Description

Method and device for determining wireless resources occupied by service

Technical Field

Background

With the development of mobile internet services, the popularity of intelligent terminals is increasing, users and usage rates of data services based on smart phones are increasing, and the types of application services are increasing. For operators, understanding service usage differences on a loaded network and occupation conditions of the services on network resources has important significance in mastering network resource conditions, optimizing network resource configuration and improving user data service experience.

The radio resources of LTE include control resources and transmission resources. The control resources mainly comprise random access resources, uplink and downlink channel control resources and the like, and the transmission resources mainly comprise the number of PRBs of a shared channel. DPI is a deep packet inspection technology, IP packet data of a user can be acquired by analyzing LTE core network S1-U interface data, and the service of the user can be identified according to an IP address, a service port and a feature code. The CDR is a user call wireless record of LTE, records information of each wireless connection of a user, including connection time, a connection cell, resource occupation and the like, and can be used for evaluating the consumption of each service of the user on wireless resources. The two technologies are separately deployed and applied in the existing network.

Based on the current system architecture of LTE, most of the evaluation schemes for network resources analyze the resources based on the respective layers of EPC or EUTRAN, and the contents acquired by the two layers are not combined for analysis. The isolated method has certain defects, the wireless side cannot know which services occupy more wireless resources, and the data side cannot analyze what wireless behavior characteristics consume more network resources. The current method for determining the occupation of the wireless resources has the following problems: the wireless resource of the network management is counted as a cell level, and the service cannot be subdivided; although the DPI can differentiate services, it can only count traffic flow and duration, and cannot directly correspond to the radio resource.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

First, an embodiment of the method for determining radio resources occupied by a service according to the present invention is described with reference to fig. 1.

Fig. 1 is a flowchart illustrating an embodiment of a method for determining radio resources occupied by a service according to the present invention. As shown in fig. 1, the method for determining a radio resource occupied by a service in this embodiment includes:

step S102, deep packet inspection DPI service data and a user wireless call record CDR are obtained.

Data related to resources are collected at the wireless side, and the data can include user level granularity data such as user wireless call records CDR, measurement reports MR, signaling tracking TRACE and the like. The user wireless call record data needs to contain specific information of RRC connection, such as connection setup time, connection duration, uplink and downlink connection persistent flow, number of PRBs occupied by uplink and downlink connections, and connection occupied time slot.

And collecting data related to the service in a mode of combining the DPI of the core side by using a probe or the PGW with MME signaling, wherein the data comprises S1-U service plane data, S1-MME signaling plane data, S11 signaling plane data and the like, and the S1-U service plane data comprises DPI service data. The service identification data includes information of each TCP/IP connection of the user, such as a source IP address, a destination IP address, a protocol number, a source port, a destination port of the connection, and a service type obtained by identifying the service according to the feature library.

Step S104, the CDR of the same user is associated with the DPI service data.

CDR and DPI service data can be transmitted to relevant correlation devices through the northbound interface to be correlated. In the association process, the CDRs of the same subscriber can be associated with DPI service data by the international mobile subscriber identity IMSI of the subscriber.

And step S106, determining the occupation situation of various services to wireless resources by analyzing the associated CDR and DPI service data.

The occupation conditions of various services on wireless control resources, wireless access resources and wireless service resources can be determined by analyzing the associated CDR and DPI service data. The method for analyzing the associated CDR and DPI service data is described in detail in the following classification.

In the embodiment, the CDRs of the same user are associated with the DPI service data, and the occupation situation of various services on the wireless resources is determined by analyzing the associated CDRs and DPI service data, so that the occupation situation of the wireless resources is more accurately determined according to the service dimensions, and the resource energy efficiency difference of the services is mastered.

One embodiment of associating CDRs for the same subscriber with DPI traffic data is described below in conjunction with figure 2.

Figure 2 illustrates a flow diagram of one embodiment of associating CDRs for the same subscriber with DPI traffic data. As shown in fig. 2, on the basis of the embodiment shown in fig. 1, step S104 in this embodiment includes:

step S2042, associate the DPI service data with the IMSI of the user.

Take the example of assigning IMSI to service data. The process of assigning the IMSI to S1-U service data is shown in FIG. 3, and an S1-U interface of EPC is collected through a probe and TCP/IP and GTP-U data are analyzed, wherein the TCP/IP data are service plane data of a user; acquiring an S1-MME interface of the EPC through a probe and analyzing GTP-C and S1-MME signaling data, wherein S1-MME signaling carries the IMSI of a user; and (4) acquiring an S11 interface of the EPC through the probe and simultaneously analyzing GTP-U data and GTP-C data. The GTP-U and the GTP-C both comprise a tunnel identification field of a GTP process, and the IMSI of the user can be given to each TCP/IP process record of DPI service data of the user by matching the tunnel identification field of the GTP protocol.

Step S2044, associate the CDR with the IMSI of the user.

