Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The terms first and second and the like in the description and in the claims, are used for distinguishing between different objects and not necessarily for describing a particular sequential or chronological order of the objects. For example, the first transmission path and the second transmission path, etc., are used to distinguish between different transmission paths, not to describe a particular order of transmission paths.
The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus.
It should be noted that, in the embodiments of the present invention, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g." in an embodiment should not be taken as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.
In the related art, when the terminal device performs registration of the IP multimedia subsystem (IPMultimediaSubsystem, IMS), if the network device does not reply, the terminal device may apply for registration to the network device again, and if the terminal device does not receive a reply of the network device within 128s, the terminal device may end the registration operation and wait for a period of time to initiate the registration operation again. Therefore, the success rate of IMS network registration of the terminal equipment is low, the terminal equipment needs to wait for a long time and retry, process resources of the terminal equipment are occupied, and the power consumption of the terminal equipment is increased.
It should be noted that IMS is a standard of the next generation network defined by the third generation partnership organization (3rd Generation Partnership Project,3GPP), and is characterized by adopting a session initiation protocol (Session Initiation Protocol, SIP) system, and having no relation to communication and access, and can have various capabilities such as separation of various media service control functions and bearer capabilities, separation of calls and session, separation of applications and services, separation of services and networks, and fusion of mobile networks and internet services.
The IMS has been proposed to conform to the trend of convergence of communication networks. Fig. 1 is a schematic diagram of an IMS network system for implementing an IMS network registration method according to an embodiment of the present invention, where the IMS network system mainly includes: the User Equipment 11 (UE), the proxy call session control function 12 (Proxy call session control Function, PCSCF), the query call session control function 13 (Interrogating call session control Function, ICSCF), the serving call session control function 14 (Serving call session control Function, SCSCF), and the home subscriber server 15 (Home subscriber Server, HSS). The data transmission between the functional entities may be represented by arrows in fig. 1.
Wherein the PCSCF is used as a proxy of the UE and is used for forwarding the request and the response between the UE and the SCSCF. The SCSCF is a home service entity of the UE and is used for providing functions such as service logic, authority control and the like for the UE. The HSS is used for storing information such as registration information of the user and customized service.
It should be noted that, the connection manner between UE, PCSCF, ICSCF, SCSCF and HSS in fig. 1 may be a wired connection or a wireless connection, which is not limited by the embodiment of the present invention.
Wherein the IMS network architecture may be part of a core network.
When a user wants to realize communication and internet surfing at the same time when using the UE, the UE is required to register an IMS network, and the specific flow is as follows: firstly, sending a session initiation protocol registration (Session Initiation Protocol REGISTER, SIP REGISTER) request to the PCSCF; the PCSCF processes the SIP REGISTER request and sends SIP REGISTER a request to the selected ICSCF; the ICSCF issues a server assignment request (Server Assignment Request, SAR) message to the HSS to query the address of the SCSCF; the HSS selects one SCSCF and sends the address of the selected SCSCF to the ICSCF through a server assignment response (Server Assignment Answer, SAA) message; the ICSCF forwards SIP REGISTER requests to the selected SCSCF; the SCSCF may send corresponding response information to the UE according to the attribute information of the UE.
The SIP REGISTER request may include: the device identifier of the terminal device, the network identifier of the terminal device, the SIM card identifier of the terminal device, and the operator identifier supported by the terminal device, so that when the ICSCF queries the HSS about the address of the SCSCF, the HSS can select an appropriate SCSCF for the terminal device according to the relevant information of the terminal device in the SIP REGISTER request.
As shown in fig. 2, a flowchart of IMS network registration by a UE may include:
201. a registration request is sent, a first timer is started, and counting begins.
A first timer (timer-1) is started after the UE sends SIP REGISTER a request to the PCSCF, and counted from n=1, N being the number of times the UE sends SIP REGISTER a request to the PCSCF, and then the UE waits for a reply from the PCSCF,
202. it is detected whether the network device replies.
If the network device replies, the UE proceeds to step 203; if the network device does not reply, the UE proceeds to step 204.
203. And starting a registration process.
204. It is detected whether the first timer has timed out.
If the first timer times out, the UE performs 205; if the first timer does not time out, the UE proceeds to step 206.
205. A second timer is started.
If the UE does not receive a reply from the PCSCF and timer-1 has timed out, the UE starts a second timer (timer-2) to start counting and after timer-2 times out, sends SIP REGISTER a request again to the PCSCF, starts timer-1 and starts counting from n=1.
