For terminals supporting IMS services, it is necessary to adapt IMS signaling parameters to different operator networks. In IMS services, IMS signaling anomalies often occur due to missing IMS signaling parameters or modified network parameters, resulting in abnormal IMS services. For example, a voice call anomaly caused by the lack of configuration parameters. Summary of the Invention

[0024] Next, the embodiments in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application fall within the scope of protection of the present application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0026] The abnormal network service recovery method, device, electronic device and server provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0027] like Figure 1 As shown, the embodiment of the present application provides a method for recovering abnormal network services, including:

[0028] Step 102: The user terminal sends a first request message to the electronic device, where the first request message includes configuration parameters to be calibrated.

[0029] In some embodiments of the present application, a user terminal sends a service request to a network service subject, and when the network service subject responds successfully, the network service subject will send data to the user terminal to provide network services. If there is missing information or invalid information in the service request sent by the user terminal to the network service subject, at this time, the network service subject will not successfully respond to the service request, such as not feeding back information to the user terminal, or feeding back information such as abnormal service request to the user terminal. At this time, the user terminal sends a first service request to the electronic device so as to use the electronic device to assist the user terminal in updating the service request, and then initiate the network service according to the updated service request. Among them, the user terminal sends a service request to the network service subject, and the network service subject provides services to the user terminal after receiving the service request. Based on this, the configuration parameters are the parameters that the network service subject needs to use when providing service requests to user terminals.

[0030] For example, in the case where the network service is an IMS service, the configuration parameter may be one or more of IMS registration related signaling, telephone negotiation signaling, and supplementary service signaling.

[0031] For example, the configuration parameters are media negotiation parameters in an INVITE message for establishing a normal call.

[0032] Specifically, the configuration parameters are audio media parameters, such as: m = audio 42046 RTP / AVP 98 96 105 100 - indicating media type (audio / video), local port number (audio port number 42046), transport protocol (RTP / AVP), and media formats (four types: 98, 96, 105, 100);

[0033] b = AS:49 - The maximum application - related bandwidth is 49 Kbps;

[0034] b = RS:612 - The maximum data - sending bandwidth is 612 Kbps;

[0035] b = RR:1837 - The maximum data - receiving bandwidth is 1837 Kbps;

[0036] a = rtpmap:98 AMR - WB / 16000 / 1 - rtpmap: media format codec type / sampling rate / number of channels;

[0037] a = ptime:20 - The number of media packets encapsulated is 20 ms;

[0038] a = maxptime:240 - The maximum number of media packets encapsulated is 240 ms;

[0039] a = rtpmap:96 AMR / 8000 / 1 - rtpmap: media format codec type / sampling rate / number of channels;

[0040] a = rtpmap:105 telephone - event / 16000 - rtpmap: media format media type / sampling rate;

[0041] a = rtpmap:100 telephone - event / 8000;

[0042] a = fmtp:98 mode - change - capability = 2; max - red = 0 - fmtp: media format media parameters (2 indicates that the client can transmit with a limited mode - change period), media parameter (indicating the maximum number of redundant transmission frames in ms);

[0043] a = fmtp:96 mode - change - capability = 2; max - red = 0;

[0044] a = fmtp:105 0 - 15 - fmtp: media format can handle DTMF tones (0 - 15);

[0045] a = fmtp:100 0 - 15.

[0046] Specifically, the configuration parameters are video media parameters. For example: m = video 65396 RTP / AVP 114 115 -- indicating media type (audio / video), local port number (video port number 65396), transport protocol (RTP / AVP), and media format (two types 114 115);

[0047] b = AS:2162 -- the maximum application-related bandwidth is 2162 Kbps;

[0048] b = RS:8000 -- the maximum data sending bandwidth is 8000 Kbps;

[0049] b = RR:6000 -- the maximum data receiving bandwidth is 6000 Kbps;

[0050] a = tcap:1 RTP / AVPF -- transmission capacity attribute;

