Description

Method and device for optimizing inter-communication of XN links of different manufacturers

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for optimizing inter-working between XN links of different manufacturers.

Background

In the process of rapid development of the 5G network, operators face rapid deployment of the 5G network, frequency bands of the 5G network are few, 5G frequency bands of different operators are very limited, 5G early-stage users are few, and large-scale network establishment cost of the operators can be gained in a long time.

One of the operator a and the operator B is a contractor and the other is a sharer, and generally, an operator who constructs and opens a network is considered as the contractor and an operator who directly uses the shared network is considered as the sharer.

Specifically, reference may be made to fig. 1 (a) and fig. 1 (b), where fig. 1 (a) is a schematic diagram of a shared scenario created by a 5G network NSA (non-independent networking) together, and fig. 1 (b) is a schematic diagram of a shared scenario created by a 5G network SA (independent networking) together.

For the co-construction sharing scenario, if the sharing party also plans the IP address, the wireless base station side configures two IP addresses, and for the XN link between the wireless base stations, one IP address may be used, or two IP addresses may be used for connection, so there are 3 scenarios when the co-construction sharing base station XN port is networked, see fig. 2, and fig. 2 is a scenario diagram of the co-construction sharing base station XN port networking, as shown in fig. 2, the three scenarios include:

the single IP base station and the single IP base station are communicated, and the construction party and the sharing party share one XN link;

the double IP base stations are communicated with each other, and a construction party and a sharing party are respectively configured with an XN link;

the dual-IP base station and the single-IP base station are communicated, the construction party and the sharing party of the dual-IP base station are respectively configured with an XN link, and the construction party and the sharing party of the single-IP base station share one XN link.

In the three scenes, two intercommunicated base stations are different manufacturer base stations, and the IP configured at the side of the single IP base station is the IP of the construction party.

For the first two scenarios of the three scenarios, the compatibility problem is not generated because the IP strategies used by different manufacturers are the same. For the scene of intercommunication between a double-IP base station and a single-IP base station, some compatibility problems exist at present due to the difference of implementation modes of different manufacturers.

Among the most important compatibility issues are:

the method for automatically adding the external adjacent cells by the dual-XN IP manufacturer is that the external adjacent cells are added according to Broadcast PLMNs (Broadcast public land mobile network fields) of the Served Cell Information NR (serving Cell Information unit), and the Broadcast PLMNs of the Served Cell Information NR carried in XN establishing request, XN establishing response and XN configuration updating messages of the single-XN IP manufacturer at an XN port are the same and are the PLMN of a construction party, so that the dual-XN IP manufacturer at the opposite end can only automatically add the external adjacent Cell Information of the construction party Cell, and if the external adjacent Cell Information of the sharing party Cell needs to be added, the external adjacent Cell Information needs to be manually added by a technician.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the description herein are intended to be within the scope of the present disclosure.

In order to solve the technical problem that in a scene of intercommunication between a dual-IP base station and a single-IP base station of a different manufacturer, the dual-IP base station can only automatically add external adjacent cell information of a building party cell and cannot automatically add external adjacent cell information of a sharing party cell, so that the external adjacent cell information of the sharing party cell can only be manually configured, the embodiment of the application provides an optimization method and device for intercommunication between XN links of the different manufacturer.

For ease of understanding, a brief description of the application scenario of the present application is provided.

For a co-construction sharing scene, the compatibility problem exists when the dual-IP base station and the single-IP base station of different manufacturers are communicated, and the method specifically comprises the following steps: the method for automatically adding the external adjacent cells by the dual XN IP manufacturers is that the external adjacent cells are added according to Broadcast PLMNs of the Served Cell Information NR, and Broadcast PLMNs of the Served Cell Information NR carried by the single XN IP manufacturers in the messages of XN establishment request, XN establishment response, XN configuration update and the like of the XN ports are all the same and are the PLMN of the establishing party, so that the dual XN IP manufacturers at the opposite end can only automatically add the external adjacent Cell Information of the establishing party Cell and cannot automatically add the external adjacent Cell Information of the sharing party Cell.

Therefore, if the external neighbor information to be added is the external neighbor information of the sharing party cell, a technician is required to manually add the external neighbor information.

