Embodiment
Reach technological means and the effect that predetermined purpose is taked for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, the method and system of issuing page message in Ethernet to the present invention proposes is described in detail as follows.
In the first embodiment of the invention, a kind of in Ethernet the method for issuing page message, as shown in Figure 3, comprise the steps:
Step 1, in network, dispose the paging node, because the deployment of base station is very flexible in network, so the paging node also needs to dispose according to the deployment scenario of base station, with paging node access network based on ethernet and the base station can directly be had access to, when described Ethernet is the Internet, the paging node must have independently internet-ip address, preferably, can dispose the paging node in the router side in the network equipment, the network equipment can also comprise hub and/or switch except router, base station controller is preserved the paging node listing.Because the processing logic of paging node is relatively simple, hardware interface is single, usually adopt Ethernet interface, therefore the high network processing unit of Ethernet message treatment effeciency is adopted in suggestion, and common computer, server or embedded device etc. also can be competent at certainly.
Step 2, between base station controller and paging node, set up communication link, select paging node that base station controller need to use and it is carried out configuration of data and synchronously.The method of the paging node that described selection base station controller need to use is, the keeper is according to what of the deployment scenario of paging node and the available paging resource of residue, and the lane place of base station controller configuration carries out static state and selects, and selects apart from the lane place of its configuration closely as far as possible and remain the more paging node of available paging resource.Remaining whole paging resources that available paging resource refers to the paging node deducts after the part of being used by other base station controllers configurations, remaining paging resource, can support the paging of 100 base stations such as certain paging node, first base station controller has disposed 40 base stations in the above, the paging capability that to remain so available paging resource be exactly 100-40=60 base station.Certainly base station controller selects the mode of paging node also can automatically select according to certain rule.
Described data configuration comprises lane place, the station list in the lane place and the tabulation of base station network address information that every paging node need to manage, and described base station network address information tabulation comprises the IP address of base station and port etc.The access bandwidth of every paging node has determined maximum position district number and the maximum total number of base that it can dispose, and they have formed the paging resource of this paging node jointly, has embodied the maximum beep-page message distribution capability of this paging node.Base station controller can be shared the paging resource of paging node, namely do not exceed at the paging resource limitation that does not exceed the paging node in the situation of maximum beep-page message distribution capability of paging node, the paging node can receive the beep-page message distributed tasks from a plurality of different base station controllers, therefore, the paging node is not under the jurisdiction of any one base station controller, be that base station in the lane place of its service can be from a plurality of office, office refers to a base station controller and all base stations of administering thereof.
A paging node can dispose a plurality of lane place, lane place can separate configuration on a plurality of paging nodes, described data can change when the base station is accessed or withdrawed from, and need base station controller in time the data after the change to be synchronized to corresponding paging node by communication link.
Communication link agreement between paging node and the base station controller can flexible choice, can be TCP (Transfer Control Protocol, transmission control protocol) or the connection-oriented link protocol such as RUDP (Reliable User DatagramProtocol, RUDP).If adopt TCP, then its link setup and maintenance all are the ICP/IP protocol of standard, if adopt RUDP, then are link setup and the maintenance mechanisms that uses himself, and this is the technological means that those skilled in the art commonly use, so locate not describe in detail.
Step 3, for the situation of base station from the Internet access, base station controller sends message to the base station, notifies its corresponding paging node, if restart the base station, base station controller needs again to send message to this base station and notify.Each base station also needs periodically to send activation message to its corresponding paging node, the transmission time interval that activates message need to be less than UDP (User Datagram Protocol, User Datagram Protoco (UDP)) NAT (Network Address Translator, network address translation) list item ageing time, this activation message is short and small and do not need to respond, only pass through for the NAT of paging node to downstream IP message between the base station, passing through principle is the known technology of this area, so locate not describe in detail;
Situation for base station access enterprise network, because the paging node does not need the gateway through NAT to the IP message between the base station, base station controller need not to notify its corresponding paging node, each base station also need not periodically to send activation message to its corresponding paging node simultaneously, therefore, in this case, can omit step 3.