[0051] a = pcfg:1 t = 1 -- based on the capacity attribute, possible configuration parameters;

[0052] a = rtpmap:114 H264 / 90000 -- rtpmap: media format / media type / sampling rate;

[0053] a = rtpmap:115 H264 / 90000;

[0054] a = fmtp:114 profile-level-id = 42C01F; packetization-mode = 1; sprop-parameter-sets = Z0LAH42NQFoFDTUFAgIHhEIpwA==,aMpDyA== -- fmtp: media type media profile level RTP payload type attribute or capabilities supported by the receiver, initial NAL unit header parameters;

[0055] a = fmtp:115 profile-level-id = 42C01F; packetization-mode = 0; sprop-parameter-sets = Z0LAH42NQFoFDTUFAgIHhEIpwA==,aMpDyA== a = rtcp-fb:* nack -- the a = rtcp-fb attribute is a declarative media-level attribute used to indicate which RTCP-based feedback messages can be sent and received for the relevant media stream, feedback type (nack);

[0056] a = rtcp-fb:*nack pli —— a = rtcp-fb: Support for negative acknowledgement (nack) picture loss indication feedback (pli) for feedback;

[0057] a = rtcp-fb:*ccm fir —— a = rtcp-fb: Support for codec control (ccm codec control using RTCP feedback message) to support full intra request;

[0058] a = rtcp-fb:*trr-int 1000 —— RTCP packet minimum interval 1000 ms;

[0059] a = rtcp-fb:*ccm tmmbr —— a = rtcp-fb: Support for codec control (ccm codec control using RTCP feedback message) to support temporary maximum media bitrate request (tmmbr the receiver is currently bandwidth limited and tells the sender to control the bitrate);

[0060] a = extmap:7urn:3gpp:video-orientation —— Uniform Resource Name for video stream with orientation coordination (local identifier is 7).

[0061] Specifically, the configuration parameters are in the Register request message: the information contained in the Contact header field and the information contained in the Authorization header field;

[0062] Contact:<sip:[2409:811e:9862:3b69:1:0:b52d:991a]:5060>;+sip.instance=" <urn:gsma:imei:86439906-457047-0>"; +g.3gpp.icsi-ref = "urn%3Aurn-7%3A3gpp-service.ims.icsi.mmtel"; +g.3gpp.smsip; +g.3gpp.accesstype = "cellular2"; audio; video, that is, Contact header field information;

[0063] Authorization: Digest username = "460079900340700@ims.mnc007.mcc460.3gppnetwork.org", realm = "ims.mnc007.mcc460.3gppnetwork.org", nonce = "", uri = "sip:ims.mnc007.mcc460.3gppnetwork.org", response = "", that is, Authorization header field information;

[0064] Specifically, the configuration parameter can be a supplementary service, such as X-3GPP-Intended-Identity: sip:+xxxxxx@ims.mnc872.mcc405.3gppnetwork.org.

[0065] Specifically, that is, X-3GPP-Intended-Identity header field information.

[0066] Specifically, the configuration parameter can be an emergency call, such as:

[0067] INVITE urn:service:sos.fire SIP / 2.0, that is, INVITE request line.

[0068] From: <sip:+xxxx@sn.ims.mnc011.mcc460.3gppnetwork.org>; tag = vJxzReK7nL1siA, that is, From header field information.

[0069] Recv-Info: g.3gpp.current-location-discovery, that is, Recv-Info header field information.

[0070] To: <urn:service:sos.fire>, that is, To header field information.

[0071] In some embodiments of the present application, a network service can be understood as a service-oriented software module based on a distributed program running on a network, such as a network resident service, an Internet access service, etc.

[0072] In some embodiments of the present application, when the user terminal needs a network service, a first request message is sent to the electronic device.

[0073] In this embodiment, it can be understood that every time the user terminal needs a network service, a first request message will be sent to the electronic device to update the service request.

[0074] In some embodiments of the present application, when the user terminal sends a network request to the network service provider and does not receive a successful response from the network service provider, a first request message is sent to the electronic device.