And because of the definition in the protocol, when the dual XN IP base station receives the XN configuration update message of the peer base station, which carries the cell deletion message (which is triggered when the peer cell is deactivated), the dual XN IP base station automatically deletes the external neighboring cell information of the added cell. That is, even if the technician manually adds the neighbor cell information of the sharing party cell, the neighbor cell is deleted when the cell is deactivated. Due to the manual adding mode of technicians, the external neighbor cell information can not be added again in time, so that the cells can not be switched normally, and the communication quality of users in the switching zone is influenced.

The external neighboring cell information includes, but is not limited to, the PLMN code of the serving cell: the number of significant digits of the global ID of the base station, the global ID of the neighboring base station, the ID of the neighboring Cell, the PCI (Physical Cell Identifier) of the neighboring Cell, the tracking area, and the like.

In order to solve the above technical problem, the present application provides an optimization method for inter-working between different vendor XN links, which is applied to a dual XN IP base station, referring to fig. 3, where fig. 3 is a schematic flow diagram of the optimization method for inter-working between different vendor XN links provided in this embodiment of the present application, and as shown in fig. 3, the method includes the following steps:

s301: and receiving an XN interface message sent by the different manufacturer base station.

In the embodiment of the present application, after receiving the XN interface message, the dual XN IP base station first determines whether the XN interface message is from the different-vendor base station, and if the XN interface message is from the different-vendor base station, the dual XN IP base station needs to perform subsequent steps to determine whether the dual XN IP base station belongs to the incompatible scenario.

If the XN interface message does not come from a base station of a different manufacturer, the problem of incompatibility can not occur, and the existing implementation mode is adopted.

Wherein the XN interface message includes but is not limited to the following messages:

XN SETUP REQUEST；

XN SETUP RESPONSE；

NG-RAN NODE CONFIGURATION UPDATE；

NG-RAN NODE CONFIGURATION UPDATE ACKNOWLEDGE。

s302: when the XN interface message contains a serving Cell Information unit (serving Cell Information NR), whether the external adjacent Cell Information to be added is the external adjacent Cell Information of the sharing party Cell and whether the different manufacturer base station is a single XN IP base station is judged based on the operator attribute of the XN link of the received XN interface message and the operator attribute of the Public Land Mobile Network (PLMN) code contained in the serving Cell Information unit.

The value indicates that the XN link itself has no operator attribute, but each XN link corresponds to one SCTP (Stream Control Transmission Protocol) link, which is an underlying link of the XN link, and each XN interface message is received from a corresponding SCTP link. The operator attribute of the SCTP link is determined by an IP address of the SCTP link home end, the IP address is planned by an operator, and the operator attribute of the SCTP link can be determined when the SCTP link is configured.

In the application, the operator to which the SCTP link belongs can be known by looking up the SCTP link table, and then the operator attribute of the SCTP link is determined.

In this application, the operator attributes of the XN link all represent the operator attributes of the SCTP link corresponding to the XN link.

The operator attribute includes a contractor and a sharing party, and generally, an operator who constructs and opens a network is considered as the contractor, and an operator who directly uses the sharing network is considered as the sharing party.

The PLMN code has a mapping relationship with the operator. As an example, the PLMN code is 46001, and the corresponding operator is operator a; the PLMN code is 46011 and the corresponding operator is operator B.

The process of the base station determining the operator attribute of the XN link or the PLMN code comprises the following steps: the operator to which the XN link or PLMN code belongs, such as operator a, is determined first, and then the operator is identified as belonging to the contractor or the sharer.

In the embodiment of the application, after receiving the XN interface message, whether the Served Cell Information NR structure is carried or not can be directly known.

The XN interface message does not contain the Served Cell Information NR, which indicates that the external neighbor Cell Information of the Cell does not need to be added, and the conventional implementation mode can be maintained.

The XN interface message contains a Served Cell Information NR which indicates that the external adjacent Cell Information of the Cell needs to be added, and in this case, the subsequent judgment step is executed, namely whether the external adjacent Cell Information to be added is the external adjacent Cell Information of the sharing party Cell and whether the different manufacturer base station is a single XN IP base station are judged based on the operator attribute of the XN link of the received XN interface message and the operator attribute of the PLMN code contained in the service Cell Information unit.