Above-mentioned steps one, two, three was actually before the beep-page message of core net initiation to the terminal called user, the preparation of doing for issuing page message in Ethernet, but wherein, base station controller carries out the whole process that data then are in Ethernet issuing page message synchronously to its paging node that need to use, in case the situation of base station access network network changes, in time the data after the change are synchronized to corresponding paging node with regard to needing base station controller by communication link.
Step 4, when core net is initiated beep-page message to the terminal called user, after base station controller receives beep-page message to the terminal called user from core net, according to the location area information in the described beep-page message, only send a described beep-page message to the paging node that has disposed this lane place, if this lane place separate configuration is on a plurality of paging nodes, then base station controller need to send described beep-page message to described a plurality of paging nodes.In the art, core net, base station controller etc. can be referred to as wireless device, and router, switch and hub etc. can be referred to as the network equipment.
Step 5, paging node copy described beep-page message and recombinate and generate the IP message, and send to the base station in relevant position district, particularly, the paging node is behind the ethernet frame of the beep-page message that the As-received station control is sent, solution contracts out effective payload, effectively payload refers to the base station controller that comprises in the IP message and will issue beep-page message content on the application of base station, namely removed the live part of Ethernet frame head, IP head and connection protocol head, if what use is udp protocol, what effectively payload referred to is exactly the live part that has removed the UDP head.Again take effective payload as basis restructuring IP message, the agreement that the IP message of restructuring uses needs only the base station and can identify, can use the non-connectionless protocol that retransmits according to the order of sequence, RUDP's without frame number frame type, UDP or RTP (Real-time Transport Protocol, RTP) etc. for example.Then be copied into many parts of IP messages according to the base station number in the lane place of this paging node configuration, next rewrite the described IP message that copies according to IP address and the port numbers of purpose base station in the tabulation of base station network address information, obtain the IP message that can issue, the IP message that can issue at last sends to the network equipment by network, by the network equipment this IP message is sent to the base station.Finish thus the whole process of issuing page message in Ethernet.
The below is take a small-sized enterprise network that comprises a stylobate station control as example, the implementation procedure of the method for issuing page message in Ethernet is described described in the first embodiment of the invention, as shown in Figure 1, base station controller c is by the 3rd enterprise network router d3 access enterprise network.Base station controller c has disposed A, B, three lane place of C, comprise an A district base station A1 and the 2nd A district base station A2 in the A lane place, comprise a B district base station B1, the 2nd B district base station B2, the 3rd B district base station B3 and the 4th B district base station B4 in the B lane place, comprise a C district base station C1, the 2nd C district base station C2, the 3rd C district base station C3 and the 4th C district base station C4 in the C lane place.Enterprise network is accessed by hub or switch in the base station: the base station in the A lane place is by the first hub J1 access enterprise network, base station in the B lane place is by the second hub J2 access enterprise network, C district base station C1 in the C lane place, the 2nd C district base station C2 are by the 3rd hub J3 access enterprise network, and the 3rd C district base station C3, the 4th C district base station C4 are by the 4th hub J4 access enterprise network.Four paging nodes have been disposed on enterprise network router side: at other the 7th paging node 7, the 8th paging node 8 and the 9th paging node 9 disposed simultaneously of the first enterprise network router d1, at other the tenth paging node 10 of disposing of the second enterprise network router d2.Because the access bandwidth of base station in enterprise network be much larger than the access bandwidth in the Internet, and enterprise's innings number and scale of required deployment when reality is used be with the base station number all than the Internet much less, so only need dispose a small amount of paging node.
Base station controller c is according to the lane place of its configuration and paging resource utilization and the deployment scenario of paging node, select the 7th paging node 7, the 8th paging node 8 respectively as the paging node of A lane place and B lane place, the 9th paging node 9 and the tenth paging node 10 common paging nodes as the C lane place, particularly, the 9th paging node 9 is responsible for a C district base station C1, base station, the 2nd C district C2 distributing seeking message, and the tenth paging node 10 is responsible for the 3rd C district base station C3, base station, the 4th C district C4 distributing seeking message.
