Detailed Description

The present invention will be described in further detail below with reference to the attached drawings, wherein it is apparent that the embodiments described are only some, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Example 1:

fig. 1 is a mapping table generating method according to an embodiment of the present invention, where the method includes the following steps:

s101: determining whether there is a value of a second parameter matching the value of the first parameter corresponding to the 5QI value according to the value of the first parameter corresponding to the 5QI value in the 5G quality of service indicator (5G Quality of Service Indicator,5QI) table and the value of the second parameter corresponding to each quality of service class identity (Quality of Service Class Identifer, QCI) value.

The 5G network is a fifth generation mobile communication network, and its transmission speed can reach tens of Gb per second, which is hundreds of times faster than that of the 4G network. However, in the promotion of the 5G network and in the early application period, the 4G network still exists, so that the 5G network and the 4G network can interoperate for the convenience of the user, and the method has a crucial role, namely that the user can switch from the 5G network to the 4G network or from the 4G network to the 5G network. Because there is no QoS flow in the 4G network, only there is E-RAB, if the interoperability of the 5G network and the 4G network is to be realized, a mapping relationship between QoS flows and E-RAB needs to be established, where a QoS flow and a 5QI value have a correspondence, that is, a QoS flow may be retrieved through the 5QI value and an E-RAB may be retrieved through the QCI value, and therefore, in a specific implementation process, a mapping relationship between the QCI value and the 5QI value is actually established, and after the mapping relationship is established, the mapping relationship may be stored in the 5QI table. In a specific implementation process, a 5QI table and a QCI table are pre-stored in a 5G core network device, where the 5QI table includes a 5QI value and a value of a first parameter corresponding to each 5QI value, where the first parameter includes a resource type, a priority, a packet delay budget and a packet error rate, and the QCI table includes a QCI value and a value of a second parameter corresponding to each QCI value, where the second parameter includes a resource type, a priority, a packet delay budget and a packet error rate.

In the 5G core network device, since the parameters in the QCI table are in the 5QI table, it can be determined whether the first parameter corresponding to the 5QI value matches the second parameter corresponding to the QCI value according to the values of the parameters in the 5QI table and the QCI table.

Specifically, the 5G core network device determines, according to the value of the first parameter corresponding to the 5QI value and the value of the second parameter corresponding to each QCI value in the 5QI table, whether there is a value of the second parameter matching the value of the first parameter corresponding to the 5QI value.

For example, if the value of the first parameter corresponding to the 5QI value and the value of the second parameter corresponding to a certain QCI value in the QCI table are within a preset range, it may be determined that the value of the first parameter corresponding to the 5QI value matches the value of the second parameter corresponding to the QCI value.

S102: and if the target QCI value corresponding to the 5QI value is determined according to the QCI value corresponding to the matched value of the second parameter.

In order to establish a one-to-one mapping relationship between the 5QI value in the 5QI table and the QCI value in the QCI table, since the value of the first parameter and the value of the second parameter that are matched with each other are found according to the value of the first parameter and the value of the second parameter, that is, the QCI value and the 5QI value that are matched with each other are found, the target QCI value corresponding to the 5QI value can be determined according to the value of the matched second parameter.

Specifically, if there is a match between the value of the second parameter corresponding to the QCI value and the value of the first parameter corresponding to the 5QI value in the 5QI table in the QCI table, determining the QCI value corresponding to the 5QI value according to the QCI value corresponding to the matched value of the second parameter. Specifically, the matched QCI value is taken as the target QCI value corresponding to the 5QI value.

S103: and if the target QCI value corresponding to the 5QI value does not exist, determining the target QCI value corresponding to the 5QI value as an invalid value.

If there is no match between the value of the second parameter corresponding to the QCI value and the value of the first parameter corresponding to the 5QI value in the 5QI table in the QCI table, the value of the first parameter corresponding to the 5QI value cannot find the corresponding mapped QCI value in the QCI table, but for convenience of subsequent use, the corresponding target QCI value is set for the 5QI value, so the target QCI value corresponding to the 5QI value is an invalid value, for example, the invalid value may be "NULL", "#", or "×", or other characters. In the implementation process, a column is added in the 5QI table, the attribute corresponding to the column is the target QCI value, and the 5QI table after the column is added is used as a mapping table.

