Description

Wireless parameter adjusting method, node and computer storage medium

Technical Field

The present invention relates to wireless communication technologies, and in particular, to a wireless parameter adjustment method, a node, and a computer storage medium.

Background

Voice over LTE (VoLTE) based on IP Multimedia Subsystem (IMS) is an end-to-end service, and if the Discontinuous Reception (DRX) period of the calling or called side is simply adjusted, the entire VoLTE call quality cannot be well guaranteed. If the coverage of the calling UE is poor, configuring multiple TTI repetition for the UE so as to ensure the robustness; the coverage of the called UE is better, and the serving base station configures a longer DRX period for the UE so as to save power for the terminal. However, as a result, the end-to-end delay requirement of the VoLTE call may not be met, and thus the problems of delay, jitter, and the like of the VoLTE call still cannot be solved.

At present, no mechanism can guarantee the end-to-end VoLTE service quality.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The embodiment of the invention provides a wireless parameter adjusting method. Fig. 1 is a first flowchart illustrating a method for adjusting wireless parameters according to an embodiment of the present invention; as shown in fig. 1, the method includes:

step 101: the first node obtains a first duration; the first duration represents a duration from when the first information is sent from the first node to when the first information is received by an opposite end node opposite to the first node.

Step 102: and the first node sends the first duration to a second node.

In this embodiment, the first node is a UE, a base station, a P-GW, an SBC, a CSCF entity, or an MMTel AS. The second node being a base station, e.g. an evolved node B (eNB)

Taking the first node as the UE as an example, the first node may be a calling UE or a called UE; the opposite node may be a UE corresponding to the first node, for example, the first node is a calling UE, and the second node is a called UE; the correspondent node may also be a network element node associated with the corresponding UE; for example, the first node is a calling UE, and the second node may be a called network element node related to the called UE in a call process, such as a called SBC or a called CSCF associated with the called UE.

In this embodiment, the first duration represents a duration from when the first information is sent from the first node to when the first information is received by an opposite node opposite to the first node; as an example, if the first node is a calling UE and the opposite node is a called UE, a time period from the first information sent by the calling UE to the time when the called UE receives the first information is the first time period. As another example, taking the first node as the calling UE and the opposite node as the called SBC as an example, the time length from the first information sent by the calling UE to the time when the called SBC receives the first information is the first time length.

Based on this, the first time length obtained by the first node is sent to the second node, so that the second node reasonably configures the DRX configuration information or the coverage enhancement configuration information based on the actual transmission condition in the communication network characterized by the first time length or the actual delay condition in the communication network, thereby ensuring the transmission performance and the service quality of the communication network.

In an embodiment of the present invention, the sending, by the first node, the first duration to the second node includes: the first node transmits the first duration to a second node through a media access control unit (MAC CE) or through RRC signaling.

In an embodiment of the present invention, the sending, by the first node, the first duration to the second node includes: and the first node sends the first time length to a second node based on a preset period, or when the first node detects a preset event, the first time length is sent to the second node.

In this embodiment, as an embodiment, the act of reporting the first duration by the first node may be periodic, that is, the first duration is obtained based on a preset reporting period and is periodically sent. As another embodiment, the act of reporting the first duration by the first node may be triggered based on a detected preset event; the preset event may include one of the following events: comparing the detected first time length with a preset time length threshold value to exceed a preset threshold value; detecting that the air interface parameter modification preference parameter is updated to hope to adjust the non-connection receiving configuration information or the coverage enhancement configuration information; detecting that the second node requests the first duration, and so on.

In an embodiment of the present invention, when the first node is a UE, the method further includes: and the first node sends the air interface measurement result and/or the air interface parameter modification preference parameter to the second node.

In this embodiment, the air interface measurement result includes, but is not limited to, at least one of the following parameters: reference Signal Received Power (RSRP) Reference Signal Received Quality (RSRQ), Received Signal Strength Indication (RSSI), Signal to Interference plus Noise Ratio (SINR). The air interface parameter modification preference parameter represents non-connection receiving configuration information and/or coverage enhancement configuration information expected by the UE; as an example, the non-connection reception configuration information may be a DRX cycle (DRX cycle); the coverage enhancement configuration information may be.

