Abstract
According to this scheme, when the conversation priority idle time of the PoC service reaches the preset threshold, the accessing net side shifts the states of all members on this group from CELL_DCH (CD) to CELL_PCH (CP) and releases all wireless resource (WR) between members. In case there is a calling party (CP) to start a conversation, CP pages another member and re-builds WR. All members are shifted back from CP to CD and activate the PoC service. This scheme realizes the always on-line service of PoC without occupying extra resource. It also presets parameters to reduce the PoC delay. This invention keeps the compatibility with the existing technique and is easy to realize.
Description
Technical field
The present invention relates to WCDMA (Wide-band Code Division Multiple Access, WCDMA access system) system, relate in particular to the professional method and system of a kind of control PoC (Push to talk Over Cellular, button is promptly said).
Background technology
Existing UMTS (Universal Mobile Telecommunication System, universal mobile telecommunications system) is the 3-G (Generation Three mobile communication system) that adopts the WCDMA air interface technologies, usually also the UMTS system is called the WCDMA communication system, it provides the various wireless traffics from voice to the wideband data.The WCDMA system has adopted and the similar structure of second generation mobile communication system, comprises UTRAN (UMTSTerrestrial Radio Access Network, wireless access network) and CN (Core Network, core net).Wherein UTRAN is used to handle all and wireless function associated, and CN handles that all voice calls are connected with data in the UMTS system, and the exchange of realization and external network and routing function.CN is from being divided into CS (Circuit Switched Domain, circuit commutative field) and PS (Packet Switched Domain, packet-switched domain) in logic.UTRAN, CN and UE (User Equipment, subscriber equipment) have constituted whole UMTS system together.The CS territory mainly provides the business of traditional circuit exchange mode, as voice and fax etc.; It is the bag interactive service on basis that the PS territory mainly provides with IP (Internet Protocol, Internet protocol), as FTP/HTTP etc.
Along with popularizing and the expansion of IP network of IP communication mode, require communication to develop to the IP direction, to improve the interoperability between the network, reduce the cost of communication simultaneously.Therefore, introduced the notion of IMS (IP Multimedia System, IP Multimedia System) in 3GPP R5/R6 agreement, target is that similar CS is provided in IP network the business in territory, to accomplish the merging of core net to CS and PS territory.IMS provides one to overlap QoS (Quality of Service, quality of service) management method and strategy end to end, by carrying control and professional separating of controlling, make business end to end QoS be guaranteed.The newly-increased cover novel entities of network is handled and is used relevant signaling and user's stream, i.e. IP multimedia CN subsystem, IMS, and all IMS entities are positioned at core net, and the influence of non-IMS network entity is reduced to minimum.3GPP has selected the fixedly Internet multimedia call control protocol SIP of ietf definition as the main agreement of IMS, Session Initiation Protocol semanteme flexibly helps to further develop, and help 3GPP (3rd Generation Partnership Proiect, 3G (Third Generation) Moblie standardization body) network and the fixedly intercommunication between the IP network.The transmission of IMS signaling and user data, the bearer service that the IMS entity utilizes PS and UTRAN to provide.Customer traffic is all thought with IMS signaling and IMS application stream in PS and AN territory, so very little to non-IMS entity influence.As the bearer service that the PS territory provides, PS supports handoff functionality when group member's location of user equipment changes, and the maintenance business is not interrupted.
PoC service is one of main business that is defined in the IMS territory.It provides the point-to-multipoint half-duplex operation function of similar trunking communication, and the voice communication of point-to-multipoint mainly is provided, communication be pre-defined at one or the group of temporarily convening in carry out.At synchronization, can only there be a user to talk at most, other users can only answer speech.In the similar communication mode after expansion, can provide communicating by letter of multiple media formats such as note, image and Streaming Media, but communication mode still is a point-to-multipoint.
In the existing standard of 3GPP, introduced the defined PoC service standard of OMA (Open Mobile Association Open Mobile Alliance), and realized PoC service in the IMS territory.According in the agreement " 3GPP TR23.979:3GPP enablersfor OMA PoC Services " to the description of PoC service, PoC service will utilize a plurality of functions of IMS to realize as an application under the IMS architecture.
