Description
Technical Field
The present invention relates to the field of mobile communications, and in particular, to a QoS (Quality of Service) policy configuration technique.
Background
A non-PCC (Policy and Charging Control) network architecture of 3G (The 3rd Generation, third Generation Mobile communication technology), which is a conventional GPRS (General Packet Radio Service)/UMTS (Universal Mobile Telecommunications System) network and does not use a PCC architecture. When the SGSN (Serving GPRS Support Node) receives the user access request, it will go to the HLR (Home Location Register) to verify the validity of the user. Meanwhile, the HLR will transfer the QoS policy of the user to the SGSN. When a user is activated, the SGSN transmits a QoS policy to a terminal, an RNC (Radio Network Controller) and a GGSN (Gateway GPRS Support Node) through an activation message, and each Network element allocates resources to the user according to the QoS policy. The QoS policy mainly includes service classification, maximum rate, guaranteed rate, service processing priority, and the like. The QoS strategy of the user is completely configured in the HLR, and the QoS strategy of the user can be only modified by a method of modifying the HLR configuration and can be only used when the user accesses the network next time.
Because the QoS strategy of the non-PCC architecture cannot be dynamically changed, the requirement of the service change of the user cannot be met. The PCC architecture is defined in 3GPP (3rd Generation Partnership Project). In the PCC architecture, a PCRF (Policy and Charging Rules Function) collects user information and service information, and determines a QoS Policy of a user by using the information as input. The QoS policy defines rules in which the decision conditions are specified, and the QoS policy to be used when the conditions are satisfied. The PCEF (Policy and Charging Enforcement Function) is a QoS Policy Enforcement node, and enforces the QoS Policy issued by the PCRF. And when detecting that the user meets the conditions in the QoS strategy, the PCEF provides service for the user by using the corresponding QoS strategy.
The inventor finds that at least the following problems exist in the prior art: under the non-PCC architecture, the QoS policy of the user is determined by the HLR, and the user cannot change in the process of using the service. Under the PCC architecture, the PCRF cannot perceive the state of the cell where the user is located. For example, when the cell where the user is located is congested, the network should perform speed reduction processing on a part of users with large traffic (for example, a user using P2P (point-to-point) service generally occupies a large bandwidth for P2P service), but because both the GGSN and the PCRF cannot know, other users cannot access the network, or the speed is slow. Therefore, how to flexibly configure the QoS policy according to the cell state is an urgent problem to be solved.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
as shown in fig. 1A, a flow chart of a QoS control method according to an embodiment of the present invention is provided, where the method includes:
101. a message including state information of the cell is transmitted.
Optionally, the message including the cell status information may be a special message, for example, a signaling plane message indicates the cell status, or an existing message (e.g., a user plane message) may be extended, and the cell status information of the user is indicated by a newly added cell. The signaling plane message refers to a message for transmitting control information; the user plane message refers to information for transmitting data messages, and for example, when a user accesses a webpage, webpage content returned by the server is transmitted by using the user plane message.
Specifically, if the cell status of the user is represented by extending the existing message, the following may be referred to: a cell can be added to the header of a data packet (e.g., a data packet encapsulated by a GTP tunnel using a gprs (general data transfer platform)) of a user to indicate the cell state information of the user.
It should be noted that the state information of the cell may be a congestion status of the cell, such as being congested or decongested or a congestion level. The message including the cell state information of the user may be sent periodically, or sent when the state of the cell changes, or sent when the location of the cell of the user changes.
In addition, the message including the cell state information of the user may further include a cell identifier to indicate specific cell information; and/or may also include a list of cell users for the cell.
102. And receiving the QoS strategy configured for the users in the cell, wherein the QoS strategy configured for the users in the cell is determined at least according to the state information of the cell.
Specifically, the QoS policy configured according to the cell state may include: when the cell is in a congestion state, the resources allocated to the users in the cell can be adjusted, for example, the speed limit is performed on the specified service (such as the point-to-point P2P service); when the cell releases the congestion, the cell congestion release message can be reported to acquire a new QoS strategy. The embodiment of the present invention is mainly described with respect to a method for determining a QoS policy according to state information of a cell, and in addition, the QoS policy may also be determined in combination with a service classification, a maximum rate of a network, a guaranteed rate required by the service, and the like, which is not limited in the embodiment of the present invention.
103. And controlling the QoS of the users of the cell according to the QoS strategy configured for the users in the cell.