206. Resend the registration request.
If the UE does not receive a reply from the PCSCF and timer-1 does not time out, the UE will resend SIP REGISTER the request to the PCSCF, where n=2, where the time interval from the first SIP REGISTER request to resending SIP REGISTER the request to the PCSCF is T, t=min (max time, base time 2 N-1 ) The maxtime and basetime are recorded according to the historical IMS network registration record of the terminal equipment or the IMS network registration record of other equipmentThe interval duration of the transmission of the registration request.
In order to avoid that the UE does not receive the reply from the PCSCF and resends SIP REGISTER the request to the PCSCF multiple times, the terminal device will set a fixed duration, which is currently generally specified by the operator to be 128s. When the UE does not receive the reply from the PCSCF within the fixed duration, the UE stops not performing IMS network registration any more. Thus, the terminal device needs to wait and retry for a long time, and occupies the process resources of the terminal device.
In order to solve the above-mentioned problems, the embodiments of the present invention provide an IMS network registration method and a terminal device, where the terminal device may first send a first registration request message for applying for IMS network registration to the network device through a first transmission path, and if a registration response message for the first registration request message sent by the network device is not received, it may be stated that the transmission path is faulty, then the terminal device may switch the transmission path, send the first registration request message to the network device through a second transmission path, where the first transmission path is different from the PCSCF in the second transmission path. According to the scheme, the terminal equipment can actively switch the transmission path, and initiate IMS network registration to the network equipment through the new transmission path, so that the success rate of IMS network registration is greatly improved, the situation that IMS network registration is repeatedly initiated to the network equipment through the same transmission path is avoided, and the total duration of IMS network registration of the terminal equipment is effectively shortened.

Example 1
As shown in fig. 3, an embodiment of the present invention provides an IMS network registration method, which may include the following steps:
301. a first registration request message is sent to the network device over a first transmission path.
In the embodiment of the invention, the terminal equipment can send the first registration request message to the network equipment through the first transmission path.
Alternatively, the first transmission path may include: the network device may configure a plurality of transmission paths to the terminal device in advance, where at least one of the transmission paths has different functional entities, so that when one transmission path fails, the terminal device may send a first registration request message to the network device through another transmission path.
In the embodiment of the present invention, the PCSCF in the first transmission path is different from that in the second transmission path.
Alternatively, the ICSCF and SCSCF in the first transmission path and the second transmission path may be different, or may be the same, which is not limited by the embodiment of the present invention.
The first registration request message is used for applying for IMS network registration to the network equipment.
Optionally, the first registration request message may include: device identification of the terminal device, network identification of the terminal device, SIM card identification of the terminal device, operator identification supported by the terminal device, and the like.
Alternatively, when the terminal device sends the first registration request message to the network device through the first transmission path, the timer-1 may be started to start timing.
302. And if the registration response message for the first registration request message sent by the network equipment is not received, sending the first registration request message to the network equipment through a second transmission path.
In the embodiment of the present invention, if the terminal device does not receive the registration response message for the first registration request message sent by the network device, it may be stated that the transmission path between the terminal device and the network device is faulty, and then the terminal device may send the first registration request message to the network device through the second transmission path.
The registration request message is used for indicating that the terminal equipment does not obtain an IMS network registration authorization credential or that the terminal equipment is successfully registered in an IMS network.
Alternatively, when the transmission path of the terminal device sending the first registration request message to the network device is switched from the first transmission path to the second transmission path, timer-1 may continue to time.
Alternatively, the terminal device may disconnect the transmission control protocol (TransmissionControlProtocol, TCP) first when switching the transmission path. When the second transmission path is queried, the TCP connection is restarted and switched from the first transmission path to the second transmission path.
Optionally, if the registration response message sent by the network device for the first registration request message is not received, the first registration request message is sent to the network device through the second transmission path, which may include, but is not limited to, the following embodiments:
in one embodiment: before the registration response message for the first registration request message sent by the network device is not received, before the first registration request message is sent to the network device through the second transmission path, if the registration response message for the first registration request message sent by the network device is not received within the second preset duration, the first registration request message is sent to the network device again through the first transmission path.
In the embodiment of the present invention, if the terminal device does not receive the registration response message for the first registration request message sent by the network device within the second preset duration, it may be indicated that the network device or the first transmission path is faulty, or the current network is busy and cannot respond to the IMS network registration request of the terminal device, and then the terminal device may send the first registration request message to the network device again through the first transmission path.
