Description
Technical field
The present invention relates to mobile communication technology, relate in particular to a kind of method that packet switch domain service interrupts that in route district and location area updating process, reduces.
Background technology
Two sending modes (Dual Transfer Mode, DTM) technology is that a kind of voice of can realizing simultaneously on global system for mobile communications (GSM)/enhanced data rates for gsm evolution technology (EDGE) network connect the technology that is connected with data, being characterized in can (Mobile Station MS) provides circuit domain (CS) professional and packet domain (PS) business service simultaneously to travelling carriage.
For the travelling carriage that is under the DTM pattern, because the system message of circuit domain business and packet switch domain service all is to receive in circuit domain, therefore, the ifs circuit territory connects release, and packet domain connects also and must discharge so.If current group territory business does not also finish, then travelling carriage needs read system message again, rebuilds packet domain and connects.Wherein, packet domain connect be discharged into the packet domain connection reconstruction during this period of time in, will inevitably cause the interruption of packet switch domain service.The DTM circuit domain discharges (DTM CS release) and proposes for the interruption that reduces packet switch domain service, promptly when discharging the circuit domain connection, network side is to travelling carriage transmitting system message, and after travelling carriage has obtained its required system message, the release circuit domain connects, and keeps packet domain to connect.So just can guarantee that circuit domain connects the continuity of packet switch domain service when discharging, thereby guarantee the service quality (QoS) of packet switch domain service.
In the GSM/EDGE system, to the paging of travelling carriage circuit domain business is to realize by the paging to all sub-districts in the travelling carriage position district (LA), is to realize by the paging to all sub-districts in the route district, travelling carriage place (RA) to the paging of travelling carriage packet switch domain service.The lane place is the notion of circuit domain, each lane place all uses a unique Location Area Identification (LAI) to represent, the route district is the notion of packet domain, each route district all uses a unique Routing Area Identifier (RAI) to represent, a lane place may comprise a plurality of routes district, and a route district comprises a plurality of sub-districts.When travelling carriage moves to another lane place by a lane place, must notify core net, make core net know the lane place at the current place of travelling carriage, promptly carry out location area updating.When travelling carriage moves to another route district by a route district, also to notify core net, make core net know the route district at the current place of travelling carriage, promptly carry out Routing Area Update.When being in travelling carriage under the DTM pattern and moving to new lane place, lane place and route district all can change, and wherein, circuit domain connects to switch by CS and keeps, and does not have PS to switch if packet domain connects, and can't be maintained.
Referring to shown in Figure 1, in the existing protocol,, when travelling carriage is in the DTM pattern and is moved to new lane place, continue the holding circuit territory and connect if travelling carriage and network are all supported DTM CS release, the more new technological process of its route district and lane place mainly may further comprise the steps:
Step 101: travelling carriage and service general grouping service wireless (GPRS) support node (SGSN) carry out Routing Area Update.
Step 102: connect in the dispose procedure in circuit domain, travelling carriage is to the up transmitting system message request of network side, as system message state (PACKET SI STATUS) or grouping system message status (PACKET PSI STATUS) message, and in the system message request, carry the indication of forbidding carrying out DTM CSrelease function.
Why connecting the execution of forbidding DTM CS release function in the dispose procedure in circuit domain, is because this fashion is not introduced DTM to be switched, after the Routing Area Update, packet switch domain service can't be maintained, therefore, this moment is if carry out DTM CS release function, obviously without any meaning.
Step 103: after circuit domain connected release, travelling carriage was got back to idle condition, carries out location area updating according to network operation mode.
If network operation mode I then carries out the joint route area/location and upgrades; If network operation mode II or III then only carry out location area updating.Wherein, Routing Area Update carries out between MS and SGSN, and location area updating carries out between MS and mobile switching centre (MSC).Travelling carriage could be initiated location area updating after circuit domain connects release.
As seen, existing protocol has discharged the circuit domain connection simultaneously and has been connected with packet domain in the renewal process of route district and lane place.But, along with switching, DTM promptly carries out the introducing that CS switches and PS switches simultaneously, and in the renewal process of route district and lane place, circuit domain connects and is connected and can be maintained with packet domain.And if this moment when circuit domain business finishes, discharge and also to have discharged the packet domain connection when circuit domain connects, so,, then will cause the interruption of packet switch domain service if current group territory business does not finish, thereby the QoS quality of reduction packet switch domain service.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of method that packet switch domain service interrupts that reduces, the packet switch domain service that reduces in route district and the location area updating process interrupts.
For achieving the above object, technical scheme provided by the invention is as follows:
For the travelling carriage that is under the DTM, in route district and location area updating process, carry out DTMCS release function, keep packet domain to connect.
This scheme specifically may further comprise the steps:
A, in route district and location area updating process, when discharging circuit domain and connecting, travelling carriage sends to network side and does not carry the system message request of forbidding carrying out the indication of DTM CS release function;
After B, network side are received the system message request,, and after travelling carriage has obtained its required system message, discharge circuit domain and connect, keep packet domain to connect to travelling carriage transmitting system message.
Wherein, described not carrying forbids that carrying out DTM CS release function is designated as: indication in the system message request is forbidden carrying out ccontaining sky in the indicating bit of DTM CS release function;
Perhaps be: remove and indicate the indicating bit of forbidding carrying out DTM CS release function in the system message request.
This shows, the present invention is in the renewal process of route district and lane place, by carrying out DTM CSrelease function, kept the packet domain connection, thereby the packet switch domain service that has reduced in route district and the location area updating process interrupts, guarantee the continuity of packet switch domain service, improved the QoS quality of packet switch domain service.
