Description

IMS request message sending method and device

Technical Field

The application belongs to the technical field of communication, and particularly relates to a method and a device for sending an IMS request message.

Background

Most operators worldwide have now supported internet multimedia subsystem (IP Multimedia Subsystem, IMS) services, such as Voice over Long-Term Evolution (VoLTE), high definition Video telephony (Video over LTE, LTE), wi-Fi telephony (WFC), etc.

Among other things, IMS employs session initiation protocol (Session Initiation Protocol, SIP) to enable communication. SIP employs a request/response mechanism, i.e., a request message, corresponding to a terminating response message. Whether the request was successful or not is known from the response message.

In addition, at present, each sub-service support of the IMS network of each operator is different, and the electronic device (for example, the terminal) will be preconfigured according to the default value according to the support condition of each sub-service of the network of the corresponding operator. However, when a certain sub-service of the operator is changed, the terminal fails to receive the change notification, and the request of the sub-service will fail.

However, the failure reasons included in the response message for some IMS request failures are often not clear enough at present, and only one general reason suggests that the terminal cannot make accurate request changes and resend the IMS request message, thereby affecting normal use of the user.

As can be seen from this, in the prior art, after the electronic device receives some types of failure response messages for the IMS request message, the success rate of retransmitting the IMS request message is low.

All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The following describes in detail, with reference to the attached drawings, a specific embodiment and an application scenario thereof, a method for sending an IMS request message provided in the embodiment of the present application.

Fig. 1 is a flowchart of a method for sending an IMS request message according to an embodiment of the present application, where the method may include the following steps:

step 101: after receiving the target failure response message, the electronic equipment determines whether the target failure response message belongs to a message of a first preset type.

Wherein IMS represents the internet multimedia subsystem. The target failure response message is a failure response message of the first IMS request message. After the electronic device sends the first IMS request message to the sixth target network element, if the sixth target network element does not support the first IMS request message, the electronic device receives the target failure response message. The sixth target network element is a proxy call session control function (Proxy Call Session Control Function, PCSCF) network element.

The SIP capability included in an IMS request message belongs to the SIP capability supported by a PCSCF network element, and the PCSCF network element supports the IMS request message; SIP capabilities not supported by the PCSCF network element exist in SIP capabilities included in an IMS request message, and the PCSCF network element does not support the IMS request message.

In addition, when the target failure response message is a message of a first preset type, the electronic device cannot modify the first IMS request message according to the target failure response message, so that the sixth target network element can successfully receive the first IMS request message.

Step 102: and under the condition that the target failure response message belongs to the first preset type of message, the electronic equipment searches a first target network element in a target set.

After the electronic device registers the IMS, the network side configures a network element other than the network element sending the target failure response message in the network elements represented by the PCSCF address configured for the electronic device, where the first target network element is a network element supporting the first IMS request message. Thus, the SIP capability included in the first IMS request message belongs to the SIP capability supported by the first target network element, and after the electronic device sends the first SIM request message to the first target network element, the first target network element may successfully receive the first SIM request message.

For example, after the electronic device IMS registers, the network side configures 3 PCSCF addresses for the network side, if the electronic device receives a failure response message sent by the network element indicated by the first PCSCF address after sending the first SIM request message to the network element indicated by the first PCSCF address, the electronic device determines whether the failure response message belongs to a first preset type of message, if yes, the electronic device may search for a network element supporting the first SIM request message from other network elements except for the network element indicated by the first PCSCF address in the network elements indicated by the 3 PCSCF addresses.

Step 103: and under the condition that the first target network element is found in the target set, the electronic equipment sends the first IMS request message to the first target network element.

As can be seen from the above, in the embodiment of the present application, after receiving the target failure response message of the first IMS request message, the electronic device may determine whether the target failure response message belongs to a first preset type of message, and if so, search a first target network element supporting the first IMS request message in the target set, so as to send the first IMS request message to the first target network element when the first target network element is searched. Wherein the PCSCF supporting the first IMS request message may successfully receive the first IMS request message. Therefore, in the embodiment of the application, the electronic device sends the first IMS request message to the first target network element, and the first target network element can successfully receive the first SIM request message, so that the success rate of resending the IMS request message after the electronic device receives some types of failure response messages for the IMS request message can be improved to a certain extent.

Optionally, determining, in step 101, whether the target failure response message belongs to a first preset type of message may include:

Determining whether a first state code belongs to a state code of a second preset type and whether first prompt information belongs to prompt information of a third preset type, wherein the first state code is the state code included in the target failure response message, and the first prompt information is the prompt information included in the target failure response message;

determining that the target failure response message belongs to the first preset type message under the condition that the first state code belongs to the second preset type state code and the first prompt message belongs to the third preset type prompt message;

and determining that the target failure response message does not belong to the first preset type message under the condition that the first state code does not belong to the second preset type state code or the first prompt message does not belong to the third preset type prompt message.

