Description

Terminal device communication control method and terminal device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a terminal device communication control method and a terminal device.

Background

Since LTE (Long Term Evolution) is a network system only supporting a data domain, when an LTE handset needs to use a voice service, there are two solutions, one is a voice over LTE (voice over LTE) technology based on voice over IP (VoIP for short), and the voice over LTE is a telephone service based on ims (IP multimedia subsystem). The voice service is established in a Packet Switch Domain (PS Domain for short), has high spectrum utilization rate, clear conversation and short time delay, and will become a mainstream voice solution as the LTE network is increasingly mature. Another is to make the mobile phone Fall Back to the 2G/3G network supporting the Circuit Domain by the Circuit Switched Domain Fall Back (CSFB for short) technology. The voice of the scheme is established in a Circuit Switched Domain (CS Domain for short), and the method has rich terminal products and wide network coverage.

Srvcc (single Radio Voice continuity) is a Voice over LTE (Voice over LTE) Voice service continuity scheme proposed by 3GPP, and mainly aims to solve the problem of how to ensure Voice Call continuity when a single Radio UE moves between an LTE/Pre-LTE network and a 2G/3G CS network, that is, to ensure a smooth handover between VoIP Voice and CS domain Voice controlled by IMS by the single Radio UE across systems. bsrvcc (SRVCC before ringing) is the SRVCC handover that occurs before the ringing of the VOLTE call service. Currently, the operator network does not support bSRVCC.

Nowadays, more and more terminal devices already support the VoLTE service, and users can enjoy the high-quality 4G voice service by using the terminal devices supporting the VoLTE service. However, as the VoLTE network is not completely commercial yet, the deployment is not perfect, and the base station is not good in optimizing the VoLTE network, when a user initiates a one-pass VoLTE voice service, some network errors often occur in the process of interaction between the mobile phone and the network. For example:

1. when the return error code is 504, the handset will actively CSFB to GSM/WCDMA network and initiate a voice call in circuit domain.

2. When the return error code is 402, the handset will actively hang up the phone without attempting other actions such as redialing.

3. When the error code is returned to 580, the handset will initiate a redial in the IMS data field.

These results in a long waiting time for the voice call of the user and a very poor experience.

Detailed Description

In order to make the objects, features and effects of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings.

The terminal device, i.e. User Equipment (UE), referred to in this application may be a wireless terminal or a wired terminal, and the wireless terminal may be a device providing voice and/or data connectivity to a User, a handheld device having a wireless connection function, or another processing device connected to a wireless modem. Wireless terminals, which may be mobile terminals such as mobile telephones (or "cellular" telephones) and computers having mobile terminals, such as portable, pocket, hand-held, computer-included, or vehicle-mounted mobile devices, may communicate with one or more core networks via a Radio Access Network (RAN), which may exchange language and/or data with the RAN. Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like. A wireless Terminal may also be referred to as a system, a Subscriber unit (Subscriber unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), an Access Point (Access Point), a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Terminal (User Terminal), a User Agent (User Agent), a User Equipment (User device), or a User Equipment (User Equipment).

The first embodiment is as follows:

referring to fig. 1, a method for controlling communication of a terminal device according to an embodiment of the present invention includes:

s201: a UE camped on an LTE network successfully registers with IMS.

After the UE is started, the equipment can reside in a 2G (GSM, CDMA), 3G (WCDMA, CDMA2000, TD-SCDMA) or 4G (TD-LTE, FDD-LTE) network, and when the equipment resides in an 2/3G network, the UE can perform voice service and 2/3G data service based on a circuit domain. When the UE resides in the 4G network, the UE can realize 4G high-speed data service, and the voice service is distinguished according to whether the equipment supports VoLTE. If the 4G terminal equipment does not support VoLTE, the voice service can be realized only based on the 2/3G circuit domain; when a user enjoys the high-speed 4G data service and suddenly inserts the voice service, the 4G data service is interrupted, the network is switched from the 4G network of the packet switching domain to the 2/3G network of the circuit switching domain, and the high-speed 4G data service is recovered only when the voice service is finished; if the 4G terminal device supports VoLTE, the above problem does not exist because the voice service is encoded into the same IP data packet as the 4G data service, and is commonly carried on the LTE network. Only 4G terminals supporting VoLTE may be able to successfully register with IMS.

S202: the UE initiates an IMS-based VoLTE voice call request.

The 4G terminal supporting the VoLTE initiates a VoLTE voice call request based on the packet switching domain, and compared with the traditional circuit domain voice service, the voice service has the advantages of short connection time, clearer and more vivid voice and is more suitable for video call with large data demand.

S203: and judging that at least one of the UE and the network side equipment does not support bSRVCC.

And judging whether the UE and the network both support bSRVCC by reading the bSRVCC configuration information in the terminal and the bSRVCC information received by the network side. If either of the parties does not support bSRVCC, a timer is set and started.

S204: the timer starts timing and checks if the time has expired when the ringing message is received.

After the timer starts to count time, it starts to detect whether the ring message (IMS _ SIP _ INVITE/RINGING) responded by the network side is received. The response message is based on a reply of a VoLTE voice call request initiated by the terminal to the network side before. Due to the fact that the existing LTE network construction, VoLTE network optimization and the like are incomplete, the problems can cause that the terminal cannot receive the ringing message of the network side for a long time. In order to reduce the waiting time of the voice call of the user, when the VoLTE voice service is initiated, a timer is additionally arranged to detect whether the waiting time of the user is too long. The time required for a VoLTE voice call to succeed is currently normally 10 seconds. The predetermined time of the timer can be set to 10 seconds accordingly. The predetermined time of the timer is not constant and can be set by default or manually, but must be based on the existing network deployment.

