Problems solved by technology

[0010] However, during the research and practice of the prior art, the inventor found that the prior art has the following problems: single-cell MBMS service scheduling (such as figure 2 As shown) is very different from multi-cell MBMS (MBSFN) scheduling: the scheduling information of PDSCH for single-cell MBMS service scheduling is transmitted on PDCCH, and the scheduling information of PMCH is transmitted on MSI (MCH Scheduling Information, multicast channel scheduling information) ; Therefore, the multi-cell MBMS scheduling method cannot be used in the single-cell MBMS scheduling. Considering the difference between the MBMS service and the unicast service, it is not suitable to dynamically schedule the MBMS service on the PDCCH of each subframe
[0011] Aiming at the technical problem that there is no technical solution to realize the scheduling process suitable for single-cell MBMS service in the related technology, no effective solution has been proposed yet

Embodiment 1

[0122] The scenario of the preferred embodiment 1 is that the MBMS semi-persistent scheduling is activated, assuming that the MBMS service semi-persistent scheduling has not been activated yet; Figure 9 It is a flow chart according to the preferred embodiment 1 of the present invention, such as Figure 9 As shown, this example includes the following steps:

[0123] In step S902, the base station eNB indicates S-MCCH configuration information through a system broadcast message.

[0124]The system broadcast message is an existing MBMS system message, such as SIB13 or SIB15. The S-MCCH is the MCCH corresponding to a single cell, and the configuration information is the subframe position information where the S-MCCH is located, such as by frame period, Designation of subframe offset, etc.

[0125] In step S904, the eNB indicates Gs-RNTI related configuration information through the S-MCCH.

[0126] The Gs-RNTI configuration information at least includes: the mapping relationsh...

Embodiment 2

[0140] The scenario of this embodiment is MBMS semi-persistent scheduling release; it is assumed that the MBMS service semi-persistent scheduling has been activated; Figure 10 It is a flow chart according to the second preferred embodiment of the present invention, such as Figure 10 As shown, this example includes the following steps:

[0141] The step is S1002, the base station eNB indicates S-MCCH configuration information through a system broadcast message.

[0142] The system broadcast message is an existing MBMS system message, such as SIB13 or SIB15. The S-MCCH is the MCCH corresponding to a single cell, and the configuration information is the subframe position information where the S-MCCH is located, such as by frame period, Designation of subframe offset, etc.

[0143] In step S1004, the eNB indicates Gs-RNTI related configuration information through the S-MCCH.

[0144] The Gs-RNTI configuration information at least includes: the mapping relationship between TMG...

Embodiment 3

[0158] The scenario of this embodiment is the update of semi-persistent scheduling information; assuming that the MBMS service semi-persistent scheduling has been activated, Figure 11 It is the flowchart of the third preferred embodiment of the present invention, such as Figure 11 As shown, the third preferred embodiment includes the following steps:

[0159] In step S1102, the base station eNB indicates S-MCCH configuration information through a system broadcast message.

[0160] The system broadcast message is an existing MBMS system message, such as SIB13 or SIB15. The S-MCCH is the MCCH corresponding to a single cell, and the configuration information is the subframe position information where the S-MCCH is located, such as by frame period, Designation of subframe offset, etc.

[0161] In step S1104, the eNB indicates Gs-RNTI related configuration information through the S-MCCH.

[0162] The Gs-RNTI configuration information at least includes: the mapping relationship...

Abstract

The present invention provides a scheduling method and device for MBMS, multimedia multimedia multimedia multimedia broadcasting business in a single community.RNTI configuration information and / or second RNTI configuration information.The sub -frame position where PDCCH is located, the second RNTI is used to identify the dynamic scheduling method to dispatch the single community MBMS, and the second RNTI configuration information is used to indicate the TMGI corresponding to the second RNTI;The MBMS business uses the above technical solution to achieve a single community MBMS business scheduling.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a scheduling method and device for a single-cell Multimedia Broadcast and Multicast Service (MBMS for short). Background technique [0002] With the rapid development of the Internet and the popularization of large-screen multifunctional mobile terminals, a large number of mobile data multimedia services and various high-bandwidth multimedia services have emerged, such as video conferencing, TV broadcasting, video on demand, advertisements, online education, interactive games, etc. On the one hand, it meets the multi-service requirements of mobile users, and at the same time brings new business growth points for mobile operators. These mobile data multimedia services require multiple users to receive the same data at the same time. Compared with general data services, they have the characteristics of large data volume, long duration, and delay sensitivity. [0003] In order to...
