Problems solved by technology

[0022] In the existing LTE system, the UE cannot report its reception of MBMS to the network side, so that the network side cannot configure a reasonable measurement gap and DRX cycle for the UE according to the UE's reception of MBMS.
For example, if the measurement Gap configured by the network side for the UE conflicts with the time when the UE receives the MBMS service, the MBMS service will be interrupted because the UE cannot receive data during the measurement Gap period. Normal reception of MBMS

Embodiment Construction

[0038] The embodiment of the present invention provides an information reporting method and device, which are used to realize the network side to obtain the MBMS reception status reported by the UE in the connection state in time, so that the network side can configure reasonable parameter information such as measurement Gap and DRX time for the UE , and ensure the normal reception of the MBMS by the UE.

[0039] In the embodiment of the present invention, the UE can receive the MBMS no matter it is in the connected state or in the idle state.

[0040] Since the UE in the connected state needs to measure the signal strength of the neighboring cell, there will be a 6ms measurement gap every 40ms or 80ms. During the measurement gap period, the UE cannot receive data, so it is necessary to avoid MBMS subframes that the UE needs to receive during the measurement gap period. , and outside the Gap measurement period, transmit the MBMS subframes that the UE needs to receive, so as to...

Abstract

The invention discloses an information reporting method and an information reporting device, which are used for enabling a network to instantly acquire a multimedia broadcast multicast service (MBMS) receiving state reported by user equipment (UE) in a connected state, so that the network can configure rational parameter information such as time for measuring Gap and DRX in the UE and guarantee that the UE receives the MBMS normally. The information reporting method provided by the invention comprises the steps that: the UE generates the MBMS receiving state according to the receiving condition of the MBMS sent by the network; and the UE reports the currently generated MBMS receiving state to a base station.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information reporting method and device. Background technique [0002] The MBMS in the Long Term Evolution (LTE, Long Term Evolution) system is also called an evolved multimedia broadcast multicast service (eMBMS, evolved MBMS), and its main function is to implement broadcast and multicast services in the LTE system. [0003] Multimedia Broadcast Multicast Service Single Frequency Network (MBSFN, MBSFN Transmission) is a simulcast transmission technology that simultaneously transmits consistent signal waveforms in multiple cells. Such as figure 1 As shown, several basic concepts related to MBMS are introduced as follows: [0004] MBSFN Synchronization Area (MBSFN Synchronization Area): An area where all evolved base stations (eNodeBs) can obtain synchronization and perform MBSFN transmission. [0005] MBSFN area (MBSFNArea): An MBSFN area includes a group of ...