Fig. 1 illustrates each processing module of PoC service under the IMS framework.The PoC server is as an application server (AS, Application server), and the processes such as discovery of the registration of PoC service, PoC server are substantially all applied mechanically the existing IMS process of 3GPP, has simplified the design work amount that PoC service is realized.Is, If interface use the SIP/SDP agreement to carry out the management of signaling plane, on the basis of standard agreement, have carried out a small amount of expansion at the PoC service feature; Use the RTP/RTCP agreement to carry out user plane data transfer and control and management at It, Itn interface, on RFC3550 and relevant RFC basis, carried out a spot of optimization.
PoC server (PoC Server) is realized the network function of application layer, is equivalent to an application server.Connect by ISC interface between IMS core and the PoC server, ISC interface defines at 3GPP TS23.228.
PoC user uses GLMS (Group List Management Server group list management server) to manage group and tabulation, use Ut to be connected with Presence Server (presence server), PresenceServer provides the effective information between PoC user, specifically defines at TS23.141.
Prior art mainly realizes the control logic of PoC service by the service control function in IMS territory, the control of carrying is owing to the restriction that is subjected to WCDMA carrying design itself uses the carrying of traditional point-to-multipoint to finish the business of the point-to-multipoint of PoC.This mode makes carrying set up and control flow is not optimized at the characteristic of PoC service, causes and can't carry out corresponding control and satisfy the specific (special) requirements of this business to QoS at the PoC service type.

Embodiment
Technical conceive of the present invention is to realize PoC service by the control of Access Network side that concrete control method comprises following two steps:
When PoC service is in state of activation, the right of speech free time of monitoring PoC service, when free time reaches setting threshold, with each member in the group from dedicated channel CELL_DCH state transition be paging channel CELL_PCH state and discharge and each group member between Radio Resource;
After the Radio Resource of PoC service is released, each member's state in the monitoring group, other group member of paging and according to the Radio Resource between the group member that the configuration parameter of preserving in advance rebulids and caller and paging are arrived when speech is initiated in caller activates PoC service with each member after the CELL_DCH state is returned in CELL_PCH state transition.
The Radio Resource that needs to discharge in said process or set up comprises: Radio Link and radio bearer.
For realizing above-mentioned technical conceive, the Access Network side must be user's start that adds the PoC group or interim the establishment immediately, and promptly setting up in the process of PoC session (Session) knows that clearly this conversation type is a PoC service.Therefore the present invention sets up the corresponding cause value that has increased indication PoC service type in the related news that transmit in the process at PoC session, make Access Network judge the content PoC service type that changes according to the cause value that carries, the idiographic flow that PoC session is set up comprises the steps: as shown in Figure 2
When any one group member of S101, PoC service initiates PoC service as the calling subscriber, calling UE (User Equipment, subscriber equipment) connects and set up the corresponding cause value that carries indication PoC service type in the request message sending to the RRC of UTRAN (Radio ResourceControl, Radio Resource control);
UTRAN can set up this cause value that carries in the request message according to the RRC connection and confirm that the type of service of this foundation is a PoC service;
S102, UTRAN return the RRC connection to UE and set up message;
UE sets up the Radio Link with WCDMA Access Network side;
S103, initial direct-sending, direct-sending message up and down;
In this step, carry out the mutual of non-access layer information between UE and WCDMA Access Network side, it is PoC service that the core net CN of WCDMA can judge the type of service of setting up by some information of Non-Access Stratum, and sends corresponding RAB assignment messages according to the service needed of UE.
S104, CN send RAB (Radio Access Bearer, RAB) assignment messages to UTRAN, can carry the corresponding cause value of indication PoC service type in this message equally;
For example increase IE:Service Specified indication territory in this message, this indication territory is 8bit, can be used to carry corresponding cause value;
In like manner, also can revise at RAB and carry corresponding cause value in the message, it is the standard message of 3GPP that RAB revises message, but the parameter of service bearer to change be need carry out RAB to revise.Speed such as voice becomes 10.2K etc. from 12.2k.
