Description

Information reporting method and device
Technical Field
The present invention relates to the field of communications, and in particular, to a method and apparatus for reporting information.
Background
Inter-machine (Machine to Machine, abbreviated as M2M) communication is an important issue in current research of fifth-generation mobile communication technology (5G), and is also an important application field of future wireless communication. In the M2M problem, a research sub-problem of narrowband internet of things (NarowBand-Internet of Things, abbreviated as NB-IoT) is proposed for the characteristics of low-cost low-throughput terminals: i.e., provide low throughput wireless communication services for NB-IoT low cost terminals (UEs) in the 200khz band.
NB-IoT introduces different uplink narrowband access capabilities (Single-Tone) for UE low cost features. A Single-Tone capable terminal can only use Single-Tone type resources.
NB-IoT introduces an optimized data transmission scheme (control plane transmission based optimization scheme, user plane transmission based optimization scheme) for the characteristics of small data volume transmission. Wherein: the basic idea of the control plane transmission-based optimization scheme is as follows: packaging the data packet into NAS PDU and attaching the NAS PDU to the control plane signaling for transmission; the basic idea of the optimization scheme based on the user plane transmission is as follows: the terminal and the eNodeB use a data radio bearer (Data Radio Bearer, abbreviated AS DRB) to transmit data, after the data transmission is finished, the two parties store bearer information context, an Access layer (AS) security context and the like, and when the data is sent again subsequently, the two parties quickly recover the use of the DRB bearer through a suspension-recovery flow. For NB-IoT UEs: the control plane transmission based optimization scheme is a function that must be supported, while the user plane transmission based optimization scheme is an optional function. For UEs that do not support an optimized scheme based on user plane transmission, the network side cannot use the scheme for data transmission.
In addition, for a UE supporting both the control plane transmission-based optimization scheme and the user plane transmission-based optimization scheme, the UE may instruct which scheme to prefer for data transmission according to its own mobility, data characteristics with transmission. If the two transmission optimization schemes are supported by the traditional LTE terminal, three requirements of terminal capability and preferable indication reporting capability exist.
The current CT1 standard is related to the data transmission mode as follows: the transmission optimization scheme supporting capability and the optimization indication of the UE are reported to the MME through the initial UE attachment, and the MME stores the transmission optimization scheme supporting capability and the optimization indication for subsequent use; information such as these capabilities of the UE are not visible to the eNodeB. There are several problems with this: 1. if the UE capability or the optimized transmission scheme preference indication is changed after the initial attachment of the UE is completed, the strategy is not updated; the eNodeB cannot acquire the capability of the UE if the UE is hoped to switch between two transmission optimization schemes; and 3, when the eNodeB selects the MME, if the UE capability and the MME capability need to be matched, the UE capability cannot be acquired at the moment.
Further, which optimized data transmission scheme the UE adopts is determined by the MME. When the MME selects an optimized data transmission scheme for the UE, it needs to know whether the eNodeB supports the optimized data transmission scheme capability. The eNodeB may also connect multiple MMEs, which also needs to know if the MME supports optimized data transmission scheme capabilities when selecting the MME for the UE in order to match the UE capabilities and MME capabilities. RAN3 currently agrees: the optimized data transmission scheme support capability of the eNodeB and MME may interact in the S1 port setup and response message. But if the optimized data transmission scheme support capability of the eNodeB or MME changes. No policy informs the correspondent node.
There is currently no effective solution to the above-described problems in the related art.
