Problems solved by technology

[0005] Considering the precious and limited system resources, in order to avoid the invalid occupation of resources, for the scenario where the UE cannot access the network for a long time due to abnormal conditions (such as coverage holes), the gateway should judge that the UE is offline and release the corresponding resources in time. However, under the above simplified architecture, there is currently no relevant method for how the gateway realizes that the UE is offline and performs corresponding operations.

Embodiment 1

[0040] An embodiment of the present invention provides an off-grid processing method, such as figure 2 As shown, the method includes the following steps:

[0041] In step 201, the AP determines whether it needs to notify the gateway that the UE has disconnected from the AP.

[0042] If the judgment result is yes, go to step 202, otherwise go to step 205.

[0043] In step 202, the AP sends a message carrying the identification of the UE to the gateway, notifying the gateway that the UE has disconnected from the AP.

[0044] In step 203, the gateway receives the message carrying the identification of the UE sent by the AP, and starts an off-network timer. If the off-network timer expires, step 204 is performed.

[0045] In step 204, the gateway releases the context of the UE corresponding to the identification and the resource allocated for the UE according to the identification of the UE carried in the message.

[0046]In step 205, the AP maintains data transmission or sig...

Embodiment 2

[0048] An embodiment of the present invention provides an off-grid processing method, such as image 3 As shown, the method includes the following steps:

[0049] In step 301, the AP judges whether the UE is offline.

[0050] If the judgment result is yes, go to step 302 , otherwise go to step 304 .

[0051] Specifically, the AP may store a first preset time. If the AP does not receive a signaling or data transmission request from the UE within the first preset time, the AP judges that the UE has left its coverage area or the UE The power has been cut off. At this time, the AP determines that the air interface connection with the UE has been disconnected, that is, the UE has been disconnected from the network. The AP can also actively send scheduling information to the UE on the downlink channel. If no response message sent by the UE through the uplink channel is received within the second preset time, the AP judges that the UE has left its coverage area or the UE has been p...

Embodiment 3

[0057] An embodiment of the present invention provides an off-grid processing method, such as Figure 4 As shown, the method includes the following steps:

[0058] In step 401, the AP judges whether it needs to actively release the air interface connection with the UE, that is, actively disconnect the UE from the network.

[0059] If the judgment result is yes, go to step 402 , otherwise go to step 404 .

[0060] Specifically, the AP can judge whether it needs to actively release the air interface connection with the UE according to its own resource occupation and preset conditions. For example, the AP can set the maximum number of UEs allowed to access, that is, the threshold of the number of UEs value, when the number of UEs accessing the AP exceeds the threshold, the AP judges that it needs to actively release the air interface connection with a certain UE or multiple UEs; or when the processing performance of the AP itself decreases, the AP judges that it needs to activel...

Abstract

The invention discloses an off-line processing method. The off-line processing method includes: judging whether or not to inform a gateway user that EU (user equipment) is disconnected with an AP (access point) by the AP; if so, transmitting information carrying recognition identity of the UE to the gateway by the AP to inform the gateway that the UE is disconnected with the AP. According to the method, the AP informs the gateway of the recognition identity of the off-line UE when determining the UE is off line, the gateway realizes that the UE is currently in a status of disconnection with a network and starts an off-line timer, and contexts stored for the UE and resources distributed for the UE are released when timeout of the off-line timer occurs, so that storage resources of the gateway are saved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to an off-network processing method and device. Background technique [0002] In the existing LTE (Long Term Evolution, long-term evolution) architecture, the off-network operation of the UE (User Equipment, user equipment) is realized through the detach (detach) process of the NAS (Non Access Stratum, non-access stratum) message, Including the detach process initiated by UE and the detach process initiated by the network side, such as SGSN (Serving GPRS Support Node, GPRS service support node; GPRS, General Packet Radio Service, General Packet Radio Service) due to O&M (Operation & Maintenance, operation and maintenance) reasons. service) / MME (Mobility Management Entity, mobile management entity) triggered detach process, etc. If the MME realizes that there has been no communication with the UE for a long time, the MME will also trigger an implicit detach process, specific...