In the embodiment of the invention, the value of the first parameter corresponding to the 5QI value in the 5QI table is matched with the value of the second parameter corresponding to each QCI value, and the target QCI value corresponding to the 5QI value is determined according to the QCI value corresponding to the matched value of the second parameter, so that a mapping table is generated, and the interoperation of the 4G core network equipment and the 5G core network equipment can be realized based on the mapping table.

Example 2:

in order to better generate the mapping table, on the basis of the foregoing embodiment, in an embodiment of the present invention, the first parameter includes: resource type, priority, packet delay budget, and packet error rate.

Wherein the resource types include guaranteed stream bit rates (Guranteed Bit Rate, GBR) and Non-guaranteed stream bit rates (Non Guranteed Bit Rate, non-GBR); each QCI value is associated with a priority, with a priority value of 1 being the highest priority level; the packet delay budget may be, for example, 100ms, and the packet error rate may be, for example, 10 ^-2 Etc.

In order to obtain a more accurate mapping table, in the embodiments of the present invention, when the first parameter includes: when the resource type, the priority, the packet delay budget and the packet error rate are determined, the determining whether the value of the second parameter matched with the value of the first parameter corresponding to the 5QI value includes:

As can be seen from the description of the above embodiments, the first parameters include, in particular, the resource type, the priority, the packet delay budget and the packet error rate. Therefore, when the first parameter includes a resource type, a priority, a packet delay budget, and a packet error rate, the value of the second parameter matching the value of the first parameter corresponding to the 5QI value is determined according to the value of the resource type, the value of the priority, the value of the packet delay budget, and the value of the packet error rate.

Since GBR in a resource type refers to a bit rate of a bearer requirement being "permanently" constantly allocated by the network, the corresponding bit rate can be maintained even in case of network resources being strained. In contrast, non-GBR refers to the requirement that traffic (or bearers) need to withstand reduced rates in the case of network congestion, since Non-GBR bearers do not occupy fixed network resources and can be established for a long time, whereas GBR bearers are typically established only when needed. Therefore, the traffic requirements that the GBR and Non-GBR in the resource type need to implement are completely different, so the value of the resource type must be the same when determining whether the value of the first parameter corresponding to the 5QI value matches the value of the second parameter of the QCI value. And the priority refers to the importance of the service or whether it should be handled in time, so that the value of the priority must be the same when determining whether the value of the first parameter corresponding to the 5QI value matches the value of the second parameter.

Specifically, for any QCI value, the value of the second parameter corresponding to the QCI value is determined, and for any 5QI value, the value of the first parameter corresponding to the 5QI value is also determined, so when determining whether the value of the first parameter corresponding to the 5QI value matches the value of the second parameter, firstly judging whether the value of the priority corresponding to the 5QI value and the value of the resource type are equal, if so, taking the QCI value as a candidate QCI value, and if not, determining that there is no value of the second parameter matching the value of the first parameter corresponding to the 5QI value; if so, it is also necessary to determine whether the packet delay budget and the packet error rate meet the requirements. Specifically, whether the difference between the packet delay budget value corresponding to the 5QI value and the packet delay budget value corresponding to the candidate QCI value is smaller than a first set threshold value or not is judged, and whether the difference between the packet error rate value corresponding to the 5QI value and the packet error rate value corresponding to the candidate QCI value is smaller than a second set threshold value or not is judged; if so, determining that the value of a second parameter matched with the value of the first parameter corresponding to the 5QI value exists; otherwise, it is determined that there is no value of the second parameter that matches the value of the first parameter corresponding to the 5QI value.

