Description
Technical Field
The invention relates to the technical field of communication, in particular to a method and a device for establishing a Qci2 video special bearer.
Background
The video color ring is a special service of a Long-Term Evolution Voice bearer (Voice Over Long-Term Evolution, hereinafter abbreviated as VOLTE), and develops a "heard color ring" into a "watched color ring". A user dials a voice call or a video call under the VOLTE network, and a piece of video content can be seen before the call is connected. The video color ring user can make or upload personalized video content, or select from a video library of an operator, and can set different video content aiming at different calling parties.
The conventional video color ring back tone service normal flow is premised on that a calling party opens a VOLTE, and is in a Long Term Evolution (LTE) network and IP Multimedia System (IMS) registration state, and the called party opens a video color ring back tone service. Fig. 1 is a normal flow chart of an existing video color ring service, as shown in fig. 1, a first half call connection flow of the existing video color ring service is consistent with a general VOLTE call flow, and only when a called party rings and feeds back a ring (180Ringing) to a called color ring server, the called color ring server intercepts 180Ringing, completes an early media negotiation with a calling party through update, plays the video color ring service for the calling party, after a called party answers, an answer session is successful (200ok), and is intercepted again by the called color ring server, the called color ring server completes the early media negotiation with the calling party through update, modifies a media source to be called receiving and sending, and after the negotiation is completed, the called color ring server forwards 200ok (for invite) to the calling party, and finally completes a call connection. The video color ring is that the color ring platform transmits the video streaming media to the calling side through the special bearer of Quality of Service Class Identifier (Qci) 2 established by the calling, and the bearer opening point of the video color ring completes the special bearer of Qci2 for the calling. When the called party responds actively, the end point is that the called polyphonic ringtone platform intercepts a called feedback response 200ok (for update) and sends update (update early media source) to the calling party, after receiving the update, a calling side Session Border Controller (SBC) device triggers a Policy and Charging Rules Function unit (Policy and Charging Rules Function, PCRF) and deletes a Qci2 dedicated bearer, when the called party does not respond, the Qci2 bearer is kept until the core network is overtime, the bearer is removed, when the called party rejects the response, the Qci2 bearer is kept until the core network knows that the called party rejects the call and actively removes the link, so the calling side keeps the Qci2 dedicated bearer during the period, the called server informs the calling side of the downstream bandwidth guarantee 960 for the Qci2 bandwidth requirement through the update that the polyphonic ringtone is kbps, after the calling side establishes the Qci2 and the called party does not answer or if the called party rejects the called party, then the core network instructs to tear down the link), the wireless network at the calling side needs to maintain dedicated qos bearer with downlink bandwidth requirement of 960kbps, and if the user is located at a point where the wireless environment is excellent, that is, the Signal to Interference plus Noise Ratio (SINR) value is high, Qci2 ensures that the bandwidth enables high coding, and occupies less Physical Resource Block (PRB) resources.
However, if the user is located at a very bad point of the wireless environment, i.e. the SINR value is low, the Qci2 guarantees that the bandwidth enables low coding and occupies more PRB resources. In the process of establishing the Qci2 dedicated bearer, since the Qci2 is Guaranteed Bit Rate (GBR) service, the bearer establishment process can preempt the Qci9 service, which is generally China Mobile internet (CMNET) data service. Once a plurality of poor quality calling users in the same cell call the video color ring users, a large amount of network resources are occupied, so that the original data service users cannot be scheduled, and even the original data service users are disconnected.
Therefore, how to ensure that the calling subscriber does not occupy a large amount of network resources when the system resources are busy and the wireless environment is poor is a problem to be solved urgently.

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 2 is a flowchart of a method for establishing a Qci2 dedicated video bearer according to an embodiment of the present invention, and as shown in fig. 2, the method includes:
s201: receiving a service quality grade identification Qci2 video special bearer establishment request issued by a service gateway SGW, and refusing to establish a Qci2 video special bearer if judging that system resources and a calling user terminal meet matching conditions according to the Qci2 video special bearer establishment request;
wherein the matching condition includes: the system resources are busy and the calling subscriber terminal is in a weak coverage area.
