detailed description

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 obvious that the described embodiments are only a part of the embodiments of the present invention, but not all 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 schematic diagram of a paging method according to an embodiment of the present invention. The method shown in FIG. 1 can be used by a terminal (also referred to as user equipment, UE), an evolved NodeB (eNB), a mobility management entity (MME), a serving gateway (S-serving gateway, S- The interaction between the GW) and the packet data network gateway (PDN GW) enables accurate paging of the UE.

For example, the radio link is released shortly after the end of the data service transmission, and the UE enters an idle state. When the network side needs to send downlink data or downlink signaling to the UE in the idle state, the paging process is triggered. As shown in Figure 1, the method includes:

S101. The PDN GW sends downlink data to the S-GW.

S102. After the downlink data reaches the S-GW, the S-GW sends a downlink data notification message to the MME. For example, the downlink data notification message may carry information indicating the UE user type and/or information indicating the service type of the downlink data service. The user type information of the UE includes, but is not limited to, an international mobile subscription identity (IMSI) or a mobile station international ISDN number (MSISDN). The service type information of the data service includes but is not limited to an access point name (APN), a QoS class identifier (QCI), an address resolution protocol (ARP), or a circuit domain exchange fallback ( Circuit switched fallback, CSFB).

S103: After receiving the downlink data notification message sent by the S-GW, the MME sends a downlink data notification ack message to the SGW.

S104. The MME determines a paging rule for the paging.

Specifically, the MME first determines the paging policy of the current paging according to the user type information. Paging strategies include, but are not limited to, standard paging or precision paging. For example, when the user type information indicates that the UE belongs to a VIP user, standard paging is adopted, otherwise, accurate paging is adopted. When the paging uses the standard paging, the MME sends paging signaling to all eNBs in the TA List where the UE is located according to the information of the UE in the downlink data notification message.

If the MME determines that the paging uses accurate paging according to the user type information, the MME obtains the paging rule of the accurate paging according to the service type information. The paging rule is used to indicate the initial paging range of the paging UE. The initial paging range includes the following granularity: the last base station (last eNB) where the UE camps, the last base station where the UE camps, and its neighboring base stations (last eNBs, last eNBs), the UE station. The last TA (eNBs in last TA, referred to as last TA) and the TA list (eNBs in last TA List, referred to as last TA list) where the last TA of the UE resides.

For example, if the service type information indicates that the data service is a browse web service, the initial paging range is set to be the last eNB; and the service type information indicates that the data service is the LTE network. For voice over LTE (VoLTE) services, set the initial paging range to last TA. The above are examples and are not intended to be limiting.

After the MME determines the paging rule for the paging, that is, after determining the initial paging range, the MME adjusts the paging rule according to the reference time in which the UE resides in the current region and the actual time in which the UE resides in the current region.

For example, the reference time for camping on the current region includes a reference time to camp on the current eNB and/or a reference time to camp on the current TA; the actual time to camp on the current region includes the actual time and/or resident of the current eNB camping on The actual time of the current TA. The comparison result of the MME according to the reference time of camping the current eNB and the actual time of camping on the current eNB, and/or the comparison result of the reference time of the current TA and the actual time of camping on the current TA, to last eNB->last The order of the eNBs->last TA->last TA List filters the paging rules, that is, the MME gradually expands the initial paging range according to this, thereby obtaining the adjusted initial paging range, as shown in FIG. 2. The ranges in Figure 2 are last eNB, last eNBs, last TA, and last TA List, respectively.

In the present invention, for example, in S100, the MME needs to configure different reference times for each area in advance. That is to say, the MME needs to set different reference times for different areas of different locations in advance, as shown in Table 1.

Table 1

As shown in Table 1, the MMEs in the MME configure different reference times for eNBs in different areas in advance, and configure different reference times for TAs in different areas. Configuring different reference times for eNBs of different regions may be pre-stored in the MME in the form of a table. How the MME configures reference times for different regions will be further described in conjunction with Figures 2 through 5D.

The following description will be exemplified in conjunction with FIG. 2 and Table 1. Assume that the actual time that the UE of this paging resides in the current eNB is 400s, and the actual time of the current TA is 950s.

The MME may determine, according to the downlink data notification message, the location of the eNB involved in the paging, and then determine the reference time of camping the eNB and the reference time of the resident TA by means of table lookup. For example, when the eNB is within one ring, the reference time for camping on the eNB and the reference time for camping TA are 580s and 900s, respectively. Since the actual time that the UE camps on the current eNB is less than the reference time for camping on the eNB, and the actual time of camping on the current TA is less than the reference time for camping the TA, indicating that the UE may not be under the coverage of the eNB, but Still under the TA coverage. Therefore, the MME will skip the paging range of "last eNB" in the paging rule and jump directly to start paging from the next level "last eNBs".

Optionally, the MME further compares the absolute values of the following two differences: a reference time of camping the eNB and a difference between the actual time of the current eNB, and a reference time and resident of the TA. The difference in the actual time of the current TA. Jump if the absolute value of the difference between the reference time of the eNB and the actual time of the current eNB is greater than the absolute value of the difference between the reference time of the TA and the actual time of the current TA To start paging from "last eNBs". If the absolute value of the difference between the reference time of the eNB and the actual time of the current eNB is less than the absolute value of the difference between the reference time of the TA and the actual time of the current TA, then skip further. The paging range of last eNBs" jumps directly to the paging starting from the next level "last TA". For example, when the eNB of the current paging is within one ring, the MME may directly page the UE from the range of the last TA, if the UE is not paged within the range of the last TA, and then in the range of the last TA list The UE is paged internally, that is, the UE is accurately paged in the order of last TA->last TA List.