For example, the resource type, priority, packet delay budget and packet error rate corresponding to a certain 5QI value in the 5QI table are respectively: GBR,20, 100ms,0.02, the 5QI value is 2, and the resource type, priority, packet delay budget and packet error rate corresponding to a certain QCI value in the QCI table are respectively: GBR,20, 50ms,0.025, the QCI value is 12. The first set threshold value is 20ms, the second set threshold value is 0.001, the value of the corresponding resource type is GBR when the specific 5QI value is 2, the value of the priority is 20, the value of the corresponding resource type is GBR when the QCI value is 12, and the value of the priority is 20 the same, therefore, the QCI value can be used as a candidate QCI value corresponding to the 5QI value, but the difference between the value of the packet delay budget corresponding to the 5QI value is 100ms and the value of the packet delay budget corresponding to the QCI value is 12 is 50ms and is larger than the first set threshold value by 20ms, and the difference between the value of the packet error rate corresponding to the 5QI value is 0.005 and the value of the packet error rate corresponding to the QCI value is 12 and is larger than the second set threshold value by 0.001, so that the 5QI value is not matched with the QCI value.

In order to achieve one-to-one mapping between the 5QI value and the QCI value, in the above embodiments, if there are at least two values of the second parameter of the QCI value that match the value of the first parameter, the determining the target QCI value corresponding to the 5QI value includes:

For one 5QI value, if it is determined that the value of the second parameter having at least two QCI values matches the value of the first parameter corresponding to the 5QI value according to the above matching manner, one of the at least two QCI values may be arbitrarily selected as the target QCI value corresponding to the 5QI value.

Example 3:

fig. 2 is a flow chart of a mapping method of a 5G core network and a 4G core network based on a mapping table generating method according to an embodiment of the present invention, where the method includes the following steps:

s201: and determining a value to be mapped corresponding to the QoS flow or the E-RAB according to the received QoS flow or the E-RAB, wherein the value to be mapped is a 5QI value or a QCI value.

When the QoS flow or the E-RAB is received, a value to be mapped corresponding to the QoS flow or the E-RAB may be determined according to the QoS flow or the E-RAB, where the value to be mapped may be a 5QI value or a QCI value. Specifically, when the received QoS flow is the QoS flow, determining a 5QI value corresponding to the QoS flow according to the QoS flow; when the E-RAB is received, determining the QCI value corresponding to the E-RAB according to the E-RAB.

S202: and determining a mapping value with a mapping relation with the value to be mapped according to the value to be mapped and a stored target mapping table.

Because the first core network device pre-stores the target mapping table, wherein the target mapping table comprises 5QI values and QCI values corresponding to each 5QI value, and the mapping value having a mapping relation with the value to be mapped is determined according to the value to be mapped and the target mapping table.

For example, when the value to be mapped is a 5QI value, searching a QCI value having a mapping relation with the 5QI value from a target mapping table; and when the value to be mapped is the QCI value, searching a 5QI value with a mapping relation with the QCI value from a target mapping table.

S203: and determining E-RAB or QoS flow corresponding to the mapping value, and mapping the QoS flow or E-RAB to the E-RAB or QoS flow.

When the mapping value is determined, according to the mapping value, the E-RAB or QoS flow corresponding to the mapping value can be determined, and the QoS flow or E-RAB can be mapped to the E-RAB or QoS flow.

After defining a one-to-one mapping relation between QCI and corresponding 5QI, when receiving an E-RAB, determining a value to be mapped corresponding to the E-RAB, namely a QCI value, according to the E-RAB, directly indexing to the corresponding 5QI value according to the QCI value, and then determining QoS flow corresponding to the 5QI value according to the 5QI value, so as to map the E-RAB into QoS flow. Similarly, when a QoS flow is received, a value to be mapped, i.e., a 5QI value, corresponding to the QoS flow is determined according to the QoS flow, the corresponding QCI value can be directly indexed to by the 5QI value, and then the corresponding E-RAB is determined according to the QCI value, so that the QoS flow is mapped into the E-RAB.

Example 4:

in order to more accurately determine a mapping value having a mapping relationship with a value to be mapped, in the embodiment of the present invention, if the first core network device is a 4G core network device, before determining the mapping value having the mapping relationship with the value to be mapped according to the value to be mapped and a stored target mapping table, the method further includes:

and storing the first mapping table as a target mapping table.

The key to realizing interoperability between the 5G network and the 4G network is that the mapping table in the core network device carrying the 5G network is the same as the mapping table in the core network device carrying the 4G network.

Specifically, after the 5G core network device generates the first mapping table according to the mapping table generating method described in the foregoing embodiment, the first mapping table is sent to the 4G core network device. The 4G core network device receives the first mapping table and takes the first mapping table as a target mapping table.