The service Gateway (Serving Gateway, hereinafter referred to as SGW) is an important network element in a mobile communication network, and may be configured to issue a Qci2 video dedicated bearer establishment request.
The Qci2 dedicated bearer is a bearer dedicated to the video service in the early media delivery video ring back tone.
The calling user terminal is a user who initiates voice telephone or video telephone under the VOLTE network.
The weak coverage area represents an area where the wireless environment is poor.
Specifically, a calling user opens the VOLTE and is in an LTE network and IMS registration state, a called user opens the video color ring service, and a first half call continuing flow of the video color ring flow is consistent with a common VOLTE call flow, including: the calling party initiates a call to the called party (invite), the called party replies to the calling party for a session (status code 183), the calling party replies an acknowledgement (PRACK) to the status code 183, the called party replies that the PRACK session is successful (200ok for PRACK), the calling party sends update, and the called party replies that the update session is successful (200ok for update). When a called party rings and feeds back 180 rings and then arrives at a called color ring server, the called color ring server intercepts 180 rings, the color ring server sends Update to a calling SBC, the calling SBC instructs a calling terminal to establish Qci2 private bearer through PCRF, the calling terminal feeds back 200ok for Update to the called color ring server, and when a Qci2 video private bearer device receives a Qci2 video bearer establishment Request sent by an SGW, a system resource judgment and calling terminal wireless environment judgment flow is added, if the system resource is in a busy state, namely the available system resource is insufficient, and the calling user terminal is in a weak coverage area, namely an area with poor wireless environment, the Qci2 video private bearer device replies a Qci2 video private bearer establishment failure message to the SGW, the SGW forwards a private bearer establishment result to the PCRF through a Re authorization Request (Re Aurequest, hereinafter referred to as RAR) message forwards the Qci2 dedicated bearer establishment result to the calling SBC. The calling SBC feeds back update (curr local none) to the called color ring server, and represents that the calling terminal does not finish the establishment of the special bearer. The called color ring server replies 200ok for update, which represents that the special bearer establishment of calling Qci2 is failed. The called color ring server feeds back a called response 200ok for invite message to the calling party, the calling party replies an Acknowledgement Character (ACK) to the called party, and the calling is continued.
The embodiment of the invention provides a method for establishing a Qci2 video special bearer, which judges whether to establish the Qci2 video special bearer or not by setting a system resource judgment process and a calling terminal wireless environment judgment process, ensures that a calling user in a poor wireless environment refuses to establish the Qci2 special bearer when the system resource is busy, greatly reduces the consumption of network resources, avoids network congestion and reduces the possibility of disconnection of a data service user.
Further, on the basis of the above embodiment of the present invention, the system resource being in a busy state includes:
the number of the RRC connections of the cell is larger than a first threshold value, and the utilization rate of the PRB is larger than a second threshold value.
The cell radio resource control is a control mechanism for exchanging configuration information and achieving an agreement within a cell.
The physical resource block PRB corresponds to 12 continuous carriers in the frequency domain, and a time-series (half a subframe, 0.5ms) resource in the time domain.
Specifically, when the Qci2 video special bearer is established to receive a Qci2 video bearer establishment request issued by an SGW, a system resource judgment and calling terminal wireless environment judgment process is added, if the Qci2 video special bearer is established to receive a Qci2 video bearer establishment request issued by the SGW, a system resource judgment and calling terminal wireless environment judgment process is added, if the system resource is in a busy state, that is, available system resources are insufficient, specifically, the number of cell radio resource control RRC connections in the busy state of the system resource is greater than a first threshold, and the downlink physical resource block PRB utilization rate is greater than a second threshold, wherein the first threshold and the second threshold can be reasonably set according to actual conditions. For example, the first threshold is set to 100, the second threshold is set to 40%, when the RRC connection number is greater than 100 and the utilization rate of the physical downlink resource block PRB is greater than 40%, the system resources are in a busy state, in addition, the calling user terminal is in a weak coverage area, that is, an area with a poor radio environment, the Qci2 video dedicated bearer device replies a Qci2 video dedicated bearer establishment failure message to the SGW, that is, the available resources of the system are insufficient, and the calling user terminal is in a weak coverage area, that is, an area with a poor radio environment, the Qci2 video dedicated bearer device replies a Qci2 video dedicated bearer establishment failure message to the SGW.
