Abstract

Embodiments of this application provide a wireless communication method, customer premise equipment CPE, user equipment UE, and a network side device. In the wireless communication method, a target bearer is used by the UE to perform VOWIFI service communication, and is a dedicated target bearer that is established by the network side device and that is used to transmit VOWIFI communication data. Then, the VOWIFI communication data of the UE may be transmitted by using the dedicated target bearer, to be specific, the CPE may parse and process the VOWIFI data of the UE into data that can be transmitted on the dedicated target bearer.

First claim

What is claimed is:

1. A communication device, which is customer premise equipment (CPE) or an apparatus included in the CPE, comprising:
at least one processor; and
one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising:
sending capability information of customer premise equipment (CPE) to user equipment (UE), wherein the capability information of the CPE is used by the UE for determining whether the CPE is for processing voice over wireless fidelity (VOWIFI) service communication;
receiving a call request message from the UE;
sending, based on the call request message, a bearer setup request message to a network side device, wherein the bearer setup request message indicates a request to set up a target bearer—for VOWIFI service communication;
after receiving a bearer setup response message from the network side device, sending a call response message to the UE;
receiving initial uplink VOWIFI data from the UE;
parsing the initial uplink VOWIFI data to obtain target uplink VOWIFI data; and
transmitting the target uplink VOWIFI data of the UE on the target bearer.

2. The communication device according to claim 1 , wherein the operations further comprise:
receiving a registration message from the UE; and
sending a registration response message to the UE, wherein the registration response message comprises capability information of the CPE.

3. The communication device according to claim 1 , wherein the operations further comprise:
receiving, on the target bearer, initial downlink VOWIFI data from the network side device;
parsing the initial downlink VOWIFI data to obtain target downlink VOWIFI data; and
sending the target downlink VOWIFI data to the UE.

4. The communication device according to claim 1 , wherein the operations further comprise:
receiving a target paging message from the network side device, wherein the target paging message comprises a second identifier of UE associated with the CPE;
when the UE is within a service scope of the CPE, sending a call request message to the UE;
after receiving a call response message from the UE, sending a bearer setup request message to the network side device, wherein the bearer setup request message indicates a request message to set up the target bearer, and the target bearer is for VOWIFI service communication; and
transmitting VOWIFI data of the UE on the target bearer.

5. A communication device, which is user equipment (UE) or an apparatus included in the UE, comprising:
at least one processor; and
one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising:
receiving capability information of customer premise equipment (CPE) from the CPE, wherein the capability information of the CPE comprises a network support capability of the CPE;
determining, based on the capability information of the CPE, whether the CPE is for processing voice over wireless fidelity (VOWIFI) service communication, wherein when the network support capability of the CPE comprises an internet protocol multimedia subsystem (IMS) voice access capability, the CPE is for processing the VOWIFI service communication, and when the network support capability of the CPE does not comprise the IMS voice access capability, the CPE is not for processing the VOWIFI service communication;
when the CPE is for processing the VOWIFI service communication, sending a call request message to the CPE; and
after receiving a call response message from the CPE, sending VOWIFI data to the CPE.

6. The communication device according to claim 5 , wherein the capability information of the CPE comprises an air interface channel condition of the CPE, and the operations further comprise:
determining whether the air interface channel condition of the CPE meets a threshold; and
when the air interface channel condition of the CPE meets the threshold, processing the VOWIFI service communication by using the CPE; or
when the air interface channel condition of the CPE does not meet the threshold, processing the VOWIFI service communication without using the CPE.

7. The communication device according to claim 5 , wherein the capability information of the CPE comprises an air interface channel condition of the CPE, and the operations further comprise:
determining whether the air interface channel condition of the CPE is superior to an air interface channel condition of a mobile data network; and
when the air interface channel condition of the CPE is superior to the air interface channel condition of the mobile data network, processing the VOWIFI service communication by using the CPE; or
when the air interface channel condition of the CPE is not superior to the air interface channel condition of the mobile data network, processing the VOWIFI service communication without using the CPE.

8. The communication device according to claim 5 , wherein the operations further comprise:
sending a registration message to the CPE; and
receiving a registration response message from the CPE, wherein the registration response message comprises the capability information of the CPE.

9. A communication device, which is a network side device or an apparatus included in the network side device, comprising:
at least one processor; and
one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising:
obtaining a first paging message, wherein the first paging message comprises a target paging message and a first identifier of customer premise equipment (CPE), wherein the target paging message comprises a second identifier of user equipment (UE) associated with the CPE;
sending the target paging message to the CPE corresponding to the first identifier;
receiving a bearer setup request message from the CPE, wherein the bearer setup request message indicates a request message to set up a target bearer, and the target bearer is for voice over wireless fidelity (VOWIFI) service communication;
after the target bearer is set up, sending a bearer setup response message to the CPE; and
transmitting VOWIFI data of the UE on the target bearer.

10. The communication device according to claim 9 , wherein the operations further comprise:
obtaining a second paging message, wherein the second paging message comprises the second identifier; and
determining the first identifier based on the second identifier.

11. The communication device according to claim 9 , wherein the operations further comprise:
when the network side device fails to perform paging by using the second identifier, triggering execution of sending the target paging message to the CPE based on the first identifier.
