sending, by the core network node, the first information to the access network node through a core access and mobility management function (AMF).
However, Yu discloses:
wherein the sending, by a core network node ([55:56-57:39] core network element), first information to an access network node ([55:56-57:39] first core network element determines a QoS profile corresponding to the network status information … determines a QoS profile of the access network device based on the network status information … first core network element sends indication information to the access network device … includes a QoS profile that corresponds to the network status information)
It would have been obvious to one of ordinary skill in the pertinent art before the effective filing date of the claimed invention to modify the invention of Han in view of Yu to have obtained information from a core network node that indicates a type or characteristic of the service data, the information being generated by parsing service data, and performed by the access network node transmission processing according to the obtained information comprising delay information of the service data. One of ordinary skill in the art would have been motivated to do so to implement an update procedure of a multi-access PDU session such as to request the first core network element which access technology to use, allocation of a transmission resource, etc. (Yu, [1:48-2:13]).
Han-Yu do not explicitly disclose:
performing, by the core network node according to the first information, mapping on the service data to obtain a quality of service (QoS) flow, and sending, to the access network node, the QoS flow obtained through mapping, wherein the QoS flow carries the first information;
sending, by the core network node, a general packet radio service tunneling protocol of a user plane (GTP-U) message to the access network node, wherein a header of the GTP-U message carries the first information; or
sending, by the core network node, the first information to the access network node through a core access and mobility management function (AMF).
However, Ma discloses:
performing, by the core network node according to the first information ([0120] network element of a core network … UPF, may map the service data flow to a QoS flow, see [0061] mapping relationship between the service data flow and a QoS flow corresponding to the QFI), mapping on the service data to obtain a quality of service (QoS) flow ([0120] network element of a core network … UPF, may map the service data flow to a QoS flow), and sending, to the access network node ([0115] RAN), the QoS flow obtained through mapping ([0115] receiving a downlink QoS flow from the UPF (e.g., the RAN receives from the UPF)), wherein the QoS flow carries the first information ([0061] mapping relationship between the service data flow and a QoS flow corresponding to the QFI [0134] QoS information includes a QoS flow identifier (QFI) and QCIs);
It would have been obvious to one of ordinary skill in the pertinent art before the effective filing date of the claimed invention to modify the invention of Han-Yu in view of Ma to have performed, by the core network node, mapping on the service data to obtain a QoS flow and sent it to an access network node. One of ordinary skill in the art would have been motivated to do so to have a plurality of QCIs performed for a single service data flow and QoS guarantee is performed on data packets in different time slices (Ma, [0008]).
Regarding claim 11, Han-Yu-Ma disclose:
The method according to claim 10, set forth above,
Han-Yu do not explicitly disclose:
wherein the performing, by the core network node according to the first information, mapping on the service data to obtain a QoS flow comprises:
mapping, by the core network node according to a preset mapping rule, the service data to the QoS flow; wherein
the preset mapping rule comprises: mapping service data with a first priority to a target QoS flow, wherein
the target QoS flow is a first QoS flow, or the target QoS flow is a QoS flow corresponding to a first QoS flow indication (QFI).
However, Ma discloses:
wherein the performing, by the core network node according to the first information ([0120] network element of a core network … UPF, may map the service data flow to a QoS flow, see [0061] mapping relationship between the service data flow and a QoS flow corresponding to the QFI), mapping on the service data to obtain a QoS flow ([0120] network element of a core network … UPF, may map the service data flow to a QoS flow) comprises:
mapping, by the core network node according to a preset mapping rule ([0120] network element of a core network … UPF, may map the service data flow to a QoS flow, see [0061] mapping relationship between the service data flow and a QoS flow corresponding to the QFI (i.e. preset rule based on QFI)), the service data to the QoS flow ([0120] network element of a core network … UPF, may map the service data flow to a QoS flow); wherein
the preset mapping rule ([0120] network element of a core network … UPF, may map the service data flow to a QoS flow, see [0061] mapping relationship between the service data flow and a QoS flow corresponding to the QFI (i.e. preset rule based on QFI)) comprises: mapping service data with a first priority to a target QoS flow ([0120] network element of a core network … UPF, may map the service data flow to a QoS flow [0143] data packet that carries the first QCI … configuration parameter corresponding to the first QCI … priority), wherein
the target QoS flow is a first QoS flow, or the target QoS flow is a QoS flow corresponding to a first QoS flow indication (QFI) ([0061] mapping relationship between the service data flow and a QoS flow corresponding to the QFI).
It would have been obvious to one of ordinary skill in the pertinent art before the effective filing date of the claimed invention to modify the invention of Han-Yu in view of Ma to have mapped the service data to the QoS flow based on a preset mapping rule comprising mapping service data with a first priority to a target QoS flow corresponding to a QFI. One of ordinary skill in the art would have been motivated to do so to have a plurality of QCIs performed for a single service data flow and QoS guarantee is performed on data packets in different time slices (Ma, [0008]).