When the configured QoS policy is received, the bandwidth of the user is guaranteed according to the QoS policy, for example, the resource allocated to the user in the cell may be adjusted, for example, the speed limit is performed on a specified service (for example, a point-to-point P2P service occupying a larger bandwidth).
The method embodiment of the invention at least determines the received QoS strategy according to the cell state, thereby achieving the technical effect of realizing flexible configuration of the QoS strategy according to the cell state.
Further, in the embodiment of the present invention, the received QoS policy configured for the user may further include a service type or priority information of the service, and after the received QoS policy is the service type information, the priority of the service may be further queried or determined according to the service type, so that the QoS of the user may be controlled according to the cell state information and the service priority.
Corresponding to the above control method, as shown in fig. 1B, a flow chart of a QoS policy configuration method provided in an embodiment of the present invention is provided, where the method includes:
101', cell state information is obtained.
Optionally, the acquiring the cell state information of the user includes: and identifying the received user plane message or signaling plane message to acquire the cell state information of the user. It should be noted that the cell state information of the user may be obtained periodically, and the period may be set according to actual needs, which is not limited in the embodiment of the present invention. Further, it may also be obtained when the cell status changes (e.g. when the user's cell starts to be congested or is decongested).
In addition, the cell state information of the user can be acquired while the received user plane or signaling plane message is identified, so that the cell information, such as which users are in the cell, can be acquired according to the cell identifier and/or the cell user list, and the QoS policy can be configured for the users in the cell.
102' configuring QoS strategy for users in the cell at least according to the acquired cell state information.
In this step, a QoS policy is configured at least according to the cell state information, and when the cell is in a congested state, resources allocated to users in the cell may be adjusted, for example, to limit the speed of a specific service (e.g., a point-to-point P2P service); when the cell is decongested, a new QoS policy may be configured to readjust the resources allocated to the user. The embodiment of the present invention is mainly described with respect to a method for determining a QoS policy according to state information of a cell, and in addition, the QoS policy may also be determined in combination with a service classification, a maximum rate of a network, a guaranteed rate required by the service, and the like, which is not limited in the embodiment of the present invention.
It should be noted that, when configuring the QoS policy for the users in the cell according to the acquired state information of the cell, the QoS policy configuration at the cell level may be performed without distinguishing the users, that is, the same QoS policy is used for all the users in the cell; the user-level policy configuration may also be performed, and a QoS policy is configured for each user in the cell individually, or a QoS policy is configured for users in the cell according to information such as service priority or service type, for example, different QoS policies are provided for users who use internet access services or video on demand services.
103', sending the QoS policy configured for the users in the cell.
By sending the QoS policy, the subsequent entity can control the QoS of the user according to the QoS policy, thereby realizing flexible configuration of the QoS policy according to the cell state. For example, when the cell where the user is located is congested, the speed reduction process may be performed on a part of users with large traffic (for example, a user using P2P service generally occupies a large bandwidth in P2P service), so as to guarantee the service quality such as the speed of user access.
In addition, the sent QoS policy configured for the user may further include a service type or service priority information, and the service priority of the service may be determined according to the service type, so that when performing QoS control on the user in the cell according to the configured QoS policy, the bandwidth of the service with the high service priority may be preferentially guaranteed.
Example two:
in this embodiment, a cell indicating a cell state is added in a data packet sent by a user to notify the cell state of the user, for example, a packet header of a user plane message may be extended.
The embodiment of the invention adds a cell in the GTP message header of the data message of the user to indicate the state of the cell where the user is located. And a GTP _ PDU field of the GTP message allows the cell to be added. Specifically, the following may be mentioned:
10000001 cell congestion
In addition, a cell indicating a cell identifier may be added to the GTP header, which may specifically be as follows:
10000000 cell identity
It should be noted that, in the embodiment of the present invention, it is only illustrated which cell is specifically used to represent the cell state or the cell identifier, and there are other possible multiple ways, and the embodiment of the present invention is not limited.
As shown in fig. 2, which is a schematic signaling interaction flow diagram according to the second embodiment of the present invention, an RNC sends a message including cell state information to a core network, and the core network configures a QoS policy, which may specifically be:
201. RNC sends data message to SGSN;
the data message includes information indicating the state of the cell where the user is located.
The information of the cell state information of the user can be sent periodically, or sent when the state of the cell changes, or sent when the location of the cell of the user changes.
202. After receiving the data message, the SGSN identifies the cell representing the cell state information.
In addition, the data packet may further include a cell identifier and/or a cell user list, and the SGSN may also perform identification.
203. SGSN fills the user plane message head sent to GGSN according to the identified cell expressing cell state information.