S205: and judging whether the Timer is overtime or not, if so, considering that the Volte voice service can not be connected, executing step S206, and if not, after clearing the Timer, executing step S208.

When the ringing message sent by the network side equipment is not received within the preset time of the timer, the timer is overtime, the VoLTE voice call failure can be determined, and a new voice call request needs to be initiated again. When the timer receives the ringing message sent by the network side equipment within the preset time, the timer does not time out, which indicates that the VoLTE voice call is successful, and at this time, the timer is cleared.

S206: and triggering the UE to initiate a voice call based on the circuit domain after the timer is overtime.

After the timer is over, it indicates that the 4G voice service call based on the packet switched domain has failed, and the terminal may make another voice service mode (i.e. voice call based on the circuit switched domain).

S207: after the UE normally CSFB to the 2G/3G network, the call is successfully started on the 2G/3G network.

The terminal initiates a CSFB drop from the packet switched domain of 4G back to the circuit domain of 2/3G to make a voice call. The network in which the fallback performs the voice service is not limited to the GSM network only, but may be a CDMA or WCDMA network.

S208: the voice service call is successful.

The voice service call is successfully divided into two cases: the situation that the timer is not overtime is reached through the branch of S205, the voice service is VoLTE high-definition voice service, and the user prefers the scheme; the voice service which is reached through the S207 branch is realized through a circuit domain fallback mode, and is a secondary selection scheme of a user.

By utilizing the technical scheme of the invention, when the VoLTE voice service call is carried out, if the terminal equipment or the network side equipment is detected not to support bSRVCC, whether the terminal equipment needs to initiate a new voice call request is determined according to whether the terminal equipment can receive the ringing message sent by the network side equipment within the preset time, if the terminal equipment does not receive the ringing message of the network side within the preset time, the VoLTE voice call is determined to be failed, and the terminal equipment is triggered to carry out the voice call service in a circuit domain mode if the timer is overtime.

Example two:

referring to fig. 2, a second embodiment of the present invention provides a method for controlling communication of a terminal device, where the method includes the following steps:

s210: the terminal equipment initiates a VoLTE voice call;

s220: if at least one of the terminal equipment and the network side equipment is detected not to support bSRVCC, setting a timer; the preset time of the timer may be 10 seconds.

S230: determining whether the terminal equipment needs to initiate a new voice call request according to whether the terminal equipment can receive a ringing message sent by the network side equipment within the preset time of the timer;

s240: if the terminal equipment receives a ringing message sent by network side equipment within the preset time of the timer and indicates that the VoLTE voice call is successful, the timer is cleared;

s250: if the terminal equipment does not receive the ringing message sent by the network side equipment within the preset time of the timer, a new voice call request is initiated; the initiating of the new voice call request is based on a voice call request initiated in a CSFB mode.

When the technical scheme of the invention is used, when the VoLTE voice service call is carried out, if the terminal equipment or the network side equipment is detected not to support bSRVCC, whether the terminal equipment needs to initiate a new voice call request is determined according to whether the terminal equipment can receive the ringing message sent by the network side equipment within the preset time, if the terminal equipment does not receive the ringing message of the network side within the preset time, the VoLTE voice call is determined to be failed, and the terminal equipment is triggered to carry out the voice call service in a circuit domain mode if the timer is overtime.

Example three:

referring to fig. 3, an embodiment of the present invention provides a terminal device 100, including an information collection module 10, a decision-making judgment module 20, and a timer starting module 30, where the information collection module 10 is configured to obtain bSRVCC function information of the terminal device 100 and an LTE network; the decision-making determining module 20 is configured to determine whether a timer needs to be added according to the bSRVCC function information acquired by the information collecting module 10. The timer starting module 30 is used for starting the timer added in the decision-making module 20 according to the judgment.

And the judging and deciding module determines to start the timer when one of the terminal equipment and the network side equipment does not support bSRVCC.

And the timer starting module starts the timer to count time, and indicates that the VoLTE voice call is successful when the ringing message sent by the network side equipment is received within the preset time of the timer. And clears the timer. The timer starts to time, and when the ringing message sent by the network side equipment is not received within the preset time of the timer, the VoLTE voice call failure can be determined, and a new voice call request needs to be initiated again.

Optionally, the initiation of the new voice call request by the timer starting module in the terminal device is performed based on a CSFB circuit domain manner.

Alternatively, the predetermined time of the timer is set to 10 seconds. This data is made based on having an existing network deployment scenario. The predetermined time of the timer is not a fixed layer and can be set by default or manually.

the control module 204 is configured to determine whether the terminal device needs to initiate a new voice call request according to whether the terminal device can receive a ringing message sent by the network-side device within a predetermined time of the timer.

Specifically, the control module 204 is further configured to, when the terminal device receives a ringing message sent by a network-side device within a predetermined time of a timer, determine that the VoLTE voice call has succeeded, and clear the timer.

The control module 204 is further configured to determine that the VoLTE voice call fails when the terminal device does not receive a ringing message sent by the network-side device within a predetermined time of the timer, and control the voice call initiating module to re-initiate a new voice call request; the new voice call request is initiated based on the CSFB circuit domain mode.
