Description

Method and device for realizing user plane address binding

Technical field

This document relates to the technical field of implementing user plane address binding, and in particular to a method and device for realizing user plane address binding.

Background technique

With the continuous evolution of wireless communication technologies and standards, mobile packet services have been greatly developed, and the data throughput capability of single terminals is constantly improving. Taking the Long Term Evolution (LTE) system as an example, the downlink maximum rate of 100 megabits per second (Mbps) data transmission can be supported in a 20 megabit (M) bandwidth, and the subsequent enhanced LTE (LTE Advanced) system The data transmission rate will be further increased, even reaching 1 (Gbps).

The inflated growth of terminal data traffic has made existing network resources incapable, especially in the case that next-generation communication technologies (such as 3G and LTE) cannot be widely deployed, followed by user rates and traffic. The demand cannot be met and the user experience is getting worse. How to prevent and change this situation is an issue that operators must consider. On the one hand, it is necessary to speed up the promotion of new technologies and network deployment; on the other hand, it is hoped that the related networks and technologies can be enhanced to achieve rapid improvement of network performance. . As is well known, in addition to the wireless network technology provided by the 3rd Generation Partnership Project (3GPP), wireless local area networks (WLANs), especially based on electrical and electronic engineers, have been widely used. Wireless LANs of the IEEE (Institute of Electrical and Electronics Engineers) 802.11 standard have been widely used in hotspot access coverage in homes, businesses, and even the Internet. Among them, the technical specifications proposed by the Wi-Fi Alliance are the most widely used. Therefore, the WiFi network is often equated with the WLAN network based on the IEEE 802.11 standard. In the case of no confusion, the WiFi module is also used later. To describe the WLAN-enabled wireless transceiver and processing module in the network node.

Under this premise, some operators and companies have proposed to integrate WLAN with related 3GPP networks to achieve joint transmission to achieve load shunting and improve network performance. 3GPP SA2 passes the access network discovery and selection function unit (ANDSF, Access Network Discovery The Support Functions scheme provides a mode for selecting a target access network for a terminal based on an operator policy.

The 3GPP R10 defines the ANDSF standard. The ANDSF acts as an access anchor to implement intelligent network selection. Through the interaction between the network and the terminal, the network access is effectively offloaded, which is in line with the future multi-network coordinated operation direction. The ANDSF formulates policies based on information such as network load, terminal capabilities, and user subscriptions to help end users select the best access network standard and implement coordinated operation of multiple access modes. ANDSF can be deployed separately or in combination with other network elements. At present, the mainstream view of the industry believes that the ANDSF can be deployed on a Programmable Computer Controller (PCC) device.

ANDSF is a WLAN interworking scheme based on the core network. It does not consider the impact on the access network. In addition, because the ANDSF is a relatively static scheme, it is not good to dynamically change the network load and channel quality. Adaptation, so WLAN interworking discussions have also been carried out in the 3GPP access network group. In R12 WLAN/3GPP wireless interoperation, a mechanism for performing WLAN offloading rules and triggering is introduced.

However, the core network mechanism and the auxiliary information mechanism from the wireless network cannot provide the network side with real-time use of load and channel conditions to consolidate the use of radio resources. In addition, data from the same bearer cannot be served on both 3GPP and WLAN links. Therefore, the need for WLAN integration with 3GPP networks was reintroduced at the RAN65 subliminal.

Compared with the WLAN offloading scheme that relies on policy and triggering, the WLAN based on the access network (RAN) is integrated with the 3GPP network. The WLAN and the 3GPP network are closely coupled, similar to carrier aggregation and dual. Connections provide better control and utilization of resources for dual connectivity for the overall system. Tight integration and aggregation at the wireless layer allows more real-time joint scheduling of WLAN and radio resources of the 3GPP network, thus improving user quality of service (QoS) and overall system capacity. By better managing the wireless resources between users, it is possible to increase the collective throughput of all users and provide the entire system capacity. Based on real-time channel conditions and system usage, each link scheduling decision can be made to the level of each packet. The user plane is anchored to a reliable LTE network and can be improved by rolling back to the LTE network.

Between the WLAN and the 3GPP network, the RAN can be applied to the co-location scenario (the Evolved Node B (eNB) and the Access Point (AP) to complete the RAN through the internal interface. Layer integration operation and physical integration, essentially similar to 3GPP carrier aggregation, the scenario is usually a small cell) and non-co-location scenarios (the eNB and the AP complete the RAN layer integration operation through the external interface, which is essentially similar For double connection) and. FIG. 1(a) is a schematic diagram of a co-local cooperation method applied to a WLAN and a 3GPP integrated base station site, and FIG. 1(b) is a schematic diagram of a non-cooperatively applied WLAN and a 3GPP network for ideal loop connection, and FIG. 2 is a co-operation. A schematic diagram of a scenario applied to a small cell layout.