It should be noted that, the RNC and the SGSN, and the SGSN and the GGSN may all interact through user plane messages.
In addition, if a cell identity and/or cell user list is also identified in 202, it is also sent to the GGSN. The SGSN may also send information such as cell status information, cell id and/or cell user list via direct forwarding.
204. After receiving the user plane message sent by SGSN, GGSN identifies the cell state information.
Likewise, the user plane message may also include a cell identifier and/or a cell user list.
205. And the GGSN identifies the cell state information and reports the cell state information to the PCRF.
After the GGSN identifies the cell state information, the GGSN may report the cell state information again when the cell state changes (for example, congestion occurs or congestion is removed).
In addition, the GGSN can also report the cell identification and/or the cell user list to the PCRF.
If the user plane message sent by the GGSN does not include the cell identifier or the user list, the GGSN may obtain specific cell information, for example, which users are in the cell, by querying the user identifier stored locally and the cell identifier where the user is located, and then report the cell information to the PCRF.
206. And after receiving the information reported by the GGSN, the PCRF configures a new QoS strategy and sends the QoS strategy to the GGSN.
As described in the first embodiment, the PCRF may perform the cell-level QoS policy configuration and may also perform the user-level QoS policy configuration.
Specifically, the PCRF may perform cell-level or user-level QoS policy configuration according to the cell identifier, where the configuration may be performed according to user list information or cell information queried by the GGSN when performing the user-level QoS policy configuration.
207. The GGSN performs subsequent procedures such as notifying the RNC to perform a new QoS policy, etc.
Thus, the RNC can control the QoS of the users in the cell according to the QoS policy.
The solution of the embodiment of the present invention is not only applicable to a network with a PCC architecture, but also applicable to a network with a non-PCC architecture (at this time, the HLR dynamically decides a new QoS policy according to the cell state information, which is similar to the above solution and will not be described in detail).
In addition, the method of the embodiment of the present invention is also applicable to an SAE (system architecture Evolution) network, which uses an evolved SAE network with a PCC architecture, wherein a PCEF is deployed in a P-GW (PDN Gateway) network element. The Mobility Management Entity (MME) performs a function similar to a control plane processing function of the SGSN in the original network, and the Serving Gateway (S-GW) performs a function similar to a user plane processing function of the SGSN in the original network. The location of the P-GW in the network is similar to the GGSN in the original network.
Fig. 3 is a schematic diagram of a signaling interaction flow applied to an SAE network according to a second embodiment of the present invention, which includes:
301. the eNodeB sends a data message to the S-GW;
the data message includes information indicating the state of the cell where the user is located.
The information of the cell state information of the user can be sent periodically, or sent when the state of the cell changes, or sent when the location of the cell of the user changes.
302. And after receiving the data message, the S-GW identifies the cell representing the cell state information.
In addition, the data message may further include a cell identifier and/or a cell user list, and the S-GW may also perform identification.
303. And the S-GW fills the user plane message header sent to the P-GW according to the identified cell representing the cell state information.
It should be noted that the eNodeB and the S-GW, and the S-GW and the P-GW may interact with each other through user plane messages.
In addition, if a cell id and/or a cell user list is also identified in 302, it is also sent to the P-GW.
304. And the P-GW identifies the cell state information after receiving the user message sent by the S-GW.
Likewise, the user plane message may also include a cell identifier and/or a cell user list.
305. And the P-GW identifies the cell state information and reports the cell state information to the PCRF.
After identifying the cell state information, the P-GW may report the cell state information again when the cell state changes (e.g., congestion occurs or congestion is relieved).
In addition, the P-GW can also report the cell identification and/or the cell user list to the PCRF.
If the user plane message sent by the P-GW does not have a cell identifier or a user list, the P-GW may obtain specific cell information, for example, which users are in the cell, by querying the locally stored user identifier and the cell identifier where the user is located, and then report to the PCRF.
306. And after receiving the information reported by the P-GW, the PCRF configures a new QoS strategy and sends the QoS strategy to the P-GW.
As described in the first embodiment, the PCRF may perform the cell-level QoS policy configuration and may also perform the user-level QoS policy configuration.
Specifically, the PCRF may perform cell-level or user-level QoS policy configuration according to the cell identifier, where the configuration may be performed according to user list information or cell information queried by the P-GW when performing the user-level QoS policy configuration.