When the eNB of this paging is within the second ring of the ring, the reference time of camping on the eNB and the reference time of the resident TA are 460s and 700s, respectively. Similarly, the MME can directly page the UE from the range of the last eNBs. If the UE is not paged within the range of the last eNBs, the UE is paged within the range of the last TA. If the UE is not paged in the range of the last TA, the UE is paged within the range of the last TA list, that is, the UE is accurately paged in the order of last eNBs->last TA->last TA List.

When the eNB of this paging is outside the second ring (for example, a suburb), the reference time for camping on the eNB and the reference time for camping TA are 190s and 450s, respectively. Due to UE resident The actual time of the current eNB is greater than the reference time for camping on the eNB, indicating that the UE is still under the coverage of the eNB. Therefore, the MME performs accurate paging on the UE in the order of last eNB->last eNBs->last TA->last TA List.

S105. The MME initiates paging to the UE according to the determined paging policy.

Therefore, since the MME determines different reference times for each base station/TA to camp, the number of eNBs involved in paging can be accurately controlled, and the paging load is reduced. For example, there is an MME in the existing network with both urban and suburban areas. In order to reduce the paging delay, the initial paging range is large in the urban area; in order to reduce the number of paging signaling in the suburb without affecting the delay, the initial paging range is small. In the prior art, if a unified paging configuration is adopted, the urban area or the suburb will be affected, and the best effect of accurate paging cannot be achieved. In the present invention, the MME configures a separate paging policy for each UE on each eNB, thereby achieving a smaller paging delay and less signaling, thereby reducing the paging load and saving network resources. .

FIG. 3 is a flowchart of a paging method according to an embodiment of the present invention. The flow in FIG. 3 is performed by the MME side. Figure 3 will be described in conjunction with Figures 1 and 2.

S301. The MME obtains a paging rule for paging the UE according to the service type of the data service. The paging rule is used to indicate the initial paging range for paging the UE.

S302. The MME acquires a reference time that the UE resides in the current area. The reference time for the UE to camp on each different area is different.

Optionally, the MME may obtain a reference time for the UE to camp on the current eNB and/or a reference time for camping on the current TA. For example, the eNB has the coordinate information (eNB coordinates) of the eNB, that is, the latitude and longitude information, and the eNB can report the coordinate information of the eNB to the MME in multiple manners. How the eNB reports its coordinate information to the MME will be further described in conjunction with Figures 5A-5D. The MME determines the coverage of each eNB according to the coordinate information reported by the eNB, so as to determine the reference time for the UE to camp on the current eNB and/or the reference time for camping on the current TA according to the coverage of each eNB. For example, the MME may first form a virtual map according to the coordinate information reported by the eNB. The virtual map is composed of all eNB coordinate information under the MME. For an eNB, its coordinates and the distance from the surrounding eNBs can be obtained therefrom to determine the coverage of each eNB. For example, the virtual map can be saved in the form of a table in the MME. Therefore, the MME may determine the coverage of each eNB according to the location of each eNB in the virtual map, and determine a different reference time of the current eNB for each eNB according to the coverage of each eNB. And/or the reference time of the current TA. For example, the MME may determine different reference times by counting the UE camp time reported in the coverage within a certain period of time.

S303. The MME adjusts the paging rule according to the reference time and the actual time that the UE camps on the current area. For details on how the MME adjusts the paging rule, refer to the description of S104, and details are not described herein again.

Optionally, the MME may determine, by using the following manner, the actual time that the UE in the idle state camps on the current eNB: when performing the tracking area update (TAU) process, the eNB sends a TAU request message to the MME, where the request message is sent. The information that the UE can carry the cell reselection. The MME calculates a time difference between the UE performing cell reselection twice according to the information of the UE cell reselection in the TAU request message, and uses the time difference as the actual time that the UE camps on the current eNB.

S304. The MME pages the UE according to the adjusted paging rule.

FIG. 4 is a flowchart of a paging method according to an embodiment of the present invention. The flow in FIG. 4 is performed by the eNB side. Figure 4 will be described in conjunction with Figures 1 through 3.

S401, the eNB reports the coordinate information of the eNB to the MME, so that the MME determines different camping reference times for each eNB according to the coordinate information reported by each eNB, and determines a paging rule for accurate paging according to different camping reference times. . How the eNB reports its coordinate information to the MME will be further described in conjunction with Figures 5A-5D.

S402. The eNB receives a paging message sent by the MME, where the paging message is sent by the MME to the eNB according to the paging rule.

5A to 5D show an example in which four types of eNBs report coordinate information to an MME. The process in Figure 5A applies to the S1 setup process. When the eNB is reset or powered up, The eNB will perform the S1 setup process. The eNB carries the coordinate information of the eNB to the MME by carrying the coordinate information of the eNB (as shown in FIG. 5A) in the S1 setup request message sent to the MME. After receiving the S1 setup request message, the MME returns an S1 setup response message to the eNB.

The flow in FIG. 5B to FIG. 5D is applicable to a process of handing over a UE from a source eNB to a target eNB. 5B and FIG. 5C are applicable to the X2 port-based handover procedure, and FIG. 5D is applicable to the S1 port-based handover procedure. More specifically, FIG. 5B is applicable to an X2-port based handover procedure of a serving gateway (S-GW) change, and FIG. 5C is applicable to an S2-GW unchanged X2-port based handover procedure.

In FIG. 5B and FIG. 5C, after the handover is performed between the source eNB and the target eNB, the target eNB sends a path switch request message to the MME, where the path switch request carries the coordinate information of the target eNB. The MME thus receives the coordinate information reported by the eNB.

In FIG. 5D, before the handover is performed between the source eNB and the target eNB, the source eNB sends a handover request message to the source MME, where the handover request message carries coordinate information of the source eNB. The MME thus receives the coordinate information reported by the eNB.
