On the basis not changing existing network framework, embodiments provide a kind of circuit domain dropping method for establishing voice call, the method is applied to wireless network control apparatus, and this wireless network control apparatus both can be the RNC in 3G network, can also be the BSC in 2G network.
As shown in Figure 1, the method comprises:
S101: receive the connection request message that subscriber equipment sends, this connection request message is used for service request and falls the annexation set up to 2G/3G network between subscriber equipment and 2G/3G network after rise.
Based under redirected falling scene, after CSFB business initiated in the lte networks by subscriber equipment, LTE network access side cuts off and accesses side with LTE network by sending RRC Connection Release (RRC Connection Release) message to subscriber equipment and be connected, and carries redirected frequency point information equipment for indicating user within the message and corresponding 2G/3G network side connects; Subscriber equipment passes through after receiving this connection release message to send connection establishment request message to the 2G/3G network insertion side after falling, connects with 2G/3G network, for the connection setup of subscriber equipment in subsequent process and 2G/3G network is basic.As when falling is to the 3G network of WCDMA, subscriber equipment is initiated WCDMA RRC Connection Request message request and WCDMA network insertion side to network access equipment RNC and is connected.
In prior art, under the voice and packet data concurrent service scene that not only there is data service but also there is speech business, after subscriber equipment and 2G/3G network connect, for 3G network, RNC needs respectively speech business and data service to be carried out to the processing procedures such as the distribution of authentication ciphering signaling, location area updating (speech business) or Routing Area Update (data service) and RAB (Radio Access Bear, RAB) resource; In this processing procedure, the order that RNC arrives according to signaling processes successively, when preferentially receiving the RAB resource allocation request of core network packet-domain equipment, RNC carries out the distribution of packet domain RAB, during this period, if when receiving the RAB resource allocation request of core net circuit domain equipment, after then needing to wait for being assigned of packet domain RAB, just can carry out the distribution of circuit domain RAB, thus audio call setup delay is comparatively large, affects Consumer's Experience.
In order to reduce the time delay that audio call is set up, first the present embodiment adds the identifying of voice and packet data concurrent service, and as described in following step S102, then on the basis of voice and packet data concurrent service identification, the process of delayed data traffic signaling, as described in following step S103.
S102: according to connection request message, determines whether subscriber equipment exists voice and packet data concurrent service demand, and this exists voice and packet data concurrent service demand for both there is speech business demand, there is data traffic requirement again.
Except CSFB speech business, also may there is data service in the type of service that current user equipment exists simultaneously.In order to determine the type of service that subscriber equipment is current, wireless network control apparatus receive subscriber equipment send connection request message after, the business demand current according to the cause value determination subscriber equipment carried in this connection request message.Due to the present invention mainly for be the problem of the time delay of CSFB speech business call setup under voice and packet data concurrent service scene, thus main foothold is the identification of voice and packet data concurrent service, then in a kind of implementation of this method, if this connection request message carries voice and packet data concurrent service mark, then determine that subscriber equipment exists voice and packet data concurrent service demand.Only can determine that current user equipment exists CSFB speech business demand with network insertion side apparatus in prior art according to the cause value in connection request message, and cannot determine whether that also there is data traffic requirement compares simultaneously, the present embodiment is identified by voice and packet data concurrent service and indicates current business demand to be voice and packet data concurrent service demand, when connecting the cause value carried in access request and being voice and packet data concurrent service mark, determine that subscriber equipment had both existed speech business demand, there is data traffic requirement again; Otherwise, can determine that subscriber equipment only exists speech business demand.Preferably, this voice and packet data concurrent service mark can be " CSFB with PS ".
S103: if subscriber equipment exists voice and packet data concurrent service demand, then the process of the signaling of delayed data business.
If subscriber equipment does not exist voice and packet data concurrent service demand, then carry out according to normal flow.
Wireless network control apparatus is as intermediary, on the basis identifying voice and packet data concurrent service type, Signalling exchange between subscriber equipment and core network packet-domain equipment all needs the forwarding by wireless network control apparatus, thus by signaling delay process that the data service that will receive is relevant, CSFB speech business is carried out to the mode of normal process, reach the effect of priority treatment CSFB speech business.
It should be noted that, in the embodiment of the present invention there is voice and packet data concurrent service demand for representing that subscriber equipment has speech business demand and data traffic requirement in the subscriber equipment of indication, and this speech business and data service are in the process carrying out setting up, namely speech business and data service have not yet been set up; In addition the technical problem solved due to this programme reduces the time delay of audio call foundation, thus need start to perform before audio call has been set up to the delay disposal of data business signaling in the present embodiment.
In a kind of implementation of this step, if subscriber equipment exists voice and packet data concurrent service, then postpone to core network packet-domain device forwards first message, this first message is the message for setting up data service that subscriber equipment sends to core network packet-domain equipment.
In 3G network, this first message can be Routing Area Update (Route Area Update is called for short RAU) request message, power of being also exemplary response (Authentication Response) message.
In the another kind of implementation of this method, postpone to forward the second message to subscriber equipment, this second message is the message for setting up data service that core network packet-domain equipment sends to subscriber equipment.
In 3G network, this second message is exemplary and is weighed request (Authentication Request) message, also can be that the RAB of packet domain distributes request (RAB Assignment Request) message.
The order that signaling due to data service and speech business arrives RNC cannot be determined, thus, before audio call is set up, the second message for the treatment of data service sent by the first message for the treatment of data service or core network packet-domain equipment postponing any subscriber equipment transmission all can reduce the time delay that audio call is set up.
In the repeating process of delay first message, also need to send a notification message to subscriber equipment, be used to indicate the first message receiving subscriber equipment and send, in the listening period preset, do not receive the response message corresponding with the first message in order to avoid subscriber equipment simultaneously and think that the first message sends unsuccessfully, this notification message is also used to indicate the default listening period of subscriber equipment amendment to extend listening period.
In like manner, in the repeating process in delay second message, also need to the instruction of core network packet-domain equipment dispatch order, be used to indicate the second message receiving core network packet-domain equipment and send, in the listening period preset, do not receive the response message corresponding with the second message in order to avoid core network packet-domain equipment simultaneously and think that the second message sends unsuccessfully, this notification message is also used to indicate the default listening period of core network packet-domain apparatus modifications to extend listening period.
The CSFB method for establishing voice call that the embodiment of the present invention provides, compared with the business of Stochastic choice priority treatment in prior art, first add and determine whether subscriber equipment exists the identifying of voice and packet data concurrent service demand, exist on the basis of voice and packet data concurrent service demand recognizing subscriber equipment, the process of the signaling of delayed data business, normal process is carried out to speech business, can under any circumstance all priority treatment CSFB speech businesses, reduce the time delay of CSFB speech business call setup.Through testing authentication, relative and prior art, CSFB method for establishing voice call provided by the invention effectively can reduce CSFB audio call time delay 500ms-1.5s.
