Description

Network interworking, service node and upper-layer user's interoperability methods and device

Technical field

The present invention relates to the interoperability methods in the communication system, relate in particular to network interworking, service node and upper-layer user's interoperability methods and device.

Background technology

At present be mainly used in the No.7 signaling network that the work of speech business speech channel net is provided as guidance, it not only can be used for transmitting transmitting between the required interoffice signaling of circuit connection in telephone network and the integrated services digital network but also moving exchanging center MSC that can be in mobile radio communication, access location logger VLR, the home location register HLR roams relevant all places information with the user; Transmit various information between operation exchange SSP in intelligent network, service control point (SCP) and the ip intelligent peripherals IP; Various IN services are finished in support; Can also in the No.7 signaling network, transmit various operations, maintenance and management information.

No.7 signaling system agreement is divided into two parts: User Part (UP), message transfer part (MTP).Wherein, message transfer part can be divided into again: MTP-1 signaling data link level (signaling data linklevel), MTP-2 signaling link level (signaling link level), MTP-3 signaling network functions level (signalingnetwork level).

MTP-3 signaling network functions level.Mainly finish the routing and the signaling network management function of signaling message.Signaling network functions transfers a message to the signalling point of appointment according to the address information of message elements.Signaling network management function monitors the work of each signalling route and signaling link.

Because the MTP-3 routing function is difficult to transmission and calling and the irrelevant signaling message of circuit, and along with the development of telecommunication service, increasing service needed transmission and circuit and the irrelevant signaling message of calling, as: the various control informations between SSP and the SCP, the transmission of the various roaming informations of transmission terminal, mobile short-message and reception or the like between MSC and VLR and the HLR.For this reason, this is positioned at functional level on the MTP-3 and function that MTP-3 finishes network layer together to have introduced SCCP.

SCCP (Signalling Connection Control Part, SCCP) agreement provides towards the data transmission service end to end of connection and connectionless-mode the upper-layer protocol user.SCCP belongs to network and transport layer functionality level in the network hierarchy structure, the calling and called address that SCCP can provide according to the user, the function that cooperates No.7 signaling network MTP message transfer part, finish the network routing addressing function of SCCP between signaling node, SCCP also can connect for the upper-layer user (or need not to connect) and transmitting user data between signaling node simultaneously.

SCCP network routing addressing function cardinal principle and this mode of IP are very similar, just SCCP is according to the calling and called address in the SCCP message, parsing finds out next and jumps destination address, the key message of SCCP primary circuit routing routing is the DPC in the calling/called information (Destination (signalling) Point Code destination signaling point), SSN (Sub-System Number Sub-System Number) or GT (Global Title global title).

Below we simply introduce the key message of SCCP routing addressing:

1) destination signaling point (DPC): No.7 signaling element address of node sign (similar IP address), the coding of 14 or 24 bit lengths normally, the address of certain network element device of sign in certain specific No.7 network;

2) Sub-System Number (SSN): the logical number of the upper-layer service subsystem of SCCP service, SCCP can provide service for multiple upper-layer user simultaneously, as being wireless MAP, BSSAP, RANAP etc., also can be business such as intelligent network INAP, CAP, so in order to distinguish these professional SSN Sub-System Number signs of having introduced;

3) global title (GT): another geocoding form, because the DPC coding range of No.7 is less, so DPC may not be unique in the No.7 in country variant area network, introduce a GT global title mode that scope is bigger, can guarantee the uniqueness of GT sign indicating number in network like this.

For the route messages process of simple declaration SCCP, as shown in Figure 1, with the signaling node of SCCP is abstract be: originating point (A1), relay point (B1, Y1), point of destination (Z1).SCCP message route selection is from originating point A1, arrives final SCCP point of destination Z1 through relay point B1, Y1 routing addressing.

When the SCCP route selection, will find next-hop address information according to information in the called address (DPC/SSN/GT) and networking configuration information.In general, the routing addressing of SCCP is to carry out according to following principle:

Jump down after the DPC+ route translation GT and (or) SSN;

Route results is if during next hop information, must comprise time to jump DPC, and can produce during the route translation new GT or (with) SSN is as its result, when not excessive GT and SSN existed simultaneously, needing next jumping of decision still be the SSN addressing according to GT.At present, different with the position of network element in network different according to the difference of networking mode with the role, adopted the addressing system of DPC+SSN or DPC+GT respectively; The A mouth of wireless access network for example, BSC/RNC and MSC substantially are based on the addressing system of DPC+SSN.