Optionally, the time interval between two adjacent terminal devices sending the first registration request message to the network device is a second preset duration, where the second preset duration may be a power of 2, for example: 8s,4s,2s, etc.
In this alternative embodiment, when the terminal device does not receive the registration response message of the network device, possibly because the current network is busy and unresponsive or the transmission path fails, the terminal device may send the first registration request message again, so as to avoid the situation that the IMS network registration cannot be successfully performed due to the temporary failure.
In another embodiment: and if the registration response message for the first registration request message sent by the network equipment is not received within the first preset duration, sending the first registration request message to the network equipment through the second transmission path.
In the embodiment of the invention, the terminal device may set a first preset duration, and in the first preset duration, the terminal device may wait for a registration response message sent by the network device for the first registration request message all the time.
For example, assuming that the terminal device sets the first preset duration to 64s, if the terminal device does not receive the registration response message for the first registration request message sent by the network device within the 64s, the terminal device may send the first registration request message to the network device through the second transmission path.
In this alternative embodiment, the terminal device may limit the duration of the registration response message sent by the waiting network device, if the network device does not reply within the first preset duration, it may be that the current transmission path fails, and the terminal device may switch the transmission path and send the first registration request message to the network device through the second transmission path, so that the situation that the terminal device waits for the reply of the network device for a long time can be avoided, and the duration of the terminal device performing IMS network registration is shortened.
In another embodiment: if the number of times of sending the first registration request message reaches the preset number of times and the registration response message for the first registration request message sent by the network device is not received, the first registration request message is sent to the network device through the second transmission path.
In the embodiment of the invention, the terminal device can set a preset number of times, and when the number of times that the terminal device sends the first registration request message to the network device reaches the preset number of times and the terminal device does not receive the registration response message for the first registration request message sent by the network device, the terminal device can send the first registration request message to the network device through the second transmission path.
For example, if the preset number of times is 5, within the second preset duration, when the terminal device does not receive the registration response message for the first registration request message sent by the network device, the first registration request message is sent to the network device again through the first transmission path; when the number of times the terminal device transmits the first registration request message to the network device reaches the 5 th time, and after the fifth time of transmitting the first registration request message, the terminal device does not receive the registration response message for the first registration request message transmitted by the network device, then the terminal device may switch the transmission path, and transmit the first registration request message to the network device through the second transmission path.
In this alternative embodiment, the terminal device may limit the number of times of sending the first registration request message to the network device, if the number of times of sending the first registration request message reaches the preset number of times, it may be that the current transmission path fails, and the terminal device may switch the transmission path, and send the first registration request message to the network device through the second transmission path, so that the situation that the terminal device applies for registration for multiple times without reply can be avoided, and the duration of the terminal device for performing IMS network registration is shortened.
In another embodiment: and if the number of times of sending the first registration request message reaches the preset number of times within the first preset duration and the registration response message for the first registration request message sent by the network equipment is not received, sending the first registration request message to the network equipment through a second transmission path.
In the embodiment of the invention, the terminal equipment can set a first preset time length and preset times, and the terminal equipment can repeatedly send the first registration request message to the network equipment for a plurality of times within the first preset time length. When the number of times that the terminal device sends the first registration request message to the network device reaches the preset number of times within the first preset duration, and the terminal device does not receive the registration response message for the first registration request message sent by the network device, the terminal device can send the first registration request message to the network device through the second transmission path.
For example, assume that the terminal device sets the first preset duration to 64s and the preset number of times to 5.

Alternatively, the foregoing embodiments may be split and combined separately to obtain more embodiments, which are not limited to the embodiments of the present invention.
Alternatively, this embodiment may be combined with any of the other embodiments, respectively, to obtain further embodiments.
For example, if a registration response message for the first registration request message sent by the network device is not received within a first preset duration, detecting whether an idle second transmission path exists; and if the idle second transmission path exists, sending a first registration request message to the network equipment through the second transmission path.
In this alternative embodiment, the terminal device may set a first preset duration, and in the first preset duration, the terminal device may repeat sending the first registration request message to the network device multiple times. If the terminal equipment does not receive the registration response message for the first registration request message sent by the network equipment within the first preset duration, the terminal equipment can firstly detect whether an idle second transmission path exists; if there is an idle second transmission path, the terminal device may switch the transmission path and send a first registration request message to the network device via the second transmission path.
