The utility model discloses an detection method for detecting the abnormal network nodes. The method arranges the link status zone bit in the communication program; as the communication program starts up, the examination thread is established to examine each link in the link information table, so as to check for the network nodes which are correspondent to the link. If the link status zone bit thereof is under running state and the difference between the present time and the link's message sending time is no less than the pre-set value, the link's correspondent network nodes are judged as abnormal. So, the link shall be closed and informed to the upper level; or, the next link shall be examined. The utility model can conduct the judgment before receiving the other side's heart-beat messages or recv function return or send function return, so as to greatly shorten the testing time used for detecting the abnormal conditions of the network nodes. Also, the call loss is reduced.

The calling method comprises the following steps of: transmitting a state query request to a home location register (HLR) before a called terminal initiates a call, wherein the state query request carries the number of the called terminal; and determining whether to initiate a calling request to the called terminal according to the received current state information of the called terminal returned by the HLR. Meanwhile, the embodiment of the invention also provides calling equipment and a calling system. In the embodiment of the invention, by acquiring the state of a user to be called before calling and determining whether to initiate the calling to the user to be called according to the state of the user to be called, the waste of network resources is avoided, the network call loss is reduced, and the working efficiency is improved.

A method for allocating resources in a communication system. The applicable communication system includes equipment such as a main processing board, a call processing board, and a resource single board. The call processing board establishes an ordered list according to the resource boards and processing capabilities in the group; when the system receives a service resource application, the main processing board initiates a resource application request to a device group; Select a board in the group, select a board with sufficient processing capacity, and send a resource application to the resource board; if there is no such board in the group, send a resource request message to the next device group, and the next device group will process it . According to the principle of selecting resource boards in a round-robin group, the present invention performs resource allocation in combination with resource processing capabilities, thereby realizing load sharing and increasing a hit rate. Using distributed database management, the structure is clear and the interaction is simple. Resource application is separated from service process, effectively using resources and reducing call loss.

The invention discloses a method for improving the reliability of location update in a wireless local telephone system. The core idea is to save the information of the user's previous call area on the HLR, and set a state machine on the HLR to identify each state in the location update process. According to the judgment of the message reported by the BSC, the state transition and corresponding processing are carried out. When the call area information error caused by the incomplete location update process, the HLR will actively initiate the location confirmation process to the user. By adopting the method of the present invention, the reliability of the location update process in the wireless local telephone system is improved, the problem of wrong calling area information caused by message loss is largely avoided, and the call loss when called is reduced. It improves the call rate of the whole system and the satisfaction of users, and at the same time reduces the workload of system maintenance personnel.

The invention discloses a charging processing method, comprising the following steps: when a charging processing of a conversion has abnormal changes, an OCS receives the calling record generated by an external network element, which includes the label of the conversion; and re-charging is carried out on the conversion according to the label in the calling record. The invention also discloses a charging processing system and the on-line charging system OSC. In the embodiment of the invention, a calling record is generated only for conversion having abnormal changes, in no need of generating CDR for all conversions, thus saving the processing resources of the external network element and saving disk space for storing the CDS; since the OCS can re-charge for the conversion having abnormal changes, the loss caused by directly drawback of deducted fee and reserved fee is reduced, thus realizing precise charging when a conversion has abnormal changes.

The invention relates to a method to select an application-layer controllable No. 7 signaling dynamic route, a network-layer uses a route table to dynamically select an available signaling route, the method also includes that the application-layer sends request information to the network-layer; the network-layer feeds back to the application-layer the route selecting result which corresponds to the request information; the application-layer adjusts the route table according to the route selecting result and the content of the route table. The method, based on the prior protocol, feeds back the route selecting result to the application-layer through the network-layer, the application-layer does not change the selecting way of the prior route and just decides whether the dynamic route selecting range is adjusted according to the information processing condition, thereby realizing the method to select the application-layer controlled No. 7 signaling dynamic route. The method solves the problem that the application-layer can directly adjust the selection-awaited No.7 signaling route when the information route is not successful or can not meet the requirement of the application-layer, and reduce the unnecessary call loss; the method is the beneficial supplement and perfection of the prior signaling route.

The resolution method under framework with separated signaling and business comprises: when SS7UP receives another IAM while sending IAM and waiting for BCM response, drops if master control or buffers if not, and indicates BCM to generate outside contend together; after reselecting path, SS7UP processes buffered IAM; when receives SetupInd before BCM sends SetupInd or after sending SetupInd, drops if master control, or reselects for calling if not main control and BCM has sent SetupInd, or records it as having content together, and checks the record after process to reselect for calling if having content. This invention can reduce calling loss when there is much telephone communication.

The invention discloses a method for improving the success rate of call connection. The method includes the following steps: A. After the access device detects that the user is off-hook, it sends a dial tone to the user, and adopts the number collection strategy currently stored by itself to receive the number. B. When the softswitch releases the call, it sends the next number collection strategy to the access device, and the access device stores the received number collection strategy. In the method provided by the present invention, the method of issuing the number receiving strategy in the process of establishing a call is changed to issuing the number receiving strategy in the process of releasing the call. Through the improvement of this method, the call loss of the user during the call process is reduced, and the success rate of the connection is improved, especially in a network environment with poor network quality, the effect is particularly obvious.

The invention discloses an information reporting method based on a gateway resource group, which is used in a packet network including a media gateway and a media gateway controller, comprising the following steps: dividing resources connected by the media gateway into multiple resource groups, The media gateway sends the attribute information of each resource group to the media gateway controller; after receiving the attribute information of the resource group, the media gateway controller takes different processing according to the attribute characteristics of different resource groups. The method of the invention introduces the granularity of the resource group on the MG and the MGC, effectively reducing the call loss to the whole resource adjustment caused by partial resource congestion.