Specifically, if the operator attribute of the XN link that receives the XN interface message is the sharing party, it needs to add the external neighboring cell information of the sharing party cell; if the operator attribute of the XN link receiving the XN interface message is a carrier, the external neighbor cell information of the carrier cell needs to be added.

Because the service cell information units in the XN interface messages sent by the single XN IP base station and the dual XN IP base stations have different carrying modes of the PLMN code, it can be determined whether the different manufacturer base station is the single XN IP base station based on the operator attribute of the XN link receiving the XN interface message and the operator attribute of the PLMN code contained in the service cell information unit.

S303: and if the external adjacent cell information to be added is the external adjacent cell information of the sharing party cell and the different manufacturer base station is a single XN IP base station, adding the external adjacent cell information based on the PLMN code in the PLMN extension field in the service cell information unit.

Because the mode of automatically adding the external adjacent cells by the dual XN IP manufacturers is added according to Broadcast PLMNs of the Served Cell Information NR, and the Broadcast PLMNs of the Served Cell Information NR carried in the XN interface message sent by the single XN IP manufacturers is the PLMN of the construction party,

therefore, in the embodiment of the present application, if the external neighbor Information to be added is external neighbor Information of a sharing-side Cell and the inter-manufacturer base station is a single XN IP base station, the external neighbor Information is added based on a PLMN code in a PLMN extension field in the Served Cell Information NR.

Specifically, the PLMN extension field is Broadcast PLMN Identity Info List NR, and since the Broadcast PLMN Identity Info List NR in the XN interface message sent by the single XN IP base station carries the PLMN code of the sharing party, when the external neighboring cell information to be added is the external neighboring cell information of the sharing party cell and the base station of the different manufacturer is the single XN IP base station, the external neighboring cell information is added based on the PLMN code in the Broadcast PLMN Identity Info List NR, which can ensure that the external neighboring cell information is correctly added, and does not require manual operation by a technician.

The method for optimizing the inter-working of the XN links of different manufacturers, provided by the embodiment of the application, receives an XN interface message sent by a base station of the different manufacturers; when the XN interface message contains a serving Cell Information unit (serving Cell Information NR), judging whether the external adjacent Cell Information to be added is the external adjacent Cell Information of the sharing party Cell and whether a different manufacturer base station is a single XN IP base station based on the operator attribute of an XN link of the received XN interface message and the operator attribute of a Public Land Mobile Network (PLMN) code contained in the serving Cell Information unit; the operator attribute comprises a construction party and a sharing party; and if the external adjacent cell information to be added is the external adjacent cell information of the sharing party cell and the different manufacturer base station is a single XN IP base station, adding the external adjacent cell information based on the PLMN code in the PLMN extension field in the service cell information unit.

And even if the external adjacent cell is lost, the information of the external adjacent cell can be automatically added again after the XN interface message is received, so that the normal cell switching is not influenced, and the communication quality of a user in a switching zone is not influenced.

Referring to fig. 4, fig. 4 is a schematic diagram of a determination process in the method for optimizing inter-vendor XN link interworking provided in the embodiment of the present application. In an embodiment of the present application, based on the operator attribute of the XN link that receives the XN interface message and the operator attribute of the PLMN code included in the serving cell information unit, the specific steps of determining whether the external neighboring cell information to be added is the external neighboring cell information of the cell of the sharing party, and whether the base station of the different manufacturer is the single XN IP base station may be:

s401: and judging whether the operator attribute of the XN link receiving the XN interface message is a contractor or not, and if not, executing S402.

S402: and determining that the external neighbor cell information to be added is the external neighbor cell information of the sharing party cell.

Each XN link is configured with an operator attribute to which the link belongs, for distinguishing signaling messages of different operators, so that the base station can determine the operator to which the XN link belongs according to the operator attribute configured by the management station.

If the operator attribute is the carrier, the external neighbor cell information of the carrier cell can be automatically added, so that the existing implementation is maintained.

