FIELD OF THE INVENTION
The present invention relates to the field of communications and in particular to a method and system for collecting terminal measurement data. FUNDAMENTALS OF THE INVENTION
In some communication systems, eg Global System for Mobile Communications (GSM), Wideband Code Division Multiple Access Wireless (WCDMA), Code Division Multiple Access (CDMA, Code Division Multiple Addressing) and Worldwide Interoperability for Microwave Access (Wimax) to ensure normal communication over the network, some data, eg network element data, needs to be collected.
Universal Mobile Telecommunication System (UMTS) is a third generation mobile communication system that adopts WCDMA air interface technology. The UMTS system is generally called the WCDMA communication system.
For example, FIG. 1 is a schematic structural diagram of a UMTS in the prior art. The Universal Mobile Telecommunication System (UMTS) adopts a structure similar to a second-generation mobile communication system, which includes a radio access network (Radio Access Network, RAN) and a core network (Core Network, CN) . The radio access network handles all radio-related functions and the CN handles all voice calls and data connections in the UMTS system and implements switching and routing functions with external networks. Logically, the CN is divided into a circuit switched domain (Circuit Switched Domain, CS) and a packet switched domain (Packet Switched Domain, PS).
The CN core network includes an MSC/VLR, a Serving GPRS Support Node (SGSN), an HLR, a Gateway Mobile-services Switching Center (GMSC) and a GPRS Gateway Support Node (GGSN). The core network can be connected to an external network (External Network) through GMSC or GGSN. For example, the core network can be connected to a public land mobile network (PLMN), a public switched telephone network (PSTN), or an integrated services digital network (ISDN). , Integrated Services Digital Network) through the GMSC; and can be connected to the Internet INTERNET through the GGSN.
The UMTS system includes a Universal Terrestrial Radio Access Network (UTRAN), a CN and a user equipment (User Equipment, UE).
FIG. 2 is a schematic structural diagram of a UTRAN in the prior art. UTRAN is a terrestrial radio access network and includes one or more radio network subsystems (RNS). An RNS includes a radio network controller (RNC) and one or more base stations (NodeB). The interface between the RNC and the CN is an lu interface, and the NodeB and RNC are connected via a lub interface. Within the UTRAN, radio network controllers (RNC) are interconnected through a lur interface, which implements a connection through the use of a direct physical connection between the RNCs or through the use of a transport network. The RNC allocates and controls radio resources from the NodeB linked or related to the RNC. NodeB implements data stream conversion between the lub interface and a Uu interface and also partially manages the radio resources.
The NodeB is a base station (or radio transceiver) in a WCDMA system, which includes a radio transceiver and a baseband processing unit. The NodeB interconnects with the RNC through a standard lub interface and mainly implements Uu interface physical layer protocol processing. The NodeB's main functions include spectrum spread, modulation, channel coding and agglomeration, demodulation, and channel coding, as well as manual conversions between baseband signals and radio frequency signals.
The RNC is a radio network controller that controls radio resources of the UTRAN. The RNC mainly implements such functions as connection setup and disconnection, transfer, macrodiversity combination, and radio resource management control.
To maintain the competitiveness of future networks, 3GPP introduces a brand new network evolution architecture to meet the patent application requirements regarding the mobile network in the next ten years or even more, which includes system architecture evolution (SAE, System Architecture Evolution) and long-term evolution (LTE, Long Term Evolution) of the access network. The evolved access network is called the Evolved Universal Terrestrial Radio Access Network (E-UTRAN). The goal of network evolution is to provide a fully IP-based network with short delay, high data rate, large system capacity, wide coverage, and low cost. Since this is a brand new network architecture, all nodes, functions and procedures subject to the current architecture undergo substantive changes.
An evolved packet core network architecture can be shown in FIG. 3, which includes three logical function entities, namely, a mobility management entity (MME), a service SAE portal (Serving SAE GW) and a packet data network (PDN) SAE portal (Packet Data Network) SAE GW).
