Description

TECHNICAL FIELD The present invention relates to communications technologies, and in particular, to a signaling processing method, device, and system. Background technique

In the mobile communication system, with the continuous development of the wireless network, the network architecture and the networking mode are also rapidly developing. A device pool of multiple devices has emerged, so that the device pool has high capacity for disaster recovery and load sharing. For example, the RNC POOL (Radio Network Controller POOL) is composed of a plurality of RNCs (Radio Network Controllers) distributed in different places, and each RNC in the RNC POOLs jointly carries a logical RNC. For each service, each RNC in the pool can be referred to as a physical RNC. When the traffic of a physical RNC in a pool is high or faulty, the traffic carried by the physical RNC can be shared by other physical RNCs in the pool. This allows the RNC POOL to have the capability of RNC disaster recovery and equalization of RNC processing capabilities.

In the prior art, in order to improve the processing capability of the RNC, each physical RNC in the RNC POOL is configured with multiple SPUs (Signaling Process Units), and the SPUs on each RNC in the pool are configured the same. M3UA (Message Transfer Part 3- User Adaptation Layer) information of the third-level user of the message transmission part, and each M3UA information element in the pool maintains a consistent link state table, that is, for maintenance All physical link states from the source signaling point (ie, logical RNC) to the destination signaling point (eg, a core network device) within the RNC POOL, the physical link is hashed on each RNC in the pool to When a certain RNC is able to receive a call signaling, it can arbitrarily select a physical link to transmit the call signaling according to the link state table maintained by the RNC, thereby implementing disaster tolerance or load sharing of the pool.

However, as described above, since each M3UA unit maintains the state of the physical link on all RNCs in the RNC POOL, when an RNC state changes, such as joining or exiting the RNC POOL, the SPUs of the RNCs are The status update information is transmitted to each other, thereby causing a broadcast storm caused by the status update in the RNC POOL.

The technical solutions in the present invention will be clearly and completely described in the following with reference to the drawings of the present invention. It is obvious that the described embodiments are part of the present invention. Embodiments, not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The embodiment of the present invention improves the deployment mode of the M3UA in the device pool. To make the description of the method in the embodiment of the present invention more clear, the deployment of the M3UA on the RNC in the embodiment of the present invention is first described:

FIG. 1 is a schematic diagram of a method for deploying an M3UA in an RNC according to an embodiment of the present invention. As shown in FIG. 1 , an RNC pool 103 may include multiple physical RNC devices, and each physical RNC device in the RNC pool is connected to each other. The RNC device 104 and the RNC device 105 are depicted. RNC pool 103 is connected to the base station 101 and the base station 102, and is connected to the core network 106. The logical M3UA and the physical M3UA are deployed in each signaling processing unit SPU of each physical RNC device in the RNC pool. The original logical RNC corresponding to the RNC pool is deployed to the M3UA layer of the core network as a logical M3UA. However, no route and link are configured in the logical M3UA. Each physical RNC independently configures the physical RNC to the physical M3UA of the core network. The physical M3UA contains routing and link information of the RNC device to which it belongs to the core network.

When receiving the service message sent by the base station, the physical RNC obtains the source signaling point, the destination signaling point, and the routing context information of the service according to the service information and the configuration information, and searches for the source information of the service signaling in the logical M3UA. The logical M3UA record corresponding to the point, the destination signaling point, and the routing context is recorded. The logical M3UA records the reachability status of the device to the destination signaling point in the RNC pool, and determines that the current signaling processing RNC device can reach the destination signaling. In the case of the point, the signaling processing RNC device records the mapping relationship with the physical M3UA according to the logical M3UA, and obtains the physical M3UA record. The physical M3UA records the route and link of the signaling processing RNC device to the destination signaling point. The mapping relationship is that the logical M3UA and the physical M3UA contain the same destination signaling point and routing context, and the routing context is a specific identifier for the application-free service.

2 is a flowchart of Embodiment 1 of a signaling processing method according to the present invention. As shown in FIG. 2, the method in this embodiment may include:

5201. The signaling processing device receives the service signaling to be sent to the destination signaling point.

Specifically, the signaling processing device is any signaling processing device in the signaling processing device pool, and the signaling processing device receives the RRC connection request sent by the base station, and after completing the RRC connection, according to the service information carried by the user equipment and The configuration information is used to obtain the service signaling that needs to be transmitted to the core network. The service signaling includes: source signaling point information, destination signaling point information, and routing context information corresponding to the service signaling, where the destination signaling point identifies the service. The signaling point is to reach the destination address of the core network, and the routing context can identify the service type to which the service signaling belongs.