How the first node obtains the first time length is described in detail below for different types of the first node.

As a first implementation manner, the obtaining, by the first node, a first duration includes: the first node detects the time length from the sending of the first SIP signaling to the receiving of the response signaling of the first SIP signaling, and determines the first time length based on the time length.

As an example, when the first node is a UE, the first SIP signaling may be INVITE signaling, PRACK signaling, or UPDATE signaling; the response signaling of the first SIP signaling may correspond to 183 signaling, first 200OK signaling, or second 200OK signaling, respectively.

Fig. 2 is a flowchart illustrating a first time duration obtaining method for adjusting radio parameters according to an embodiment of the present invention; as shown in fig. 2, UE a serves as a calling device, and UE B serves as a called device; the conversation process between the calling device and the called device can comprise the following steps:

step 201 to step 202: UE A sends request (INVITE) signaling to an AS server, and the INVITE signaling is used for requesting to establish call connection with UE B; the AS server sends an acknowledgement (100Trying) response signaling to UE a.

Step 203 to step 204: the AS server sends an INVITE signaling to the UE B, wherein the INVITE signaling is used for requesting to establish call connection with the UE B; UE B sends a 100Trying response signaling to the AS server.

Step 205 to step 206: UE B sends 183session progress (183session progress) signaling to AS server; the AS server sends 183session progress (183session progress) signaling to UE a.

Here, the INVITE signaling is used to request a media type and all coding schemes; the 183session progress signaling serves as a response signaling to the INVITE signaling, which includes supported media types and coding schemes.

Step 207 to step 208: UE A sends a temporary response (PRACK) signaling to an AS server; the AS server sends PRACK signaling to UE B.

Step 209 to step 210: UE B sends a first response (200OK) signaling to the AS server; the AS server sends a first 200OK signaling to UE a.

Here, the PRACK signaling is used for UE a and UE B to negotiate the media type and coding scheme, UE a starts resource reservation and notifies UE B through the PRACK signaling. The first 200OK signaling is used for confirmation of the negotiated media type and coding scheme, UE B initiates resource reservation and informs UE a.

Step 211 to step 212: UE A sends UPDATE (UPDATE) signaling to AS server; the AS server sends UPDATE signaling to UE B.

Step 213 to step 214: UE B sends a second 200OK signaling to the AS server; the AS server sends a second 200OK signaling to UE a.

Here, the UPDATE signaling indicates that the resource reservation of UE a as the calling terminal is completed; the second 200OK signaling indicates that the resource reservation of UE B as the called terminal is completed.

Step 215 to step 216: UE B sends 180Ringing (180Ringing) signaling to AS server; the AS server sends 180Ringing (180Ringing) signaling to UE A, at which time UE B, the called user, rings.

Step 217 to step 218: UE B sends a third 200OK signaling to the AS server; the AS server sends 200OK signaling to UE a.

Step 219 to step 220: UE A sends an Acknowledgement (ACK) response signaling to the AS server; the AS server sends an Acknowledgement (ACK) response signaling to UE B.

So far, UE a and UE B talk.

Step 221 to step 222: when UE A AS a calling user hangs up, UE A sends a hang-up (BYE) signaling to an AS server; and the AS server sends BYE signaling to the UE B.

Step 223 to step 224: UE B sends a fourth 200OK signaling to AS server; the AS server sends a fourth 200OK signaling to UE a.

In the above processing procedure, the first SIP signaling sent by the UE a serving as the calling terminal may be an INVITE signaling, and the response signaling corresponding to the INVITE signaling is a 183session progress signaling; or, the first SIP signaling may be a PRACK signaling, and a response signaling corresponding to the PRACK signaling is a first 200OK signaling; or, the first SIP signaling may be UPDATE signaling, and the response signaling corresponding to the UPDATE signaling is the second 200OK signaling.

