Description
Technical field
The embodiment of the invention relates to communication technical field, particularly a kind of resource allocation methods, access network equipment node and trunked communication system.
Background technology
Development along with mobile communication technology, the application of mobile communication is also in continuous expansion, such as, trunking communication, claim again " PTT (Push to Talk, PTT) " be a kind of of mobile communication, be characterized in that call set-up time is short, ability busy channel when speaking, a monitor channel when answering, the recipient does not need off-hook can answer descending call information at any time.
PTT business based on public's cellular mobile communication networks is called PoC service, i.e. Push to talk over Cellular.This business utilizes public's mobile cellular network to cover wide characteristics, makes the mobile subscriber realize a little arriving the group call of multiple spot, thus between many people effectively, sharing information in time.PoC service can make the user " online all the time " of group call, this " online all the time " if characteristics make the member who participates in conversation press the PTT key can to converse.One of key business characteristic of above-mentioned group service is exactly the requirement for time delay, also promptly sends request until receiving that the time that network side allows its speech to indicate can not be above 1 second when the user presses key.
For the user provides business service, adopt three kinds of modes to transmit data at present, first kind of mode for well: all to use dedicated channel transmission data at up direction and down direction.When one group of user carries out trunking communication, each user sets up dedicated channel (the Dedicated Channel of oneself, DCH), be that network is that the user distributes DCH respectively at up direction and down direction, user by own special uplink channel transmission speech data to network, network sends to all listening users again the voice signal that receives from organizing the interior pairing dedicated channel of other user.The second way: down direction adopts common signal channel transmission data, and up direction obtains Random Access Channel by the mode of competition, and (RandomAccess Channel, right to use RACH) is transmitted data.At down direction, the transmission channel that mobile communication system can be used jointly for all user's configurations, such as, the forward access channel of down direction (Forward Access Channel, FACH) or high-speed downlink shared channel (High Speed-Downlink Shared Channel, HS-DSCH), the data of transmitting on the common down channel can be answered by all users that can receive FACH or HS-DSCH channel simultaneously; At up direction, obtain usufructuary user and can on RACH, send data to access network equipment node.But, because user priority information belongs to the part of user signing contract information, these precedence informations only are stored in core net node, after the user must connect with core net earlier, core net could judge whether according to user's priority right of speech is authorized to the user, and promptly the decision node seized of the up cluster Session Resources of cluster user is a core net node.Just, when one group of user carried out trunking communication, the user sent speech data to network by using up Random Access Channel RACH, and network sends to other interior users of group to the speech data that receives by descending FACH channel again.The third mode: down direction is similar to the down direction in the second way, also uses common signal channel transmission data; Up direction is similar to the up direction in first kind of mode, and each user also uses dedicated channel transmission data, and the request of right of speech and grant information are all transmitted on the DCH channel.
But the inventor finds that in the process of implementing technical solution of the present invention there are some defectives in prior art: for example, use dedicated channel transmission data, can consume the most of channel resource in the mobile communication system, have a strong impact on intrasystem other professional transmission; And, when each user joins in this cluster session, need between user and the network side through paging, Radio Resource control (Radio Resource Control, after the processes such as RRC) connection is set up, channel is reshuffled, subscriber terminal equipment (UE) can normally be carried out the needed dedicated channel resource of session, the needed time of this process needs much larger than the time delay for group service, has had a strong impact on user's impression.In addition, RACH inserts the method that the mode belong to by fair competition obtains to send the qualification of data, even and think that all users' priority is identical, if exist two or more users to initiate to insert and use same access signature in the same moment, then this several users can all can not obtain to send qualification because of conflict has taken place, and this resource that this signature is corresponding constantly causes waste because of not used by the user equally; In addition,, need be divided into repeatedly and to send, but because a plurality of user's competitive channels are arranged if the user has a bigger packet, thus can not guarantee this user each the time can both obtain to send the chance of data, the time delay that sends this packet will be very big.Therefore, the conflict that takes place in the fair competition has reduced the utilization ratio of channel resource and the speed that data send, and has strengthened the conversation time delay, has influenced speech quality, has reduced user's Experience Degree.

Step a, receiving the user is the solicited message of the up cluster Session Resources of cluster session application.
Step b is that above-mentioned cluster session distributes public up cluster Session Resources according to above-mentioned solicited message.
In the specific implementation process, can finish above-mentioned steps a and step b by access network equipment node.Need to prove, the access network equipment node of mentioning among all embodiment of the present invention is different network elements in different communication systems, for example at universal mobile telecommunications system (Universal Mobile Telecommunications System, UMTS) in radio network controller (Radio Network Controller, RNC), in the LTE system be evolution base station (Evolved NodeB, eNB).