Take the example of assigning the IMSI to radio resource data. The process of assigning the IMSI to the radio resource data is illustrated in fig. 4, and the radio resource data is characterized using the subscriber's radio call record CDR. The user wireless call record and the S1-MME interface need to collect five fields of MME _ Group _ ID, MME _ Code, eNBID, MME _ UE _ S1AP _ ID and eNB _ UE _ S1AP _ ID, wherein the S1-MME interface collects the user identifier IMSI at the same time. Each piece of data of the user wireless call record includes five fields, namely, MME _ Group _ ID, MME _ Code, eNBID, MME _ UE _ S1AP _ ID, and eNB _ UE _ S1AP _ ID, and the signaling connection of S1-MME also includes the above five fields and the user identifier IMSI. Wherein, MME _ Group _ ID and MME _ Code identify the only MME; eNBID identifies a unique base station; MME _ UE _ S1AP _ ID, eNB _ UE _ S1AP _ ID identify unique one time S1AP connection under the base station, each S1AP connection of S1-MME collects user identification IMSI. Through matching of five fields of MME _ Group _ ID, MME _ Code, eNBID, MME _ UE _ S1AP _ ID, and eNB _ UE _ S1AP _ ID, the user wireless call record can be associated with S1-MME interface data, thereby giving the IMSI to the user wireless call record data.

Preferably, the IMSI of the user may be assigned to wireless data such as an MR measurement report to perform multidimensional data analysis.

Step S2046, the CDRs associated with the same IMSI are associated with DPI service data.

For example, by assigning the user identifier IMSI to the radio resource data and the service data, the CDR of the same IMSI can be associated with the DPI service data by matching the user identifier IMSI. Each wireless resource record of the user can be associated to a corresponding business process record; each service record of the user can be associated to the corresponding wireless resource record.

In the above embodiment, the wireless resource data and the service data of the same user are associated together by the IMSI of the user, so as to facilitate subsequent data analysis.

How to analyze the associated CDR and DPI service data to determine the occupation of wireless resources by various types of services is described below with reference to fig. 5 to 7.

The method for determining the wireless resource occupation by the evaluation service mainly comprises two processes: firstly, determining how to evaluate wireless resources, and mapping the wireless resources into indexes or field statistics; the second is to determine how to allocate the radio resources to different services for analysis.

The services include various mobile phone applications such as instant messaging, web portals, navigation, video, search, shopping, games, music, and the like. The radio resources include radio control resources, radio access resources, and radio traffic resources. The wireless control resource is mainly related to the wireless connection duration, so that the wireless control resource can be determined by the connection duration of the wireless call record of the user; the wireless access resource is directly related to the access times of wireless connection, so that the access times can be determined by the connection triggering times of the wireless call records of the user; the wireless service resource is directly related to the number of Physical Resource Blocks (PRBs) consumed by the wireless connection, and therefore can be determined by the number of PRBs recorded by the wireless call of the user.

Since a single or multiple services may be carried by a single radio connection of a user, evaluating radio resources using connection data of a user's radio call record, etc., requires allocating resources of the single connection to different services. Here, the allocation is performed by using methods such as time length or flow rate proportion and maximum value matching.

Fig. 5 shows a flow chart of evaluating the occupation of radio control resources by traffic. As shown in fig. 5, the RRC connection duration of the user wireless call record may be used to evaluate the usage of radio control resources by the service. Analyzing each user wireless call record, namely each RRC connection process, and recording the connection duration of the RRC connection; the DPI service data in each RRC connection is retrieved, the type, the flow and the duration of the service are identified, the RRC connection duration is distributed to different services according to the flow or the duration, the RRC connection duration occupied by different services is summarized, and therefore the occupation situation of each service on the RRC connection duration is obtained, and the service situation of the service on the wireless control resources is evaluated.

Fig. 6 shows a flow diagram of evaluating the occupation of radio access resources by a service. As shown in fig. 6, the usage of radio control resources by the service can be evaluated using the number of RRC connection triggers of the user radio call record. Analyzing each user wireless call record, namely each RRC connection triggering process, retrieving DPI service data in each RRC connection, extracting the service type of a first data packet, and giving the service type to the RRC connection triggering process, thereby summarizing and acquiring the times of triggering the RRC connection by each service, and evaluating the occupation condition of the service on wireless access resources. The specific flow is shown in fig. 6.

Fig. 7 shows a flow diagram of evaluating the occupation of wireless service resources by a service. As shown in fig. 7, the number of PRBs of the user's wireless call record can be used to evaluate the occupation of wireless service resources by the service. Analyzing each user wireless call record, namely each RRC connection process, and recording the number of occupied PRBs; and retrieving DPI service data in each RRC connection, identifying the type and the flow of the service, and proportionally allocating the PRB number of each RRC connection to different services according to the flow so as to obtain the occupation condition of each service to the PRB number, and summarizing the statistical conditions of all the RRC connections so as to evaluate the service condition of the service to the wireless service resources. The specific flow is shown in fig. 7.

In the above three embodiments, the evaluation field of the radio resource is confirmed, and the radio resource in each connection is matched according to the service. The occupation of the wireless control resource and the wireless access resource by the service can be determined while the occupation of the wireless service resource by the service is determined.
