Description

200939809 IX. INSTRUCTIONS: FIELD OF THE INVENTION The following description relates generally to wireless communications, and more particularly to methods and apparatus for dialog handover procedures in heterogeneous networks.

This application claims the right of U.S. Provisional Patent Application No. 60/950, 583, filed on July 18, 2007, entitled "UMB TO DO - HANDOFF"

And the application filed on March 12, 2008, entitled "METHOD AND APPARATUS FOR HANDOFF BETWEEN ACCESS SYSTEMS", US Patent Application No. 12/047,234, which further claims March 16, 2007 </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; [Prior Art] Wireless network systems have become a common method of communicating with others around the world. Wireless communication devices (e.g., cellular phones, personal digital assistants, and the like) have become smaller and more powerful to meet consumer needs and to improve portability and convenience. Consumers have become dependent on these devices and therefore need reliable services, expanded coverage, additional services (eg, web browsing capabilities), and continue to reduce the size and cost of such devices. In particular, as the evolution of wireless technology continues, mobile services will continue to evolve into increasingly richer, more focused actions and aggregation services. As end users demand more and higher quality 133629.doc 200939809 multimedia content in all environments, the evolution of device technology will continue to increase the increased consumption of data. For example, in recent years, wireless communication technology has evolved from analog-driven systems to digital systems. Typically, in conventional analog systems, the analog signal is switched over a forward link and a reverse link and requires a bandwidth of a significant number I to enable transmission and reception of signals while correlating with appropriate quality. . Since analog signals are consistent in time and space, stateless messages (for example, messages indicating receipt or non-receipt of data) are generated. In contrast, packet switched systems allow analog signals to be converted into data packets and transmitted over a physical channel between a base station, router and the like via an access terminal. In addition, digital data can be transferred in a natural form (e.g., text, mmo: 锷路资#, and similar forms) using a packet switched network. As such, wireless communication systems are widely deployed to provide a variety of communication services, such as telephony, video, data, messaging, broadcast, and the like. Such systems typically employ an access network that connects multiple access terminals to a wide area network (wan) by sharing available network resources. The access network typically has a plurality of access points scattered throughout a geographic coverage area. In addition, the geographic coverage area can be divided into multiple cells with an access point in each cell. Likewise, the cell can be further divided into sectors. However, in this system architecture, it is a challenging task to provision an effective parental effort between access systems that do not share the same communication procedures and policies. SUMMARY OF THE INVENTION A brief summary is presented below to provide a basic understanding of one of the described aspects. This summary is not an extensive overview and is not intended to identify such features. 133629.doc 200939809 Main or critical components are also not intended to be an elaboration of these modalities. Its purpose is to present some concepts of the aspects in a simplified The described aspects achieve the handover of the mobile unit in the heterogeneous network, and further combine between the source access system and a target access system via the use of an intersystem handover control component Dialogue delivery provides an interactive work. As such, the inter-system handover control component can pre-provision tunneling 之一 as part of the dialog negotiation between the AT and the target access system. The packet is accessed via the source access system. Delivering (for example, interrupting during the day of the eve of the eve and reducing the need for a dialogue to be established during the handover.) The patrol can be established from the AT to the target access system (from the perspective of Xiao, &quot;Action-target access system, the transmission is only carried out by this tunnel. This tunneling can be further accompanied by the type of tunneling involved in the end view (for example, whether tunneling occurs at the data link layer) Reaching the other access channel of the target access system. The source access system