The first SIP signaling sent by the UE B serving as the called terminal may be 183session progress signaling, and the response signaling corresponding to the 183session progress signaling is a PRACK signaling; alternatively, the first SIP signaling may be first 200OK signaling; the response signaling corresponding to the first 200OK signaling is UPDATE signaling; alternatively, the first SIP signaling may be third 200OK signaling, and the response signaling corresponding to the third 200OK signaling may be ACK signaling.

Based on this, the UE may detect a Time duration from the sending of the first SIP signaling to the receiving of the response signaling of the first SIP signaling by setting a timer, and since the Time duration is a Round-Trip Time (RTT), the first Time duration may be determined by averaging (e.g., dividing by 2) based on the Time duration. As another embodiment, when the first node is a UE, the first duration may also be a duration from sending the first SIP signaling to receiving a response signaling of the first SIP signaling.

In another embodiment, the UE may also detect a duration from the initiation of the first SIP signaling to the reception of the response signaling of the nth SIP signaling, and determine the first duration based on the duration. For example, if UE a measures a duration from sending the INVITE signaling to receiving the second 200OK, which is three RTTs in the process, averaging may be performed based on the duration, for example, averaging is divided by 3, and a duration corresponding to one RTT may be determined; also for example, the average is divided by 6, and the first duration may be determined.

In another embodiment, if the first node is another network element device, such as an SBC, fig. 3 is another schematic flow chart of obtaining the first time length in the radio parameter adjustment method according to the embodiment of the present invention; as shown in fig. 3, a signaling interaction schematic for each network element device after initiating an INVITE signaling for a UE as a calling terminal may specifically include:

step 31: the UE initiates INVITE signaling to the SBC.

Step 32 to step 35: SBC sends AAR signaling to PCRF; PCRF sends RAR signaling to SAE GW; SAE GW sends RAA signaling to PCRF; the PCRF sends AAA response signaling to the SBC.

Here, the SBC may determine the first time length based on a time length from when the AAR signaling is issued to when the AAA response signaling is received. Wherein, the SBC may send the first time duration to the base station as the second node through the P-GW.

Step 36 to step 37: the SAE GW sends a Create Bearer Request (Create Bearer Request) to the MME, and an air interface flow is executed between the MME and the UE.

Step 38: the MME sends a Create Bearer Response (Create Bearer Response) to the SAE GW.

As another implementation manner, fig. 4 is a schematic flow chart illustrating obtaining a first time duration in a wireless parameter adjustment method according to an embodiment of the present invention; AS shown in fig. 4, the call process of ue (O) AS the calling terminal and ue (T) AS the called terminal is distinguished in that part of the network element devices of the parameter call process is also included in this example, including calling SBC (O)) and called SBC (T)), calling CSCF (O)) and calling CSCF (T)), calling MMTel AS (O)) and called MMTel AS (T)), and so on; the CSCF in this example is a querying CSCF (I-CSCF) or a Serving CSCF (S-CSCF). This example may specifically include:

step 401 to step 418: ue (o) sends INVITE signaling, which reaches ue (t) via network element equipment shown in the figure; ue (t) sends 183 signaling to ue (o).

In this process, for each network element device on the calling side, the time period from the reception of the INVITE signaling to the reception of the 183 signaling may be detected, and the first time period may be determined based on the time period.

Step 419: ue (o) sends PRACK signaling or first 200OK signaling to ue (t).

Step 420 to step 437: ue (o) sends UPDATE signaling, which reaches ue (t) via the network element equipment shown in the figure; ue (t) sends a second 200OK signaling to ue (o).

In this process, for each network element device of the calling side, a time period from the reception of the UPDATE signaling to the reception of the second 200OK signaling may be detected, and the first time period is determined based on the time period.

Steps 438 to 439: UE (T) sends 180Ringing signaling to UE (O); ue (o) sends a third 200OK signaling to ue (t), at which time the call between ue (o) and ue (t) is established.

After that, if the ue (o) is on-hook, the ue (o) sends an on-hook (BYE) signaling to the ue (t) through the network element equipment; ue (t) sends a fourth 200OK or ACK signaling to ue (o).