Along with the application and the popularization of Softswitch technology, the conventional telecommunications net just develops towards the direction with the IP network intercommunication.Wherein, the problem of most critical is that the No.7 signaling that has been used widely can transmission efficiently and reliably in IP network.As far back as 1999, IETFInternet engineering duty group (Internet Engineering TaskForce) just begins to formulate SIGTRAN (Signalling transport) protocol family based on the IP technology, it mainly comprises the adapting protocol of No.7 signaling system MTP layer, so that the transmittability of No.7 signaling on IP network to be provided.At present, IETF has further proposed the adapting protocol of SCCP layer again--SUA (SignallingConnection Control Part User Adaptation Layer, signaling connection control part customer message adaptation layer) agreement, so that stronger map addresses and routing function to be provided, and simpler management function.

Similar SCCP on the function that the SUA agreement provides the upper-layer user, different is that the transmission of SUA lower floor is based on the SCTP/IP agreement, and the SUA agreement is expanded the routing addressing information of SCCP, except comprising DPC/SSN/GT, can also use IP address and Hostname to carry out addressing.Can increase to some extent with respect to SCCP route results SUA like this:

1) GT and/or SSN after jumping IP+ route is translated down

2)hostname

And on the basis that the SUA agreement has been arranged,, introduced SGW SG (Signalling Gateway, SGW) equipment in order to realize No.7 signaling network and IP-based SUA signalling network interconnection.Referring to Fig. 2, node A, B, C are NO.7 side SCCP nodes among the figure, and nodes X, Y, Z are the SUA nodes of IP side, and D is SGW SG, and SG is connected with the SUA node with each SCCP node.SG is as the bridge that connects NO.7 and IP signaling net, when carrying out the message route, be responsible for finishing the message route between SCCP and SUA, according to agreement regulation and general at present the application, NO.7 side SCCP signalling point and IP side SUA signalling point they mutually can not be directly as seen, have only SCCP and the SUA node that to see both sides on the SG simultaneously, therefore the SCCP user message is when NO.7 side SCCP is routed to IP side SUA, or from user message when IP side SUA is routed to NO.7 side SCCP, generally translation is routed to corresponding SCCP or SUA signaling node through GT.

As shown in Figure 3, traditional NO.7 network addressing mode is: 10 are BSC (Base Station Controller base station controller)/RNC (Radio Network Controller radio network controller), and 11 is MSC (Mobile Service Switching Center mobile services switching centre); BSC/RNC (10) and MSC (11) route are the addressing systems by DPC+SSN recited above; As shown in Figure 4, on the basis of Fig. 3, for SG (12) has been introduced in the network interworking that realizes NO.7 and IP.After introducing SG (12), BSC/RNC (10) carries out GT translation route with MSC (11) route by SG (12).

SCCP signaling node because of original two direct neighbors, obviously user message can be by direct DPC+SSN mode routing addressing between them, one of them upgrading replaces with based on SUA protocol signaling node, like this in order to realize that business intercommunication just need introduce SG (12) SGW between them, from top we see by this at SG (12) and be to use GT translation route, this also just means for the employed direct DPC+SSN route addressing mode of traditional SCCP node users message, must be changed to translating route by GT, the network configuration and the addressing system that also are original user need to revise, so just the change to traditional NO.7 network is bigger, has caused impact.

In addition after the intercommunication that has realized NO.7 and IP network, regulation based on the SUA agreement, also should guarantee the primitive interface seamless transitions between the SCCP user on SUA and upper strata, but we can see addressing owing to SUA strengthens of mentioning upward, so just need to expand the standard N primitive between SUA and the SCCP upper-layer user, with IP and the Hostname address format supporting to increase newly, just change has taken place in service primitive between the SCCP user on upper strata and the SUA.Service primitive described herein promptly refers to carry out between adjacent layer a kind of operation primitive of information interaction.

In sum, though prior art can realize the intercommunication of NO.7 and IP network, owing to need carry out network configuration to the signaling node of traditional NO.7 and addressing system is changed; And realizing the SUA and upper-layer user's primitive interface seamless transitions of SUA agreement regulation, also need service primitive between the SCCP user on upper strata and the SUA is changed, is not very desirable from efficient and cost consideration.

Embodiment

The problem that the embodiment of the invention will solve is in the network interworking of signaling node of traditional NO.7 not being carried out realizing under the situation that network configuration and addressing system change NO.7 and IP; And realize SUA and upper-layer user's primitive interface seamless transitions under the situation that service primitive is changed between not needing the SCCP user on upper strata and SUA.

The total thinking of the embodiment of the invention is as follows, after the SCCP of traditional NO.7 application mode evolves to IP-based SUA agreement, traditional SCCP signaling node, for example the BSC/RNC radio reception device directly is linked on the SG, still use original DPC+SSN addressing, networking mode, and by in network, introducing " map addresses " function, make between traditional SCCP signaling node and SUA signaling node, can realize network interworking.

Following mask body is introduced the implementation method of the embodiment of the invention:

The SCCP signaling node sends the embodiment 1 of message to the SUA signaling node, referring to Fig. 5:

Step 101:BSC/RNC sends SCCP message according to original networking application mode to core net SG.