Above-mentioned access network equipment node can receive the solicited message of a plurality of up cluster Session Resources, and is respectively each cluster session according to the cluster session identification that carries in these a plurality of solicited messages and respectively distributes a public up cluster Session Resources.
Above-mentioned resource allocation methods, distribute a public up cluster Session Resources by being respectively each cluster session, rather than distribute a up private resource respectively for each user in each cluster session, thereby improved the utilization ratio of channel resource greatly, reduced the conversation time delay, improve speech quality, improved user's Experience Degree.
As shown in Figure 2, be the flow chart of resource allocation methods embodiment two of the present invention, this method comprises:
If the user has been assigned with the cluster session identification, then carry the cluster session identification in the up cluster Session Resources solicited message that access network equipment node receives.Above-mentioned up cluster Session Resources is used for the business datum of transmission trunking session.
The cluster session identification that the user is assigned with, can be when the up cluster Session Resources of user's first application be its distribution by access network equipment node or equipment of the core network node; Also can be in the registration attaching process after the user start, be its distribution by the equipment of the core network node; Can also be that the core net device node is its distribution in the process that the periodicity routing region updating of user and core net or registration area upgrade; Perhaps, the user is when networking, and with the cluster session identification of consulting in the operator signatory process to be participated in, the user can carry this cluster session identification when the up cluster Session Resources solicited message of initiation like this.
If be not assigned with the cluster session identification before the user, then access network equipment node is not carried out above-mentioned determining step, user's Non-Access Stratum can carry the identification information of cluster session, and network side distributes other cluster session identification of Access Layer level by the Non-Access Stratum process for the user.
Step 103 for above-mentioned cluster session distributes up cluster Session Resources, and indicates above-mentioned user to use this up cluster Session Resources to carry out the transmission of cluster session data.
If above-mentioned user is first user of the up cluster Session Resources of application in this cluster session, then the user uses above-mentioned up cluster Session Resources to carry out the transmission of cluster session data according to the indication of access network equipment node.Above-mentioned up cluster Session Resources can be up dedicated channel.
Step 105 sends the indication information that uses above-mentioned up cluster Session Resources to transmit above-mentioned cluster session data to above-mentioned user.
Further, step 106 specifically can comprise:
If the user of the up cluster Session Resources of application and the current user's who takies above-mentioned up cluster Session Resources priority is inequality in the step 101, then indicate low priority user to stop using above-mentioned up cluster Session Resources, and the indication high-priority users is used above-mentioned up cluster Session Resources; If above-mentioned two users' priority is identical, then indicate the user of the up cluster Session Resources of application in the step 101 can not use ascending resource transmission data, perhaps the request of applying for the user of ascending resource in this step 101 is not responded.The user of application ascending resource can start a timer in the above-mentioned steps 101, does not but receive the response of access network equipment node if this timer expires, and then judges this time up cluster Session Resources application failure.
Before step 106, can also comprise: the precedence information that obtains user in the above-mentioned cluster session.Concrete acquisition methods can comprise: receive the precedence information etc. of the user the above-mentioned cluster session from equipment of the core network.For example, after access network equipment node receives user's up cluster Session Resources solicited message, if judging above-mentioned user is that first of this cluster session identification applied for the user of up cluster Session Resources, then this access network equipment node receives the precedence information of the user the above-mentioned cluster session from equipment of the core network; Again for example, if the up cluster Session Resources that above-mentioned cluster session distributes is not idle, then access network equipment node can receive the user priority information of above-mentioned cluster session identification from core net.
Before above-mentioned access network equipment node received the precedence information of the user the above-mentioned cluster session from the core web network equipment node, access network equipment node can send the precedence information of the user in the above-mentioned cluster session and/or the service profile that other clusters are correlated with by active request core web network equipment node.
Above-mentioned resource allocation methods, by judging whether the user who applies for up cluster Session Resources is the user of first initiation in the above-mentioned cluster session, if, it then directly is this user's assigned with dedicated channel, otherwise, need further to judge whether the up cluster resource of above-mentioned cluster session correspondence is idle:, then indicate the user to use if idle, otherwise, then judge according to user's precedence information whether this user can seize current occupied up cluster Session Resources.Seize a up cluster Session Resources by a plurality of users in the cluster session and carry out transmitting uplink data, and the decision node that the up cluster Session Resources of cluster user is seized is transferred to access network equipment node from the core web network equipment node, improved the utilization ratio of channel resource greatly, reduce the conversation time delay, improved user's Experience Degree.
