Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method and a network element for sending a call signaling.
Background
In IMS, a failure occurs during a call by a user. IMS is an abbreviation for IP multimedia Subsystem (IPMultimedia Subsystem), and IP is an abbreviation for Internet Protocol (Internet Protocol). In order to locate a fault in a user's call process, a user's tracking task needs to be created on a network element through which the user's call signaling will pass, so that the user's call signaling sends a tracking result to the network management device when passing through the network element.
In an IMS network, there are many network elements. The number of network elements typically varies from a few to hundreds, depending on the size of the network. Since it is not known which network element the call signaling of the user will pass through, the network management system will send the tracking task of the user to all network elements, and then all network elements will create the tracking task of the user. When the network element receives a call request of any user, the network element will inquire whether the tracking task corresponding to the user exists in all the tracking tasks, and if so, the network element sends a call signaling of the user to the network management system. The method for creating the tracking task can create a large number of tracking tasks of the users which do not send the call signaling to the network element on the network element, so that when the network element receives the call signaling of the users, whether the tracking tasks of the users exist or not needs to be judged from the large number of tracking tasks, and then whether the call signaling of the users is sent to a network management system or not is determined, and the resource utilization rate and the tracking efficiency of the network element are reduced.
In the prior art, in order to reduce the number of tracking tasks that a network element needs to query when receiving a call signaling of a user, a network management system queries and determines which network element the user registers before sending the tracking task of the user to the network element, and then sends the tracking task to the network element. And after receiving the tracking task sent by the network management system, the network element creates the tracking task. The method ensures that the tracking task of the user cannot be created on the network element which is not registered by the user, thereby reducing the quantity of the tracking task which needs to be inquired.
However, in the IMS network, when a user may re-register to another network element for some reason (for example, the user equipment is powered off and then powered on again), and the network element where the user re-registers does not create a tracking task for the user, the tracking of the call signaling of the user cannot be completed, that is, the call signaling of the user cannot be sent to the network management equipment.
Disclosure of Invention
The invention provides a method for sending a call signaling and a network element, which can improve the resource utilization rate of the network element and the tracking efficiency of the call signaling.
In a first aspect, a method for sending call signaling is provided, including: a network element receives at least one tracking task sent by a network management system, wherein each tracking task comprises a user identification number corresponding to the tracking task; the network element adds at least one tracking task comprising the user identification number of the user successfully registered on the network element to a tracking task set; a network element receives a call signaling carrying a user identification number; the network element determines that a tracking task comprising a user identification number carried by a call signaling exists in a tracking task set; and the network element sends the call signaling to a network management system.
In the method for sending the call signaling, when the network element determines that the tracking task comprising the user identification number of the user successfully registered on the network element exists in at least one tracking task received by the network management system, the tracking task is added into a tracking task set. Therefore, when the network element receives the call signaling, the call signaling can be sent to the network management system to complete the tracking task only by inquiring the tracking task comprising the user identification number carried in the call signaling from the tracking task set. The technical method not only prevents the network element from creating the tracking task of the call signaling which does not pass through the user of the network element, but also ensures that the network element can create the tracking task of the call signaling which passes through the user of the network element, and finally improves the resource utilization rate of the network element and the tracking efficiency of the call signaling of the user.
With reference to the first aspect, in a first possible implementation manner, adding, by a network element, a tracking task, in which at least one tracking task includes a user identification number of a user successfully registered on the network element, to a tracking task set, includes: the network element determines a first tracking task from at least one tracking task; the network element determines that the user identified by the user identification number included in the first tracking task is successfully registered on the network element; the network element adds the first tracking task to the set of tracking tasks.
In the method for sending the call signaling, when the network element judges that a user corresponding to a certain tracking task in at least one tracking task sent by a network management system and received by the network element is a user successfully registered on the network element, the tracking task is added into a tracking task set. Therefore, when the network element receives the call signaling of the user, the network element only needs to inquire the tracking task of the call signaling of the user from the tracking task set, and then the call signaling of the user can be sent to the network management system to complete the tracking task. The technical method not only prevents the network element from creating the tracking task of the user of which the call signaling does not pass through the network element, but also ensures that the network element can create the tracking task of the user of which the call signaling passes through the network element, and finally improves the resource utilization rate of the network element and the tracking efficiency of the call signaling of the user.