Carry OPC (the original signalling point of Original Point Code) information (promptly sending the BSC/RNC address information of this message), DPC information (the DPC information of this moment is the address information of SG) and SSN information in this message.

Step 102: receive the SCCP message of BSC/RNC transmission as SG after, by map addresses, find the MSC address information that BSC/RNC belonged to that sends this message according to the OPC message of carrying in the message (promptly sending the BSC/RNC address information of this message) based on the SUA agreement.

Map addresses function described in this step can be searched by OPC message (promptly sending the BSC/RNC address information of this message) that sets in advance and the MSC address information mapping table based on the SUA agreement that BSC/RNC belonged to that sends this message.

Step 103:SG is to find the MSC address information that BSC/RNC belonged to that sends this message with the DPC information change that carries in the information.

To more the correct one's mistakes message conversion of DPC information of step 104:SG is the SUA message format, and sends to purpose MSC.

Step 105: described MSC receives this SUA message, and handles accordingly.

For example, the address of supposing BSC/RNC is 1000, and the address of SG is 2000, and the address of MSC is 3000.BSC/RNC sends SCCP message according to original networking application mode to core net SG, carries OPC=1000, DPC=2000 and SSN=MAP in this message.

After SG received this message, by map addresses, finding the MSC address based on the SUA agreement that BSC/RNC belongs to was 3000.SG changes to 3000 with the DPC in the message, and this message format is converted to the SUA message format, will carry OPC=1000 again,, the message of DPC=3000 and SSN=MAP sends to MSC, MSC handles accordingly according to the message of receiving.So far, just finished based on the SCCP signaling node to communication based on the network of SUA signaling node.

Corresponding to this method, the embodiment of the invention also provides a kind of map addresses device, and this device comprises: memory cell, search unit, receiving element, transmitting element;

Receiving element is used to receive the address information of the BSC/RNC that SG sends,

Memory cell is used to store the MSC address information corresponding relation based on the SUA agreement of BSC/RNC address information and its ownership;

Searching the unit is used for address information to memory cell by BSC/RNC and finds out the MSC address information based on the SUA agreement with its ownership;

The MSC address information based on the SUA agreement that BSC/RNC belonged to that transmitting element is used for finding feeds back to SG.

The SCCP signaling node sends the embodiment 2 of message to the SUA signaling node, referring to Fig. 6:

Step 201:BSC/RNC to it belonged to based on the MSC of SUA agreement send message before, earlier according to the address information of BSC/RNC itself, and the address information based on the MSC of SUA agreement that is belonged to carries out map addresses, finds out the SG address information of correspondence.

The address information mapping table based on the MSC of SUA agreement of finishing in this step that address information that the function of map addresses can be by the BSC/RNC itself that sets in advance and its belonged to is searched.

Step 202:BSC/RNC sends message to its pairing SG;

Carry OPC (the original signalling point of Original Point Code) information (promptly sending the BSC/RNC address information of this message), DPC information (the DPC information of this moment is the address information of purpose MSC) and SSN information in this message.

Because the embodiment of the invention is not changed traditional NO.7 signaling network, be the message of traditional NO.7 signaling network address format so BSC/RNC can only send OPC to its pairing SG.

The information that step 203:SG receives is carried out format conversion, and the SCCP message format is converted to the SUA message format.

SUA message after step 204:SG will change sends to MSC.

Step 205: described MSC receives this message, and handles accordingly.

For example, the address of supposing BSC/RNC is 1000, and the address of SG is 2000, and the address of MSC is 3000.BSC/RNC before sending message at first the address 1000 by self carry out map addresses with the MSC address 3000 of ownership, search in the BSC/RNC that stores to the system the data corresponding with the MSC address, finding out pairing SG address is 2000.Send to SG so and carry OPC=1000, DPC=3000, the message of SSN=MAP.

SG is the SUA form with the message conversion that receives, and is 3000 by the MSC address that receives, and this message is sent to MSC, and MSC handles accordingly according to the message of receiving.So far, just finished based on the SCCP signaling node to communication based on the network of SUA signaling node.

Receiving element is used to receive BSC/RNC sends address information of himself and the address information of its MSC that is belonged to;

Memory cell is used to store the address corresponding relation of BSC/RNC address, MSC address and SG;

Searching the unit is used for finding out the address information of the SG of correspondence with it by BSC/RNC address, MSC address to memory cell;

Transmitting element is used for after searching the unit and obtaining the SG address information this SG address being sent to BSC/RNC.

The SUA signaling node sends the embodiment 3 of message to the SCCP signaling node, referring to Fig. 7:

Step 301:MSC sends SUA message to core net SG.

Carry OPC (the original signalling point of Original Point Code) information (promptly sending the MSC address information of this message), DPC information (the DPC information of this moment is the address information of SG) and SSN information in this message.