On the basis of the above embodiment, in an embodiment of the present invention, the method further includes:

Receiving mapped E-RAB or QoS flow sent by second core network equipment;

The second core network device can determine the QoS flow or E-RAB having a mapping relation with the E-RAB or QoS flow according to the E-RAB or QoS flow and the target mapping table, and send the mapped E-RAB or QoS flow to the first core network device, the first core network device receives the mapped E-RAB or QoS flow, and the first core network device can also determine the mapping relation between the QoS flow and the E-RAB according to the value to be mapped. And judging whether the mapped E-RAB or QoS flow of the first core network equipment is consistent with the mapping relation between the QoS flow and the E-RAB determined by the second core network equipment.

Therefore, in the embodiment of the present invention, if it is determined that the mapping relationship between QoS flows and E-RABs corresponding to the values to be mapped of the first core network device and the second core network device is inconsistent, the method further includes:

In order to realize synchronization of the mapping relationship between the QoS flow and the E-RAB, when the mapping relationship between the first core network device and the second core network device is inconsistent, priorities of the first core network device and the second core network device may be preset, and then the QoS flow with inconsistent mapping relationship and the E-RAB are synchronized according to the priorities of the first core network device and the second core network device. Specifically, if the mapping relationship determined by the first core network device is inconsistent with the mapping relationship determined by the second core network device, taking the mapping relationship between the QoS flow and the E-RAB corresponding to the mapping value stored by the core network device with the highest priority as the mapping relationship after synchronization according to the priorities of the first core network device and the second core network device.

When the two mapping relations are inconsistent, the priority of each core network device is preset in order to synchronize the mapping relation of the first core network device and the second core network device. Specifically, the mapping relationship may be sent to the peer end with information of a priority corresponding to the core network device, for example, when the 5G core network device sends the mapping relationship corresponding to the mapping value to the 4G core network device, the information of the priority corresponding to the 5G core network device and the mapping relationship are sent to the 4G core network device together, or when the 4G core network device sends the mapping relationship corresponding to the mapping value to the 5G core network device, the information of the priority corresponding to the 4G core network device and the mapping relationship are sent to the 5G core network device together. In the implementation process, the priority corresponding to the 5G core network device may be set to be the highest.

In the embodiment of the present invention, if the mapping value is a 5QI value, and at least one mapping value having a mapping relationship with the value to be mapped is determined, the mapping the QoS flow or E-RAB to the E-RAB or QoS flow includes:

Specifically, when the mapping value is a 5QI value and at least one mapping value having a mapping relationship with a value to be mapped exists in the target mapping table, one mapping value may be selected from the at least one mapping values as a target mapping value, specifically, any one mapping value may be selected as a target mapping value, and the E-RAB is mapped to a QoS flow corresponding to the target mapping value; the target QoS flow may also be pre-specified and the E-RAB mapped into the target QoS flow.

Specifically, a mapping relationship exists between one 5QI value and one QCI value in the mapping table, and a mapping relationship exists between one QCI value and at least one 5QI value, that is, only one QCI value can be determined according to one 5QI value, and multiple 5QI values can be determined according to one QCI value. Therefore, when the QCI value is received, a plurality of mapping values, namely a plurality of 5QI values, can be determined according to the QCI value, if a plurality of mapping values exist, a plurality of corresponding QoS flows exist, and at the moment, one mapping value can be selected as a target mapping value to map the E-RAB into the QoS flow corresponding to the target mapping value; the E-RAB may also be mapped to a target QoS flow that is set in advance.

In the embodiment of the present invention, if the mapping value is a QCI value, before determining the QoS flow corresponding to the mapping value, the method further includes:

In the target mapping table, the QCI value may be a valid value or an invalid value, where the QCI value being an invalid value represents the E-RAB corresponding to the QCI not supporting the mutual mapping with QoS flows. Therefore, when the mapping value is a QCI value, it should also be determined whether the QCI value is valid, if so, the QoS flow corresponding to the QCI value is determined, and if not, the QCI value has no corresponding QoS flow.