With reference to the first aspect, in a second possible implementation manner, adding, by a network element, a tracking task, in which at least one tracking task includes a user identification number of a user successfully registered on the network element, to a tracking task set, includes: a network element receives a registration request message carrying a first user identification number; then, according to the registration request message, the successful registration of the user identified by the first user identification number on the network element is determined; then determining that a tracking task comprising a first user identification number exists in at least one tracking task; and finally, adding the tracking task of which at least one tracking task comprises the first user identification number into the tracking task set.
The method for sending the call signaling comprises the steps that the network element judges that a certain user is successfully registered on the network element, judges that at least one tracking task sent by a network management system and received by the network element comprises the tracking task of the user, and then adds the tracking task into a tracking task set. Therefore, when the network element receives the call signaling of the user, the network element only needs to inquire the tracking task of the call signaling of the user from the tracking task set, and can send the call signaling to the network management system to complete the tracking task. The technical method not only prevents the network element from creating the tracking task of the user of which the call signaling does not pass through the network element, but also ensures that the network element can create the tracking task of the user of which the call signaling passes through the network element, and finally improves the resource utilization rate of the network element and the tracking efficiency of the call signaling of the user.
With reference to the first aspect or any one of the foregoing possible implementation manners, in a third possible implementation manner, the method further includes: the network element receives a logout request message carrying a second user identification number; the network element determines that the user identified by the second user identification number successfully logs in and logs out on the network element according to the logout request message; the network element determines that a tracking task comprising a second user identification number exists in at least one tracking task; the network element deletes the tracking task including the second subscriber identification number from the at least one tracking task.
When the user logs off from the network element, the tracking task of the user is deleted from the tracking task set in time, so that the tracking task set cannot comprise the tracking task which is not used for tracking the call signaling of the user temporarily, when the network element receives the call signaling, the number of the searched tracking tasks in the tracking task set is small, and the tracking efficiency of the network element is improved.
With reference to the first aspect or any one of the foregoing possible implementation manners, in a fourth possible implementation manner, the method further includes: the network element determines a second tracking task in the tracking task set; the network element determines that the user identified by the user identification number included in the second tracking task is not registered on the network element; the network element deletes the second tracking task from the set of tracking tasks.
The realization method can further delete the tracking task corresponding to the user which is not successfully registered on the network element from the tracking task set when the tracking task of the user cannot be deleted from the tracking task set in time due to some reasons after the user logs off from the network element, thereby further ensuring that the tracking task set does not comprise the tracking task which is not used for tracking the call signaling of the user temporarily, and leading the number of the searched tracking tasks in the tracking task set to be smaller when the network element receives the call signaling, thereby improving the tracking efficiency of the network element.
In a second aspect, there is provided a network element, comprising: the system comprises a receiving module, a processing module and a processing module, wherein the receiving module is used for receiving at least one tracking task sent by a network management system, and each tracking task comprises a user identification number of a user corresponding to the tracking task; the processing module is used for adding at least one tracking task comprising a user identification number of a user successfully registered on the network element to the tracking task set; the receiving module is also used for receiving a call signaling carrying the user identification number; a determining module, configured to determine that a tracking task including a user identification number carried by the call signaling exists in a tracking task set; and the sending module is used for sending the call signaling to the network management system.
The network element of the invention adds the tracking task to a tracking task set when determining that the tracking task comprising the user identification number of the user successfully registered on the network element exists in at least one tracking task received by the network management system. Therefore, when the network element receives the call signaling, the call signaling can be sent to the network management system to complete the tracking task only by inquiring the tracking task comprising the user identification number carried in the call signaling from the tracking task set. The technical method not only prevents the network element from creating the tracking task of the user of which the call signaling does not pass through the network element, but also ensures that the network element can create the tracking task of the user of which the call signaling passes through the network element, and finally improves the resource utilization rate of the network element and the tracking efficiency of the call signaling of the user.
With reference to the second aspect, in a first possible implementation manner, the processing module is specifically configured to: determining a first tracking task from at least one tracking task; determining that the user identified by the user identification number included in the first tracking task successfully registers on the network element; the first tracking task is added to the set of tracking tasks.

With reference to the second aspect or any one of the foregoing possible implementation manners, in a fourth possible implementation manner, the processing module is further configured to: determining a second tracking task in the tracking task set; determining that the user identified by the user identification number included in the second tracking task is not registered on the network element; the second tracking task is removed from the set of tracking tasks.