There are currently four WLAN offloading schemes that are closely coupled to the WLAN and the 3GPP network: Layered Packet Data Convergence Protocol (PDCP) layer splitting, PDCP layer splitting of the dual connectivity architecture, and Radio Link Control (RLC) Layer shunting, media access control (MAC, Media Access Control) layer shunt.

The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) protocol belong to the transport layer protocol. TCP provides reliable data transmission under the Internet Protocol (IP) environment. It provides services such as data stream transmission, reliability, effective flow control, full-duplex operation and multiplexing. Send via connection-oriented, end-to-end and reliable packets. UDP is mainly used in transmissions that do not require packet sequence arrival. The inspection and ordering of packet transmission order is completed by the application layer, providing a transaction-oriented simple unreliable information transmission service. Both the UDP protocol and the TCP protocol retain their respective data transmission channels using applications with different port numbers. UDP and TCP are on top of IP. The application accesses the UDP layer and then uses the IP layer to transmit datagrams. The header of the IP layer indicates the source and destination host addresses, while the headers of the UDP layer and the TCP layer indicate the source and destination ports on the host.

The above solution only defines the WLAN offload architecture that is tightly coupled between the WLAN and the 3GPP network, but does not discuss the binding process of the user plane address (such as IP address and/or UDP port) of the tightly coupled network system. Considering that the data of the terminal user plane address is offloaded to the WLAN side, it is necessary to know the user plane address of the terminal in the WLAN network. Otherwise, the 3GPP network side cannot encapsulate the user data stream using the WLAN network to the WLAN side, and the terminal side The user plane address of the WLAN network needs to be known. Otherwise, the terminal side cannot encapsulate the user data stream using the WLAN network to the WLAN side, that is, the WLAN and 3GPP network tight coupling functions cannot be implemented.

Preferred embodiment of the invention

The following is an overview of the topics detailed in this document. This Summary is not intended to limit the scope of the claims.

The invention is further described below in conjunction with the accompanying drawings and is not intended to limit the scope of the invention. It should be noted that the embodiments in the present application and the various manners in the embodiments may be combined with each other without conflict.

Referring to FIG. 3, the present invention provides a method for implementing user plane address binding, including:

Step 300: The radio resource control device of the first network sends, to the terminal, a user plane address used by the radio resource control device of the first network corresponding to one or more services in the second network.

In this step, the user plane address used by the radio resource control device of the first network in the second network refers to: when the radio resource control device of the first network performs the service through the second network, the radio of the first network corresponding to the service The user plane address of the resource control device.

In this step, when the radio resource control device of the first network sends the user plane address used by the radio resource control device of the first network corresponding to the one or more services to the terminal, the radio resource control device may also send the indication terminal to the terminal. The information that the network performs the measurement and/or the target network identification ID of the second network.

In this step, the first network may be a 3GPP network, and the second network may be a WLAN network.

In this step, the radio resource control device of the first network may send, by using a downlink message, the user plane address used by the radio resource control device of the first network in the second network, or the wireless network of the first network corresponding to one or more services. The user plane address used by the resource control device in the second network, and information indicating that the terminal measures the second network and/or the target network identification ID of the second network. The downlink message may be the first network downlink radio resource control message, and the downlink radio resource control message may be sent in the first network downlink bottom layer encapsulation or the second network downlink bottom layer encapsulation.

In this step, the user plane address used by the radio resource control device of the first network in the second network includes one or more of the following: an IP address, a UDP port number, a TCP port number, a MAC address, and a general packet radio service technology ( GPRS, General Packet Radio Service) tunneling protocol Endpoint identifier (TEID, Tunnel Endpoint Identifier).

In this step, when the first network is an LTE system and the dual link technology is adopted, the user plane address used by the radio resource control device of the first network in the second network is generated by the secondary base station (SeNB, Secondary eNB) and passed. The X2 interface is delivered to the primary base station (MeNB, Master eNB), and then sent by the MeNB to the terminal through a downlink message. If a single link technology is employed, the user plane address used by the radio resource control device of the first network in the second network may be generated by the second network or generated by the first network. The first network or the second network may use the related method to generate the user plane address of the radio resource control device of the first network in the second network, and is not used to limit the protection scope of the present invention, and details are not described herein again.

In this step, when the terminal has multiple services concurrently, the downlink message may simultaneously carry the user plane of the second network using the radio resource control device of the first network corresponding to some or all of the concurrent services. The address may also be a partial or full service specifying a user plane address used by the unified radio resource control device of the first network in the second network.

