In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Fig. 1 illustrates a flow diagram of some embodiments of a method of processing communication traffic of the present disclosure.
As shown in fig. 1, the method includes: step 110, acquiring first LTE access information; step 120, acquiring second LTE access information; step 130, determining position information; step 140, generating a second VoWiFi service request; step 150, sending a second VoWiFi service request.
In step 110, first LTE access information of the terminal cached at the terminal side is obtained from a first VoWiFi service request initiated by the terminal and related to the location information.
For example, a P-CSCF (Proxy Call Session Control Function) network element or a BAC (Border Access Controller) in the IMS network receives a first VoWiFi service request initiated by the terminal.
In some embodiments, the first LTE access information includes a first location identifier and a corresponding first timestamp, and the first location identifier is an LTE cell identifier of the last access cached by the terminal after leaving the LTE network. For example, after leaving the LTE access, the terminal continues to cache the Cell-ID and timestamp of the last LTE access.
In some embodiments, the first VoWiFi service request is an INVITE message, and the PANI header field of the INVITE message includes the first LTE access information. For example, two parameters may be extended in the PANI header field of SIP (Session Initiation Protocol): a last-utran-cell-id-3gpp parameter and a last-utran-cell-id-3gpp-time parameter. The last-utran-Cell-ID-3gpp parameter stores LTE Cell information (for example, Cell-ID of the LTE Cell) that the terminal has accessed last time, and the last-utran-Cell-ID-3gpp-time parameter stores time information (for example, a timestamp mode may be adopted) that the terminal has accessed LTE last time.
In step 120, second LTE access information of the terminal cached by the network side is obtained from the EPC network. The second LTE access information includes a second location identifier and a corresponding second timestamp.
In some embodiments, a second location identifier and a corresponding second timestamp are cached in the EPC network, and the second location identifier is an LTE cell identifier cached in the EPC network and accessed by the terminal last time. That is, the network side also caches LTE access information of the terminal. Therefore, the P-CSCF network element or the BAC may obtain the second LTE access information cached at the network side, and compare with the first LTE access information to determine the location information of the terminal.
In some embodiments, the P-CSCF network element or the BAC sends an access information acquisition request (i.e., an acquisition request of LTE access information cached on the network side) to the PCRF network element. And the PCRF network element forwards the access information acquisition request to the EPC network, and the EPC network returns the second LTE access information to the P-CSCF network element or the BAC through the PCRF network element. For example, the P-CSCF network element or the BAC may send the access information acquisition request to the PCRF network element through the Rx interface.
In step 130, the location information of the terminal is determined according to the time information of the first LTE access information and the time information of the second LTE access information.
In some embodiments, in the case that the first timestamp is later than the second timestamp, the first location identity (LTE access information cached at the terminal side) is determined as the location information; and determining the second position identification (the LTE access information cached by the network side) as the position information under the condition that the first time stamp is earlier than the second time stamp.
In step 140, a second VoWiFi service request is generated according to the location information.
In some embodiments, the first LTE access information in the first VoWiFi service request is updated to generate a second VoWiFi service request according to the location information.
In some embodiments, the P-CSCF network element or the BAC updates the PANI header field of the INVITE message as the second VoWiFi service request according to the location information.
In step 150, the second VoWiFi service request is sent to the service-related network element, so that the service-related network element determines the location of the terminal according to the second VoWiFi service request, thereby completing the related processing.
In some embodiments, if the VoWiFi service request is a roaming call request, the service-related network element is an MMTel network element, and the MMTel network element completes the area code of the called number according to the location of the terminal, so as to complete the roaming call request. For example, the P-CSCF network element or the BAC routes the second VoWiFi service request to an S-CSCF (Serving Call Session control function) network element, the S-CSCF network element routes the second VoWiFi service request to the MMTel network element, and the MMTel network element completes the area code of the called number according to the LTE access information in the PANI header field.
In some embodiments, if the VoWiFi service request is an emergency call request, the service-related network element is an E-CSCF network element, and the E-CSCF network element completes the route mapping of the nearby emergency call center according to the location of the terminal. For example, the P-CSCF network element or the BAC routes the second VoWiFi service request to the E-CSCF network element, and the E-CSCF network element completes the routing mapping of the nearby emergency call center according to the LTE access information in the PANI header domain.
Fig. 2 shows a signaling diagram of some embodiments of a method of processing communication traffic of the present disclosure.
As shown in fig. 2, at event 210, the terminal initiates a VoWiFi-free call associated with location information, for example, initiating an emergency call or roaming call. The terminal adds the current WiFi access information and the first LTE access information (Cell-ID information and timestamp of the latest LTE access cached by the terminal side) in the extended parameters in the PANI header field of the INVITE message.
In event 220, the terminal sends an INVITE message to the processing device. The processing means may be, for example, a P-CSCF network element or a BAC.
In event 230, the processing device requests the network side cached LTE cell information that the terminal has accessed last time to the PCRF network element. For example, the processing device and the PCRF network element may interact through AAR signaling or AAA signaling.
In event 240, the PCRF network element forwards the request of the processing device to the EPC network. For example, the PCRF network element and the EPC network may interact through RAR or RAA signaling.
At event 250, the EPC network returns the second LTE access information (Cell-ID and corresponding timestamp cached at the network side) to the PCRF network element. For example, the EPC network and the PCRF network element may interact through CCR or CCA signaling.
In event 260, the PCRF network element forwards the second LTE access information to the processing means. For example, the PCRF network element and the processing device may interact through RAR or RAA signaling.
In event 270, the P-CSCF network element or BAC compares the timestamps of the first LTE access information and the second LTE access information to determine the location information.
In event 280, the PANI header field of the INVITE message is updated according to the location information.
In event 290, the P-CSCF network element or BAC routes the INVITE message to a service-related network element. For example, for an emergency call, the service-related network element is an E-CSCF network element; for the roaming call, the service-related network element is an MMTel network element, and the INVITE message is routed to an S-CSCF network element firstly and then is routed to the MMTel network element by the S-CSCF network element.
In event 292, the service-related network element performs the relevant processing according to the Cell-ID in the PANI header field to complete the VoWiFi call service.
In the embodiment, the LTE cell information that the terminal has accessed last time is added to the VoWiFi service request, so that the service-related network element can acquire the position of the terminal, thereby completing the VoWiFi call service related to the position information and improving the user experience.