5202. The signaling processing device obtains a logical M3UA record according to the source signaling point information, the destination signaling point information, and the routing context information.

Specifically, the signaling processing device acquires source signaling point information, destination signaling point information, and routing context information of the service signaling, because the logical M3UA record includes the destination signaling point information and the routing context information of the device pool to the core network, The signaling processing device can be based on the source of the service signaling The signaling point information, the destination signaling point information, and the routing context information are found by looking up the logical M3UA record to find the logical M3UA record corresponding to the service signaling.

The logical M3UA record further includes: the reachability status information of the signaling processing device itself to the destination signaling point, but the logical M3UA record does not include the routing and link information of the signaling processing device to the destination signaling point. If it is determined that the destination signaling point is unreachable according to the reachability state information, the signaling processing device reports information that cannot transmit the service signaling to the destination signaling point to the upper application layer.

S203. If it is determined that the destination signaling point is reachable according to the reachability state, the signaling processing device obtains the physical M3UA record according to the mapping relationship between the logical M3UA record and the physical M3UA record.

Specifically, each physical signaling processing device independently configures the physical signaling processing device to the physical M3UA of the core network, where the physical M3UA record includes the destination signaling point information and the routing context of the signaling processing device reaching the core network, and the physical M3UA record It also includes routing and link information for the signaling processing device itself to reach the destination signaling point. Physical M3UA records and logical M3UA records with mappings need to include the same destination signaling point information and routing context information. The signaling processing device obtains the physical M3UA record according to the mapping relationship between the logical M3UA record and the physical M3UA record, that is, the signaling processing device obtains the route and link information of the signalling point that reaches the destination.

The mapping relationship between logical M3UA records and physical M3UA records can be recorded by establishing a mapping relationship table. For example, suppose the key values of the logical M3UA table include (1—index, opc, dpc, rtcontext), the key values of the physical M3UA table include (p—index, opc, dpc, rtcontext), and 1—index is the index of the logical M3UA table. No., p—index is the index number of the physical M3UA table, opc is the source signaling point, dpc is the destination signaling point, and rtcontext is the routing context. First, all records of the physical M3UA table are queried for each record of the logical M3UA table. When the key values of dpc and rtcontext in the logical M3UA record are equal to the key values of dpc and rtcontext in the physical M3UA record, a mapping record is created: (m_index, 1-index, p-index), m-index The index number of the mapping relation table.

For example, if there are three signaling processing devices RNC1, RNC2, and RNC3, if the RNC pool is not formed, the corresponding source signaling points are rl, r2, and r3, respectively, and can reach the signaling point aa of the core network. The routing context is Rtcontext, then the M3UA records of RNC1, RNC2, and RNC3 are: ( rl , aa , rtcontext );

( r2, aa, rtcontext ) ;

( r3 , aa, rtcontext ). After RNC1, RNC2, and RNC3 form an RNC pool, the M3UA of each physical RNC in the RNC pool includes: a logical M3UA and a physical M3UA. Taking the physical RNC1 and the physical RNC2 as examples, the source signaling points of the physical RNC1 and the physical RNC2 are respectively pi and p2, and then the logical M3UA of the physical RNC1 is recorded as:

( rl , aa, rtcontext ) lidxl;

( r2, aa, rtcontext ) lidx2;

( r3 , aa , rtcontext ) lidx3.

Among them, lidxl , lidx2 and lidx3 are the index numbers of the logical M3UA records.

Physical RNC1's physical M3UA record is:

( pi , aa , rtcontext ) pidxl.

Where pidxl is the index number of the physical M3UA record of the physical RNC1.

Then, in physical RNC1, the mapping relationship from logical M3UA to physical M3UA is recorded as:

( lidxl , pidxl ) ;

( lidx2, pidxl ) ;

( lidx3 , pidxl ).

Physical RNC2 logic M3UA records as:

( rl , aa, rtcontext ) lidxl;

( r2, aa, rtcontext ) lidx2;

( r3 , aa , rtcontext ) lidx3.

Physical RNC2's physical M3UA record is:

( 2, aa, rtcontext ) pidx2

Where pidx2 is the index number of the physical M3UA record of the physical RNC2.

Then, in physical RNC2, the mapping relationship from logical M3UA to physical M3UA is recorded as:

( lidxl , pidx2 ) ;

( lidx2, pidx2 ) ;

( lidx3 , pidx2 ).