can further indicate the target access system based on the pilot report, wherein the AT can then communicate with the target access system and establish Negotiation process. In the relevant context, '1' can be used in conjunction with the target access system to leverage the existing mobility model to ensure trust and privacy - secure seamless handover from heterogeneous networks (eg The device crosses the network domain D. The exemplary handover between these heterogeneous access systems can be between Γ Ι 交 - handover: ultra-mobile broadband (umb) and high-rate packets (coffee); wiMax / HRPD; long-term Evolution (L HRPD, where the system architecture can implement the Internet Protocol (IP) line 133629.doc 200939809 mobility to enable the action to actively participate in handover preparation. Another option is that the system A system that is more network controlled than the mobile unit itself can be employed. This interaction enables an action unit to be handed over between different access systems. One of the calls can continue without stopping halfway. According to a related method, An establishment is established between the source access system and the target access system to prepare for the handover session. The establishment may include discovering an interworking security gateway (IWSG) that ensures the security of the transmitted packet. One of the ip addresses. The establishment may further include discovering the radio access network (RAN) or the target location of the target access system. Typically, the RAN-lite system only contains protocol stacks. RAN without radio transceiver function. It also supports the existing ran interface to the core network source and the real RAN. After the conversation has been pre-established with RAN-lite, the existing RAN interface can be used. Hand over) to transmit it to the real RAN. This, for example, makes it possible to perform inter-technology handover to the target system without the need to increase to the existing real RAN (to support L3 tunneling from AT). In the aspect, the RAN_Hte is associated with an agreement (e.g., contained within the action and/or IWSG) that enables the action to discover an IP address and establish a tunnel to pre-establish a conversation with the target radio system. When a handover needs to be transmitted over the air, the conversation negotiated in the RAN-lite can be transmitted via a well-known existing interface. Thus, from the perspective of a wireless access network, access after handover can come from the same radio technology&apos; and therefore there is no need to modify the target radio access system to support heterogeneous system radio technology. The RAN-lite can be used logically as any 133629.doc -9- 200939809 and then the real RAN (for example, a base station controller without actually controlling any physical base station. As long as an action is taken with the ruler 丨丨^ Establishing a tunnel, the action can negotiate a dialogue with the RAN_nte for the action to obtain a dialogue of the target radio technology, and the ruler can store a copy of the conversation of the target radio technology, wherein the action remains May be sourced from the radio technology. Operation, ,,,,,, upon the transfer from the action to the target ❹ radio technology over the air, the action can then access the real RAN of the target access system - for example, Mobile access, and the target access system queries the action for a dialog to negotiate technology. The mobile unit can further provide a unicast access terminal identifier (UATI) or first class that can be used to find the conversation. The identifier 'where the ^^^ from the action can point to the RAN lite, wherein the real RAN can be used to retrieve the conversation from the RAN lite to the real RAN. When extracting a conversation, the The action can then be communicated with the real RAN in the target radio system. It should be understood that the real scale can represent a base station controller that includes the real connection to the base station. The intersystem handover control component can then The AT and the target system implement a wearthrough, wherein the source/system can transmit a message/packet associated with the target system. According to a further aspect, the L3 tunneling provides for transmission between the heterogeneous systems. The function and procedure of the variable length data sequence is notified to maintain service quality and error control functions. This tunneling can be further transparent to the underlying access system regardless of direction (eg, from LTE to HRPD or from HRPD to LTE) (eg, Does not change the source of the ιρ packet.)

