Embodiment Construction

[0036] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0037] A logical channel identification transmission method in MBMS provided by the present invention, such as figure 1 As shown, it mainly includes the following steps:

[0038] In step 101, an evolved node (eNB, Evolved Node B) indicates to a UE a radio frame or a radio subframe carrying an MCCH through a system broadcast message.

[0039] In the system broadcast message, the eNB sends the location information of the radio frame or the radio subframe carrying the MCCH to the UE.

[0040] Step 102, the UE reads the content of the MAC header according to the radio frame or radio subframe, identifies the logical channel type according to the content of the MAC header, and reads data from the corresponding MAC Service Data Unit (SDU, Service Data Unit).

[0041] Considering a simple application scenario where only tw...

Abstract

The invention discloses a method for transmitting a logical channel identification in multimedia broadcast and multicast service (MBMS). The method comprises the following steps: an evolution node (eNB) indicates a wireless frame or wireless sub-frame carrying a MBMS control channel (MCCH) to user equipment (UE) through a system broadcast message; and the UE reads the content of a media access control (MAC) head from the wireless frame or wireless sub-frame, identifies the logical channel type according to the content of the MAC head, and reads data from a MAC service data unit (SDU). The invention also discloses a logical channel identification transmission system in MBMS. Adoption of the method and the system realizes that the UE can accurately identify the logical channel type under the condition that a plurality of different types of MBMS logical channels are multiplexed on an MAC protocol data unit (PDU).

Description

technical field [0001] The present invention relates to a multimedia broadcast and multicast service (MBMS) control signaling transmission technology in a long-term evolution (LTE) system, in particular to a logical channel identification transmission method and system in MBMS. Background technique [0002] With the rapid development of the Internet (Internet), 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., which not only meet the needs of mobile The ever-increasing business demands of users also bring new business growth points to 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 ord...
