Description

Method and device for initiating access request by terminal Technical field

This document relates to the technical field of initiating an access request, and specifically relates to a method and apparatus for a terminal to initiate an access request.

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 Mbps data transmission can be supported in the 20 M bandwidth. In the subsequent enhanced LTE (LTE Advanced) system, the data transmission rate will be further improved, and even Up to 1Gbps.

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 existing networks and technologies can be enhanced to achieve rapid improvement of network performance. purpose. 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, are now widely used. Wireless LANs of the Institute of Electrical and Electronics Engineers (IEEE) 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 (Wireless-Fidelity) are the most widely used.

Some operators and companies have proposed to combine WLAN with existing 3GPP networks to achieve joint transmission to achieve load shunting and improve network performance. The 3GPP SA2 (Security Assurance) adopts the Access Network Discovery and Selection Functions (ANDSF) scheme, and provides a mode for selecting a target access network for a terminal according to 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 ANDSF can be deployed on PCC (Policy Control and Charging) devices.

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 solution, it can not adapt to the dynamic changes of network load and channel quality. Therefore, 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 radio access 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 has been reintroduced.

Compared with the WLAN offloading scheme that has been studied and relies on the policy and triggering, the RAN (Radio Access Network) hierarchical aggregation WLAN is integrated with the 3GPP network, and the WLAN and the 3GPP network are tightly coupled, which provides better overall system. The control and utilization of resources on the ground connection. Tight integration and aggregation at the radio layer allows more real-time joint scheduling of WLANs and radio resources of the 3GPP network, thus improving user QoS (Quality of Service) 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.

The close coupling between the WLAN and the 3GPP network can be applied to the co-location scenario (the RAN layer integration operation is performed between the eNB (evolved base station) and the AP (Access Point) through the internal interface) and the non-co-location cooperation scenario (eNB and The RAN layer integration operation is completed between the APs through the external interface.

Before performing the tightly coupled access configuration, the base station needs to know the WLAN status of the terminal. When the base station is connected to the AP, the WLAN status part information of the terminal can be obtained from the WLAN side. Base station The control plane interface that is not shared with the AP. The base station cannot know which AP the UE is connected to at this time. This will cause the base station to have insufficient WLAN information (such as the WLAN address, MAC (Media Access Control) address or IP address) routes tightly coupled packets to the terminal. The base station also cannot be aware of which AP is most effective for load sharing. It is convenient for the base station to learn the necessary information of the WLAN status of the terminal, and the industry has proposed a process for defining information request and response.

The above problem solution, for some terminals that have service requirements with the WLAN, cannot perform tight coupling operation or switching between access networks controlled by the 3GPP network in time, resulting in data retention and delay. For example, in the scenario of FIG. 5, the loosely coupled network of the terminal in the AP1 range is offloaded to the WLAN network in the AP1 range, and the service is performed in the WLAN network, and then the terminal is reselected by the cell to enter the 3GPP network of the tightly coupled system. The cell, because the 3GPP cannot know that the terminal has a service, has been waiting for the UE to initiate a radio access request, so that the tight connection operation or the switching between the access networks controlled by the 3GPP network cannot be performed.
