Description
Technical Field

Background
In the Long Term Evolution (LTE) Voice (Voice over LTE) technology and Single Radio Voice Call Continuity (SRVCC) technical solutions of the current universal Mobile communication technologies, when a base station determines that a User Equipment (UE) needs to send a Network handover request (handover required) message to a Mobile Management Entity (MME) when the base station determines that the UE needs to send a dedicated Voice bearer to the Global System for Mobile Radio Access Network (GERAN) from an LTE Network and the base station currently has the dedicated Voice bearer for the Voice over LTE, a SRVCC procedure is triggered to perform Network handover.
In general, the triggering of such SRVCC procedures is reasonable. However, in some special cases, although the VoLTE call is ended and all network elements in an IP Multimedia Subsystem (IMS) domain have completed session release, due to a problem of cooperation between an Evolved Packet Core (EPC) system, a Policy Control and Charging (PCC) system and an LTE system, a phenomenon of "voice dedicated bearer drop" may occur because a voice dedicated bearer established for the VoLTE call is not released normally. The occurrence of this phenomenon will result in invalid SRVCC network handover, which in turn affects SRVCC performance, affects services, and occupies radio resources of GERAN networks.

Detailed Description
Features and exemplary embodiments of various aspects of the present invention will be described in detail below, and in order to make objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
At present, if a voice dedicated bearer established by a User Equipment (UE) after a previous VoLTE call is ended is not normally released (that is, a phenomenon of "voice dedicated bearer falling dead" occurs), a subsequent base station (eNodeB) carries a cell "srvcchoidentity: csonnly" in a handover required message sent to an MME when it is determined that the UE needs to be switched from an LTE network to a GERAN network, thereby prompting that an SRVCC procedure needs to be triggered. After receiving the handover required message, the MME sends a Request (PS to CS Request) for handover from a Packet Switching domain (PS) to a Circuit Switching domain (CS) to an SRVCC network interworking unit (SRVCC IWF). After receiving the PS to CS Request, the SRVCC IWF completes the handover procedure of the GERAN network side according to the specified SRVCC procedure, and then sends a handover command (handover command) to the eNodeB through the MME, thereby requesting the eNodeB to perform handover to the GERAN network side. At this time, the eNodeB immediately sends a handover cancel message to the MME, and this time, the SRVCC is cancelled by the eNodeB and ends.
The occurrence of this phenomenon will lead to the following consequences:
1. affecting SRVCC performance. Once the phenomenon of 'voice dedicated bearer drop death' occurs, unless the UE performs detach/attach operation, the voice dedicated bearer will exist in the eNodeB for a long time, so during the voice dedicated bearer drop death, the UE can easily and frequently initiate a large number of SRVCC requests, and all SRVCC requests all fail to cancel without exception, which inevitably causes the SRVCC performance to drop dramatically.
2. Affecting the service. The reason why the eNodeB initiates the handover request is to ensure that the original service (typically, data access service) of the UE is continuous and uninterrupted, but the original data service is forced to be interrupted and cannot be switched to the GERAN network for continuous use all the time due to the false triggering of the SRVCC procedure (SRVCC does not support simultaneous handover of data services).
3. Occupying radio resources of the GERAN network. And the target GERAN cell allocates corresponding wireless channel resources for the SRVCC process which is triggered by mistake because the voice special bearer is dead. The large number of frequent invalid SRVCC requests would unnecessarily consume a large amount of valuable radio channel resources.
In order to solve the foregoing problems, embodiments of the present invention provide a method, an apparatus, a device, and a storage medium for processing a dedicated voice bearer, so as to improve SRVCC performance, and reduce occupation of radio resources of a GERAN network and influence on a service.
As shown in fig. 1, fig. 1 is a flowchart illustrating a method for processing a dedicated voice bearer according to an embodiment of the present invention. The voice dedicated bearer processing method may include:
s101: and detecting the number of the received message pairs according to a preset detection rule.