The RAB assignment messages requires UTRAN to set up RAB for this caller, for follow-up normal conversation is got ready, UTRAN is after the RAB assignment messages of receiving from CN, actions such as the passage by foundation is admitted, resource negotiation, send Radio Link to user place sub-district NodeB (base station) again and set up request message, Node B returns a Radio Link to UTRAN and sets up response message after finishing Radio Link foundation smoothly.Then:
S105, UTRAN send radio bearer (RB) to UE and set up message;
S106, UE utilize the parameter of PoC session to finish about disposing and returning radio bearer foundation to UTRAN and finish message;
S107, UTRAN send RAB to CN and assign response message, show that RAB is set up to finish.
Except in above-mentioned two message, carrying corresponding cause value UTRAN is known the type of service, PoCSERVER also can by the SIP signaling channel set up or other passages directly and UTRAN carry out alternately, directly notify the UTRAN type of service, advice method can be the packet that sends the agreement form, the packet that for example has particular ip address or expression, UTRAN can be known type of service after receiving the packet of this agreement form, and finishes for PoC SERVER alternately by these channel return messages.
Simultaneously, other group member of UTRAN paging, and set up RRC connection, Radio Link and the radio bearer of other member in each group respectively, the speech data of caller can be sent to other member in each group then.
If caller stops to send speech data, discharge right of speech, UTRAN begins to monitor the right of speech free time of PoC service, when described free time reaches setting threshold, as shown in Figure 3, by following step with each group member from CELL_DCH state transition to the CELL_PCH state and discharge Radio Resource:
S201, UTRAN begin to monitor right of speech free time after caller discharges right of speech;
S202a1, S202a2, when free time reaches setting threshold, issue and require it to move to the Indication message of CELL_PCH state to each group member's user terminal;
S202b1, S202b2, UTRAN discharge each group member's Radio Resource, comprise Radio Link and radio bearer;
Step S202a1 and S202b1 can carry out synchronously, and S202a2 and S202b2 can carry out synchronously.
After S2031, S2032, each group member receive the CELL_PCH state indication message, change the CELL_PCH state into.
The scope of right of speech free time threshold value can determine that this paper does not specifically limit according to carrier policy.
After Radio Resource was released, each member was in the CELL_PCH state in the group, if there is the user to initiate speech (seizing right of speech), the user was moved back CELL_DCH from CELL_PCH.In order to satisfy PoC service to robbing the requirement of temporary prolonging, need fast each group member from the CELL_PCH state to move back the CELL_DCH state, in transition process, the Radio Resource that the needs reconstruction has been released, for shortening the process of reconstruction of Radio Resource, the present invention adopts the parameter pre-deployment.
Owing to use the PoC service of voice, its business configuration parameter generally is relatively more fixing.Therefore can use pre-configured technology, the business configuration parameter of PoC is stored among UE and the UTRAN in advance, and every suit parameter distributed an ID sign, in each professional foundation, it is just passable only to need UTRAN that the ID of stored parameter sign is issued UE like this.Use the pre-configured size that can reduce space interface signaling, reduce the signaling transmission time, reduce time delay.Realize the pre-configured multiple mode that comprises:
1, default configuration: the subscriber equipment and the UTRAN that are stored in each member in the group in advance, if both sides have preserved many covers configuration parameter simultaneously, then unique sign is set for every suit configuration parameter, when setting up this button and promptly say business, UTRAN sends to the sign of the configuration parameter of this use the subscriber equipment of each member in the group;
2, stored configuration: issue button when the subscriber equipment access network by UTRAN and say professional configuration parameter information, and network side and subscriber equipment are preserved synchronously, every cover configuration parameter is provided with unique parameter identification, follow-up when setting up described button and promptly saying business at every turn, UTRAN sends the relevant parameter sign, and each Member Users's equipment and UTRAN set up Radio Resource according to described parameter identification configuration parameter corresponding in the group; And if the UTRAN update configuration parameters, the subscriber equipment that parameter after then will upgrading and corresponding parameters sign send to each member in the group upgrades synchronously;
3, parameter is preserved automatically: each member's subscriber equipment is preserved respectively and was successfully set up the configuration parameter that described button is promptly said business last time in UTRAN and the group, and when setting up this button and promptly say business next time, if configuration parameter is not changed, then both sides use the configuration parameter of preservation last time to set up Radio Resource; Otherwise the parameter information that UTRAN will need earlier to change sends to after each member's subscriber equipment upgrades corresponding parameter, and both sides set up described button with the configuration parameter after upgrading again and promptly say professional.
