Description

 MBMS measuring method and device

Technical field

 The present invention relates to the field of wireless communication technologies, and in particular, to an MBMS measurement method and apparatus. Background technique

 The measurements in the Long Term Evolution (LTE) system mainly refer to mobility measurements in the connected state. The measurement configuration is sent to the user equipment (User Equipment, UE) by the network side (such as the base station) through the Radio Resource Control (RRC) connection reconfiguration message (RRC connection reconfiguration), and the frequency to be measured is specified in the measurement configuration. Point or cell, and measured indicators (including Reference Signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ)); the UE performs measurement according to the measurement configuration, and the measurement report (Measure Report) is reported to the network side. The measurement report includes a periodic report or an event trigger report.

 In order to reduce the operation and maintenance cost of the network and reduce the amount of road test work, the Minimize Driver Test (MDT) was introduced. MDT refers to the automatic collection of measurement results through the network side and the UE side to assist in network problem analysis. According to the reporting method of MDT results, MDT is further divided into:

 1) Logged MDT (Log MDT): The UE obtains the logged MDT configuration in the RRC connected state through dedicated signaling. After the UE enters the idle state, the MDT measurement result is collected. The subsequent connection state reports the collected result to the network side. .

 2) Immediate MDT: The MDT measurement in the connected state is the same as the above. This includes the UE side collecting MDT measurement amount and the network side statistical MDT measurement amount.

The LTE system introduces MBMS (Multimedia Broadcast/Multicast Service) technology in Rel-9, and its main function is to implement broadcast and multicast services in the LTE system. Currently, the MBMS is generally provided in the form of a broadcast, and each cell may have several subframes to transmit the MBMS service. The UE may receive the MBMS service by receiving the subframes, and the UE may receive the MBMS subframe in the idle state or the connected state, where the eNB may It is not necessary to know which UEs are receiving. Of course the eNB also It can be learned by initiating the counting process which UEs in the connected state are receiving or interested in receiving MBMS services.

 The MBMS service of the LTE system adopts the Multimedia Broadcast Multicast Service Single Frequency Network (MBSFN) technology, which requires simultaneous transmission of identical waveforms from multiple cells. In this way, the UE can treat multiple MBSFN cells as one large cell. Furthermore, the UE will not only be subject to inter-cell interference transmitted by neighboring cells, but will also benefit from the superposition of signals from multiple MBSF cells. The multiple cells that transmit the same waveform are called an MBSFN area, and multiple Physical Multicast Channels (PMCHs) can be configured in one MBSFN area, and each PMCH can carry several MBMS business. Each PMCH can have the same modulation coding mode or different modulation coding mode.

 At present, the measurement of the LTE system only supports the measurement of the Cell-specific Reference Signals (CRS), and does not support the measurement of the MBSFN reference signal, so that the network side cannot learn the transmission of the MBMS service on the UE side during the working process. Performance, unable to optimize the transmission of MBMS services. Summary of the invention
