Embodiment
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with embodiment and accompanying drawing, the present invention is described in more detail.
In the present invention, terminal carries out reporting of cluster channel head compression tenability after connecting with network, core network subsystem reporting according to terminal, determine the cluster channel head compression tenability of cluster group, if in cluster group be all ability terminal, then adopt header compression mode to carry out data distributing, if there is capabilities terminal in cluster group, then do not adopt header compression mode to carry out data distributing to all terminals; Thus, ensure that all terminal equipments all downlink data receivings in cluster group, and improve the bandwidth availability ratio of air interface as far as possible.
See Fig. 1, for carrying out the method indicative flowchart of a compressed configuration in group service of the present invention, it comprises the following steps:
Step 101, the cluster channel head compression tenability reported after network connects set up by receiving terminal.
After terminal sets up network connection, report the cluster channel head compression tenability of self to core network subsystem; Described set up situation that network connects as: start, terminal to move to the region etc. of quorum sensing inhibitor from the region of no signal.
The cluster channel head compression tenability of terminal to report self, various ways can be adopted to realize, and the mode by base station transfer reports core network subsystem, also directly can report core network subsystem.Be illustrated below:
Mode one: after terminal sets up network connection, at wireless heterogeneous networks (RRC, RadioResourceControl) the group service channel head compression tenability of self is carried in message, report base station, group service channel head compression tenability is carried in S1 message by base station, reports core network subsystem.Described RRC information is concrete as terminal ability information (UECapabilityInformation), and described S1 message is specifically as terminal ability information instruction.
Mode two: for employing Non-Access Stratum (NAS, Non-AccessStratum) situation of agreement, terminal after the network connection established, at Non-Access Stratum (NAS, Non-AccessStratum) carry the group service channel head compression tenability of self in protocol message, report core network subsystem; Described NAS protocol message can be existing NAS protocol message, also can be the NAS protocol message of new definition.
Step 102, reporting according to terminal, judges whether all online terminal in cluster group all supports the compression of cluster channel head, if so, then determines that the cluster channel head compression tenability of this cluster group is for supporting; Otherwise, determine that the cluster channel head compression tenability of this cluster group is not for support.
The cluster channel head compressed capability of cluster group is determined by the tenability of online terminals all in this cluster group, if all online terminals are all supported, then determines that the cluster channel head compression tenability of this cluster group is for supporting; If have more than one not support in online terminal, then determine that the cluster channel head compression tenability of this cluster group is not for support.
Step 103, carries out cluster multi call when setting up, and the cluster channel head of cluster group compression tenability is sent to base station, to open or to close head compression, carries out data distributing.
The cluster channel head of cluster group compression tenability is sent to base station, various ways can be adopted to realize, such as, in the call setup message issuing base station, carry the cluster channel head compression tenability of cluster group.
After the cluster channel head compression tenability knowing cluster group is obtained in base station, corresponding unlatching or the compression of closedown head; Particularly, if for supporting, then opening head compression, adopting header compression mode to carry out data distributing; If for not support, then close head compression, do not adopt header compression mode to carry out data distributing.
Head compression is opened or closed in base station, according to the cluster channel head compression tenability in call setup message, and all online terminal under head compressed configuration being informed to this base station in this cluster group; Data distributing is carried out to online terminals all in cluster group in base station.
Further, also can according to the dynamic change of terminal in cluster group, correct compressed configuration adjusts.Two kinds of situations are divided to be illustrated below.
Situation one,
Before carrying out cluster multi call foundation, the method also comprises:
Monitor former not online terminal in cluster group to become online or former online terminal and become not online, then judge whether all online terminal current in cluster group all supports the compression of cluster channel head, if so, then determine that the cluster channel head compression tenability of this cluster group is for supporting; Otherwise, determine that the cluster channel head compression tenability of this cluster group is not for support;
With current determine should and group cluster channel head compression tenability upgrade former cluster channel head compression tenability.
Situation two,
After the cluster channel head of cluster group compression tenability is sent to base station, the method also comprises:
Monitor former not online terminal in cluster group to become online or former online terminal and become not online, then judge whether all online terminal current in cluster group all supports the compression of cluster channel head, if so, then determine that the cluster channel head compression tenability of this cluster group is for supporting; Otherwise, determine that the cluster channel head compression tenability of this cluster group is not for support;
Former cluster channel head compression tenability is upgraded by the cluster channel head compression tenability of current this cluster group determined; And when the cluster channel head compression tenability of this cluster group changes and this cluster group is carrying out group calling, the change of signalling of bouquet channel head compression tenability is indicated to base station, changes to carry out a compressed configuration.
