The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without departing from the inventive scope are the scope of the present invention. FIG. 1 is a flowchart of Embodiment 1 of a paging method according to the present invention. As shown in FIG. 1, the method includes: Step 101: Obtain an identifier of a group to be paged; the group to be paged includes at least two user equipments. The executor of this embodiment may be an MME on the CN side.

 The user equipments to be paged may be multiple, and the user equipments may be grouped according to the service type. For example, user equipments of the same service type are grouped into groups; each group corresponds to an identifier. When the network side sends a page, it is sent simultaneously for the same group of user equipment.

 When paging of a certain group or groups is required, the MME acquires the identifier of the group to be paged.

 Step 102: Send, according to the TA of the group to be paged, a first paging message including an identifier of the group to be paged to the base station corresponding to the TA of the group to be paged, so that the base station that receives the first paging message is according to the first The paging message transmits a second paging message for paging all user equipments of the group to be paged. The TA of the to-be-patented group is the latest TA registered in the TA corresponding to all user equipments in the group to be paged.

 The MME may obtain the TA of the group to be paged according to the identifier of the group to be paged, and the process of obtaining the TA of the group to be paged may be: the MME obtains a list of TAs corresponding to each user equipment in the group to be paged, where The TA list corresponding to each user equipment includes multiple TAs corresponding to each user equipment, and the time that the TAs included in the TA list corresponding to each user equipment are registered is in a sequential order; then the MME obtains the to-be-patched All the user equipments in the group correspond to the same TA in the TA list, and select one of the latest TAs from the same TA. The newly registered TA is the TA of the group to be paged.

 Each eNB may include multiple eNBs. After obtaining the TA of the group to be paged, the MME performs paging in the TA of the group to be paged, that is, sends a paging message to the eNB corresponding to the TA of the group to be paged. That is, the first paging message includes the identifier of the group to be paged.

After receiving the paging message sent by the CN, the eNB sends a page to all the user equipments included in the group to be paged according to the identifier of the group to be paged in the paging message, that is, sends the second paging message. . among them, When the eNB sends the paging, the eNB can directly process all the user equipments included in the paging group, or re-group all the user equipments included in the paging group before performing the group call.

 In the embodiment of the present invention, the MME of the CN side can perform a group call to the grouped user equipment, and when the MME performs group call for all the user equipments in any group to be paged, all the user equipments in the group to be paged are respectively Selecting the same TA in the corresponding TA, and selecting the last registered TA among the same TAs, and then paging in the selected last registered TA, thereby realizing group paging and reducing network load .

 2 is a flowchart of Embodiment 2 of a paging method according to the present invention. As shown in FIG. 2, the method includes: a paging message. The group to be paged includes at least two user equipments.

 The execution body of this embodiment may be an eNB.

 The MME may group the user equipment according to the service type, and perform group call on the grouped user equipment. Each group has an identifier, and each group includes at least two user equipments. When the MME is paging to any group to be paged, the paging message is sent according to the TA of the group to be paged, that is, the first paging message, where the first paging message includes the identifier of the group to be paged.

 The TA of the to-be-patented group is the latest TA that is registered in the TA corresponding to all the user equipments in the group to be paged. For the procedure of the MME obtaining the TA of the group to be paged, refer to step 102 in the embodiment shown in FIG. Description in .

 The MME sends the first paging message, and then the eNB included in the TA of the to-be-patented group can receive the first paging message sent by the MME.

Step 202: Send a second paging message for paging all user equipments of the group to be paged according to the first paging message. After receiving the first paging message, the eNB sends a page to all user equipments included in the group to be paged according to the identifier of the group to be paged in the paging message, that is, sends the second paging message. The eNB may directly process all user equipments included in the paging group, or perform regrouping of all user equipments included in the paging group before performing group paging.

 In the embodiment of the present invention, the eNB receives the group call of the grouped user equipment by the MME on the CN side, and sends a paging to the user equipment to be paged, so that group paging can be implemented, and the network load is reduced.

 FIG. 3 is a flowchart of Embodiment 3 of the paging method of the present invention. The embodiment is based on the embodiment shown in FIG. 1 and FIG. 2. As shown in FIG. 3, the method includes:

 Step 301: The MME obtains an identifier of the group to be paged.

 The CN side groups multiple UEs according to the service type, and assigns an identifier to each group, that is, a group ID (Group ID). Specifically, when any UE accesses the network, the UE reports its corresponding service type. The side allocates a group ID (Group ID) to the UE according to the service type corresponding to the UE, that is, the CN side adds the UE to the corresponding group. The UEs in the same group all correspond to the same identifier.

 When there is a service demand, the MME may perform a group call to the UE, that is, paging any one or more groups of UEs, and any one or more groups of UEs to be paged are the to-be-paged group.

 Step 302: The MME sends, according to the TA of the group to be paged, a first paging message including an identifier of the group to be paged to the base station corresponding to the TA of the group to be paged. The TA of the to-be-patented group is the latest TA registered in the TA corresponding to all UEs in the to-be-patented group.

