Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
The invention provides a method for determining the updating period of a tracking area, aiming at the problem of higher power consumption of user equipment caused by TAU flow in the existing data transmission.
As shown in fig. 1, a method for determining a tracking area update period according to an embodiment of the present invention includes:
step 101, sending a first tracking area update TAU period to a network side device, wherein the first TAU period is greater than a data sending period of a user device;
step 102, receiving a second TAU period sent by the network side equipment;
step 103, if the first TAU period is different from the second TAU period, requesting the network side device to issue a target TAU period of the user equipment, where the target TAU period is greater than the data sending period.
Through the above steps 101 to 103, the ue to which the tracking area update period determination method of the embodiment of the present invention is applied first sends, as in step 101, a first TAU period greater than a data sending period of the ue to the network side device, so as to notify the network side device of the TAU period currently applicable to the ue. After receiving the first TAU period, the network side device informs the user equipment of the set second TAU period, so that, in step 102, the user equipment receives the second TAU period sent by the network side device. Then, in step 103, when the first TAU period is different from the second TAU period, that is, the set TAU period in the network side device is not applicable to the ue, the ue requests the network side device to issue a target TAU period of the ue. Therefore, the UE can request a new TAU period from the network side equipment when knowing that the TAU period set by the network side equipment is not applicable, so as to avoid an extra TAU flow when the TAU period set by the network side equipment is smaller than the data transmission period, thereby reducing the power consumption of the UE.
Specifically, step 101 includes:
generating a first TAU period according to a data sending period of user equipment;
sending a TAU message or a startup attachment message to network side equipment; wherein the TAU message or the power-on attach message carries the first TAU period.
Here, first, a first TAU period greater than the data transmission period is generated according to the data transmission period of the user equipment, and then the first TAU period is carried by the TAU message or the power-on attach message, and the first TAU period is transmitted to the network side equipment. Therefore, the method of sending the first TAU cycle is completed through the existing TAU message or the startup attachment message, thereby avoiding adding a new flow and improving the resource utilization rate.
Correspondingly, the network side device carries the second TAU period to the user equipment through the TAU response message or the power-on attachment response message.
It should be noted that, when the first TAU period is different from the second TAU period, and the ue requests the network side device to issue the target TAU period of the ue, although the ue can directly perform a new TAU period request by a transmission procedure with the network side device, in view of implementation in practical application, it is preferable that, as shown in fig. 2, step 103 includes:
step 1031, sending a TAU period negotiation request to the capability opening system;
step 1032, receiving a third TAU period generated by the network side device according to the TAU period negotiation request forwarded by the capability openness system, where the third TAU period is greater than the data sending period;
step 1033, determining the third TAU period as a target TAU period of the user equipment.
Here, the ue requests a new TAU cycle from the network side device through forwarding of the capability openness system, which not only ensures successful delivery of the request, but also avoids the impact on the transmission flow occupation between the ue and the network side device. And then, the network side equipment issues the generated third TAU period which is larger than the data sending period to the user equipment. Specifically, to ensure that the third TAU period generated by the network side device is applicable to the user device, the TAU period negotiation request includes the device identifier of the user device and the first TAU period.
Thus, after receiving the TAU period negotiation request forwarded by the capability openness system, the network side device can generate a third TAU period larger than the data transmission period based on the TAU period generation policy preset in the network side device and the first TAU period, and then the third TAU period is issued to the user device by the device identifier of the user device.
The preset TAU period generation policy in the network side device may be to generate a third TAU period whose value is equal to the first TAU period, or to use a preset TAU period whose value is greater than or equal to the first TAU period in the network side device, or the like. And the network side device also carries the third TAU period to the user equipment through the TAU response message or the power-on attachment response message.
Specifically, as shown in fig. 3, in S301, the UE sends a TAU period negotiation request to the capability openness system, where the TAU period negotiation request includes a device identifier of the UE and a first TAU period; next, S302, the capability openness system forwards the TAU period negotiation request to the network side device; next, in step S303, the network side device generates a third TAU period according to a preset TAU period generation policy; next, S304, issue the generated third TAU period to the ue.
In addition, on the basis of the above embodiment of the present invention, the method further includes:
and if the first TAU period is the same as the second TAU period, determining the first TAU period as a target TAU period of the user equipment.
In this way, when the user equipment receives that the second TAU period of the network side equipment is the same as the first TAU period, it is known that the second TAU period of the network side equipment is applicable to the user equipment, and therefore, the first TAU period is determined as the target TAU period of the user equipment.
In summary, in the method for determining a tracking area update period according to the embodiment of the present invention, first, a first TAU period greater than a data transmission period of the first TAU period is sent to the network side device, so as to inform the network side device of the TAU period currently applicable to the ue. And then the user equipment receives a second TAU period sent by the network side equipment. Then, when the first TAU period is different from the second TAU period, that is, the set TAU period in the network side device is not applicable to the ue, the ue will request the network side device to issue the target TAU period of the ue. Therefore, the UE can request a new TAU period from the network side equipment when knowing that the TAU period set by the network side equipment is not applicable, so as to avoid an extra TAU flow when the TAU period set by the network side equipment is smaller than a data transmission period, thereby reducing the power consumption of the UE.