It should be understood that this figure is illustrative in nature and that the inter-system handover control component can be part of an access terminal (AT). The dialogue between the AT and the target system can be pre-established, for example, via a • L3 tunneling (through source system). The inter-system handover control component 115 facilitates setting an L3 tunneling inter-system handover control component 115 by means of the mobile unit 104 operating in dual mode (both in the source access system 11 and the target access system 112). The mobile unit 104 is initially enabled to obtain the local domain name associated with the source and/or target access systems 11〇, ιΐ2. Thereafter, the intersystem handover control component facilitates discovery of one of the security gateways of the target access system 112 and one of the radio access network (Ran) ip addresses. This gateway acts as a network point for reaching an entrance to one of the target access systems i12. Thus, the inter-system handover control component 115 enables the 行动 mobile unit to establish L3 tunneling, wherein the signals and packets associated with the target access system 112 can then be transmitted seamlessly via the source access system. As such, the intersystem handover control component 115 can utilize tunneling to exchange handover settings and execute packets as part of the dialog negotiation between the AT 104 and the target access system 112 prior to handover to reduce handover. The interruption of the period and the need to implement a dialogue setting during the handover. The inter-system handover control component 115 further enables the delivery of the communication data packet via the source access system 11 , wherein the source access system 11 is between the AT 104 and the target access 133629.doc • 14· 200939809 system 112 Usually do not participate during the consultation period. 2 and 3 illustrate a particular aspect of L3 tunneling via via an umb system 210 to an HRPD system 215 and vice versa. In FIG. 2, the source access system is represented by UMB system 210, which causes an access terminal or mobile unit 211 to communicate with evolved base stations (eBs) 222, from the eBS to the gateway and local agent to The Internet transmits IP packets. When a handover is requested from UMb 21 (which represents the source access system) to the HRPD access system 215 (which represents the target access system), the HRPD is initially set, during which the mobile unit 2 11 remains in the UMB system. 21 0. The intersystem handover control component can then perform tunneling between the UMB 210 and the HRPD 215, wherein the HRPD signals and associated packets can be transparently transmitted via L3 tunneling, which can be transported via the UMB system 210 via IP. Therefore, the path line 250 indicates the traffic line, wherein the mobile unit 211 in the UMB 210 needs to discover the radio access network 11 of the HRPD 215 into 1^/11 八]^1"€212 and the associated address. To prepare and set up communications (eg, for packet transmission). Upon discovery of the IP address, the HRPD 215 signal can then be transmitted via the RAN lite IP address/packet, where the packets can be stored in the UMB system The gateway (AGw) 2 1 7 is taken and can then be transmitted to the RAN lite 2 12. The packet data service node (pDSN) 219 acts as a connection point between the HRPD RAN 212 and the IP network, where the interworking security gateway (IWSG) 214 may be secured (eg, for IP) via IPsec tunnel 260 to protect packet transmissions between AT 211 and RAN/RAN lite 212. This gateway 214 acts as one of the HRPD target access systems 215 The network point of the portal. In addition, the dialog reference network controller 133629.doc -15-200939809 (SRNC) 21 8 typically includes an authentication function and associated configuration 'between base station 222 and access terminal 211 Negotiate 'and act as base station 222 to capture information (for example, He was a dialogue in order to avoid collisions during the change of dialogue) of a reference.

Similarly, Figure 3 illustrates a further aspect of L3 tunneling via a HRPD 310 to a 111^^ system 315. Upon a handover request from the source system HRPD 310 to the target system UMB 315, UMB 11 VIII &gt; 1 out 6-688 312 can be found and the associated 1; ^ 闸 闸 316 316, 325. For example, 'initially, a 111^18 11 eight]^-out 6 312 can be found associated with the Interworking Security Gateway (IWSG) 325. Subsequently, upon discovery of the ip address, the packet can then be sent to the destination IP address based on tunneling at layer 3 of the communication protocol. "This pre-establishment can then facilitate subsequent packet flow to the UMB target system 315. Figure 4 illustrates an exemplary method for use between heterogeneous systems in accordance with an aspect. While the exemplary mode is illustrated and described herein as a series of various events and/or acts, the present invention is not limited by the order of the illustrated. For example, some acts or events may occur in different orders and/or concurrently with other acts or events, in addition to the order illustrated herein. In addition, it may not be necessary to implement all of the blocks, events or actions in accordance with the methods of the present invention. In addition, it should be understood that the method of describing (4) = reading and other methods can be implemented in association with the methods illustrated and described herein, as well as in the non-illustrated (d) or described devices. Initially at 41. At the same time, the radio condition can be selected to change = 133629.doc •16- 200939809 can trigger a handover preparation request from AT to a target access system. Alternatively, triggering the delivery preparation may be caused by the proximity technology that advertises the target access system as a source access system. Then, and in preparation for the handover session, at 412, a setup can be established between the AT and the target access system. This establishment may include an IP address of one of the interworking security gateways found to ensure the security of the transmitted packet at 41 6 . The establishing may further include discovering at 1 418 the address of the target access system of the size 8^/11 into]^-1丨16. The inter-system handover control component can then perform tunneling between the AT and the target access system at 420, wherein the messaging/packet associated with the target system can be transmitted via the source system. In addition, at 422, the AT negotiates with the target access system an empty mediation session and an IP session. As such, at 424, a radio resource request from the target system is received, followed by assigning radio resources from the target system to the AT at 426. Thus, the IP traffic can be redirected to the AT at 430 (or can also be located after action 434), followed by the handover at 432. Subsequently, at 434, the AT acquires the target system via over-the-air transmission. The following is a specific example of a complete domain name for a DNS lookup that any IP host (eg, an AT) can implement with a DNS server.