In the present invention, the cluster channel head compression tenability reported after network connects set up by receiving terminal; Reporting according to terminal, judges whether all online terminal in cluster group all supports the compression of cluster channel head, if so, then determines that the cluster channel head compression tenability of this cluster group is for supporting; Otherwise, determine that the cluster channel head compression tenability of this cluster group is not for support; Carry out cluster multi call when setting up, the cluster channel head of cluster group compression tenability is sent to base station, then, base station just can determine whether to open head compression according to cluster channel head compression tenability.Like this, if in cluster group be all ability terminal, then adopt header compression mode to carry out data distributing, if there is ability terminal and capabilities terminal in cluster group simultaneously, then do not adopt header compression mode to carry out data distributing; Thus, ensure that all terminal equipments all downlink data receivings in cluster group, and improve the bandwidth availability ratio of air interface as far as possible.Further, before the present invention adopts terminal after connecting with network, cluster multi call sets up, carry out capability reporting, report before action occurs in group-calling service, do not affect call set-up time.
Below by the flow process of Fig. 2, give example to the method for carrying out a compressed configuration in group service of the present invention and illustrate, it comprises the following steps:
Step 201, terminal carries self in terminal ability information group service channel head after setting up network connection compresses tenability, reports base station.
Step 202, group service channel head compression tenability is carried in terminal ability information instruction by base station, reports core network subsystem.
Step 203, core network subsystem reporting according to terminal, judges whether all online terminal in cluster group all supports the compression of cluster channel head, if so, then determines that the cluster channel head compression tenability of this cluster group is for supporting; Otherwise, determine that the cluster channel head compression tenability of this cluster group is not for support.
Step 204, core network subsystem monitors former not online terminal in cluster group and becomes online or former online terminal and become not online, then judge whether all online terminal current in cluster group all supports the compression of cluster channel head, if so, then determine that the cluster channel head compression tenability of this cluster group is for supporting; Otherwise, determine that the cluster channel head compression tenability of this cluster group is not for support.
Former not online terminal becomes online, as starting up of terminal, or moves to the region of quorum sensing inhibitor from the region of no signal.Former online terminal becomes not online, as terminal closedown etc.
Core network subsystem detects that in cluster group, the online situation of terminal changes, then adopt the scheme of step 203 to redefine the current cluster channel head compression tenability of cluster group.
Step 205, the current cluster channel head compression tenability determined of core network subsystem upgrades former cluster channel head compression tenability.
Step 204-205 is that the group ability in non-call changes situation.
Step 206, carries out cluster multi call when setting up, and core network subsystem, in the call setup message issuing base station, carries the cluster channel head compression tenability of cluster group.
Step 207, the cluster channel head compression tenability of cluster group is known in base station from call setup message, if for supporting, then opens head compression, and all online terminal under head compressed configuration being informed to this base station in this cluster group, adopt header compression mode to carry out data distributing; If for not support, then close head compression, and all online terminal under head compressed configuration being informed to this base station in this cluster group, do not adopt header compression mode to carry out data distributing.
Step 208, core network subsystem monitors former not online terminal in cluster group and becomes online or former online terminal and become not online, then judge whether all online terminal current in cluster group all supports the compression of cluster channel head, if so, then determine that the cluster channel head compression tenability of this cluster group is for supporting; Otherwise, determine that the cluster channel head compression tenability of this cluster group is not for support.
Core network subsystem detects that in cluster group, the online situation of terminal changes, then adopt the scheme of step 203 to redefine the current cluster channel head compression tenability of cluster group.
Step 209, the core network subsystem cluster channel head compression tenability of current this cluster group determined upgrades former cluster channel head compression tenability; And when the cluster channel head compression tenability of this cluster group changes and this cluster group is carrying out group calling, the change of signalling of bouquet channel head compression tenability is indicated to base station.
If the cluster channel head compression tenability of this cluster group changes, core network subsystem also sends to base station and changes instruction.
Step 210, after base station receives and changes instruction, correct compressed configuration changes, and all online terminal under head compressed configuration Notification of Changes being given this base station in this cluster group, adopt the mode after changing to carry out data distributing.
Step 208-210 is that the group ability in calling changes, and comprises two kinds of situations:
If a core network subsystem is according to the judgment principle of above-mentioned steps 203, judge that the head packed attribute of certain cluster group becomes " not supporting that cluster channel head compresses " from " supporting the compression of cluster channel head ", and this group carries out group calling, then this attribute should be changed informing base station by core network subsystem, the data compression scheme of group service channel should compress become from use head and not use head to compress by base station, and this compressed configuration is changed the terminal notifying this group.
If b core network subsystem is according to the judgment principle of above-mentioned steps 203, judge that the head packed attribute of certain cluster group becomes from " not supporting that cluster channel head compresses " " supporting the compression of cluster channel head ", and this group carries out group calling, then this attribute should be changed informing base station by core network subsystem, the data compression scheme of group service channel never should use head compression to become and use head compression by base station, and this compressed configuration is changed the terminal notifying this group.
