The registration method of the IMS network according to the embodiment of the present application will be described in detail below with reference to fig. 2 to 5.
Referring to fig. 2, a flowchart of a registration method of an IMS network is provided in an embodiment of the present application. The present embodiment is exemplified by applying a registration method of an IMS network to a terminal device. The registration method of the IMS network can comprise the following steps:
s201, when the first registration of the VoWiFi network fails, the terminal equipment retransmits the first registration request to the VoWiFi network through the WiFi network within preset retry duration at preset time intervals.
The first registration of the VoWiFi network comprises registration initiated after the terminal equipment is started or restarted, the terminal equipment searches for the WiFi network after the terminal equipment is started or restarted, wiFi connection is established between the terminal equipment and the WiFi network, and the terminal equipment detects that the WiFi network can be connected to the Internet. The VoWiFi network is a network used by the IMS network for carrying WiFi voice services, and comprises a plurality of network elements. The terminal device sends a first registration request to the VoWiFi network, where the first registration request may be a Session Initiation Protocol (SIP) registration request, the first registration request may carry a user identifier, an IP address, a service type identifier, and the like of the terminal device, and the first registration request is used to register to the VoWiFi network. The terminal device prestores or preconfigures retry duration and a time interval, where the retry duration is a time interval, and a starting time of the retry duration may be a time when the terminal device detects that the first registration to the VoWiFi network fails, for example: and the terminal equipment receives the registration failure response sent by the VoWiFi network. The time interval represents the time difference between two consecutive first registration requests within the retry duration. For example: the retry duration is 5s, the time interval is 1s, the terminal device sends the first registration request to the VoWiFi network at a time interval of 1s within the retry duration, and when the terminal device sends a plurality of first registration requests within the retry duration, the terminal device may number the plurality of first registration requests respectively to distinguish different first registration requests, or each first registration request carries a timestamp, which is used to distinguish the first registration requests sent at different times.
S202, when the VoWiFi network is failed to be registered within the retry duration, a second registration request is sent to the VoLTE network through the LTE network.
The VoLTE network is used for bearing LTE voice service in the IMS network, the terminal equipment sends a first registration request to the VoWiFi network according to a preset time interval within preset time duration, and when the terminal equipment detects successful registration to the VoWiFi network within retry time duration, the terminal equipment stops sending the first registration request; and if the terminal equipment does not successfully register the VoWiFi network when the end time of the retry duration is reached, the terminal equipment sends a second registration request to the VoLTE network through the LTE network.
For example: the preset time is 5s, the starting time of the preset time is t0, the ending time of the preset time is t0+5s, and the preset time interval is 1s. And the terminal equipment sends a first registration request to the VoWiFi network at the moment t0, and the terminal equipment does not receive a registration success response returned by the VoWiFi network according to the first registration request. The terminal device sends a first registration request to the VoWiFi network at the time of t0+1s, receives a registration success response returned by the VoWIFi network according to the first registration request, and does not send the first registration request to the VoWiFi network at the subsequent time of t0+2s, t0+3s, t0+4s and t0+5 s. And when the terminal equipment is successfully registered to the VoWiFi network, establishing PDN connection for bearing voice call service.
According to the content, when the terminal equipment fails to register the VoWiFi network for the first time, the terminal resends the registration of the VoWiFi network according to the preset time interval within the preset retry duration, and the terminal is switched to the LTE network for registering the VoLTE network when the terminal equipment is not successfully registered to the VoWiFi network within the retry duration, so that the problem that the registration success rate of the VoWiFi network is not high when the terminal equipment is switched to the VoLTE network immediately after the VoWiFi network is failed to register in the related technology is solved.
Referring to fig. 3, another flow chart of a registration method of an IMS network is provided for the embodiment of the present application, where the method includes the following steps:
s301, monitoring the load parameter value of the P-CSCF network element corresponding to each P-CSCF address in the P-CSCF set.
