Description

Connection management technology for wireless network mobility programs Related application

The present application claims the priority of the U.S. Provisional Patent Application Serial No. 61/806,821, filed on March 29, 2013, the entire disclosure of which is hereby incorporated by reference.

Embodiments of the present invention are generally related to communication between devices in a broadband wireless communication network.

In a wireless network such as an Evolved Universal Terrestrial Radio Access Network (E-UTRAN), a Home evolved Node B (HeNB) may be deployed. In order to implement a femtocell, the tiny cells provide wireless network access in a small area such as an office or a home. In various embodiments, a local gateway (Local Gateway; L-GW), in order to improve the Packet Data Network (PDN) access in the general area of the HeNB service. In some examples, the L-GW can be co-occupied with the HeNB. In the following, such an L-GW will be referred to as a "co-structured L-GW." In other examples, the L-GW can be co-constructed with a Serving Gateway (S-GW) on an independent gateway (GW). In the following, such an L-GW will be referred to as an "independent L-GW."

A User Equipment (UE) served by an HeNB can communicate with a PDN such as the Internet through a L-GW. More specifically, the UE does not unload the selected Internet Protocol (IP) Traffic Offload at the Local Network (SIPTO@LN) via a core packet network. The PDN connection is used to communicate with the PDN via the L-GW. The SIPTO@LN PDN connection may be required and/or desired to be released when an action event occurs based on the UE moving away from the coverage area of the L-GW. However, traditional connection management techniques may not define the appropriate or optimal procedure for releasing certain SIPTO@LN PDN connections.

The present invention describes a connection management technique for a wireless network mobile program. In an embodiment, for example, an Evolved Packet Core (EPC) node may include a processor circuit for performing one of the following: receiving a user equipment (UE) One of the action procedures to notify; decide whether to release a packet data network (PDN) connection provided by a local gateway (L-GW) of the UE; and respond to a decision to release one of the PDN connections provided by the L-GW, and A separate request message or a delete session request message is transmitted to initiate a procedure for releasing the PDN connection provided by the L-GW. Other embodiments are also described, and the scope of the patents of these other embodiments is claimed.

FIG. 1 illustrates an operating environment 100 such as may represent one of the various embodiments. More specifically, operating environment 100 may represent some embodiments in which a UE may establish a SIPTO@LN PDN connection using a co-located L-GW. As shown in FIG. 1, a UE 102 communicates with a HeNB 104 via a Uu interface. The HeNB 104 communicates with a Mobility Management Entity (MME) 106 via an S1-MME interface and communicates with a Serving Gateway (S-GW) 108 via an S1-U interface. The MME 106 communicates with the S-GW 108 via an S11 interface connection. The S-GW 108 communicates with a PDN Gateway (P-GW) 110 via an S5 interface connection. P-GW 110 via An SGi interface is connected to connect to the Internet 120. Co-constructed with HeNB 104 is an L-GW 112, which is also connected to the Internet 120 via an SGi interface connection. The UE 102 does not communicate with the Internet 120 via the P-GW 110, but can establish a SIPTO@LN PDN connection to the Internet 120 via the L-GW 112. Using the SIPTO@LN PDN connection to communicate with the Internet 120 enables the UE 302 to avoid delays associated with the use of the core packet network.

FIG. 2 illustrates an operating environment 200 such as may represent one of the various embodiments. More specifically, operating environment 200 may represent certain embodiments in which UE 102 of FIG. 1 moves away from HeNB 104. As shown in FIG. 2, an action event 202 occurs as the UE 102 moves away from the HeNB 104 and toward an eNB 204. During the course of the action event 202, the UE 102 exits the coverage area 203 of the HeNB 104. The eNB 204 communicates with an MME 206 via an S1-MME interface connection and communicates with an S-GW 208 via an S1-U interface connection. The MME 206 is connected to the S-GW 208 via an S11 interface, and the S-GW 208 is in communication with the P-GW 110 via an S5 interface connection. The MME 206 also communicates with the MME 106 via an S10 interface connection.

In response to action event 202, a mobile procedure can be performed in accordance with UE 102 establishing a service connection via eNB 204. The UE 102 can communicate with the eNB 204 via a Uu interface connection (not shown). If the UE 102 is in a connected mode at the time of the action event, the action program may include a connected mode action procedure such as a handover procedure. If the UE 102 is in an idle mode at the action event, then the course of action The sequence may include an idle mode action program such as a tracking area update program or a service request program. If the UE 102 has established a SIPTO@LN PDN connection to the Internet 120 prior to the action event 202, the SIPTO@LN PDN connection may not be available after the action event 202 because the UE 102 has moved out of the HeNB 104. The scope. Therefore, it may be desirable to release the SIPTO@LN PDN connection after the action procedure.

FIG. 3 illustrates an operating environment 300 such as may represent one of the various embodiments. More specifically, operating environment 300 may represent some embodiments in which a UE may establish a SIPTO@LN PDN connection via a separate L-GW. As shown in FIG. 3, a Home Home Network (LHN) 301 includes a UE 302, HeNBs 304 and 306, and an L-GW 308 co-constructed with an S-GW 310. In the example shown in FIG. 3, HeNB 304 includes a serving HeNB of UE 302 and communicates with UE 302 via a Uu interface connection. HeNBs 304 and 306 communicate with S-GW 310 via respective S1-U interface connections. One of the MMEs 312, one S-GW 314, and one P-GW 316, respectively, which may be included in a service provider network, are disposed outside of the LHN 301. HeNBs 304 and 306 communicate with MME 312 via respective S1-MME interface connections and communicate with S-GW 314 via respective S1-U interface connections. The MME 312 communicates with the S-GW 314 via an S11 interface connection. The S-GW 314 communicates with the P-GW 316 via an S5 interface connection. P-GW 316 communicates with Internet 120 via an SGi interface connection. The UE 302 does not communicate with the Internet 120 via the P-GW 316. Instead, a SIPTO@LN PDN connection to the Internet 120 can be established via the L-GW 308. Using the SIPTO@LN PDN connection to communicate with the Internet 120 enables the UE 302 to avoid delays associated with the use of the core packet network.

FIG. 4 illustrates an operating environment 400 such as may represent one of the various embodiments. More specifically, operating environment 400 illustrates certain embodiments in which UE 302, such as FIG. 3, moves away from HeNB 304. As shown in FIG. 4, according to an action event 402, the UE 302 moves outside of the LHN 301 and enters the range of an eNB 406. The eNB 406 communicates with an MME 412 via an S1-MME interface connection and communicates with an S-GW 414 via an S1-U interface connection. The MME 412 communicates with the S-GW 414 via an S11 interface connection, and the S-GW 414 communicates with the P-GW 316 via an S5 interface connection. The MME 412 also communicates with the MME 312 via an S10 interface connection.

Due to the action event 402, the UE 302 can move out of the range of the HeNB 304 and thus no longer get a service connection via the HeNB 304. Moreover, because UE 302 moves outside of LHN 301, UE 302 is unable to obtain a service connection from any other HeNB, such as HeNB 306, within LHN 301. Thus, in response to action event 402, a mobile procedure can be performed in accordance with UE 302 establishing a service connection via eNB 406. The UE 302 can communicate with the eNB 406 via a Uu interface connection (not shown). If the UE 302 is in a connected mode at the time of the action event, the action program may include a connected mode action procedure such as a handover procedure. If the UE 302 is in an idle mode at the action event, then the course of action The sequence may include an idle mode action program such as a tracking area update program or a service request program. If the UE 302 has established a SIPTO@LN PDN connection to the Internet 120 prior to the action event 402, the SIPTO@LN PDN connection may not be available after the action event 402 because the UE 302 has moved out of the LHN 301. And the range of HeNBs 304 and 306 has been removed. Therefore, it may be desirable to release the SIPTO@LN PDN connection after the action procedure executed in response to action event 402.

It is worth noting that in various embodiments, an action event may occur based on the UE 302 moving out of the range of the HeNB 304 but remaining within the LHN 301. In some such embodiments, in response to an action event, a mobile procedure can be performed in accordance with UE 302 establishing a service connection via another HeNB within LHN 301. For example, after the action event 404, a mobile procedure can be performed in accordance with the UE 302 establishing a service connection via the HeNB 306. In this case, the UE 302 is still able to communicate with the Internet 120 using the L-GW 308 due to the use of the HeNB 306. Thus, if the UE 302 has established a SIPTO@LN PDN connection to the Internet 120 prior to the action event 404, the UE 302 can still use the SIPTO@LN PDN connection after the action event 404. Therefore, it may be desirable to maintain the SIPTO@LN PDN connection after the action procedure performed in response to the action event 404.

The present invention discloses an improved connection management technique for wireless network mobile procedures. According to some such techniques, after a mobile procedure of a UE, a serving MME of the UE may decide whether to release one of the UEs SIPTO@LN PDN connection. In various embodiments, the serving MME may decide whether to release the SIPTO@LN PDN connection based on whether the UE has logged out of its LHN. In some embodiments, if the serving MME decides that the SIPTO@LN PDN connection should be released, the serving MME may also decide to release one of the SIPTO@LN PDN connections according to whether the UE has any other PDN connection. Appropriate procedures. In various embodiments, the mobile procedure may include a Tracking Area Update (TAU) procedure, and the serving MME may include a new MME that communicates with an old MME of the UE during the TAU procedure. For example, after the MME 312 includes an old MME of the UE 302 and the MME 412 includes one of the new MMEs of the UE 302, the MME 412 may include the serving MME of the UE 302. In some other embodiments, the mobile program can include a handover procedure, and the serving MME can include a target MME for the handover procedure. For example, after the MME 312 includes a source MME and the MME 412 includes a handover procedure for one of the UEs 302 of the target MME, the MME 412 may include the serving MME of the UE 302.

It is worth noting that the techniques described herein are not limited to applications in embodiments of the UE's serving MME that change during a mobile procedure. In various embodiments, the same MME may serve the UE before and after the mobile procedure, and the MME may decide whether to release the SIPTO@LN PDN connection of the UE. Likewise, the serving S-GW of the UE may or may not change during the course of the action. The embodiments are not limited to this context.
