Description

Method for paging terminal in idle mode, advanced network element device and system

Technical field

The present invention relates to the field of communications, and in particular to a method for paging a terminal in an idle mode, an advanced network element device and a system.

Background technique

In a wireless communication system, a base station (Base Station, BS for short) is used to provide wireless coverage within a certain geographical range by using a designated wireless channel. This geographical range is called a cell. Usually, in theory, the base station is located in the center of the cell. According to the size of the coverage, the base station can be divided into a macro base station (Macs), a micro base station (PICO BS), and a pico base station (FEMTOCELL BS). Furthermore, in order to extend coverage or expand capacity, one or more relay stations can be placed between the mobile station and the base station. For a mobile station, a relay station is equivalent to a base station. When a mobile station moves from one cell to another, in order to maintain communication, a handover is required.

According to the supported communication protocols, the base station/relay station can be divided into an advanced control station and a conventional control station, and the advanced control station refers to an Advanced Base Station/Advanced Relay Station (ABS/ARS) supporting the advanced communication protocol. The traditional control station refers to a Yardstick Base Station/Yardstick Relay Station (YBS/YRS for short) that can support the traditional communication protocol. In the technology considering compatibility, for the advanced control station, its frame is divided into a first area and a second area. The second area can support traditional communication protocols, so it can be called a traditional area. The first area can only support advanced communication protocols, so it can also be called an advanced area. Similarly, for a mobile station, it can also be divided into an Advanced Mobile Station (AMS) and a Yardstick Mobile Station (YMS). The advanced mobile station can work in the first area or the second area. , while traditional mobile stations can only work in the second area. For a traditional mobile station, the second area of the advanced control station is equivalent to a conventional control station. In addition, when an advanced mobile station accesses a conventional control station, the advanced mobile station is a conventional mobile station for a conventional control station. In addition, the advanced control station can only support advanced communication protocols. At this time, the advanced control station can only have the first area.

The IEEE 802.16 standard is taken as an example for further description. The IEEE 802.16 standard is targeted at An advanced air interface standard proposed by the microwave band, which defines specifications for the physical layer (PHY) and the medium access control layer (MAC). IEEE802.16m, which includes a relay structure, is the most advanced standard technology in the IEEE802.16 standard. IEEE802.16m (hereinafter referred to as 16m) is based on IEEE802.16e (hereinafter referred to as 16e) and IEEE802.16j (hereinafter referred to as 16j). Based on the standard.

Based on the above description, the advanced control station (base station rushing station supporting 16m protocol) can be compatible with supporting traditional mobile stations (mobile stations supporting 16e protocol). Similarly, advanced mobile stations (mobile stations supporting 16m protocol) should also be able to connect. Into the traditional control station (support 16e base station or 16j support station). The first area (also known as the advanced area, 16m zone, referred to as MZone) supports the advanced communication protocol defined by 16m, and the second area (also known as Legacy Zone, LZone for short) can support the 16e/16j protocol. . In addition, the advanced control station can also only have MZone.

In general, when a control station in a system evolves from a legacy control station to an advanced control station, the network to which the control station is connected (also known as the access service network, ASN) will evolve from the traditional network. To the advanced network. However, in the actual system, since the development speed of the control station and the network is not necessarily synchronized, or the market development requires the use of advanced technology as soon as possible, the control station is an advanced control station, and the access service network is a traditional network. , As shown in Figure 1. At this time, if the advanced communication protocol is directly used in the air interface of the advanced terminal and the advanced control station without any change, it is possible that problems occur in subsequent communication with the conventional network.