As shown in fig. 4, the method for determining a tracking area update period according to an embodiment of the present invention includes:
step 401, receiving a TAU period negotiation request sent by user equipment;
step 402, generating a third TAU period according to the TAU period negotiation request, where the third TAU period is greater than a data transmission period of the user equipment;
step 403, sending the third TAU period to the user equipment.
Through the above steps 401 to 403, after receiving the TAU period negotiation request sent by the ue and requesting the network side device to send a TAU period greater than the data sending period of the ue, the network side device applying the method for determining a tracking area update period according to the embodiment of the present invention generates a third TAU period applicable to the ue according to the TAU period negotiation request, and then sends the third TAU period to the ue. Therefore, the network side equipment can set an applicable TAU period for the user equipment according to the requirement of the user equipment, so as to avoid an extra TAU flow when the TAU period is smaller than the data transmission period, thereby reducing the power consumption of the user equipment.
In combination with the implementation of the user equipment in the practical application of the previous embodiment, a method of negotiating a request for a TAU period forwarded by the capability openness system is preferred, and step 401 includes:
receiving a TAU period negotiation request transmitted by the user equipment and forwarded by a capability development system; wherein the TAU period negotiation request includes the device identity of the user equipment and a first TAU period.
In order to ensure that the TAU period requested by the user equipment to the network side equipment is suitable for itself, the sent TAU period negotiation request includes the equipment identity of the user equipment and the first TAU period. Therefore, after the network side device generates the third TAU period, the network side device can complete the issuing of the third TAU period by carrying the third TAU period in the TAU response message or the power-on attachment response message sent by the user device through the device identifier of the user device.
In this embodiment, to generate the third TAU period applicable to the ue, step 402 includes:
and generating a third TAU period based on a preset TAU period generation strategy and the first TAU period.
It should be understood that, in the network side device to which the method of the embodiment of the present invention is applied, a specific TAU period generation policy is preset, and therefore, after receiving the TAU period negotiation request, a third TAU period is generated based on the preset TAU period generation policy and the first TAU period.
For example, the TAU period generation policy preset in the network side device may be that a third TAU period whose value is equal to the first TAU period is generated, and the third TAU period is generated directly from the received value of the first TAU period; the preset TAU period generation policy in the network side device may also be a preset TAU period whose value is greater than or equal to the first TAU period in the network side device, and the preset TAU period whose value is greater than or equal to the first TAU period is queried as the third TAU period in a plurality of TAU periods preset in the network side device. Of course, the TAU period generation strategy is not limited to the above, and will not be described herein.
It should also be appreciated that, before sending the TAU period negotiation request, as in the above embodiment, the user equipment sends the first TAU period, which is greater than the data sending period of the user equipment, to the network side equipment, so as to inform the network side equipment of the TAU period currently applicable to the user equipment. Thus, the method further comprises:
before receiving a TAU period negotiation request sent by the user equipment, if a first TAU period sent by the user equipment through a TAU message or a startup attachment message is received, sending a preset second TAU period to the user equipment.
Here, after receiving the first TAU period, the network side device informs the user equipment of the set second TAU period, so that the user equipment determines whether the TAU period set by the current network side device is applicable, that is, when the first TAU period is the same as the second TAU period, the user equipment subsequently uses the first TAU period to perform a TAU procedure; and if the first TAU period is different from the second TAU period, requesting the network side equipment to issue a new TAU period which is larger than the data sending period. The aim of avoiding the occurrence of an extra TAU flow when the TAU period set by the network side equipment is smaller than the data sending period and reducing the power consumption of the user equipment is fulfilled.
Corresponding to the mode that the user equipment sends the first TAU period through the TAU message or the power-on attachment message, the network side equipment sends the second TAU period through the TAU response message or the power-on attachment response message, and occupation of transmission resources is reduced.
In this embodiment, the network side device is preferably a mobility management entity MME of a core network.
In summary, in the method for determining a tracking area update period according to the embodiment of the present invention, after receiving a TAU period negotiation request sent by a ue, requesting a network side device to request to issue a TAU period, which is greater than a data transmission period of the ue, a third TAU period applicable to the ue is generated according to the TAU period negotiation request, and then the third TAU period is sent to the ue. Therefore, the network side equipment can set an applicable TAU period for the user equipment according to the requirement of the user equipment, so as to avoid an extra TAU flow when the TAU period is smaller than the data sending period, and reduce the power consumption of the user equipment.
It should be noted that, the tracking area update period determining method of the embodiment of the present invention is applied to a network side device, and is implemented by being matched with the tracking area update period determining method applied to a user equipment to determine a tracking area update period, so that in the implementation of the embodiment of the tracking area update period determining method applied to a user equipment, the implementation manner of the network side device is also applicable to the embodiment to achieve the same technical effect, and details are not repeated herein.