[0075] In this embodiment, when the user terminal sends a network request to the network service provider and does not receive a successful response from the network service provider, it is considered that the service request used by the user terminal when initiating the network service is abnormal. At this time, a first request message is sent to the electronic device to update the service request. In some embodiments of the present application, the user terminal sends a first request message to the electronic device every first time period.

[0076] In this embodiment, it can be understood that the user terminal updates the service request every first time period.

[0077] In this embodiment, the first time period can be set according to actual usage needs, such as one day, one week, one month, etc. The specific value is not elaborated here.

[0078] In some embodiments of the present application, the electronic device and the user terminal are in the same local area network so that the user terminal and the electronic device can communicate with each other.

[0079] Specifically, for example, the user terminal and the electronic device are connected to the same router, such as connected to the same network hotspot, or can also be under the same server.

[0080] In some embodiments of the present application, the electronic device and the user terminal are respectively within each other's communication range, where the communication range can be the Bluetooth communication distance between the user terminal and the electronic device.

[0081] In some embodiments of the present application, the electronic device can be a terminal of the same type as the user terminal or a server.

[0082] Specifically, for example, if the Bluetooth communication range of the user terminal is 3 meters and the Bluetooth communication range of the electronic device is 2 meters, and the distance between the user terminal and the electronic device is less than 2 meters, then the electronic device and the user terminal are each within the communication range of the other.

[0083] Step 104, the electronic device receives a first request message sent by the user terminal.

[0084] Step 106, the electronic device sends a first response message to the user terminal.

[0085] Step 108, the user terminal receives the first response message sent by the electronic device, and the first response message includes calibrated configuration parameters.

[0086] Step 110, the user terminal updates the service request according to the calibrated configuration parameters.

[0087] In this embodiment, updating the service request means modifying the original service request to obtain a modified service request.

[0088] Specifically, for example, the value of a certain specific configuration parameter in the original service request is 1, and the value of this specific configuration parameter is modified from 1 to 2. At this time, the specific configuration parameter in the service request has changed, so the changed service request is updated compared with the original service request.

[0089] In some embodiments of the present application, the service request includes service requests such as network registration services and Internet access services. The service request can be determined according to the actual usage scenario and will not be elaborated here.

[0090] Step 112, the user terminal initiates a network service according to the updated service request.

[0091] In the embodiment of the present application, an abnormal network service recovery method is proposed, which can make up for the deficiency that the network service is abnormal due to the lack of parameters in the service request or the modification of network parameters. In this embodiment, by learning the correct network service from the electronic device, the user terminal can have a certain self-repair ability, saving the user's after-sales communication cost and improving the user's network service experience.

[0092] In some embodiments of the present application, the electronic device can be other user terminals or servers.

[0093] The user terminal can send a first request message to the electronic device, calibrate the configuration parameters with calibration in the first request message by using the electronic device, that is, obtain the calibrated configuration parameters from the electronic device, and then update the service request by using the calibrated configuration parameters, so as to initiate a network service according to the updated service request.

[0094] In the above embodiments, automatic iterative update of service requests can be achieved, reducing the probability of network service anomalies and increasing the probability of successful response of network services from network service entities.

[0095] In some embodiments of the present application, as Figure 2 shown, the abnormal network service recovery method includes:

[0096] Step 202, the user terminal broadcasts a second request message, which includes configuration parameters to be calibrated and the first terminal identification information of the user terminal.

[0097] In some embodiments of the present application, broadcasting is a "one-to-all" communication mode between hosts. The network unconditionally replicates and forwards the signal sent by each host, and all hosts can receive the message. In the embodiments of the present application, the user terminal sends a second request message in its communication network, and other terminals or servers in the communication network can receive the second request message.

[0098] In some embodiments of the present application, the communication network is a topological structure constructed by connecting hosts in a wired or wireless manner.

[0099] In some embodiments of the present application, the first terminal identification information is the identity identification number of the user terminal.