For example, in order to save power, a mobile terminal (also referred to as a terminal, a mobile station) can enter an idle (Idle) mode, after which the mobile terminal periodically receives downlink broadcast data at discrete intervals and moves between multiple control stations. In the case, the location information is updated to the control station only when needed, without switching and network re-entry. Traditional control stations/terminals and advanced control stations/terminals have large differences in the processing of Idle mode. Taking the 16e and 16m standards as an example, the processing method of paging monitoring of mobile terminals is completely different in the two standards. The paging period (Paging Cycle) and paging shift (Paging Offset) allocated to the mobile terminal by the control station supporting the 16e protocol are all in units of frames, and the paging period allocated by the control station supporting the 16m protocol to the mobile terminal and the seek The call displacement is in superframes, and a superframe usually contains 4 frames. In the case where the control station is connected to a legacy gateway, the paging controller allocates a paging cycle and a paging shift in units of frames for the mobile terminal within its service range, whether it is a 16e or 16m control station, so Advanced control station in a region and mobile The terminal needs to complete the matching mapping of the paging parameters. In addition, in the 16m protocol, the mobile terminal finds a specific frame in the paging monitoring start superframe according to the indication in the paging group identification message (PGID-Info) sent by the control station and the allocated deregistration identifier. In the case where the control station is connected to a legacy gateway, the legacy gateway may not be able to assign a deregistration identifier to the mobile terminal. There are many similar problems, and new methods are needed to solve them.

The following describes the specific process of the above system for paging the terminal in the idle mode in combination with the specific application scenario.

Example 1

In this embodiment, the terminal accesses the first area of the advanced control station (ie, the advanced network element device), and the advanced control station is an advanced control station that only includes the first area, or both the first area and the second The area's advanced control station, and the advanced control station is connected to the traditional access network. In this embodiment, when the terminal accesses or re-accesses the advanced control station, the advanced control station and the terminal determine to use the registration identifier as the paging identifier, and the paging group information message indicates the time domain hash parameter. The following describes the specific process of the advanced control station to implement paging for the idle mode terminal in this scenario. The process is as shown in Figure 2, including the following steps:

Step 200: The terminal enters an idle mode, and the advanced control station interacts with the paging controller to obtain a paging group identifier, a paging controller identifier, a paging cycle, and a paging shift allocated to the terminal. And then sending a deregistration response message including a deregistration identifier, a paging group identifier, a paging controller identifier, a paging cycle, and a paging offset to the terminal to notify the terminal to enter an idle mode, where, to register The paging cycle and the paging displacement in the response message are all in units of frames;

In this step, since the advanced control station is connected to the traditional access network, the paging cycle allocated by the paging controller for the terminal and the paging displacement are counted by the frame of the traditional network, and the advanced control station registers the response. The message also carries the paging cycle and paging shift in units of frames to the terminal. Since in the present embodiment, the advanced control station and the terminal previously determine to use the registration identifier as the paging identifier at the time of negotiation, the advanced control station generates a deregistration identifier (DID) and deregisters the response message (AAI- DREG-RSP) sends information such as paging group identifier, paging controller identifier, paging cycle, paging offset, and deregistration identifier to the terminal.

Wherein, the terminal enters the idle mode, and the terminal actively sends a deregistration request message (AAI_DREG-REQ) to the advanced control station to request to enter the idle mode, or the advanced control station wants the terminal to enter the idle mode;

For example, because there is no data transmission requirement temporarily, when the terminal actively wants to enter the idle mode, the terminal actively sends a registration request message to the advanced control station, requesting to enter the idle mode, as shown in FIG. 4, after receiving the deregistration request, the advanced control station receives the deregistration request. Interacting with the paging controller to obtain parameters such as a paging group identifier, a paging controller identifier, a paging cycle, and a paging shift allocated to the terminal, and sending the acquired information to the terminal by using a registration response message ;

For another example, if the advanced control station wants the terminal to enter the idle mode, the advanced control station may actively assign the paging group identifier to the paging controller, the paging controller identifier, the paging cycle, and the paging displacement. And then actively sending a deregistration response message including the above information to the terminal to request the terminal to enter the idle mode, as shown in FIG. 5.

Step 201: When the network side wants to page the terminal in the idle mode, the advanced control station determines the superframe number used for the paging terminal according to the paging cycle and the paging displacement allocated to the terminal in the frame counting unit;

In this step, if the advanced control station receives the paging notification message of the paging controller, the advanced control station determines the paging period for the paging terminal according to the paging cycle of the paged terminal and the paging displacement of the paged terminal. Superframe, specifically calculating the superframe number of the paging terminal according to the following formula: N sup erframe = floor of[(paging cycle * n + paging offset) I q];

n = [floor of[(Nc rrent _ sup erframe * q - paging offset) I paging cycle] + ljmod {ce/7

In the above formula, N sup erframe represents the superframe number of the paging terminal;

The paging cycle indicates a paging cycle in units of frames;

Paging offset indicates a paging shift in units of frames;

Ncurrent _ sup erframe table The current super middle nickname;

Indicates the number of bits allocated for the superframe number. The number of bits currently allocated for the superframe number is generally q. The number of frames included in the superframe. The current superframe contains 4 frames.

