Description

Method and device for establishing data radio bearer

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for establishing a data radio bearer.

Background

With the continuous evolution of wireless communication technology and standards, mobile packet services have been developed greatly, and the data throughput of a single terminal is continuously improved. Taking a Long Term Evolution (LTE) system as an example, the data transmission with the downlink maximum rate of 100Mbps can be supported within a 20M bandwidth, and in a subsequent LTE (LTE advanced) system, the data transmission rate will be further improved, even reaching 1 Gbps.

Due to the expansion of terminal data traffic volume, the existing network resources are gradually unconscious, and especially under the condition that a new generation communication technology (such as 3G, LTE) cannot be widely distributed, the user rate and traffic demand cannot be met, and the user experience is worsened. How to prevent and change the situation is a problem which must be considered by operators, and on one hand, the popularization and network deployment of new technologies need to be accelerated; on the other hand, it is desirable to enhance the existing networks and technologies to achieve the goal of rapidly improving network performance. As is well known, in addition to Wireless Network technologies provided by The 3rd generation partnership Project (3 GPP), Wireless Local Area Networks (WLANs), especially based on The Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, which are currently in widespread use, have been widely used in home, business, and even The internet for hotspot access coverage. Among them, the technical specification proposed by the WiFi Alliance (Wi-Fi Alliance) is the most widely used, so in practice, the WiFi network is often numbered with the WLAN network based on the IEEE 802.11 standard, and without causing confusion, the WiFi module is also used hereinafter to describe the wireless transceiving and processing module supporting the WLAN in the network node.

Under the premise, some operators and companies have proposed to merge the WLAN and the existing 3GPP network to implement joint transmission, so as to achieve the purposes of load offloading and improving network performance. The 3GPP SA2 provides a mode for selecting a target Access Network for a terminal according to an operator policy through an Access Network Discovery and Selection Function (ANDSF) scheme.

3GPP R10 defines ANDSF standard, ANDSF is used as access anchor point to realize intelligent network selection, and effective shunting of network access is realized through interactive cooperation of network and terminal, thereby conforming to the operation direction of future multi-network cooperation. The ANDSF makes strategies based on information such as network load, terminal capability, user subscription conditions and the like, helps a terminal user to select an optimal access network system, and achieves collaborative operation of multiple access modes. The ANDSF may be deployed alone or in combination with other network elements. Currently, the industry is in a mainstream view of a scheme that ANDSF can be deployed on PCC devices.

The ANDSF is a WLAN interworking scheme based on a core network, and does not consider an influence on an access network, and in addition, because the ANDSF is a relatively static scheme, it cannot well adapt to a situation that a network load and a channel quality dynamically change, so that a WLAN interworking discussion is also carried out in a 3GPP access network group. In R12WLAN/3GPP wireless interworking, a mechanism to perform rules and triggers for WLAN offloading is introduced.

However, the core network mechanism and the supplementary information mechanism from the radio network cannot provide the network side to use the load and channel condition in real time to use the radio resources in combination. In addition, data from the same bearer cannot be served over both the 3GPP and WLAN links. The need for WLAN integration with 3GPP networks is therefore re-addressed at the RAN65 for the first time.

Compared with the WLAN offloading scheme depending on policy and trigger, which has been researched at present, the RAN-level aggregated WLAN is integrated with a 3GPP network, which is abbreviated as WLAN and 3GPP network tightly coupled, and similar to carrier aggregation and dual connectivity, provides better control and utilization of resources on dual connectivity for the overall system. Tight integration and aggregation at the radio layer allows more real-time joint scheduling of the radio resources of the WLAN and the 3GPP network, thus improving user QoS and overall system capacity. By better managing the radio resources among the users, the collective throughput of all users can be increased and the overall system capacity provided. Each link scheduling decision can be made to be per packet level based on real-time channel conditions and system usage. The user plane is anchored in a reliable LTE network and performance can be improved by fallback to the LTE network.

There are currently four WLAN offloading schemes for tightly coupling WLANs to 3GPP networks: simplified architecture PDCP layer shunting, PDCP layer shunting of dual-connection architecture, RLC layer shunting and MAC layer shunting.

Fig. 1 is a schematic diagram of a WLAN offloading architecture for tightly coupling a WLAN and a 3GPP network in the prior art. In the architecture shown in fig. 1, only a WLAN offloading architecture in which a WLAN is tightly coupled with a 3GPP network is defined, and a Data Radio Bearers (DRBs) is newly introduced, where the DRB is specifically characterized in that a PDCP layer is located at a 3GPP network side, and an MAC layer and a physical layer for transmitting a PDCP protocol Data unit are located in the WLAN network, which is referred to as a WLAN-based 2C DRB, where 2C represents a C option of a second scheme. Since no discussion is made on the method of newly introduced 2CDRB setup configuration of the tightly coupled network system under the architecture, the setup of 2C DRB is an essential technique for achieving tight coupling.
