Embodiment 1

[0099] see figure 1 As shown, this embodiment provides a data packet transmission processing flow after the host base station receives the data packet. This processing flow is applicable to both the high-speed mobile scenario and the non-high-speed mobile scenario.

[0100] In this embodiment, the transmission of the data message by the donor base station mainly includes the following process:

[0101] Step 101: The donor base station receives the data message.

[0102] The network transmission of data services is mainly as follows: the data message sent by the user is sent to the RN connected to the sending user, and the RN forwards the data message to the host base station to which the RN belongs after receiving the data message from the user. The host base station sends the data service to the opposite host base station through the external data network, and the opposite host base station sends the data service to the receiving user through the RN on the receiving user sid...

Embodiment 2

[0156] see Figure 4 As shown, this embodiment provides a host base station, the host base station is set between an external data network and at least one relay node, and the host base station mainly includes a data network gateway 401, a relay data gateway 402, and a relay service gateway 403 , a transmission mode determination unit 404 , an analysis unit 405 , and a control unit 406 . The connection relationship and working principle of each part are as follows:

[0157] A data network gateway 401 (Packet Data Network Gateway, PGW for short) is connected to an external data network, where the external data network (Packet Data Network, PDN for short) can be, for example, the Internet, an IP multimedia system (IP Multimedia Subsystem, IMS for short), etc. Network or other mobile communication networks.Data network gateway 401 in the present embodiment and the connection of external data network can be but not limited to be connected by security gateway interface (being call...

Embodiment 3

[0171] see Figure 5 As shown, the main difference between the donor base station provided in this embodiment and the second embodiment is that the donor base station further includes: a storage unit 501 .

[0172] A relational mapping table is pre-stored in the storage unit 501, and the following information is stored in the relational mapping table: the mapping relation of each relay node address and the transmission mode corresponding to each relay node, and each relay node address is unique Each relay node identified.

[0173] The transmission mode determination unit 504 is also connected to the storage unit 501, and the transmission mode determination unit 504 is specifically configured to query the relationship mapping table according to the destination relay node address (or sender relay node address) of the data message, and convert the current data message The transmission mode corresponding to the relay node address is used as the transmission mode of the current da...

Abstract

The invention relates to the communication field and discloses a data transmission method, a host base station and a data network system. The data transmission method comprises steps that: data message is received by the host base station; a transmission mode of the data message is determined by the host base station, the data message is forwarded by the host base station according to a destination address of the data message; user business information of the data message is acquired by the host base station if the transmission mode is a non-transparent mode, corresponding service quality strategy of data message transmission is determined according to the user business information, and the data message is transmitted by the host base station based on the service quality strategy according to the destination address of the data message. Through the technical scheme, transparent transmission and nontransparent transmission of the data message are compatible, so business compatibility processing capability of the host base station is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method, a host base station and a data network system. Background technique [0002] The 3rd Generation Partnership Project (The 3rd Generation Partnership Project, referred to as 3GPP) is the leading 3G technical specification organization. [0003] The 3GPP protocol regulates the relevant scenarios and protocols of fixed relays (Relay) in the communication system. In the 3GPP network, the relay node (Relay Node, RN for short) is a relay device set between the user and the base station (the base station connected to the user through the relay node is also called the host base station). interface connection. [0004] With the RN, the host base station and the user do not communicate directly, but through the RN, the RN forwards the communication signal amplification or regeneration processing to realize the communication interaction between the user and the...
