Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.
For a dual-card dual-standby VoLTE terminal, the concurrence of the data service and the VoLTE service can be realized on the same card, but when one card performs the data service, if the other card establishes VoLTE connection, the card performing the data service is forced to be interrupted. For data services with high real-time performance, such as online games and video services, forced interruption of the data services inevitably brings poor use experience to users.
The invention provides a data service switching method and a device, aiming at a dual-card dual-standby VoLTE terminal, network side equipment can monitor service use conditions of two cards in real time, when a VoLTE service request calling a second SIM card is received and a data service of a first SIM card is detected at the moment, the terminal is indicated to switch the data service to the second SIM card, and after the switching is completed, the terminal is informed to establish the VoLTE service of the second SIM card, so that the data service and the VoLTE service are simultaneously carried out on the second SIM, a user can use the data service while connecting the VoLTE connection, and the user experience degree is greatly improved.
The following describes the technical solutions of the present invention and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 1 is a system framework diagram related to a data service switching method provided by the present invention, and the system framework diagram shown in fig. 1 includes: terminal and network side equipment.
The terminal can be any mobile device capable of supporting dual-card dual standby and using data service and VoLTE voice service by two cards.
The network side device may be a device for accessing the terminal to the wireless network. The device may be a base station or various wireless access points or may refer to a device in an access network that communicates over the air-interface, through one or more sectors, with the terminals. For example, the base station may be an evolved Node B (eNB) or eNodeB in Long Term Evolution (LTE).
Fig. 2 is a signaling flowchart of a first implementation of the data service switching method provided in the present invention, and as shown in fig. 2, the data service switching method provided in this embodiment includes:
s201, when network side equipment receives a VoLTE service request for calling a second subscriber identity SIM card and detects that a first subscriber identity SIM card is carrying out data service, data transmission with the first SIM card is interrupted.
For a dual-card dual-standby VoLTE terminal, if one card performs a data service and the other card establishes a VoLTE call connection, the establishment of a high-quality IP channel used by the VoLTE call connection may cause the card performing the data service to enter an offline state. In order to solve the technical problem, in the data service switching method provided in this embodiment, the network side device may monitor service usage on two cards of the terminal in real time, and immediately interrupt data transmission with the first SIM card when receiving a VoLTE service request for calling the second SIM card and monitoring that the first SIM card is performing a data service. And the first SIM card and the second SIM card are both installed on the terminal. Namely, the first SIM card and the second SIM card realize communication with the network side equipment through one terminal.
In order to enable the network side device to know that the first SIM card and the second SIM card belong to the same terminal, before S201, the terminal may send, to the network side device, the first IMSI of the first SIM card, the first IMEI corresponding to the first SIM card, the second IMSI of the second SIM card, the second IMEI corresponding to the second SIM card, and the association information of the first SIM card and the second SIM card. After receiving the association information, the network side device may determine that the first SIM card and the second SIM card belong to the same terminal according to the association information.
S202, the network side equipment sends a switching instruction to the terminal.
And S203, the terminal switches the data service performed on the first SIM card to the second SIM card according to the switching instruction.
And after receiving the switching instruction, the terminal stops the data service performed on the first SIM card and switches the data service from the first SIM card to the second SIM card.
In order to enable the terminal to establish a VoLTE call connection on the second SIM, the method provided in this embodiment further includes, after S203:
s204, the network side equipment sends a request for establishing the VoLTE service on the second SIM card to the terminal;
s205, the terminal establishes the VoLTE service on the second SIM card according to the request.
After receiving a request sent by the network side device for establishing the VoLTE service on the second SIM card, the terminal establishes the VoLTE service on the second SIM card.
Because the terminal switches the data service performed on the first SIM card to the second SIM card, and then performs the VoLTE service established on the second SIM card, the data service and the VoLTE service are performed on the second SIM card at the same time, but not on two cards, respectively, and in this case, the data service does not enter the offline state due to the establishment of the VoLTE voice service. Therefore, the user can use the VoLTE call service and the data service simultaneously, and the user experience degree is greatly improved.