In the above solution, for the called network element device, the first time length may be determined based on a time length from receiving the response signaling of the first signaling to receiving the second signaling. For example, sbc (t) detects a time period from the reception of 183 signaling to the reception of UPDATE, and determines the first time period based on the time period.

AS a second implementation manner, when the first node is an SBC, a CSCF entity, or an MMTel AS, the obtaining, by the first node, a first duration includes: the first node determines the number of intermediate nodes transmitted by the second SIP signaling based on the value carried by the maximum jump digit field in the received second SIP signaling and a preset initial value of the maximum jump digit field, and determines the first time length based on the number of the intermediate nodes.

In this embodiment, the header of each SIP signaling carries a maximum hop count (MAX-FORWARD) field, which indicates the maximum hop count. The number of the maximum hop turns represented by the field is reduced by 1 when the SIP signaling passes through each node; when the maximum hop count is changed to 0, if the SIP signaling does not reach the opposite UE, the SIP signaling will be discarded. The initial value of the maximum hop number of the SIP signaling is configured in advance.

The SBC, the CSCF entity, or the MMTel AS may determine the number of intermediate nodes for transmission of the second SIP signaling based on the value carried by the maximum hop number field and a preset initial value of the maximum hop number field, and determine the transmission duration of the second SIP signaling, that is, the first duration, based on the number of intermediate nodes and the average duration of the SIP signaling passing through each node. For example, the scheme of the present embodiment may determine the transmission time length between sbc (t) and sbc (o), or the transmission time length between ue (t) and sbc (o), and so on.

In this embodiment, the SBC, CSCF entity, or MMTel AS sends the determined first time length to the P-GW through the SGi port, and then the P-GW sends to the second node (i.e., base station); in this way, the base station obtains the transmission condition of the air interface and the network transmission condition, so that the receiving configuration information and/or the coverage enhancement configuration information can be better adjusted.

In another embodiment, after the first node determines the number of intermediate nodes transmitted by the second SIP signaling based on a value carried by a maximum number of hops in the received second SIP signaling and a preset initial value of the maximum number of hops, the method further includes: and the first node sends the number of the intermediate nodes to the second node so that the second node determines a first time length based on the number of the intermediate nodes.

As a third implementation manner, when the first node is a UE, a base station, or a P-GW, the obtaining, by the first node, a first duration includes: the first node determines a first time length based on a first time parameter of sending a first detection packet and a second time parameter of receiving a second detection packet corresponding to the first detection packet; the second detection packet is sent by a corresponding node corresponding to the first node; the second probe packet is the same as or different from the first probe packet. Or the first node determines a first time length based on a first time parameter of a first detection packet and a second time parameter carried by a second detection packet corresponding to the first detection packet; the second detection packet is sent by a corresponding node corresponding to the first node; the second time parameter represents the time when the opposite end node receives the first detection packet

In this embodiment, when the first node is a UE, a base station, or a P-GW, and when the UE, the base station, or the P-GW is involved, a probe packet (denoted as a first probe packet) is added to the sent data, where the first probe packet carries a first timestamp when the probe packet is added; as a first implementation manner, when a UE, a base station, or a P-GW of an opposite end receives a first probe packet, replying the first probe packet, where the content of the replied first probe packet is unchanged, it can be understood that the replied probe packet is denoted as a second probe packet, and the content of the second probe packet is the same as or different from that of the first probe packet, that is, the content of the second probe packet is the same as or different from that of the first probe packet; the UE, the base station, or the P-GW may determine the first duration based on a duration between receiving the second timestamp of the second sounding packet and the first timestamp carried in the first sounding packet. As a second embodiment, the replied second probing packet records a first timestamp of the UE, the base station, or the P-GW of the opposite end receiving the first probing packet; the UE, the base station, or the P-GW may determine the first duration based on a duration between receiving the second timestamp of the second sounding packet and the first timestamp carried in the first sounding packet.

