Currently, most operators support both VoLTE (Voice over LTE) and VoWiFi (Voice over Wi-Fi) access to their IMS networks. For an electronic device supporting both VoLTE and VoWiFi, there is usually a call preference setting option, if Wi-Fi is set to be preferred, the electronic device preferably registers in volga when connecting to an LTE network and a Wi-Fi network, and if Cellular is set to be preferred, the electronic device preferably registers in VoLTE.
In the related art, in the normal VoWiFi registration process, when IPSec tunnel is successfully established, the ePDG network starts a DPD (Dead Peer Detection) timer, and after the timer expires, the ePDG sends an IKE message to the electronic device to detect whether the electronic device is Alive (that is, whether the connection between the electronic device and the ePDG is Alive is indicated), and if an IKE response message from the electronic device is received, the electronic device is Alive (Alive); if not, the electronic device is not alive (Dead).
However, under the condition that the network side device does not know that the electronic device has been Dead, if the network side device receives the IKE or IPSec connection establishment request message from the electronic device again, the network side device does not perform an operation of responding to the new request or rejecting the new request, and at this time, the electronic device frequently triggers an invalid VoWiFi registration operation. Frequent and inefficient VoWiFi registration operations may cause wasted power consumption on the terminal side and the network side.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application are capable of operation in sequences other than those illustrated or described herein, and that the terms "first," "second," etc. are generally used in a generic sense and do not limit the number of terms, e.g., a first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The network access method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings, taking an electronic device as a terminal device as an example, through a specific embodiment and an application scenario thereof.
The embodiment of the application provides an IMS registration protection method aiming at disconnection of Wi-Fi in a VoWiFi registration state.
In the related art, during the VoWiFi normal registration process, a situation of abrupt WiFi disconnection (such as manually turning on an offline mode, etc.) inevitably occurs, and such an operation is common, before the DPD timer of the ePDG server times out, the ePDG does not know that the terminal device has released the IKE connection previously established with the ePDG, that is, the ePDG still retains the IKE connection context information of the VoWiFi registration of the previous terminal device. During the period, if the preference set by the terminal device is VoWiFi priority and the operation of connecting to the Wi-Fi or LTE network is retriggered (such as turning off offline, etc.), the terminal device may preferably perform VoWiFi registration and reinitiate the IKE connection establishment procedure to the ePDG, but at this time, the ePDG may not respond to the terminal device or reject the terminal device, thereby causing an IKE establishment failure.
Generally, after IKE fails, the terminal device will Retry at a certain time interval, and it is foreseeable that this Retry procedure may fail until a DPD timer fails (Expire), and the RAT for IMS registration is not switched to LTE until the entire Retry procedure is completed, and then VoLTE is registered; this not only affects the registration performance of IMS (the user may feel that VoLTE registration is slow), but also introduces unnecessary power consumption, seriously affecting the user experience.
According to the network access method and the network access device, under the condition that the terminal equipment is registered in the VoWiFi network, if the disconnection of the VoWiFi network is detected, the network access setting information of the terminal equipment is obtained, and if the network access setting information indicates that the terminal equipment is preferentially accessed to the VoWiFi network, whether the connection establishment process of the VoWiFi network is triggered or not is determined according to the connection context information of the VoWiFi network before the network side equipment is released currently. Therefore, the terminal equipment is guaranteed to be disconnected and reconnected with the Wi-Fi in any scene under the VoWiFi registration state, the user can smoothly register the IMS service, the registration performance of the IMS is improved, meanwhile, the problem of power consumption of the terminal side and the network side caused by frequent and invalid VoWiFi registration operation is avoided, and resources of the terminal side and the network side are saved.
The embodiment of the application provides a network access method, which can be executed by terminal equipment. In other words, the network access method may be performed by software or hardware installed in the terminal device. As shown in fig. 1, a network access method provided in an embodiment of the present application may include the following steps:
step 101: under the condition that the terminal equipment is registered to the VoWiFi network, if the disconnection of the VoWiFi network is detected, the network access setting information of the terminal equipment is acquired.
The network access setting information of the terminal device is used for indicating whether the preference setting of the terminal device is set to be preferentially accessed to the VoWiFi network.
Step 102: and if the network access setting information indicates that the terminal equipment preferentially accesses the VoWiFi network, determining whether to trigger a connection establishment process of the VoWiFi network according to the connection context information of the VoWiFi network before the network side equipment is released currently.