In this embodiment, the logical M3UA in each physical RNC in the RNC pool is the same, indicating All the original logical RNCs are to the M3UA of the core network; the physical M3UAs in the physical RNCs in the RNC pool are different (the source signaling points are different), and the mapping relationships in the physical RNCs in the RNC pool are also independent, therefore, When the state of a physical device in the device pool changes, the state change information does not need to be broadcast to other physical devices in the device pool. Therefore, broadcast storms in the device pool can be reduced.

S204. The signaling processing device transmits the service signaling to the destination signaling point according to the routing and link information.

The signaling processing device transmits the service signaling to the destination signaling point according to the routing and link information of the signaling point reaching the core network in the physical M3UA record.

In this embodiment, after receiving the service signaling, the signaling processing device first obtains the source signaling point information and the destination letter of the service signaling by using the source signaling point information, the destination signaling point, and the routing context information of the service signaling. The logical M3UA records with the same point are recorded, and the physical M3UA record is obtained according to the mapping relationship between the logical M3UA record and the physical M3UA record, and the routing and chain of the destination signaling point of the signaling processing device itself to the service signaling is obtained from the physical M3UA record. Road information. Since the logical M3UA record does not include routing and link information, the physical M3UA record is independently configured in each signaling processing device, and the routing and link information included in the physical M3UA record is the signaling processing device itself arrives at the destination signaling point. Route and link information. Therefore, the routing and link information between the signaling processing devices in the device pool need not be synchronized, and the processing operations such as sending and receiving service signaling do not need to span multiple signaling processing devices. Therefore, not only can broadcast storms in the device pool be reduced, but also the processing efficiency of service signaling can be improved.

The signaling processing method as described above, wherein the signaling processing device includes at least one signaling processing unit SPU, and each of the SPUs stores the logical M3UA record and the physical M3UA record. The physical M3UA record in each of the SPUs is specifically configured to store all routing and link information that the signaling processing device itself reaches the destination signaling point, where all link information is hashed in the And in the at least one SPU; and, each of the SPUs is configured to maintain a link state corresponding to the route and link information managed by the SPU itself.

In a specific application, in order to improve the processing capability of the signaling processing device, multiple signaling processing units SPU are often configured in a single signaling processing device, and the physical link of the signaling processing device reaching the signaling point of the core network is hashed. On each signaling processing unit SPU of the signaling processing device, a single SPU only needs to manage the physical links on the hash and maintain the state of the physical link. The signaling processing method as described above, wherein each SPU maintains a link state corresponding to the link information managed by itself, and the first SPU in the signaling processing device sends the link state of the physical M3UA record stored therein. To the second SPU within the signaling processing device.

The first SPU refers to a signaling processing unit that transmits link state information, and the second SPU refers to a signaling processing unit that receives link state information. Transmitting, by the first SPU in the signaling processing device, the link state stored in the physical M3UA record to the second SPU in the signaling processing device, so that the second SPU updates the corresponding chain in the physical M3UA record. Road status. Specifically, the first SPU periodically sends the link status to the second SPU, where the link status is a link status corresponding to the link information managed by the first SPU, and the second SPU includes the All SPUs except the first SPU in the signaling processing device;

Specifically, each SPU subsystem in the physical signaling processing device periodically sends the M3UA link state information managed by the subsystem to other SPU subsystems in the physical signaling processing device to which it belongs, and receives the SPU of the link state information. The subsystem updates the corresponding link state information in the physical M3UA record stored by the subsystem, and sends an acknowledgement message to the SPU that sends the link state information, indicating that the link update message has been received, and the SPU that sends the link state information waits for a period of time. After that, if the acknowledgment message is not received, the link state information is retransmitted.

Or the first SPU sends the changed link state to the second SPU when the link state of the self-managed link changes, and the second SPU includes all but the first SPU in the signaling processing device. SPU;

Specifically, when the status of the M3UA link managed by a certain SPU subsystem in the physical signaling processing device changes, the SPU sends the new status to all other SPUs in the physical signaling processing device to which it belongs, and receives the The SPU of the message updates the received link update information to the corresponding link state information in the physical M3UA record stored therein, and sends an acknowledgement message to the SPU that sends the link state update information, indicating that the link update message has been received. The SPU that sends the link state update information resends the link state update information if it does not receive the acknowledgment message after waiting for a period of time.