In this embodiment, if the first node is a UE, the first probe packet may be added to the RTP; if the first node is a base station or a P-GW, a first probe packet can be added to a GTP-U.

In this embodiment, the UE or the P-GW sends the determined first time length to the second node (i.e., the base station); in this way, the base station obtains the transmission condition of the air interface and the network transmission condition, so that the receiving configuration information and/or the coverage enhancement configuration information can be better adjusted.

In practical applications, RTCP packets may be classified into five categories, namely, receiver report packet (RR), source report packet (SR), source description packet (SEDS), leave declaration (BYE), and application specific packet (APP), according to different control information carried. The main contents of the SR packet are: SSRC of the corresponding RTP stream, timestamp of the newly generated RTP packet in the RTP stream and NTP, the number of packets contained in the RTP stream, and the number of bytes contained in the RTP stream. The NTP Timestamp (Network time protocol) indicates an absolute time value when the SR packet is transmitted. NTP serves to synchronize the different RTP media streams.

In this embodiment, the UE may calculate a time duration between the second time parameter indicated by the NTP Timestamp field in the RTCP information and the first time parameter of the RTCP information received, and determine the first time duration. Further feeding back the first time length to a second node (namely a base station); in this way, the base station obtains the transmission condition of the air interface and the network transmission condition, so that the receiving configuration information and/or the coverage enhancement configuration information can be better adjusted.

Based on the foregoing embodiments, the embodiment of the present invention further provides a wireless parameter adjusting method. Fig. 5 is another flowchart illustrating a method for adjusting radio parameters according to an embodiment of the present invention; as shown in fig. 5, the method includes:

step 301: the second node receives the first duration from the first node; the first duration represents a duration from when the first information is sent from the first node to when the first information is received by an opposite end node opposite to the first node.

Step 302: and the second node adjusts the non-connection receiving configuration information and/or the coverage enhancement configuration information of the UE associated with the first node according to the first time length.

In an embodiment, the method further comprises: the second node receives the number of intermediate nodes from the first node, and determines a first duration based on the number of intermediate nodes.

In this embodiment, a maximum hop count (MAX-FORWARD) field indicating the maximum hop count is carried for each header of the SIP signaling. The number of the maximum hop turns represented by the field is reduced by 1 when the SIP signaling passes through each node; when the maximum hop count is changed to 0, if the SIP signaling does not reach the opposite UE, the SIP signaling will be discarded. The initial value of the maximum hop number of the SIP signaling is configured in advance. The first node may determine the number of intermediate nodes for the second SIP signaling transmission based on the value carried by the maximum hop number field and a preset initial value of the maximum hop number field; the number of intermediate nodes of the second node and the average time length of the SIP signaling passing through each node determine the transmission time length of the second SIP signaling, namely the first time length.

Based on this, the first time length obtained by the first node is sent to the second node, so that the second node reasonably configures the non-connection receiving configuration information or the coverage enhancement configuration information based on the actual transmission condition in the communication network characterized by the first time length or the actual delay condition in the communication network, thereby ensuring the transmission performance and the service quality of the communication network.

In one embodiment of the invention, the method further comprises: and the second node receives the air interface measurement result and/or the air interface parameter modification preference parameter of the UE. In this way, the second node obtains the transmission condition of the air interface and the network transmission condition, so that the receiving configuration information and/or the coverage enhancement configuration information can be better adjusted.

In an embodiment of the present invention, the adjusting, by the second node, the non-connection reception configuration information or coverage enhancement configuration information of the UE associated with the first node according to the first time length includes: and the second node adjusts the non-connection receiving configuration information or the coverage enhancement configuration information of the UE associated with the first node according to at least one of the first duration, the air interface measurement result and the air interface parameter modification preference parameter. The UE associated with the first node is specifically a UE reporting the first duration, or may also be a UE reporting an air interface measurement result and/or an air interface parameter modification preference parameter.