In this embodiment of the present application, the terminal device may determine whether to register VoWiFi or register VoLTE or keep in VoLTE after connecting Wi-Fi by reading operator IPSec Tunnel connection policy information, previous IPSec Tunnel release information, DPD timer explicit information, and VoLTE registration status information in a scenario that the terminal device disconnects and reconnects a VoWiFi network according to its own IMS preference setting (i.e., the network access setting information) so as to determine whether to select to register VoWiFi or register VoLTE or keep in VoLTE after connecting Wi-Fi by reading operator IPSec Tunnel connection policy information, previous IPSec Tunnel release information, DPD timer explicit information, and VoLTE registration status information.
Optionally, in this embodiment of the present application, the step 102 may include the following step 102a or step 102b:
step 102a: and if the connection context information of the VoWiFi network before the network side equipment is released currently is determined, triggering a connection establishment process of the VoWiFi network.
Step 102b: if it is determined that the network side device does not release the connection context information currently, if the terminal device is registered to a VoLTE network currently, the terminal device continues to reside in the VoLTE network, and if the terminal device is not registered to the VoLTE network currently, a connection establishment process of the VoLTE network is triggered.
Further optionally, in this embodiment of the present application, before the step 102a, the method may further include the following step 102a1:
step 102a1: and sending a connection establishment request to the network side equipment, wherein the connection establishment request is used for indicating the connection context information of the VoWiFi network before the network side equipment is released.
Further, based on the step 102a1, the step 102a may include the following steps:
step 102a2: and under the condition that the connection establishment request is successfully sent, triggering a connection establishment process of the VoWiFi network.
Further optionally, in this embodiment of the present application, the step 102a may include the following steps:
102a3: and if detecting that the terminal equipment does not send a connection establishment request to the network side equipment, triggering a connection establishment flow of the VoWiFi network when a first timer is timed out.
The time length of the first timer is greater than or equal to the time length required by the network side equipment to release the connection context information.
Optionally, in this embodiment of the present application, since the operator in some countries is before DPD Timer Expire and does not know the terminal device Dead, if the IKE or IPSec connection establishment request message from the terminal device is received again, since the context information of the previous connection stored in the network side device is not released, the network side device may not respond to the new request or reject the new request, and thus, the VoWiFi service access of the terminal device may be abnormal.
Illustratively, in view of the above problem, when the network used by the electronic device is a network provided by the above operator, the step 102 may include the following step 102c:
step 102c: and if the network access setting information indicates that the terminal equipment preferentially accesses the VoWiFi network and the operator information of the terminal equipment contains the target mark, determining whether to trigger the connection establishment process of the VoWiFi network according to the connection context information of the VoWiFi network before the network side equipment is released currently.
Wherein the target mark is used for indicating: when the VoWiFi network is re-registered, the network side device needs to release the previous connection context information of the VoWiFi network.
Illustratively, by marking the operator information of part of operators to indicate that a terminal device using a network provided by the operator needs to make policy selection when re-registering the VoWiFi network next time, that is, to ensure that "new registration needs to ensure that old connection is released", thereby ensuring the registration performance of the IMS, and avoiding the problem of power consumption of the terminal side and the network side caused by frequent and invalid VoWiFi registration operations.
Optionally, in this embodiment of the present application, the terminal device may decide whether to register VoWiFi or register VoLTE or remain in VoLTE after connecting Wi-Fi through any of the following policies.
Firstly, the method comprises the following steps: if the IMS phone preference setting (i.e. the network access setting Information) of the terminal device is VoWiFi-first and policy selection is required, but the terminal device has initiated an IPSec Tunnel Release request (e.g. IMS De-Register and IKE Information Release request) to a network side device (e.g. ePDG) and the message is successfully sent, directly triggering an IKE connection procedure of VoWiFi to establish an IPSec Tunnel according to the configuration requirement of the current VoWiFi-first, and then registering VoWiFi.
Secondly, the method comprises the following steps: if the IMS telephone preference setting of the terminal equipment is VoWiFi priority and policy selection is required, and the terminal equipment does not initiate an IPSec Tunnel Release request to the ePDG, but the DPD Timer already indicates that the ePDG has also released IKE connection context information of the previous VoWiFi, the terminal equipment directly triggers an IKE connection process of the VoWiFi to establish the IPSec Tunnel according to the configuration requirement of the current VoWiFi priority, and then registers the VoWiFi.