Or, when the first SPU detects that the second SPU is changed from the fault to the normal state, the physical processing device that stores the physical M3UA record of the first SPU records all routing and link information of the destination signaling point and A corresponding link state is sent to the second SPU.

Specifically, when an SPU subsystem in the physical signaling processing device detects the physics to which it belongs When the status of other SPU subsystems in the signaling processing device changes from fault to normal, the signaling processing device stored in the physical M3UA record stored in the SPU subsystem reaches the SPU subsystem of the destination signaling point, and the fault is caused by the fault. After receiving the above information, the SPU subsystem that becomes normal updates the corresponding information in the stored physical M3UA record, and sends an acknowledgement message to the sender, indicating that the above information has been received, and the SPU that sent the information waits for a period of time. If the confirmation message is not received, the above information is resent.

Or, the first SPU sets all link states managed by the second SPU of the physical M3UA record of the first SPU to a fault when detecting that the second SPU changes from normal to fault.

Specifically, when a certain SPU subsystem in the physical signaling processing device detects that the status of other SPU subsystems in the physical signaling processing device to which it belongs changes from normal to failure, the physical M3UA record stored in the SPU subsystem is recorded. All link states managed by the corresponding fault SPU are set to faults.

In this embodiment, each SPU subsystem in the signaling processing device independently manages the physical link state of the hashing allocation of the signaling processing device to which it belongs, and periodically sends status information to other SPUs of the signaling processing device to which it belongs. When the physical link of the management changes, or when other SPU status changes of the signaling processing device to which it belongs are monitored, the relevant M3UA records the synchronization of the physical M3UA in the signaling processing device to improve the system. reliability.

The signaling processing method as described above, wherein each of the SPUs maintains a link state corresponding to the link information managed by the SPU, and may further include:

Each SPU in the signaling processing device records the reachability of the logical signaling processing device to the signaling point of the core network according to the mapping relationship between the logical M3UA record and the physical M3UA record.

FIG. 3 is a flowchart of Embodiment 2 of the signaling processing method of the present invention. As shown in FIG. 3, on the basis of the foregoing embodiments, the uplink processing method for the service signaling from the signaling processing device to the core network may include: 5301. The signaling processing device establishes a connection with the base station, and receives a service message initiated by the user terminal. Specifically, when the user terminal initiates a call through the base station, the physical signaling processing device first establishes an RRC (Radio Resource Control) connection with the base station, and receives the paging service message service information and configuration information sent by the base station. The source signaling point information, the destination signaling point information, and the routing context information of the service are included, and the destination signaling point identifies the destination address of the service signaling point to reach the core network, and the routing context may identify the service type to which the service signaling belongs.

5302. The signaling processing device establishes a connection with the core network.

After completing the RRC connection with the base station, the signaling processing device initiates a connection to the core network, so that the transport layer can transmit the service signaling to the core network.

5303. The signaling processing device searches for a logical M3UA record according to the source signaling point and the destination signaling point of the service signaling.

The signaling processing device may search the logical M3UA record according to the source signaling point information, the destination signaling point information, and the routing context information of the service signaling, and obtain the source signaling point, the destination signaling point, and the routing context with the service signaling point. All have the same logical M3UA record.

5304. The signaling processing device determines that the destination signaling point is reachable according to the reachability state in the logical M3UA record.

The logical M3UA record includes reachability status information from the signaling processing device itself to the destination signaling point. The reachability of the destination signaling point record recorded by the logical M3UA is completely determined by the physical M3UA record with which the mapping relationship is established. When all the mapped physical M3UAs to the destination signaling point are unreachable, the logical M3UA records the destination. The status of the signaling point is not reachable.

5305. The signaling processing device obtains a physical M3UA record according to a mapping relationship between the logical M3UA record and the physical M3UA record.

Physical M3UA records and logical M3UA records with mappings need to include the same destination signaling point information and routing context information.

5306. The signaling processing device selects a route and a link for the service signaling, and transmits the service signaling to the destination signaling point.

The physical M3UA record includes the routing and link information of the signaling processing device itself to the destination signaling point, the routing management link state, and the signaling processing device updates the routing state through the link state.

The signaling processing device obtains all the logical M3UA records corresponding to the physical M3UA records according to the mapping relationship between the logical M3UA records and the physical M3UA records, and selects the source signaling point information and the service letter recorded by the logical M3UA from the corresponding logical M3UA records. Let the other logical M3UA record to be sent to another destination signaling point. Physical M3UA records and logical M3UA records with mapping relationships also need to include the same destination signaling point information and routing context information.
