Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present invention provides a method for SAIC capability identification, including:

101: and respectively testing the Non-single antenna interference cancellation Non-SAIC type terminal to be tested by using alpha-QPSK (Quadrature Phase Shift Keying) modulation and GMSK (Gaussian Minimum Shift Keying) modulation.

102: and identifying whether the terminal to be tested has the single-antenna interference cancellation SAIC capability or not according to the downlink quality of the terminal to be tested under the alpha-QPSK modulation and the GMSK modulation.

According to the embodiment of the invention, the alpha-QPSK modulation and the GMSK modulation are used for respectively testing the terminal to be tested of the Non-SAIC type, and whether the terminal to be tested has the single-antenna interference elimination SAIC capability or not is identified according to the downlink quality of the terminal to be tested under the alpha-QPSK modulation and the GMSK modulation, so that the silent SAIC terminal with the SAIC capability is identified, and the accuracy of SAIC capability identification can be improved.

Referring to fig. 2, another embodiment of the present invention provides a method for SAIC capability identification.

The network side device may determine, by using the method of this embodiment, whether the terminal has an SAIC capability for a terminal whose reported type is a Non-SAIC type, where the network side device may specifically be a BSC (base station Controller), and this embodiment is not limited, and the specific determination manner may be as follows.

It should be noted that, in the determination process of this embodiment, some detection parameters may be used, and these detection parameters may be configured in advance.

Wherein, detecting the parameter may include: at least one of the number of detections N and the detection time T, the alternation period N and the quality variation threshold. Since the number of times of detection N and the detection time T may be mutually inferred according to the alternating period N, there is only one of the two, and the mutual inference formula is specifically T ═ nxnxnx 2, where 2 denotes two modulation schemes.

The alternate period N represents a modulation mode in which the downlink data of the terminal to be tested is replaced every N time slots, and the modulation modes in this embodiment include alpha-QPSK modulation and GMSK modulation, that is, the modulation mode of the downlink data of the terminal to be tested is switched between alpha-QPSK modulation and GMSK modulation every N time slots. Wherein, alpha-QPSK modulation is the modulation mode of downlink data defined by VAMOS protocol, the downlink quality of the terminal without SAIC capability will be seriously deteriorated under the alpha-QPSK modulation mode, and the terminal with SAIC capability can normally work under the alpha-QPSK modulation. GMSK modulation is a modulation mode of downlink data supported by a Non-SAIC type terminal, which can normally operate under GMSK modulation.

The larger N is, the larger influence on the terminal to be detected is, and the better the detection result is. The larger the alpha is, the smaller the influence on the terminal to be detected is, and the worse the detection result is. Alpha may be an integer between-8 and 8 in one detection process. Further, in order to take account of the detection result and the influence on the terminal to be detected, the value of alpha may be 0, 1 or 2, and the value range of N may be 10 to 30.

The detection times n represent the times of alternation of the two modulation modes in one detection process, namely the times of alternation of alpha-QPSK modulation and GMSK modulation. n is an integer more than or equal to 1, when n is 1, the two modulation modes are only alternated once, and when n is more than 1, the two modulation modes are alternated for a plurality of times.

The detection time T, represents the maximum time for which the detection process lasts. In order to take the detection result and the influence on the terminal to be detected into account, a time slot with T < 300 can be set.

In this embodiment, when the n-time detection is completed or the detection time T is reached, it may be referred to as a one-time detection process, and the SAIC capability identification is performed according to a result of the detection process.

The quality change threshold M represents a detection threshold for judging whether the terminal to be tested has SAIC capability.

Then, in the detection times N or the detection time T, according to the alternate period N, the terminal to be tested is alternately tested by using alpha-QPSK modulation and GMSK modulation, and the method specifically comprises the following steps:

200: and acquiring the number of the continuous time slots of the current modulation mode.

201: and judging whether the number of the continuous time slots of the current modulation mode reaches N.

If the number of the current modulation mode continuous time slots reaches N, the modulation mode may be changed for the terminal to be tested, that is, step 202 is executed, if the number of the current modulation mode continuous time slots has not reached N, the current modulation mode continues to be used, and step 203 is executed.

202: and changing the modulation mode.

Specifically, if the current modulation mode is GMSK, the modulation mode is changed to alpha-QPSK; correspondingly, if the current modulation mode is alpha-QPSK, the modulation mode is changed to GMSK.

After the modulation scheme is changed, step 203 is executed.

203: and judging whether the current detection times reach a preset detection time n or not, or judging whether the current time reaches a detection time T or not.

Specifically, if the current detection time does not reach the preset detection time n, or the current time does not reach the preset detection time T, step 201 is executed; if the current detection time reaches the preset detection time n, or the current time reaches the preset detection time T, step 204 is executed.

In this embodiment, the deviation degree between each random mass correlation value and the mean value thereof can be reflected by the preset variance, and the terminal to be tested with a large deviation degree does not have the SAIC capability.

The embodiment may also perform a plurality of detection processes, for example, change the value of alpha in the alpha-QPSK modulation mode according to the alternative S alpha values, and continue to perform the next detection process according to the changed alpha value. If the second downlink quality related value is larger than the quality change threshold in the S alpha values under any one or more alpha values, determining that the terminal to be tested does not have SAIC capability; or if the fourth downlink quality related value is not between M1 and M2 in the S alpha values under any one or more alpha values, determining that the terminal to be tested does not have SAIC capability; or, if the sixth downlink quality related value is larger than the quality change threshold in the S alpha values under any one or more alpha values, determining that the terminal to be tested does not have SAIC capability.

Further, when the terminal to be tested has SAIC capability, a VAMOS (Voice service over Adaptive Multi-user Orthogonal Sub-channels, Voice service Multi-user Orthogonal Sub-channels) may be enabled for the terminal to be tested. VAMOS multiplexes two users together for transmission on a time-frequency resource for transmitting one user in TCHH (Traffic Channel-half rate) to increase the number of users in the System, which is a new characteristic acquired by GSM (Global System for Mobile Communications).

In addition, in this embodiment, the difference between the downlink qualities of the two modulation modes is compared with the quality change threshold, so that the influence of channel interference factors can be offset to a certain extent, and the accuracy of measurement can be improved.

It should be noted that, in this embodiment, values of M, M1, and M2 may be set according to actual needs, and this embodiment does not limit this.