307. The P-GW performs subsequent procedures, such as notifying the eNodeB to perform a new QoS policy, etc.
The GGSN or the P-GW of the embodiment of the invention can obtain the state information of the cell in real time and report the state information to the PCRF. The PCRF can take the cell state information as an input, configure and issue the QoS policy according to the cell state information. The issued QoS strategy can limit the speed of the appointed service, for example, reduce the bandwidth of the P2P service, thereby ensuring that the user can use the network fairly. The method conforms to the 3GPP architecture, the network architecture is not changed, the private information is not added, and the signaling load is not increased.
In addition, the GGSN or the P-GW may identify the service priority or the service type, and send the service priority or the service type as the QoS policy to the RNC, so that the RNC may control the QoS of the user according to the QoS policy configured by the PCRF and the service type or the service priority information, and the service type or the service priority may be identified by the RNC.
Example three:
in the embodiment of the invention, when the state of a cell changes, such as the cell is congested, RNC or eNodeB reports the state information of the cell through a signaling plane message, GGSN or P-GW receives the message and inquires which users are in the cell, and reports the state information of the cell to PCRF for all or part of the users in the cell, so that the PCRF can realize the QoS strategy configuration of the user level.
As shown in fig. 4, a signaling interaction flow diagram according to a third embodiment of the present invention includes:
401. the RNC sends a message including cell state information to the SGSN.
The cell state information message may be sent periodically, or when the state of the cell changes, or when the location of the cell of the user changes.
The message including the cell state information may further include a cell identity.
402. After receiving the message (including the cell identifier) including the cell state information, the SGSN forwards the message to the GGSN.
403. After receiving the message including the cell state information, the GGSN inquires which users exist in the cell according to the cell identification.
The GGSN locally stores the user identifier and the cell identifier where the user is located, so that which users are in a cell can be queried according to the cell identifier.
It should be noted that, the RNC and the SGSN, and the SGSN and the GGSN may all interact through signaling plane messages.
In addition, it is also possible that which users exist in the cell is not queried, and then in the subsequent step, the QoS policy configuration of the cell level is performed according to the cell identifier.
404. After receiving the information including the cell state information, the GGSN reports the cell state information to the PCRF for each user in the cell.
405. And after receiving the information reported by the GGSN, the PCRF performs user-level QoS policy configuration and sends the configuration to the GGSN.
406. The GGSN performs subsequent procedures such as notifying the RNC to perform a new QoS policy, etc.
After the cell releases the congestion, the RNC also reports the cell congestion release message. The GGSN reports the cell state information (congestion relief event) to the PCRF, and the PCRF issues a new QoS strategy.
The solution of the embodiment of the present invention is not only applicable to a network with a PCC architecture, but also applicable to a network with a non-PCC architecture (at this time, the HLR dynamically decides a new QoS policy according to the cell state information, which is similar to the above solution and will not be described in detail).
In addition, the method of the embodiment of the invention is also suitable for an SAE network, and the evolved SAE network of a PCC architecture is used, wherein the PCEF is deployed in a P-GW network element. The function completed by MME is similar to the control plane processing function of SGSN in original network, and the function completed by S-GW is similar to the user plane processing function of SGSN in original network. The location of the P-GW in the network is similar to the GGSN in the original network.
The scheme is applicable to an SAE network, and as shown in fig. 5 below, is a signaling interaction flow diagram applied to an SAE network in a third embodiment of the present invention, including:
501. the eNodeB sends a message including cell state information to the MME.
The message of the cell state information of the user can be sent periodically, or sent when the state of the cell changes, or sent when the location of the cell of the user changes.
The message including the cell state information may further include a cell identity.
502. After receiving the message (including the cell identifier) including the cell state information, the MME forwards the message to the S-GW.
503. After receiving the message (including the cell identifier) including the cell state information, the S-GW forwards the message to the P-GW.
504. After receiving the message including the cell state information, the P-GW inquires which users exist in the cell according to the cell identification.
The P-GW locally stores the user identifier and the cell identifier where the user is located, so that which users are in the cell can be queried according to the cell identifier.
It should be noted that eNodeB and MME, MME and S-GW, S-GW and P-GW may all interact through signaling plane messages.
In addition, it is also possible that which users exist in the cell is not queried, and then in the subsequent step, the QoS policy configuration of the cell level is performed according to the cell identifier.
505. After receiving the message including the cell state information, the P-GW identifies the cell state information and reports the cell state information to the PCRF for each user.
Here, after recognizing the cell status information, the P-GW may report the cell status information when the cell status is congestion or congestion release.
506. And after receiving the information reported by the P-GW, the PCRF carries out user-level QoS policy configuration and sends the configuration to the P-GW.