The message pair comprises a network handover required message of the identification information of the user equipment and a network handover cancel message corresponding to the network handover required message.
S102: and if the detection result meets the preset session state request rule, acquiring the session state of the user equipment.
S103: and if the session state is a no-session state, sending a voice special bearer deactivation request to the base station and sending a voice special bearer deletion request to the system architecture evolution gateway so as to delete the voice special bearer.
The system architecture evolution Gateway (SAE-GW) is a generic name of a Serving Gateway (SGW) and a Packet Data Network Gateway (PGW).
In an embodiment of the present invention, the Identification information of the ue may be an International Mobile Equipment Identity (IMEI), an International Mobile Subscriber Identity (IMSI), and a Mobile station International ISDN Number (MSISDN). Among these, IMSI is also commonly referred to as: the mobile phone serial number, the mobile phone serial number and the mobile phone serial number; briefly, the MSISDN is the mobile phone number.
In one embodiment of the invention, the session state includes: no conversation, before ringing, during ringing and during conversation, etc.
In one embodiment of the present invention, the preset detection rule may be to perform detection at intervals. Based on this, according to the preset detection rule, detecting the number of the received message pairs may include: and detecting whether the number of the received message pairs in the preset time period is not less than a first preset message pair number threshold value or not every other preset time period, and if the number of the message pairs is not less than the first preset message pair number threshold value, indicating that the detection result meets the preset session state request rule.
For example, the preset time period is 1 hour, and the first preset message pair quantity threshold is 60 hours. Detecting whether the number of the message pairs received in 1 hour is not less than 60 every other hour, and if the number of the detected message pairs is not less than 60, acquiring the session state of the user equipment.
It is understood that, at every preset time interval, whether the number of the received message pairs in the preset time interval is not less than the first preset message pair number threshold is detected, a timer may be set to time, and a counter may be set to count the number of the message pairs. And when the timing time of the timer reaches the time corresponding to the preset time period, resetting the timer and the counter to zero, and timing and counting again.
In one embodiment of the invention, a timer and a counter are started when a first message pair is received, wherein the timer starts timing and the counter starts counting. If the timer (for example, 5 minutes) finishes timing, and the count value of the counter has reached a preset message pair number threshold (for example, 6), it is determined that "the preset session state request rule is satisfied", a process of acquiring the session state of the user equipment is triggered, and meanwhile, the timer and the counter are cleared. And if the count value of the counter still does not reach the threshold of the number of the preset messages when the timer finishes timing, clearing the timer and the counter. And restarting the timer and the counter when a new message pair is received next time.
In one embodiment of the present invention, the predetermined detection rule may be detected every time the predetermined time point is reached. Based on this, according to the preset detection rule, detecting the number of the received message pairs may include: and detecting whether the number of the received message pairs in the time period from the last preset time point to the current preset time point is not less than a second preset message pair number threshold or not every time the preset time point is reached, and if the number of the message pairs is detected to be not less than the second preset message pair number threshold, indicating that the detection result meets the preset session state request rule.
In an embodiment of the present invention, the second preset message pair number thresholds corresponding to the preset time points may be the same.
In an embodiment of the present invention, the second preset message pair number threshold corresponding to each preset time point may be set differently based on the consideration that the user has fewer calls at night (rest time) and in the daytime (e.g., during work).
For example, the preset time points are 8:00, 18:00, 20:00, 21:00 and 22:00, the threshold value of the number of second preset message pairs corresponding to 8:00 is 100, the threshold value of the number of second preset message pairs corresponding to 18:00 is 300, the threshold value of the number of second preset message pairs corresponding to 20:00 is 90, the threshold value of the number of second preset message pairs corresponding to 21:00 is 60, and the threshold value of the number of second preset message pairs corresponding to 22:00 is 60.
And 8:00, detecting whether the number of the received message pairs in ten hours from 22:00 of the previous day to 8:00 of the current day is not less than 100, and if the detected number of the message pairs is not less than 100, acquiring the session state of the user equipment.
