figure 4, an illustration of a PS user plane stack directly unloaded to the Internet packet is illustrated. Graphical representation, in accordance with an embodiment of the present invention. As can be seen from Figure 4, it is simpler than the example 'contraction stacking system' shown in Figure 2. When processing packets from the UE, After removing the PDCP header, the 3G AP can directly transmit the packet to its destination instead of the 3G AC, SGSN, and GGSN. This reduces the amount of traffic handled by the SGSN and the GGSN. Reducing its cost. This also gives the user a more responsive service because the round-trip time between the 1] and the destination is reduced. Referring now to Figure 5, the description is based on an uplink direction (ie, from Source node A flowchart 500 of an exemplary method of routing ps data via a network to a destination node, in accordance with an embodiment of the present invention. The flowchart begins in step 505 'where in _ 3G The Ap receives PS data from a UE. The 3G AP includes routing logic or a signal processor that performs a routing operation, which is configured to make routing decisions in step 51. In step 515, the 3G Ap routing logic or The signal processor selects the first routing rule to be utilized. The routing logic or signal processing then 136597.doc • 19- 200935826 in step 52 determines if the received PSf packet is matched with the selected rule. If the connected (four) data packet does not match the selection rule at step 52G, the routing logic or signal processor selects the lower rule at (4) (2) and the method returns to the packet verification step 52.

If the pure PSf packet is matched with the material out rule in step 520, the routing logic or money processing 11 determines, in step 530, based on the internal order of the PS data packet, whether to route the ps data packet to the known manner. GGSN, or whether to route the psf packet to the internet. If the routing logic or signal processor does not decide to route the packet to the GGSN, the PSf is routed to the 3g ac for forwarding to the SGSN and GGSN, as shown in step 545. However, if the routing logic or signal processor determines in step 53 that the data packet route is directed to the internet, the ps data is routed to the NAT logic in the 3G AP in step 535, and in step 54 From there to the internet. Referring now to Figure 6, a flowchart of an exemplary method of routing PS data in a downlink direction (i.e., from a source node to a ue as a destination node) is illustrated in accordance with an embodiment of the present invention. Here, in the 3G AP, in step 605, the ps data is received from the internet. In step 610, the PS data is routed to the NAT logic to determine the original source address and the associated port number. The ps data is then routed to the corresponding UE as shown in step 615. It will be appreciated that, for the sake of brevity, the above description has been described with reference to various functional elements, logic elements and signal processors to illustrate specific embodiments of the invention. I36597.doc •20· 200935826 It is obvious to those skilled in the art that any functional unit, logic element or signal processing (eg, relative to the 3G network element) can be used, and any suitable distribution can be used. Without damaging the concept of a month. For example, it is contemplated that the illustrated functionality performed by a separate signal processor or logic component can be performed by the same signal processor or logic component. Therefore, reference to a particular functional unit should be considered merely as a reference to the means of providing the described functionality, and not to a strict logical or physical structure or organization. It is contemplated that aspects of the invention may be practiced in any suitable form, including hardware, software, bodily or any combination of these. The present invention can be implemented, at least in part, as computer software running on one or more data processors and/or digital signal processors. Thus, the components and components of one embodiment of the present invention can be implemented in any suitable manner in terms of functionality, functionality, and logic. In fact, functionality can be implemented in a single unit, in a plurality of units, or as part of other functional units. It is envisioned that the foregoing inventive concept is directed to providing one or more of the following advantages: The preparation of routing logic in a network element (e.g., a 3G AP) achieves a significant increase in psf traffic sent over the Internet without increasing the SGSN and The complexity and cost of the GGSN. The concept of the invention is only required to support the functionality provided within a 3G AP' and is backward compatible with current 3GPP PS data routing. The concept of the invention provides a significantly more efficient transfer of PS data.