In a third aspect, a network element is provided, including: a processor, a memory, a bus system, a receiver, and a transmitter. Wherein the processor, the memory, the bus system, the receiver and the transmitter are connected by the bus system, the memory is used for storing instructions, the processor is used for executing the instructions stored by the memory, and the processor, the memory, the bus system, the receiver and the transmitter together execute the method for transmitting call signaling in the first aspect and various possible implementations thereof.
The network element of the invention determines the user equipment which is successfully registered and the tracking task which is sent by the network system, and when the network element determines that a certain user equipment in the user equipment which is successfully registered corresponds to a certain tracking task in the tracking task which is sent by the network system, the tracking task is added into a tracking task set. Therefore, when the UE initiates the call signaling, the call signaling of the UE can be sent to the network management system only by inquiring the tracking task of the call signaling of the UE from the tracking task set, and the tracking task is completed. The technical method not only prevents the network element from creating the tracking task of the UE of which the call signaling does not pass through the network element, but also ensures that the network element can create the tracking task of the UE of which the call signaling passes through the network element, and finally improves the resource utilization rate of the network element and the tracking efficiency of the call signaling of the UE.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For ease of understanding, an exemplary diagram of a network architecture in which the method of sending call signaling of embodiments of the present invention can be implemented is described generally. It should be understood that embodiments of the present invention are not limited to the network architecture shown in fig. 1.
The network architecture shown in fig. 1 includes a network management system 101, a network element 102, and a UE 103. In order to avoid repetition, only one network management system, one network element, and one UE are embodied in the network architecture shown in fig. 1, but the number of the network management system, the network element, and the UE in the network to which the method for sending the call signaling according to the embodiment of the present invention is applied is not limited. The network architecture shown in fig. 1 may be an IMS network.
In the Network architecture shown in fig. 1, the UE103 may communicate with one or more Core networks (Core networks) via a Radio Access Network (RAN). A UE may be referred to as an access terminal, terminal device, subscriber unit, subscriber station, mobile, remote station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or user equipment. The UE may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with Wireless communication capability, a computing device or other processing device connected to a Wireless modem, a vehicle mounted device, a wearable device, a terminal device in a future 5G network, and so on.
The UE103 may send various messages to the network element 102, such as a registration request message for requesting registration, a de-registration request message for requesting de-registration, or other call signaling.
In the embodiment of the invention, various communications between the user and the network element are realized by the UE used by the user.
In the network architecture shown in fig. 1, the network management system 101 may issue a tracking task of a user to the network element 102. The tracking task issued by the network management system 101 to the network element 102 needs to specify a user to be tracked, wherein the tracking task may be specified as a tracking task of a certain user by including a user identification number of the user in the tracking task. The Subscriber Identification Number may use a Mobile Subscriber integrated Service Digital Network Number (MSISDN) of the Subscriber, i.e., a Mobile phone Number, or an International Mobile Subscriber identity Number (IMSI), i.e., a unique identifier of a Mobile phone card. The network management system can also receive the call signaling of the UE reported by the network element and present the call signaling to a user of the network management system.
In the network architecture shown in fig. 1, the network element 102 may be a Proxy Call Session Control Function (P-CSCF), a Call Session Control Function (CSCF), a Home Subscriber Server (HSS), or the like. The network element 102 may receive the tracking task sent by the network management system 101 and keep the tracking task in the database; various messages sent by the user through the UE103 may also be received, such as call signaling sent by the user through the UE; call signaling sent by the user through the UE103 may also be sent to the network management system 101. It should be understood that the call signaling received by the network element 102 through the UE103 may be a call signaling sent by a user directly to the network element 102 through the UE103, or a call signaling sent by a user through the UE103 and reaching the network element 102 through one or more other network elements, but the call signaling includes a subscriber identification number of the user.
Fig. 2 is an exemplary flowchart of a method of transmitting call signaling according to an embodiment of the present invention. The method illustrated in fig. 2 may be performed by network element 102 in fig. 1.
S201, a network element receives at least one tracking task sent by a network management system, wherein each tracking task comprises a user identification number of a user corresponding to the tracking task.
After receiving at least one tracking task sent by the network management system, the network element may store the tracking tasks as a tracking task list. However, the network element does not use the tracking task list as a list for querying whether there is a tracking task of a user corresponding to the call signaling when the call signaling is received, that is, the tracking task in the tracking task list is in an inactive state, so for convenience of subsequent description, the at least one task received by the network element may be referred to as an inactive tracking task list.
S202, the network element adds at least one tracking task comprising the user identification number of the user successfully registered on the network element to a tracking task set.