The P-CSCF (Proxy Call Session Control function) network element is the first contact node of the terminal device in the IMS network on the Control plane, the P-CSCF network element is an outbound/inbound SIP Proxy server, and SIP (Session Initiation Protocol) signaling of the terminal device must pass through the P-CSCF. The terminal device may use a local call session control function discovery mechanism to obtain the P-CSCF address.
The terminal device pre-stores or pre-configures a P-CSCF address set, where the P-CSCF address set includes a plurality of P-CSCF addresses, and the P-CSCF address set may be configured by an HSS (Home Subscriber Server) in an IMS core network. The terminal equipment has a connection relation with a plurality of P-CSCF network elements simultaneously, and P-CSCF addresses of a plurality of P-CSCF and P-CSCF addresses in a P-CSCF set. In P-CSCF collection for terminal equipment monitoring
S302, determining the target P-CSCF network element with the lightest load according to the load parameter value.
The load parameter value represents the load degree of the P-CSCF network element, and the load parameter value can use the CPU utilization rate, the memory utilization rate, the transmission delay and the like. The larger the CPU utilization rate is, the heavier the load degree of the P-CSCF network element is; conversely, the smaller the CPU utilization rate, the lighter the load degree of the P-CSCF network element. The larger the memory usage rate is, the heavier the load degree of the P-CSCF is; and on the contrary, the smaller the memory usage rate is, the lighter the load degree of the P-CSCF network element is. The smaller the transmission delay is, the lighter the load degree of the P-CSCF network element is; and conversely, the larger the transmission delay is, the heavier the load degree of the P-CSCF network element is.
For example, the set of P-CSCF addresses includes: P-CSCF address 1, P-CSCF address 2, and P-CSCF address 3,P-CSCF address 1 indicates P-CSCF network element 1,P-CSCF address 2 indicates P-CSCF network element 2,P-CSCF address 3 indicates P-CSCF network element 3. The transmission delay of the terminal equipment for monitoring the P-CSCF network element 1 is 1ms, the transmission delay of the terminal equipment for monitoring the P-CSCF network element 2 is 2ms, and the transmission delay of the terminal equipment for monitoring the P-CSCF network element 3 is 1.5ms. And the terminal equipment determines that the load degree of the P-CSCF network element 1 in the 3P-CSCF network elements is the lightest, and takes the P-CSCF network element 1 as a target P-CSCF network element.
In a possible implementation manner, the terminal device obtains the priority of each P-CSCF address set in the P-CSCF address set, where the priority may be represented by using a numerical value, and when the terminal device needs to initiate an initial registration request, selects a P-CSCF address with the highest priority from the P-CSCF set as a target P-CSCF address.
S303, taking the P-CSCF address of the target P-CSCF network element as the target P-CSCF address.
According to the example in S302, the terminal device takes the P-CSCF address 1 as the target P-CSCF address.
S304, sending an initial registration request to a target P-CSCF network element.
The terminal device sends an initial registration request to a target P-CSCF network element indicated by a target P-CSCF address, where the initial registration request is a first registration request sent by the terminal device to the target P-CSCF network element for the first time, and the initial registration request is, for example: the initial registration request is a first registration request sent by the terminal to the target P-CSCF network element after being powered on or restarted, and the first registration request may be a SIP registration request based on a SIP protocol, and the initial registration request is sent by the terminal device through the WiFi network. After the terminal equipment is started or restarted, a WiFi network is searched, wiFi connection is established with the WiFi network, and when the fact that the WiFi connection can be connected to the Internet is detected, the terminal equipment sends an initial registration request to a target P-CSCF network element.
S305, a registration success response corresponding to the initial registration request is not received within a preset time length.
