AI Technical Summary

Problems solved by technology

However, the introduction of this technology also brings new problems: that is, the signals from different base stations are regarded as multi-path by the UE, which requires that the data of each path must be sent synchronously; in the chip combination mode, the UE simultaneously receives signals from different base stations. The transmitted service signals are combined at the chip level through the multi-cell joint detection technology, which also requires that the MBMS service signals received by the UE from different cells are the same in the same time slot
Different RLC serial numbers will lead to different wireless signals related to services at the same time, thus making the wireless signals between RNCs asynchronous

Embodiment Construction

[0018] The method and system for synchronizing RLC sequence numbers among RNCs in MBMS system services of the present invention will be described in detail below in conjunction with corresponding drawings and specific embodiments.

[0019] Fig. 1 is a flowchart of a method for synchronizing radio link control sequence numbers between radio network controllers in MBMS system services according to an embodiment of the present invention. As shown in Fig. 1, in step S102, the information source is Obtain the mapping relationship between the length of the preset service data packet and the number of fragments corresponding to the radio link control layer of the radio network controller in command mode, and reserve the radio link control sequence number space for each service flow. Wherein, the length of the preset service data packet refers to the total length that needs to be sent to the UE according to the definition of the MBMS protocol.

[0020] In step S104, the information so...

Abstract

A method for realizing synchronization of RLC sequence number between radio network controllers includes obtaining the mapping relation of preset service data packet length to radio link control sub-plate number by signal source and holding space of control sequence number, confirming said control sub-plate number required by actual service data packet and distributing control sequence number for actual service data packet, fetching out initial radio link control sequence number labeled in actual service data packet and distributing said control sequence number to all said control sub-plates in actual service data packet according to preset sequence.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a system for realizing the synchronization of radio link control serial numbers among radio network controllers. Background technique [0002] With the rapid development of the Internet, people's demand for mobile communication is no longer satisfied with telephone and message services. Therefore, a large number of multimedia services have emerged. In 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, interactive games and so on. MBMS (MultimediaBroadcast / Multicast Service, Multimedia Broadcast Multicast) technology is proposed to realize the most effective use of mobile network resources. It refers to a point-to-multipoint service in which one data source sends data to multiple users, which can realize network resources Sharing, including mobile core...
