Or multiple eNB2 (usually multiple), EPC2 include MME2 and other equipments of the core network.In addition, assuming to build with UE1 in Fig. 1
Vertical call is UE2 to lateral terminal, it is assumed that UE2 is caller, UE1 is called, if UE2 wants the card 1 of calling UE1, UE2 needs
Pass through network (EPC1 and E-UTRAN1) call card 1 of the first operator；Similar, if UE2 wants the card 2 of calling UE1,
UE2 needs network (EPC2 and E-UTRAN2) call card 1 by the second operator.Likewise, assume UE2 be called, UE1 is
Caller, UE1 issues the difference of smart card used in call request, then the operation that calling procedure and communication process are passed through
Quotient's network is not also identical.
If UE1 is communicated using card 1 by the network and UE2 of the first operator, UE1 and E-UTRAN1 (be could also say that
ENB1 it needs to establish RRC (Radio Resource Control, unlimited resources control) connection between), be needed between eNB1 and EPC1
The connection of S1 interface is established, specifically, needing to connect by S1-MME interface between eNB1 and MME1, needs to pass through between eNB1 and SGW
S1-U interface connection.Likewise, also needing to establish RRC connection if UE1 is communicated using card 2 by the network and UE2 of the second operator
It is connected with S1 interface, details are not described herein.
Based on above system framework, the embodiment of the present application provides a kind of side of voice communication based on the switching of terminal double card
Method flow chart, this method are that interactive operation is completed between terminal, access network equipment and equipment of the core network.With reference to shown in Fig. 2
Based on terminal double card switching voice communication method flow diagram, this method comprises:
S101, the first smart card installed at the terminal voice service after, the equipment of the core network of the first operator
Or access network equipment starts timer.
If UE1 passes through card 1 and other terminals carry out voice communication (carrying out voice service), need using the first operator
ENB1 and EPC1 Internet resources, i.e. between UE1 and eNB1 establish have RRC connection, between eNB1 and MME1 establish have S1-
The connection of MME interface, establishing between eNB1 and SGW has S1-U interface connection.
Exemplary, at the end of the voice service, eNB1 can star first timer and second timer.First timing
Device is towards the RRC Connection Release timer eated dishes without rice or wine, i.e., when first timer expires (time-out of first timer), if eNB1
After UE1 is still not detected from starting first timer having business, then RRC Connection Release signaling (RRC is initiated to UE1
Connection Release), i.e. eNB1 eats dishes without rice or wine to discharge to UE1 initiation, to discharge RRC connection.Certainly, first timer not
When expiring, eNB1 keep and UE1 connection, if so as within the time of first timer UE1 need to carry out business transmission, be not necessarily to
Connection is re-established, signaling process is reduced.Second timer is the timer towards S1 mouthfuls of Connection Releases, i.e. second timer arrives
When the phase, if eNB1 is still not detected after UE1 has business from starting second timer, eNB1 sends the UE or more to MME1
Text release request (UE CONTEXT RELEASE REQUEST), to connect to the S1-MME1 mouth logic of request MME1 release UE1
It connects, MME1 discharges UE1 context, and sends UE context release command (UE CONTEXT RELEASE to eNB1
COMMAND), so that eNB1 discharges UE1 context, meanwhile, MME1 sends UE context to SGW and releases the control instruction, with request
SGW discharges the S1-U mouth logical connection of UE1, and SGW discharges UE1 context, and sends UE context release command (UE to eNB1
CONTEXT RELEASE COMMAND) so that eNB1 discharges UE1 context；Wherein, UE1 context may include: that data pass
Defeated state, authentication information and mobility information.Likewise, eNB1 is kept and MME1 and SGW when second timer is not yet due
Connection, if so as within the time of second timer UE1 need to carry out business transmission, without re-establishing connection, reduce and believe
Enable process.
Again exemplary, at the end of the voice service, eNB1 can star first timer, the second timing of MME1 starting
Device, wherein the explanation about first timer can refer to above-mentioned example.Second timer is to determine towards S1 mouthfuls of Connection Releases
When device, i.e., when second timer expires, if MME1 is still not detected after UE1 has business from starting second timer, MME1
UE1 context is discharged, and sends the release command of UE context (UE CONTEXT RELEASE COMMAND) to eNB1, so that
ENB1 discharges UE1 context, meanwhile, MME1 sends UE context to SGW and releases the control instruction, to request SGW release UE1's
S1-U mouthfuls of logical connections, SGW discharges UE1 context, and sends UE context release command (UE CONTEXT to eNB1
RELEASE COMMAND) so that eNB1 discharges UE1 context；Wherein, UE1 context may include: data transmission state, mirror
Weigh information and mobility information.
In general, timing is longer for second timer is compared with first timer, that has occurred as soon as RRC connection
Release, but the period that S1 mouthfuls of logical connections not yet discharge.During this period of time, in fact it could happen that following situations.
(1) during this period of time, the card 2 of UE1 does not carry out the network that voice service hypothesis UE2 passes through the first operator
Call the card 1 of UE1, voice call request is transmitted to eNB1 by EPC1, eNB1 can the card 1 to UE1 page, if the card 1 of UE1
Response paging, eNB1 stops first timer and second timer, and responds the calling；Alternatively, eNB1 stops first timer,
And the calling is responded, so that MME1 stops second timer；Hereafter, the network of the first operator will be built for the card 1 and UE2 of UE1
Vertical end-to-end speech connection, into voice communication state until end of conversation.(2) during this period of time, the card 1 of UE1 is not opened
Open up voice service.Assuming that card 2 of the UE2 by the calling network UE1 of the second operator.The voice call request is transmitted to by EPC2
ENB2, eNB2 can the card 2 to UE1 page, when UE1 listens to the paging from eNB2 in monitoring cycle, will response should
Paging, UE1 will be switched on card 2 and work, and the network of the second operator will be established end-to-end speech for the card 2 and UE2 of UE1 and be connected
It connects, into voice communication state until end of conversation.
