- Process 60 is a scheme for conducting radio access network packets.
- Fig. 6 the same or similar portions as those in Fig. 5 are denoted by the same reference numerals, and the description will not be repeated.
- S61 at UTRAN or E-UTRAN is re-grouped at the wireless access network.
- the re-grouping of the radio access network can perform access control according to the load of the RAN, and effectively reduce the occurrence of collisions during access.
- the RAN combines with TMGI by setting access parameters to trigger and control access by group users. For example, the user is re-grouped using the TMGI and the access parameters, and the UE determines whether to initiate the access based on the received TMGI and the access parameters.
- the RAN may set an access parameter for controlling access of the UE according to the load of the cell and the number of UEs belonging to the TMGI in the cell, or according to the load of the cell, and carry the access parameter in the MCCH message.
- Access parameters include a number of different methods and their combinations: such as access probability factor, modulo, length of time allowed for access, and so on.
- the RAN packet can be further accurately performed according to the current network load situation and the number of users, and the method for obtaining the group related information of the cell user is as follows:
- the first category is to obtain information from the CN (Core Network) node and ⁇ or server. This method is suitable for applications with fixed terminal locations, such as smart meter reading. At this time, the location information update frequency is low, so the related information can be stored, periodically or event triggered for update.
- the second type is to obtain corresponding information from the UE.
- This method is also applicable to scenes where the terminal position moves.
- the UE notifies the RAN related packet information, and can update the packet information.
- it is necessary to notify the UE of the corresponding access parameters. Specifically, after receiving the Session Start Request message, if the RAN saves the user situation of the packet in the current cell, or obtains the packet user status of the current cell from other nodes, the RAN according to the current cell load condition and the The number of current cell users in the packet is calculated, and the access parameter is calculated, and the UE is notified by adding access parameter information in the MBSFNAreaConfiguration message.
- the RAN After the RAN receives the Session start Request message, if the user situation of the packet in the current cell is not retained and the packet user situation of the current cell cannot be obtained from other nodes, the RAN sets the access parameter according to the load condition of the current cell, and passes the MBSFNAreaConfiguration. Notify the UE.
- the RAN can adjust subsequent access parameters according to the number of previous successful access users, access parameters, and network load changes.
- S62 and S63 are similar to S58 of Fig. 5, respectively. However, in S62 and S63, according to the re-grouping of the access network, each re-packet UE is triggered to access, and after the access is successful, a connection is established and data transmission is performed at S64 and S65 respectively. S64 and S65 are also similar to S59 of Figure 5, respectively.
- the RAN informs the UE that the packet triggers the end of the access and translates the related resources.
- the RAN may also trigger the Session Sto message itself after satisfying certain stopping conditions (the stopping conditions may be multiple: the number of users that are triggered to access is 0, all users have accessed, etc.).
- the stopping conditions may be multiple: the number of users that are triggered to access is 0, all users have accessed, etc.).
- a single call is initiated by the network or an access request is initiated by the UE itself. It is also possible to not send a packet to trigger an access end message, and use a special access parameter as the end identifier of the current packet trigger access. The UE does not notify the UE to trigger the access end message, and the UE itself determines.
- the UE may listen to the corresponding MCCH, receive the MBSFNAreaConfiguration message, and perform calculation according to the access parameters included therein to determine whether to initiate access, for example, determining to initiate access or continue to listen to the MCCH. Specifically, if the UE successfully initiates the access once, the access of the same group is not initiated in the subsequent process until the termination message is received or the relevant packet is not triggered within a certain period of time. If the UE does not successfully initiate the access, it continues to listen to the corresponding channel, and then accesses in the subsequent packet triggering access process.
- the UE may initiate an access request by itself or wait for a page of the network to initiate an access request.
- the special access parameter can be used as the end identifier of the packet trigger access.
- the process 60 according to the embodiment of the present invention adopts a radio access network re-packet scheme, which can quickly and effectively control the load of the radio access network, and can effectively reduce the occupation of the downlink channel.
- the embodiment of the present invention can also perform packet triggering access by using the Counting mechanism in the MBMS.
- the RAN node after receiving the Session Start Request message from the upstream node, the RAN node triggers the Counting mechanism to send an MBMS Counting Request message to the UE as a trigger access message.