Through the optional embodiment, when the duration reaches the first preset duration, if an idle second transmission path exists, the terminal equipment switches the transmission path, and sends the first registration request message to the network equipment through the second transmission path, so that the condition that the terminal equipment waits for the reply of the network equipment for a long time can be avoided, and the duration of IMS network registration by the terminal equipment is shortened.
Optionally, if there is no idle second transmission path, after a third preset duration, a first registration request message is sent to the network device through the first transmission path.
It should be noted that if the terminal device detects that there is no idle second transmission path, other transmission paths may be occupied, or the network device configures only one transmission path for the terminal device in advance, then the terminal device may end the current IMS network registration procedure, and after a third preset period of time, start the IMS network registration procedure again, and send a first registration request message to the network device through the first transmission path.
Optionally, the terminal device may further set a first time threshold, and when the duration of sending the first registration request message to the network device by the terminal device reaches the first time threshold, the IMS network registration process is ended, and after a third preset duration, the IMS network registration process is started again, and the first registration request message is sent to the network device through the first transmission path.
The time period for the terminal device to send the first registration request message to the network device includes the time period for the terminal device to send the first registration request message to the network device through the first transmission path, the time period for the terminal device to send the first registration request message to the network device through the second transmission path, and the time period for the terminal device to send the first registration request message to the network device through other transmission paths.
For example, assume that the terminal device sets a first time length threshold of 96s, a first preset time length of 64s, and a third preset time length of 90s. If the terminal device does not receive the registration response message for the first registration request message sent by the network device after 64s, the terminal device can send the first registration request message to the network device through the second transmission path, the terminal device can continue timing from 64s, when the time reaches 96s, the terminal device does not receive the registration response message for the first registration request message sent by the network device, the terminal device can end the IMS network registration process, and after 90s, the IMS network registration process is started again, and the first registration request message is sent to the network device through the first transmission path.
Optionally, after sending the first registration request message to the network device through the second transmission path, the method may further include: and receiving a registration response message sent by the network equipment.
In the embodiment of the present invention, after the terminal device sends the first registration request message to the network device through the second transmission path, the terminal device may receive the registration response message sent by the network device.
Optionally, the terminal device receives the registration response message sent by the network device, which may include, but is not limited to, the following embodiments:
in one embodiment: and receiving a first registration response message sent by the network equipment, wherein the first registration response message can be specifically used for indicating the network equipment to perform IMS network registration by unauthorized terminal equipment.
Wherein the first registration response message may include: authorization verification information of the terminal device.
Alternatively, the first registration response message may specifically be "401 unouthorized".
Optionally, when the terminal device initially sends the first registration request message to the network device, the network device does not detect the authorization information of the terminal device, so the network device generally sends the first registration response message to the terminal device, which is used for prompting the network device that the terminal device is not authorized to perform IMS network registration, and sending authorization verification information to the terminal device.
Optionally, the authorization verification information sent by the network device to the terminal device may include: authentication information and a random code of the terminal device.
Further, after receiving the first registration response message sent by the network device, the terminal device may send a second registration request message to the network device.
Wherein the second registration request message is used to apply for IMS network registration to the network device again. The second registration request message may include: authorization verification information of the terminal device.
Optionally, after receiving the authorization verification information sent by the network device, the terminal device may calculate the verification information and the random code of the terminal device to obtain a calculation result, and send the calculation result to the network device as the authorization verification information.
In another embodiment: and receiving a second registration response message sent by the network equipment, wherein the second registration response message can be specifically used for indicating that the IMS network registration of the terminal equipment is successful.
It should be noted that, after the terminal device sends the first registration request message to the network device through the second transmission path, the network device may detect whether the first registration request message has correct authorization verification information, and if so, send a second registration response message to the terminal device, where the second registration response message is used to indicate that the terminal device IMS network registration is successful. If the authorization verification information is wrong, a third registration response message is sent to the terminal device, and is used for indicating that the authorization verification information of the terminal device is wrong.
Alternatively, the second registration response message may specifically be "200OK".