After the network element obtains the tracking task from the network management system, the network element queries the tracking task including the user identification number of the user who has successfully registered on the network element from at least one tracking task (i.e. an inactive tracking task list), and then adds the tracking task to the tracking task set. The users identified by the user identification numbers included in the tracking tasks in the tracking task set are all users who have successfully registered on the network element, that is, the tracking tasks in the tracking task set are the tracking tasks of the users who have successfully registered on the network element. When the network element receives the call signaling, the tracking task set is used to query whether a tracking task of a user corresponding to the call signaling is included, that is, each tracking task in the tracking task set is in an active and available state, so for convenience of subsequent description, the tracking task set may be referred to as an activated tracking task list.
When a trace task in the inactive trace task list is added to the active trace task list, the trace task may be continuously retained in the inactive trace task list or deleted.
It should be noted that the user who has successfully registered with the network element in the embodiment of the present invention refers to a user who has successfully registered with the network element and has not logged off yet. A user that has been successfully registered but has been de-registered at the network element does not belong to a user who has successfully registered as described in the embodiments of the present invention.
S203, the network element receives a call signaling carrying the user identification number.
The call signaling received by the network element may be sent to the network element by the user directly through the UE, or may be sent to the network element by the user through one or more network elements after being sent by the user through the UE. The user identification number of the user is carried by the call signaling sent to the network element by the user directly through the UE or the call signaling sent to the network element by the user through one or more network elements after being sent by the user through the UE so as to identify the user to which the call signaling belongs.
S204, the network element determines that the tracking task including the user identification number carried by the call signaling exists in the tracking task set.
Because the call signaling received by the network element carries the user identification number of the user, and the tracking task also comprises the user identification number, the network element can inquire whether the tracking task comprising the user identification number carried in the call signaling exists from the activated tracking task list, and if the tracking task comprises the user identification number carried in the call signaling, the network element needs to track the call signaling carrying the user identification number.
S205, the network element sends the call signaling to the network management system.
The network element determines that the activated task list has a tracking task including the user identification number carried by the call signaling, so the network element sends the call signaling to the network management system to realize the tracking of the call signaling of the user identified by the user identification number carried by the call signaling.
In the method for sending the call signaling, when the network element determines that the tracking task comprising the user identification number of the user successfully registered on the network element exists in at least one tracking task received by the network management system, the tracking task is added into a tracking task set. Therefore, when the network element receives the call signaling, the call signaling can be sent to the network management system to complete the tracking task only by inquiring the tracking task comprising the user identification number carried in the call signaling from the tracking task set. The technical method not only prevents the network element from creating the tracking task of the user of which the call signaling does not pass through the network element, but also ensures that the network element can create the tracking task of the user of which the call signaling passes through the network element, and finally improves the resource utilization rate of the network element and the tracking efficiency of the call signaling of the user.
In this embodiment of the present invention, optionally, when the network element adds, to the tracking task set, a tracking task including a user identification number of a user successfully registered on the network element in at least one tracking task, a specific implementation manner may be: the network element determines a first tracking task from at least one tracking task sent by a network management system; and the network element determines that the first UE corresponding to the first tracking task is successfully registered on the network element. At this time, a schematic flowchart of a method of transmitting call signaling according to an embodiment of the present invention is shown in fig. 3.
The method described in fig. 3 may be performed by network element 102 in fig. 1. The same reference numerals as in fig. 2 are included in fig. 3 to indicate the same steps, and are not repeated here to avoid repetition. Only the steps contained in fig. 3 that differ from those in fig. 2 will be described below.
S302A, the network element determines a first tracking task from the at least one tracking task.
After receiving at least one tracking task (namely, an inactive tracking task list) sent by a network management system, a network element determines a certain tracking task from the inactive tracking task list, and for convenience of subsequent description, the tracking task is changed into a first tracking task.
S302B, the network element determines that the user identified by the user identification number included in the first tracking task is successfully registered with the network element.
After determining the first tracking task from the inactive tracking task list, the network element determines whether the user identified by the user identification number included in the first tracking task is successfully registered in the network element.
S302C, the network element adds the first tracking task to the set of tracking tasks.
When the network element determines that the user identified by the user identification number included in the first tracking task has successfully registered on the network element, the network element adds the first tracking task to the tracking task set (i.e., the activated tracking task list). Thus, when receiving the call signaling, the network element may query whether there is a tracking task including the user identification number carried by the call signaling in the activated tracking task column, to determine whether the call signaling needs to be sent to the network management system, thereby implementing the tracking of the call signaling.
