Description

The present invention claims the priority of the Chinese patent application filed on October 20, 2010, the Chinese Patent Office, the application number is 201010520647.9, and the invention name is "a processing method and equipment for a business request". The entire contents of which are incorporated herein by reference. Technical field

The present invention relates to the field of communications technologies, and in particular, to a method and a device for processing a service request. Background technique

The purpose of the Service Request process is to change the EMM (EPS Mobility Management) status of the UE (User Equipment) from EMM-IDLE when there is uplink data or signaling to be sent. The state transitions to the EMM-CONNECTED state and establishes an air interface and an S1 bearer. The service request process is initiated by the UE, and when the UE has signaling or data transmission in the EMM-IDLE mode, the process may be triggered by a network initiated paging procedure.

It should be noted that the UE needs to initiate a service request process in the following situations: (1) The UE receives the paging request message in the EMM-IDLE state;

(2) The UE has a pending (to be processed) user data transmission in the EMM-IDLE state;

(3) The UE has pending uplink signaling in the EMM-IDLE state;

(4) When the UE is in the EMM-IDLE or EMM-CONNECTED state, initiate a CS (Circuit Switched) fallback request;

(5) When the UE is in the EMM-IDLE or EMM-CONNECTED state, it receives a CS fallback request;

(6) The UE has pending uplink CDMA (Code Division Multiple Access) 2000® signaling in the EMM-IDLE state. In addition, in an actual application, a UE with an eMPS (Enhancement for Multimedia Priority Service) subscription has an access level of 11-15, and the access level is different from that of a normal UE. In the access class barring mechanism, UEs with access levels 11-15 and normal UEs can use different control policies.

When the UE initiates a service request, the RRC (Radio Resource Control) connection process carries a high-priority cause indication and is transmitted to the eNB (Evolved Node B, Mobility Management Entity, mobility management). Entity) After receiving the Service Request message carrying the high priority cause indication, the eNB and the MME preferentially process the connection request and the bearer establishment process of the UE.

In carrying out the process of the present invention, the inventors have found that at least the following problems exist in the prior art:

After the UE initiates the service request process, the UE enters the EMM-SERVICE-REQUEST-INITIATED state and waits for a response message from the MME to return. At this time, if the UE receives the downlink data or the related signaling again in the EMM-SERVICE-REQUEST-INITIATED state, the UE waits for the subsequent action after the service request process is completed.

However, if the UE receives high priority service related data or high priority service related signaling in the EMM-SERVICE-REQUEST-INITIATED state, the high priority service cannot be prioritized. Summary of the invention

Embodiments of the present invention provide a method and a device for processing a service request, so as to preferentially process a high priority service.

In order to achieve the above objective, an embodiment of the present invention provides a method for processing a service request, including:

In the first service request process, when the second service request is received, the service request information of the second service request process is obtained from the second service request; Determining whether to continue to execute the first service request process according to the service request information of the second service request process and the service request information of the first service request process; if yes, continuing to execute the first service request process; Otherwise, the second service request process is performed.

An embodiment of the present invention provides a processing device for a service request, including:

a receiving module, configured to receive a second service request in the first service request process, and an acquiring module, configured to acquire, when receiving the second service request, a second service request received from the receiving module The service request information of the second service request process; the determining module, configured to determine, according to the service request information of the second service request process acquired by the obtaining module, and the service request information of the first service request process, whether to continue to execute the first Business request process;

FIG. 2 is a schematic structural diagram of a processing device for service request according to Embodiment 2 of the present invention. detailed description

The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings and embodiments.

The purpose of the service request procedure is to transfer the EMM state of the UE from the EMM-IDLE state to the EMM-CONNECTED state when there is uplink data or signaling to be sent, and Establish air interface and si bearer. The UE indicates the reason of the request when initiating the service request, for example, MO (uplink) signaling trigger, MO data trigger, MT (downlink) trigger, high priority access, and the like.

In addition, in the LTE (Long Term Evolution) system, the eMPS service can be supported, and the eMPS service has a higher priority than the normal service. If the UE triggers the service request due to the eMPS service, it will carry the high priority access reason value. When the priority indication is received, the network will preferentially process the access control and the bearer resource allocation. Therefore, because the eMPS service has a higher priority, the eMPS service request process may still succeed when the network is congested or the resources are insufficient and the normal service request process fails.

In the prior art, if the UE triggers the service request process, if subsequent data or signaling arrives before the process is completed, the UE buffers the subsequently arrived data and signaling, and waits until the service request process is completed. carried out. However, if the subsequent high-priority service-related data or signaling arrives, the delay of the high-priority service may be increased due to network congestion.

The embodiments of the present invention provide a method and a device for processing a service request, so as to ensure that a service with high priority can be preferentially processed by the network, reduce the delay of the high priority service, and avoid network overload or Insufficient resources increase the latency of high-priority services.

The technical solutions in the present invention are clearly and completely described in the following with reference to the accompanying drawings in which: FIG. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. The first embodiment of the present invention provides a method for processing a service request, where the method is applied to the process of at least two service requests, and the current service request process (in the embodiment of the present invention, the first service request process is taken as an example) Before the completion, a new service request (in the embodiment of the present invention, the second service request process is taken as an example) is triggered (for example, receiving In the scenario of new data or signaling, as shown in FIG. 1, the method includes the following steps: Step 101: In a first service request process, the UE receives a second service request. The first service request process refers to when the execution process of the current service request process is not completed, and the second service request refers to receiving new data or signaling before the execution process of the current service request process is completed. When new data or signaling will trigger the second service request process.

In the embodiment of the present invention, the first service request process includes, but is not limited to, an EMM-SERVICE-REQUEST-INITIATED state in the first service request process, or an EMM-CONNECTED state in the first service request process. For convenience of description, the EMM-SERVICE-REQUEST-INITIATED state is taken as an example in the embodiment of the present invention.

Specifically, in the EMM-SERVICE-REQUEST-INITIATED state of the first service request process, when data or related signaling (ie, data or signaling corresponding to the second service request process) is received, the second is received. The service request, that is, the second service request process is triggered.

Step 102: When receiving the second service request, the UE obtains service request information of the second service request process from the second service request.

The service request information includes, but is not limited to, the priority information of the second service request process, that is, the UE obtains the priority information of the data or signaling corresponding to the second service request process from the second service request.

In the embodiment of the present invention, the application layer indicates whether the underlying service is a high-priority related service or a normal service. For the eMPS service, when the service request is initiated, the network preferentially processes the high-priority service request.

Step 103: The UE determines, according to the service request information of the second service request process and the service request information of the first service request process, whether to continue to execute the first service request process; if yes, go to step 104, otherwise, go to step 105.

The service request information of the second service request process is the priority information of the second service request process; the service request information of the first service request process is the priority information of the first service request process. In the embodiment of the present invention, for the eMPS service, a high priority (that is, a high priority access cause value) may be used in the service request process, and for a normal service (for example, a PS (Packet Switching) service, etc.) The service request process uses a normal processing level, and based on the priority information, the UE can preferentially process the service with high priority according to the priority information, in order to ensure that the service with high priority (eMPS service) is preferentially processed. .

Therefore, this step can further include:

Step (1), the UE acquires priority information of the first service request process, and determines whether the priority information of the first service request process is a priority of the preset level. The priority of the preset level includes, but is not limited to, a high priority corresponding to the eMPS service.

It can be seen that, by determining whether the priority information of the first service request process is the priority of the preset level, it can be determined whether the first service request process is a service corresponding to the high priority, and then determining whether the first service needs to be preferentially processed. Request process.

If the priority information of the first service request process is the priority of the preset level, step (2) is performed; if the priority information of the first service request process is not the priority of the preset level, step (3) is performed.

Step (2), the judgment result is that the UE needs to continue to execute the first service request process. Specifically, because the priority information of the first service request process is a high priority, the actual application needs to preferentially process the high priority service. In this case, regardless of whether the priority information of the second service request process is a high priority, The first service request process needs to be processed preferentially, that is, the UE needs to continue to execute the first service request process.

In step (3), the UE determines whether the priority information of the second service request process is the priority of the preset level. The priority of the preset level includes, but is not limited to, a high priority corresponding to the eMPS service.