When core net is initiated beep-page message to the terminal called user to the B lane place, after base station controller c receives beep-page message to the terminal called user from core net, according to the location area information in the described beep-page message, only send a beep-page message to the 8th paging node 8, the 8th paging node 8 copies four parts according to the base station number that disposes in its administration lane place with the beep-page message of receiving, according to the network address information in the tabulation of base station network address information described beep-page message is reformulated the IP message again, be transmitted to respectively the B district base station B1 in the B lane place, the 2nd B district base station B2, the 3rd B district base station B3 and the 4th B district base station B4;
When core net is initiated beep-page message to the terminal called user to the C lane place, base station controller c respectively sends a beep-page message to the 9th paging node 9 and the tenth paging node 10, the 9th paging node 9 copies two parts according to the base station number that disposes in its administration lane place with the beep-page message of receiving, according to the network address information in the tabulation of base station network address information described beep-page message is reformulated the IP message again, be transmitted to respectively a C district base station C1, the 2nd C district base station C2, the tenth paging node 10 also copies two parts according to the base station number that disposes in its administration lane place with the beep-page message of receiving, according to the network address information in the tabulation of base station network address information described beep-page message is reformulated the IP message again, be transmitted to respectively the 3rd C district base station C3, the 4th C district base station C4.
In the second embodiment of the invention, a kind of in Ethernet the method for issuing page message, comprise the steps:
Step 1, in network, dispose the paging node, because the deployment of base station is very flexible in network, so the paging node also needs to dispose according to the deployment scenario of base station, with paging node access network based on ethernet and the base station can directly be had access to, when described Ethernet is the Internet, the paging node must have independently internet-ip address, preferably, can dispose the paging node in the router side in the network equipment, the network equipment can also comprise hub and/or switch except router, base station controller is preserved the paging node listing.Because the processing logic of paging node is relatively simple, hardware interface is single, usually adopt Ethernet interface, therefore the high network processing unit of Ethernet message treatment effeciency is adopted in suggestion, and common computer, server or embedded device etc. also can be competent at certainly.
Step 2, between base station controller and paging node, set up communication link, select paging node that base station controller need to use and it is carried out configuration of data and synchronously.The method of the paging node that described selection base station controller need to use is, the keeper is according to what of the deployment scenario of paging node and the available paging resource of residue, and the static state selection is carried out in the lane place of base station controller configuration, select near apart from the lane place of its configuration as far as possible and remain the more paging node of available paging resource, selected paging node specifically is divided into two classes: primary paging node and backup paging node, determined by base station controller that and be used as primary paging node or backup paging node base station controller can be that selected any one primary paging node is specified paging node for subsequent use.
Described data configuration comprises lane place, the station list in the lane place and the tabulation of base station network address information that every paging node need to manage, and described base station network address information tabulation comprises the IP address of base station and port etc.A paging node can dispose a plurality of lane place, lane place can separate configuration on a plurality of paging nodes, but does not repeat the base station that primary paging node disposes each other.Described data can change when the base station is accessed or withdrawed from, and need base station controller in time the data after the change to be synchronized to corresponding paging node by communication link.The access bandwidth of every paging node has determined maximum position district number and the maximum total number of base that it can dispose, and they have formed the paging resource of this paging node jointly, has embodied the maximum beep-page message distribution capability of this paging node.Base station controller can be shared the paging resource of paging node, namely do not exceed at the paging resource limitation that does not exceed the paging node in the situation of maximum beep-page message distribution capability of paging node, the paging node can receive the beep-page message distributed tasks from a plurality of different base station controllers, therefore, the paging node is not under the jurisdiction of any one base station controller, be that base station in the lane place of its service can be from a plurality of office, office refers to a base station controller and all base stations of administering thereof.