The terminal device prestores or preconfigures a preset time length, and the size of the preset time length can be determined according to actual needs, which is not limited in the embodiments of the present application. The method comprises the steps that terminal equipment sends an initial registration request to a VoWiFi network through a target P-CSCF network element, and when the VoWiFi network receives the initial registration request and the network between the terminal equipment and the VoWiFi network is normal, the VoWiFi network returns a registration success response to the terminal equipment; when the network between the terminal equipment and the VoWiFi network is abnormal, the terminal equipment cannot receive the registration success response returned by the VoWiFi network. For example: the preset time is 3ms, the terminal equipment starts timing at the moment of sending the initial registration request, and when a registration success response sent by the VoWiFi network is not received within 3ms, the terminal equipment is determined to be unsuccessfully registered to the VoWiFi network; or when the terminal equipment receives a registration failure response sent by the VoWiFi network within 3ms, the terminal equipment is determined not to be successfully registered to the VoWiFi network.
S306, determining that the registration to the VoWiFi network is not successful.
When the terminal equipment does not receive a registration success response from the VoWiFi network within a preset time length, determining that the VoWiFi network is not registered for the first time; or when the terminal equipment receives a registration failure response from the VoWiFi network within a preset time length, determining that the VoWiFi network is failed to be registered for the first time.
In one possible implementation manner, when the terminal device determines that the first registration of the VoWiFi network fails, the terminal device deletes the target P-CSCF address from the P-CSCF address set.
For example: according to the example of S302, the terminal device deletes the P-CSCF address 1 from the set of P-CSCF addresses.
And S307, sending a first registration request to the VoWiFi network at a preset time interval within a preset retransmission duration through the WiFi network.
The terminal device prestores or preconfigured with a retry duration and a time interval, where the retry duration is a time interval, and a start time of the retry duration may be a time when the terminal device detects that the first registration to the VoWiFi network fails, for example: and the terminal equipment receives the registration failure response sent by the VoWiFi network. The time interval represents the time difference between adjacent pairs of first registration requests within the retry duration. For example: the retry duration is 5s, the time interval is 1s, the terminal device sends the first registration request to the VoWiFi network at the time interval of 1s within the retry duration, and when the terminal device sends a plurality of first registration requests within the retry duration, the terminal device may number the plurality of first registration requests respectively to distinguish different first registration requests, or each first registration request carries a timestamp, and is used to distinguish the first registration requests sent at different times.
S308, judging whether the registration to the VoWiFi network is successful.
The terminal device judges whether the terminal device is successfully registered to the VoWiFi network within the retransmission time length, if so, S309 is executed; if not, go to step S310.
The method comprises the steps that the terminal equipment sends a first registration request to the VoWiFi network according to a preset time interval within preset time length, and when the terminal equipment detects successful registration to the VoWiFi network within retry time length, the terminal equipment stops sending the first registration request; and if the terminal equipment does not successfully register the VoWiFi network when the end time of the retry duration is reached, the terminal equipment sends a second registration request to the VoLTE network through the LTE network.
For example: the preset time is 5s, the starting time of the preset time is t0, the ending time of the preset time is t0+5s, and the preset time interval is 1s. The terminal equipment sends a first registration request to the VoWiFi network at the moment of t0, and the terminal equipment does not receive a registration success response returned by the VoWiFi network according to the first registration request. The terminal device sends a first registration request to the VoWiFi network at the time of t0+1s, receives a registration success response returned by the VoWIFi network according to the first registration request, and does not send the first registration request to the VoWiFi network at the subsequent time of t0+2s, t0+3s, t0+4s and t0+5 s. And when the terminal equipment is successfully registered to the VoWiFi network, establishing PDN connection for bearing voice call service.
And S309, establishing PDN connection.
And S310, sending a second registration request to the VoLTE network through the LTE network.
According to the content, when the terminal equipment fails to register the VoWiFi network for the first time, the terminal resends the registration of the VoWiFi network according to the preset time interval within the preset retry duration, and the terminal is switched to the LTE network for registering the VoLTE network when the terminal equipment is not successfully registered to the VoWiFi network within the retry duration, so that the problem that the registration success rate of the VoWiFi network is not high when the terminal equipment is switched to the VoLTE network immediately after the VoWiFi network is failed to register in the related technology is solved.