Illustratively, it is assumed that the authorization verification information sent by the network device to the terminal device includes: random number 312451, and calculation questions: 12*23. The terminal device, after receiving the first registration response message, may calculate the question: 12×23 performs calculation to obtain a calculation result of 276, then the terminal device may send the random number 312451 and the calculation result 276 to the network device again, after receiving the authorization verification information, the network device may perform verification, the random number 312451 is consistent with the random number sent by the network device, and 12×23=276 may indicate that the authorization verification information sent by the terminal device is correct, and then the network device may send "200OK" to the terminal device.
Optionally, before the terminal device sends the first registration request message to the network device through the first transmission path, the method may further include: detecting whether the network equipment is authorized to the terminal equipment, and if the network equipment is authorized to the terminal equipment, sending a first registration request message to the network equipment through a first transmission path; if the network equipment does not authorize the terminal equipment, an authorization request message is sent to the network equipment, wherein the authorization request message is used for requesting the network equipment to authorize the terminal equipment to perform IMS network registration.
It should be noted that, before the terminal device sends the first registration request message to the network device, if the terminal device is not authorized by the network device, it is indicated that the network device does not perform IMS network registration authorization on the terminal device, and the terminal device may first apply authorization to the network device.
In this alternative embodiment, the terminal device may actively detect whether the terminal device is authorized, and if the terminal device is not authorized, the terminal device may actively apply for authorization to the network device, so that the initiative of the terminal device may be improved, the time for the terminal device to perform IMS network registration may be shortened, and the IMS network registration efficiency may be improved.
Optionally, after sending the first registration request message to the network device through the second transmission path, the method may further include: and outputting a prompt message if the abnormal prompt message sent by the network equipment is received.
The prompting message is used for prompting the user that the current network equipment is abnormal and can not be registered.
It should be noted that if the network device fails, the terminal device cannot register the IMS network successfully, and at this time, the network device may send an abnormal prompt message to the terminal device to prompt the user that the network fails currently, and then the terminal device may wait for a period of time, start the IMS network registration procedure again, and send the first registration request message to the network device again.
The embodiment of the invention provides an IMS network registration method, wherein a terminal device can firstly send a first registration request message for applying IMS network registration to a network device through a first transmission path, if a registration response message aiming at the first registration request message sent by the network device is not received, the terminal device can indicate that the transmission path has a fault, the terminal device can switch the transmission path, and send the first registration request message to the network device through a second transmission path, wherein the first transmission path is different from PCSCF in the second transmission path. According to the scheme, the terminal equipment can actively switch the transmission path, and initiate IMS network registration to the network equipment through the new transmission path, so that the success rate of IMS network registration is greatly improved, the situation that IMS network registration is repeatedly initiated to the network equipment through the same transmission path is avoided, and the total duration of IMS network registration of the terminal equipment is effectively shortened.
Example two
As shown in fig. 4, an embodiment of the present invention provides an IMS network registration method, which may further include the following steps:
401. a first registration request message is sent to the network device over a first transmission path.
In the embodiment of the invention, when the terminal equipment sends the first registration request message to the network equipment through the first transmission path, if the registration response message sent by the network equipment is not received, the first registration request message is sent to the network equipment through the first transmission path again.
Optionally, when the first registration request message is repeatedly sent to the network device for a plurality of times, the former request time interval is greater than or equal to the latter request time interval; the request time interval is a time interval between two adjacent times of sending the first registration request message to the network device by the terminal device.
As shown in fig. 4, the time interval between the first time of transmitting the first registration request message to the network device through the first transmission path and the second time of transmitting the first registration request message to the network device through the first transmission path is T 1 The time interval between the second time of sending the first registration request message to the network device through the first transmission path and the third time of sending the first registration request message to the network device through the first transmission path is T 2 Until the time interval between the last time of sending the first registration request message to the network equipment through the first transmission path and the last time of sending the first registration request message to the network equipment through the first transmission path is T n 。
Alternatively, T 1 ≥T 2 ≥…≥T n T1 may be 8s, T2 may be 4s, T3 may be 2s, T4 may be 2s.
Furthermore, the terminal device may further calculate a second preset duration according to a preset formula.
Wherein the preset formula is t=max (min time, max time×2 -N ) The method comprises the steps of carrying out a first treatment on the surface of the T is a second preset duration, and N is the number of times that the terminal equipment sends the first registration request message to the network equipment again.
It should be noted that, N is the number of times that the terminal device sends the first registration request message to the network device again, that is, the number of times that the terminal device sends the first registration request message to the network device for the first time does not count in. The minimum time and the maxtime are set by the terminal equipment according to the retransmission interval duration in the historical IMS network registration record or the IMS network registration record of other equipment, and the first duration parameter is smaller than the second duration parameter.
