For example, the user equipment may include a smart phone, a tablet computer, a personal digital assistant (PDA), a mobile internet device (MID), and other clients. Customer Premise Equipment (CPE), which is not limited by the present invention.

For convenience of description, the following describes an LTE network as an example. According to the 3GPP protocol, the eNB initiates a UE capability query to the UE, and the UE reports the corresponding UE capability information.

The UE's capability level is ranked according to the capabilities it implements. As shown in Table 1, the UE's capability level includes at least the following:

Table 1 UE capability level

In practical applications, there are UEs whose actual capabilities exceed the capability level.

The embodiment of the invention discloses a method, a system and a device for acquiring a user equipment capability, which can enable an eNB to accurately identify the capability of the UE.

Referring to FIG. 1B, FIG. 1B is a method for acquiring user equipment capability according to an embodiment of the present invention. The method may include the following steps.

101. The UE reports the first capability information of the UE to the eNB by using an RRC message.

In the embodiment of the present invention, the UE may report the first capability information of the UE to the eNB by using a capability information (UECapabilityInstance) message. Optionally, the UE may also report the first capability information of the UE to the eNB by using a UECapabilitylnformation message after receiving the UE Capability Enquiry message sent by the eNB.

In the embodiment of the present invention, the first capability information includes at least one of the following or a combination thereof: a supported protocol version (Access Stratum Release), a UE capability level (UE Category), a PDCP parameter (PDCP Parameters), and a physical layer parameter ( Physical Layer Parameters, RF Parameters, Meas-Parameters, Supported Feature Group Indicators, and other inter-RAT parameters supported.

102. The UE indicates the second capability information to the eNB by using a MAC Control Element (MCE), where the second capability information is different from the first capability information, so that the eNB is configured according to the first capability information and the second Capability information, configure the user plane and/or control plane of the UE.

In this embodiment of the present invention, the UE may indicate the second capability information of the UE to the eNB by using an index value reserved by the LCID field of the MCE packet header.

In the LTE system, the MAC layer defines some special MAC PDUs (Media Protocol Control Units), which are used to quickly transmit control signals between the UE and the eNB. Let these packets be called MCE. The data type carried by the data packet is identified by a 5-bit Logical Channel Identify (LCID) field in the packet header. The LCID field definition of the MAC packet header is as shown in Table 2: Table 2 LCID field of the MAC PDU packet header

As can be seen from Table 2, 01011-11000 is the reserved value defined by the protocol.

In the embodiment of the present invention, the data packet using any one of the foregoing reserved values may be used as an MCE, and the second capability information indication is performed by using the MCE.

In the embodiment of the present invention, the capability that the second capability information is different from the first capability information of the UE is that the second capability information is capability information other than the first capability information. For example, according to the 3GPP, the UE with the capability level of 3 can only support the 16QAM in the uplink modulation mode. If the UE's own software and hardware support the uplink modulation mode can be 64QAM, the MCE can indicate the second capability information to the eNB. The second capability information supports the 64QAM for the uplink modulation mode. For example, for the downlink MIMO in the UE capability level, the MIMO mode adaptation needs to be performed according to the actual environment. However, in some scenarios, the MCE may indicate to the eNB. The second capability information is that the downlink MIMO mode is a closed loop mode, which can be processed by the system.

The specific value of the reserved value of the LCID field is not limited in the embodiment of the present invention. The correspondence between the MCE and the second capability information may be predefined for the specific capabilities of the UE. If that The UE has a plurality of special capabilities, and the indication of different second capability information can be performed by using a plurality of predefined MCEs.

Optionally, the UE may indicate the second capability information to the eNB through the MCE if it is determined that the preset condition is met. The foregoing preset condition may include any one of the following or a combination thereof:

1) The UE receives the second capability information request sent by the eNB;

2) The UE has no uplink data service.

After receiving the MCE sent by the UE, the eNB can learn the second capability information indicated by the MCE according to the index value of the LCID field of the MCE.

For example, the MCE with the LCID field index value of 10010 is defined as the first MCE, and the first MCE is used to indicate that the second capability information of the UE supports the 64QAM in the uplink modulation mode. After receiving the first MCE, the eNB can learn the The UE has the second capability information that supports the 64QAM in the uplink modulation mode. The MCE that defines the LCID field index value is 11000 is the second MCE, and the second MCE is used to indicate that the second capability information of the UE is the closed MIMO mode. After receiving the second MCE, the eNB can learn that the UE has the second capability information that the downlink MIMO mode is the closed loop mode.

In the embodiment of the present invention, the eNB may configure a user plane and/or a control plane of the UE according to the first capability information and the second capability information of the UE.

For example, for a UE with a capability level of 3, the first capability information is as shown in Table 1. If the UE has the second capability information of the uplink modulation mode supporting the 64QAM, the eNB learns the second of the UE by using the predefined MCE. After the eNB configures the user plane and/or the control plane of the UE, the eNB can comprehensively consider the first capability information and the second capability information of the UE, and the UE can use the 64QAM modulation mode that is not supported by the UE to perform uplink data transmission with the eNB. Improve network performance.

In the method described in FIG. 1B, the first capability information may be reported to the eNB by using an RRC message, and the second capability information may be indicated to the eNB by using the MCE, so that the eNB can accurately identify the capability of the UE, and enable the eNB to perform the first according to the UE. The capability information and the second capability information configure a user plane and/or a control plane of the UE, and improve network performance on the premise that the eNB accurately identifies the UE capability. Referring to FIG. 2, FIG. 2 is another method for acquiring user equipment capability according to an embodiment of the present invention. The method can include the following steps.

201. The eNB acquires first capability information of the UE by using an RRC message.

In the embodiment of the present invention, the eNB may acquire the first capability information reported by the UE by using a capability information (UECapabilityInstance) message. Optionally, the eNB may send a capability query (UECapabilityEnquiry) message to the UE, and then the eNB may acquire the first capability information sent by the UE by using the UECapabilitylnformation message.

In the embodiment of the present invention, step 201 corresponds to step 101 in the previous embodiment.

202. The eNB acquires second capability information of the UE.

The International Mobile Equipment Identity (IMEI) is the identifier of the UE, and its total length is 15 bits, including 6 bits of TAC information, which is used to identify the UE model.

In the embodiment of the present invention, different types of UEs may have different capability information, and a UE of a special model may have second capability information. The corresponding relationship between the TAC information and the second capability information may be defined in advance. After the eNB obtains the TAC information of the UE, the eNB may obtain the second capability information of the UE according to the foregoing correspondence.
