Embodiment 1

[0064] Embodiment 1 of the present invention proposes a terminal capability reporting system, such as figure 1 As shown, including network-side equipment and terminal-side equipment, where:

[0065] The terminal-side device, including the terminal, is configured to determine the terminal type to which it belongs, and send a first signaling message including a specified field used to identify the terminal type to the network-side device.

[0066] The network-side device is configured to receive the first signaling message sent by the terminal-side device that includes a specified field for identifying the terminal type, and determine the terminal according to the protocol version supported by the communication network and the specified field in the first signaling message The belonging terminal type determines the terminal capability of the terminal according to the determined terminal type in the set correspondence between the terminal type and the terminal capability. And ac...

Embodiment 2

[0115] Accordingly, based on figure 1 As shown in the system architecture, Embodiment 2 of the present invention also proposes a terminal capability reporting method, such as figure 2 As shown, the specific processing flow is as follows:

[0116] Step 21, the terminal determines its own terminal type.

[0117] In the LTE communication system, several types of terminals are defined. For example, in the LTE standard of 3GPP Release 8-11 protocol versions, a total of 8 types of terminals are defined, and each type of terminal corresponds to different terminal capabilities. Therefore, terminals with different capabilities can work normally in the LTE communication system.

[0118] With the continuous development of communication technology, the downlink 256QAM is introduced to improve the throughput of the downlink communication system. Correspondingly, it is necessary to support 256QAM terminals to access the communication system. Therefore, in the technical solution proposed...

Abstract

The present invention discloses a terminal capability reporting method and device. The method comprises the following steps of: receiving a first signaling message which is transmitted by a terminal and contains a specified field used for identifying terminal types; determining the terminal type to which the terminal belongs according to a protocol version supported by a communication network and the specified field in the first signaling message; and determining the terminal capability of the terminal in set corresponding relationships of terminal types and terminal capabilities according to the determined terminal type. With the terminal capability reporting method and device adopted, the terminal can support a capability for receiving 256QAM signals, and terminals having capabilities for receiving 256QAM signals can work normally when entering communication networks of lower versions.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for reporting terminal capabilities. Background technique [0002] At present, in the long-term evolution (English: Long Term Evolution, abbreviation: LTE) communication system, three modulation and demodulation methods are supported, namely, quadrature phase shift keying (English: Quadrature Phase Shift Keying, abbreviation: QPSK), 16 quadrature Amplitude modulation (English: Quadrature Amplitude Modulation abbreviation: QAM) and 64QAM. Since 64QAM has high requirements on the radio frequency capability of the terminal transmitter, the uplink 64QAM is optional for the terminal, and only some types of terminals support it. [0003] In order to support terminals with different capabilities to work normally in the LTE communication system, several terminal types (English: UE Category) are defined in the LTE standard, and the maximum trans...
