Embodiment 1

[0097] An embodiment of the present invention provides a data transmission method, which can be applied to an NHN network and used to support switching between different NHN networks.

[0098] For example, the application scenario of the data transmission method provided by the embodiment of the present invention may be: the user equipment moves from a base station coverage area of ​​one NHN network to a base station coverage area of ​​another NHN network during a call.

[0099]For example, the application scenario of the data transmission method provided by the embodiment of the present invention may also be: the area where the user equipment is located is simultaneously covered by base stations of two or more different NHN networks, and during a call, the communication channel of the currently used NHN network Due to the degradation of call quality caused by external interference, it is necessary to transfer communication data to idle communication channels of different NHN n...

example 1

[0126] In this example, interfaces between MMEs of different NHN networks are used as control plane interfaces and user plane interfaces, wherein the control plane interface is S10-N-C, and the user plane interface is S10-N-U.

[0127] The control plane interface S10-N-C establishes a GTP (GPRS Tunneling Protocol, GPRS Tunneling Protocol)-C tunnel between MMEs, and transmits control signaling between MMEs of different NHN networks, such as obtaining mobility management information signaling, establishing data indirect transmission tunnel signaling, etc. Order and so on.

[0128] A data indirect transmission tunnel is established on the data plane interface S10-N-U, and the data in the source network is forwarded to the target network. At the same time, the S11-U interface between the MME and the GW is used to establish a user plane tunnel to transmit data.

[0129] Before the source network data is forwarded to the target network, a user plane tunnel needs to be established b...

example 2

[0147] In this example, interfaces between MMEs of different NHN networks are used as control plane interfaces and user plane interfaces, wherein the control plane interface is S10-N-C, and the user plane interface is S10-N-U.

[0148] The control plane interface S10-N-C establishes a GTP-C tunnel between MMEs, and transmits control signaling between MMEs in the network, such as signaling for acquiring mobility management information and establishing a tunnel for indirect data transmission.

[0149] A data indirect transmission tunnel is established on the data plane interface S10-N-U, and the data in the source network is forwarded to the target network. At the same time, use the S1-U interface between the MME and the AP to establish a user plane tunnel to transmit data.

[0150] Before the source network data is forwarded to the target network, a user plane tunnel needs to be established between the two networks for data forwarding. To establish a user plane tunnel, the sou...

Abstract

Embodiments of the invention provide a data transmission method and network devices. According to the method, a first port identifier corresponding to a data receiving network device is sent to a first network device through a second network device, the data sending network device acquires the first port identifier from the first network device and stores the first port identifier, in a first network, a first access point transmits data to the data sending network device, the data sending network device sends the data to the data receiving network device according to the first port identifier,in a second network, the data receiving network device transmits data to a second access point, so as to enable the second access point to send the data to user equipment. Switch between different NHN networks is realized, data continuity during inter-network switch is ensured in the NHN network, the UE is not authenticated again, the network signaling load is lowered, the network overhead is lowered, the network performance is improved, and a problem in the prior art that switch between different NHN networks is not supported is solved.

Description

【Technical field】 [0001] The solution relates to the technical field of communication, in particular to a data transmission method and network equipment. 【Background technique】 [0002] MulteFire is a new wireless access technology based on LTE (Long Term Evolution, Long Term Evolution), which can operate independently in unlicensed spectrum without the use of licensed frequency band carriers. MulteFire extends LTE to the unlicensed spectrum, and introduces the LBT (Listen Before Tal) mechanism at the physical layer to achieve fair competition for air interface resources with unlicensed band devices. MulteFire can be used in the existing 3GPP (3rd Generation Partnership Project) network architecture and interface with the existing 3GPP core network to provide traditional mobile network operators with capacity, coverage and data offload brought by unlicensed spectrum. [0003] At the same time, MulteFire also introduces a new network architecture, providing a unified plannin...
