Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein.
The application scenario of the embodiment of the invention is data packet loss statistics when the core network is transmitted to the base station side. A Serving Gateway (SGW) of the core network transmits data to the base station eNodeB through an S1-U port, and the eNodeB transmits data to the user terminal through an air interface. Compared with the prior art that packet loss statistics under the SGW is carried out by means of SGW optical splitting signaling acquisition, packet loss statistics of the S1-U port or air-interface packet loss cannot be determined, the data packet loss statistics of the S1-U port can be realized by the embodiment of the invention aiming at the S1-U port. Compared with the prior art that the center can only carry out the statistics of the air interface packet loss on the eNodeB side, the embodiment of the invention realizes the statistics of the data packet loss of the S1-U interface on the eNodeB side. The following describes specific embodiments.
Fig. 1 shows a flowchart of a statistical method for data packet loss number of S1-U port according to an embodiment of the present invention, which is performed on the eNodeB side. The eNodeB is a radio base station in the LTE network, and is configured to receive data of a core network and send the data of the core network to a user terminal. As shown in fig. 1, the method comprises the steps of:
step 110: and acquiring the data packet of the target user transmitted by the S1-U port.
In this step, the S1-U port is a transmission interface for transmitting data packets between the core network and the base station eNodeB of the target cell. The target cell is any cell which needs to count the packet loss number of the S1-U port data packet. The target user is any user in the target cell, and a corresponding identifier is pre-established for any user in the cell at the eNodeB side, and the identifier may be a Tunnel Endpoint Identifier (TEID) at the eNodeB side. The data packet carries a user identifier, and the user identifier corresponds to the identifier of the eNodeB side one by one, so that the user to which the data packet belongs can be determined according to the user identifier carried in the data packet. For each user in the target cell, the packet loss number is counted according to the method of the embodiment of the invention, and the counting of the packet loss number of each user in the target cell can be carried out simultaneously. The embodiment of the present invention takes a packet loss number statistical method of a target user as an example for explanation. The obtained data packet carries the number of the data packet itself. For example, the packet is a packet transmitted through a GPRS tunnel protocol-user plane (GTP-U), and the packet header includes a packet number.
Step 120: and judging whether the data packet number is the same as the expected data packet number, if so, executing the step 130, otherwise, executing the step 140.
In this step, the expected number is the number of the data packet expected to be received. The expected number is updated in real time. The initial expected number is set according to the number of the data packet carried by the first data packet received for the target user for the first time. The packet numbers in the current network are incremented by 1, that is, the sequence of the packet numbers is 1, 2, 3,4, etc. Therefore, after receiving the first data packet, the data number of the expected received data packet is the data number carried by the first data packet plus 1, i.e. the initial expected number is the sum of the data number carried by the first data packet and 1. The expected sequence is the sequence of the numbers of the data packets expected to be received, the expected sequence is an arithmetic sequence with a tolerance of 1, and the first bit of the expected sequence is the sum of the number of the data carried by the first data packet and 1. For example, if the number of the data packet carried by the first data packet is received is 2, the initial expected number is 3, and the expected sequence is 3,4,5, 6.
Step 130: the expected number is updated to the first number.
In this step, if the packet number is the same as the expected number, the expected number is updated to the first number. Wherein the first number is adjacent to the expected number in the expected sequence and the first number is greater than the expected number. For example, the expected number is 3 and the expected sequence is 3,4,5,6,7,8,9. If the number of the second received packet is 3, the expected number is updated to the first number 4.
Step 140: it is determined whether the packet number is greater than the expected number, and if so, step 150 is performed, otherwise, no action is performed.
Step 150: a preset timer is started and the packet number is removed from the expected sequence.
In this step, if the number of the data packet is greater than the expected number, a preset timer is started, and a timing duration of the preset timer may be set in advance by a person skilled in the art when implementing the embodiment of the present invention, which is not limited thereto. The purpose of starting the preset timer is to determine whether a packet with a packet number equal to the expected number can be received before the timer expires. Since a packet greater than the expected number has been received, the packet number is removed from the expected sequence in order to avoid updating the packet number to the expected number. For example, the expected number is 3 and the expected sequence is 3,4,5,6,7,8,9. If the number of the second received data packet is 4, the expected number 4 is deleted from the expected sequence, resulting in a deleted expected sequence 3,5,6,7,8,9.