Step 302: receive the SUA message of MSC transmission as SG after, by map addresses, find target node b SC/RNC address information based on SCCP according to the OPC message of carrying in the message (promptly sending the MSC address information of this message).

Map addresses function described in this step can by the OPC message (promptly sending the MSC address information of this message) that sets in advance with search based on the target node b SC/RNC address information mapping table of SCCP.

Step 303:SG is the target node b SC/RNC address information based on SCCP that finds with the DPC information change that carries in the information.

To more the correct one's mistakes message of DPC information of step 304:SG is carried out format conversion, is the SCCP message format that BSC/RNC needs with this message transformation, and sends to purpose BSC/RNC.

Step 305: described BSC/RNC receives this message, and handles accordingly.

For example, the address of supposing BSC/RNC is 1000, and the address of SG is 2000, and the address of MSC is 3000.MSC sends SUA message to core net SG, carries OPC=3000 in this message,, DPC=2000 and SSN=MAP.

After SG received this message, by map addresses, finding MSC was 1000 to the address of purpose BSC/RNC, and SG changes to 1000 with the DPC in the message, is the SCCP message format with this message conversion; To carry OPC=3000 again,, the message of DPC=1000 and SSN=MAP sends to MSC, MSC handles accordingly according to the message of receiving.So far, just finished based on the SUA signaling node to communication based on the network of SCCP signaling node.

Receiving element is used to receive the address information of the BSC/RNC that SG sends;

Memory cell is used for the purpose BSC/RNC address information corresponding relation of store M SC address information and its transmission message;

Searching the unit is used for finding out the purpose BSC/RNC address information that it sends message by MSC address information to memory cell;

The purpose BSC/RNC address information that the MSC that transmitting element is used for finding sends message feeds back to SG.

The SUA signaling node sends the embodiment 4 of message to the SCCP signaling node, referring to Fig. 8:

Step 401:MSC earlier according to the address information of MSC self, reaches the purpose BSC/RNC address information that sends message and carries out map addresses before purpose BSC/RNC sends message, finds out corresponding SG address information.

Finishing the function of map addresses in this step can search with the purpose BSC/RNC address information mapping table that sends message by the address information of the MSC self that sets in advance.

Step 402:MSC sends message to its pairing SG;

Carry OPC (the original signalling point of Original Point Code) information (promptly sending the MSC address information of this message), DPC information (the DPC information of this moment is the address information of BSC/RNC) and SSN information in this message.Because of find out corresponding SG address when step 401 after, MSC can determine to concrete SG transmission and not need the address of SG is carried in message.

Because the SUA agreement is supported the address format of various ways, so MSC sends to its pairing SG that to be not limited to the OPC address format in message be traditional NO.7 address format, can also be the IP address format.

Step 403:SG becomes the SCCP message format with this message conversion after receiving the message that MSC sends.

SCCP message after step 404:SG will change sends to BSC/RNC.

Step 405:BSC/RNC receives this message, and handles accordingly.

For example, the address of supposing BSC/RNC is 1000, and the address of SG is 2000, and the address of MSC is 3000.MSC at first carries out map addresses by the address 3000 of self and the purpose BSC/RNC address 1000 of message arrival before sending message, finding out pairing SG address is 2000.Send to SG so and carry OPC=3000, DPC=1000, the message of SSN=MAP.

SG is that 1000 message is carried out format conversion with the BSC/RNC address that receives, and the SUA message format is converted to the SCCP message format, again this message is sent to BSC/RNC, and BSC/RNC handles accordingly according to the message of receiving.So far, just finished based on the SUA signaling node to communication based on the network of SCCP signaling node.

Receiving element is used to receive the purpose BSC/RNC address information of the message of MSC sends the address information of himself and its transmission;

Search the unit, be used for finding out the address information of corresponding with it SG by BSC/RNC address, MSC address to memory cell;

Transmitting element is used for after searching the unit and obtaining the SG address information this SG address being sent to MSC;

The SUA of lower floor agreement sends the seamless intercommunication process of message to SCCP user, and following embodiment 5 is described:

Step 501:SUA node receives the SCCP message that contains the IP address format, and this IP address format is SCCP upper-layer user's address;

Step 502:SUA node call address mapping function obtains the DPC address format corresponding with this IP address format.

Finishing the map addresses function in this step can be undertaken by the IP address format of searching the SCCP upper-layer user who sets in advance, the mapping table of its corresponding DPC address format.

Step 503:SUA node changes to the address format that mapping finds with the address format in this message, and this message is sent to the SCCP upper-layer user.

Corresponding to this method, the embodiment of the invention also provides a kind of device of realizing service node and upper-layer user's intercommunication, and this device comprises: memory cell, search unit, receiving element, transmitting element;
