Embodiment approach

[0072] A preferred implementation method of the present invention is provided below, comprising the following steps:

[0073] 1. The MCE notifies the base station to report the MCS assisted determination information (ie indication information) of the specified service;

[0074] 2. The base station notifies the MCE of the MCS assistance determination information of the specified service;

[0075] 3. The MCE judges the MCS corresponding to the multimedia broadcast multicast according to the MCS auxiliary determination information reported by the base station;

[0076] 5. The MCE notifies the base station to specify the MCS for the multimedia broadcast multicast.

[0077] The following are detailed examples of several signaling configurations, as the preferred solution of this embodiment:

Embodiment 1

[0079] Figure 7 Shows a schematic diagram of multimedia broadcast multicast service MCS determination (embodiment 1);

[0080] 1. The multimedia broadcast multicast coordinating entity (MCE) notifies the base station to report MCS assistance determination information. The multimedia broadcast multicast coordinating entity (MCE) can specify corresponding reporting content. The reported content can be, but not limited to, one of the following:

[0081] ●Specify the length of time

[0082] ● Specify the cycle of MCS assistance to determine the message

[0083] ●Designated multimedia broadcast multicast service

[0084] ●Designated business type

[0085] ●Designated quality of service (QoS)

[0086] 2. After receiving the MCS assistance determination request message from the Multimedia Broadcast Multicast Coordination Entity (MCE), the base station sends the MCS assistance determination information of the designated multimedia broadcast multicast service that meets the requ...

Embodiment 2

[0098] Figure 8 Shows a schematic diagram of multimedia broadcast multicast service MCS determination (embodiment 2);

[0099] 1. The multimedia broadcast multicast coordinating entity (MCE) notifies the base station to report MCS assistance determination information. The multimedia broadcast multicast coordinating entity (MCE) can specify corresponding reporting content. The reported content can be, but not limited to, one of the following:

[0100] ●Specify the length of time

[0101] ● Specify the cycle of MCS assistance to determine the message

[0102] ●Designated business

[0103] ●Designated business type

[0104] ●Designated quality of service (QoS)

[0105] 2. After receiving the MCS assistance determination request message from the Multimedia Broadcast Multicast Coordination Entity (MCE), the base station sends the required MCS assistance determination information to the Multimedia Broadcast Multicast Coordination Entity (MCE) according to the cell range.

Abstract

The invention provides a method for determining the MCS of an MBMS, which comprises the following steps that: an MCE receives indication information from a base station; and the MCE determines the MCS according to the indication information. The invention also provides the MCE, which comprises a receiving module for receiving the indication information from the base station and a determination module for determining the MCS according to the indication information. In the invention, as the MCE is notified of the MCS auxiliary determination information of the MBMS through the indication information, the MCS can be adjusted flexibly by sending the indication information dynamically; therefore, the drawback that the corresponding MCS of a certain multimedia broadcast multicast service cannot be set and regulated flexibly in the application of the conventional multimedia broadcast multicast technology is overcome.

Description

technical field [0001] The present invention relates to the communication field, in particular to a modulation and coding scheme determination method for multimedia broadcast and multicast services and a multimedia broadcast multicast coordination entity (Multimedia Broadcast Multicast Coordination Entity, MCE). Background technique [0002] In the LTE (Long Term Evolution, Long Term Evolution) system, the Multimedia Broadcast and Multicast Service (MBMS) can adopt a multicast mode, which is called MBSFN (Multicast / Broadcastover Single Frequency Network, Single Frequency Network) Multicast broadcast) transmission mode, MBMS transmitted in multicast mode, also known as MBSFN service, can use the same modulation and coding format in multiple cells, and use the same physical resources to transmit the same content. Features of MBMS multi-cell transmission: 1) synchronous transmission in the MBSFN area; 2) support for multi-cell MBMS transmission combination; 3) MTCH (Multicast T...