Step 202: The advanced control station determines, according to the paging identifier (in this embodiment, the deregistration identifier) and the time domain hash parameter, a specific frame number for sending the paging broadcast message in the superframe for paging the terminal;

In this embodiment, the advanced control station and the terminal determine that the paging group information message indicates the time domain hash parameter before the negotiation, and the advanced control station registers according to the time domain hash parameter m corresponding to the paging group where the terminal is located and the terminal. The identifier, the frame number at which the paging broadcast message containing the terminal information is transmitted is calculated by the following formula:

Npaging _ frame = DID mod m;

In the above formula, Nlpaging_frame represents a frame number used to carry the paging broadcast message; DID represents a deregistration identifier;

w represents the time domain hash parameter.

A page broadcast message containing the paged terminal information is sent.

The process of implementing the paging on the terminal side is as shown in FIG. 3, and includes the following steps: Step 300: The terminal receives a deregistration response message, obtains a paging cycle in units of frames, and paging displacement information, and according to the acquired paging The period and the paging displacement information calculate the superframe number (Nnext-listening-superframe) that enters the paging listening interval, and the calculation can use the formula below: N sup erframe = floor of[(paging cycle * n + paging offset) I q];

n = [floor of[(Nc rrent _ sup erframe * q - paging offset) I paging cycle] + ljmod

{ce/7

The paging cycle indicates a paging cycle in units of frames;

Paging offset indicates a paging shift in units of frames;

Ncurrent _ sup erframe table The current super middle nickname;

Indicates the number of bits allocated for the superframe number. The number of bits currently allocated for the superframe number is generally

12;

q indicates the number of frames included in the superframe. Currently, the superframe contains 4 frames.

Step 301: After the terminal calculates the paging monitor superframe number, the terminal enters the idle state of the idle mode, until the advanced control station sends the same superframe as the paging monitor superframe number, and the terminal enters the paging listening interval. The length of the paging listening interval is the duration of one superframe (generally the length of 4 frames); Step 302: The terminal parses the time domain hash in the paging group information message included in the first frame from the monitored superframe. The parameter m, and the frame number of the paging broadcast message that the terminal needs to parse is calculated; in this embodiment, the advanced control station and the terminal determine that the paging group information message indicates the time domain hash parameter before the negotiation, so the terminal learns from The time domain hash parameter m in the paging group information message included in the first frame is parsed in the monitored superframe; the frame number of the paging broadcast message that the terminal needs to parse is calculated by using the following formula:

Nlistening _ frame = DID mod m;

In the above formula, Nlistening_frame represents a frame number used to carry the paging broadcast message;

The DID indicates the registration ID.

Step 303: The terminal parses the paging broadcast message included in the corresponding frame according to the calculated frame number, and then determines whether the received paging broadcast message includes a deregistration identifier that matches the self, that is, whether the terminal is paged. . If the terminal is paged (ie, the paging broadcast message includes a de-registration identifier matching with itself), the terminal performs a location update or a network re-entry operation according to the indication in the paging message. Otherwise, proceed to the next monitor; When the terminal performs location update or network reentry, the paging request message and the paging interval included in the ranging response message and the paging displacement should also be in the frame of the traditional network, and further, The number of bits occupied by the paging request message and the paging displacement in the ranging request message and the ranging response message is the same as the number of bits occupied by the paging cycle and the paging displacement in the conventional art. If the terminal is not paged, the terminal calculates the superframe number entering the paging listening interval and enters the paging unreachable state. In addition, when the terminal has data to be sent, the terminal can perform network re-entry at any time and end the idle mode in advance.

