Abstract
The present invention relates to a method for solving load sharing between signaling link groups in a communication network. The preparation method comprises the following steps: a plurality of global codes and the use proportional relations thereof are configured in a local signaling office, and each global code is translated into different link groups in at least one configuration in the signaling office; according to the use proportional relations of the global codes, one global code is selected to be written in a calling address information field in a signaling message to be transmitted, and the signaling message is transmitted to at least one signaling office from the local signaling office; the signaling message is transmitted; the signaling message is received and processed by the signaling office; the signaling office writes the calling address information of the signaling message in a called address information field of a response message, and a link group obtained from selected global code addresses is transmitted back to the local signaling office. In the present invention, the load sharing of other signaling offices connected with the local signaling office is controlled by the configuration of the local signaling office, and the disadvantage of nonuniform load sharing of other signaling offices can be overcome.
Description
Technical field
The present invention relates to a kind of method that in communication network, solves load sharing between the signaling link group.
Background technology
The signaling of the Signaling System 7(SS-7) that defines at present domestic, the international standard connects control two kinds of addressing systems, and wherein a kind of is exactly the global title addressing.Global title in the network in the entity is a uniquely identified, in signaling office during according to the global title addressing with signaling connection control function, need carry out Global Title translation, find out the purpose signaling office that message sends by Global Title translation, signalling route, signaling link transmits signaling message on the signaling link that obtains then in Global Title translation, generally comprise the basis of global title as next stage signaling office Global Title translation in this signaling message.
In wireless network, the service traffics of signalling system No.7 roll up, and need carry out load sharing between the signaling link group.The mode that realizes load sharing can be to carry out load sharing in signalling route, also can share a plurality of signaling office when Global Title translation.But actual conditions are that the signaling office that moves in the network does not take into full account the load sharing problem owing to build early at present, does not support two load sharings between the above signaling link group.Signalling Transfer Point particularly, its traffic carrying capacity sharply increases, and does not solve the load sharing problem, just jeopardizes the safety of signaling network and stable.The signaling office of existing network operation is because traffic carrying capacity is big, if all upgraded version is to realize load sharing function, has risk and long time cycle.
With message between short message service center and the mobile switching centre is example, please refer to Fig. 1, and short message service center is connected with two Signalling Transfer Points, is transferred to mobile switching centre by two signal switchings signaling message of naming a person for a particular job.Be the relation of load sharing between two Signalling Transfer Points.If the signaling link way in the signaling link group of mobile switching centre's to two Signalling Transfer Point is inconsistent, between two Signalling Transfer Points, also to carry out load sharing during from mobile switching centre's return messages, if mobile switching centre does not support the load sharing in proportion between two signaling link groups, so just may make the load inequality of two link group.
Summary of the invention
The technical problem to be solved in the present invention provides the method that solves load sharing between the signaling link group in a kind of communication network, can control the load sharing ratio of other signaling offices to this signaling office.
In order to solve the problems of the technologies described above, the invention provides a kind of method that in communication network, solves load sharing between the signaling link group, it is applied to this signaling office by in a plurality of link group and the system that at least one signaling office links to each other, and it comprises the steps:
This signaling office disposes a plurality of global titles, and global title usage ratio relation, and in the configuration of this at least one signaling office with each Global Title translation to different link group;
According to the usage ratio of global title relation, a selected global title writes the calling address information field in the signaling message to be sent, sends to this at least one signaling office from this signaling office;
Transmit this signaling message; This at least one signaling office receives this signaling message and handles; This at least one signaling office writes the called address information field of response message with the calling address information of this signaling message, and goes back to this signaling office via the link group transmission that obtains from this selected global title addressing.
Compared with prior art, the present invention controls the load sharing ratio of other signaling offices to this signaling office by the configuration of this signaling office; Implementation is simple, and networking is more flexible; Switching equipment requirement to the existing network operation is low, does not need existing network equipment to carry out upgrading.Adopt the present invention, the load sharing problem between the signaling link group in the present signaling network can be effectively solved, and the load sharing (as the load sharing between 2Mbit/s high speed signaling group and the 64kbit/s signaling group) between different signaling link standards can be used to realize.To the networking mode of present existing 2Mbit/s high speed signaling link, also be a kind of effective compensation process.