Thirdly, the method comprises the following steps: if the terminal device satisfies the following 4 conditions:
condition 1: IMS phone preference setting VoWiFi preferred;
condition 2: strategy selection is needed;
condition 3: the terminal equipment does not initiate an IPSec tunnel Release request to the ePDG;
condition 4: DPD Timer has not yet Expired.
If the terminal equipment is registered in the VoLTE currently, the terminal equipment is not required to be operated, and the terminal equipment is kept in the VoLTE registered state continuously. On the contrary, if the terminal device does not register VoLTE, the current Wi-Fi preference setting is directly ignored, and a Cellular (Cellular) preferred mode is selected to register the IMS, that is, registration of VoLTE is triggered.
It should be noted that, after DPD Timer Expired, the terminal device detects that the IMS preference is set to Wi-Fi priority and registers in VoLTE, and then initiates IPSec Tunnel establishment and a registration request of VoWiFi to the network again, and the VoLTE is switched to the VoWiFi again.
According to the network access method provided by the embodiment of the application, under the condition that the terminal equipment is registered in the VoWiFi network, if the disconnection of the VoWiFi network is detected, the network access setting information of the terminal equipment is obtained, and if the network access setting information indicates that the terminal equipment is preferentially accessed to the VoWiFi network, whether the connection establishment process of the VoWiFi network is triggered or not is determined according to the connection context information of the VoWiFi network before the network side equipment is released currently. Therefore, the terminal equipment is guaranteed to be disconnected and then connected with any scene of Wi-Fi in the VoWiFi registration state, the user can smoothly register the IMS service, the registration performance of the IMS is improved, the problem of power consumption of the terminal side and the network side caused by frequent and invalid VoWiFi registration operation is avoided, and resources of the terminal side and the network side are saved.
The scheme provided by the embodiment of the present application will be exemplarily explained by 4 embodiments.
Example 1:
the method and the device mainly aim at a scene that both VoLTE and VoWiFi switches of the terminal equipment are turned on, and realize the process of optimizing IMS registration logic under the scene. Specifically, assuming that the network side device is an ePDG, a specific implementation process of the technical solution provided in the embodiment of the present application is as follows:
step S1: and the terminal equipment triggers the Wi-Fi connection operation.
Step S2: reading IMS phone preference settings of the current terminal device (i.e., the above network access setting information), reading policy selection information (example 2 described below), DPD Timer status information (example 3 described below), IPSec Tunnel status information (example 4 described below), and VoLTE registration information from a Database (Database), and combining these information to decide whether to register VoWiFi or to register VoLTE or to keep VoLTE after Wi-Fi connection.
And step S3: and if the IMS telephone preference setting of the terminal equipment is not VoWiFi priority, any operation is not needed, and the method can be continuously executed according to the existing flow of the terminal equipment.
And step S4: if the IMS telephone preference setting of the terminal equipment is VoWiFi priority, but policy selection is not needed, the IKE connection process of the VoWiFi is triggered to establish the IPSec Tunnel directly according to the configuration requirement of the current VoWiFi priority, and then the VoWiFi is registered.
Step S5: if the IMS telephone preference setting of the terminal equipment is VoWiFi priority and policy selection is needed, but the terminal equipment already initiates an IPSec Tunnel Release request to the ePDG and successfully sends out the message, an IKE connection process of the VoWiFi is triggered to establish the IPSec Tunnel directly according to the configuration requirement of the current VoWiFi priority, and then the VoWiFi is registered.
Step S6: if the IMS phone preference setting of the terminal device is VoWiFi priority and policy selection is required, and the terminal device does not initiate an IPSec Tunnel Release request to the ePDG, but the DPD Timer has failed (Expired), it indicates that the ePDG has also released the IKE connection context information of the previous VoWiFi, so the IKE connection procedure of VoWiFi is triggered to establish the IPSec Tunnel directly according to the configuration requirement of the current VoWiFi priority, and then the VoWiFi is registered.
Step S7: if the terminal device satisfies the following 4 conditions:
condition 1: IMS phone preference setting is Wi-Fi first;
condition 2: strategy selection is needed;
condition 3: the terminal equipment does not initiate an IPSec tunnel Release request to the ePDG;
condition 4: the DPD Timer has not been Expired.
If the terminal equipment is registered in the VoLTE currently, the terminal equipment is not required to be operated, and the terminal equipment is continuously kept registered in the VoLTE. On the contrary, if the terminal device does not register VoLTE, the current Wi-Fi preference setting is directly ignored, and a Cellular (Cellular) preferred mode is selected to register the IMS, that is, registration of VoLTE is triggered.