In the data service switching method provided in this embodiment, when receiving a VoLTE service request for calling a second SIM card and detecting that a first SIM card is performing a data service, a network side device interrupts data transmission with the first SIM card and sends a switching instruction to a terminal, so that the terminal switches the data service performed on the first SIM card to the second SIM card according to the switching instruction. The user can use the VoLTE voice service and the data service at the same time, and the user experience degree is greatly improved.
Fig. 3 is a signaling flowchart of a second embodiment of the data service switching method provided in the present invention, and on the basis of the foregoing embodiment, the data service switching method provided in this embodiment further includes, before S201:
s301, sending the first IP address of the first SIM card and the second IP address of the second SIM card to the network side equipment.
The first SIM card adopts a first IP address and network side equipment to transmit data services, and the second SIM card adopts a second IP address and network side equipment to transmit data services.
Alternatively, one way to implement S203 may be:
s2031, the terminal establishes the data exclusive bearer of the second SIM card.
And the data of the second SIM card exclusively bears the data used for transmitting the interaction between the second SIM card and the network side equipment.
S2032, the terminal sends a data recovery request to the network side equipment.
S2033, the network side equipment sends first data to be sent to the first SIM card originally to the second SIM card according to the first IP address and the second IP address.
The terminal stops data service performed on the first SIM card after receiving the switching instruction, and establishes a data exclusive bearer of the second SIM card, and in order to switch the data service originally performed on the first SIM card to the second SIM card, the terminal can send a data recovery request to the network side equipment, and after receiving the data recovery request, the network side equipment sends first data originally to be sent to the first SIM card to the second SIM card according to the IP addresses of the two SIM cards. Thus, data traffic on the first SIM card is switched to the second SIM card.
The data service switching method provided in this embodiment provides an implementable manner for switching a data service performed on the first SIM card to the second SIM card, and in this manner, it can be ensured that the data service is switched to the second SIM card before the second SIM card establishes the VoLTE voice service, so that the user can use the VoLTE voice service and the data service at the same time, and the user experience is improved.
For a user, a flow package handled by two cards on a dual-card dual-standby mobile phone may be different, and the user may want to preferentially use the card with a larger flow to process a data service. Fig. 4 is a signaling flowchart of a third embodiment of the data service switching method provided by the present invention, and assuming that a user wants to preferentially use a first SIM card for data service, as shown in fig. 4, before S201, the data service switching method provided by this embodiment further includes:
s401, sending a data service preference to the network side equipment, wherein the data service preference is used for indicating that the use priority of the data service of the first SIM card is higher than that of the data service of the second SIM card.
Optionally, the data preference in S401, the first IP address and the second IP address in S301, and the first IMSI, the first IMEI, the second IMSI, the second IMEI, and the association information in the foregoing embodiment may be simultaneously sent to the network side device.
S402, the network side equipment judges whether the terminal finishes the VoLTE service.
And S403, if yes, sending second data to be sent to a second SIM card originally to the first SIM card according to the first IP address and the second IP address based on the data service preference.
Optionally, after the terminal finishes the VoLTE service, the terminal may directly send a notification message to the network side device to notify that the VoLTE service established on the second SIM card of the network side device is finished. After receiving the message, the network side device may send the second data originally to be sent to the second SIM card to the first SIM card with a higher priority according to the data service preference sent by the terminal in advance.
Optionally, the terminal may establish a data dedicated bearer of the first SIM card while sending the notification message to the network side device, so as to transmit the second data.
In the data service switching method provided by this embodiment, the data service preference is sent to the network side device, so that the network side device sends the data service to the SIM card with a higher priority after the VoLTE service is ended at the terminal, and the data transmission channel can be flexibly switched according to the priority of the SIM card data service, thereby further improving the user experience.