Communication link agreement between paging node and the base station controller can flexible choice, can be the connection-oriented link protocols such as TCP or RUDP.If adopt TCP, then its link setup and maintenance all are the ICP/IP protocol of standard, if adopt RUDP, then are link setup and the maintenance mechanisms that uses himself, and this is the technological means that those skilled in the art commonly use, so locate not describe in detail.
The backup paging node plays the effect of beep-page message distribution backup to primary paging node.It is synchronous that base station controller all carries out data configuration and data by communication link to primary paging node and backup paging node, and configuration and synchronous data that primary paging node and the backup paging node corresponding with it are received are identical.Difference is, when the beep-page message to the terminal called user issues, only have the described beep-page message that primary paging node can the As-received station control sends and copy and distribute, the backup paging node just can't be received described beep-page message as the backup of primary paging node after having carried out data configuration.And when the communication link between base station controller and the primary paging node interrupted, it is primary that base station controller can transfer corresponding backup paging node to, continues to finish the distribution function to described beep-page message.Backup mode can carry out flexible configuration according to the paging resource situation, when more such as the paging node, can also select multi-level backup.
Step 3, for the situation of base station accessing Internet, base station controller sends message to the base station, notifies the primary and backup paging node of its correspondence, if restart the base station, base station controller needs again to send message to this base station and notify.Each base station also needs periodically to send activation message to its corresponding paging node, the transmission time interval that activates message need to be less than the NAT list item ageing time of UDP, this activation message is short and small and do not need to respond, only pass through for the NAT of paging node to downstream IP message between the base station, passing through principle is the known technology of this area, so locate not describe in detail;
Situation for base station access enterprise network, because the paging node does not need the gateway through NAT to the IP message between the base station, base station controller need not to notify its corresponding paging node, and each base station also need not periodically to send activation message to its corresponding paging node simultaneously.
Above-mentioned steps one, two, three was actually before the beep-page message of core net initiation to the terminal called user, the preparation of doing for issuing page message in Ethernet, but wherein, base station controller carries out the whole process that data then are in Ethernet issuing page message synchronously to its paging node that need to use, in case the situation of base station access network network changes, in time the data after the change are synchronized to corresponding paging node with regard to needing base station controller by communication link.
Step 4, when core net is initiated beep-page message to the terminal called user, after base station controller receives beep-page message to the terminal called user from core net, according to the location area information in the described beep-page message, only send a described beep-page message to the primary paging node that has disposed this lane place, if this lane place separate configuration is on a plurality of primary paging nodes, then base station controller need to send described beep-page message to described a plurality of primary paging nodes.
Step 5, primary paging node copy described beep-page message and recombinate and generate the IP message, and send to the base station in relevant position district, particularly, primary paging node is behind the ethernet frame of the beep-page message that the As-received station control is sent, solution contracts out effective payload, effectively payload refers to the base station controller that comprises in the IP message and will issue beep-page message content on the application of base station, namely removed the live part of Ethernet frame head, IP head and connection protocol head, if what use is udp protocol, what effectively payload referred to is exactly the live part that has removed the UDP head.Take effective payload as basis restructuring IP message, the agreement that the IP message of restructuring uses can be used the non-according to the order of sequence connectionless protocol of re-transmission as long as the base station can be identified again, such as RUDP without frame number frame type, UDP or RTP etc.Then be copied into many parts of IP messages according to the base station number in the lane place of this primary paging node configuration, next rewrite the described IP message that copies according to IP address and the port numbers of purpose base station in the tabulation of base station network address information, obtain the IP message that can issue, the IP message that can issue at last sends to the network equipment by network, by the network equipment this IP message is sent to the base station.Finish thus the whole process of issuing page message in Ethernet.