Alternatively, the total duration of the first registration request message sent to the network device via the same transmission path may be less than 128s, i.e. T 1 +T 2 +…+T n ＜128s。
It should be noted that, in the prior art, the operator generally specifies that the terminal device does not receive the registration response message for the first registration request message sent by the network device within 128s, then the terminal device may stop not performing IMS network registration any more, and the maximum time interval between sending the first registration request message to the network device any two times is 16s.
In the embodiment of the invention, in order to ensure that the total duration of applying for the IMS network registration through the same transmission path is less than 128s, T can be less than 16s and is the power of 2, then maxtime can be less than or equal to 16s, and the minimum time can be less than 16s.
Illustratively, assume a mintime of 2s and a maxtime of 16s. Then t=max (2, 16×2 -N ) As shown in fig. 4, when n=1, T 1 =max (2, 8) =8s; when n=2, T 2 =max (2, 4) =4s; when n=3, T 3 =max (2, 2) =2s; when n=4, T 4 =max (2, 1) =2s; it can be seen that when the terminal device repeatedly sends the first registration request message to the network device for the first time, i.e. sends the first registration request message to the network device for the second time, the time interval between the first time of sending the first registration request message to the network device is 8s, i.e. T 1 =8s; when the terminal equipment repeatedly sends the first registration request message to the network equipment for the second time, namely, sends the first registration request message to the network equipment for the third time, the time interval between the second time of sending the first registration request message to the network equipment is 4s, namely, T 2 =4s; when the terminal equipment repeatedly sends the first registration request message to the network equipment for the third time, namely, the first registration request message is sent to the network equipment for the fourth time, the time interval between the third time of sending the first registration request message to the network equipment is 2s, namely, T 3 =2s; when the terminal device repeatedly sends the first registration request message to the network device for the fourth time, namely, the first registration request message is sent to the network device for the fifth time, the time interval between the fourth time of sending the first registration request message to the network device is 2s, namely, T 4 ＝2s。
Through the alternative implementation manner, when the first registration request message is repeatedly sent to the network device for multiple times, the former request time interval is greater than or equal to the latter request time interval, so that if the registration response message of the network device is not received when the first registration request message is sent to the network device for the first time, it can be stated that the network device or the first transmission path is faulty, or the current network is busy and cannot respond to the IMS network registration request of the terminal device, and when the first registration request message is sent to the network device again, the waiting time between sending the first registration request message for two times can be shortened, so that the total time of the whole IMS network registration process can be shortened, and the loss of process resources of the terminal device can be reduced.
402. It is detected whether an idle second transmission path exists.
In the embodiment of the present invention, the network device may configure a plurality of transmission paths to the terminal device in advance, where PCSCF in each transmission path is different, and when the terminal device cannot receive the registration response message for the first registration request message sent by the network device through the first transmission path, possibly because the current first transmission path fails, the terminal device may detect whether other second transmission paths in an idle state exist.
403. And if the idle second transmission path exists, sending a first registration request message to the network equipment through the second transmission path.
Optionally, in the embodiment of the present invention, if there is no idle second transmission path, after a third preset duration, the terminal device may send a first registration request message to the network device through the first transmission path.
It should be noted that if the terminal device detects that there is no idle second transmission path, then other transmission paths may be occupied, or the network device configures only one transmission path to the terminal device in advance, then the terminal device may suspend the IMS network registration procedure; and starting the timer-2, and after the timer-2 times out, sending a first registration request message to the network equipment through the first transmission path again, restarting the timer-1, and starting counting.
The embodiment of the invention provides an IMS network registration method, wherein a terminal device can firstly send a first registration request message for applying IMS network registration to a network device through a first transmission path, if a registration response message aiming at the first registration request message and sent by the network device is not received, which is possibly that a current first transmission path has faults, the terminal device can detect whether an idle second transmission path exists, if the idle second transmission path exists, the first registration request message is sent to the network device through the second transmission path, and the first transmission path is different from PCSCF in the second transmission path. According to the scheme, the terminal equipment can actively switch the transmission path, and initiate IMS network registration to the network equipment through the new transmission path, so that the success rate of IMS network registration is greatly improved, the situation that IMS network registration is repeatedly initiated to the network equipment through the same transmission path is avoided, and the total duration of IMS network registration of the terminal equipment is effectively shortened.
