- the following describes the conversion process in detail by taking the MSC and the BSC to initiate a conversion operation as an example.
- the MSC initiates a conversion operation
- Call. 2 is a flowchart of a method for converting a call mode in which an MSC actively initiates a conversion operation according to an embodiment of the present invention. As shown in FIG. 2, in a call process after a local exchange is established, the MSC actively initiates a conversion operation, and the call mode is initiated.
- the process of the conversion method includes: First, the MSC allocates an A-port circuit for each of the calling parties performing the conversion operation, and establishes an A-port circuit for the calling parties; then, the MSC sends a conversion notification message to the BSC, that is, the local exchange removal in FIG.
- the notification message carries the A port circuit information newly allocated for both parties of the call.
- the MSC sends the conversion notification message and the operation of establishing the A port circuit for the calling parties can determine the sequence according to the flow in the actual operation, and the present invention is not limited thereto.
- the BSC After the BSC receives the local exchange teardown notification message, according to the information of the A port circuit carried in the message, the A port circuit can be separately established for the calling parties, that is, the connection between the calling parties and the A port is established respectively.
- the BSC After the establishment of the A-port circuit, the BSC removes the locally switched user plane link and returns a conversion completion message to the MSC, that is, the local exchange teardown response message in FIG.
- the local exchange teardown notification message sent by the MSC can be in the following two forms:
- the A port circuit of the party indicates the A port circuit allocated to the calling party corresponding to the link transmitting the local exchange teardown notification message
- the other party A port circuit indicates the A port circuit allocated to the other party of the call.
- the A-port circuit information in this embodiment is represented by a TDM format. In actual operation, the A-port circuit information may also be represented by an IP format or other format.
- the MSC actively initiates a conversion operation, notifies the local exchange connection in the base station controller to be removed, and re-establishes a new A-port circuit, thereby converting the local exchange to the non-local exchange, thereby avoiding the local exchange mode during the BSC handover. The resulting call failure has improved the performance of the system.
- the BSC actively initiates a conversion operation, and the base station controller sends a conversion request message to the mobile switching center, where the conversion request message is used to request to initiate a conversion of the call mode; and in response to the conversion request message, the mobile switching center sends the conversion to the base station controller. Notification message. Specifically, if the base station controller supports the A-port circuit allocation, the base station controller may allocate the A-port circuit to the calling parties, and the conversion request message sent to the MSC at this time includes the information of the A-port circuit allocated by the base station controller to the calling parties.
- the mobile switching center After receiving the conversion request message, the mobile switching center does not need to allocate the A port circuit to the calling parties, and the mobile switching center establishes the A port circuit for the calling parties according to the conversion request message. Then, the MSC sends a conversion notification message to the BSC, where the conversion notification message may carry the information of the A port circuit in the conversion request message, or may not carry the information. After the BSC receives the conversion notification message, the BSC can establish an A-port circuit for the calling parties to implement a local call exchanged by the Y. Of course, if the base station controller does not support the A-port circuit allocation, the conversion request message sent to the MSC is only used to request the initiation of the conversion of the call mode.
- FIG. 3 is a flowchart of a method for converting a call mode in which a BSC actively initiates a conversion operation according to an embodiment of the present invention.
- a BSC actively initiates a conversion operation, where, BSC Supporting the A-port circuit allocation
- the flow of the call mode conversion method includes: First, the BSC sends a conversion request message to the MSC, that is, the local exchange teardown request message in FIG.
- the BSC Since the BSC supports the A-port circuit allocation, the BSC allocates the A-port circuit to the calling parties, and carries the information of the assigned A-port circuit in the local exchange teardown request message to the MSC. If the BSC does not support the A-port circuit assignment, the BSC cannot allocate the A-port circuit to the calling parties. At this time, the sent local exchange teardown request message is only used to request to initiate the switching operation of the call mode.
- the MSC After receiving the local exchange teardown request message, the MSC determines whether it is necessary to allocate the A port circuit for this conversion operation. If the local exchange teardown request message carries the information of the A port circuit, the MSC does not need to be allocated again, and only needs to confirm the information of the A port circuit; if the local exchange teardown request message does not carry the information of the A port circuit, That is, if the BSC does not allocate the information of the A port circuit, the MSC needs to allocate the A port circuit for each of the calling parties.
- the MSC establishes a connection of the A port circuit for the calling parties according to the allocated A port circuit, and sends a conversion notification message, that is, the local exchange teardown notification message in the figure to the BSC. If the BSC does not allocate an A-port circuit, the local exchange removal notification message carries the information of the assigned A-port circuit. If the BSC allocates the A port circuit, it may or may not carry the information of the allocated A port circuit in the local exchange teardown notification message.
