Description

Bearer establishment method, device, medium and terminal equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a bearer establishment method, apparatus, medium, and terminal device.

Background

At present, a Voice over wifi (Voice over wifi) registration process based on a wireless access technology needs to establish a bearer first, and a registration message is initiated to interact with an operator network after the bearer is established. When a bearer is established, an Evolved Packet Data Gateway (EPDG) address list of a matched operator needs to be obtained first, and the addresses in the list are used in sequence to attempt to establish the bearer. At present, no matter the terminal device is disconnected after wireless-fidelity (Wifi) is disconnected and then connected or the terminal is restarted, the terminal device tries to establish a bearer from the first address in the first list every time, if the attempt to establish the bearer fails, the next address is tried to establish the bearer again, and in the process, the query time may be too long, or the attempt connection time is too long, so that the registration time of the VoWifi is seriously influenced.

Therefore, a method for improving the registration efficiency of the VoWifi is urgently needed so that the terminal can re-register the VoWifi as soon as possible after the terminal is restarted or the network is abnormally disconnected.

Disclosure of Invention

The embodiment of the invention provides a bearer establishment method, a bearer establishment device, a bearer establishment medium and terminal equipment, which are used for improving VoWifi registration efficiency.

In a first aspect, an embodiment of the present invention provides a bearer establishment method, where the method includes: in a VoWifi registration process, acquiring an EPDG address set of an operator currently supported by the terminal equipment; initiating the establishment of the bearer by sequentially using the addresses in the EPDG address set; when the bearing is successfully established by using the Kth address in the EPDG address set, saving the Kth address into a white list; and in the next VoWifi registration process, initiating the establishment of the bearer by utilizing the Kth address in the white list.

The method provided by the invention has the beneficial effects that: because the address is stored in the white list when the EPDG address is successfully inquired by registering the VoWifi for the previous time, the address in the white list can be directly used for carrying out the establishing process when the VoWifi needs to be registered again for the next time, and invalid attempts of wrong addresses are reduced, so that the bearing establishing time can be shortened, and the VoWifi registering efficiency is improved.

In one possible implementation, the method further comprises: and when the carrier is successfully established by using the Kth address in the EPDG address list, storing K-1 addresses before the Kth address into a blacklist. Therefore, under the condition that other addresses except the blacklist exist, the other addresses are preferentially used, the invalid attempt times of the error address are reduced, the bearing establishing duration is favorably shortened, and the VoWifi registration efficiency is improved.

In one possible implementation, the method further includes: after the Kth address in the white list is used for initiating the bearing establishment failure, determining a candidate address set in the EPDG address list except the Kth address and the address in the black list; and initiating the establishment of the load bearing by using the addresses in the candidate address set in sequence. In this way, even if the address successfully registered before can not be registered again due to network reasons, the address in the candidate address set can be used for initiating the establishment of the bearer adaptively.

In one possible implementation, the method further includes: when the bearing is not established by using the address in the candidate address set, the bearing is established by using the address in the EPDG address set again; and when the addresses in the EPDG address set are used again to initiate and establish the load bearing and the load bearing fails, determining that the VoWifi registration fails.

In a possible implementation scheme, in the VoWifi registration process, both the SIM card of the subscriber identity module of the terminal device and the usage area scenario are maintained unchanged. The embodiment is applied to registering VoWifi again in the above scene to reduce the time length for acquiring the EPDG address list and the time length for trying to establish a bearer by each address in the polling list, and can effectively improve the network residence speed.

In a second aspect, an embodiment of the present invention further provides a bearer establishment apparatus, where the bearer establishment apparatus executes a module/unit of any one of the possible design methods in the first aspect. These modules/units may be implemented by hardware, or by hardware executing corresponding software.

In a third aspect, an embodiment of the present invention provides a terminal device, which includes a processor and a memory. Wherein the memory is used to store one or more computer programs; the one or more computer programs stored in the memory, when executed by the processor, enable the terminal device to implement the method of any one of the possible designs of the first aspect described above.

In a fourth aspect, an embodiment of the present invention further provides a computer-readable storage medium, where the computer-readable storage medium includes a computer program, and when the computer program runs on a terminal device, the computer program causes the terminal device to perform any one of the possible design methods of the first aspect.

In a fifth aspect, an embodiment of the present invention further provides a computer program product, which, when running on a terminal, causes the terminal device to execute any one of the possible designs of the first aspect.

As for the advantageous effects of the above second to fifth aspects, reference may be made to the description in the above first aspect.

As shown in fig. 2, a method for establishing a bearer according to an embodiment of the present application is shown, where the method includes:

s201, in a VoWifi registration process, acquiring an EPDG address set of an operator currently supported by the terminal device.

In this step, both the SIM card of the subscriber identity module of the terminal device and the usage area scenario remain unchanged. For some operators, or because the server itself is unstable, or because of uncertain factors such as region, generally, a string of EPDG addresses that the terminal device can query, some of the EPDG addresses can be used in this time period, and the next EPDG addresses cannot be used in the next time period; some of them cannot be used until the last address; some time is overtime and has no response, and various error codes are returned at one time. Therefore, before the terminal device performs the VoWifi registration process, it needs to acquire an EPDG address of an operator currently supported by the terminal, and generate an EPDG address set including a plurality of EPDG addresses. For example, if the operator currently supported by the terminal is a mobile operator, the EPDG address of the current mobile operator of the terminal is acquired.

S202, the addresses in the EPDG address set are used for initiating the establishment of the bearer in sequence.

S203, when the bearing is successfully established by using the Kth address in the EPDG address set, the Kth address is saved in a white list.

Optionally, the method further includes: and when the carrier is successfully established by using the Kth address in the EPDG address list, storing K-1 addresses before the Kth address into a blacklist.

And S204, in the next VoWifi registration process, utilizing the Kth address in the white list to initiate the establishment of the bearer.

Referring to fig. 3, in the first registration process of the VoWifi, the terminal device first sends a request message for querying an EPDG address to the network device S301. S302, the network device returns an EPDG address set to the terminal device, wherein the EPDG address set comprises M addresses, and M is a positive integer. S303, the terminal device tries to send a bearer establishment request to the network device from the first address in the EPDG address set in sequence. S304, the network device returns the bearing establishment result to the terminal device. S305, if the address is successful, the terminal equipment stores the address to a white list and continues the subsequent process; s306, if the address fails, the terminal device stores the address to a blacklist, and tries to send a bearer establishment request to the network device by using the next address in the EPDG address set until the bearer establishment request is sent to the network device by using the Kth address in the EPDG address set, so that the bearer establishment is successful. After S307, this embodiment further includes the steps of: s308, acquiring the Kth address in the white list in the next VoWifi registration process. S309, the terminal device uses the Kth address to send a load building request to the network device. S309, the network device returns the result of establishing the load to the terminal device. And S310, if the address is successful, the terminal equipment stores the address to a white list and continues the subsequent process. S311, if the address fails, the terminal equipment stores the K address to a blacklist. The terminal equipment determines a candidate address set in the EPDG address list except the Kth address and the address in the blacklist; and initiating the establishment of the load bearing by using the addresses in the candidate address set in sequence.

It should be noted that, during the subsequent VoWifi registration process, the terminal device may still preferentially use the address in the white list, and when the address in the white list is unavailable, try to establish a bearer by using the address other than the white list and the black list.

Optionally, when initiating bearer establishment by using the addresses in the candidate address set fails, initiating bearer establishment by using the addresses in the EPDG address set again; and when the addresses in the EPDG address set are used again to initiate and establish the load bearing and the load bearing fails, determining that the VoWifi registration fails.
