Detailed Description
As known from the background art, the quality of the call service of the VoWiFi in the prior art is not guaranteed.
Generally, when the bandwidth utilization rate of a user is low, no obvious influence is caused on the VoWiFi call quality of the user, but with the occupation of the bandwidth, when the network bandwidth utilization reaches a certain amount, and the delay of the VoWiFi reaches more than 200ms, the user can obviously feel the problem of the call quality. The inventor finds, through research, that in a VoWiFi connection mode (S2b interface) applied to an untrusted WiFi network and a core network, an 802.11e WMM scheme is used between a User Equipment (UE) and a wireless access Point to ensure service quality, a dedicated bearer network is provided between an evolved Packet Data Gateway (ePDG) and a signaling Gateway (SGW, Signal Gate Way) and a public Data network Gateway (PGW, PDN Gate Way), and the core network has a Differential Service Code Point (DSCP) to ensure service quality, but there is no guarantee of service quality between the UE and the Packet Data evolved Gateway, so that a common home broadband user may seriously affect the call quality of the VoWiFi when using high-speed downloading, and the call quality may not meet the basic VoIP quality requirement.
Based on the above research, the embodiment of the present invention provides a network connection method, which provides support for the service quality of the VoWiFi by the access network, so that the VoWiFi has service quality guarantee in the end-to-end complete link process. Under the condition of not limiting the user, the access equipment only uses the VoWiFi to reserve resources for the VoWiFi service in the attaching (attach) process, so that the conversation quality of the user cannot be influenced no matter whether the bandwidth utilization rate of the user reaches 100 percent or not.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
It should be noted that these drawings are provided to facilitate understanding of the embodiments of the present invention and should not be construed as unduly limiting the invention.
First, referring to fig. 1, fig. 1 shows a network connection block diagram of VoWiFi according to an embodiment of the present invention. The user equipment 10 accesses a public wireless lan 20 and then accesses an Evolved Packet Core (EPC) 30 through an Evolved Packet data gateway ePDG 500. An Internet Protocol Security (IPSec) tunnel may be used between the user equipment 10 and the evolved packet data gateway 500 to carry data, so that a network element of an untrusted network cannot sense data transmission, thereby ensuring Security of data transmission, and at this time, a Subscriber Identity Module (SIM) of the user equipment 10 is used for authentication, so that an intruder cannot access the evolved packet data gateway 500 and the core network 30. Further, the evolved packet data gateway 500 is handed over to the operator IP multimedia subsystem 40 through the public data network gateway PGW.
Fig. 2 is a flowchart illustrating a network connection method according to an embodiment of the present invention, for providing quality of service support for VoWiFi by an access network.
First, step S101 is executed, and the user equipment UE10 sends a network connection request to the evolved packet data gateway ePDG500 to the network side equipment.
In this embodiment, the network side device may be a Modem200, and the user equipment UE10 may connect to the Modem200 through a wireless network access point AP. When the user equipment UE10 discovers the wireless network access point AP, it can switch from the LTE network to the WiFi network to obtain better connection status and lower tariff. The WiFi network may be a WiFi network of a home, a WiFi network deployed by a business or an operator. The embodiment of the invention does not limit the networking of the WiFi network, and only needs to provide a basic IP bearing function. In the embodiment of the present invention, the UE10 supports IPSec and Internet key exchange (IKE, Internet key exchange) authentication, and the UE10 initiates an IKE process to the evolved packet data gateway ePDG500 to request to establish a network connection. Generally, the establishment of the IKE tunnel includes negotiating an encryption algorithm, exchanging a time random number, completing a key exchange algorithm exchange, and establishing an IKE connection. In a specific embodiment, the network connection is used for transmitting voice information, and the network connection is based on IPSec and IKEv2 protocols.
When the network side equipment receives a network connection request sent by user equipment UE10 to an evolved packet data gateway ePDG500, the bandwidth resource reservation request is initiated. In this embodiment, the Modem200 receives the network connection request and initiates a bandwidth resource reservation request. The bandwidth resource reservation request may be based on a Common Open Policy Service (COPS) or other protocol. The COPS protocol is an application layer protocol using a query response mode, can be used for exchanging policy information between a policy server and a client, and is also commonly used for performing policy control through a resource reservation protocol signaling message. The communication model defined by the COPS protocol includes two entities: policy Decision Point (PDP) and Policy Enforcement Point (PEP).
Specifically, in this embodiment, the Modem200 executes step S201 to send a bandwidth resource reservation request to the policy decision point PDP 300. After receiving the bandwidth resource reservation request, the policy decision point PDP300 performs steps S301 and S302, that is, sends a bandwidth resource reservation request to the policy enforcement point PEP400 and the evolved packet data gateway ePDG500, respectively. When the policy enforcement point PEP400 successfully reserves resources, step S401 is executed, and a bandwidth resource request acknowledgement message is sent to the policy decision point PDP 300; after the resource reservation is successfully performed, the evolved packet data gateway ePDG500 performs step S501, and also sends a bandwidth resource request acknowledgement message to the policy decision point PDP 300. The policy decision point PDP300 receives the feedback information of the policy enforcement point PEP400 and the evolved packet data gateway ePDG500, that is, after receiving the resource reservation request acknowledgements from the policy enforcement point PEP400 and the evolved packet data gateway ePDG500, respectively, then performs step S303, and sends the resource reservation result, that is, the resource reservation request acknowledgement message, to the Modem 200. After receiving the resource reservation request success confirmation message from the policy decision point PDP300, the Modem200 continues the IKE process, and executes step S202 to send a network connection request to the evolved packet data gateway ePDG 500. The ePDG500 then performs step S502 to complete the operations of authorization, IKE tunnel establishment, address configuration, and the like for the UE 10.