- the Counting mechanism here is different from the normal Counting mechanism of MBMS. It uses an enhanced Counting mechanism to implement access networks for all users. After all or most of the users have successfully accessed the network, the enhanced Counting process ends.
- the use of the enhanced Counting mechanism for the triggering of group users may require multiple triggers for a group of users, gradually connecting all or most of the users in the group to the network, and requiring the network to notify the UE when to end the packet trigger.
- the identifier that informs the end of the triggering of the packet may be a special access probability factor, which may be a different session ID, or a special message.
- Figure ⁇ is a schematic flow diagram of a method 70 of RAN triggering access in accordance with one embodiment of the present invention.
- the above enhanced Counting mechanism is adopted, and the access probability factor a in the mechanism is taken as an example of the access parameter.
- the RAN node receives a Session Start Request message from the upstream node, which carries the TMGI of the packet.
- the access probability factor & is calculated.
- the RAN itself saves the UE situation of the packet in the current cell, or may obtain the UE situation of the packet of the current cell from other nodes, the RAN according to the load condition of the current cell and the current cell in the packet in S72 The number of UEs belonging to the TMGI, the probability factor a of the access is calculated, and the UE is notified.
- the RAN does not reserve the UE situation of the packet in the current cell and cannot obtain the packet UE situation of the current cell from other nodes, the RAN sets a smaller probability factor a according to the load condition of the current cell, and Notify the UE. In general, a needs to be set smaller at this time.
- the RAN transmits an enhanced Counting Request message at S73 as an access trigger message of the embodiment of the present invention.
- the message also carries an access probability factor a for the UE to determine whether to access.
- the network For the user who has not successfully accessed after the end of the packet access trigger, the network initiates paging to access or the user initiates an access request.
- the UE determines whether a report notification needs to be performed according to the access parameter. The UE that needs to be reported establishes a connection after the Counting Request message. If the network is successfully accessed, no access is initiated in the subsequent process until the end message is received or the related packet triggering access message is not received any more. If the network is not successfully connected, the MCCH is continuously monitored, and the access parameters are determined according to the access parameters.
- the user who has not received the Counting Request message and the user who has not calculated the access continues to listen to the Counting Request message, and judges whether to report it according to the access parameters.
- the UE may not successfully initiate the access, the UE may The user initiates an access request or waits for a page of the network to initiate an access request.
- the embodiment of the present invention can implement packet trigger access by using the Counting mechanism of the extended MBMS.
- Session Start Request message in addition to the TMGI, some other IDs, such as a Session ID, may be included. At this point, you can use the Session ID to enhance the above scheme.
- the BM-SC may subdivide the previous CN packet (identified by TMGI) according to different Session IDs, and establish a mapping relationship between the Session ID and the access information (such as the access probability factor). In this way, you can use TMGI and Session ID to trigger and control the access of a group of users.
- Session IDs can be utilized to distinguish between different operations of a group of UEs (identified by TMGI). For smart meter reading, different operations such as accessing the network and performing measurements can be performed. The session ID is mapped to different operations and notified to the UE, and the operation of a group of UEs can be controlled by using TMGI and Session ID.
- different session IDs can also be used to control the number of times the user initiates access.
- the UE successfully accesses the network no access is initiated according to the information on the MCCH before the session ID is changed; after the session ID changes, the The packet access process is started, that is, the access trigger message carrying the changed session ID is resent.
- MBMS can also be utilized to perform notification of user group triggering behavior.
- the length of the MCCH message is generally limited, and in many applications, the operation/behavior of the UE may be diverse.
- the extension may be further extended.
- an MTCH message corresponding to the MCCH message may be generated, and the corresponding UE is notified in the corresponding MTCH. To control the operation of the UE.
- the UE After listening to the information transmitted in the MCCH, the UE further listens to the data (MTCH message) transmitted in the MTCH, and further operates according to the MTCH message, such as initiating access, or monitoring data, or performing firmware update, etc. .
- the embodiment of the present invention utilizes TMGI as the M2M to implement packet trigger access in the identity of the CN packet.
- Some embodiments of the present invention can effectively implement packet access triggering of CN and RAN, and can maintain CN and RAN packets according to network conditions.
- the embodiment of the present invention can implement packet triggering access without adding new signaling, has low complexity, and can be compatible with existing systems.