The above three steps may be repeated until all tracking tasks identified by all the user identification numbers included in the inactive tracking task list, which are successfully registered by the user on the network element, are added to the inactive tracking task list.
Because the tracking tasks included in the activated tracking task list are mixed with the tracking tasks of the users who are registered successfully on the network element, the inquiry is carried out in the activated tracking task list instead of the inactivated tracking task list, so that the inquiry efficiency can be improved, and the resource utilization rate of the network element is further improved.
In this embodiment of the present invention, optionally, when the network element adds, to the tracking task set, a tracking task including a user identification number of a user successfully registered on the network element in at least one tracking task, a specific implementation manner may be: a network element receives a registration request message carrying a first user identification number; the network element determines that the user identified by the first user identification number is successfully registered on the network element according to the registration request message; the network element determines that a tracking task comprising a first user identification number exists in at least one tracking task; the network element adds the tracking task of which at least one tracking task comprises the first user identification number to the tracking task set. At this time, a schematic flowchart of a method of transmitting call signaling according to an embodiment of the present invention is shown in fig. 4.
The method described in fig. 4 may be performed by network element 102 in fig. 1. The same reference numerals in fig. 4 and fig. 2 denote the same steps, and are not repeated here to avoid repetition. Only the steps contained in fig. 4 that differ from those in fig. 2 will be described below.
S402A, the network element receives a registration request message carrying the first subscriber identity number.
In the network, the UE used by the user initiates a registration process to the network element when the UE is powered on, and continues to initiate services such as a call to the network element after the registration is successful. Therefore, the user sends a registration request message to the network element through the UE, and accordingly, the network element receives the registration request message sent by the user through the UE. The registration request message carries the subscriber identity number of the subscriber, which is referred to as the first subscriber identity number for the purpose of the following description.
S402B, the network element determines, according to the registration request message, that the user identified by the first user identification number successfully registers on the network element.
After receiving a registration request message sent by a user through UE, the network element processes the registration request of the user according to the registration request message, and then determines whether the user identified by the first user identification number is registered successfully on the network element.
S402C, the network element determines that a tracking task including the first subscriber identification number exists in the at least one tracking task.
And after the network element determines that the user identified by the first user identification number successfully registers on the network element, judging whether the tracking task comprising the first user identification number exists in the inactive tracking task list or not.
S402D, the network element adds a tracking task including the first subscriber identity number to the set of tracking tasks.
When the network element determines that the user identified by the first user identification number is successfully registered on the network element and determines that the tracking task including the first user identification number exists in the inactive tracking task list, it indicates that the call signaling of the user identified by the first user identification number needs to be tracked. The tracking task including the first user identification number in the at least one tracking task is thus added to the set of tracking tasks, i.e. to the list of activated tracking tasks.
When the network element adds a tracking task including a first user identification number in at least one tracking task to the activated tracking task list, the network element may query whether there is a tracking task including a user identification number carried by a call signaling in the activated tracking task list when receiving the call signaling. If the activated tracking task list inquires a tracking task comprising a user identification number carried by the call signaling, the call signaling is sent to a network management system to realize the tracking of the call signaling.
Because the inquiry is carried out in the activated tracking task list, but not in the inactivated tracking task list, the inquiry information can be improved, namely, the tracking efficiency and the resource utilization rate of the network element are improved.
The methods for sending call signaling shown in fig. 3 and fig. 4 may be combined for use, that is, when a network element receives a tracking task sent by a network management system, it is determined whether a user identified by a user identification number included in the tracking task has successfully registered with the network element, and if the registration is successful, the tracking task is added to an activated tracking task list. When the network element receives the registration request message of the user and determines that the user is successfully registered on the network element, whether the tracking task of the user exists in the inactive tracking task list or not is judged, and if so, the tracking task is added to the active tracking task list. Therefore, the tracking tasks of the users successfully registered on the network element can be ensured to be activated, the users corresponding to the activated tracking tasks can be ensured to be the users successfully registered on the network element, and finally, the query efficiency and the resource utilization rate are improved.
FIG. 5 is a schematic flow chart diagram of a method of updating an activated tracking task list in accordance with another embodiment of the present invention. The method illustrated in fig. 5 may be performed by network element 102 in fig. 1.
S501, the network element receives a logout request message carrying a second user identification number.