[0100] Specifically, for example, the identity identification number, that is, the identity identification code, also known as the serial number or account number, is a relatively unique code in a certain system, equivalent to a kind of "ID card", and in a specific thing, the identity identification number is generally unchanged.

[0101] Step 204, the electronic device receives the second request message broadcast by the user terminal.

[0102] In this embodiment, the user terminal sends a second request message to the communication network where the user terminal is located, and the electronic device in the communication network can receive the second request information sent by the user terminal to determine whether to send a second response message to the electronic device.

[0103] Step 206, the electronic device sends a second response message when the terminal identification information sending condition is met, and the second response message includes the second terminal identification information of the electronic device.

[0104] In this embodiment, the second response message may be the second terminal identification information of the electronic device; or the second response message includes the first terminal identification information of the user terminal and the second terminal identification information of the electronic device.

[0105] For example, in some embodiments of the present application, the first terminal identification information of the user terminal and the second terminal identification information of the electronic device are transmitted in the form of a string. Among them, the first terminal identification information of the user terminal and the second terminal identification information of the electronic device are concatenated together to form a new string for the user terminal to receive.

[0106] Step 208, the user terminal receives the second response message.

[0107] Step 210, the user terminal generates a first request message based on the second terminal identification information and the configuration parameters to be calibrated.

[0108] In this embodiment, the first request message includes the second terminal identification information and the configuration parameters to be calibrated.

[0109] For example, the form of the first request message is "ID11111, 22222", where ID11111 is the second terminal identification information and 22222 is the configuration parameter to be calibrated.

[0110] Step 212, the user terminal sends the first request message to the electronic device. The first request message includes the configuration parameters to be calibrated.

[0111] Step 214, the electronic device receives the first request message sent by the user terminal.

[0112] Step 216, the electronic device sends a first response message to the user terminal.

[0113] Step 218, the user terminal receives the first response message sent by the electronic device. The first response message includes the calibrated configuration parameters.

[0114] In this embodiment, the first response message includes the calibrated configuration parameters, such as "33333", where 33333 is the calibrated configuration parameter of 22222.

[0115] In some embodiments of the present application, the first response message includes the first terminal identification information of the user terminal and the calibrated configuration parameters. For example, the form of the first response message is "ID22222, 33333".

[0116] Step 220, the user terminal updates the service request according to the calibrated configuration parameters.

[0117] For example, before updating the service request, the configuration parameter in the service request is "22222", and after updating, the configuration parameter in the service request is "33333".

[0118] Step 222, the user terminal initiates a network service according to the updated service request.

[0119] Among them, the conditions for sending terminal identity recognition information include at least one of the following: the configuration parameters in the service request used when the electronic device initiates a network service are different from the configuration parameters to be calibrated; the electronic device stores an operation record in which the network service has received a successful response from the network service entity within a preset time period; the electronic device initiates a network service and receives a successful response from the network service entity.

[0120] In some embodiments of the present application, when the network service entity successfully responds, the network service entity will send data to the user terminal to provide network services. If there is missing information or invalid information in the service request sent by the user terminal to the network service entity, at this time, the network service entity will not give a successful response to the service request, such as not sending feedback information to the user terminal or sending information such as service request abnormality to the user terminal.

[0121] In some embodiments of the present application, the operation record records the start time, end time, and data volume of the data sent by the network service entity to the user terminal, etc.

[0122] In this embodiment, the user terminal can find an electronic device that can assist it in updating the service request by broadcasting a second request message, thereby realizing the automatic search of the electronic device, and using the found electronic device to realize the automatic update of the service request, which can make up for the deficiency of network service abnormality caused by missing parameters in the service request or network modified parameters. In this embodiment, the user terminal can have a certain self-repair ability by learning the correct network service from the electronic device, saving the user's after-sales communication cost and improving the user's network service experience.