As an implementation manner, the adjusting, by the second node, the non-connection reception configuration information or coverage enhancement configuration information of the UE associated with the first node according to at least one of the first duration, the air interface measurement result, and the air interface parameter modification preference parameter includes: when the first time length is smaller than a first threshold and the air interface quality represented by the air interface measurement result meets a preset condition, configuring a first discontinuous reception cycle exceeding a second threshold for the UE; when the first time length exceeds a third threshold and the air interface quality represented by the air interface measurement result meets a preset condition, configuring a second discontinuous reception cycle which is not greater than a fourth threshold for the UE; and when the air interface quality represented by the air interface measurement result does not meet the preset condition, configuring a preset number of data retransmission times for the UE.

For example, when the first duration is short and the air interface measurement result is good, a long DRX cycle is configured for the UE, so that the UE can save power; when the first time length is long and the air interface measurement result is good, configuring a short DRX period for the UE so as to meet the end-to-end time delay requirement; and when the air interface measurement result is poor, considering the end-to-end delay condition, and configuring multiple data retransmission for the UE.

As another embodiment, the adjusting, by the second node, the non-connection reception configuration information or coverage enhancement configuration information of the UE associated with the first node according to at least one of the first duration, the air interface measurement result, and the air interface parameter modification preference parameter includes: when the air interface parameter modification preference parameter represents that a discontinuous reception cycle is prolonged, modifying the preference parameter according to the air interface parameter to prolong the discontinuous reception cycle or not to adjust the discontinuous reception cycle based on a judgment result that whether the adjusted discontinuous reception cycle meets the requirement of the first duration; when the air interface parameter modification preference parameter representation shortens a discontinuous reception cycle, if the adjusted discontinuous reception cycle does not meet the requirement of the first duration and the air interface measurement result meets a preset condition, shortening the discontinuous reception cycle, wherein the shortened discontinuous reception cycle is shorter than the discontinuous reception cycle of the air interface parameter modification preference parameter representation; and if the adjusted discontinuous receiving period meets the requirement of the first time length, modifying the preference parameter according to the air interface parameter to shorten the discontinuous receiving period.

As an example, if the air interface parameter modifies the preference parameter to be expected to increase the DRX cycle so as to reduce the power consumption of the terminal, then:

1) the base station considers that if the air interface duration is increased, the requirement of VoLTE end-to-end time cannot be met (namely the requirement of the first duration cannot be met), the base station does not prolong a DRX period for the UE or configure a shorter DRX period for the UE;

2) when the base station considers that the VoLTE end-to-end time requirement can be well met (i.e. the requirement of the first duration can be met), a DRX cycle that the UE tends to or a longer DRX cycle is configured for the UE, that is, the DRX cycle configured in the preference parameter is modified according to the air interface parameter.

As another example, if the air interface parameter modifies the preference parameter to hope to shorten the DRX cycle in order to shorten the overall end-to-end delay, then:

1) when the base station considers that the DRX period inclined by the UE cannot meet the VoLTE end-to-end time requirement (namely cannot meet the requirement of the first duration), and the air interface quality of the UE is good, and a shorter DRX period can be configured for the UE, namely the DRX period shorter than the expected DRX period in the air interface parameter modification preference parameter can be configured;

As another embodiment, if the air interface parameter modifies the preference parameter to be expected to increase the coverage enhancement related configuration to enhance the link reliability, then:

1) when the base station considers that the coverage enhancement configuration (TTI repetition times) which is inclined by the UE cannot meet the requirement of VoLTE end-to-end time, and the UE air interface quality is good and a shorter DRX period can be configured, the base station configures the shorter DRX period for the UE;

2) when the base station considers that the VoLTE end-to-end time requirement can be well met, the UE will be configured with a UE-intended DRX cycle or a longer DRX cycle.

In other embodiments, the second node adjusts the DRX cycle and/or the coverage enhancement configuration information based on the first duration, the air interface measurement result, and the air interface parameter modification preference parameter as a whole to meet the end-to-end delay requirement.

In another embodiment, the second node may further adjust the air interface parameter modification preference parameter based on the first duration and the air interface measurement result, so as to meet the end-to-end delay requirement.