The MME is responsible for managing mobility in a control plan, including user context and mobility state management and temporary allocation of user identity, corresponding to a control plan of a service GPRS support node (SGSN) in a current GPRS/UMTS system.
The service SAE portal is responsible for initiating radio calls to downlink data in an idle state and managing and storing carrier parameters and intra-network routing information, corresponding to an SGSN data plane and a portal support node GPRS (GGSN, Gateway GPRS Support Node) in the current GPRS/UMTS system.
The PDN SAE GW serves as a user piano attachment point between different access systems.
The Policy and Charging Rule Function (PCRF) entity is used for policy decision and control and flow charging control.
Home Subscriber Server (HSS) is used to store user subscription information.
A network structure of the E-UTRAN is shown in FIG. 4, where a Mobility Management Entity (MME) and an eNB are connected through an Sl-MME interface, a service SAE portal (Serving SAE GW) and an eNB are connected through an interface Sl-U, and two eNBs are connected via an X2 interface.
Conventional network optimization is based on trigger test data. A trigger tester is used to collect data such as the level and quality of a network and the data is analyzed to discover issues related to network coverage, capacity, QoS and mobility. In this way, network optimization is specifically implemented in the affected areas.
As the scale of the network grows constantly, it becomes increasingly difficult to implement optimization relying solely on experience. Also, due to the restriction of the Trigger Test route, the Trigger Test data may not reveal all network problems.
Consequently, operators need automatic network optimization. Automatic network optimization is able to minimize an operator's OPEX, maximizing network utilization at minimal equipment cost, reducing the experience requirement and dependence on network optimization personnel, and alleviating the workload of network personnel. network optimization.
To reduce conventional trigger tests that require a large proportion of manual labor and to collect data more efficiently, 3GPP is considering a replacement of automatic reporting of necessary network optimization parameters with common commercial terminals for conventional manual collection of data from drive tests (terminal measurement data). This automatic reporting of terminal measurement data by common commercial terminals can be used as a basic MDT (Minimization Drive Test) method to collect drive test data (terminal measurement data).
FIG. 5 is a schematic flowchart of a method of tracking user equipment in the prior art. An element management system (EMS) can broadcast parameter settings to track all network element nodes in the system in order to implement signaling tracking on a specific user or device.
Network element nodes in the network transmit recorded trace data to a Trace Data Collection Entity. After the entity collects signaling trace data from a specific user, failures and problems in the network can be accessed and diagnosed according to the analysis of the trace data.
501. An EMS transmits a Trace Session Activation message to an HSS or an MME.
The Tracking Session Activation message is used to activate a signaling tracking procedure for a specific user or device, and carries tracking configuration parameters that include International Mobile Subscriber Identity (IMSI) or International Identity of mobile equipment (IMEI), trace reference (Trace Reference Identity), trigger events (Triggering Events), depth of trace (Trace Depth), list of NE types to trace, list of interfaces (List of Interfaces) and IP Address of Trace Data Collection Entity.
502-504. HSS stores trace configuration parameters. When a user to be tracked accesses the network, the user transmits an Attach Request to the network, and transmits an Update Location Request to the HSS to update its location information.
505. The HSS checks whether the user needs tracking and, if so, passes the tracking configuration parameters to the MME using an Update Location Answer.
506. The MME stores the trace configuration parameters, initiates a user-specific trace logging session, and passes the trace configuration parameters to a NodeB using an Initial Context Setup Request. .
The NodeB stores the trace configuration parameters and initiates the specific trace logging session for the user.
This method, however, only implements user-specific signaling data tracking for network elements on the network side and may not implement data collection and analysis at a user terminal. This limits the effects of evaluating and diagnosing network failures, and may not determine the radio environment in which the user is located. As a result, potential issues in network coverage, capacity, QoS and mobility may go undetected. SUMMARY OF THE INVENTION