If the operator attribute is the sharing party, the external neighbor cell information to be added is the external neighbor cell information of the sharing party cell, and subsequent judgment needs to be executed.

S403: and judging whether the address of the opposite end of the SCTP link corresponding to the XN link has the SCTP link of which the operator attribute is the accepting party, if so, executing S404.

S404: and determining the different manufacturer base station as a single XN IP base station.

Specifically, the SCTP link table may be searched to obtain an operator to which the SCTP link belongs, and further determine an attribute of the operator of the SCTP link.

Referring to fig. 5, fig. 5 is a schematic diagram of an SCTP link table, and as shown in fig. 5, a field in a last row of the SCTP link table is an SCTP operator.

For a networking scene of a double XN IP manufacturer X and a single XN IP manufacturer Y, the source ends of two XN links configured by a manufacturer X base station respectively correspond to two IPs of an operator A and an operator B, and the opposite end addresses of the two XN links are the IP addresses of the construction party corresponding to the manufacturer Y base station.

Therefore, the dual XN IP base station can search the whole SCTP link table based on the peer IP address configured by the SCTP link that receives the XN interface message, and further determine whether the peer IP address already has the SCTP link whose operator attribute is the accepting party.

The address of the opposite end has the SCTP link with the operator attribute as the construction party, which shows that the same IP address of the opposite end corresponds to two XN links, thereby determining that the different manufacturer base station of the opposite end is a single XN IP base station.

In an embodiment of the present application, if there is no SCTP link whose operator attribute is a contractor at an opposite-end address of the SCTP link corresponding to the XN link, it cannot be said that the different manufacturer base station at the opposite end is not the single XN IP base station because: if the opposite-end base station is a single XN IP base station, the opposite-end base station may send the message based on the SCTP link whose operator attribute is the sharing party only, but does not send the message based on the SCTP link whose operator attribute is the accepting party, and the opposite-end address does not have the SCTP link whose operator attribute is the accepting party.

Therefore, a further determination needs to be made, that is, whether the operator attribute of the PLMN code included in the NRCGI in the serving cell information element is consistent with the operator attribute of the PLMN code included in the broadcast PLMNs and is a contractor.

Specifically, in an XN interface message sent by a dual XN IP vendor based on an XN link of a sharing party, there are the following two scenarios for the carrying condition of a PLMN:

1) The base station configures a double NRCGI (New Radio Cell Global Identifier) scene, and PLMNs of NRCGI and PLMN of Broadcast PLMNs in a Served Cell Information NR structure in a shared party link XN interface message are configured consistently and are shared party PLMNs.

2) The base station configures a single NRCGI scene, PLMNs of NRCGI in a Served Cell Information NR structure in a sharing party link XN interface message are not consistent with PLMN configuration of Broadcast PLMNs, the PLMNs of NRCGI in the Served Cell Information NR structure carry a construction party PLMN, and the PLMN of Broadcast PLMNs carry a sharing party PLMN.

And the PLMN configuration of the PLMNs of the NRCGI and the PLMN configuration of the Broadcast PLMNs in the Served Cell Information NR structure in the XN interface message sent by the double-XN IP manufacturer based on the XN link of the contractor are consistent and are the PLMN of the contractor.

For a single XN IP manufacturer, PLMNs of NRCGI and PLMN of Broadcast PLMNs in a Served Cell Information NR structure are configured consistently and are PLMNs of the establishing party in XN interface messages sent by links of the sharing party and the establishing party.

Therefore, in order to determine whether the different manufacturer base station of the opposite terminal is the single XN IP base station, it may be determined whether the operator attribute of the PLMN code included in the NRCGI in the serving cell information element of the XN interface message is consistent with the operator attribute of the PLMN code included in the broadcast PLMNs and is a carrier, and if so, it may be determined that the different manufacturer base station of the opposite terminal is the single XN IP base station.

In an embodiment of the present application, after determining that the external neighbor information to be added is external neighbor information of the sharing party cell, it may be determined whether a switch for automatically adding the external neighbor information based on the extension field is turned on.

If the switch for automatically adding the external neighbor cell information based on the extension field is not turned on, the external neighbor cell information of the sharing party cell cannot be automatically added, and under the condition, the existing implementation mode is kept.