Core net is used for the beep-page message to the terminal called user of initiating;
Base station controller is used for preserving the paging node listing, and the paging node that needs are used carries out the configuration of data with synchronously, and when described Ethernet was the Internet, described base station controller also was used for its corresponding paging node of informing base station; When receive that core net initiates to terminal called user's beep-page message the time, also be used for sending beep-page message according to the location area information of described beep-page message to the paging node that has disposed this lane place.Described data configuration comprises lane place, the station list in the lane place and the tabulation of base station network address information that every paging node need to manage, and described base station network address information tabulation comprises the IP address of base station and port etc.A paging node can dispose a plurality of lane place, lane place can separate configuration on a plurality of paging nodes, but does not repeat the base station that primary paging node disposes each other.Described data can change when the base station is accessed or withdrawed from, and need base station controller in time the data after the change to be synchronized to corresponding paging node by described communication link.
The paging node generates the IP message for the beep-page message of receiving being copied and recombinating, and sends to the network equipment.Particularly, the beep-page message distribution module is behind the ethernet frame of the beep-page message that the As-received station control is sent, solution contracts out effective payload, effectively payload refers to the base station controller that comprises in the IP message and will issue beep-page message content on the application of base station, has namely removed the live part of Ethernet frame head, IP head and connection protocol head.Take effective payload as basis restructuring IP message, the agreement that the IP message of restructuring uses can be used the non-according to the order of sequence connectionless protocol of re-transmission as long as the base station can be identified again, such as RUDP without frame number frame type, UDP or RTP etc.Then be copied into many parts of IP messages according to the base station number in the lane place of this paging node configuration, next rewrite the described IP message that copies according to IP address and the port numbers of purpose base station in the tabulation of base station network address information, obtain the IP message that can issue, the IP message that can issue at last sends to the network equipment by network.
The paging node specifically can be divided into two classes: primary paging node and backup paging node, backup paging node play the effect of beep-page message distribution backup to primary paging node.Base station controller can be shared the paging resource of paging node, namely do not exceed at the paging resource limitation that does not exceed the paging node in the situation of maximum beep-page message distribution capability of paging node, the paging node can receive the beep-page message distributed tasks from a plurality of different base station controllers, therefore, the paging node is not under the jurisdiction of any one base station controller, be that base station in the lane place of its service can be from a plurality of office, office refers to a base station controller and all base stations of administering thereof.
The network equipment, the IP message repeating that is used for the paging node is sent is to the base station.
The whole process of issuing page message in Ethernet by wireless mouthful of paging terminal called user, is finished thus in the base station.When described Ethernet was the Internet, described base station also was used for periodicity to the paging node transmission activation message of correspondence.
Of the present invention in Ethernet the method and system of issuing page message, copying, recombinating and sending to be placed in the paging node that is independent of base station controller and finish beep-page message, taking Abis mouth resource when greatly having saved the base station controller issuing page message, effectively solved because the series of problems that the base station controller Abis mouth beep-page message flow that the number of base stations surge causes expands and causes, greatly improve access capability and the Abis mouth efficient utilization of resource rate of base station controller Abis mouth, can support more base station under the comparable bandwidths.In addition, issue owing to adopt the paging node specially beep-page message to be processed, avoided the forwarding by intermediate link in the network, guaranteed the reliability that beep-page message sends.
Take the gigabit bandwidth as example, do not consider data service if only consider voice service, the Abis mouth has the ability of the IP femto base station of 50000 family expenses patterns of access at least so.Because the paging resource of paging node is shared, and base station controller does not need to be separately the special-purpose paging node of part administration of self, shared mode is conducive to save the paging resource of paging node again.Moreover, base station controller in the second embodiment of the invention can select to realize backup at the paging node, when breaking down, communication link can automatically adjust quickly and easily, improved the robustness of beep-page message distribution function, robustness refers to that the ability of normal operation occurs can continue to keep fault.At last, because the processing logic of paging node is relatively simple, hardware interface is single, can select common computer, server or embedded device etc., so the adding of paging node can't increase the cost of networking, and it is convenient to dispose quite flexible, therefore disposes in advance the paging node according to the covering scale, will become the equipment supplier and answer the effective sharp weapon of target.
