Embodiment 1

[0048] Embodiment 1 provides a multimedia packet data transmission method, such as figure 1 As shown, the method includes:

[0049] Step S101: Determine to reconstruct the downlink packet data according to the current wireless link condition;

[0050] Step S102: reconstructing the downlink packet data;

[0051] Step S103: Send the reconstructed downlink packet data to the UE.

[0052] The method provided in this embodiment corresponds to the transmission of downlink packet data in practical applications.

[0053] In this embodiment, before sending the packet data to the user, the network side entity, such as the base station, first determines to reconstruct the packet data according to the wireless link conditions, so that the data to be transmitted on the link is suitable for the current wireless link Therefore, the process of sending packet data from the base station to the user in this embodiment can be quickly adapted to the situation of the wireless link.

[0054] In th...

Embodiment 2

[0056] In the method provided in the second embodiment, the reconstruction of packet data is completed by the base station itself. In this embodiment, the gateway includes S-GW and PDN-GW as an example, such as figure 2 As shown, the multimedia packet data transmission method provided in this embodiment includes the following steps:

[0057] Step S201: the downlink packet data is sent by the PDN-GW 204 to the S-GW 203;

[0058] Specifically, the downlink packet data can be transmitted from the PDN-GW 204 to the S-GW 203 through the tunneling technology.

[0059] Step S202: the downlink packet data is sent by the S-GW 203 to the base station 202;

[0060] Specifically, the downlink packet data can be transmitted from the S-GW 203 to the base station 202 through another tunnel.

[0061] Step S203: The base station 202 judges whether packet data reconstruction is needed according to the current wireless link condition; if yes, execute step S204; if not, execute step S205;

Embodiment 3

[0070] The third embodiment provides a multimedia packet data transmission method, in which the reconstruction of the packet data is completed by the gateway, and the packet data transmission process is still a downlink process. In this embodiment, the gateway includes the S-GW and the PDN-GW, and the task subject to complete packet data reconstruction may be the S-GW or the PDN-GW. like image 3 As shown, the method provided in this embodiment includes the following steps:

[0071] Step S301: The base station 302 judges whether to perform packet data reconstruction according to the current wireless link conditions;

[0072] Step S302: The base station 302 sends a request message requesting the S-GW or PDN-GW 304 to enable or disable the data reconstruction function through the MME 303 to the S-GW or PDN-GW 304 according to the judgment result in step S301;

[0073] In addition, the base station 302 may also notify the S-GW or PDN-GW 304 of the degree of data reconstruction ...

Abstract

The embodiment of the invention provides a multi-media packet data transmission and processing method and corresponding network equipment, wherein the multi-media packet data transmission method comprises the following steps that: a base station determines to reconstruct downlink packet data according to the situations of a current wireless link; reconstructing the downlink packet data; and the base station sends the reconstructed downlink packet data to a UE. The method provided by the embodiment flexibly reconstructs the packet data according to the actual situations of the wireless link so as to adapt to the fast changes to the wireless link, can overcome the problem of the prior art that the data cannot be quickly adjusted according to the situations of the resources of the wireless link, and is beneficial to providing guarantee for QoS.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for transmitting and processing multimedia packet data and network equipment. Background technique [0002] At present, various manufacturers are actively researching LTE (Long Term Evolved, long-term evolution network) / SAE (System Architecture Evolved, system architecture evolution network). The purpose of LTE is to provide a network that can reduce delay, increase user data rate, and improve system capacity and coverage. A low-cost network, the network uses PS (Packet Service, Data Packet Service) domain services, and the bearer network is IP (Internet Protocol, Internet Protocol) bearer. [0003] In the prior art, when transmitting voice coded frames of VoIP (Voice over Internet Protocol, voice over packet protocol) data, the user plane information must be encapsulated by the RTP (Real-time Transport Protocol, Real-time Transport Protocol) protocol, and the RTP...