In this step, when the radio resource control device of the first network carries the user plane address used by the radio resource control device of the first network in the second network, the radio resource control device of the first network of the plurality of services is The user plane address used by the second network may be partially the same. For example, the radio resource control device of the first network of multiple services has the same IP address in the user plane address used by the second network, but has a different UDP port number or TCP port number.

Step 301: The radio resource control device of the first network receives the user plane address used by the terminal corresponding to each service of the terminal in the second network.

In this step, the radio resource control device of the first network may also save the user plane address used by the terminal corresponding to each service in the second network. In this way, when the RRC device of the first network and the terminal transmit the corresponding service through the second network, the RRC device of the first network can use the user plane address used by the saved terminal in the second network as the target user plane. address. For example, the user plane address used by the saved terminal in the second network is added to the user plane data packet as part of the packet header.

In this step, when the radio resource control device of the first network receives the user plane address used by the terminal corresponding to each service of the second network, the radio resource control device of the first network may also receive the measurement report of the terminal to the second network.

In this step, the user plane address used by the terminal in the second network includes one or more of the following: an IP address, a UDP port number, a TCP port number, a MAC address, and a GPRS TEID.

The IP address and the MAC address can be obtained from the second network, and the TCP port number and the UDP port number can be generated by the terminal. The IP address and the MAC address may be obtained by the terminal interacting with the target network ID of the second network.

Specifically, the user plane address used by the terminal in the second network can be obtained by using the related technology. For example, the IP address and the MAC address can be obtained by using the Dynamic Host Configuration Protocol (DHCP), and is not used to limit the protection scope of the present invention. No longer.

Binding of the user plane address used by the terminal in the second network to the user plane address used by the radio resource control device of the first network corresponding to each service and the user plane address used by the terminal in the second network, Therefore, the radio resource control device of the first network and the terminal can implement the first network by using the bounded user plane address of the first network and the user plane address used by the terminal in the second network. Tight coupling function with the second network.

Referring to FIG. 4, the present invention provides a method for implementing user plane address binding, including:

Step 400: The terminal receives a user plane address used by the radio resource control device of the first network corresponding to the one or more services of the radio resource control device of the first network in the second network.

In this step, the terminal may also save the user plane address used by the radio resource control device of the first network corresponding to one or more services in the second network. In this way, when the RRC device of the first network and the terminal transmit the corresponding service through the second network, the terminal may use the saved user plane address of the RRC device of the first network as the target user plane. address. For example, the saved user plane address of the first network's radio resource control device in the second network is added to the user plane data packet as part of the packet header.

In this step, when receiving, by the terminal, the radio resource control device of the first network corresponding to one or more services of the radio resource control device of the first network receives the user plane address used by the second network, the terminal also receives the first network. Instructing the terminal of the RRC device to measure the second network Information and/or the target network identification ID of the second network.

In this step, the user plane address used by the radio resource control device of the first network in the second network includes one or more of the following: an IP address, a UDP port number, a TCP port number, a MAC address, and a GPRS TEID.

Step 401: The terminal sends, to the radio resource control device of the first network, a user plane address used by the terminal corresponding to each service in the second network.

The user plane address used by the second network.

In this step, the terminal may also send the radio resource to the first network when the terminal corresponding to the service corresponding to the service that can be transmitted by using the second network is used by the terminal to the radio resource control device of the first network. The control device sends a measurement report to the second network.

In this step, when the terminal determines that the service corresponding to each service cannot be transmitted by using the second network, the terminal returns a failure message to the radio resource control device of the first network. Then, the radio resource control device and the terminal of the subsequent first network do not offload the service flow to the second network when performing service transmission.

In this step, the terminal may use the uplink message to the user plane address used by the service corresponding to the service corresponding to the terminal that can be transmitted by using the second network, or the service corresponding to each service or the second network. The user plane address used by the terminal in the second network and the measurement report to the second network are sent to the radio resource control device of the first network. The uplink message may be a first network uplink radio resource control message (such as an RRC reconfiguration response message), and the uplink high layer message may be sent in the first network or the second network uplink bottom layer.

In this step, the terminal may determine whether the service can be transmitted by using the second network according to one or more of the following factors: user setting, constraint configuration from other protocols (such as configuration constraints obtained from ANDSF), and operator on the terminal. Pre-configured.

With the method of the present invention, the terminal receives the user plane address used by the radio resource control device of the first network corresponding to the one or more services of the radio resource control device of the first network, and uses the user plane address of the second network. The RRC device sends the user plane address used by the terminal corresponding to each service that can be transmitted by using the second network in the second network, and implements the user plane used by the radio resource control device of the first network corresponding to each service in the second network. Binding of the address and the user plane address used by the terminal in the second network, so that the radio resource control device of the first network and the terminal can control the user plane used by the second network by the bound radio resource control device The address and the user plane address used by the terminal in the second network implement a tight coupling function of the first network and the second network.
