detailed description

 In order to make the objects, technical solutions and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. An embodiment of the present invention provides a method for obtaining RIP. As shown in FIG. 1, the method includes the following content.

 5101. Obtain a timestamp of the PHR and a location of the PRB to which the PHR belongs.

 The user terminal sends a PHR on each timestamp, so each PHR has a corresponding timestamp. When the terminal sends a PHR, the PRB is pre-allocated to send the PHR. The location of the PRB to which different PHRs belong may be different.

5102. Determine a RIP according to a timestamp of the PHR and a location of a PRB to which the PHR belongs. In the embodiment of the present invention, when the user terminal sends each PHR, there is a timestamp for sending each PHR, and the PRB in the frequency domain resource is allocated when the timestamp of each PHR is sent. The PHR sent by the user terminal corresponds to a time domain location (such as a timestamp) and a frequency domain location (for example, the location of the PRB to which the PHR belongs). If the PHR sent by the user terminal is different, the timestamp of sending the PHR may be different, and the location of the PRB may be different. The time domain location is determined by a timestamp, and the frequency domain location is determined by the physical resource block PRB, that is, the range of the PRB to determine the frequency domain location. The PHR may have a value on a single PRB, or may have multiple consecutive PRBs. Value.

 In the embodiment of the present invention, the RIP generated by the base station may also include a time domain location (such as a timestamp) and a frequency domain location (such as a location of a PRB to which the RIP belongs), and a time domain location and a frequency domain location of the RIP and a time domain of the PHR. The location and the frequency domain location are related to each other, for example, the RIP corresponding to the PHR. The timestamp of the RIP may be determined by the timestamp of the PHR, and the location of the PRB to which the RIP belongs may be the same as the location of the PRB to which the PHR belongs.

 The executor of the embodiment of the present invention may be a base station or a tracking acquisition entity (TCE). Further, if the executor of the embodiment of the present invention is a base station, the base station may further send the acquired PHR and the RIP corresponding to the PHR to the TCE.

 The RIP of the PHR can be associated with the PHR by using the obtained timestamp of the PHR and the location of the PRB to which the PHR belongs, and the RIP sent by the base station can distinguish the specific terminal by using the association. The PHR sent. In MDT, network coverage quality and system performance can be more accurately detected, thereby reducing the cost of network maintenance. Another aspect of the embodiments of the present invention provides a method for obtaining RIP. As shown in FIG. 2, the method includes the following content.

Embodiments of the present invention focus on further refinement of the steps described in S102 of FIG. The concepts and processes described in the method embodiments shown in FIG. 1 are not described again. Determining the RIP according to a timestamp of the PHR and a location of the PRB of the PHR includes the following content.

 S201: Determine a timestamp of the RIP according to a timestamp of the PHR.

 Optionally, determining the timestamp of the RIP according to the timestamp of the PHR, including: time of the RIP in the time domain of the RIP that is smaller than a timestamp of the PHR and closest to a timestamp of the PHR. Determining the timestamp as the timestamp of the RIP; or determining, in the time domain of the RIP, a timestamp of one or more RIPs that is greater than a timestamp of the last PHR and less than a timestamp of the PHR as the RIP Timestamp.

 S202: Determine, according to the timestamp of the RIP and the location of the PRB to which the PHR belongs, the location of the PRB to which the RIP belongs under the timestamp of the RIP.

 S203: Determine the RIP according to the location of the PRB to which the RIP belongs according to the timestamp of the RIP.

 In the embodiment of the present invention, the time stamp of the corresponding RIP may be determined according to the timestamp of the PHR, and the timestamp of the PHR may not be aligned with the timestamp of the RIP. Therefore, when determining the timestamp of the RIP, there are two alternative implementations: (A) a timestamp less than the timestamp of the PHR and the timestamp of the RIP closest to the timestamp of the PHR may be selected as the RIP. (B) The timestamp of the one or more RIPs of the last PHR sent by the user terminal and less than the timestamp of the PHR may be determined as the timestamp of the RIP. In the manner of determining the timestamp of the RIP in the (B), the timestamp of the RIP is one or more timestamps, and the RIP on each timestamp is the RIP corresponding to the PHR sent by the terminal.

In the embodiment of the present invention, the RIP corresponding to the timestamp of a PHR may be a RIP under multiple timestamps. Under the same timestamp of RIP, since the location of the PRB to which the PHR belongs may be multiple (for example, PRBO, PRB1, and PRB2), the location of the RIP corresponding to different PBRs may also have different values. In this case, in RIP. Same timestamp The value of RIP can be one or more. For example, in the timestamp of the RIP, the location of the PRB to which the PHR belongs is assumed to be PRBO, PRB1, and PRB2, then the RIP corresponds to three values in the location of the associated PRB, that is, RIPO on PRB0 and RIP1, PRB2 on PRB1. On the top is RIP2.