At 18:00, detecting whether the number of received message pairs in ten hours from 8:00 to 18:00 is not less than 300, and if the number of detected message pairs is not less than 300, acquiring the session state of the user equipment.
At 20:00, detecting whether the number of received message pairs in two hours from 18:00 to 28:00 is not less than 90, and if the detected number of message pairs is not less than 90, acquiring the session state of the user equipment.
21:00, detecting whether the number of received message pairs in one hour from 20:00 to 21:00 is not less than 60, and if the detected number of message pairs is not less than 60, acquiring the session state of the user equipment.
At 22:00, detecting whether the number of received message pairs in one hour from 21:00 to 22:00 is not less than 60, and if the detected number of message pairs is not less than 60, acquiring the session state of the user equipment.
It is understood that, every time the preset time point is reached, whether the number of the received message pairs in the time period from the last preset time point to the current preset time point is not less than the second preset message pair number threshold value is detected, and a counter may be set to count the number of the message pairs. And when the preset time point is reached, resetting the counter to zero and counting again.
After the session state of the user equipment is acquired, if the session state of the user equipment is a no-session state, it is determined that a situation of 'voice dedicated bearer drop death' occurs currently, and at this time, a voice dedicated bearer deactivation request is sent to an eNodeB and a voice dedicated bearer deletion request is sent to an SAE-GW to delete the voice dedicated bearer. And then the special voice bearer is released, so that the phenomenon of 'the special voice bearer is dead due to falling' can be avoided, the SRVCC performance can be improved, the occupation of wireless resources of a GERAN network is reduced, and the service is not influenced.
In an embodiment of the present invention, acquiring the session state of the user equipment may include: sending an acquisition request for acquiring a session state of user equipment to an application Server (SCC AS) in a Home network through a Home Subscriber Server (HSS); and receiving the SCC AS response acquisition request, and feeding back the session state of the user equipment through the HSS.
It can be understood that the acquisition request carries identification information of the user equipment.
In one embodiment of the present invention, the acquisition request may be sent to the HSS over the S6a interface, and the HSS forwards the acquisition request to the SCC AS over the Sh interface.
In an embodiment of the present invention, if the session state of the ue is a non-session-free state, a normal SRVCC procedure is performed to perform a network handover.
Fig. 2 shows a signaling diagram of a voice specific bearer process provided by an embodiment of the present invention.
The eNodeB sends handover required and handover cancel (1a, handover required and 1b, handover cancel) to the MME.
The MME detects whether the number of the message pairs including handover required and handover cancel reaches a preset message pair number threshold (2, detects whether the number reaches the preset threshold).
If the MME detects that the number of the message pairs reaches a preset message pair number threshold, sending an acquisition request (3a, a session state request) for acquiring the session state of the user equipment to the HSS, forwarding the acquisition request to an SCC AS (3b, a session state request) by the HSS, responding the acquisition request by the SCC AS, and feeding back the session state (3c, a session state response) of the user equipment to the HSS; and the HSS forwards the session state of the user equipment fed back by the SCC AS to the MME (3d, session state response).
If the session state of the user equipment is a no-session state, the MME sends a voice dedicated bearer deactivation request (4a, a request for deactivating the dedicated bearer) to the eNodeB and sends a voice dedicated bearer deletion request (4b, a request for deleting the bearer) to the SAE-GW.
The eNodeB receives the voice dedicated bearer deactivation request, and performs deactivation processing (deactivation processing) on the voice dedicated bearer.
The SAE-GW receives the voice dedicated bearer deletion request and deletes the voice dedicated bearer (6, delete bearer).
And if the session state of the user equipment is a non-session-free state, executing a normal SRVCC process.
The method for processing the special voice bearer in the embodiment of the invention can release the special voice bearer by deleting the special voice bearer, thereby avoiding the phenomenon of' the special voice bearer is dead, improving the SRVCC performance, reducing the occupation of radio resources of a GERAN network and not influencing the service.
