Description

Method and device for reporting information

Technical field

The present invention relates to the field of communications, and in particular to a method and apparatus for reporting information.

Background technique

Machine to Machine (M2M) communication is an important subject of the fifth generation of mobile communication technology (5G), and an important application field for wireless communication in the future. In the M2M project, for the characteristics of low-cost low-throughput type terminals, a sub-topic of the NarowBand-Internet of Things (NB-IoT) is proposed: that is, NB-IoT in the 200khz band. A low-cost wireless communication service is provided by a low-cost terminal (User Equipment, UE for short).

NB-IoT introduces different uplink narrowband access capabilities (Single-Tone, Multi-Tone) for the low-cost characteristics of the UE. A Single-Tone capable terminal can only use resources of the Single-Tone type.

NB-IoT introduces an optimized data transmission scheme based on the characteristics of small data transmission (optimization scheme based on control plane transmission, optimization scheme based on user plane transmission). The basic idea of the optimization scheme based on the control plane transmission is: packetizing the data packet into the NAS PDU attached to the control plane signaling; the basic idea of the optimization scheme based on the user plane transmission is: the terminal and the eNodeB use the data radio bearer ( Data Radio Bearer (DRB) transmits data. After the data transmission is completed, both parties save the bearer information context, and the access layer (Access Stratum, AS for short) security context. When the data is sent again, the two parties pass the suspend-resume process. To quickly restore the use of DRB bearers. For NB-IoT UEs: The optimization scheme based on control plane transmission is a function that must be supported, and the optimization scheme based on user plane transmission is an optional function. For UEs that do not support the optimization scheme based on user plane transmission, the network side cannot use this scheme for data transmission.

In addition, for a UE that supports both the control plane transmission-based optimization scheme and the user plane transmission-based optimization scheme, the UE may indicate which scheme is preferentially selected for data transmission according to its own mobility and data characteristics with transmission. If the traditional LTE terminal also supports the two transmission optimization schemes, there are three terminal capabilities and a requirement for indicating the reporting capability.

The current CT1 standard is related to the data transmission mode. The UE's transmission optimization scheme support capability and the preference indication are reported to the MME through the initial UE attachment, and the MME saves the subsequent use; the UE's capabilities and other information are invisible to the eNodeB. There are several problems in this way: 1. If the UE capability or the optimized transmission scheme preferably indicates that a change has occurred after the initial attachment of the UE is completed, there is no update policy; 2. The eNodeB cannot obtain the UE if it wants to switch between the two transmission optimization schemes. The capability of the UE; 3. If the eNodeB needs to match the UE capability and the MME capability when selecting the MME, the UE capability cannot be acquired at this time.

In addition, 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. When the eNodeB selects the MME for the UE, it also needs to know whether the MME supports the optimized data transmission scheme capability. It matches the UE capability and the MME capability. At present, RAN3 agrees that the optimized data transmission scheme support capability of the eNodeB and the MME can interact in the S1 port setup and response messages. However, if the eNodeB or MME's optimized data transmission scheme support capabilities change. Then there is no policy to notify the other node.

In view of the above problems in the related art, there is currently no effective solution.

Industrial applicability

In the confidence reporting process of the embodiment of the present invention, the user equipment UE sends a setup or resume to establish a radio resource control to the base station. The RRC connection request is made, and when the UE establishes an RRC connection with the base station, the UE reports the capability information of the UE and/or the preferred indication information for indicating the data transmission mode to the base station; for example, in the embodiment, the UE establishes an indication with the base station. When the RRC is connected, the UE reports the capability information of the UE and/or the preferred indication information for indicating the data transmission mode to the base station, that is, the base station acquires the capability information of the UE and/or the preferred indication information for indicating the data transmission mode, and the solution is solved. In the related art, since the transmission optimization scheme support capability and the preference indication of the UE are saved in the MME, the eNodeB is invisible, which causes the eNodeB to fail to acquire the UE capability.
