Detailed Description
Features and exemplary embodiments of various aspects of the present invention will be described in detail below, and in order to make objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
In the initial stage of 5G construction, many operators will choose NSA architecture networking to implement 5G application as soon as possible, especially using 4G core mesh to support option3/3a/3x of 5G base station. Under the NSA architecture of Option3/3a/3x, the RAT Type of 5G users still shares the 4G E-UTRAN with 4G users. At this time, there is no effective method if a PCC policy different from 4G is issued for a user in a 5G access situation.
In fact, when the user's data plane is transferred by the 5G base station gNB, it is known from the MME to the Serving GateWay (SGW) or PDN GateWay (PGW) or serving-public data GateWay SAE-GW. Taking option3x as an example, as is clear from the 3GPP 23.401 protocol, when the user data plane is migrated from the 4g base station eNB to the 5g base station gNB, the eNB indicates to the MME that an Evolved Radio Access Bearer (E-RAB) modification is initiated by the eNB to indicate that a Secondary Radio Access Type usage report (Secondary Radio Access RAT usesmagereport) field is included in the E-RABModification Indication message, and a Secondary Radio Access Type identifier (Secondary Radio Access Type — NR) in the field indicates that the user data plane is to be migrated to the gNB. After receiving the message, the MME then sends a Modify Bearer Request modification Bearer Request message to the SGW/PGW/SAEGW, which also carries the field information.
However, the protocol 23.401 does not indicate, and after receiving the important information, the PGW/sae gw may then transmit the important information to the PCRF unit. Looking at the 3GPP latest R15 version 29.212 specification of the PCC protocol between the PGW/sae gw and the PCRF unit, no field related to the important information in the CCR message field sent by the PGW/sae gw to the PCRF unit is seen, i.e. no field containing Secondary RAT Type NR is found.
As indicated by the fields contained in the CCR message in the R15 version 29.212 specification below, where the fields associated with the access type do not indicate the fields associated with the second access type in an NSA network.