After the MME obtains the identifier of the group to be paged, the MME of the group to be paged can be obtained. Specifically, the MME can maintain two TA lists at the same time: a TA list of the paging group and a TA list of all UEs in the paging group, where each UE has its own TA list, and each TA list may include multiple TA; the two TA lists have a certain mapping relationship; the mapping relationship may be: Each UE in the paging group The same TA in the TA list constitutes a TA list of the paging group; for example: the paging group includes n UEs, and each TA list of the UE includes multiple TAs, where the TA list of the n UEs If the TA in the public is k TAs (TA1, TA2 TAk), then the TA list of the paging group includes at least the k TAs (TA1, TA2 TAk).

 The time at which the k TAs included in the TA list of the paging group are registered is in a sequential order. When the MME sends a page to the group to be paged, the latest registered TA is obtained from the TA list of the paging group. And then paging according to the latest registered TA, that is, sending a packet paging message to the base station corresponding to the latest registered TA; wherein the latest registered TA is the group to be paged. TA; the packet paging message includes an identifier of the group to be paged.

 Step 303: The eNB receives the first paging message sent by the MME.

 After the MME sends the packet paging message, each base station (eNB) corresponding to the TA of the group to be paged can receive the packet paging message sent by the MME, that is, the first paging message.

 Step 304: The eNB sends, according to the first paging message, a second paging message for paging all UEs in the group to be paged.

 After receiving the paging message sent by the MME, the eNB sends a second paging message to all UEs in the group to be paged according to the identifier of the group to be paged carried in the paging message.

 Specifically, when the eNB sends the second paging message to all the UEs to be grouped, the eNB may not re-group the to-be-patented group, or may re-group the to-be-patched.

 When the eNB does not re-group the group to be paged, the eNB acquires the identifier of the group to be paged from the first paging message, and then carries the identifier of the group to be paged in the second paging message that is sent, that is, the eNB Sending a second paging message for paging all UEs to be paged group including the identity of the group to be paged.

When the eNB re-groups the group to be paged, the eNB acquires the group to be paged according to the identifier of the group to be paged. UE, re-grouping all UEs of the group to be paged, and sending a second paging message for paging all the UEs to be paged group including the re-grouped group identifier; The specific description of the paging group regrouping:

 The eNB obtains the identifier of the group to be paged from the first paging message, and then obtains all the UEs included in the group to be paged according to the identifier of the group to be paged, where the eNB can know the identifier of the paging group in advance. Corresponding relationship of all UEs included in the paging group; afterwards, the eNB may re-group the paging group according to the service type, the load condition of the eNB, and/or the occupancy of the paging resource, for example: a group to be paged may be Re-divided into multiple groups, or a plurality of to-be-patched groups can be combined into one group, and multiple groups to be paged can be re-divided into multiple groups, and the eNB configures group identifiers for each group that is re-divided; The group ID after grouping can be referred to as a RAN group identifier.

 The process for the eNB to re-group the paging group may be, for example, the UE reporting service.

(service), the eNB establishes a context, including RAN side packet information, intra-group terminal ID, and the like; the eNB may carry the RAN Group ID (RAN Group ID) information to the UE through an RRC Connection Reconfiguration (RRC Connection Reconfiguration) message; The packet on the RAN side is controlled by the eNB; the eNB knows the information of all UEs in the group.

 After the eNB re-groups the to-be-patched group, the eNB carries the re-grouped group identifier in the second paging message that is sent, that is, carries the RAN group identifier, and the eNB can locate the resource according to the RAN group identifier and the eNB itself. Occupancy, calculate the sending time of a paging message, that is, calculate PF (Paging

Frame, paging frame) and PO (Paging Occasion, paging sub-frame), then send a second paging message at the calculated PF and PO, the UE can listen to the paging channel in the corresponding PF and PO, if received The paging message sent to itself, the UE performs random access.

Step 305: If the eNB fails to perform paging to the first UE by using the second paging message, the eNB goes to The first UE performs repeated paging.

 The first UE is any one of the groups to be paged. This step is a process in which the eNB performs repeated paging after the paging failure.

 After the eNB sends the second paging message to the UE to be paged, the eNB can check whether the UE in the paging group has responded to check whether the paging is successful. Specifically, the eNB checks the paging within a certain time. Whether the UE in the group responds, and calculates the PF and PO according to the IMSI number of the unresponsive UE, and then classifies the UEs with the same PF and PO into the same unresponsive queue. The eNB can then repeat the single call to the UEs in the unresponsive queue.

 The process by which the eNB performs a repeated single call to the UE in the unresponsive queue may be, for example:

 The eNB allocates paging resources to the UEs in the unresponsive queue, and preferentially ensures that the UEs with higher priority (for example, H2H terminal users) obtain paging resources, and if there are remaining paging resources, allocate the remaining paging resources to the unresponsive Other UEs in the queue use; the principle of allocation may be round-robin allocation; if the remaining resources are sufficient, the UEs in the unresponsive queue will all get resources; if the resources are insufficient, the UEs that are not allocated resources will wait until the next PO allocation ;

 The UE that gets the paging resource will be repeatedly paged and respond to the paging message; if it does not respond again, the unresponsive UE will join the unresponsive queue again, but at this time the UE will be ranked at the end of the unresponsive queue. To ensure that the UE that has not previously allocated paging resources can allocate resources first; in addition, when repeating paging, the timer T1 and the maximum number of repeated single calls N1 can be preset, if T1 does not time out and the maximum repeated single call is not reached. The number of times N1, then the UE that does not respond to the repeated paging will have the opportunity to continue to be paged. If the timer T1 times out or has reached the maximum number of repeated single calls N1, the repeated paging of the unresponsive UE is stopped.

Next, the process of performing repeated paging after the MME fails to send a page is described. Can be pre- The MME sets the timer T2 and the maximum number of repeated single calls N2. If the timer T1 set by the eNB times out or reaches the maximum number of repeated single calls N1, the MME may not respond to the UE in the CN packet before the T2 times out. Repeat the single call until the maximum number of repeated single calls N2 or timer T2 is reached. The following steps 306-step 308 are the process of repeating paging for the MME.

 Step 306: If the paging to the first UE fails by using the first paging message, the MME pages the first UE in the first TA; the first TA is the TA that is newly registered by the first UE.

 After the MME sends the first paging message to the base station corresponding to the TA of the group to be paged, the MME may wait for the response of each UE in the group to be paged before the timer T2, if the timer T2 expires, If the response of the first UE is not received, the MME may perform repeated paging on the first UE. The first UE may be any one of the groups to be paged. In general, if the UE does not respond within the first paging TA, the UE may move to another TA, thereby requiring repeated paging of the UE by other TAs.

 The process of the MME repeating the paging of the first UE is specifically: the MME queries the TA list of the first UE, and then obtains the latest registered TA in the TA list of the first UE, and the newly registered TA is called The first eNB is configured to perform paging on the first UE in the first TA, that is, the MME pages the first UE in the eNB corresponding to the first TA.

 Step 307: If the paging of the first UE fails in the first TA, the first UE is paged in the first TA group; the first TA group includes the TA corresponding to the first UE and the to-be-picked The same TA in the TA corresponding to all UEs in the group.

The MME maintains the TA list of the first UE and the TA list of the to-be-patented group, where the TA list of the to-be-patented group includes the TAs corresponding to all the UEs in the to-be-patented group. For details, refer to the paging group in step 302. The first TA group is described.

 If the MME fails to page the first UE in the first TA in step 306, the MME sends a page to the eNB corresponding to all TAs included in the first TA group to perform repeated paging on the first UE.

 Step 308: If the paging of the first UE fails in the first TA group, the first UE is paged in the second TA group; the TA included in the second TA group is the TA corresponding to the first UE. And the TA included in the second TA group is not the TA that the UEs in the group to be paged in common correspond to.

 Referring to the description in step 307, the TA of the first UE and the same TA in the TA list of the group to be paged constitute the first TA group; then the TA list of the first UE and the TA list of the group to be paged The different TAs constitute the second TA group.

 If the MME fails to page the first UE in the first TA group in step 307, the MME goes to the second.

The eNB corresponding to all TAs included in the TA group sends a page to perform repeated paging on the first UE.

 It should be noted that the MME and the eNB may check whether the UEs in the packet have responded in a predetermined time range, wherein the predetermined time may be determined by the MME and the eNB, respectively.

 In this embodiment, based on the CN side packet paging, the packet paging on the RAN side is added, and the paging can be further performed on the CN side and the RAN side.

 It should be noted that, in another paging mode, only the RAN side can group paging, and

The RAN side implements the repeated paging, that is, the eNB groups the UEs corresponding to the multiple paging messages sent by the MME, and then performs the group paging and the repeated paging. The process of the eNB performing the grouping and repeating paging on the UE can be found in step 304. And the description in step 305.

 In this embodiment, except that the MME on the CN side can perform group group calling on the UE to reduce the network load,

The repeated single call on the RAN side can ensure that the UE that has not successfully accessed the network due to congestion can have the opportunity to receive the paging message again, and increase the chance of the UE successfully accessing the network. When the UE is the MTC-UE, these have The low mobility MTC-UE can access the network after repeating the single call on the RAN side; and when the RAN side repeats the single call, the unresponsive UE cyclically occupies the paging resource, and can ensure that the unresponsive UE repeats paging. When there is a timeout for the paging group message, the UE that can ensure that the secondary paging is not responded can receive the paging message again, thereby increasing the chance of the UE successfully accessing the network. Furthermore, for the UE that has not responded after repeating the single call on the RAN side, the MME may repeat the single call according to different TAs, thereby increasing the chance of the UE successfully accessing the network.