When the QoS flow to be mapped exists, the corresponding QCI value of the QoS flow is filled in through the target mapping table. The QCI value may be a valid value or an invalid value. Wherein a QCI value of invalid value represents a mutual mapping between the QoS flow unsupported and the E-RAB. In the implementation process, the target mapping table may be stored in the 5G core network device.

When an E-RAB is established, the QCI value corresponding to the E-RAB is used for searching the 5QI value corresponding to the QCI value in the target mapping table, so that the E-RAB can be mapped to the QoS flow corresponding to the 5QI value. In the implementation process, the target mapping table may be stored in the 4G core network device.

When QoS flow and E-RAB are needed to be mapped mutually, if QoS flow is received, a 5QI value corresponding to the QoS flow is determined, a QCI value is determined according to the 5QI value, and a corresponding E-RAB is determined according to the QCI value, so that the QoS flow is mapped to the E-RAB. If the E-RAB is received, determining a QCI value corresponding to the E-RAB, determining a 5QI value according to the QCI value, and determining a corresponding QoS flow according to the 5QI value, so as to map the E-RAB to the QoS flow. Based on the above embodiment of the present invention, in the embodiment of the present invention, the mapping relationship is pre-established and stored in the mapping table, specifically, when the mapping relationship is established, the mapping relationship between each QoS profile and the E-RAB is defined based on the 5QI table, for example, when a handover request is received, for example, the request includes a 5QI value, a corresponding QCI value is found according to the 5QI value, and a corresponding E-RAB can be found according to the QCI value.

The table 1 is shown as a 5QI table, wherein the first column is 5QI value, the value range of 5QI value is 0-127, the second column is resource type including GBR and non-GBR, the third column is priority, the fourth column is packet delay budget, the fifth column is packet error rate, and the sixth column is exemplary service.

TABLE 1

Establishing a mapping relation between 5QI and QCI:

according to the value or index requirement of the QoS parameter defined by the QCI of 4G, searching the value or index requirement of all QoS parameters in a 5QI table, searching the 5QI closest to the value or index requirement of the QoS parameter defined by the QCI, and then establishing a one-to-one mapping relation between the QCI and the 5 QI.

If the QoS parameters or indexes defined in the 5QI table do not meet the requirements, the setting personnel can redefine a new 5QI value, and the values of the various columns of parameters are the values of the QoS parameters defined by the QCI or the index requirements, and when the values of the parameters required in the 5QI are not in the QCI, the values of the parameters in the 5QI can be the default values of the system. In addition, the mapping relation is set to an invalid value of 5QI which does not correspond to any E-RAB, for example, the invalid value may be NULL, special characters, or the like.

The mapping relationship between QCI and 5QI may be defined by a target mapping table. In the current 5QI table, a column is added at the last of the table, and the value corresponding to the column is the QCI value corresponding to the 5QI value. If the 5QI value does not correspond to any QCI value, the value of this term is an invalid value.

For example, fig. 3 is a flow chart of a 5G core network device and a method for generating a mapping table and mapping table of a 4G core network, where 5G CN refers to a virtualized 5G network structure and is used to represent the 5G core network device, and 4G CN refers to a virtualized 4G network structure and is used to represent the 4G core network device.

The process of map generation and interoperation is set forth in detail below:

1. determining whether the value of the second parameter matched with the value of the first parameter corresponding to the 5QI value exists according to the value of the first parameter corresponding to the 5QI value in the 5QI table and the value of the second parameter corresponding to each QCI value; if the target QCI value exists, determining the target QCI value corresponding to the 5QI value according to the QCI value corresponding to the matched value of the second parameter; and if the target QCI value does not exist, determining that the target QCI value corresponding to the 5QI value is an invalid value, and thus determining a target mapping table.

2. And determining a value to be mapped corresponding to the QoS flow or the E-RAB according to the received QoS flow or the E-RAB, wherein the value to be mapped is a 5QI value or a QCI value.

3. And determining a mapping value with a mapping relation with the value to be mapped according to the value to be mapped and a stored target mapping table.

4. E-RAB or QoS flow corresponding to the mapping value is determined, and QoS flow or E-RAB is mapped to E-RAB or QoS flow.