- the BSC After receiving the local exchange teardown notification message, the BSC establishes a connection to the A port for both parties. After the establishment is completed, the BSC removes the locally switched user plane link and returns a local exchange teardown response message to the MSC.
- the information of the A port circuit here may be the two forms described above, and will not be mentioned here.
- the BSC actively initiates a conversion operation to notify the MSC of the conversion notification message. After the BSC receives the conversion notification message, the BSC uses the information of the A-port circuit carried in the conversion notification message as the locally exchanged caller.
- the A-port circuit is established to convert the local exchange to the non-local exchange, which avoids the call failure caused by the local exchange mode during the BSC handover, thereby improving the performance and stability of the system.
- the call mode caused by the handover between the BSCs or the BSCs is respectively taken as an example to The embodiment of the invention will be described in detail.
- FIG. 4 is a schematic diagram of a flow of inter-BSC handover in the related art.
- the BSC finds that an inter-BSC handover is required, and the BSC sends a handover request (Handover Required) to the MSC.
- the MSC determines that the handover is an inter-BSC handover, and sends a handover request message (Handover Request) to the handover BSC of the handover user, and carries the information of the A interface circuit allocated for the handover user in the handover request message.
- the cut-in BSC is for the handover user to activate the channel (Channel Active) on the cut-in BTS, and waits for the handover user to access. After the user accesses and the handover is completed, the handover user sends a handover complete message (Handover Complete), and the handover user starts to use the newly allocated A-port circuit to perform user plane data exchange. In the case of a local exchange of calls, switching between BSCs may result in local exchanges not being applicable.
- FIG. 5 is a schematic diagram of a call mode transition in a handover process between BSCs according to an embodiment of the present invention. As shown in FIG. 5, after receiving the handover request message (Handover Required), the MSC determines that the handover will result in local handover.
- the MSC actively initiates a call mode conversion operation.
- the process of switching users in the conversion process of the call mode is the same as that in the related protocol, and remains unchanged, and details are not described herein again.
- the MSC After the handover between the BSCs (Handover Complete), the MSC initiates a call mode conversion operation, and sends a local exchange teardown request message to the BSC where the unswitched user (ie, the hold user in the figure) is located, and removes the local exchange link for the unswitched user.
- FIG. 6 is a schematic diagram of a process of intra-BSC handover in which the AoverIP (ie, AoIP, A port circuit is implemented by IP) is not implemented in the related art.
- the BSC masters the entire handover procedure without local switching. After receiving the measurement report, the BSC initiates a handover.
- the BSC After the handover is completed, when the handover user sends a handover, after the completion message (Handover Complete) is sent to the BSC, the BSC sends a Handover Performed message to the MSC for notification.
- the BSC finds that the intra-BSC handover is required, the BSC must consider whether the local exchange can be continued after the handover. If the BSC finds that the local exchange cannot be maintained after the handover, the local call mode conversion operation shown in FIG. 7 is actively initiated. As shown in FIG. 7, the local call mode conversion operation is the same as the BSC initiatively initiates the conversion operation. BSC does not support A port allocation), so I won't go into details here.
- FIG. 8 is a schematic diagram of a flow of implementing intra-BSC handover of AoverIP in the related art.
- the BSC when there is no local exchange, after the BSC receives the measurement report and determines that handover within the BSC is required, the BSC sends an Internal Handover Required message to the MSC, and the MSC returns to the internal handover port.
- the Internal Handover Command message the BSC starts the channel active (Channel Active), waiting for the switching user to access.
- the handover user sends a handover complete message (Handover Complete), and the BSC notifies the MSC that the handover is completed.
- the entire handover process needs to be completed through message interaction between the BSC and the MSC.
- the BSC In the case of local switching, when a BSC internal handover occurs, the BSC must determine whether the local exchange can still be maintained after the internal handover is completed. If the local exchange cannot be maintained, the local call mode conversion operation shown in FIG. 9 is initiated. As shown in FIG. 9, the BSC may initiate a call mode conversion operation before the handover starts, specifically, the local call mode conversion operation. The same as the above-mentioned BSC initiatively initiates the conversion operation, and details are not described herein again.
- FIG. 10 is a schematic diagram of a local call mode switching operation in a BSC intra-switching process for implementing AoverIP according to an embodiment of the present invention.
- the BSC finds that it cannot be maintained after the internal handover.
- the local exchange carries the local exchange teardown request in the Internal Handover Required message.
- the MSC After receiving the local exchange teardown request, the MSC allocates the A port circuit to the switcher in the Internal Handover Command. At the same time, the A port resource reassignment message is used to reassign the user plane resource to the non-switching party. After receiving the handover complete message (Handover Complete), the MSC sends a local exchange teardown request notification. After the local exchange is removed, the calling parties exchange user plane data through the newly allocated A-port circuit, which ensures the communication quality of the locally exchanged call users and improves the user experience.