Owing to supporting that the terminal of cluster channel head compression also can receive the data do not compressed, therefore, for above-mentioned b situation, this attribute can not be changed informing base station by core network subsystem; Base station can not change the head compressed configuration of downlink data.
Lower mask body is for time-division Long Term Evolution (TD-LTE, TimeDivision-LongTermEvolution) group service, and the method for the present invention being carried out to a compressed configuration is described further.
Assuming that cluster group A comprises 3 UE, be respectively UE1, UE2 and UE3, wherein, UE1, UE2 support group service channel (TTCH, TrunkingTrafficChannel) PDCP (PDCP, PacketDataConvergenceProtocol) head compression, UE3 does not support that the PDCP head of TTCH compresses.
Group ability in scene 1:[UE capability reporting, non-call changes]
After 1.1UE1 start performs attachment (Attach) process, by " supporting the PDCP head compression of TTCH " capability reporting to core net.
Reporting schemes in this example is, UE1 trigger base station (eNodeB) initiating terminal capable transport (UECapabilityTransfer) process after Attach process, ability reports by UE1 in terminal ability information (UECapabilityInformation), eNodeB terminal ability information instruction (UECapabilityInfoIndication) in by this capability reporting to core network subsystem.
The UECapabilityInformation structure of 3GPP definition is as follows, wherein comprises UE-CapabilityRAT-ContainerList cell.Comprise sub-cell ueCapabilityRAT-Container in the structure of this cell, form is OCTETSTRING, can carry the ability that UE supports the compression of group service channel head in this sub-cell.
In above-mentioned UECapabilityInformation structure, the part indicating underscore has indicated its UE-CapabilityRAT-ContainerList cell comprised.Provide the structure of UE-CapabilityRAT-ContainerList cell below:
In the structure of above-mentioned UE-CapabilityRAT-ContainerList cell, the part indicating underscore has indicated the sub-cell of ueCapabilityRAT-Container wherein, its form is OCTETSTRING, can carry the ability that UE supports the compression of group service channel head in this sub-cell.
Natch, above-mentioned UECapabilityInformation structure is an example, is not limited in this.
1.2 core network subsystem are according to judgment principle, and UE (only having UE1) online in cluster group A supports that the PDCP head of TTCH compresses, so the attribute of cluster group A is " the PDCP head compression supporting TTCH ".
1.3UE2 starts shooting, and incites somebody to action " the PDCP head compression supporting TTCH " capability reporting to core network subsystem according to the method for step 1.1.
1.4 core network subsystem are according to judgment principle, and UE (UE1, UE2) online in cluster group A all supports that the PDCP head of TTCH compresses, so the attribute of cluster group A still remains " the PDCP head compression supporting TTCH ".
Scene 2:[call setup]
2.1UE1, UE2 start shooting all, and the attribute of cluster group A is " the PDCP head compression supporting TTCH ".
2.2UE1 initiates group calling to cluster group A and sets up.
2.3 core network subsystem instruction eNodeB set up group call resource, and indicate the attribute of cluster group A to be " the PDCP head compression supporting TTCH ".
After 2.4eNodeB sets up group calling, send out broadcast to cluster group A, indicate this calling to use the compression of PDCP head.
2.5eNodeB enables the PDCP head compression of TTCH, and the PDCP head that UE1, UE2 enable TTCH decompresses.
Clustering capability in scene 3:[calling changes]
3.1UE1, UE2 start shooting all, and UE1 initiates group calling to cluster group A and sets up, and eNodeB has enabled the PDCP head compression of TTCH.
3.2UE3 starts shooting, according to the method for step 1.1 capability reporting of " not supporting that the PDCP head of TTCH compresses " to core network subsystem.
3.3 core network subsystem are according to judgment principle, UE (UE1, UE2, UE3) existence online in cluster group A does not support the UE (UE3) that the PDCP head of TTCH compresses, so the attribute changes of cluster group A is " not supporting that the PDCP head of TTCH compresses ".
The attribute of cluster group A should be changed instruction eNodeB by 3.4 core network subsystem.
Wherein a kind of possible indicating mode is, core network subsystem is sent out S1 message instruction eNodeB and revised the cluster set up and exhale context, and the attribute carrying cluster group A in this S1 message is " not supporting that the PDCP head of TTCH compresses ".
3.5eNodeB receives above-mentioned S1 message, closes the PDCP head compression of TCCH, and sends out broadcast to cluster group A, indicate this calling not use PDCP head to compress.
3.6UE1, UE2, UE3 use non-compressed mode to receive TTCH data.