Example 2

In this embodiment, it is basically the same as Embodiment 1, except that when the terminal accesses or re-accesses the advanced control station, the advanced control station and the terminal determine to use the traditional identifier, that is, the MAC address hash, as the paging identifier. And the paging group information message indicates a time domain hash parameter. In this scenario, the operation of the advanced control station is the same as that of the advanced control station in Embodiment 1, the main difference is that the advanced control station does not need to carry the registration identifier in the deregistration response message sent to the terminal, and is looking for In the process of calling the terminal, the advanced control station calculates the paging including the terminal information according to the time domain hash parameter m corresponding to the paging group where the paged terminal is located and the MAC address hash (ie, paging identification information) of the paged terminal. The frame number of the broadcast message is specifically calculated by the following formula: The frame number of the paging broadcast message containing the terminal information is calculated:

Npaging _ frame = MAC address hash mod m;

The MAC address hash indicates a MAC address hash;

Represents a time domain hash parameter.

In this embodiment, the operation on the terminal side is also basically the same as the operation in Embodiment 1, except that the terminal parses the time domain hash in the paging group information message included in the first frame in the superframe of the paging terminal. After the parameter m, calculate the frame number of the paging broadcast message that the terminal needs to parse by the following formula:

Npaging _ frame = MAC address hash mod m;

In the above formula, Npaging_frame indicates a frame number used to carry the paging broadcast message; MAC address hash indicates a MAC address hash; Represents a time domain hash parameter.

Example 3

In this embodiment, the terminal accesses the first area of the advanced control station, which is an advanced control station containing only the first area, or an advanced control station that includes both the first area and the second area, and The advanced control station is connected to a traditional access network. In this embodiment, when the terminal accesses or re-accesses the advanced control station, the advanced control station and the terminal determine not to indicate the time domain hash parameter by the paging group information message. The following describes the specific process for the advanced control station to implement paging in the idle mode terminal in this scenario. The process is as shown in Figure 6, and includes the following steps:

Step 600: The terminal enters the idle mode, and the advanced control station interacts with the paging controller to obtain parameters such as a paging group identifier, a paging controller identifier, a paging cycle, and a paging shift allocated to the terminal, and then sends the a deregistration response message having a paging group identifier, a paging controller identifier, a paging cycle, and a paging offset to the terminal to notify the terminal to enter an idle mode, wherein the paging cycle and paging in the deregistration response message The displacement is in units of frames;

In this step, since the advanced control station is connected to the traditional access network, the paging cycle allocated by the paging controller for the terminal and the paging displacement are counted by the frame of the traditional network, and the advanced control station registers the response. The message also carries the paging cycle and paging shift in units of frames to the terminal.

When the terminal enters the idle mode, the terminal actively sends a registration request message (AAI_DREG-REQ) to the advanced control station to request to enter the idle mode, or the advanced control station wants the terminal to enter the idle mode;

For another example, if the advanced control station wants the terminal to enter the idle mode, the advanced control station may actively interact with the paging controller to assign the paging group identifier to the terminal, the paging controller identifier, and the paging. The period and the paging displacement, and then actively send a deregistration response message including the above information to the terminal to request the terminal to enter the idle mode, as shown in FIG. 5.

Step 601: When the network side wants to page the terminal in the idle mode, the advanced control station determines the superframe number used for the paging terminal according to the paging cycle and the paging displacement allocated to the terminal in the frame counting unit;

In this step, if the advanced control station receives the paging notification message of the paging controller, the advanced control station determines the paging period for the paging terminal according to the paging cycle of the paged terminal and the paging displacement of the paged terminal. Superframe, specifically calculating the superframe number of the paging terminal according to the following formula:

N sup erframe― floor of [(paging cycle * w + paging offset) I q];

In the above formula, ; Vsup /ra/^ represents the superframe number of the paging terminal;

The paging cycle indicates a paging cycle in units of frames;

Paging offset indicates a paging shift in units of frames;

Ncurrent sup erframe table current super nickname;

12; q indicates the number of frames included in the superframe. Currently, the superframe contains 4 frames.

Step 602: The advanced control station determines a specific frame number for sending the paging broadcast message in the superframe for the paging terminal according to the paging cycle and the paging displacement in the frame counting unit;

In this embodiment, when the advanced control station and the terminal determine that the time domain hash parameter is not indicated by the paging group information message, the advanced control station calculates the paging period and the paging displacement allocated by the terminal according to the following formula. Send the frame number of the paging broadcast message containing the terminal information:

Npaging frame― {paging cycle * + paging offset) od q;

In the above formula, Npaging_finme represents a frame number carrying the paging broadcast message; and paging cycle represents a paging cycle in units of frames; Paging offset indicates a paging shift in units of frames;

Ncurrent _ sup erframe table The current super middle nickname;

12;

A page broadcast message containing the paged terminal information is sent.