When the UE used by the user is powered off or under some other conditions, the UE sends a logout request message to the network element to initiate a logout procedure to request logout from the network. The logout request message carries a user identification number of the user, and for convenience of subsequent description, the user identification number may be referred to as a second user identification number.
S502, the network element determines that the user identified by the second user identification number successfully logs in and logs off the network element according to the logout request message.
The network element determines that the user identified by the second user identification number successfully logs in and off the network element according to the logout request message, and at this time, the registration state of the user identified by the first user identification number can be stored as unregistered.
S503, the network element determines that a tracking task including the second subscriber identity number exists in the at least one tracking task.
And after the network element determines that the user identified by the second user identification number successfully logs out on the network element, judging whether the tracking task comprising the second user identification number exists in the activated tracking task list or not.
S504, the network element deletes the tracking task including the second subscriber identity number from the at least one tracking task.
And when the network element determines that the tracking task comprising the second user identification number exists in the activated tracking task list, deleting the tracking task from the activated task list.
In the embodiment of the invention, when the user successfully logs in and off the network element, if the activated tracking task list comprises the tracking task corresponding to the user, the tracking task corresponding to the user in the activated tracking task list is deleted, so that the tracking tasks in the activated tracking task list are all the tracking tasks corresponding to the users who successfully log in and off the network element, thereby ensuring that the tracking tasks used for querying are prevented from comprising a large number of tracking tasks corresponding to unregistered users when querying the tracking tasks of no users, and finally improving the querying efficiency and the resource utilization rate.
It should be noted that the network element only deletes the tracking task corresponding to the user in the activated tracking task list, and does not delete the tracking task corresponding to the user in the inactivated tracking task list. In this way, when the user successfully registers on the network element again, the tracking task corresponding to the user can be added to the activated tracking task list from the inactive tracking task list.
In some abnormal scenarios, such as UE registration or de-registration, the tracking task set may not be refreshed correctly according to the state of the UE. If the UE logs off, the tracking task corresponding to the UE in the tracking task set cannot be successfully deleted. At this time, in order to ensure that the tracking tasks in the tracking task set (i.e., the activated tracking task list) are all the tracking tasks corresponding to the users who have successfully registered, thereby ensuring the tracking efficiency and the resource utilization rate, the network element needs to periodically check whether the users corresponding to the tracking tasks in the tracking task set are the users who have successfully registered. And if the user corresponding to the tracking task is not registered successfully, deleting the tracking task from the tracking task set.
FIG. 6 is a schematic flow chart diagram of a method of updating an activated tracking task list in accordance with another embodiment of the present invention. The method illustrated in fig. 6 may be performed by network element 102 in fig. 1.
S601, the network element determines a second tracking task in the tracking task set.
The network element determines one or more tracking tasks from the list of activated tracking tasks, which for the purposes of the following description will be referred to as second tracking tasks.
S602, the network element determines that the user identified by the user identification number included in the second tracking task is not registered on the network element.
And after determining that the second tracking task is determined from the activated tracking tasks, the network element judges whether the user identified by the user identification number included in the second tracking task is not registered on the network element. The term subscriber not registered with the network element as used herein includes subscribers who never successfully register with the network element, and subscribers who successfully register with the network element but who successfully deregister.
S603, the network element deletes the second tracking task from the tracking task set.
And when the network element determines that the user identified by the user identification number included by the second tracking task in the activated tracking task list is not registered on the network element, deleting the second tracking task from the activated tracking task list.
However, it should be noted that if the trace task in the inactive trace task list is not deleted when the trace task in the inactive trace task list is added to the active trace task list, the trace task in the active trace task list may be directly deleted here. If the trace task in the inactive trace task list is deleted while the trace task in the inactive trace task list is added to the active trace task list, the trace task deleted in the active trace task list should be added to the inactive trace task list at this time. The purpose of this is to keep a record of all tracking tasks on the network element, so that when a user who is not registered on the network element successfully registers with the network element, the tracking task of the user can be queried from the inactive tracking task list, and thus the tracking task is added to the active tracking task list, so as to realize the tracking of the call signaling of the user.
When the network element executes the method, it may specifically be that the tracking task set is checked at regular time (e.g. every half hour or hour).
The method for sending call signaling and the method for updating the activated tracking task list according to the embodiment of the present invention are described in detail above with reference to fig. 2 to 6, and the network element according to the embodiment of the present invention is described below with reference to fig. 7 and 8.