After the timer is started and before the timer expires, the base station side may not receive any data packet, which indicates that the base station side does not receive the data packet carrying the expected number before the timer expires, then step 180 is performed. If the base station side receives the data packet before the timer is over time, the received data packet has three situations: first, if a new packet with a packet number greater than the expected number is received, the step 160 is executed; secondly, if a data packet carrying an expected number is received, the step 170 is executed; thirdly, if a packet with a packet number less than the expected number is received, no action is performed. The execution processes of the steps 160 to 180 are not in sequence.
It should be understood that, in the above three cases, at least two cases may be corresponding before the timer expires, and then the corresponding steps are executed. For example, after the timer is started and before the timer is over time, a new data packet carrying a data packet number greater than the expected number and a data packet carrying the expected number are received in sequence, then step 160 is executed first, and then step 170 is executed. It is also possible to receive at least one data packet before the timeout after the timer is started, but the received data packet does not carry the data packet with the expected number, and then execute the corresponding step of step 180.
Step 160: and if a new data packet carrying a data packet number larger than the expected number is received before the timer is overtime, deleting the data packet number carried by the new data packet from the expected sequence.
In this step, if a new packet carrying a packet number greater than the expected number is received before the timer expires, the packet number carried by the new packet is deleted from the expected sequence, so as to avoid updating the packet number to the expected number in the subsequent expected number updating process. For example, if a new data packet is received before the timer expires, the data packet carried by the new data packet is numbered 5, then 5 is deleted from the expected sequence, and the deleted expected sequence is 3,4,6,7,8,9.
Step 170: if a packet carrying the expected number is received before the timer expires, the expected number is updated to the second number.
In this step, the second number is adjacent to the expected number in the expected sequence, and the second number is greater than the expected number. If the data packet carrying the expected number is received, the core network is indicated to send the data packet out of order in the process of sending the data packet to the base station, but the packet is not lost. For example, the expected number is 4 and the expected sequence is 3,4,5,6,7,8,9. if a packet carrying the expected number 4 is received before the timer expires, the expected number is updated to 5.
Step 180: and if the timer does not receive the data packet carrying the expected number before the timeout, accumulating 1 for the packet loss number corresponding to the target user, and updating the expected number to be the second number.
In this step, if the timer does not receive the data packet carrying the expected number before timeout, it is determined that a packet loss occurs, and the number of packet losses corresponding to the target user is accumulated by 1. It should be understood that the initial packet loss number is 0, and the packet loss number is accumulated by 1 every time packet loss occurs until a preset time period is reached, so as to obtain an accumulated value of the packet loss number. The preset time period is a packet loss number counting time period, and the accumulated value of the packet loss numbers is the packet loss number of the target user in the preset time period.
Step 190: and accumulating the packet loss numbers of all users in the target cell within a preset time period to obtain the packet loss number of the S1-U port of the target cell within the preset time period.
In this step, the packet loss number of each user in the target cell is counted according to the steps of steps 110 to 180, and the packet loss number of each user is accumulated to obtain the packet loss number of the S1-U port of the target cell in the preset time period.
The embodiment of the invention counts the packet loss number by setting the expected number and the expected sequence, starts the timer when the number of the data packet carried by the received data packet is greater than the expected number, and accumulates the packet loss number if the data packet carrying the expected number is not received before the timer is overtime. By the method provided by the embodiment of the invention, on the premise that the core network sends the data packets out of order, the timer is started to wait for the reception of the data packets carrying the expected numbers, so that the statistics on the packet loss number of the S1-U port is realized, and the quality of the S1-U port is further evaluated according to the packet loss number obtained by the statistics.
In some embodiments, if a data packet carrying the expected number is received before the timer expires, the expected number is updated, and the timer is stopped, so as to avoid occupying computing resources by the timer.