The second preset type of status code is a pre-recorded status code, and the third preset type of prompt information is a pre-recorded prompt information.

The failure response message of the SIM request message includes a status code and prompt information, where the status code is used to indicate a reason that the SIM request message is not successfully received, and the prompt information is a prompt information for the reason that the SIM request message indicated by the status code is not successfully received. According to certain types of status codes and prompt messages, the electronic device cannot modify the first SIM request message so that the first SIM request message is successfully received, the status codes and the prompt messages can be recorded, so that after the electronic device receives a failure response message of one SIM request message, the electronic device can respectively determine whether the status codes included in the failure response message belong to the pre-recorded status codes and whether the prompt messages included in the failure response message belong to the pre-recorded prompt messages, and can determine whether the failure response message belongs to the first preset type message, namely, the status codes and the prompt messages in the failure response message are not clear enough, so that the electronic device cannot modify the first IMS request message so that the first IMS request message is successfully received.

Optionally, step 102: the electronic device searching for the first target network element in the target set may include:

step H1: traversing network elements in the target set, when encountering an ith network element, sending a SIP selection message (namely a SIP option message) to the ith network element, and receiving the ith capability information returned by the ith network element, wherein the ith capability information comprises SIP capability supported by the ith network element, i is an integer from 1 to N, N is the number of the network elements in the target set, and SIP represents a session initiation protocol;

step H2: under the condition that the SIP capability carried in the first IMS request message belongs to the SIP capability included in the ith capability information, determining that the first IMS request message is supported by the ith network element, and determining the ith network element as the first target network element;

step H3: and in the SIP capability carried in the first IMS request message, determining that the first IMS request message is not supported by the ith network element when the SIP capability not included in the ith capability information exists.

For example, after the electronic device performs IMS registration, the network side configures 3 PCSCF addresses for the electronic device, if the electronic device receives a failure response message sent by the network element indicated by the first PCSCF address after sending the first SIM request message to the network element indicated by the first PCSCF address, and the failure response message belongs to a first preset type of message, the electronic device first sends an SIP option message to the network element indicated by the second PCSCF address, so as to receive SIP capability supported by the network element indicated by the second PCSCF address returned by the network element indicated by the second PCSCF address.

If the SIP capability included in the first SIM request message belongs to the SIP capability supported by the network element indicated by the second PCSCF address (i.e., the set of SIP capabilities included in the first SIM request belongs to a subset of the set of SIP capabilities supported by the network element indicated by the second PCSCF address), the network element indicated by the second PCSCF address is the network element supporting the first SIM request message.

If the SIP capability not belonging to address support indicated by the second PCSCF address exists in the SIP capability included in the first SIM request message, the network element indicated by the second PCSCF address does not support the first SIM request message. At this time, the electronic device is required to send the SIP option message to the network element indicated by the third PCSCF address, so as to continue to search for the network element supporting the first SIM request message.

Optionally, step 103: in the case that the first target network element is found in the target set, after the electronic device sends the first IMS request message to the first target network element, the method may further include: and modifying the SIP capability supported by the first target network element recorded in the electronic equipment according to the SIP capability supported by the first target network element.

In the embodiment of the present application, after the first IMS request message is sent to the first target network element, the SIP capability supported by the first target network element at this time may be used as the latest SIP capability supported by the first target network element, so that the SIP capability supported by the first target network element that is already recorded in the electronic device is modified to be the latest SIP capability, thereby reducing to a certain extent the probability that the first target network element cannot successfully receive when the subsequent electronic device sends the SIM request message to the first target network element again.

When the steps H1 to H3 are adopted to search the first target network element in the target set, the SIP capability supported by the first target network element is obtained in the process of searching the first target network element in the target set, and the SIP capability supported by the first target network element obtained in the process of searching the first target network element in the target set can be used as the latest SIP capability supported by the first target network element.

Optionally, after the electronic device determines in step 101 whether the target failure response message belongs to a message of a first preset type, the sending method of the IMS request message further includes:

under the condition that the first target network element is not found in the target set, selecting one network element from the target set to serve as a second target network element;

and sending a second IMS request message to the second target network element according to the SIP capability supported by the second target network element.

It can be known that, in the embodiment of the present application, when the first target network element is not found in the target set, one network element may be selected from the target set, and the IMS request message is resent according to the SIP capability supported by the network element, so as to further improve the success rate of the SIM request.