[0123] Specifically, when the electronic device receives the second request message, it will respond to the second request message. Specifically, it determines whether the conditions for sending terminal identity recognition information are met. When the conditions for sending terminal identity recognition information are met, the second terminal identity recognition information of the electronic device is sent to the user terminal so that communication can be established between the user terminal and the electronic device; when the conditions for sending terminal identity recognition information are not met, the electronic device does not respond to the second request message.

[0124] Among them, the second request message contains the first terminal identity recognition information so that the electronic device can know the terminal that sent the second request message, and thus, when the conditions for sending terminal identity recognition information are met, the second terminal identity recognition information is sent to the user terminal according to the first terminal identity recognition information.

[0125] In some embodiments of the present application, the second request message can be broadcast periodically until the second response message is received.

[0126] For example, the second request message is broadcast every 5 minutes until the second response message is received.

[0127] In some embodiments of the present application, as Figure 3 shown, after the user terminal sends the first request message to the electronic device and before the user terminal receives the first response message sent by the electronic device, it further includes:

[0128] Step 302, when the electronic device does not authorize the user terminal to access the electronic device, the electronic device sends a third response message to the user terminal.

[0129] Wherein, the third response message includes first information, and the first information is used to indicate that the electronic device does not authorize the user terminal to access the electronic device.

[0130] In some embodiments of the present application, the third response message may be a string of characters, and the first information may be a character at a certain position in the string of characters, which is used to indicate that the electronic device does not authorize the user terminal to access the electronic device.

[0131] Specifically, for example, when the character at a certain position in the string of characters is 0, it indicates that the electronic device does not authorize the user terminal to access the electronic device, and when the character at this position is 1, it indicates that the electronic device authorizes the user terminal to access the electronic device.

[0132] Step 304, the user terminal receives the third response message sent by the electronic device.

[0133] Step 306, the user terminal sends a third request message to the electronic device.

[0134] Wherein, the third request message includes request authorization information, and the request authorization information is used to request the electronic device to authorize the user terminal to access the electronic device.

[0135] In some embodiments of the present application, the request authorization information includes, for example, the first terminal identification information and the proof file of the user terminal, so that after receiving the third request message, the electronic device authorizes the user terminal to access the electronic device according to the proof file of the user terminal.

[0136] In some embodiments of the present application, the proof file may be a verification code or the like pre-sent by the electronic device to the user terminal, and its specific form will not be elaborated herein.

[0137] Step 308, the electronic device receives the third request message sent by the user terminal.

[0138] Step 310, the electronic device authorizes the user terminal to access the electronic device and sends a fourth response message to the user terminal.

[0139] In some embodiments of the present application, the manner in which the electronic device authorizes the user terminal to access the electronic device can be selected according to the actual usage scenario. For example, the first terminal identification information can be added to the list of authorized access to the electronic device for the user terminal to access the electronic device. The specific authorization form will not be elaborated here.

[0140] Among them, the fourth response message includes second information, and the second information is used to indicate that the electronic device authorizes the user terminal to access the electronic device.

[0141] In this embodiment, by defining that the fourth response message includes second information, specifically, the fourth response message can be a string of characters, and the second information can be a character at a certain position in the string of characters, which is used to indicate that the electronic device does not authorize the user terminal to access the electronic device.

[0142] In some embodiments of the present application, except for the characters at a certain position, the contents of the other characters in the third response message and the fourth response message are the same.

[0143] Step 312, the user terminal receives the fourth response message sent by the electronic device.

[0144] Step 314, resend the first request message.

[0145] In this embodiment, the electronic device determines whether to authorize the user terminal to access the electronic device, and when the user terminal is not authorized to access the electronic device, the user terminal is verified, so as to improve the security of communication between the user terminal and the electronic device and reduce the probability of information leakage.

[0162] Step 418: The user terminal initiates a Register request again.

[0163] Step 420: The network service provider responds with 200 OK, and the IMS registration is successful.

[0164] Step 422: Initiate a SUBSCRIBE to subscribe to the IMS registration status information.
