Description

Paging and control method and device thereof

This application claims the priority of the Chinese Patent Application filed on January 11, 2016, the Chinese Patent Application No. 201610015649.X, the application entitled "Paging and its Control Method and Apparatus", the entire contents of which are incorporated by reference. Combined in this application.

Technical field

The present application relates to the field of communications technologies, and in particular, to a paging and control method and apparatus therefor.

Background technique

In existing mobile communication systems, repeated transmission of pages is controlled by the core network. However, in the system research of NB IoT (Narrow Band Internet of Things), in the case of long discontinuous reception (long DRX), in the case where repeated paging messages need to be sent, paging related The storage time of the information in the core network is very long, which increases the storage load of the core network. And if each retransmission, the paging message is repeatedly sent from the core network to the base station, which undoubtedly increases the transmission load on the network interface. For the NB-IoT system, the terminals of the NB-IoT are mostly low-cost terminals, and the probability of one reception success is lower than that of the ordinary terminal. For the coverage enhanced terminal, the paging message is not within the maximum CE range. Sending may also cause the terminal to fail to receive the paging message.

About MTC (Machine Type Communication), the following is introduced:

As a new communication concept, MTC aims to integrate many different types of communication technologies, such as machine-to-machine communication, machine control communication, human-computer interaction communication, and mobile internet communication, thereby promoting social production and lifestyle. development of. It is expected that the business of human-to-human communication in the future may only account for 1/3 of the entire terminal market, and a larger amount of communication is the inter-machine (small bandwidth system) communication service.

Current mobile communication networks are designed for communication between people, such as the determination of network capacity. If you want to use mobile communication networks to support small-bandwidth system communication, you need to optimize the mechanism of the mobile communication system according to the characteristics of small-bandwidth system communication, so that when traditional human-to-human communication is not affected or less affected. To better achieve small bandwidth system communication.

The coverage enhancements are as follows:

In existing networks, operators find terminals that work in some scenarios, such as terminals working in basements, shopping malls, or building corners. Because wireless signals are severely blocked, signals are greatly attenuated and cannot communicate with the network. The deep coverage of the network in these scenarios will greatly increase the network construction cost. After testing, it is considered that there is a need to enhance the existing coverage to a certain extent. Achieve coverage enhancement, a more feasible method is to need existing channels With repeated transmission or the like, it is theoretically possible to obtain a certain degree of coverage gain by performing tens to hundreds of repeated transmissions on an existing physical channel.

The introduction to the paging mechanism is as follows:

From the perspective of the wireless network, in the LTE (Long Term Evolution) system, the UE (User Equipment) has two states, namely, a connected (RRC_connected) state and an idle (RRC-idle) state. The UE can only send uplink data when it enters the RRC_connected state. After the data is transmitted by the UE, the network monitoring terminal uses the Radio Resource Control (RRC) connection of the terminal through the RRC (connection release) message to enable the UE to enter the RRC_idle state.

The main job of the UE in the RRC_idle state is to listen to the paging on the network side. In order to save power, the paging is monitored in a discontinuous reception (DRX) manner. That is, only a short period of time in each cycle is in the receiving state, and other times in the cycle are in the non-receiving state. For the LTE system, the maximum DRX period configured on the network side is 2560 ms. For LTE and NB IOT systems that support eDRX, the DRX cycle can be configured for up to tens of minutes. In the case where the DRX cycle is configured, only the receiver is turned on to receive the network side paging indication message and the possible paging message, and the receiver is turned off at other times. In this way, the purpose of power saving can be achieved. Only one subframe (1ms) in each paging cycle is in the receiving state, and other times in the cycle are non-receiving, as shown in FIG.

Referring to FIG. 2, for the paging process, paging is initiated by the core network entity, and the paging message is first sent to the evolved base station (eNB). The paging message carries a UE-specific DRX configuration. For the LTE system, the eNB will compare the DRX cycle and the DRX cycle configured in the system message, and use the shorter DRX cycle to send the paging message. According to the specification of 36.413, it can be seen that the paging message sent from the mobility management entity (MME) of the core network side to the eNB carries the contents as shown in Tables 1 and 2 below:

Table I

Table II

It can be seen that the paging DRX in the paging message determines the paging period, and the TAI (Tracking Area Identity) list (list) gives the range of paging message transmission. The retransmission of the paging message is controlled by the core network.

In summary, as the length of eDRX increases, it can be extended to several tens of minutes, while the retransmission control of paging messages in the existing system is controlled by the core network (CN), and the UE for the NB IOT system. Most of the UEs that are not mobile, or UEs that are mobile in a small range. If the UE retransmits the paging to the core network, the paging network may store too much information related to the core network. Excessive storage space. And if the paging message is retransmitted by the core network, all the information in the entire PAGING message is retransmitted, which undoubtedly increases the transmission load on the interface. In addition, if the base station is allowed to perform an automatic retransmission paging message, that is, the base station itself decides whether to retransmit the paging message and retransmit the paging message, and the core network cannot know whether the base station is still retransmitting the paging message or has terminated the heavy The paging message is sent, and if the core network receives the paging response message of the UE, the base station still retransmits the paging message to the UE, which also causes waste of resources.

detailed description

Referring to FIG. 3, on the core network side, a paging control method provided by an embodiment of the present application includes:

S101. Determine that paging of the user equipment UE is required, and that the base station needs to control paging retransmission;

S102. Send a paging message to the base station, where the indication information of the number of paging retransmissions is carried.

Optionally, it is determined that paging of the UE is required by receiving a paging message from the UE. That is, when the core network receives the paging message of the UE, it determines whether the eNB is allowed to control the paging retransmission. If necessary, when the PAGING message is sent to the base station, the retransmission number information is carried, and a timer is started at the same time. The timer duration of the timer is greater than or equal to the time required for the base station to complete all times of retransmission of the paging message, that is, the timer will expire after the base station transmits all the repeated pages.

After the base station receives the PAGING message, if the number of retransmissions is carried in the PAGING message, the base station starts a paging counter, and controls the number of times the paging message is sent according to the requirement of the number of retransmissions.

If the core network receives the paging response of the UE when the timer expires, it indicates that the paging response message of the UE is received when the number of retransmissions of the base station does not reach the maximum number of times, and the core network may send a paging termination message to the base station, so that The base station terminates the relevant paging.

Further, the paging termination message sent by the core network to the base station may carry the identifiers of the multiple UEs to indicate that the base station stops paging for multiple UEs at the same time, so as to prevent the base station from repeatedly transmitting the paging message that has been responded to. The resulting resources are wasted.

The UE is a fixed terminal or a low mobility terminal based on the attributes of the UE; or the UE is a machine type communication MTC terminal or a NB IoT terminal with low mobility;

The TA (Tracking Area) in the TAI list belongs to the coverage of the same base station according to the range list of the TAI (Tracking Area Identity) list (list) carried in the paging message of the UE.

Correspondingly, on the access network side, for example, on the base station side, referring to FIG. 4, a paging method provided by the embodiment of the present application includes:

S201. Receive a paging message sent by the core network that needs to page the user equipment UE.

S202. If the paging message carries the indication information of the number of paging retransmissions, the paging message is repeatedly sent to the UE according to the indication information.

After receiving the paging termination message sent by the core network, the base station terminates the related transmission of the related paging message, and clears the related content of the corresponding paging message.

Example 1:

When there is a paging message to be sent, the MME learns from other servers or application servers of the core network that the paging terminal is a low mobility terminal, or the MME determines that the UE is under the coverage of one eNB according to the range of the TAI list, and then sends When the eNB is PAGING message, the paging (PAGING) message carries the number of repetitions of the paging (assumed to be n). After receiving the base station, the base station determines the timing of the paging of the paging UE according to the content in the PAGING message, and performs paging transmission. The base station will send a paging message on the paging position monitored by the UE in consecutive n DRX cycles.

The content carried by the paging message on the S1 interface provided in the embodiment of the present application is as follows:

Table 3

It can be seen that the last row of the third row carries the paging repetition number (Paging repetition number) in the paging message to indicate the number of times the base station repeatedly sends the paging message.

Example 2:

After the core network sends the paging message to the eNB and carries the number of repetitions, a timer T can be started, and the size of the T is greater than the length of the n*DRX period. When the timer expires and the CN does not receive the paging response, the CN can select Discard or try to re-paging on a larger scale. If the timer does not time out, the CN receives the paging response message, and the CN may generate a new paging termination message to the eNB to inform the eNB to terminate the paging.

The content of the paging termination message is as shown in Table 4 below:

参数名称parameter name	是否必须出现Whether it must appear
Message Type(消息类型)Message Type	MM
UE Identity Index value(UE标识索引值)UE Identity Index value	MM

Table 4

It can be seen that the message type and the UE identity index value may be carried in the paging termination message to indicate that the base station terminates paging for the UE.

After receiving the paging termination message, the base station terminates the paging related UE and deletes the paging information of the related UE.

Further, in order to save signaling, the paging termination message sent by the core network to the base station may provide an identifier index value of multiple UEs, and may terminate paging of multiple UEs together.

Example 3:

When the base station receives the indication information that the number of paging retransmissions is carried in the PAGING message sent from the core network, the base station needs to send the paging message before the paging termination message is received or the number of paging retransmissions reaches the upper limit. For a coverage enhanced terminal, the base station can decide the manner in which the paging message is sent according to the level of its coverage enhancement. If not received in time To the paging response, the base station can choose to make the following attempts during retransmission:

The base station adjusts the level of coverage enhancement, and gradually increases the level, that is, attempts to send a paging message within a larger coverage enhancement range;

Alternatively, the base station may send the paging message according to the coverage enhancement level of the terminal when transmitting the paging message for the first time, and send the paging message within the maximum coverage enhancement range when the paging message is repeatedly sent.

Example 4:

Referring to FIG. 5, the process of performing paging in the entire network mainly includes:

The S-GW (Serving Gateway) sends a paging request to the MME;

After receiving the paging request sent by the S-GW, the MME determines that the base station needs to perform paging retransmission for the UE, and sends a paging message to the eNB, where the number of paging message retransmissions is carried, and a timer is started;

After receiving the paging message, the eNB finds that the number of retransmissions of the paging message is carried, and repeatedly sends the paging to the UE according to the number of retransmissions;

After the UE receives the paging, if it accesses the network and responds to the paging, that is, the UE receives the paging message and responds, it is marked with "normal condition". After receiving the paging response, the MME of the core network may send a paging termination message to the base station if the timer is not timed out, and if the base station needs to send the repeated paging message to the UE, the MME may immediately terminate the UE. Transfer paging messages.

The length of the timer started by the core network is related to the number of times the paging message sent by the base station is repeatedly sent. The timer should be timed out after the maximum number of times the base station repeatedly sends the paging message. If the timer expires, the core network does not need to notify the base station to stop paging.