Optionally, the SIP capability includes: SIP method, extension type and content type; the selecting one network element from the target set as the second target network element may include:

step K1: acquiring a third target network element with the largest number of supported SIP methods in the target set;

step K2: in the presence of one of the third target network elements, determining the third target network element as the second target network element with the highest SIP capability;

step K3: acquiring a fourth target network element with the largest support expansion type in at least two third target network elements under the condition that the at least two third target network elements exist;

step K4: in the presence of one of the fourth target network elements, determining the fourth target network element as a second target network element with the highest SIP capability;

step K5: acquiring a fifth target network element with the highest supported content type in at least two fourth target network elements under the condition that the at least two fourth target network elements exist;

step K6: in the presence of one of the fifth target network elements, determining the fifth target network element as a second target network element with the highest SIP capability;

Step K7: and selecting one network element from at least two fifth target network elements to be used as a second target network element with the highest SIP (session initiation protocol) supporting capability when the at least two fifth target network elements exist.

As can be seen from the foregoing, the SIP capability supported by one PCSCF network element includes three contents of a SIP method, an extension type, and a content type, so in the embodiment of the present application, one network element may be selected from the target set according to the priority order of the three contents, so as to be used as the second target network element.

For example, the priority of the SIP method is higher than the priority of the extension type, and the priority of the extension type is higher than the priority of the content type, then the PCSCF supporting the most SIP method types in the target set is searched out first; if a plurality of PCSCFs with the largest variety of the SIP method exist, searching the PCSCFs with the largest variety of the SIP method from the plurality of PCSCFs with the largest variety of the SIP method; if a plurality of PCSCFs with the most supported extension types still exist, continuing to search the PCSCFs with the most supported content types in the plurality of PCSCFs with the most supported extension types; if there are still a plurality of PCSCFs with the most supported content types, selecting one of the PCSCFs with the most supported content types as a second target network element.

The second target network element selected from the target set through the steps K1 to K7 may be referred to as the most capable network element in the target set.

It should be noted that, the method for selecting the second target network element from the target set is not limited to this, and for example, the sum of the number of SIP methods, the number of extension types, and the number of content types supported by each PCSCF in the target set may be compared to obtain the target parameter corresponding to each PCSCF, so as to find the PCSCF with the maximum target parameter as the second target network element.

Optionally, the sending, according to the SIP capability supported by the second target network element, a second IMS request message to the second target network element may include:

modifying the first IMS request message according to the SIP capability supported by the second target network element to obtain a second IMS request message;

and sending the second IMS request message to the second target network element.

As can be seen from the foregoing, in the embodiments of the present application, the first SIM request message may be modified according to SIP capabilities supported by the second target network element, so that the second SIM request message obtained after modification is sent to the second target network element, thereby avoiding regeneration of the second SIM request message, and further shortening the sending time of the SIM request message to a certain extent.

Optionally, the modifying the first IMS request message according to the SIP capability supported by the second target network element includes:

and deleting the SIP capability which is not supported by the second target network element in the SIP capability carried in the first IMS request message.

The second target network element is a PCSCF network element that does not support the first IMS request message, and SIP capabilities that do not belong to the second target network element support exist in SIP capabilities carried in the first IMS request message, so that SIP capabilities that do not belong to the second target network element support in the first IMS request message can be deleted to obtain a second IMS request message, so that the second target network element supports the second IMS request message.

In addition, if the SIP capability includes a SIP method, an extension type, and a content type, the process of deleting the SIP capability that is not supported by the second target network element in the SIP capability carried in the first IMS request message specifically includes:

deleting the SIP methods which are not supported by the second target network element in the SIP methods carried in the first IMS request message;

deleting the extension types which are not supported by the second target network element in the extension types carried in the first IMS request message;

And deleting the content types which are not supported by the second target network element in the content types carried in the first IMS request message.

Optionally, after the sending the second IMS request message to the second target network element, the method further includes:

and modifying the SIP capability supported by the second target network element recorded in the electronic equipment according to the SIP capability supported by the second target network element.

In the embodiment of the present application, after the second IMS request message is sent to the second target network element, the SIP capability supported by the second target network element at this time may be used as the latest SIP capability supported by the second target network element, so that the SIP capability supported by the second target network element that is already recorded in the electronic device is modified to be the latest SIP capability, thereby reducing to a certain extent the probability that the second target network element cannot successfully receive the SIM request message when the subsequent electronic device re-sends the SIM request message to the second target network element.

When the steps H1 to H3 are adopted to search the first target network element in the target set, the SIP capability supported by the second target network element is obtained in the process of searching the first target network element in the target set, and the SIP capability supported by the second target network element obtained in the process of searching the first target network element in the target set can be used as the latest SIP capability supported by the second target network element.

