Problems solved by technology

[0017] However, the existing TS36.300 standard only describes the cell reselection process for UEs in the Idle state that are receiving EMBMS. For details related to the continuity of EMBMS reception, such as: receiving EMBMS characteristic information, UEs going out of the MBSFN domain may cause The transmission type conversion, etc., did not give a clear technical solution
[0018] To sum up, the prior art does not provide a technical solution for continuously receiving EMBMS when the Idle state UE receiving EMBMS crosses the MBSFN boundary. poor quality

Embodiment Construction

[0046] Embodiments of the present invention provide a method, system, and device for transmitting EMBMS, which are applied in the process of receiving EMBMS by a user terminal in an idle state using resources in a multi-cell point-to-multipoint mode in a multicast broadcast single frequency network. To improve the receiving quality of EMBMS.

[0047] Based on the characteristics of the MBSFN area - the multi-cell energy combination characteristics of MBSFN and the characteristics of the boundary cell type (TOC or Reserved cell) of the MBSFN domain, it can be found that when the UE in the Idle state receiving EMBMS, from image 3 When the central area (TAC coverage area) of the shown MBSFN area moves to the outside, it may enter a common cell that does not provide EMBMS. This is a basic scenario on the EMBMS / Unicast hybrid carrier (or shared carrier).

[0048] In the shared carrier scenario, for the continuity requirements when the UE receiving EMBMS crosses the MBSFN boundary ...

Abstract

The invention discloses a method, a system and a device for transmitting an enhanced type multimedia broadcast multicast service (EMBMS), which are applied to improving the EMBMS receiving quality of a user terminal. A method for receiving the EMBMS is applied to the process of receiving the EMBMS by the user terminal in an idle state by using multi-cell point-to-multipoint mode resources in a multicast broadcast single frequency network, and comprises the following steps that: the user terminal sends an EMBMS request message to a network side; the user terminal receives configuration information of single-cell point-to-multipoint mode resources established by the network side for transmitting the EMBMS; and the user terminal acquires the new resources allocated by the network side for transmitting the EMBMS, and uses the resources to receive the EMBMS. The method, the system and the device are mainly applied to transmitting and receiving the EMBMS in the multicast broadcast single frequency network, improving the EMBMS receiving quality, and ensuring the EMBMS receiving continuity.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and device for transmitting Enhanced Multimedia Broadcast Multicast Service (EMBMS, Enhanced Multimedia Broadcast Multicast Service). Background technique [0002] The Long Term Evolution (LTE, Long Term Evolvement) standard is an evolution standard based on the Universal Terrestrial Radio Access Network (UTRAN, Universal Terrestrial Radio Access Network) formulated by the 3GPP organization. The EMBMS provided by it can support higher-speed multimedia data transmission and more Good quality of service, its architecture such as figure 1 as shown, figure 1 The SGmb interface and SGi-mb interface described in are between the enhanced broadcast / multicast service control (eBM-SC, enhanced Broadcast / Multicast Service Control) node and the core network multimedia broadcast multicast service (MBMS, Multimedia BroadcastMulticast Service) node MBMS2 interf...