As shown in Figure 4, adopt the pre-configured technology of above-mentioned parameter after, when the calling subscriber occurring and initiate to talk, the idiographic flow that the calling subscriber is returned the CELL_DCH state from CELL_PCH state transition comprises the steps:
S301, caller send Cell Update (cell update) message to the UTRAN side on forward access channel FACH, carry the cause value that indication activates PoC service in this Cell Update message;
S302a, UTRAN lateral root comprise rebuliding Radio Link and radio bearer according to rebuliding Radio Resource between the configuration parameter of this PoC service and the caller;
S302b, UTRAN side issue the Cell Update Confirm (cell update affirmation) that carries the CELL_DCH status indication information to caller on the FACH channel;
Step S302a and S302b can carry out simultaneously, and parameter is pre-configured owing to having carried out, and have therefore omitted the RB reconfiguration course, have shortened the process of rebuilding Radio Resource.
Caller is the CELL_DCH state according to described CELL_DCH status indication information from the CELL_PCH state-transition;
S303, caller are returned physical channel to UTRAN and are reshuffled and finish message PHYSICAL CHANNEL RECONFIG CMP on the DCH channel, the subscriber equipment that is used for the group member tells the Access Network side its wireless channel of having set up according to configuration requirement, and this message tells group member's subscriber equipment to set up successfully.
As shown in Figure 5, other group member of UTRAN synchronous paging and with paging to group member's process of returning the CELL_DCH state from CELL_PCH state transition comprise following substep:
S401, UTRAN be broadcast paging messages Paging Typel on paging channel PCH, carries the cause value that indication activates PoC service in this PagingTypel message;
S402, paged to the group member on the FACH channel, send Cell Update message to the UTRAN side, carry the cause value that indication activates PoC service in this Cell Update message;
S403a, UTRAN lateral root are according to the configuration parameter of this PoC service and return between each member of Cell Update message and rebulid Radio Resource;
S403b, UTRAN side issue the Cell Update Confirm that carries the CELL_DCH status indication information to each member on the FACH channel;
Equally, step S403a and S403b can carry out simultaneously, owing to adopted parameter pre-configured, have omitted the RB reconfiguration course, have shortened the process of rebuilding Radio Resource.
Each member who returns Cell Update message is the CELL_DCH state according to described CELL_DCH status indication information from the CELL_PCH state-transition.
S404, each member return PHYSICAL CHANNELRECONFIG CMP to UTRAN on the DCH channel.
From above-mentioned flow process as seen, can carry out specific special processing to PoC service in order to make UE and UTRAN, need indicate type of service when business is initiated, processing entities could be distinguished out PoC service and non-PoC service like this, handles respectively.Therefore, the cause value that needs two message of expansion.Article one, be CellUpdate message, when UE is in the CELL_PCH state, when the user initiates to rob right of speech, will on the RACH channel, send Cell Update message, cause value in the message is set to Active PoC Session (activation PoC session), on an existing basis one of expansion new value.Another message is Paging Typel, when UTRAN needs paging to be in the group user of CELL_PCH state, need use the cause value Active PoC Session of expansion in sending PagingTypel message.
To sum up, the solution of the present invention is mainly improved the handling process of Access Network part in the PoC service activation, realizes the forever online of PoC user, satisfies the requirement of PoC user to service quality.
After PoC Session set up, PoC user was in the permanent presence of WCDMA, was in CELL_DCH state or CELL_PCH state at Access Network.When having the user to talk, the user is in the CELL_DCH state in all groups.There not being the user to talk behind the certain hour, the user is moved to the CELL_PCH state from CELL_DCH, discharge interface-free resources.The user only is in one of these two states in whole PoC Session, on the basis of not wasting interface-free resources, realized that PoC user's is forever online.
As shown in Figure 6, the control system that realizes technique scheme of the present invention comprises the UTRAN100 that is positioned at the Access Network side and user group member's subscriber equipment 200; Wherein:
Comprise following structure among the UTRAN100:
