Description

Method and device for determining service carrying mode The application is submitted to the Chinese Patent Office on June 20, 2011, and the application number is 201110165819.X, and the invention name is

The priority of the Chinese Patent Application, which is incorporated herein by reference. The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for determining a service bearer. BACKGROUND With the development of communication technologies and the diversification of user service requirements, the service types of communication services are continuously enriched, and various data services are expanded on the basis of traditional voice services, for example, short message service, multimedia message service, streaming media service, and the like. In order to adapt to the communication characteristics of various communication services, the service bearer mode of the application in the mobile communication system is also constantly improving.

At present, the service bearer modes applied in the mobile communication system are mainly point-to-point, single-cell multicast, and bearer modes based on the Multimedia Broadcast Multicast Service (MBMS). Among them, the main technologies of each mode. The principle is as follows:

The point-to-point mode refers to a mode in which a communication is performed between user terminals or between a server and a user terminal in a one-to-one mode, for example, a voice communication service, a short message service, and the like between user terminals. In the peer-to-peer mode, the service server establishes and maintains a separate point-to-point link for each user terminal to separately send data streams to the user terminals. The point-to-point method is applicable to the case where the number of user terminals is small and the amount of data transmitted is small, and the data transmission security is high, and the wireless network resources are occupied less. However, this method has the problem of limited capacity, that is, the number of target terminals is large, especially in the case of a large amount of data to be transmitted, the point-to-point bearer service is used for each target terminal, which occupies a large amount of wireless network resources, thereby reducing the number of radio network resources. The transmission efficiency of the service affects the quality of the service.

The single-cell multicast mode is a method of multicasting in a cell. In this mode, parameters such as a group number and a group radio network temporary identifier (G-RNTI) are introduced, so that each initiated service is performed in groups. The single-cell multicast mode is more suitable for the case where the target terminals are concentrated in one cell, and has the advantages of high data transmission efficiency. However, since the single cell multicast mode consumes more radio network resources than the peer-to-peer mode, the method is not applicable to the case where only a few target terminals are distributed in one cell, otherwise network resources are wasted.

The bearer mode of the MBMS is to use the broadcast channel of the MBMS to carry the service, that is, the service to be transmitted is regarded as one service of the MBMS. MBMS supports two modes of multimedia broadcast service and multicast service. It can broadcast multimedia data directly to all target terminals or to a group of target terminals. At present, Long Term Evolution (LTE) introduces a single frequency network (SFN) transmission mode in the access network, that is, an MBSFN transmission mode. The transmission mode is synchronous transmission in multiple cells at the same frequency and at the same time. The MBMS-based bearer mode has higher service transmission efficiency and higher frequency utilization. However, this method is only applicable to the case where a large number of target terminals are distributed in multiple cells, and the integrated wireless network resources and network utilization are not suitable for the case where the target terminals are distributed in a concentrated manner, otherwise network resources are wasted.

It can be seen that the above three service bearers have their own advantages and disadvantages. In actual applications, the service bearer used to implement the service is usually pre-configured by the system. For example, for a streaming media service that usually has a large amount of data, the system may configure the bearer mode of the service to be MBMS, but it may be once. The number of target terminals of the streaming media service is small. In this case, the MBMS mode is still used to waste resources. For example, for short message services that usually have a small amount of data, the system may configure the bearer mode of the service. In the point-to-point mode, the target terminal of the short message service may be the target terminal of the entire network. In this case, the point-to-point method for a large number of target terminals obviously wastes a lot of wireless network resources, which is wasted compared with the direct use of the MBMS method. More network resources, and will also affect the quality of service.

In summary, the prior art has a problem that the network resource utilization rate is low because the service bearer mode cannot be flexibly determined. SUMMARY OF THE INVENTION In view of this, an embodiment of the present invention provides a method and an apparatus for determining a service bearer mode, and the technical solution can improve utilization of network resources.

The embodiment of the invention is implemented by the following technical solutions:

According to an aspect of the present invention, a method for determining a service bearer mode is provided, including: determining, by the network device, distribution information of each target terminal corresponding to the target terminal information according to target terminal information of the current service;

The method can be implemented in a network device to flexibly determine the bearer service according to the distribution of the target terminal of the service. Service bearer mode, so as to achieve the purpose of effectively utilizing network resources.

FIG. 1 is a schematic flowchart of determining a service bearer mode according to Embodiment 1 of the present invention. As shown in FIG. 1 , the process of determining a service bearer mode mainly includes the following steps 101 and 102:

Step 101: The network device determines the distribution information of each target terminal corresponding to the target terminal information of the current service according to the target terminal information of the current service.

In step 101, the network device can be MME according to different service types.

Efficiency, a mobile management entity, or an RNC (Radio Network Controller), or a base station controller (BSC), for example, when implementing SMS or MMS services, the network device can be a 2G network. In the implementation of the Fetion service, the network device may be an RNC in the 3G network; when the cluster service is implemented, the network device may be an MME in the LTE network.

Step 102: The network device determines, according to the determined distribution information of each target terminal, a service bearer mode corresponding to the distribution information of each target terminal as a service bearer mode of the current service.

At this point, the process of determining the service bearer mode ends.

The network device can determine the service bearer mode corresponding to the distribution mode corresponding to the distribution information according to the distribution information of the target terminals of the current service, and avoid the service bearer compared with the prior art. The problem of wasted network resources caused by the unsuitable adaptation of the mode and the actual distribution of the target terminal, thereby improving the utilization of network resources.

In the step 101 of the corresponding process, the network device determines the target terminal information after receiving the attach request sent by the initiating terminal of the current service, and the distribution information of each target terminal determined according to the target terminal information of the current service may be The information about the number of cells in which the target terminals are distributed, the number of target terminals distributed by each cell, and the total number of information of each target terminal, wherein the total number of information of each target terminal may be based on target terminals respectively distributed by each cell. The quantity information determines that the number of target terminals respectively distributed by each cell is added, and the total number of each target terminal is obtained.

The first embodiment of the present invention further provides a preferred implementation manner of the foregoing step 101. Specifically, in the foregoing step 101, the network device determines, according to the target terminal information of the current service, the distribution information of each target terminal corresponding to the target terminal information, where It is implemented by any of the following preferred ways:

A preferred embodiment 1 for determining target terminal distribution information

The network device determines the distribution information of each target terminal according to the latest serving cell information of each target terminal corresponding to the saved target terminal information. In the first preferred embodiment, the network device stores the most recent serving cell information of each terminal, for example, a cell identifier (cell ID). The network devices first determine the nearest destination of each target terminal corresponding to the target terminal information of the current service. The serving cell, the nearest serving cell corresponding to the target terminal is determined as the cell in which the target terminal is currently located, and the number of cells corresponding to each target terminal of the current service is determined according to the nearest serving cell where each target terminal information is located, and The number of target terminals included in each cell is determined. For example, there are a total of five target terminals for this service, which are target terminals 1, 2, 3, 4, and 5, and the most recent serving cells of the five target terminals are saved as shown in the following table.

7 :

According to the saved information, it can be determined that the target terminals of the current service are distributed in three cells, and that the cell 1 has two target terminals, the cell 2 has one target terminal, and the cell 3 has two target terminals.

Preferred Embodiment 2 for Determining Target Terminal Distribution Information

The preferred embodiment 2 is configured to pre-store the correspondence between the communication group, the time segment, and the distribution information for the service characteristics of the group service, and determine the distribution of the target terminal of the current service according to the correspondence. For example, for campus network services, users who join the campus network are usually distributed in the cell covered by the campus network during working hours. Therefore, the campus network communication group (group ID or number segment) and working time period can be saved. And the correspondence between the cells covered by the campus network.

Specifically, the process of determining the distribution information of the target terminal provided by the preferred embodiment 2, as shown in FIG. 2, mainly includes the following steps:

Step 201: The network device determines the communication group where each target terminal corresponding to the target terminal information is located according to the target terminal information of the current service.

In this step 201, the target terminal information of the current service is usually included in the service request sent by the initiator of the service, and the target terminal information may be a specific target terminal number or an identifier of the communication group where the target terminal is located, for example, Cell ID or number segment information. If the target terminal information is a specific target terminal number, the communication number needs to be parsed to determine the corresponding communication group.

Step 202: The network device determines, according to the initiation time of the current service, a time period in which the initiation time is located.

In the actual business process, the execution order of the foregoing steps 201 and 202 can be flexibly determined, for example, can be performed simultaneously, or step 202 can be performed first and then step 201 can be performed.

Step 203: The network device determines, according to the correspondence between the saved communication group, the time segment, and the distribution information, the distribution information corresponding to the determined communication group and the time period in which the initiation time is located, and the distribution information of each target terminal.

So far, the flow of determining the distribution information of the target terminal provided by the preferred embodiment 2 ends.

In the corresponding flow of FIG. 2, if the number of communication groups determined in step 201 is N, it may be determined that the number of cells in each target terminal is N, and the number of target terminals distributed in each cell is the corresponding communication group. The number of target terminals within. Preferred Embodiment 3 for Determining Target Terminal Distribution Information

In the third preferred embodiment, the distribution information of each target terminal of the current service may be determined by sending a broadcast paging message by the network device.

Specifically, the process of determining the distribution information of the target terminal provided by the preferred embodiment 3, as shown in FIG. 3, mainly includes the following steps:

Step 301: The network device broadcasts a paging message.

The implementation in the step 301 needs to define a new paging message on the basis of the existing protocol, and carry the identification ID of the communication group to which the target terminal of the current service belongs.

Step 302: The terminal that receives the paging message determines whether it needs to respond to the paging message, and if yes, performs the subsequent steps, and if not, ends the process.

In the step 302, the terminal determines whether the paging message needs to be responded to, and is determined according to the ID of the communication group included in the paging message. If the terminal belongs to the communication group corresponding to the ID of the communication group included in the paging message, Then respond to the paging message, otherwise it does not respond.

Step 303: Determine, by the terminal that needs to respond to the paging message, to send a response message to the base station corresponding to the cell in the cell. In the step 303, the terminal feeds back a response message to the base station corresponding to the cell, and initiates a special connection establishment process. The special connection establishment process is different from the normal connection establishment process, and the process only needs to be performed to the terminal to the base station. The message3 in the existing connection establishment process is sent, that is, the terminal transmits an RRC Connection Request message (RRC Connection Request) to the base station.

Step 304: The network device instructs each base station to separately report the quantity information of the target terminal in response to the paging message in the corresponding cell.

Step 305: The network device determines distribution information of each target terminal according to the quantity information reported by each base station.

So far, the flow of determining the distribution information of the target terminal provided by the third preferred embodiment ends.

According to the third preferred embodiment, after the base station receives the response message (ie, the RRC connection setup request), the network device determines that the service bearer mode of the current service is a single cell point-to-point mode or a single cell multicast mode. Then, the base station sends a message4 to the target terminal after receiving the command of the network device, that is, sends an RRC connection establishment (RRC)

Connection Setup), the connection establishment process of the terminal is continued. Specifically, the network device is used as the MME as an example, and the connection establishment process between the terminal and the base station is as shown in FIG. 4, which mainly includes:

Step 401: The UE (terminal) sends an Msgl: RA Preable to the eNB. Step 402: The eNB sends an Msg2: RA Response to the UE (message 2: random access response);

Step 403: The UE sends an Msg3: RRC Connection Request to the eNB. Step 404: The eNB sends Msg4 to the UE: RRC Connection Setup (Message 4: RRC Connection Setup); Step 405: The UE sends the RRC Connection Setup to the eNB. Msg5: RRC Connection Setup Complete (message 4: RRC connection setup completed); Step M06, the eNB sends a Connection Request to the MME;

Step 407: The MME sends a Connection Setup to the eNB.

Step 426: The eNB sends an RRC Connection Reconfiguration to the UE. Step 409: The UE sends an RRC Connection Reconfiguration Complete to the eNB.

At this point, the active state (Active State) is entered from the initial state (Idle State).

Step 410: The UE performs data transmission with the MME.

Step 411: The eNB sends an RRC Connection Release to the UE.

If the network device determines that the service bearer mode of the current service is the MBMS mode, the subsequent connection establishment process is not necessary, that is, the base station does not perform the step of sending the message4 to the target terminal and the subsequent process of the step.

In step 305, the network device includes, according to the quantity information reported by each base station, the distribution information of each target terminal, including:

The number of base stations larger than zero in the reported number information is determined as the number information of the cells in which the target terminals are distributed. If the quantity information reported by the base station is zero, it indicates that the target terminal does not exist in the cell corresponding to the base station. If the quantity information reported by the base station is greater than zero, it indicates that the target terminal exists in the cell corresponding to the base station, and therefore, the report is reported here. The number of base stations greater than zero in the quantity information is determined as the number of cells in which each target terminal is distributed;

The quantity information greater than zero reported by each base station is determined as the quantity information of the target terminal respectively distributed by each cell. The foregoing preferred embodiment of the first embodiment of the present invention provides a detailed description of the process of determining the distribution information of the target terminal of the current service according to the information of the target terminal. In the above three preferred embodiments, the preferred embodiment does not require the protocol. The standard is improved, and the implementation is relatively simple. However, since the basis for determining the terminal distribution is the nearest serving cell of the terminal, it is mainly applicable to the case where the terminal moves slowly or the terminal is static. The preferred embodiment 2 is mainly applicable to the group. The foregoing preferred embodiment 3, although the existing protocol standard needs to be improved, the method has a wide application scope and can accurately determine the cell where the target terminal is actually located, and therefore, the determined distribution of each target terminal. The information is more accurate.

The first embodiment of the present invention further provides a preferred implementation manner of the step 102 included in the corresponding process of FIG. 1, that is, determining, according to the distribution information of each target terminal, the service bearer mode corresponding to the distribution information of each target terminal is the service bearer of the current service. A preferred embodiment of the mode.

FIG. 5 is a schematic flowchart of determining a service bearer according to the distribution information of each target terminal. As shown in FIG. 5, the service bearer corresponding to the distribution information of each target terminal is determined according to the distribution information of each target terminal. Service bearer of the service, including:

Step 501: The network device determines, according to the distribution information of each target terminal, the number of cells in which each target terminal is distributed and the number of each target terminal.

Step 502: The network device determines whether the condition is met: the number of cells in which each target terminal is distributed is greater than the second. The threshold is set, and the number of each target terminal is greater than a third set threshold. If yes, go to step 503. If no, go to step 504.

In the step 502, when the number of cells in which the target terminal is distributed is greater than the second set threshold, and the number of the target terminals is greater than the third set threshold, indicating that the number of target terminals is large and widely distributed, the MBMS mode may be adopted. Carry this service to achieve effective use of network resources. The second set threshold and the third set threshold may be respectively set according to the bearer capacity of the network and the current resource utilization of the network.

Step 503: Determine that the service bearer mode of the current service is the MBMS mode.

Step 504: Determine a service bearer mode of the current service as a point-to-point mode or a single cell multicast mode.

At this point, the process of determining the service bearer mode ends.

According to the foregoing process, in step 504 of the corresponding process of FIG. 5, it is determined that the service bearer mode of the current service is a point-to-point mode or a single cell multicast mode. As shown in FIG. 6, the following steps may be included:

Step 601: Determine, according to the distribution information of each target terminal, a cell whose number of target terminals is less than a fourth set threshold, and downlink physical resource block utilization is less than a fifth set threshold.

In the step 601, the downlink physical resource block utilization information of the cell is obtained by the network device from the base station, and the fourth set threshold may be flexibly set according to requirements, and the threshold is smaller than the third set threshold. The fourth set threshold and the fifth set threshold may be specifically determined according to the effective utilization of the network resource, that is, the number of target terminals in the cell is less than the fourth threshold, and the downlink physical resource block utilization is less than the fifth set threshold. When the peer-to-peer method is used, the network resource can be saved with respect to the single-J.

The downlink physical resource block utilization (DL Total PRB Usage) can be obtained from the eNB.

Step 602: Determine to perform the current service in a point-to-point manner for the target terminal that is distributed in the cell determined in step 601.

Step 603: Determine to perform the current service by using a single cell multicast mode for the cells other than the cell determined in step 601.

At this point, it is determined that the service bearer mode of the current service is the end of the process of the point-to-point mode or the single cell multicast mode. Embodiment 2

The second embodiment of the present invention provides another method for determining a service bearer mode. The method can be applied to a network device. By implementing the method in the network device, the security of the communication with high security level can be ensured. , improve the utilization of network resources.

FIG. 7 is a schematic flowchart of determining a service bearer mode according to Embodiment 2 of the present invention. As shown in FIG. 7, the process of determining a service bearer mode mainly includes the following steps: Step 701 - Step 705:

Step 701: The network device determines a security level corresponding to the current service.

Step 702: The network device determines whether the security level corresponding to the current service is lower than the set first threshold. If no, go to step 703. If yes, go to step 704 to step 705. In the step 702, the first threshold is determined according to the security requirements of the system for the communication service. For example, if the security level is higher and the corresponding security requirement is higher, if the security requirement of the service in the system is high, Then, the first threshold is set to be large, and the security requirement of the service in the system is low, and the first threshold may be set to be small.

Step 703: Determine that the bearer mode of the current service is point-to-point, and the process ends.

Step 704: The network device determines the distribution information of each target terminal corresponding to the target terminal information of the current service according to the target terminal information of the current service.

Step 705: The network device determines, according to the determined distribution information of each target terminal, the service bearer mode corresponding to the distribution information of each target terminal as the service bearer mode of the current service.

The foregoing step 704 and the step 705 correspond to the step 101 and the step 102 in the first embodiment. The specific execution process of the two steps is described in detail in the first embodiment, and details are not described herein again.

At this point, the process of determining the service bearer mode ends.

In step 701, the network device determines the security level corresponding to the current service, and may adopt the following manner 1 or mode 2:

The first step is to determine the security level corresponding to the current service according to the security level identifier included in the subscription information of the target terminal of the service. For example, the communication group where the target terminal is located may be determined according to the security level identifier included in the subscription information of the target terminal. Corresponding security level, if there is a communication group with a higher security level, it directly determines that the bearer mode of the current service is point-to-point.

In the second mode, the security level corresponding to the service is determined according to the corresponding relationship between the service type and the security level. The technical solution provided by the second embodiment is for a service with a relatively high security level (for example, the security level is not lower than the set first threshold), and the service is carried in a point-to-point manner to ensure the security of the service, and the security level is compared. If the service is low (such as the security threshold is lower than the first threshold), the corresponding bearer mode can be determined according to the distribution of the target terminal, so as to improve the utilization of network resources.

With the technical solutions provided in the first embodiment and the second embodiment, the network device can determine the service bearer mode of the current service, and notify the base station where the target terminal is located when determining the bearer mode or the single cell multicast mode bearer service. In the secondary communication mode, the target communication base station performs the subsequent communication process (that is, the service delivery process). When determining the MBMS mode bearer service, the BM-SC where the target terminal is located can be notified of the current communication mode, which is performed by the BM-SC. Subsequent communication process.

Embodiment 3

The third embodiment of the present invention provides a specific application scenario of the technical solutions provided in the first embodiment and the second embodiment.

FIG. 8 is a schematic structural diagram of a system for determining a service bearer mode according to the first embodiment and the second embodiment of the present invention. As shown in FIG. 8, the system includes a service gateway 801, a service server 802, and a network device 803. The service gateway 801 and the service server 802 can be combined, and the network device 803 is a network device corresponding to the target terminal. In different service scenarios, the service gateway and the service server may be the following network entities: For the short message service, the service gateway 801 may be a short message service gateway (SMS-IWMSC), and the service server 802 may be a short message. center;

For the MMS service, the service gateway 801 can be a multimedia message service gateway (WAP-GW), and the service server 802 can be a multimedia message center (MMSC);

For the Fetion service, the service server 802 can be a Fetion service server. If the terminal uses the PC client/WWW mode to access the network, the service gateway 801 can be an Internet Short Message Gateway (ISMG). If the terminal uses the terminal client mode to access the network, no service is required. The gateway 801 can directly log in to the Fetion platform; if the terminal adopts the access mode of the WAP, the service gateway 801 can be a WAP gateway.

The system shown in Figure 8 is different in different network architectures and services. The following describes the different application scenarios.

FIG. 9 is a schematic flowchart of determining a service bearer mode in an LTE network architecture. As shown in FIG. 9, the method mainly includes the following steps:

Step 901: The calling communication terminal initiates a connection establishment request, and completes a connection establishment process with the eNB. Step 902: The calling terminal sends an attach request (NAS service request) to the source MME.

Step 903: The source MME sends the related information of the current service to the service server by using the service gateway.

In the step 903, the source MME sends the related information of the current service, and sends the information after the authentication of the calling terminal is passed. The source MME may send the related information of the current service to the service gateway through the SGW (Signaling Gateway) and the PDN-GW (Packet Data Network Gateway). Moreover, if the service does not pass through the service gateway, it can be directly sent by the source MME to the service server. The relevant information of the service includes the type of the service and the information of the target terminal.

Step 904: The service server parses the information of the target terminal, and sends the target terminal information to the HSS (Home Subscriber Server) through the service gateway, and notifies the target information of the current communication (this service) through the service gateway. MME;

Step 905: The HSS sends the subscription information of the target terminal to the target MME.

Step 906: The target MME determines the service bearer mode of the current service according to the solution provided in the foregoing Embodiment 2. In the step 906, the target MME, as the network device, can determine the service bearer mode of the current service according to the subscription information of the target terminal provided by the SS according to the information about the current communication provided by the service server. If the target MME determines the service bearer mode of the current service according to the technical solution adopted by the foregoing embodiment 1, the HSS does not need to send the subscription information of the target terminal.

So far, the process of determining the service bearer mode in the LTE network architecture ends.

For the cluster service in the LTE architecture, the process of determining the service bearer mode is the same as that of the foregoing process in Figure 9. The difference between the service gateway and the service server is different. FIG. 10 is a schematic flowchart of determining a bearer mode of a short message or a multimedia message service in a 2G network architecture, as shown in FIG. 10, which mainly includes the following steps:

Step 1001: The calling communication terminal initiates a connection establishment request, and completes a connection establishment process with the BTS (Base Transceiver);

Step 1002: The calling terminal sends an attach request (NAS service request) to the source BSC;

Step 1003: The source BSC sends the related information of the current service to the service server by using the service gateway.

In the step 1003, the source BSC can send related information of the current service to the service gateway through the SGSN (GPRS service support node) and the GGSN (Gateway GPRS support node). Moreover, if the service does not pass through the service gateway, it can be directly sent by the source BSC to the service server. The relevant information of the service includes the type of the service and the information of the target terminal.

The device is an RNC. The specific implementation is not mentioned here.

For the group sending service process initiated by the service platform, such as the mobile phone report, the specific implementation process is as shown in FIG. 11 , which mainly includes the following steps:

Step 1101: The cluster service server determines the target terminal information, and sends the target terminal information to the HSS through the cluster service gateway, and sends the target terminal information to the target MME through the cluster service gateway.

Step 1102: The HSS sends the subscription information of the target terminal corresponding to the target terminal information to the target MME. Step «1103. The target MME determines the service bearer mode according to the contract information provided by the HSS.

In the step 1103, the process of determining the service bearer mode by the MME is described in detail in the foregoing Embodiment 1 and Embodiment 2, and is not described herein.

At this point, the process ends.