The process of implementing paging on the terminal side is as shown in FIG. 7, and includes the following steps:

Step 700: The terminal receives the de-registration response message sent by the advanced control station, and calculates a super-frame number (Nnext-listening-superframe) that enters the paging listening interval by using a frame-by-frame paging period and paging displacement information obtained therefrom;

In this step, the specific formula can use the following formula:

N sup erframe― floor of [(paging cycle * w + paging offset) I q];

The paging cycle indicates a paging cycle in units of frames;

Paging offset indicates a paging shift in units of frames;

Ncurrent sup erframe table current super nickname;

Indicates the number of bits allocated for the superframe number. The number of bits currently allocated for the superframe number is generally 12;

Step 701: After the terminal calculates the paging monitor superframe number, the terminal enters the idle state of the idle mode, until the advanced control station sends the same superframe as the paging monitor superframe number, and the terminal enters the paging listening interval. The length of the paging listening interval is the duration of one superframe (ie, the length of 4 frames); Step 702: The terminal calculates the paging broadcast message that the terminal needs to parse according to the received paging period and paging displacement in units of frames. The frame number where it is located; In this embodiment, when the advanced control station and the terminal determine that the time domain hash parameter is not indicated by the paging group information message, the terminal calculates the frame number of the paging broadcast message that the terminal needs to parse by using the following formula:

Nlpaging frame― {paging cycle * + paging offset) od q;

In the above formula, Npaging_finme represents a frame number that carries the paging broadcast message; and a paging cycle represents a paging cycle in units of frames;

Paging offset indicates a paging shift in units of frames;

Ncurrent sup erframe table current super nickname;

p represents the number of bits allocated for the superframe number, and the number of bits currently allocated for the superframe number is generally

12;

Step 703: The terminal parses the paging broadcast message included in the corresponding frame according to the calculated frame number in the superframe, and then determines whether the received paging broadcast message includes a paging identifier matching the self, that is, determining the terminal. Whether it is paged, if the terminal is paged (that is, the paging broadcast message contains a paging identifier matching with itself), the terminal performs location update or network reentry operation according to the indication in the paging message. . Otherwise, the terminal performs the next monitoring;

When the terminal performs location update or network reentry, the paging request message and the paging interval included in the ranging response message and the paging displacement should also be in the frame of the traditional network, and further, The number of bits occupied by the paging request message and the paging displacement in the ranging request message and the ranging response message is the same as the number of bits occupied by the paging cycle and the paging displacement in the conventional art. If the terminal is not paged, the terminal calculates the superframe number that enters the paging listening interval for the next time, and enters the paging unreachable state. In addition, when the terminal has data to be sent, the terminal can perform network re-entry at any time and end the idle mode in advance.

In the above embodiments 1 to 3, when the terminal accesses the advanced control station, the type of paging identifier supported by the advanced control station can be obtained by the superframe header broadcasted by the advanced control station (ie, the paging identifier is The registration identifier is also the MAC address hash). Thereafter, the advanced control station and the terminal can negotiate to determine the paging related parameters, for example, in the first area of the advanced control station, the terminal allocates a paging period and a paging shift in a frame or a superframe as a counting unit, and whether to pass The paging group information message indicates a time domain hash parameter, etc., and the negotiation process can be seen in FIG. 8.

Alternatively, the advanced control station may indicate the terminal by using the sent superframe header, and the advanced control station supports the traditional technology identifier or the advanced technology identifier, so that the terminal can determine the paging identifier type according to the indication in the superframe header. For example, when the advanced control station supports the advanced technology identification, the terminal can determine the advanced paging identifier in the advanced technology identification to determine the paging identification type, and the paging related parameters, such as the first area of the advanced control station is the terminal. Allocating a paging period and a paging shift in units of a frame or a superframe, and indicating whether a time domain hash parameter or the like is indicated by a paging group information message, and the terminal follows a preset mode (such as a system default parameter setting) Can be determined.