As can be seen from the foregoing, in the embodiments of the present application, after the electronic device registers the IMS, the network side allocates a plurality of PCSCF addresses to the electronic device, so the electronic device records the plurality of PCSCF addresses after registering the IMS. After sending a first IMS request message to a network element represented by one PCSCF address, if a failed response message is received, and the status code and content prompt of the response message are not clear enough, so that the electronic device cannot make accurate request message change, the electronic device firstly performs capability query on other PCSCF network elements through an option method of SIP, thereby obtaining the information of SIP method, extension type, content type and the like supported by the network element represented by the recorded PCSCF address in the electronic device.

If it is queried that there is a SIP method, an extension, a content type, etc. supported by a network element represented by a PCSCF address that can support the first IMS request message, the electronic device attempts to resend the first IMS request message to the network element represented by the PCSCF address, and the electronic device may modify the SIP method, the extension type, and the content type supported by the network element represented by the PCSCF address, which are already stored in the electronic device, according to the SIP method, the extension type, and the content type supported by the PCSCF address, so that the subsequent IMS request messages are all sent to the PCSCF network element.

If the PCSCF network element capable of supporting the first IMS request message is not queried, firstly, the most-capable network element (namely, the network element selected through the process described in the steps K1-K7) in the network element represented by the recorded PCSCF address in the electronic equipment is found, then the content of the first IMS request message is regulated according to the supporting condition of the PCSCF to obtain a second IMS request message, so that the second IMS request message is sent to the PCSCF, and the electronic equipment can also modify the SIP method, the extension type and the content type supported by the network element represented by the PCSCF address which are stored in the electronic equipment according to the SIP method, the extension type and the content type condition supported by the PCSCF, so that the subsequent IMS request message is sent to the PCSCF, and the continuous failure of the subsequent request is avoided, and the use of a user is influenced.

In summary, as shown in fig. 2, a specific implementation manner of the method for sending an IMS request message in the embodiment of the present application may specifically include the following steps:

step 201: after the electronic equipment is registered in the IMS, the network side configures a plurality of PCSCF addresses for the electronic equipment;

step 202: the electronic device records these PCSCF addresses locally, e.g., PCSCF1 … PCSCFn;

Step 203: after the electronic equipment sends a first IMS request message to a network element represented by a PCSCF1 address, receiving a response message of the first IMS request message;

step 204: the electronic equipment analyzes the response message of the received first IMS request message;

step 205: determining whether the response message is a failed response message, if not, ending, if so, executing step 206;

step 206: determining whether the status code included in the response message and the failure cause indicated by the prompt message are clear (i.e. determining whether the status code included in the failure response message is a status code of a second preset type and whether the prompt message included in the failure response message is a prompt message of a third preset type), if yes, executing step 207, if no, executing step 208;

step 207: modifying the first IMS request message according to the prompt information included in the response message, and retransmitting;

step 208: the electronic equipment sends an SIP option message to a network element represented by the next PCSCF address, and inquires out an SIP method, an expansion type and a content type supported by the network element;

step 209: determining whether the network element supports the first IMS request message, if so, executing step 210, and if not, executing step 212;

Step 210: the electronic equipment sends a first IMS request message to the network element;

step 211: the electronic equipment modifies the method, the extension type and the content type supported by the network element which are stored before the local according to the SIP method, the extension type and the content type supported by the network element, so that the subsequent IMS request is sent to the network element indicated by the PCSCF address;

step 212: determining whether the PCSCF address is the last one of the stored PCSCF addresses in the electronic device, if not, executing step 208, if so, executing step 213;

step 213: the electronic equipment finds out the most-capable network element (namely, the network element selected through the process described in the steps K1-K7) from the locally stored PCSCF address representation network elements;

step 214: according to the method, extension type and content type of SIP supported by the network element, the content of the first IMS request message is changed, and the changed IMS request message is continuously sent to the PCSCF, so that step 211 is performed after the changed IMS request message is sent to the PCSCF.

Therefore, in the embodiment of the present application, after the electronic device performs IMS registration, when a call needs to be performed or an instant communication message needs to be sent, a first IMS request message is sent to a PCSCF network element, but a failure response message is received, and a status code and a failure cause of a prompt message included in the response message are not clear enough, so that when the electronic device cannot accurately change the request message and resend the request message, the electronic device may attempt to find the PCSCF network element supporting the first IMS message by traversing the PCSCF address manner acquired after IMS registration, and if the address is not found, resend the IMS request message from the PCSCF network element with the highest capability (i.e., the network element selected through the process described in steps K1 to K7) so as to improve the successful receiving rate of the IMS request message.

It should be noted that, in the method for sending an IMS request message provided in the embodiment of the present application, the execution body may be a sending device of the IMS request message, or a control module in the sending device of the IMS request message, which is configured to execute the method for sending the IMS request message.