FIG. 5 illustrates an exemplary block diagram of one of user device or access terminal 50, source access system 540, and target access system 560. The UE 5 10 includes both the target system protocol 5 11 and the source system protocol 5 1 2 to enable operation in a dual mode with both systems. This configuration enables the discovery of the IP address of the IWSG and the establishment of an IPsec tunnel. In addition, the IP address of a target RAN can be found to enable the target RAN session to be established in advance. Configuration 500 facilitates conversations from source access system 540 to target access system 560 by using handover preparation and handover execution prior to handover by constructing an IPsec tunnel. 133629.doc -18- 200939809. Figure 6 illustrates an exemplary call flow 600 for establishing an _Ip secure channel in accordance with a further aspect. The AT 602 is initially associated with the source access system 〇4&apos; and obtains the domain name of the target access system via a call 610. Thus, the AT 602 can issue a Domain Name System (DNS) 606 query to obtain an IP address of one of the Security Gateways (IWSG) 608 to access the target access system. In addition, the DNS query can further include discovering the IP address of the RAN/RAN-lite of the target access system. The AT 602 can then initiate tunneling to the target access system where the messaging/packet associated with the target system can be transmitted via the source system 604. As explained earlier, an exemplary handover between such heterogeneous access systems may include handover between UMB/HRPD, WiMax/HRPD, LTE/HRPD, where the system architecture may implement IP mobility using client-side mobile IP. In order for the action or access terminal 6〇2 to actively participate in the handover preparation; or alternatively, to adopt a system that is more network controlled than the mobile unit itself. This interaction allows a mobile unit to communicate without having to communicate with the access system, where a call can continue without stopping halfway. FIG. 7 illustrates an exemplary heterogeneous wireless communication system 711, 721 that can service a wireless terminal 726. Systems 711, 721 represent a target access system and a source access system, respectively, comprising a plurality of sectors 7, 2, 704, 708 and 706, 710, 712. The target access system 711 and the source access system 721 can employ different wireless services within such sectors. Although it is shown that the sectors are actually hexagonal and have substantially similar sizes, it should be understood that the size and shape of the sectors may be viewed from a geographic area, physical obstacles 133629.doc -19- 200939809 (eg, buildings) ) varies in number, size and shape, and several other factors. Access points (base stations, access routers, etc.) 714, 716, 720 are associated with sectors 702, 704, 708, with the technique employed, A&quot; as part of it. Similarly, access points 718, 722, 724 are associated with sectors 706, 712, 710, where the technology &quot;B&quot; is employed as part of the technology "B&quot; not the same as technology&quot;A.'. When the wireless terminal 726 is geographically enabled, it can receive a greater strength signal from the target access system 711 than the signal received from the source access system 721. It should be appreciated that the wireless terminal 726 can be associated with the source. Both the access system 721 and the target access system 711 operate in a dual mode - wherein the inter-system handover control component 719 can provide tunneling prior to handover as a dialog negotiation between the AT 726 and the target access system 71 1 Part of the data packet can therefore be transported via source access system 721 (transparent or opaque), the AT is preparing to hand over to the target system, and then the data can be packetized once the handover is completed. Redirecting to the target system.