In the above embodiment, the steps only need to be performed between the access provider and the evolved packet data gateway ePDG500, and the user equipment UE10 does not need to make any changes. Since the access provider has the implementation scheme of own resource reservation, only the address of the ePDG500 needs to be transmitted to the Modem, and thus the existing protocol is slightly changed.
Further, fig. 3 shows a flowchart of a network connection method according to another embodiment of the present invention. The difference compared to the previous embodiment is that in this embodiment, the bandwidth resource reservation request is initiated by an evolved packet data gateway ePDG.
Specifically, when the user equipment UE10 discovers the wireless network access point AP and performs handover, the user equipment UE10 may initiate an IKE procedure to the ePDG, and execute step S211, and send a network connection request to the evolved packet data gateway ePDG500 to the network side device. When the Modem200 receives a network connection request sent by the user equipment UE10 to the evolved packet data gateway ePDG500, the Modem200 executes step S211 to send the network connection request to the evolved packet data gateway ePDG 500. After receiving the network connection request, the evolved packet data gateway ePDG500 performs step S511, initiates a bandwidth resource reservation request, and sends the bandwidth resource reservation request to the policy decision point PDP 300. The policy decision point PDP300 then executes step S311, and sends a bandwidth resource reservation request to the policy enforcement point PEP 400. The policy enforcement point PEP400 then performs step S411 to send a bandwidth resource reservation request to the Modem 200. After the resource reservation is successfully performed, the Modem200 executes step S212 to send a bandwidth resource request confirmation message to the policy enforcement point PEP 400. Next, the policy enforcement point PEP400 executes step S412 to send a bandwidth resource request acknowledgement message to the policy decision point PDP 300. The policy decision point PDP300 executes step S312 to send a bandwidth resource result, i.e. a bandwidth resource request acknowledgement message, to the evolved packet data gateway ePDG 500. The ePDG500 then performs step S512 to complete the operations of authorization, IKE tunnel establishment, address configuration, and the like for the UE 10.
In the above embodiment, the evolved packet data gateway ePDG500 initiates the resource reservation request, and the evolved packet data gateway ePDG500 side needs to be modified, the Modem200 does not need to be modified, and the access network only needs to multiplex the existing resource reservation scheme.
It should be noted that, in some other embodiments, the user equipment UE10 may also initiate a bandwidth resource reservation request, and those skilled in the art should understand the relevant operations based on the description of the foregoing embodiments, and details are not described here.
In the above embodiment, the bandwidth resource reservation may be before or after IKE or authorization, but certainly before data link handover, the bandwidth resource is reserved by the network side device and the evolved packet data gateway ePDG, and a subsequent IPSec tunnel is transmitted between the Modem and the access device through a channel of the reserved bandwidth resource to reach the evolved packet data gateway ePDG500, so that even if a user occupies a large amount of bandwidth, the call quality is not affected.
In addition, the embodiment of the invention also provides a processing method when the resource reservation request fails. In the following, a description is given by taking an example of a failure of a resource reservation request initiated by an evolved packet data gateway ePDG corresponding to fig. 3, and similar processing may be performed in other cases, which is not listed here.
Specifically, referring to fig. 4, after the policy enforcement point PEP400 performs step S411 to send a bandwidth resource reservation request to the Modem200, if the bandwidth resource reservation request is rejected, the Modem200 performs step S213 to send a feedback message of the rejection of the bandwidth resource reservation request to the policy enforcement point PEP 400. Next, the policy enforcement point PEP400 executes step S413 to send a bandwidth resource request rejection message to the policy decision point PDP 300. The policy decision point PDP300 executes step S313 to send a bandwidth resource result to the evolved packet data gateway ePDG500, that is, the bandwidth resource request is rejected. The ePDG500 then performs step S513, and the IKE authorization tunnel establishment for the UE10 fails.
The above embodiments provide a processing method when the bandwidth resource reservation fails, that is, the handover should be interrupted or the user should be notified of the current quality of service state, and the resource reservation may be retried in the subsequent steps to perform the handover.
In addition, the embodiment of the invention also provides a method for releasing the reserved bandwidth resources in the absence of flow.
Specifically, referring to fig. 4, when the policy enforcement point PEP400 detects that the currently reserved bandwidth resource is in a no-traffic state and is overtime, the policy enforcement point PEP400 performs step S421 and step S422, and the policy decision point PDP300 and the Modem200 respectively send a bandwidth resource release request message. The policy decision point PDP300 then executes step S321 to send a bandwidth resource release request message to the evolved packet data gateway ePDG 500. After the corresponding operation is completed by the evolved packet data gateway ePDG500, step S521 is executed, and a bandwidth resource release confirmation message is sent to the policy decision point PDP 300. The policy decision point PDP300 then executes step S322 to send a bandwidth resource release confirmation message to the policy enforcement point PEP 400. After completing the corresponding operation, the Modem200 executes step S221, and sends a bandwidth resource release confirmation message to the policy decision point PEP 300. Thereby completing the release of the reserved bandwidth resources and recovering the reserved resources in time.
Correspondingly, the embodiment of the invention also provides a network connection device, which is used for executing the network connection method. Specifically, referring to fig. 6, the network connection apparatus includes a receiving unit 610, a resource reservation unit 620, a transmitting unit 630, and a connection unit 640.
The receiving unit 610 is configured to receive a network connection request sent by a user equipment UE to an evolved packet data gateway ePDG; the resource reservation unit 620 is configured to reserve bandwidth resources at the network side device and the evolved packet data gateway ePDG; the sending unit 630 is configured to send the connection request to the evolved packet data gateway ePDG; the establishing unit is configured to determine whether to establish a network connection between the UE and the ePDG based on whether reservation of bandwidth resources between the network side device and the ePDG is successful.