 As an example, the timestamp of the RIP is determined according to method (A). As shown in Figure 3a, RIPlx, RIP2x, and RIP3x are the values of different timestamps of RIP in the time domain (X is 1, 2, 3, ...), PHR1, PHR2, PHR3, etc. are PHR. The value of different timestamps. As shown in Figure 3a, the value of RIP on different timestamps can be one or more. Differently, the timestamp of the PHR is mapped to the time domain of the RIP. After comparison, it can be found that: RIP2x corresponds to the timestamp of the PHR2 in the time domain and the timestamp of the RIP closest to the PHR2, so the timestamp timestamp of the RIP2x is determined to be PHR2. The timestamp of the RIP; similarly, the timestamp of the RIP6x can be found as the timestamp of the RIP that is smaller than the PHR3 in the time domain and closest to the PHR3, so the timestamp of the RIP6 is determined as the timestamp of the RIP corresponding to the PHR3. Further, after determining the timestamp of the RIP corresponding to the PHR, the RIP corresponding to the PHR may be determined according to the location of the PRB to which the PHR belongs, for example, the location of the PRB to which the PHR3 belongs is PRBO. , PRBl, assuming RIP61 corresponds to PRBO, RIP62 corresponds to PRBl, RIP63 corresponds to PBR2, and B'J and PHR3 correspond to RIP as RIP61 and RIP62. Further, it is assumed that the location of 100 PRBs (PRB0, PRB1, RPB99) is allocated for normal communication of the user terminal, and when the user terminal transmits PHR3, and PRB0 and PRB1 are occupied, the PHR3 can be determined according to the method (A). The timestamp of the RIP is the timestamp corresponding to (RIP61, RIP62, RIP63...). On the timestamp, the location of the PRB to which RIP61 and RIP62 belong is PRB0 and PRB1, then the RIP corresponding to PHR3 can be determined as ( RIP2, RIP3).

As an example, the effective timestamp of the RIP is determined according to method (B). As shown in Figure 3b, RIPly, RIP2y, and RIP3y are different timestamps on the RIP time domain. Values (y values are 1, 2, 3, ...), PHRl, PHR2, PHR3... are values taken on different timestamps of PHR. As shown in FIG. 3b, the value of RIP on different timestamps may be one or more. The timestamp of the PHR is mapped to the time domain of the RIP. After comparison, it can be found that: in the time domain of the RIP between PHR1 and PHR2, there are two timestamps corresponding to RIPly and RIP2y, and the two times corresponding to RIPly and RIP2y are taken. The timestamp is the timestamp of the RIP corresponding to the PHR2. Similarly, in the time domain of the RIP corresponding to the PHR2 and the PHR3, there are four timestamps corresponding to RIP3y, RIP4y, RIP5y, and RIP6y, and the four timestamps are taken as the corresponding PHR3. The timestamp of the RIP, where each timestamp may have a different RIP value. After determining the timestamp of the RIP corresponding to the PHR, the RIP can be determined. For example, the timestamp of the RIP corresponding to PHR2 is 2 (the timestamp corresponding to RIP ly and RIP2y), and the location of the PRB to which PHR2 belongs is PRB3. Assuming that the PRB to which RIP11 and RIP21 belong are PRB3, the RIP corresponding to PHR2 is (RIP11, RIP21). Similarly, assuming that the PRB location to which PHR3 belongs is PRB0 and PRB1, the RIP corresponding to PHR3 is a matrix [RIP31 RIP32; RIP41 RIP42; RIP51 RIP52; RIP61 RIP62].

 It should be noted that the foregoing method may be performed by the base station eNB or may be uploaded to other network side devices.

 As an optional embodiment of the present invention, the embodiment of the present invention further includes: setting an index for the RIP corresponding to each PHR, where the index is used to indicate a timestamp corresponding to the RIP of the PHR, and a location of the PRB to which the RIP belongs.

The RIP of the PHR can be associated with the PHR by using the obtained timestamp of the PHR and the location of the PRB to which the PHR belongs, and the RIP sent by the base station can distinguish the specific terminal by using the association. The PHR sent. In MDT, network coverage quality and system performance can be more accurately detected, thereby reducing the cost of network maintenance.