Situation is planted for (2), the network that UE1 leaves the first operator enters the network of the second operator, according to existing
Standard agreement, the network side equipment (such as eNB1 or MME1) of the first operator only having service request paging less than UE1,
Or can't detect UE1 for a long time in the case where net, it just can determine whether UE1 off-grid, discharge in eNB1 and EPC1 (specifically MME1)
The context of middle UE1.Before this, the case where UE1 off-grid being not aware that due to the network side equipment of the first operator, UE1's
Context is also not released, and can occupy storage resource, and when the card 1 of UE1 is called, MME1 still can be by call request
It is given to eNB1, eNB1 can still occupy interface-free resources and initiate to page to the card 1 of UE1, lead to the waste of Internet resources.In order to solve this
One problem can refer to following step S102-S105.
S102, terminal receive called or initiation caller by the second smart card.
Terminal received by the second smart card it is called, i.e., the network side equipment that terminal receives the second operator issue the
One call request, wherein the first call request corresponds to the second smart card.Such case is shown in Fig. 2, EPC2 is received for example
Call request of the UE2 to the card 2 of UE1, and the call request is transmitted to eNB2, eNB2 initiates paging to the card 2 of UE1.
Alternatively, terminal initiates caller by the second smart card, i.e. terminal sends the to the network side equipment of the second operator
Two call requests, wherein the second call request corresponds to the second smart card.In conjunction with system architecture diagram shown in fig. 1, UE1 passes through card 2
The calling for being directed to such as UE2 is initiated to eNB2, which is sent to EPC2 by eNB2, to arrive by Cellular Networks paging
UE2。
S103, terminal send terminal off-network information to the network side equipment of the first operator by the first smart card, accordingly
, the access network equipment of the first operator receives the terminal off-network letter that terminal is sent by the first smart card of installation at the terminal
Breath；Terminal off-network information is for indicating that terminal leaves the network of the first operator.
UE1 determine step S102 occur when, decision be switched to card 2 work, at this time by card 1 to eNB1 transmission terminal from
Net information.Terminal off-network information is used to make in the case where second timer is not out of date the network side equipment of first operator
(eNB1 and MME1) discharges the S1 mouth logical connection of UE1, and terminal off-network information may include terminal off-network reason, further may be used also
To include: the terminal off-network time.
Exemplary, UE1 sends terminal off-network message (UE Departure Message) to eNB1, and message format is as follows:
Message above indicates: terminal off-network information may include a terminal off-network cell (UE Departure), the terminal
Off-network cell may include a terminal off-network reason cell (CauseValue indicates the reason of terminal leaves carrier network) and sky
Remaining position (spare), the value of terminal off-network reason cell is OperatorChangeforVoiceCall in the present embodiment, is come
It indicates to change core net (or operator) due to voice service.In addition, terminal off-network reason cell can also have other values (can be with
It is one or more), therefore it is subsequent expansible to ensure to reserve certain space (Bit, bit).Above-mentioned spare bits can be with
The information such as terminal off-network time are written.
S104, first operator's access network equipment set the core net that the terminal off-network information is sent to the first operator
Standby, the equipment of the core network of the first operator receives and stores the terminal off-network information that the access network equipment of the first operator is sent.
Exemplary, eNB1 is after being apprised of UE1 since switching needs off-network between voice service progress operator, Ke Yixiang
EPC1 (such as can be MME1) sends terminal contexts release request (UE CONTEXT RELEASE REQUEST) message, should
Terminal off-network information can be increased in terminal contexts release request message.Wherein, terminal contexts release request message includes
Content can refer to following table 1.
Table 1
S105, the first operator equipment of the core network receive terminal off-network information after, if the S1 mouth logical connection of terminal
Not discharging, then the equipment of the core network of the first operator is according to terminal off-network information, discharge the S1 mouth logical connection of terminal, and to
The access network equipment of first operator sends the order for discharging the S1 mouth logical connection of terminal；Correspondingly, the first operator
Access network equipment receive and execute that the equipment of the core network of first operator sends for discharging the S1 mouth logic of terminal
The order of connection.
Exemplary, MME1 is in the undue situation of second timer, if wrapping in the release request of received terminal contexts
Terminal off-network information containing UE1 then discharges the S1-MME1 mouth logical connection of UE1, and the terminal contexts of UE1 are sent to eNB1
Release command (UE CONTEXT RELEASE COMMAND)；After eNB1 receives the terminal contexts release command of UE1, release
The S1 mouth logical connection of UE1, meanwhile, MME1 sends UE context to SGW and releases the control instruction, to request SGW release UE1's
S1-U mouthfuls of logical connections, SGW discharges UE1 context, and sends UE context release command (UE CONTEXT to eNB1
RELEASE COMMAND) so that eNB1 discharges UE1 context.In addition, can also be sent to MME1 after the completion of eNB1 release
(UE CONTEXT RELEASE COMPLETE) message is completed in the terminal contexts release of UE1.
S106, terminal establish voice communication connection by the network side equipment of the second smart card and the second operator.