507. The P-GW performs subsequent procedures, such as notifying the eNodeB to perform a new QoS policy, etc.
The GGSN or the P-GW of the embodiment of the invention can obtain the state information of the cell in real time and report the state information to the PCRF. The PCRF can take the cell state information as an input, configure and issue the QoS policy according to the cell state information. The issued QoS strategy can limit the speed of the appointed service, for example, reduce the bandwidth of the P2P service, thereby ensuring that the user can use the network fairly. The method conforms to the 3GPP architecture and has no change to the network architecture.
In addition, the GGSN or the P-GW may identify the service priority or the service type, and send the service priority or the service type as the QoS policy to the RNC, so that the RNC may control the QoS of the user according to the QoS policy configured by the PCRF and the service type or the service priority information, and the service type or the service priority may be identified by the RNC.
Example four:
in this embodiment, after detecting a cell state change (e.g., when a cell is congested), the RNC or the eNodeB reports the cell state change through a signaling plane message, and reports a cell user list message to the GGSN or the P-GW. After receiving the cell user list, GGSN or P-GW reports the cell state information to PCRF for each user. And the PCRF configures the QoS strategy according to the information of the user, the cell information and the state of the user.
As shown in fig. 6, a signaling interaction flow diagram of a fourth embodiment of the present invention includes:
601. the RNC sends a message including cell state information to the SGSN.
The message of the cell state information of the user can be sent periodically, or sent when the state of the cell changes, or sent when the location of the cell of the user changes.
The message including cell state information may include a list of cell users.
602. After receiving the message including the cell state information (including the cell user list), the SGSN forwards the message to the GGSN.
603. After receiving the message including the cell state information, the GGSN reports the cell state information to the PCRF for each user.
604. And after receiving the information reported by the GGSN, the PCRF configures a new QoS strategy for each user according to the user list and sends the QoS strategy to the GGSN.
605. The GGSN performs subsequent procedures such as notifying the RNC to perform a new QoS policy, etc.
After the cell releases the congestion, the RNC also reports the cell congestion release message. The GGSN reports the cell state information (congestion relief event) to the PCRF, and the PCRF issues a new QoS strategy.
The solution of the embodiment of the present invention is not only applicable to a network with a PCC architecture, but also applicable to a network with a non-PCC architecture (at this time, the HLR dynamically decides a new QoS policy according to the cell state information, which is similar to the above solution and will not be described in detail).
In addition, the scheme of the embodiment of the invention is also suitable for an SAE network, and the evolved SAE network of a PCC architecture is used, wherein the PCEF is deployed in a P-GW network element. The function completed by MME is similar to the control plane processing function of SGSN in original network, and the function completed by S-GW is similar to the user plane processing function of SGSN in original network. The location of the P-GW in the network is similar to the GGSN in the original network. The scheme is applicable to an SAE network, and as shown in fig. 7 below, is a signaling interaction flow diagram applied to an SAE network in the fourth embodiment of the present invention, including:
701. the eNodeB sends a message including cell state information to the MME.
The message of the cell state information of the user can be sent periodically, or sent when the state of the cell changes, or sent when the location of the cell of the user changes.
The message including cell state information may include a list of cell users.
702. After receiving the message (including the cell user list) including the cell state information, the MME forwards the message to the S-GW.
703. After receiving the message (including the cell user list) including the cell state information, the S-GW forwards the message to the P-GW.
704. After receiving the message including the cell state information, the P-GW reports the cell state information to the PCRF for each user according to the user list.
Here, after recognizing the cell status information, the P-GW may report the cell status information when the cell status is congestion or congestion release.
705. And after receiving the information reported by the P-GW, the PCRF configures a new QoS strategy and sends the QoS strategy to the P-GW.
706. The P-GW performs subsequent procedures, such as notifying the eNodeB to perform a new QoS policy, etc.
The GGSN or the P-GW of the embodiment of the invention can obtain the state information of the cell in real time and report the state information to the PCRF. The PCRF can take the cell state information as an input, configure and issue the QoS policy according to the cell state information. The issued QoS strategy can limit the speed of the appointed service, for example, reduce the bandwidth of the P2P service, thereby ensuring that the user can use the network fairly. The method conforms to the 3GPP architecture and has no change to the network architecture.
In addition, the GGSN or the P-GW may identify the service priority or the service type, and send the service priority or the service type as the QoS policy to the RNC, so that the RNC may control the QoS of the user according to the QoS policy configured by the PCRF and the service type or the service priority information, and the service type or the service priority may be identified by the RNC.
