Embodiment 1

[0056] The application scenario of this example is that the UE periodically initiates the feedback process, and the period is selected by the UE itself.

[0057] figure 2 It is a flowchart of Embodiment 1 of the method for UE periodically initiating feedback according to the present invention, such as figure 2 As shown, the method for UE periodic feedback in this example includes the following steps:

[0058] Step 101: The UE selects a reporting period, and in each reporting period, the UE sends a reception status report to the network side;

[0059] The reporting period may be a period defined in the specification. Preferably, the period may be: one or more MCCH modification periods, or one or more multicast channel scheduling periods (MSP, MCHS scheduling Period); different UEs The same or different feedback periods can be selected; in order to reduce the number of UEs that initiate feedback at the same time, in the feedback period, the UE can randomly select the time to send the...

Embodiment 2

[0075] The scenario in this example is that the UE sends uplink feedback when a specific event occurs, such as Figure 4 As shown, the method for UE periodic feedback in this example includes the following steps:

[0076] Step 201: The UE selects an event that triggers the reporting of the receiving status, and when the event occurs, the UE sends a receiving status report to the network side;

[0077] The trigger event includes at least one of the following: session start, session end, bearer change, cell update, cell handover;

[0078] The UE may be in an RRC connected state or an RRC idle state;

[0079] The network side generally includes eNB and MCE.

[0080] For the UE in the RRC connected state, the feedback information is generally sent through RRC signaling or MAC CE signaling; when a reporting event occurs, if the UE has available uplink resources, the UE sends the feedback information, otherwise the UE sends a scheduling request (SR, Schedule Request) Or a Buffer Status Repor...

Embodiment 3

[0092] The scenario in this example is that the network side sends a feedback request indication, and the UE sends feedback information according to the above indication, such as Figure 5 As shown, the method for requesting UE feedback from the network side in this example includes the following steps:

[0093] Step 301: The network side sends a feedback request indication to the UE through an RRC message or a MAC CE message.

[0094] Preferably, the RRC message may be an MCCH message or a system message; the RRC message may be a single RRC message or an IE;

[0095] The feedback request indication information generally includes MBMS service identification ID or MBMS session identification ID or bitmap information indicating the MBMS session; in order to reduce the number of UEs sending feedback at the same time, the feedback request indication information generally also includes a probability factor.

[0096] The UE may be in the RRC connected state or the RRC idle state; for the RRC...

Abstract

The invention discloses a realization method and a system for sending and receiving a state report by a UE (User Equipment) in an MBMS (Multimedia Broadcast Multicast Service). The realization method comprises the following steps of: actively initiating a feedback process by the UE or sending a feedback request indication to the UE by a network side within a certain period or at the occurrence of a trigger event; sending feedback information to the network side by the UE according to such indication; and counting a UE receiving state by the network side according to the feedback information of the UE. The invention also discloses a system for sending the MBMS and receiving the state report by the UE. In the invention, the UE can send and receive the state report under the condition of a plurality of MCCHs (Multiple Control Channel), the correct statistics on the number of the UE is realized, and requirements on activating or deactivating MBSFN (Multimedia Broadcast System Frame Number) transmission by the network side are satisfied.

Description

Technical field [0001] The invention relates to a technology for reporting user equipment (UE, User Equipment) service information in a multimedia broadcast multicast service (MBMS, Multimedia Broadcast Multicast Service) system, in particular to a multimedia broadcast multicast service user equipment receiving status report The sending method and system. Background technique [0002] In order to effectively use mobile network resources, the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) proposed the MBMS service. The MBMS service is a technology that transmits data from one data source to multiple target mobile terminals. The sharing of network (including core network and access network) resources improves the utilization of network resources, especially air interface resources. [0003] In the Long Term Evolution (LTE, Long Term Evolution) system, the user equipment (or terminal) is notified that a certain MBMS service is about to change. These cha...
