The following specifically describes a voice call method and a voice call apparatus according to exemplary embodiments of the present disclosure.

The present exemplary embodiment first discloses a voice call method, and fig. 3 shows a flow of the voice call method in the present exemplary embodiment, including the following steps S310 to S340:

step S310, when it is detected that the ue enters a new tracking area, sending a tracking area update request to the network side, where the bearer information in the tracking area update request is null.

The present exemplary embodiment is applied to a user equipment, wherein the user equipment is in a standby state. The user equipment is an electronic device capable of performing a voice call, such as a smart phone. The user equipment in the standby state may include:

the user equipment initiates or receives voice service, and the user equipment and the network side do not establish voice bearing.

The voice service specifically refers to a service in which a user makes a voice call, such as making a call or receiving a call. The Voice service may include Voice over Long-Term Evolution (VoLTE) service, that is, in the exemplary embodiment, the Voice service established between the device and the network side is based on the IMS.

Generally, if the user equipment establishes a voice bearer with the network side while performing a voice service, the exemplary embodiment is applied when the user equipment initiates or receives a voice service and the user equipment and the network side do not establish a voice bearer. The voice service can be initiated or received when the device used by the user is in a dial-up outgoing state, or when there is an incoming call from other user devices, and the like.

TA (Tracking Area) is a new concept set by network systems such as LTE and the like for location management of a ue, and the function of TA is to manage the location of the ue, and may be defined as one or more continuous cells, each TA has its own unique TAI (Tracking Area Identity), and TAs cannot overlap with each other. The method comprises the following steps that a plurality of TAs can form a tracking area list, a core network allocates the tracking area list to user equipment, and when the user equipment is in an idle state, the core network can know the TA where the user equipment is located and further can know the position where the user equipment is located; when the user equipment in the idle state needs to be paged, paging is performed in all cells of the tracking area assigned by the user equipment.

In an exemplary embodiment, the detecting that the user equipment enters the new tracking area may include:

and detecting that the user equipment enters a new tracking area, and failing to search the new tracking area in the current tracking area identification list.

That is, when the ue enters a new TA that is not in the Tracking area list allocated to the ue, it is found that the TAC (Tracking area code) of the new TA is not in the Tracking area list allocated to the ue, and thus, it is necessary to perform a TAU (Tracking area Update). At this time, the user equipment sends a tracking area update request to the network side.

The functions implemented by the TAU procedure may include: when the user equipment carries out a new TA, updating the current position of the user equipment to a network side; periodically updating, and periodically reporting the current position by the user equipment; the user equipment capability is changed and updated to the network side; when the EPS network load changes, the network side is informed to determine which load is still in the activated state.

In general, the area tracking update request may generally include various information, such as a GUTI (Globally Unique Temporary UE identity) of the UE, a network operating capability of the UE, an EPS update type, an EPS bearer context status, and the like. When the ue performs TAU, the tracking area update request sent to the network side may include bearer information, for example, an evolved packet system bearer context state, where "0" may indicate that the voice/data activation bearer fails, and "1" indicates that the voice/data activation bearer succeeds. However, this method often causes data asynchronism between the ue and the network side for carrying information, which results in an abnormal voice call between the ue and the network side.

Therefore, in the present exemplary embodiment, the area tracking update request may be specially processed, so that the bearer information therein is empty. Specifically, in an exemplary embodiment, before sending the tracking area update request to the network side, the voice call method may further include the following steps:

information elements related to evolved packet system bearers are removed from the area update request.

I.e. such that the area update request does not contain information elements related to evolved packet system bearers.

The information element related to the dedicated bearer may include:

and the evolved packet system carries the identifier and the context state.

Generally, a user equipment may be connected to multiple PDNs (Public Data networks, PDNs), and the PDN connection may have multiple EPS bearers. The network side and the ue need an identifier to distinguish the EPS bearer, where the identifier is an EBI (evolved packet system bearer identifier). The EBI may be allocated by the MME, and is used to distinguish multiple EPS bearers of the same user equipment, and EBIs of different user equipments may be repeated. An EPS bearer context status may be used to reflect the status of the voice/data active bearer between the ue and the network side.

Step S320, receiving a voice bearer activation request sent by the network side.

When the ue does not need to perform TAU, the procedure of initiating the voice service may include: user equipment initiates a voice request to a network side; the network side receives a request for activating the voice bearer sent to the user equipment; the user equipment responds to the request for activating the voice bearer; a voice bearer is established. And the process of receiving the voice service may include: a network side sends a voice request; and sending a request for activating the voice bearer to the user equipment; the user equipment responds to the request of the voice bearer; a voice bearer is established. That is, when the user equipment establishes the voice bearer, it needs to receive a voice bearer activation request sent by the network side.

In an exemplary embodiment, the network side may include an MME (Mobility Management Entity). The MME refers to a key control node of a 3GPP protocol LTE system access network, is responsible for positioning and paging processes of idle mode user equipment, and may relate to an activation or deactivation process of a voice bearer. The functions may specifically include: sending a paging message; safety control; mobility management in idle state; SAE bearer management; encryption and integrity protection of NAS (Network access Server) signaling, and the like.

Step S330, receiving the voice bearer activation request to establish a voice bearer between the ue and the network side, where the voice bearer is used to transmit voice data.

In practical applications, when the ue needs to perform TAU, the voice service process may include: user equipment initiates a voice request to a network side; user equipment initiates a TAU request; the network side sends a request for activating the voice bearing to the user equipment; the user equipment ignores the voice bearing activating request; voice bearer establishment fails; the network side sends a TAU receiving request to the user terminal.

That is, when the ue needs to perform TAU, the voice bearer setup is often failed, so that normal voice call cannot be performed.

Step S340, receiving a tracking area update acceptance message fed back by the network side in response to the tracking area update request, and updating the tracking area to a new tracking area.

In this exemplary embodiment, after receiving a tracking area update request sent by a user equipment, a network side may return feedback information about receiving of a tracking area update to the user equipment, so that the user equipment updates from a current tracking area to a new tracking area, thereby completing a process of TAU. If the tracking area update acceptance message includes the new GUTI allocated to the user equipment, the user equipment further needs to reply a tracking area update completion message to the network side, otherwise, the reply may not be needed.

Based on the above description, in the present exemplary embodiment, when performing a TAU, the ue in a standby state receives a voice bearer activation request, and does not carry bearer information in a tracking area update request, so that the ue establishes a normal voice bearer with a network side while completing the TAU, thereby improving a success rate of the call.

To sum up, in the present exemplary embodiment, the present exemplary embodiment is applied to a user equipment, where the user equipment is in a state to be communicated, and when it is detected that the user equipment enters a new tracking area, a tracking area update request is sent to a network side, and bearer information in the tracking area update request is null; receiving a voice bearing activation request sent by a network side; receiving a voice bearer activation request to establish a voice bearer between the user equipment and the network side, wherein the voice bearer is used for transmitting voice data; and receiving a tracking area update acceptance message fed back by the network side in response to the tracking area update request, and updating the tracking area to a new tracking area. On one hand, the present exemplary embodiment provides a new voice call method, which enables a user equipment to receive a voice bearer activation request sent by a network side when the user equipment sends a tracking area update request to the network side, so that the user equipment can establish a normal voice bearer with the network side while completing the tracking area update, thereby improving the success rate of voice call; on the other hand, in the exemplary embodiment, the bearer information is set to be null in the tracking area update request, so that the problem of asynchronous bearer information between the user terminal and the network side is avoided, and the efficiency and accuracy of establishing the voice call are improved.
