Embodiment
In 3G network of today is built, based on IP, transmission has become inevitable development trend, and has currently started to dispose such network.The embodiment of the present invention aims to provide a kind of scheme of effective selection service surface IP path, in order to reduce call loss, promotes percept of call completed.Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
When the invention process, upper and lower level equipment is for example all supported, on certain identical IP path detection technique: ICMP or BFD, provide the selection scheme of service surface IP address on this basis.Set forth its application scheme for subordinate equipment and higher level equipment respectively below.
In enforcement, higher level equipment refers to: in selection IP path process, and the communication equipment of preferential selecting business face IP address; Subordinate equipment refers to: in selection IP path process, select the communication equipment of the IP address matching with the service surface IP address of higher level equipment appointment.
One, the enforcement of subordinate equipment.
Fig. 1 is the system of selection implementing procedure schematic diagram of downlink device service IP address, and as shown in the figure, subordinate equipment, in the IP address process of selecting the service surface IP address of specifying with higher level equipment to match, can comprise:
Step 101, higher level equipment are that subordinate equipment is specified certain service surface IP address;
Step 102, subordinate equipment utilize IP path detection technique to select the IP address that can be communicated with;
Service surface IP address or reply that step 103, subordinate equipment superior device replied are selected are selected unsuccessfully.
In enforcement, as subordinate equipment, realize fairly simple, because first higher level equipment has specified the IP address of service surface, whether the service surface IP address that subordinate equipment is specified for higher level equipment, utilizing IP path detection technique to survey one by one each service surface IP of this equipment can be coupled logical just passable.If there is the service surface IP address that can be communicated with, just can respond to higher level equipment, connect thereby set up service surface; If all IP of subordinate equipment have surveyed address and have not also found the IP address that can be communicated with, to higher level equipment response failed message, further, can also prompting office side attendant check whether data configuration has problems, or whether transmission is out of joint.
In concrete enforcement, for subordinate equipment, owing to having known the selected IP of higher level equipment address, so select the IP that can be communicated with when subordinate equipment is selected IP address.If there are multiple IP addresses that can be communicated with, in enforcement, can select according to the principle of load balancing (using bandwidth occupancy is foundation).
Reply to the response message of higher level equipment for subordinate equipment, reply can be according to Bureau of Standards's interface message of having reserved in agreement (as NodeB replies to the wireless link response message of RNC, the RAB that RNC replies to CN assigns response message), in the time replying failure response message, although carry error reason in intercarrier interface message, this error reason can not accurately inform it is obstructed the causing in service surface IP address.So in further implementing, subordinate equipment can also report an event or alarm to webmaster, this is also conducive to the rapid troubleshooting of network O&M personnel, reduces the loss therefore causing, and reduces network operation cost.
Two, the enforcement of higher level equipment.
Inventor notices in invention process: as higher level equipment, though be that local terminal is preferentially selected service surface IP address, if local terminal chooses at random service surface IP address, want merely to select by subordinate equipment the words of corresponding IP address, also can have problems, reason has two at least:
The one, although subordinate equipment supports IP path to detect, but do not apply, for example generally all can support ICMP, but not necessarily be used for carrying out detection and the selection of service surface IP connectivity, the IP address that the IP address that now subordinate equipment is selected may not be selected with higher level equipment is connected.
The 2nd, even if subordinate equipment also has the mechanism of utilizing IP path detection technique to select service surface IP address, if but the IP address that higher level equipment is selected is improper, or intermediate conveyor goes wrong, may cause the service surface IP address of selecting for higher level equipment, subordinate equipment cannot be selected the IP address being connected, and like this also can cause call loss.
Given this, for higher level equipment, after subordinate equipment is selected corresponding service surface IP address, if higher level equipment carries out the detection of IP path, and connectedness is added up, just can in the time of follow-up selection local terminal service surface IP address, analyze, determine the selection probability of local terminal each service surface IP address.Further, just can, by this probability for reducing call loss, promote percept of call completed.