The embodiment of the invention provides a method for establishing a Qci2 video special bearer, wherein in the method, when the connection number of a cell radio resource control RRC is greater than a first threshold value and the utilization rate of a physical downlink resource block PRB is greater than a second threshold value, the system resource is determined to be in a busy state, the use condition of the system resource can be known more clearly, and the subsequent reasonable distribution of the system resource is facilitated.
Further, on the basis of the above embodiment of the present invention, the calling user terminal being in a weak coverage area includes:
and the Reference Signal Received Power (RSRP) value is smaller than a third threshold value, and the RSRP value is determined according to the uplink path loss and the signal quality of the user terminal.
The Reference Signal Received Power (RSRP) is a key parameter representing the strength of a wireless signal in an LTE network.
The uplink loss represents a loss generated by radio waves propagating in a space when the terminal transmits uplink.
Specifically, when a Qci2 video special bearer is established to receive a Qci2 video bearer establishment request issued by an SGW, a system resource judgment and calling terminal wireless environment judgment process is added, if the Qci2 video special bearer is established to receive a Qci2 video bearer establishment request issued by an SGW, a system resource judgment and calling terminal wireless environment judgment process is added, a calling user terminal is in a weak coverage area, namely an area with poor wireless environment, in detail, an RSRP value is determined according to uplink path loss and signal quality of the user terminal, when a reference signal receiving power RSRP value is greater than a third threshold value, the calling user terminal is in the weak coverage area, wherein the third threshold value can be reasonably set according to actual conditions, such as-110 dBm, when the reference signal receiving power RSRP value of the calling user terminal is less than-110 dBm, the calling user terminal is in the weak coverage area, meanwhile, when the system resources are in a busy state, that is, the available system resources are insufficient, the Qci2 video dedicated bearer device replies a Qci2 video dedicated bearer establishment failure message to the SGW, that is, the available system resources are insufficient, and the calling user terminal is in a weak coverage area, that is, an area with poor wireless environment, then the Qci2 video dedicated bearer device replies a Qci2 video dedicated bearer establishment failure message to the SGW.
The embodiment of the invention provides a method for establishing a Qci2 video special bearer, wherein in the method, when the Reference Signal Received Power (RSRP) value is smaller than a third threshold value, a calling user terminal is determined to be in a weak coverage area, so that the wireless environment condition of the position of the calling user terminal can be more clearly understood, and whether the Qci2 video special bearer is established or not can be better determined.
Further, on the basis of the foregoing embodiment of the present invention, after the rejecting establishment of the Qci2 dedicated video bearer, the method further includes:
and feeding back a Qci2 video special bearer establishment failure message to the color ring server through the SIP message so as to enable the color ring server to degrade the color ring service into the audio service.
The SIP messages are text-based application-layer control protocols for creating, modifying, and releasing messages for one or more participants' sessions.
Specifically, after the apparatus for establishing the Qci2 video dedicated bearer refuses to establish the Qci2 video dedicated bearer, the apparatus feeds back the establishment failure of the dedicated bearer of the polyphonic ringtone server through a Session Initiation Protocol (SIP) message, after the polyphonic ringtone server knows, the video polyphonic ringtone service, including the Qci2 video service and the Qci1 audio service, is a single audio polyphonic ringtone, that is, the Qci1 audio service, and the subsequent processes are continued according to the audio polyphonic ringtone process.