It can be seen that, when the first service request process is not the service corresponding to the high priority, whether the second service request process is determined by determining whether the priority information of the second service request process is the priority of the preset level The service corresponding to the high priority, and then determines whether the second service request process needs to be prioritized.

If the priority information of the second service request process is the priority of the preset level, then Step (4); If the priority information of the second service request process is not the priority of the preset level, step (5) is performed.

Step (4), the judgment result is that the UE needs to perform the second service request process.

Specifically, since the priority information of the first service request process is not a high priority, and the priority information of the second service request process is a high priority, the actual application needs to preferentially process the high priority service. Prioritize the second business request process, ie

The UE needs to perform a second service request procedure.

Step (5), the judgment result is that the UE needs to continue to execute the first service request process. Specifically, since the priority information of the first service request process and the second service request process are not high priority, the UE needs to continue to execute the first service request process.

In summary, in the embodiment of the present invention, if the UE is in

In the EMM-SERVICE-REQUEST-INITIATED state, when the data of the high priority bearer is received, or the signaling related to the high priority bearer (for example, the bearer setup request or the PDN connection setup request, etc.), the second The priority information of the business request process is high priority, in which case:

If the service request process when the UE enters the EMM-SERVICE-REQUEST-INITIATED state is triggered by normal data or signaling (that is, the priority information of the first service request process is not high priority), the UE needs to perform the second service. Request process

If the service request process when the UE enters the EMM-SERVICE-REQUEST-INITIATED state is triggered by high priority service related data or signaling (ie, the priority information of the first service request process is high priority), the UE continues. The previous first business request process. That is, when the UE subsequently receives new data or signaling, the UE will continue to execute the current first service request procedure.

Step 104: The UE continues to execute the first service request process.

Step 105: The UE performs a second service request process.

Specifically, in the process of the UE performing the second service request, the UE needs to suspend the previous service request process (the first service request process), and perform a new service request process (the second service request process), and in the RRC connection process. Lieutenant RRC cause (cause) is set high priority. That is, the UE sends a SERVICE REQUEST message or an EXTENDED SERVICE REQUEST message to the mobility management entity (for example, the MME), and the RRC cause in the RRC message conveying the SERVICE REQUEST message or the EXTENDED SERVICE REQUEST message is the priority of the preset level (high priority) ).

Step 106: The MME preferentially processes the high priority service request process. It can be seen that when the UE performs the first service request process, the MME needs to process the first service request process; when the UE performs the second service request process, the MME needs to process the second service request process.

Specifically, in the existing protocol, if the MME receives multiple service request messages, the MME defines the behavior of the MME. If the MME receives the subsequent service request message before the first service request process is completed, the subsequent MME receives the subsequent service request message. If the content of the service request message is different from the content of the previous service request message, the MME will continue to execute the previous service request process without processing the subsequent service request message. However, after the high-priority service, the MME and the eNB need to prioritize the service request process related to the high-priority service.

Therefore, in the embodiment of the present invention, if the MME receives a service request message, and the RRC cause value does not carry the high priority, the MME receives the carried before the service request process (the first service request process) is completed. Priority indication (high priority) service request message (including SERVICE REQUEST message due to EPS service, EXTENDED SERVICE REQUEST message due to CS service, etc.), the MME will continue to process subsequent received high priority service requests. The process (second service request procedure), and sends a context establishment procedure with an indication of priority to the eNB.

It can be seen that, in the embodiment of the present invention, the service with high priority can be preferentially processed by the network, the delay of the high priority service is reduced, and the delay of increasing the high priority service due to network overload or insufficient resources is avoided. problem. Based on the same inventive concept as the above method, the second embodiment of the present invention further provides a processing device for processing a service request. As shown in FIG. 2, the method includes: The receiving module 11 is configured to receive the second service request in the first service request process, and the acquiring module 12, configured to receive the second service request from the receiving module 11 when receiving the second service request Obtaining service request information of the second service request process;

If the priority information of the first service request process is not the priority of the preset level, determining whether the priority information of the second service request process is a priority of the preset level;

If the priority information of the second service request process is the priority of the preset level, the determination result is that the second service request process is performed;
