Problems solved by technology

The introduction of this technology brings new problems: since the signals from different base stations are regarded as multi-path by the UE, it is required that the data of each path must be sent synchronously
[0009] In the existing protocol, no mechanism is provided to ensure the requirements of the above two aspects, which leads to the impossibility of sending the same MBMS service synchronously between cells belonging to different RNCs

Embodiment Construction

[0029] The main idea of ​​the present invention is that the upper layer network element performs radio link control layer RLC protocol processing on the MBMS service data packet, and sends the radio link control layer protocol data unit RLC PDU obtained after processing to one or more lower layer network elements, The network message carrying the RLC PDU carries time stamp information; after receiving the network message, the lower network element determines, according to the time stamp information carried in the network message, when the MBMS service data carried by the RLC PDU is sent on the wireless interface start time.

[0030] Specifically, the synchronization method described in this embodiment is as follows figure 1 shown, including the following steps:

[0031] Step 110, the upper-layer network element and the lower-layer network element maintain consistent configuration and time synchronization through configuration or control plane signaling process;

[0032] The up...

Abstract

The invention claims a method for synchronously sending same MBMS service data by a wireless network controller, which can send same MBMS service data among subdistricts of different lower-layer network elements. The method comprises the following steps of carrying out radio link control layer RLC protocol processing to an MBMS service data packet by an upper layer network element, sending the radio link control layer protocol data unit RLC PDU obtained after processing to one or more lower layer network elements, carrying time-stamp information in the network message loaded with the RLC PDU; after receiving the network message, determining the starting time for sending the MBMS service data loaded by the RLC PDU at a radio interface according to the carried time-stamp information therein by the lower layer network elements. The method solves the problem of synchronously sending same MBMS service data, improves receiving gain of the MBMS service data by the terminal and avoids same frequency interference of the MBMS service signals among the subdistricts of different lower layer network elements.

Description

technical field [0001] The invention relates to mobile communication value-added services, in particular to a method for multiple wireless network controllers to send MBMS service data. Background technique [0002] Now people's demand for mobile communication is no longer satisfied with telephone and message services. With the rapid development of the Internet, a large number of multimedia services have emerged. For some of these application services, multiple users can receive the same data at the same time, such as video on demand, TV broadcasting, video conferencing, online education, and interactive games. MBMS (Multimedia Broadcast / Multicast Service, multimedia broadcast / multicast service, also known as multimedia broadcast / multicast service) technology is proposed to realize the most effective use of mobile network resources. It refers to a data source that sends data to multiple users. Point-to-multipoint services to realize network resource sharing, including mobil...
