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 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 (MCHScheduling Information, multicast channel scheduling information); Therefore, the method of multi-cell MBMS scheduling cannot be used in single-cell MBMS scheduling. Considering the difference between MBMS services and unicast services, it is not suitable to dynamically schedule MBMS services 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 first preferred embodiment is that MBMS semi-persistent scheduling is activated, assuming that the MBMS service semi-persistent scheduling has not been activated; Picture 9 It is a flowchart according to the first preferred embodiment of the present invention, such as Picture 9 As shown, this example includes the following steps:

[0123] 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 location information of the subframe where the S-MCCH is located, such as through frame period, Specify the subframe offset, etc.

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

[0126] The Gs-RNTI configuration information includes at least: a mapping relationship betwe...

Embodiment 2

[0140] The scenario of this embodiment is the release of MBMS semi-persistent scheduling; it is assumed that the MBMS service semi-persistent scheduling has been activated; Picture 10 Is a flowchart according to the second preferred embodiment of the present invention, such as Picture 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 location information of the subframe where the S-MCCH is located, such as through frame period, Specify the subframe offset, etc.

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

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

Embodiment 3

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

[0159] 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 location information of the subframe where the S-MCCH is located, such as through frame period, Specify the subframe offset, etc.

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

[0162] The Gs-RNTI configuration information includes at least: a mapping relationshi...

Abstract

The invention provides a scheduling method and apparatus for a multimedia broadcast and multicast server (MBMS) of a single cell. The method comprises: a point-to-multipoint S-MBMS control channel (MCCH) message, sent by a base station, of a single cell is received, wherein the S-MCCH message carries first radio network temporary identifier (RNTI) configuration information and / or second RNTI configuration information, the first RNTI is used for identifying scheduling of a single cell MBMS by using a semi-static scheduling way and the first RNTI configuration information is used for indicating a temporarily mobile group identifier (TMGI) corresponding to the first RNTI and a position of a sub frame where a physical downlink control channel (PDCCH) using the first RNTI for scrambling is located, and the second RNTI is used for identifying scheduling of a single cell MBMS by using a dynamic scheduling way and the second RNTI configuration information is used for indicating a TMGI corresponding to the second RNTI; and according to scheduling information received by the PDCCH, an MBMS service needed by the PDSCH. According to the technical scheme, MBMS scheduling of a single cell is realized.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a single-cell Multimedia Broadcast and Multicast Service (Multimedia Broadcast and Multicast Service, referred to as MBMS) scheduling method and device. 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, advertising, online education, interactive games, etc. This aspect meets the multi-service needs 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 ordinary data services, they have the characteristics of large data volume, long duration, and time delay s...