In the method, an SIP message is used for feeding back a Qci2 video special bearer establishment failure message to a color ring server so that the color ring server can degrade color ring services into audio services, a calling user in a poor wireless environment can be ensured to refuse to establish the Qci2 special bearer when system resources are busy, consumption of network resources is greatly reduced, the client can be better served in the form of audio color ring, and user experience is improved.
Fig. 3 is a specific flowchart of a method for establishing a Qci2 dedicated video bearer, fig. 4 is a judgment diagram of a specific flowchart of a method for establishing a Qci2 dedicated video bearer, and as shown in fig. 3 and fig. 4, the specific flowchart of the method for establishing a Qci2 dedicated video bearer includes thirteen steps as follows:
the method comprises the following steps: the VOLTE call normal flow includes a calling invite, a called status code 183, a calling prack, a called 200ok for prack, a calling update, and a called 200ok for update.
Step two: the called party rings and feeds back 180 ring.
Step three: after the called color ring server (color ring AS) receives 180ring of the called party, the called party opens the video color ring service, the called color ring intercepts 180ring, and sends Update to the calling SBC, and the calling SBC instructs the calling terminal to establish the Qci2 private bearer through the PCRF.
Step four: the calling party feeds back 200ok for update to the called color ring AS.
Step five: when the device for establishing the Qci2 video special bearer receives a Qci2 video bearer establishment request sent by an SGW, a system Resource judgment and calling terminal wireless environment judgment process is added, namely, whether the terminal is in a weak coverage area (below RSRP-110 dBm) or Not is judged according to the cell RRC connection number, the utilization rate of downlink resources Prb, the uplink path loss and the quality, if the system Resource is busy and the calling is in a wireless quality environment, the device for establishing the Qci2 video special bearer replies a bearer establishment failure message E-RAB SETUP RESPONSE (cause: Radio Resource Not available) to the SGW to the core network, the SGW forwards a special bearer establishment result to the PCRF through the CCR-U, and the PCRF forwards the Qci2 special bearer establishment result to the calling SBC through a message.
Step six: the calling SBC feeds back update (curr local none) to the called color ring AS side to represent that the calling terminal does not finish the establishment of the special bearer.
Step seven: the called color ring AS replies 200ok for update, which represents that the special bearer establishment of calling Qci2 is failed.
Step eight: and after receiving the bearer establishment rejection of the calling side Qci2, the called color ring AS degrades the original video color ring service into an audio color ring service and sends 180ring to the called side.
Step nine: and the called party responds, and sends 200ok for invite to the called color ring AS.
Step ten: the called color ring AS intercepts the called response 200ok message, and negotiates with the calling SBC to update the early media route of the calling party and the called party through update.
Step eleven: the caller replies 200ok for update.
Step twelve: the called color ring AS feeds back a called response 200ok for invite message to the calling party.
Step thirteen: the calling party replies ACK to the called party, and the calling is finished and connected.
In the method for establishing the Qci2 dedicated video bearer according to this embodiment, before the apparatus for establishing the Qci2 dedicated video bearer establishes a video bearer (Qci is 2, which is specially used for video service in early media delivery video ring back tone), the apparatus for establishing the Qci2 dedicated video bearer determines the cell busy/idle degree, the terminal signal quality RSRP (weak coverage)/the signal to noise ratio SINR (high interference), and if the system resource is busy and the calling radio environment is poor, the apparatus for establishing the Qci2 dedicated video bearer rejects the establishment of the video bearer. And the special bearer establishment failure of the polyphonic ringtone AS is fed back through the SIP message, after the polyphonic ringtone AS is known, the video polyphonic ringtone (comprising Qci2 video service and Qci1 audio service) is changed into a single audio polyphonic ringtone (Qci1 audio service), and the subsequent flow is continued according to the audio polyphonic ringtone flow.
The method ensures that the calling subscriber in poor wireless environment refuses to establish the Qci2 special bearing when the system resource is busy. The possibility of network congestion caused by a large amount of consumed network resources and even the possibility of disconnection of data service users is reduced.