Example 2:
the method and the device mainly aim at a scene that both VoLTE and VoWiFi switches of the terminal equipment are turned on, and realize the process of optimizing IMS registration logic under the scene. Specifically, assuming that the network side device is an ePDG, a specific implementation process of the technical scheme provided in the embodiment of the present application is as follows:
step S21: and the terminal equipment triggers the Wi-Fi disconnection operation.
Step S22: if the terminal equipment is not registered in the VoWiFi service, no operation is needed, and the existing process of the terminal can be carried out.
Step S23: and if the terminal equipment is registered in the VoWiFi service, inquiring IPSec connection strategy of the current operator.
For example, some operators currently known do not accept or reject a new IKE connection establishment request initiated by a terminal device until the previous IKE connection context information of the terminal device is not released. For these operator policies, they can be obtained to the operator or the terminal device itself gets known through some tests, and then the relevant operator information is saved in Database or List for inquiry.
Step S24: and if the new registration of the current operator does not need to ensure that the old connection is released, any operation is not needed, and the current process of the terminal equipment is pressed.
Step S25: if the new registration of the current operator needs to ensure that the old connection is released, when registering VoWiFi and triggering the disconnection of Wi-Fi operation, the strategy selection needs to be made when marking the Wi-Fi connection next time, and the strategy selection is written into Database for inquiry when the Wi-Fi connection is made.
Example 3:
the method and the device mainly aim at a scene that both VoLTE and VoWiFi switches of the terminal equipment are turned on, and realize the process of optimizing IMS registration logic under the scene. Specifically, assuming that the network side device is an ePDG, a specific implementation process of the technical scheme provided in the embodiment of the present application is as follows:
step S31: the terminal device triggers an operation of disconnecting Wi-Fi in the VoWiFi registration state, and triggers an IMS De-Register SIP request message before Wi-Fi is disconnected, and successfully sends an IKE Information Delete message releasing the IPSec Tunnel, and at this time, the terminal device needs to query the IPSec connection policy of the operator (see step S23 in the second embodiment).
Step S32: and if the new registration of the current operator does not need to ensure that the old connection is released, any operation is not needed, and the current process of the terminal equipment is pressed.
Step S33: if the new registration of the current operator needs to ensure that the old connection is released, the previous IPSec Tunnel needs to be marked to be released at the moment, and the data base needs to be written in for inquiry when the Wi-Fi is connected.
Example 4:
the method and the device mainly aim at a scene that both VoLTE and VoWiFi switches of the terminal equipment are turned on, and realize the process of optimizing IMS registration logic under the scene. Specifically, assuming that the network side device is an ePDG, a specific implementation process of the technical solution provided in the embodiment of the present application is as follows:
step S41: when the terminal device successfully establishes the IPSec Tunnel by registering VoWiFi, the ePDG starts a DPD Timer, and initiates detection information to the terminal device when the DPD Timer is Expired so as to know whether the opposite terminal is in an Alive state or a Dead state. Therefore, the terminal device may mark whether the DPD Timer on the ePDG side is extended or not through subsequent operations when IPSec Tunnel connection is established or when an IKE Information message triggered by the network side during DPD Timer extended is received.
Step S41: the terminal device inquires of the IPSec connection policy of the operator (see step S23 in embodiment two).
Step S42: and if the new registration of the current operator does not need to ensure that the old connection is released, any operation is not needed, and the current process of the terminal equipment is pressed.
Step S43: and if the new registration of the current operator needs to ensure that the old connection is released, the terminal equipment reads the DPD Timer configuration T1 of the current operator.
It should be noted that the DPD Timer information T1 of the relevant operator may be obtained from the operator or known by the terminal device through some tests, and then stored in Database or List for querying.
Step S44: when the IPSec Tunnel connection is established or an IKE Information message triggered by the network side during DPD Timer Expired is received, the terminal device starts a Timer T2 (note that the time of T2 needs to be the same as T1), and marks the DPD Timer as a non-Expired state by default.
Step S45: in the operation of the local Timer T2 of the terminal device, before T2 extended, the DPD Timer extended state read in description 2 of the first embodiment of the present invention is "no".
Step S46: and when the local Timer T2 of the terminal equipment is expanded, marking the DPD Timer as an expanded state, and writing the DPD Timer into Database for inquiry when the Wi-Fi is connected. After T2 extended, the DPD Timer extended state read in description 2 of the first embodiment of the present invention is "yes".