And if the switch for automatically adding the external neighbor cell information based on the extension field is opened, executing a step of judging whether an opposite-end address of the SCTP link corresponding to the XN link has the SCTP link with the operator attribute as a construction party.

In an embodiment of the present application, the step of determining whether the external neighboring cell information to be added is the external neighboring cell information of the cell of the sharing party and whether the base station of the different manufacturer is the single XN IP base station based on the operator attribute of the XN link receiving the XN interface message and the operator attribute of the PLMN code included in the serving cell information unit may be:

and judging whether the operator attribute of the SCTP link corresponding to the XN link receiving the XN interface message is consistent with the operator attribute of the PLMN code contained in the broadcast PLMNs in the service cell information unit, if not, determining that the external adjacent cell information to be added is the external adjacent cell information of the sharing party cell, and the base station of the different manufacturer is a single XN IP base station.

Specifically, as described above, in the XN interface message sent by the dual XN IP vendor based on the XN link of the sharing party, there are the following two scenarios for the carrying condition of the PLMN:

1) The base station configures a double NRCGI scene, and PLMNs of NRCGI and Broadcast PLMNs in a Served Cell Information NR structure in a shared party link XN interface message are configured consistently and are shared party PLMNs.

For a single XN IP manufacturer, based on the XN interface message sent by the link of the sharing party and the undertaking party, the PLMN configuration of PLMNs of NRCGI and PLMN of Broadcast PLMNs in the structure of the Served Cell Information NR is consistent and both are PLMN of the undertaking party.

Therefore, as long as the operator attribute of the PLMN of Broadcast PLMNs in the Served Cell Information NR structure is determined to be inconsistent with the operator attribute of the SCTP link corresponding to the XN link that received the XN interface message in the XN interface message, it can be determined that the external neighbor Information to be added is the external neighbor Information of the shared Cell, and the different-manufacturer base station is a single XN IP base station.

It can be seen that, in the embodiment of the present application, it can be determined through the above-mentioned multiple manners that the external neighboring Cell Information to be added is the external neighboring Cell Information of the sharing party Cell, and the inter-manufacturer base station is a single XN IP base station, and in this scenario, the external neighboring Cell Information is added based on the PLMN code in the PLMN extension field in the Served Cell Information NR, thereby implementing automatic addition of the external neighboring Cell Information of the sharing party Cell.

For convenience of understanding, the following describes a process of automatically adding the external neighbor information by the dual XN IP base station in the embodiment of the present application with reference to fig. 6 and fig. 7, where fig. 6 is a schematic flowchart of a process of automatically adding the external neighbor information by the dual XN IP base station in the embodiment of the present application, and fig. 7 is another schematic flowchart of a process of automatically adding the external neighbor information by the dual XN IP base station in the embodiment of the present application.

As shown in fig. 6, in an embodiment of the present application, the process of automatically adding the external neighbor information by the dual XN IP base station may include the following steps:

s601: and receiving an XN interface message sent by an opposite-end different manufacturer base station.

The XN interface message comprises an XN establishment request, an XN establishment response, a configuration update message and the like.

S602: judging whether the received XN interface message contains the Served Cell Information NR or not, if so, executing S603; if not, go to step S609.

If the received XN interface message contains the Served Cell Information NR, external neighbor Cell Information needs to be added, and subsequent judgment is executed; if the Served Cell Information NR is not contained, the external neighbor Cell Information does not need to be added, and the conventional implementation mode is kept.

S603: judging whether the operator attribute of the SCTP link receiving the XN message is a carrier, if so, executing S608; if not, go to S604.

If the operator attribute of the SCTP link receiving the XN message is a construction party, external neighbor cell information of a construction party cell needs to be added, external neighbor cell information of a sharing party cell does not need to be added, namely the problem of incompatibility in the prior art does not occur, and under the condition, the external neighbor cell information in the XN interface message is added according to the existing realization.

If the operator attribute of the SCTP link that received the XN message is not the carrier, that is, the operator attribute of the SCTP link that received the XN message is the sharing party, it is necessary to add external neighbor information of the sharing party cell, and in this case, subsequent determination is performed.

