Problems solved by technology

A partially distributed solution is formed), if the handover occurs between BSs under two different ASN GWs, since the ASN GW of Profile C only serves as the HO Relay during the handover process, for the passed HO signaling messages, and Relevant information is not saved, so the ASN GW where the target BS is located (i.e., the target ASN GW) does not have the service flow QoS parameter information of the mobile terminal that is about to be handed over, and there is no interaction of this information during the pre-registration of the data channel, then the Failed to register data channel
[0024] When there is an R8 interface between the target BS and the serving BS, and the handover occurs at BSs under two different ASN GWs, since the handover signaling does not pass through the ASN GW, the target ASN GW will not have the QoS parameter information of the mobile terminal service flow , and there is no interaction of this information when the data channel is pre-registered, then the data channel cannot be registered
[0025] Furthermore, the inventor found that if the pre-registration process of the data channel is not performed in the pre-handover preparation phase, but the registration of the data channel is performed in the execution phase, there is also a case where the target BS does not carry the mobile terminal when it initiates the registration of the data channel to the target ASN GW The problem of the QoS parameter information of the service flow, in the above two cases, the data channel cannot be registered

Embodiment approach 1

[0048] refer to image 3 , is a method for assisting data channel registration in an embodiment of the present invention. During the handover process of the mobile terminal (MS) from the serving ASN GW to the target access service network gateway (Target ASN GW), the mobile terminal (MS) is switched by the serving ASN GW ) to the target access service network gateway (Target ASN GW), the target BS performs data channel pre-registration in the handover pre-preparation stage, and the QoS parameter information is carried in the DPPre_Reg Req sent by the target BS or sent by the Anchor ASN GW The DPPre_Reg Rsp message carries QoS parameter information, and the target access service network gateway obtains the QoS parameter information from the DPPre_Reg Req or DP Pre_Reg Rsp message, and the method includes steps:

[0049] Step 301: MS sends MOB_MSHO_REQ message to serving BS.

[0050] Wherein, the BS that provides access service to the MS is called the serving BS (Serving BS) o...

Embodiment approach 2

[0073] refer to Figure 4 , is a method for assisting data channel registration in an embodiment of the present invention. During the handover process of the mobile terminal (MS) from the serving access service network gateway (Serving ASN GW) to the target access service network gateway (Target ASN GW), the target BS performs data channel registration during the handover execution stage, and the target BS registers the data channel in its The sent DP Reg Req carries the QoS parameter information or the DP Reg Rsp message sent by the Anchor ASN GW carries the QoS parameter information, and the target access service network gateway obtains the QoS parameter from the DP Reg Req or DP Reg Rsp message information, the method includes the steps of:

[0074] Step 401: MS sends MOB_MSHO_REQ message to serving BS.

[0075] Wherein, the BS that provides access service to the MS is called the serving BS (Serving BS) of the MS.

[0076] Step 402: After receiving the MOB_MSHO_REQ messa...

Embodiment approach 3

[0099] refer to Figure 5 , is a method for assisting data channel registration in an embodiment of the present invention. During the handover process of the mobile terminal (MS) from the serving access service network gateway (Serving ASN GW) to the target access service network gateway (Target ASN GW), after the Target ASN GW receives the data channel pre-registration request, it does not In the case of the QoS parameter information of the service flow of the mobile terminal, actively request to obtain the relevant equipment or functional entity that stores the QoS parameter information of the service flow of the mobile terminal. The following takes an active request to the target BS as an example for illustration, and the method includes steps:

[0100] Step 501: MS sends MOB_MSHO_REQ message to serving BS.

[0101] Wherein, the BS that provides access service to the MS is called the serving BS (Serving BS) of the MS.

[0102] Step 502: After receiving the MOB_MSHO_REQ m...

Abstract

The embodiment of the invention discloses a method for assisting data channel registration in the switching process, which comprises that: in the process that a mobile terminal switches from a service access service network gateway to a target access service network gateway, the target access service network gateway acquires Q o S parameter information of a service flow of the mobile terminal, and the Q o S parameter information is used for assisting the target access service network gateway in registering data channels. The embodiment of the invention also discloses a target access service network gateway and a device for assisting the data channel registration. The method and the device can make a target ASN GW acquire the Q o S parameter information of the service flow of the mobile terminal, and the parameters can be used for assisting the data channel registration in the switching process.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for assisting data channel registration during handover. Background technique [0002] WiMAX (Worldwide Interoperability for Microwave Access) technology is an air interface standard proposed based on the series of broadband wireless standards of IEEE 802.16. The air interface standards successively released by the IEEE 802.16 working group include 802.16, 802.16a, 802.16d, and 802.16e. The wireless side of the current WiMAX network is mainly based on the IEEE 802.16d / e standard; the 802.16d standard (IEEE 802.16-2004) was formulated in July 2004. The 802.16d standard is the integration and revision of the 802.16 and 802.16a standards. 802.16e standard adds some new functions on the basis of 802.16d standard to support user mobility sex. [0003] figure 1 It is a reference model of WiMAX network architecture, which mainly includes th...
