Problems solved by technology

[0006] In the above method, for a certain data flow, it is either transmitted in the LTE network or in the WLAN network, and the offloading is not flexible enough; in addition, since a certain data flow can only be transmitted in a certain network, if the data flow If packet loss occurs in the flow, there will be no recovery mechanism, so the quality of service cannot be guaranteed

Embodiment 1

[0080] Embodiment 1, UE authentication method 1 in WLAN:

[0081] In the embodiment of the present invention, the authentication of the UE in the WLAN mainly has the following two purposes:

[0082] 1. Identify user identity and prevent illegal user access;

[0083] 2. After the identity of the user is identified, the link of the same user in the WLAN can be associated with the link in the LTE.

[0084] Wherein, the authentication method of the UE in the WLAN given in Embodiment 1 is described as follows:

[0085] 1) If the network side (such as eNB) considers that authentication is required, it can initiate an authentication command (Authentication Command) to the UE to trigger the authentication process of the UE;

[0086] 2) The UE initiates an authentication request (AuthenticationRequest) to the network side (such as eNB) in the WLAN, wherein the authentication request carries the C-RNTI and Cell ID of the UE to identify its identity;

[0087]3) After receiving the abo...

Embodiment 2

[0094] Embodiment 2, UE authentication method 2 in WLAN:

[0095] In the second embodiment, the authentication method of the UE in the WLAN may adopt the existing 802.1x authentication method in the WLAN, wherein the authentication method is based on EAP-AKA. The second embodiment will not be described in detail here.

[0096] Since the authentication method of the UE in the LTE network is similar to the authentication method of the UE in the WLAN in Embodiment 2 and is independent of each other, after the WLAN link and the LTE link are established between the UE and the network side, You can associate WLAN links with LTE links in the following ways:

[0097] 1) Determine a unified user ID, which can be used to identify a user in both WLAN and LTE, such as the user's IMSI.

[0098] 2), the authentication process of UE in WLAN is a process independent of LTE authentication, but after the authentication is passed and the WLAN link is established, the user ID needs to be stored...

Embodiment 3

[0104] Embodiment 3, UE authentication method 3 in WLAN:

[0105] In the third embodiment, under the condition that the WLAN module and the LTE module of the UE are inseparable, the authentication process of the LTE is used to realize the authentication of the UE in the WLAN. The specific method is as follows:

[0106] 1), UE reports whether it supports WLAN in LTE, and the WLAN MAC Address; wherein, these WLAN information can be sent to the network side (such as eNB) through the Radio Capabilities procedure, or sent to the network side through any other feasible LTE Procedure ( such as eNB);

[0107] 2) When the UE establishes an LTE link, the network side (such as eNB) can obtain the WLAN capability supported by the UE and the WLAN MAC Address through LTE, and then scan the existing WLAN link according to the WLAN MAC Address. If found, the WLAN The link is associated with the LTE link, so as to start the scheduling strategy negotiation and data flow offloading process;

Abstract

The embodiment of the invention relates to the field of communication technology and discloses a data flow transmission method and a related equipment and a system, wherein the data flow transmission method comprises the following steps: a first network link and a second network link are established between a network side and user equipment; the first network is different from the second network; the user equipment associates the first network link to the second network link; and according to a scheduling algorithm, the user equipment distributes the same data flow into the first network link and the second network link for transmitting. The embodiment of the invention can realize mixed transmission with the same data flow in different networks. Compared with the existing schemes, the embodiment of the invention can carry out distributary more flexibly and improve the service quality.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data stream transmission method and related equipment and systems. Background technique [0002] In order to improve the throughput rate of the air interface, the current 3rd Generation Partnership Project (The 3rd Generation Partnership Project, 3GPP) technology proposes a wireless local area network (Wireless Local Area Networks, WLAN) and Long Term Evolution (Long Term Evolution, LTE ) method for mixed transmission of data streams in the network. Among them, the implementation of this method can refer to figure 1 In the system shown, the specific process is as follows: [0003] First, construct LTE network and WLAN network respectively. Among them, it mainly includes base station (eNB), serving gateway (Serving Gateway, SGW), access point (Access Point, AP), access controller (Access Controller, AC), WLAN access gateway (WLAN Access Gateway, WAG ), Packet Data Gat...
