Description

Issuing method of reporting intention information, core network equipment and wireless access network equipment

Technical Field

The invention relates to the field of communication, in particular to a reporting intention information issuing method, core network equipment and wireless access network equipment.

Background

With the development of wireless multimedia services, the demand for high data rate and user experience is increasing, and thus higher requirements are placed on the system capacity and coverage of the conventional cellular network. On the other hand, the popularity of applications such as social networking, near-distance data sharing, local advertising, etc. has increased the need for people to know and communicate with people or things of interest nearby (proximity services). Given the significant limitations of conventional cell-based cellular networks in terms of high data rates and support for proximity services, Device-to-Device (D2D) technology, representing a new direction for future communication technology development, has emerged. The application of the D2D technology can reduce the burden of the cellular network, reduce the battery power consumption of the user equipment, increase the data rate, and improve the robustness of the network infrastructure, and well meet the requirements of the high data rate service and the proximity service.

The D2D technology can operate in licensed or unlicensed bands, allowing multiple D2D capable User equipments (D2D User Equipment, abbreviated as D2D UEs) to perform direct discovery/direct communication with or without network infrastructure. There are three main application scenarios of D2D: 1) the UE1 and the UE2 perform data interaction under the coverage of a cellular network, and user plane data does not pass through a network infrastructure, as in mode 1 of fig. 1; 2) UE relay transmission in weak/no coverage areas, such as mode 2 in fig. 1, allows a UE4 with poor signal quality to communicate with the network through a UE3 with network coverage nearby, which can help operators to extend coverage and increase capacity; 3) in the event of an earthquake or an emergency, the cellular network cannot work normally, and direct communication between devices is allowed, such as mode 3, UE5, control plane and user plane between UE6 and UE7 in fig. 1, and one-hop or multi-hop data communication is performed without passing through the network infrastructure.

D2D technologies generally include D2D discovery technology and D2D communication technology: 1) D2D discovery techniques refer to techniques for determining/determining that two or more D2D user devices are in proximity to each other (e.g., within D2D direct communication enabled range) or that a first user device is in proximity to a second user device; 2) the D2D communication technology refers to a technology in which some or all of communication data between D2D user devices may be communicated directly without passing through a network infrastructure.

The D2D communication can multiplex cellular communication resources, and under the scene of cellular network coverage, the D2D communication resources are generally scheduled and allocated by the base station, so that the resource multiplexing efficiency can be improved, and the control of the network side on the D2D communication and the interference coordination effect between the D2D communication and the cellular communication are ensured. For the same UE, if it supports D2D functionality, it is possible to simultaneously perform D2D communication with another D2D UE and cellular communication with a base station.

Meanwhile, in order to reduce the cost and complexity of manual Drive Test by using dedicated devices by operators, Third Generation Partnership project (3 GPP) organizations start to introduce Minimization of Drive Test (MDT) function in Release 10(Release-10) of Universal Terrestrial Radio Access Network (UTRAN) and Evolved Universal Terrestrial Radio Access Network (E-UTRAN) systems, and an architecture diagram of MDT is shown in fig. 2.

The UTRAN includes a base station (Node B) and a Radio Network Controller (RNC), and a core network (CoreNetwork, abbreviated as CN) corresponding thereto includes a Home Subscriber Server (HSS), a Mobile Switching center Server (MSC Server), a Serving GPRS Support Node (SGSN), and the like. The E-UTRAN includes an evolved node b (eNB), and a corresponding core network CN includes a home subscriber server HSS, a Mobile Management Entity (MME), and the like.

The MDT function utilizes a User Equipment (User Equipment, abbreviated as UE) to automatically collect measurement information And reports the measurement information to a Radio Access Network (RAN) through a Control Plane (Control Plane) signaling, And reports the measurement information to a Tracking Collection Entity (TCE) of an Operation And Maintenance system (Operation And Maintenance, abbreviated as OAM) through a Radio Access Network (RNC) And an eNB for a UTRAN system, And then through a Radio Access Network. The application scenarios of the MDT mainly comprise the aspects of coverage optimization, capacity optimization, mobility optimization, common channel parameter optimization and the like.

MDT in the related art supports management-based MDT (managed based MDT) and signaling-based MDT (signaling-based MDT). Taking E-UTRAN system as an example, the management-based MDT activation procedure is usually that OAM sends a message to eNB to activate MDT measurement of some UEs, eNB selects UE according to received Area (Area) information and sends MDT configuration information to the selected UE. Taking E-UTRAN system as an example, the signaling-based MDT activation process generally includes that OAM sends a message to HSS to activate MDT measurement of a certain UE, HSS sends MDT configuration information of the UE to MME, MME sends MDT configuration information of the UE to eNB, and eNB finally sends MDT configuration information to the UE. Signaling-based MDT typically specifies a UE with an International Mobile Subscriber Identity (IMSI) or an International Mobile Station Equipment Identity (IMEI), or plus regional information to limit UE selection.

In the related art, MDT supports the UE to perform MDT measurement in a CONNECTED (CONNECTED) state and an IDLE (IDLE) state, wherein MDT performed in the CONNECTED state is referred to as immediate MDT (immediate MDT), and MDT performed in the IDLE state is referred to as log MDT (logged MDT). Immediate MDT means that the UE carries out MDT measurement in a connection state according to MDT configuration information, reports the measurement information to a wireless access network in time and reports the measurement information to the TCE through the wireless access network. The log MDT means that the UE carries out MDT measurement in an idle state according to the MDT configuration information and stores the measurement information, and reports the MDT measurement information to the wireless access network when the UE subsequently enters a connection state and reports the MDT measurement information to the TCE through the wireless access network.

The UE may be configured with two sets of independent configuration information, immediate MDT configuration information and log MDT configuration information. Both MDT configuration information is configured by the network to the UE when the UE is in a connected state. The two types of MDT measurement configurations also differ according to the two different types of content, immediate reporting and log reporting. The MDT measurement method includes the MDT application range, which can be represented by a cell list or a TA list, UE flag information (only used for UE-based tracking in UMTS), MDT measurement content, and for immediate MDT, a reporting trigger event, a reporting interval, and a reporting number are also required. For the log MDT, then the logging interval is included, the log configuration duration.

Meanwhile, in the related art, when the management-based MDT is adopted, the base station needs to select a proper user according to the willingness of the user to perform MDT measurement and the area parameter in the MDT configuration information to perform MDT measurement and report, and at present, no technology exists for recording and reporting the D2D related information experienced by the base station according to the willingness of the user, so that a network side can select a proper user according to the willingness of different users and the area range where the user is located to perform D2D related measurement and report.