S604: judging whether a switch for automatically adding external neighbor information based on the extension field is turned on, if so, executing S605; if not, go to S608.

S605: judging whether the address of the opposite end of the SCTP link corresponding to the XN link has the SCTP link of which the operator attribute is the accepting party, if so, executing S607; if not, go to S606.

If the opposite-end address has one SCTP link with operator attribute as the establishing party, the opposite-end address corresponds to two XN links, so that the different manufacturer base station of the opposite-end is determined to be a single XN IP base station, under the condition, the external adjacent Cell Information to be added is the external adjacent Cell Information of the sharing party, and the PLMN code of the sharing party is carried in the PLMN extension field in the Served Cell Information NR of the XN interface message, therefore, the external adjacent Cell Information is added based on the PLMN code in the PLMN extension field in the Served Cell Information NR, and the automatic and correct addition of the external adjacent Cell Information of the sharing party Cell can be realized.

S606: judging whether the operator attribute of the PLMN code contained in the NRCGI in the Served Cell Information NR is consistent with the operator attribute of the PLMN code contained in the broadcast PLMNs and is a carrier, if so, executing S607; if not, go to S608.

As described above, if the operator attribute of the PLMN code included in the NRCGI in the Served Cell Information NR is consistent with the operator attribute of the PLMN code included in the broadcast PLMNs and is a contractor, the peer-to-peer heterogeneous manufacturer base station is necessarily a single XN IP base station.

And adding the external adjacent Cell Information based on the PLMN code in the PLMN extension field in the Served Cell Information NR if the external adjacent Cell Information to be added is the external adjacent Cell Information of the sharing party and the opposite-end different manufacturer base station is a single XN IP base station.

S609: the existing implementation is maintained. I.e. no extra external neighbour information of the cell is needed.

As shown in fig. 7, in another embodiment of the present application, the process of automatically adding the neighboring cell information by the dual XN IP base station may include the following steps:

s701: and receiving an XN interface message sent by an opposite-end different manufacturer base station.

S702: judging whether the received XN interface message contains the Served Cell Information NR or not, if so, executing S703; if not, S707 is executed.

If the received XN interface message contains the Served Cell Information NR, external neighbor Cell Information needs to be added, and subsequent judgment is executed; if the Served Cell Information NR is not contained, the external neighbor Cell Information does not need to be added, and the existing implementation mode is kept.

S703: judging whether a switch for automatically adding the external adjacent cell information based on the extension field is turned on, if so, executing S704; if not, go to S706.

S704: judging whether the operator attribute of the SCTP link corresponding to the XN link receiving the XN interface message is consistent with the operator attribute of the PLMN code contained in the broadcast PLMNs in the service cell information unit, if not, executing S705; if yes, go to step S706.

As described above, if the operator attribute of the SCTP link corresponding to the XN link that receives the XN interface message is not consistent with the operator attribute of the PLMN code included in the broadcast PLMNs in the serving Cell Information unit, it may be determined that the external neighbor Information to be added is the external neighbor Information of the sharing-side Cell, and the inter-manufacturer base station is a single XN IP base station, and in this case, the external neighbor Information is added based on the PLMN code in the PLMN extension field in the Served Cell Information NR.

If the operator attribute of the SCTP link corresponding to the XN link receiving the XN interface message is consistent with the operator attribute of the PLMN code contained in the broadcast PLMNs in the service cell information unit, the external neighbor cell information in the XN interface message is added according to the existing realization.

S705: and adding the external neighbor Cell Information based on the PLMN code in the PLMN extension field in the Served Cell Information NR.

S706: and adding the external neighbor information in the XN interface message according to the existing implementation. That is, the external neighbor Information is added according to Broadcast PLMNs of the Served Cell Information NR.

S707: the existing implementation is maintained. I.e. no extra external neighbour information of the cell is needed.

Therefore, based on the two processes, the dual XN IP base station can automatically add the external neighbor information, and for the scenario that the external neighbor information to be added is the external neighbor information of the sharing party and the opposite-end base station is the single XN IP base station of the different manufacturer, the external neighbor information of the sharing party cell can also be automatically added without the manual addition of the technician.
