Problems solved by technology

[0022] However, in the existing LTE system, because the network side cannot obtain the MBMS reception status of the UE in the connected state, the network side cannot configure a reasonable measurement gap and DRX cycle for the UE, so the normal reception of MBMS by the UE cannot be guaranteed.

Embodiment Construction

[0043] The embodiment of the present invention provides an information acquisition method and device, which are used to realize that the network side obtains the UE's reception information of the MBMS in the connected state in time, so that the network side can reasonably configure parameter information such as measurement Gap and DRX time for the UE , to ensure the normal reception of the MBMS by the UE.

[0044] 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.

[0045] 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 t...

Abstract

The invention discloses an information acquisition method and an information acquisition device. Through the method and device, a network side can timely acquire multimedia broadcast multicast service (MBMS) receiving information of user equipment (UE) in a connection state, so that the network side can configure reasonable information of measurement gap, discontinuous reception (DRX) time and other parameters for the UE, and the UE can normally receive the MBMS. The information acquisition method comprises the following steps that: a base station acquires a multimedia broadcast multicast service (MBMS) report control element (CE) and a logic channel identifier (LCID) of the MBMS report control element (CE) which are sent by the user equipment (UE), wherein the MBMS report control element (CE) contains a media access control element (MAC CE) of the MSMS receiving information of the UE; and the base station analyzes the MBMS report control element (CE) by using the information structure of the CE corresponding to the LCID and determining the MBMS receiving information of the UE.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information acquisition 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 o...