But, compare subordinate equipment, the realization of higher level equipment is also therefore more more complex.Concrete, it is realized and roughly can comprise 2 points:
One,, for certain service surface IP address of local terminal, if there is the selected service surface IP of subordinate equipment address and its situation that cannot be communicated with, reduce the selection probability of this service surface IP address;
If two for certain service surface IP address of local terminal, unborn unconnectedness situation is eliminated, and recovers the selection probability of its IP address;
Accomplish above two a little, can not depend merely on a detection of connectivity result judges, need to add up connective result, statistical information can comprise that IP address, to information such as, IP address choice total degree, disconnected number of times, then analyzes and make decision on this statistical information basis.Fig. 2 is the statistical information schematic diagram for a service surface IP address of higher level equipment, analyzes that make decision can be as shown in the figure on statistical information basis.
Below in fact executing and describe.
Fig. 3 is the system of selection implementing procedure schematic diagram of service surface IP address, and as shown in the figure, higher level equipment can comprise the steps: in the time selecting
Step 301, higher level equipment are subordinate equipment specified services face IP address;
Step 302, higher level equipment form the connection probability of service surface IP path according to connectedness response statistics this service surface IP address of subordinate equipment;
Step 303, higher level equipment, being in the process of subordinate equipment specified services face IP address, are specified according to the connection probability of each service surface IP address formation service surface IP path.
, in conjunction with the consideration of first and second point, in concrete enforcement, can also process as follows:
1, higher level equipment being in the process of subordinate equipment specified services face IP address, in the time that the connection probability that forms service surface IP path according to each service surface IP address is specified, can comprise one of following mode or its combination:
1), reduce and specify the connection low service surface IP address of probability.
2), obtaining after the connection probability of service surface IP, determine whether to specify this service surface IP address according to the new connection probability obtaining in this service surface IP address.
3), determine that according to the call loss scope allowing statistics is communicated with probability required total degree, reaching after this total degree, determining whether to specify this service surface IP address according to the connection probability of this service surface IP address.
4), be communicated with probability be 1 o'clock, send warning.
In enforcement, can be when higher level equipment find subordinate equipment selected service surface IP address and self selected service surface IP address obstructed after, first upgrade statistical information, for example: corresponding IP address is increased progressively not being communicated with number of times, then it reduces the selection probability for this service surface IP address, even if can be communicated with for other IP address of subordinate equipment.
May be required in principle and carry out selecting probability adjustment after a certain amount of calling again, as 200 times, its object is to ensure that " not being communicated with the total selection number of times in number of times/this IP address " is within allowed call loss scope.
If higher level equipment selects other service surface IP address also always to have disconnected situation, finally cannot ensure that call completing rate requires time, can also send alarm, prompting office side webmaster personnel to analyzing, are where out of joint to determine to disconnected IP address.
2, can further include:
1), get rid of after the fault that forms service surface IP path, for required connection probability is specified in this service surface IP address assignment.
2), get rid of after the fault that forms service surface IP path, delete the statistical information of this service surface IP address.
3), higher level equipment is while determining that according to the connectedness response of subordinate equipment this subordinate equipment selects the number of times of this service surface IP address to reach threshold value, deletes the statistical information of this service surface IP address.
In enforcement, for example, if cause disconnected problem reparation: one party correction configuration data, or intermediate conveyor fault recovery, higher level equipment also needs to recover the selection probability of corresponding service face IP address, to ensure that load evenly.
If higher level equipment correction configuration data, deletes or revised certain service surface IP, its corresponding connective statistical information is directly deleted;
If subordinate equipment correction configuration data (higher level equipment cannot be learnt), higher level equipment can after subordinate equipment has had several times no longer to select certain service surface IP address be deleted its statistical information finding;
If intermediate conveyor fault recovery, if higher level equipment finds originally to exist disconnected IP address to being again communicated with, directly by its corresponding statistical information clear 0.
Based on same inventive concept, the selection equipment of a kind of service surface IP address is also provided in the embodiment of the present invention, because the principle that this equipment is dealt with problems is similar to the system of selection of a kind of service surface IP address, therefore the enforcement of this equipment can be referring to the enforcement of method, repeats part and repeat no more.
